Speed reducer worm gear box NMRV075

Feature of worm reducer gearbox:
1) High quality aluminum alloy die cast Large output torque gearbox
2) High accuracy worm gear and worm shaft
3) Less noise and lower temperature increase Safe, reliable, economical and durable
4) Easy mounting anc connection, high efficiency, Stable transmission, quiet operation
5) High heat-radiating efficiency, high carrying ability
6) Combination of two single-step worm gear speed reducers, meeting the requirements of super speed ratio.

The NMRV reducer is a new type of reducer, or RV reducer."NMRV" refers to the aluminum shell reducer, which is used to refer to the aluminum shell reducer as the "NMRV reducer".The main components are oil seal, oil plug, worm gear box, ball bearing, the output shaft, worm gear, worm, mechanical shaft, motor connection plate (flange), the output shaft cover screw, hex socket steamed corn-bread, double round keys, gaskets, etc.NMRV series reducer - Our NMRV reducers with single flange input, some flanged output or double shaft output.

Notice for ordering:

1) when ordering,please refer to the details of the products and tell us the exact type your need according to your requirements,like input speed,output torque,configuration,installation,etc:the installation position of the products in the order should accord with your actual needs,otherwise, it will result in oil leakage, which will impact the serving life of the products negatively.if there is special requirement to the installation position,please stress it and inform us.

2) to attain the excellent state of the variators, the common working speed should be chosen in the middle position,instead,it ismot appropriate to choose in the positions of min,or max.speed

3) if your requirements of worm gearbox or speed variator are different from shte standard products as in the catalogue,like:some portion that should be customized or mounted with special motors,please inform us in advance
