Hengyu Guoqiang-speed reducer

First of all, we should know what is transmission efficiency. Transmission efficiency of gear reducer usually refers to the ratio of output power (or output torque) to rated input power (or input torque multiplied by transmission ratio) when reaching rated input power (or input torque) at rated input speed. If it is necessary to obtain accurate transmission efficiency of gear reducer, it should be measured on a special test bench. According to the way of gear transmission, assuming that the gear is a rigid body without deformation, the efficiency of gear transmission will not be lost. But in reality, the gear can not be a rigid body. No matter how hard the gear is, it will produce a certain deformation when it is engaged. When the deformation occurs, it will cause a strong loss. This is one of the reasons for the loss of transmission efficiency. Moreover, when the gear is manufactured, it is impossible to achieve the accuracy of the theoretical value, and there must be errors. This kind of subtle error, When the gears are meshing, sliding friction will occur, and the friction needs extra work, which is the second reason for the loss of transmission efficiency. However, the transmission efficiency of gear reducers can be regarded as the best among gear reducers. Generally, the transmission efficiency of gear reducers is more than 90%. The transmission efficiency of well-known brand gear reducers of large factories can reach more than 95%. The transmission efficiency of cycloidal pin reducers is generally 90%. In contrast, the transmission efficiency of worm gear reducers is the lowest, generally only 75%, It can be seen that the transmission efficiency also has a great relationship with the transmission mode of the reducer. The gear reducer is driven through gear meshing, with multiple gears meshing, small contact surface and low friction coefficient, so it is not easy to lose the transmission efficiency. The worm gear reducer is driven by the friction between worm and worm gear, which has large friction coefficient and more transmission efficiency loss.
In order to improve the transmission efficiency of gear reducer, there are two key directions. One is to improve the hardness of the gear. The smaller the deformation of the gear is, the smaller the transmission efficiency will be lost; The second is to improve the manufacturing accuracy of the gear. The higher the accuracy of the gear, the smaller the sliding friction coefficient of the gear during meshing, and the higher the transmission efficiency.

The gear reducer produced by Yongkun motor has been moving in these two directions, constantly improving technology and updating equipment, including the fully automatic gear feed machine imported from Germany, to ensure the manufacturing accuracy of gear, and continuously improve the hardness level in gear material selection, so as to continuously improve the transmission efficiency of gear reducer. The transmission efficiency of Yongkun motor's gear reducer is not the best in the industry, but we can guarantee that the transmission efficiency of our gear reducer can reach more than 95%.
