What are Roller Gear Indexers
The roller gear indexer is a high-precision mechanical indexing device independently developed and produced by Hansheng Automation. It is designed for automated production lines and realizes intermittent motion control through the precise meshing of rollers and gears. Compared with traditional worm gear indexers, it can maintain positioning accuracy without brakes and is widely used in precision assembly, automated processing and other scenarios with strict requirements on indexing accuracy.
Products Core advantages
Micron-level indexing accuracy
The indexing accuracy can reach ±30 arc seconds, and the repeated positioning error is ≤15 arc seconds, which meets the micron-level processing requirements of precision electronics, medical equipment and other industries.
Adaptability to heavy-duty working conditions
Output shaft load:
The radial load is allowed to be 700kgf, which can support large-tonnage turntables or multi-station modules;
The axial thrust is allowed to be 560kgf, which is suitable for heavy-duty intermittent motion in the vertical direction (such as automotive parts assembly lines).
Input shaft load:
It can withstand axial thrust of 480kgf and repeated bending force of 415kgf, and can match high-torque servo motors to calmly deal with complex load impacts (such as instantaneous torque changes in automated welding equipment).
Maintenance-free long-life design
The structure adopts a sealed lifetime lubrication structure to prevent the intrusion of external impurities; the contact surface between the roller and the gear is hardened (surface hardness HRC58-62), and the wear rate is reduced by 60%. Under rated load (such as output shaft radial ≤700kgf, axial ≤560kgf), the service life exceeds 10,000 hours (about 1.2 years of continuous operation), which is 50% longer than the life of traditional worm indexers.
Brake-free high-efficiency transmission
The maximum repetitive torque of the input shaft reaches 40kgf·m, and with the gear meshing self-locking principle (no brake required), it supports high-speed indexing above 300rpm, and is suitable for high-frequency intermittent motion scenarios such as food packaging (such as high-speed canning machines) and electronic assembly (such as LED light board plug-in lines).

FAQ
Q: Selection misunderstanding: What happens if you only look at the load and ignore the torque?
A: If the input shaft torque (C5=40kgf・m) is insufficient, it will cause the index to jam (the servo motor reports "overload fault"). For example: driving a 100kg turntable (radius 0.5m), the load torque = 100×0.5=50kgf・m ＞ C5=40kgf・m, overload 25%, triggering insufficient safety factor (Note2 is safety factor 2, the design load should be 80kgf・m), and the life is directly shortened by 50%.
The correct approach is to calculate the static load torque + dynamic inertia torque (acceleration × moment of inertia) at the same time, and reserve 20% torque redundancy (if 50kgf・m is actually required, select a 60kgf・m motor).
Q: Maintenance-free ≠ zero maintenance! How to maintain in extreme working conditions?
A: In normal scenarios, when the temperature is -10~60℃ and the dust is ≤1mg/m³, the seal lubrication is maintenance-free for life.
In extreme scenarios (such as foundry workshops, dust ≥5mg/m³), the seal wear needs to be checked every 6 months (not specified in the parameter table, but derived based on the seal design), and replaced when the wear is >1mm; and a dust cover is installed to prevent the roller wear from causing the accuracy to deteriorate from ±30 arc seconds to ±60 arc seconds (affecting precision machining).
Q: How to quickly troubleshoot the sudden drop in accuracy during operation?
A: Three-step troubleshooting method:
① Check the load: whether it exceeds the rated value (radial > 700kgf / axial > 560kgf) → overload causes gear deformation;
② Check the installation: whether the coaxiality exceeds the standard → vibration makes the roller meshing clearance larger (accuracy from ±30 to ±60 arc seconds);
③ Check the environment: whether dust invades → roller wear (can be judged by "listening to the sound": normal is a smooth meshing sound, and there is a "rustling sound" after wear).
