Reducer is a wide range of models, different types have different uses. Reducer is a wide variety, according to the type of transmission can be divided into gear reducer, worm reducer and planetary gear reducer; According to the different transmission series can be divided into single-stage and multi-stage reducer; According to the gear shape can be divided into cylindrical gear reducer, bevel gear reducer and conical-cylindrical gear reducer, according to the layout of the transmission can be divided into expansion type, shunt and coaxial reducer.

Characteristics of Reducer

1, the main characteristics of worm gear reducer is the reverse self-locking function, can have a larger deceleration ratio, the input shaft and output shaft is not on the same axis, also not on the same plane. But the general volume is larger, the transmission efficiency is not high, the precision is not high.

2, harmonic transmission of the harmonic reducer is the use of flexible components controllable elastic deformation to transfer movement and power, small size, high precision, Reducer but the disadvantage is the flexible wheel life is limited, not withstanding impact, rigidity and metal parts is poor. The input speed cannot be too high.

3, planetary reducer its advantages are relatively compact structure, small return clearance, high precision, long service life, rated output torque can do a great deal. But the price is slightly higher. 4. The gear reducer has the characteristics of small volume and large transmission torque.

5, gear reducer in the modular system based on the design and manufacture, there are very many motor combination, installation form and structural scheme, the transmission ratio is detailed, Reducer to meet different operating conditions, to achieve mechatronics. Gear Reducer has high transmission efficiency, low energy consumption and superior performance.

6, cycloid needle wheel reducer is a cycloid gear meshing planetary Transmission principle of transmission model, is an ideal transmission device, Reducer with many advantages, widely used, and can be operated.

The reducer is mainly composed of transmission parts (gears or worms), shafts, bearings, boxes and accessories. Its basic structure has three parts:

1. Gear, shaft and bearing combination

Pinion and shaft into one, called the gear shaft, this structure for the gear diameter and the diameter of the shaft is not related to the case, Reducer if the diameter of the shaft is D, gear tooth root circle diameter of DF, then when df-d鈮6~7mn, should use this structure. When DF-D>6~7MN is used, the gear and shaft are separated into two parts, such as low-speed shafts and large gears. At this point the gear and the axis of the circumferential fixed flat key joints, shaft parts using the shaft shoulder, sleeve and bearing cover for axial fixed. Deep groove ball bearings are used in both axes. This combination is used to withstand radial loads and minor axial loads. Reducer When the axial load is large, the combined structure of angular contact ball bearing, tapered roller bearing or deep groove ball bearing and thrust bearing should be adopted. The bearings are lubricated with a thin oil that is splashed when the gears are rotated. The lubricating oil in the tank seat is splashed into the inner wall of the lid by the rotating gear, and flows into the bearing through the guide oil trough after the inner wall is poured into the box-side groove. When the oil-immersed gear circumference speed 蠀鈮2m/s, should use lubricating grease lubrication bearings, Reducer in order to avoid the possibility of splashing dilute oil washed off the grease, can be separated by the oil retaining ring. In order to prevent the loss of lubricating oil and the outside dust into the box, the bearing end cover and the outer extension shaft are fitted with a sealing element.
