For the wear problem, the traditional solution of the enterprise is repairing after repair welding or brush plating, but both have certain drawbacks: the thermal stress generated by the repair welding high temperature cannot be completely eliminated, which may cause damage to the material and cause the parts to bend or break; Brush plating is limited by the thickness of the coating, and it is easy to peel off. The above two methods use metal to repair the metal, which can not change the "hard to hard" coordination relationship. Under the combined action of each force, it will still cause re-wear. For some large bearing enterprises, it is impossible to solve on-site, and it is necessary to rely on external repair. In the contemporary Western countries, the repair method of polymer composite materials is often used for the above problems, and the application has more comprehensive properties such as superior adhesion and excellent compressive strength. The application of polymer material repair can be free of disassembly and machining without the influence of repair welding thermal stress, and the thickness of the repair is not limited. At the same time, the metal material of the product does not have the concession, which can absorb the shock vibration of the equipment and avoid the wear again. It is possible, and greatly extends the service life of equipment components, saving a lot of downtime for the enterprise and creating huge economic value.

nhazi ọkwa:
When selecting the reducer, according to the selection conditions of the working machine, technical parameters, performance of the power machine, economy and other factors, compare the outer dimensions of different types and types of reducers, transmission efficiency, load capacity, quality, price, etc. Reducer.
The load state of the working machine connected with the reducer is complicated, and has a great influence on the reducer. It is an important factor in the selection and calculation of the reducer. The load state of the reducer is the load state of the working machine (slave), which is usually divided into three. Class: 1 - uniform load, 2 - medium impact load, 3 - strong impact load.
transmission:
A gear reducer is a type of transmission that increases the wear of its internal transmission as it works longer. So what aspects should we analyze the wear of the internal gear of the gear reducer? The losses in the gear unit (gear frame and reducer) in the gear reducer include the following three aspects:

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, nor on the same plane. However, the volume is generally large, the transmission efficiency is not high, and the accuracy is not high. The harmonic drive of the harmonic reducer is the elastic deformation controlled by the flexible element to transmit motion and power. The volume is small and the precision is high, but the disadvantage is that the flexible wheel has limited life and is not impact resistant. The rigidity is compared with the metal parts. difference. The input speed cannot be too high. The planetary reducer has the advantages of compact structure, small return clearance, high precision, long service life and large rated output torque. But the price is slightly more expensive. The gear reducer has the characteristics of small size and large transmission torque. The gear reducer is designed and manufactured on the basis of the modular combination system. There are many motor combinations, installation forms and structural schemes.

The cycloidal pinwheel reducer is a transmission type that adopts the principle of cycloidal pin gear meshing planetary transmission. It is an ideal transmission device with many advantages, wide application and forward and reverse operation.
The speed reducer plays a role of matching the rotational speed and transmitting torque between the prime mover and the working machine or the actuator, and is a relatively precise machine. The purpose of using it is to reduce the speed and increase the torque. It has a wide variety of models, different models, and different types of 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 different drive stages, they can be divided into single-stage and multi-stage reducers. According to the gear shape, they can be divided into cylindrical gears. , bevel gear reducer and cone-cylindrical gear reducer; according to the transmission arrangement can be divided into expansion, split and coaxial reducer.The reducer is generally used for transmission equipment with low speed and high torque. The motor, internal combustion engine or other high-speed power is driven by the gears with few teeth on the input shaft of the reducer to mesh the large gear on the output shaft to achieve the purpose of deceleration. The reducer will also have several pairs of identical principle gears to achieve the desired deceleration effect. The ratio of the number of teeth of the large and small gears is the transmission ratio.
