Overview
Hollow-centre RV reducer with a large through-bore for cables, hoses and shafts. Usually driven by an external spur gear for a combined overall ratio.
The RV stage is the same two-stage spur and cycloid design as the E series, arranged around a hollow centre so services can run straight through the joint.
Typical uses: robot base (J1) and wrist joints with internal cabling, two-axis welding positioners, large rotary and indexing tables, radar, antenna and turret drives.

35.61:1 is the ratio of the reducer alone, without the input spur gear. The overall ratio depends on the spur gear: tell us your motor and the output speed you need and we size it.
Ordering
Order code TRV-320C. Price ₹3,49,305 per unit, ex-works Rajkot, excluding GST and freight. MOQ 1 piece; ask for volume pricing from 10 pieces. Send your motor model and we confirm the input gear or adapter flange you need.
Ratings are typical values from manufacturer tests and are for guidance only. Real performance depends on installation, load, lubrication and environment; confirm your selection with Torqtron engineering. The photograph is representative of the series.

Send your motor detailsQuestions about the TRV-320C
Is the price the same for every ratio?
The TRV-320C costs ₹3,49,305 per unit, ex-works Rajkot, excluding GST and freight. MOQ is 1 piece; ask for volume pricing from 10 pieces.
Is the input spur gear included in the ratio?
No. 35.61:1 is the reducer alone. The external spur gear adds its own ratio; tell us your motor and the output speed you need and we size the gear pair.
Which motor can drive the TRV-320C?
Send us the motor model, flange and shaft size. We machine the input gear and, if needed, an adapter flange so the motor bolts straight on.
