DS Cam Indexer is a specific model of cam indexer, usually referring to a cam indexing mechanism that uses a Double Stop structure. Its core feature is to achieve two output shaft pauses within one input shaft rotation cycle, designed specifically for automation scenarios that require high-frequency intermittent motion, significantly improving production efficiency.
DS Cam Indexer is a type of Shaft Output Cam Indexing Drive,which belongs to the axial cam splitter category. DS Cam Indexer is a high-precision and highly reliable intermittent motion mechanism that can convert the continuous operation of automated equipment into a step-by-step motion. It relies on the seamless fit between the cam and the needle roller, and repeats the transmission along the predetermined cam curve. It inputs continuous rotary drive and outputs intermittent rotation, swinging, or lifting motion.
As a shaft output cam indexer, DS Cam Indexer has the following characteristics:
Output mode: Usually output through a shaft, it can be directly connected to couplings, turntables, flange housings, etc., or indirectly connected to sprockets, synchronous wheels, gears, etc., making it easy to connect with various equipment transmission systems.
Load Capacity: Able to withstand certain radial and axial loads, can meet different load requirements according to different specifications and models, suitable for occasions that require the transmission of large torque.
Positioning accuracy: With high division accuracy, it can achieve precise intermittent motion control and meet the requirements of automated production processes such as packaging and assembly that require high positioning accuracy.
Double Stop: During the 360 ° rotation of the input shaft, the output shaft completes two indexing actions and two pauses (traditional models only have one pause).Example: Input shaft continuously rotates → Output shaft: Rotate 90 ° → Pause → Rotate 90 ° → Pause (cycle)
DS type cam indexer adds a composite cam track on the basis of the traditional structure:
1). Double cam surface:
The main cam controls the first indexing, and the auxiliary cam controls the second indexing, synchronizing and coordinating the motion.
2). Strengthen the bearing system:
Adopt cross roller bearings or double row angular contact bearings to withstand bidirectional loads.
3). High precision roller assembly:
Multiple sets of quenched steel rollers to ensure the repeated positioning accuracy of two divisions (within ± 30 arcsec).
The working principle of DS Cam Indexer is based on a cam mechanism that converts the continuous rotational motion of the input into intermittent rotational motion of the output shaft, as follows:
|
Working principle |
Stage 1: Rotate the input shaft by 0°-180°, and the main convex pushes the output shaft for the first indexing (such as 90 °) → pause. Stage 2: The input shaft rotates 180°-360°, and the secondary convex pushes the output shaft for the second indexing (such as 90 °) → pauses. Cycle: Each time the input shaft rotates once, the output shaft completes two divisions and two machining pauses. |
|
Key components |
mainly composed of cam and needle roller bearings. The cam is the core component, usually a cylindrical cam or a planar cam, and its contour curve is designed according to the required motion law; The needle roller bearing is installed on the indexing plate of the output shaft, in contact with the cam profile. |
|
Motion transmission process |
When the input shaft drives the cam to rotate, the contour curve of the cam interacts with the needle roller bearing. Within certain angular ranges of cam rotation, the cam profile drives the needle roller bearing, causing the indexing disc and output shaft to rotate and achieve indexing motion; In other angle ranges, the needle roller bearing is located in the stationary area of the cam profile, and the output shaft remains stationary, achieving intermittent pauses. By precisely designing the cam profile curve, the rotation angle, pause time, and switching timing of the output shaft can be controlled to meet the requirements of intermittent motion in different application scenarios. |
|
Precision assurance mechanism |
The cam and needle roller bearings are processed and assembled with high precision, and the fit clearance is extremely small. It can be approximated as a gapless transmission, which can effectively reduce motion errors. At the same time, multiple needle roller bearings can simultaneously contact the cam, share the load, further improve the smoothness and accuracy of motion, and enable high-precision indexing positioning. Generally, the indexing accuracy can reach a high level, which can meet the requirements of precise position control in automated production. |
|
Self locking principle |
During the pause stage of the output shaft, due to the characteristics of the cam profile curve, the needle roller bearing will be in a specific position. At this time, the direction of the cam's force on the needle roller bearing makes the output shaft have self-locking characteristics, which can reliably maintain the pause position without displacement due to external forces and other factors, ensuring the stability and reliability of the equipment during operation. |

Compared with other types of intermittent motion mechanisms, DS Cam Indexer has advantages such as high accuracy, smooth operation, and strong load-bearing capacity, as follows:
|
High indexing accuracy |
DS Cam Indexer achieves extremely small motion clearances and even nearly seamless transmission through high-precision cooperation between the cam and needle roller bearings. Its indexing accuracy is usually high, reaching around ± 15 ''~30 '', while traditional intermittent motion mechanisms such as ratchet mechanisms have poor motion accuracy due to structural principles and manufacturing errors, far inferior to DS Cam Indexer. |
|
Good operation stability |
This mechanism relies on the cam profile curve to drive the needle roller bearing to move, and the force changes during the movement are relatively stable with minimal impact and vibration. In contrast, the groove wheel mechanism generates significant acceleration changes during startup and shutdown, resulting in impact and making it unsuitable for high-speed operation. DS Cam Indexer can be used in various situations such as high, medium, and low speeds. |
|
Strong load-bearing capacity |
DS Cam Indexer can usually be designed with multiple needle roller bearings in contact with the cam, which can effectively share the load and thus withstand large radial and axial loads, meeting the requirements for transmitting large torque. For example, the cam indexing mechanism with a curved surface has the highest load-bearing capacity among cam mechanisms. Compared to incomplete gear mechanisms, it can withstand larger loads at the same size. |
