The reducer plays the role of matching speed and transmitting torque between the prime mover and the working machine or actuator. The reducer is a relatively precise machine. The purpose of using it is to reduce the speed and increase the torque. According to the different transmission series, it can be divided into single-stage and multi-stage reducers; according to the shape of the gear plant, it can be divided into cylindrical gear reducer, bevel gear reducer and cone-cylindrical tooth guide wheel reducer; according to the layout of the transmission It can be divided into expansion type, split type and co-axial type reducer. The reducer is an independent component composed of gear transmission, worm transmission, and gear-worm transmission enclosed in a rigid housing. It is often used as a reduction transmission device between the original moving part and the working machine. It plays the role of matching speed and transmitting torque between the prime mover and the working machine or the actuator, and is widely used in modern machinery.

1. installation method:

The correct installation, use and maintenance of the reducer is an important link to ensure the normal operation of mechanical equipment. Therefore, when you install the reducer, please be sure to strictly follow the following installation and use related matters, carefully assemble and use.

The first step is to confirm whether the motor and reducer are intact before installation, and strictly check whether the dimensions of each part connected to the motor and the reducer match. Here are the dimensions and matching tolerances of the positioning boss, input shaft and reducer groove of the motor.

The second step is to unscrew the screw on the dust hole on the outer side of the reducer flange, adjust the clamping ring to align its side hole with the dust hole, insert the hexagon socket and tighten it. After that, take away the motor shaft key.

The third step is to connect the motor with the reducer naturally. During connection, the concentricity of the output shaft of the reducer and the input shaft of the motor must be consistent, and the outer flanges of the two must be parallel. If the concentricity is inconsistent, it will cause the high-speed shaft of the reducer to break or the gear of the reducer to wear.

2. development trend:

1. High level and high performance. Cylindrical gears generally use carburizing, quenching, grinding, carrying capacity increased by more than 4 times, small size, light weight, low noise, high efficiency, high reliability.

2. Modular design. Basic parameters using priority number, size specifications neat, parts versatility and interchangeability, the series is easy to expand and pattern renovation, conducive to the organization of mass production and reduce costs.

3. Diversified types and many variant designs. Getting rid of the traditional single base installation method, adding a hollow shaft suspension, floating support base, motor and reducer integrated connection, multi-directional installation surface and other different types, expand the scope of use.

The main factors that 3. promote the improvement of the level of the reducer are:

① The theoretical knowledge is becoming more and more perfect and closer to reality (such as gear strength calculation method, modification technology, deformation calculation, optimization design method, smooth transition of tooth root, new structure, etc.).

The use of good materials, the general use of a variety of high-quality alloy steel forgings, materials and heat treatment quality control level.

The structural design is more reasonable.

The machining accuracy is improved to the ISO5-6 level.

⑤ bearing quality and life improved.

The quality of lubricating oil is improved.
