Reducer in the prime mover and working machine or between the actuator to match the speed and transfer torque, reducer is a relatively precise machinery, the use of which is to reduce the speed of the Shanghai reducer worm reducer and planetary gear reducer;
according to the number of transmission stages can be divided into single-stage and multi-stage reducer plant wheel shape can be divided into cylindrical gear reducer, bevel gear reducer and conical - cylindrical tooth lead wheel reducer; according to the form of transmission arrangement can be divided into spreading type and shunt type and the same into the shaft type reducer. Reducer and conical - cylindrical gear reducer; according to the arrangement of the transmission can be divided into the form of unfolding, shunt type and the same into the shaft type reducer.
Reducer is a kind of enclosed in a rigid shell gear drive, worm drive, gear-worm drive composed of independent parts, often used as a prime mover and the working machine between the deceleration transmission device. Between the prime mover and the working machine or actuator to match the rotational speed and transfer torque, in the modern machinery is very widely used.
Expanded Information:
Example of reducer: cycloidal reducer
Features:
1, high speed ratio and high efficiency single-stage transmission, you can achieve a reduction ratio of 1:87, the efficiency of more than 90%, if the multi-stage transmission, the reduction ratio is greater.
2, compact structure and small size due to the use of planetary transmission principle, the input shaft output shaft in the same axis, so that its models to obtain the smallest possible size.
3, smooth operation and low noise cycloid needle tooth meshing teeth, overlap coefficient is large as well as the mechanism with the balance of the machine, so that the vibration and voice is limited to a minimum.
4, the use of reliable, long life because the main parts of the use of high-carbon chrome steel materials, quenched (HRC58 ~ 62) to obtain high strength, and, part of the transmission contact with the use of rolling friction, so durable long life.