|
Reliable self-locking positioning |
During the output shaft pause phase,DS Cam Indexer, based on the characteristics of the cam profile curve, will place the needle roller bearing in a specific position to achieve self-locking, which can reliably maintain the pause position without displacement due to external forces and other factors. However, the intermittent motion mechanism controlled by pneumatic may affect the stability of positioning due to pressure fluctuations and other reasons, and cannot provide such reliable self-locking function. |
|
Compact and efficient structure |
DS Cam Indexer has a compact overall structure, small volume, and occupies less space. It can achieve intermittent motion function in limited space, making it easy to install in various automation equipment. At the same time, its transmission efficiency is high and energy loss is small. Compared with some complex intermittent motion mechanisms, such as planetary indexing cam mechanisms, although the planetary indexing cam mechanism has a large indexing number, its structure is relatively complex. DS Cam Indexer has a simpler and cleaner structure and easier maintenance while ensuring certain performance. |
|
Flexible motion rules |
By designing different cam profile curves, DS Cam Indexer can achieve various motion rules and indexing requirements, which can be customized according to specific application needs. However, the motion rules of ratchet mechanisms are relatively fixed and can usually only achieve simple intermittent rotation, with limited angle adjustment. |
DS Cam Indexer is widely used in automation equipment that requires intermittent motion control due to its high precision, high stability, and strong load capacity. Common scenarios include the following:
|
Packaging and Printing Machinery |
Food and beverage packaging |
In automated filling lines, capping machines, and labeling machines, DS Cam Indexer drives conveyor belts or turntables to achieve intermittent motion, accurately controlling the positioning of packaging containers (such as bottles, cans, and paper boxes) to ensure that filling, sealing, labeling, and other processes are completed in a static state, avoiding material leakage or label deviation. For example, in the production line of mineral water bottles, high-speed intermittent conveying and positioning of 300-500 bottles per minute can be achieved. |
|
Printing equipment |
In multi-color printing machines and label printing machines, intermittent pauses of the printing plate or substrate are controlled through indexing motion to ensure accurate overprinting of various colors of ink and reduce printing deviation. |
|
|
Electronics and 3C product manufacturing |
Component Assembly |
In the automated assembly line of electronic products such as mobile phones and computers (such as battery installation, screen bonding, and screw locking machines), DS Cam Indexer drives a multi station turntable to sequentially pass through different assembly processes, ensuring precise alignment of small components (such as chips and connectors) with an indexing accuracy of ± 15-30 arc seconds. |
|
Detection and Sorting |
In PCB board inspection machines and electronic component screening equipment, workpieces are positioned under visual inspection lenses or sorting mechanisms through intermittent motion, ensuring that detection or sorting actions are completed in a stationary state and improving accuracy. |
|
|

|
Medical equipment assembly |
Used on the assembly line of medical devices such as syringes and infusion sets to control the step-by-step transportation and positioning of components, ensuring the accurate assembly of high-precision parts such as seals and needles. |
|
|
Automotive parts processing and assembly |
Component Processing |
In the processing equipment for automotive bearings, gears, brake pads, and other components (such as multi station drilling machines, grinders), the rotating worktable is driven to achieve intermittent indexing of the workpiece, aligning different surfaces or hole positions with the tool in sequence, completing multi process continuous processing, and improving production efficiency. |
|
Automated assembly |
On the assembly line of automotive instrument panels and wiring connectors, workpieces are accurately delivered to tightening, welding, testing and other workstations through intermittent motion, meeting the high cycle rate (60 times per minute) and high stability requirements of automotive manufacturing. |
|
|
Light Industry Machinery and Daily Necessities Production |
Home appliance manufacturing |
Used in the assembly line of components such as washing machine drums and refrigerator door hinges to control the step-by-step transfer of workpieces, and cooperate with robots or automated robotic arms to complete riveting, welding, and other operations. |
|
Processing of daily necessities |
In the production lines of lighters, cosmetic bottle caps, and toy parts, the drive turntable realizes the switching of workpieces between injection molding, coloring, assembly, and other processes, balancing efficiency and accuracy. |
|
|
Logistics and Sorting System |
High speed sorting equipment |
In express sorting lines and e-commerce parcel sorting machines, DS Cam Indexer controls the intermittent rotation of the sorting turntable, and works with a barcode scanner and push rod mechanism to accurately divert packages from different destinations to corresponding channels, adapting to sorting efficiency improvement of thousands of items per hour. |
The core requirement of these application scenarios is the combination of high-precision intermittent motion and precise positioning, and DS Cam Indexer perfectly adapts to the requirements of "high efficiency, stability, and precision" in automated production through the seamless fit between the cam and needle roller bearings, high rigidity structure, and self-locking characteristics, becoming the core component of intermittent motion control.
DS Cam Indexer, with its dual stop design, maintains the high rigidity and zero backlash advantages of the cam divider while nearly doubling its efficiency, making it an ideal choice for high-speed automation equipment. When selecting, special attention should be paid to the distribution of indexing angles and dynamic load capacity, and priority should be given to choosing the curved cam (high-speed) or cylindrical cam (heavy-duty) scheme.
