  • Product Details
  • Inquiry

Hollow RV reducers, also known as hollow type RV gear reducers, are specialized gearboxes commonly used in various applications due to their efficient design and high performance. They feature a hollow bore that allows for the routing of wires, pipes, and shafts through the center, facilitating flexible design and saving space. 

This bore RV Reducer contains a central through-bore that allows cables, shafts, or media lines to pass axially through the unit. The cycloidal reduction mechanism surrounds the hollow passage. An eccentric cam drives two cycloidal disks against fixed ring pins.

Engineering specification overview of TallMan Robotics Hollow RV Reducers

Hollow RV reducers are precision cycloidal gear units with a central bore that allows shaft or cable passage through the gearbox body. The design uses a two-stage reduction mechanism, including a spur gear input stage and a cycloidal disc stage, to deliver high torque with low backlash. Hollow bore gearboxes from TallMan Robotics include 10C,27C,50C,100C,120C,200C,320C.

FAQs about Hollow RV Reducers

Does the hollow bore need a protective liner?

Yes for sharp cables. Install nylon liner. Prevents cable abrasion against steel bore surface.

Can we run two separate cables through the bore of these Hollow RV Reducers?

Yes. Use a cable separator. Split bore into two channels. This prevents tangling during rotation.

Can we pass compressed air through the bore?

Yes with rotary union. Install union at fixed end. Connect rotating union to hollow shaft.

What bearings support the hollow output of the RV Reducer?

Crossed roller bearings standard. For higher speeds, use angular contact bearings in tandem.

How do we clean debris from the hollow bore?

Use compressed air blow gun. Insert through bore end. Do not use solvents that dissolve grease seals.

Can we retrofit a solid reducer to Hollow RV Gearboxes?

No. Housing design differs completely. Replace entire unit. Measure required bore size before ordering.
