Bearing Built-in RV Reducers

Bearing Built-in RV Reducer integrates output support bearings directly into the reducer housing.The cycloidal reduction mechanism sits inside the same housing envelope. An input shaft drives two cycloidal disks against fixed ring pins. Output torque transfers through a pin shaft assembly.   “RV” typically stands for “reduction vehicle” or “robotic vehicle,” signifying Bearing Built-in RV Reducers’ use in applications where high torque and precision are important, such as in servo systems and robotic arms.

Mechanical system overview of TallMan Robotics Bearing Built-in RV Reducers

Bearing built-in RV reducers are cycloidal reduction units with integrated support bearings that carry radial and axial loads within the housing. The design combines a spur gear input stage and a cycloidal disc stage to achieve high reduction ratio and low backlash. Integrated cross roller or tapered bearings support the output flange or shaft, which enables direct mounting of loads without external bearing blocks.

FAQs about Bearing Built-in RV Reducers

What are the common bearing Types in RV Reducers:

Needle Roller Bearings: Compact, high radial load capacity for cycloidal disks and eccentric shafts.
Angular Contact Ball Bearings: Handle combined radial/axial loads on input/output shafts.
Tapered Roller Bearings: Used in output stages for heavy axial/radial loads.
Cylindrical Roller Bearings: Support radial loads in high-speed sections.

What bearing types integrate into this reducer?

Crossed roller bearings standard. Tapered roller bearings optional. Deep groove ball bearings for light loads only.

Does built-in bearing eliminate external bearing support?

Yes. Mount load directly to output flange. No need for separate bearing housing or pillow block.

How do we replace a worn built-in bearing?

Disassemble entire reducer. Press out old bearing. Press in new bearing. Requires factory tooling.

Can we lubricate the built-in bearing separately?

No. Bearing shares grease with cycloidal mechanism. One grease fitting lubricates both components.
