Heavy Duty Cam Indexer

Material Upgrade

The cam and output turret (indexing plate) are made of high-strength alloy steel (such as 40Cr, 20CrMnTi), which undergoes heat treatment processes such as quenching and carburizing to improve hardness (the surface hardness of the cam can reach HRC58-62) and wear resistance, extending its service life.

The frame and shell are cast with cast iron (such as HT300) or cast steel as a whole to enhance overall rigidity and reduce deformation during operation.

Structural reinforcement

The cam profile design is thicker and has a larger contact area, reducing unit area pressure and avoiding cam wear or deformation under heavy loads.

The output shaft diameter is thickened (usually ≥ 50mm) and supported by multiple sets of high-precision bearings (such as tapered roller bearings and cylindrical roller bearings) to enhance its resistance to radial and axial loads.

The connection between the input shaft and the cam is rigidly fixed using keyways, expansion sleeves, or high-strength bolts to ensure that power transmission does not slip.

Sealing and Protection

Adopting multiple sealing structures (such as skeleton oil seals, O-rings) to prevent dust, oil stains, coolant, etc. from entering the interior, suitable for industrial environments with high dust, humidity, or oil stains (such as metal processing and heavy-duty assembly workshops).

Ultra high load-bearing capacity

Radial loads can reach hundreds of kilograms (such as workbench loads with a diameter of 1-3 meters), and axial loads can reach tens of kilograms, which can stably drive heavy workpieces or large turntables.

The peak torque can reach thousands of Newton meters, adapting to the instantaneous impact load during starting and braking.

High rigidity and vibration resistance

The overall structure has strong rigidity and minimal deformation during operation (≤ 0.01mm). Even in high-speed intermittent motion (input speed can reach 300-600rpm), it can maintain stability and reduce the impact of vibration on machining accuracy.

Long lifespan and low maintenance

The precision machined cam and roller (needle roller bearing or roller bearing) are lubricated with grease, with low friction coefficient and minimal wear. The design life can reach more than 10000 hours, and daily maintenance only requires regular replenishment of lubricating grease.

Wide working condition adaptability

It can work stably in harsh environments such as high temperature (-10 ℃~80 ℃), dust, and oil pollution, and is suitable for heavy industrial production scenarios.

Heavy duty assembly and processing equipment

The automated assembly line for automotive chassis and engine cylinder blocks drives large rotating workbenches (with a diameter of 2-5 meters) to complete processes such as bolt tightening, pressing, and inspection, carrying a weight of tens to hundreds of kilograms per single workpiece.

The heavy-duty machine tool indexing worktable, such as the multi-faceted machining mechanism of large milling and boring machines, drives the workpiece to intermittently rotate to achieve multi angle machining and withstand the large torque during the cutting process.

Heavy Material Handling and Sorting

Large logistics sorting turntables (such as container/heavy cargo sorting equipment in ports and warehouses) achieve intermittent reversing or positioning through dividers, and cooperate with robotic arms to complete the transfer of heavy-duty materials.

Automated processing lines for metal sheets and stone, such as cutting, polishing, and drilling, drive the worktable to intermittently feed and carry the weight of heavy sheets.

Heavy duty packaging and forming equipment

The fully automatic packaging machine for large cardboard boxes and wooden crates drives heavy-duty conveyor belts or turntables to complete material positioning, packaging, and palletizing, adapting to intermittent transmission of large-sized and heavy-duty packaging.

The forming equipment for concrete products and pipes controls the intermittent movement of molds or conveying mechanisms to withstand pressure loads during the forming process.

Special industrial equipment

The auxiliary equipment for rolling mills in the metallurgical industry, such as steel plate positioning and flipping mechanisms, achieves intermittent action through dividers to adapt to high temperature and dust environments.

The rotating mechanism of large rotating stages and automated storage warehouses requires intermittent transmission with high stability and large load carrying capacity.
