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 gearbox of a wind turbine is one of the key components in wind power generation equipment, used to transfer the kinetic energy of the rotating wind turbine to the generator, thereby generating electrical energy. It is usually composed of multiple gears, which increase the speed of the wind turbine through precise transmission ratios and convert it into a speed suitable for the operation of the generator. Usually, the speed of the wind turbine is very low and far from the required speed for the generator to generate electricity. It must be achieved through the speed increasing effect of the gearbox gear pair, so the gearbox is also called a speed increasing gearbox.
JH series gear reducers for cement kilnsare involute cylindrical gear units with parallel shafts which has four reduction stages.This series has four basic structure including over 50 types.Thanks to the standardized,series and modulated design,the reducers can be manufactured according to standard or specific requirements at customers'choice with good reliabiity and maintenance.
The latest XB series gear reducers for roller presses includes totaly 33 models with transmission powerup to 4,000kW and a torque transmission capacity up to 5300KN.m.
According to different cement production lines with transmission power up to 8400kW and ratio from 35:1 to 80:1,we can match JS JST,JD(X)and MDH series central driving mil reducers to meet needs for various cement lines of daily output 2500-10,000 tons.
The variable pitch gear box is an important part of the fan variable pitch system, its main function is to increase the torque of the variable pitch motor on the variable pitch bearing, drive the blade to change the blade pitch Angle at different wind speeds, so that the blade is in the best state of absorbing wind energy, and can drive the blade feathering brake when the wind speed exceeds the cutting wind speed, so as to ensure the machine to run efficiently and smoothly.
The variable gear box transmission mechanism is composed of multiple planetary gear trains, usually 3 stages, and the planetary transmission form is NGW type.
