NMRV reducer is a new type of reducer, which can also be called RV reducer. "NMRV" is a collective term, which refers to aluminum housing reducer, and it is customary to call aluminum housing reducer as "NMRV reducer" in the world. The main components are oil seal, oil plug, worm gear box, ball bearing, output shaft, worm gear, worm, output shaft, motor connection plate (flange), output shaft cover, hexagon socket head screw, double key, gasket, etc. One of the NMRV series reducers, BHADE reducers, some have a single flange input, some have a flange output or a double shaft output, etc. Nmrv-nrv worm gear reducer is one type of reduction gear box which consists of a worm pinion input, an output worm gear, and features a right angle output orientation. This type of reduction gear box is generally used to take a rated motor speed and produce a low speed output with higher torque value based on the reduction ratio. They often can solve space-saving problems because the nmrv-nrv worm gear reducers is one of the sleekest reduction gearboxes available due to the small diameter of its output gear Super reducer use high quality main material: aluminum, copper, iron material Be popular of its high quality and competitive price and prompt delivery in china and abroad The Basic model: NRV25, NRV30, NRV40, NRV50NRV63NRV75NRV90NRV110NRV130NRV150 NMRV25NMRV30NMRV40NMRV50NMRV63NMRV75NMRV90NMRV110NMRV130NMRV150

Reduction Ration : The bigger speed reduction ration, the lower running speed of output shaft. The speed reduction range for single stage worm gear reducers is 1/5~1/100. The reduction ration range for 2-stage worm gear reducers is 1/100~1/3600. Type : The standard types are marked with W.B. and K. Model numbers suffixed with an E represent direct drive models. Model numbers suffixed with H, such as BH and KH, represent 2-stage worm gear reducer which is normally an intrant-type reducer. Model : Defined by the center distance between shafts. The bigger the model number. The bigger the reducer structure.

Housing material is high density aluminium alloy ADC-12. Gear profile type ZK which efficiency up to 0.9. Other China made gear profile type is in ZA which efficiency up to 0.7 only. Hobbing tools for ZK profile are much expensive more than 10 times than ZA. Material of worm shaft is 40Cr (ASTM 5140). Others makers are using 45# steel which quality is poor while using it as worm shaft. Material of brass on worm wheel is ZQSnD10-1 (DIN GB-CuSn10/2.1051)(BS PB1) which other China makers are using ZQSND9-4 only. Bearings from FAG bearings China OEM makers. Synthetic lubrication oil of TAXAS brand. 100% running test before ex-factory.
