Cam Driven Indexer is a high-precision mechanical transmission device that achieves intermittent rotation or linear motion through the meshing of the cam and the profile of the driven component. When the input shaft rotates continuously, the profile of the cam pushes the driven roller, causing the output shaft to produce intermittent indexing motion. During the stay, the special profile of Cam Driven Indexer maintains stable locking of the output shaft. The core function is to convert continuous input motion into controllable intermittent output motion, ensuring the accuracy and repeatability of the action. Widely used in fields such as automated production and precision manufacturing.
The operation of Cam Driven Indexer is based on the kinematic characteristics of the cam mechanism, and its core principle can be disassembled into the following key parts: cam, follower, and indexing positioning By designing the curve parameters of the cam profile (such as lift, lead angle, rest angle, etc.), the motion speed, acceleration, and rest time of the driven component can be accurately controlled to meet different working conditions.
According to its structure and motion form, Cam Driven Indexer can be divided into the following common types:
|
Cam Indexers |
Structure |
Features |
|
Disc Cam Indexer |
The cam is disc-shaped, and the follower is usually connected to the output shaft. The output shaft rotates intermittently through the rotation of the cam profile. |
Compact structure, high indexing accuracy (up to ± 30 arc seconds), strong load-bearing capacity, suitable for small and medium-sized intermittent transmission scenarios (such as automated assembly lines and packaging machinery). |
|
Cylindrical Cam Indexer |
The cam is cylindrical in shape, with the contour machined on the outer surface or inner hole of the cylinder. The driven part meshes with the cam groove through rollers and rotates with the cam to achieve intermittent motion of the output shaft. |
Smooth transmission, fast speed (maximum input speed up to 1500 RPM), capable of multi station indexing, commonly used in high-speed automation equipment such as bottle cap machines and electronic component assembly machines. |
|
Globoidal Cam Indexer |
The cam profile is curved and forms a spatial mesh with the rollers of the driven component. The output shaft can achieve intermittent rotation at large angles. |
Strong load-bearing capacity, impact resistance, long service life, suitable for heavy-duty load scenarios (such as machine tool indexing, metallurgical equipment). |
Cam Driven Indexer is the core component for achieving precise intermittent motion in industrial automation. Its performance directly affects the efficiency and product quality of the equipment. When selecting, it is necessary to consider the accuracy requirements, load size, and speed requirements of specific working conditions comprehensively.
