The assembly accuracy has a direct influence on the meshing condition and load-carrying capacity of gears.
The influence of lubrication mode on the efficiency of reducer The lubrication mode of gears is determined by the pitch speed of gears. Oil bath lubrication can be used when the pitch speed is not very high. The loss of stirring oil in oil bath lubrication is related to tooth width, gear circumference speed, oil immersion depth, oil viscosity and other factors. Generally speaking, the wider the gear, the deeper the oil immersion, the higher the oil viscosity, and the higher the gear speed, the greater the oil stirring loss. When the throttle speed is high, oil injection lubrication should be used as far as possible. The main loss of oil injection lubrication is the energy consumed by accelerating oil supply. It is related to the amount of oil supplied, the oil storage gap between meshing teeth and the oil viscosity. The curves of oil mixing loss with gear pitch velocity are given under different viscosity, top clearance and oil supply under oil injection lubrication.
The oil viscosity and the amount of oil supplied also have a great influence on the loss of stirring oil. Choosing lubricating oil with lower viscosity can reduce the loss of stirring oil. The greater the oil supply, the greater the loss of torque, but the smaller the oil supply, the less lubrication the gear may get, resulting in increased meshing loss. The assembly accuracy of the reducer mainly includes the assembly accuracy of the gear on the shaft and the assembly accuracy of the shaft on the bearing. The assembly accuracy has a direct impact on the meshing status and load-bearing capacity of the gear, and the assembly accuracy of the high-speed transmission gear has a greater impact on the efficiency. For the high-speed light-load reducer, because its power loss is mainly no-load loss, light bearing and thin oil lubrication should be considered. Minimize the geometric dimensions of gears and bearings to reduce the pitch speed. Reduce the oil supply to reduce the power loss caused by the acceleration of lubricating oil.
