RV Series Worm Gear Speed Reducer

Product Description

The RV reducer consists of a front stage of a planet-gear speed reducer and a rear stage of a cycloidal pin gear speed reducer. The RV reducer has the advantages of compact structure, large transmission ratio, and transmission mechanism with a self-locking function under certain conditions. It is one of the most commonly used reducers, and it has low vibration, low noise and low energy consumption.

RV Reducer Features:

(1) Alarge transmission ratio range;

(2) The torsional stiffness is large, and the output mechanism is the planet carrier supported at both ends. The rigid disc with the left end of the planet carrier is output. The large disc is bolted with the working mechanism, and its torsional stiffness is much larger than that of the general cycloidal pinwheel. The output mechanism of the reducer. Under the rated torque, the elastic backlash is small;

(3) As long as the design is reasonable and the manufacturing assembly precision is guaranteed, high precision and small gap backlash can be obtained;

(4) High transmission efficiency;

(5) The volume when transmitting the same torque and power is small (or the bearing capacity per unit volume is large), the RV reducer uses three planetary gears for the first stage, especially the second stage, the cycloidal pin wheel is hard. The multi-tooth engagement of the tooth surface, which in turn determines that it can transmit large torque with a small volume, and in the structural design, the transmission mechanism is placed in the supporting main bearing of the planet carrier, so that the axial dimension is greatly reduced. All of the above factors greatly reduce the total volume of the transmission.

Worm Gear Speed Reducer summary:

Single Step Worm Gear Reducer

1.Made of Aluminum alloy die-casting box, good looking in appearance, compact in structure rust proofing on Surface and smallvolume to save mounting space.

2.Good radiating characteristic leads safe and high efficiency for using.

3.The strong capacity of loading and overload ensure stable transmission, make less vibration and noise.

4.Varies of connecting structure for power input and torque output meet different requirements; the design of box outline and theset of foot hole is apt to with high many kinds of mounting.

5.Besides big cases, no gap structure of box means a maintenance-free that is hermetically sealed. It prevents the lubricantfrom easily losing and going bad, and exchanging.

Double Step Worm Gear Reducer

1.It is combined by two single step reducers and has all the virtues of them. And you can get bigger ratio with it.

2.The models of25/30,25/40,30/40,30/50,30163,40/75,40/90,50/110,63/130,63/150, are in common use.

3.You can choose25,30,40,50,63,75,90,110,130,150 as combination units to combine according to the fact of your special needs.
