definition:

The reducer is an independent component consisting of gear transmission, worm transmission, and gear-worm transmission enclosed in a rigid shell. It is often used as a reduction transmission device between the original moving parts and the working machine. The function of the reducer is to reduce the speed and increase the torque.

Introduction:

Reducers are generally used for low-speed and high-torque transmission equipment. The power of an electric motor, internal combustion engine or other high-speed operation is achieved through the gear with a small number of teeth on the input shaft of the reducer and the large gear on the output shaft to achieve the purpose of deceleration. Ordinary The reducer will also have several pairs of gears with the same principle to achieve the ideal reduction effect. The ratio of the number of teeth of the large and small gears is the transmission ratio.

Classification:

The reducer plays the role of matching speed and transmitting torque between the prime mover and the working machine or actuator. It is a relatively precise machine. The purpose of using it is to reduce the speed and increase the torque. It comes in many types, with different models, and different types have different uses. There are many types of reducers. According to the transmission type, they can be divided into gear reducers, worm reducers and planetary gear reducers; according to the number of transmission stages, they can be divided into single-stage and multi-stage reducers; according to the gear shape, they can be divided into cylindrical gear reduction reducer, bevel gear reducer and bevel-cylindrical gear reducer; according to the transmission layout, it can be divided into expansion reducer, split flow reducer and coaxial reducer.

Features:

The main feature of the worm gear reducer is that it has a reverse self-locking function and can have a large reduction ratio. The input shaft and the output shaft are not on the same axis or on the same plane. However, they are generally large in size, low in transmission efficiency, and low in precision.

The harmonic transmission of the harmonic reducer uses the controllable elastic deformation of flexible components to transmit motion and power. It is small in size and has high precision. However, its disadvantages are that the flexspline has limited life, is not resistant to impact, and is less rigid than metal parts. Difference. The input speed cannot be too high.

The advantages of planetary reducer are relatively compact structure, small return clearance, high precision, long service life, and the rated output torque can be very large. But the price is slightly expensive. The gear reducer has the characteristics of small size and large transmission torque.

Gear reducers are designed and manufactured on the basis of a modular combination system. There are many motor combinations, installation forms and structural solutions. The transmission ratios are finely graded to meet different operating conditions and achieve electromechanical integration. The gear reducer has high transmission efficiency, low energy consumption and superior performance.

The cycloidal pinwheel reducer is a transmission model that adopts the principle of cycloidal pin tooth meshing planetary transmission. It is an ideal transmission device with many advantages, wide range of uses, and can operate in forward and reverse directions.

effect:

1. Reduce the speed and increase the output torque at the same time. The torque output ratio is based on the motor output multiplied by the reduction ratio, but be careful not to exceed the rated torque of the reducer;

2. Deceleration also reduces the inertia of the load, and the reduction in inertia is the square of the reduction ratio.

Application areas:

Reducer is a mechanical transmission device in many fields of the national economy. The product categories involved in the industry include various types of gear reducers, planetary gear reducers and worm reducers, as well as various special transmission devices, such as speed increasing devices and speed regulators. devices, and various types of composite transmission devices including flexible transmission devices. The product and service fields involve metallurgy, non-ferrous metals, coal, building materials, shipbuilding, water conservancy, electric power, engineering machinery and petrochemical industries.
