Simple Analysis Of Factors Affecting Transmission Efficiency Of Gear Type Slewing Drive

Friction loss is the decisive factor for gear transmission efficiency of spur gear slewing drive, when the friction coefficient continues to increase, the transmission efficiency of gears continues to decline, and efficiency and friction are inseparable. The factors that affect the coefficient of friction are: the roughness of the tooth surface, the lubrication condition and the error of the center distance. Next, the engineers of Unique Transmission will briefly analyze the three factors that affect the transmission efficiency of the slewing drive.

Roughness of tooth surface:

In gear transmissions such as spur gear slewing drives, the gears will vibrate and impact, and this vibration and impact will affect the mechanical properties and life of the gear. The roughness of the gear is affected by the processing method of the gear. The tooth surface roughness of the grinding tooth is better, the tooth surface of the gear shaping is second, and the tooth surface of the hobbing is relatively rough. The smaller roughness of the tooth surface, the smaller impact of the gear on the vibration, the smaller noise caused, and the smaller friction loss. At the same time, the temperature rise of the gear due to frictional heat generation is avoided.

Lubricating:

In gear transmission, lubrication can reduce the coefficient of friction. Lubrication can be divided into lubrication methods and lubrication properties. Gear lubricants have the functions of reducing friction, dissipating heat, preventing rust, reducing vibration, impact and noise and removing dirt.

Center distance:

In gear transmission, the change of center distance directly causes the pitch circle to not coincide in the position of gear transmission. For example, the spur gear slewing drive should appropriately increase the center distance, reduced friction, can improve the transmission efficiency of gears, at the same time, the backlash between the teeth is also increased, which avoids the situation that the tooth backlash is too small and gets stuck due to the deformation caused by the sudden increase of the load or the temperature increase in the gear transmission.
