Shenzhen ZHAOWEI Machinery & Electronics Co., Ltd was established in 1997, which is State High-Tech enterprise for gear transmission design and manufacturing. Our DC motors are mainly related to automotive components, industrial equipment, smart home, medical equipment and standardized gear box, providing services and solutions for the world's intelligent driving. Small planetary gear box is widely used in mechanical transmission as an important part. For a pair of meshing gears, because there is inevitably a pitch, tooth shape error, in operation process will meshing impact and corresponding to the gear mesh frequency noise, between tooth surfaces due to the relative sliding and friction noise. Because of the gear is basic parts of gear box, reduce gear noise of gear box noise control is very necessary. Generally speaking, noise of the gear system mainly the following aspects: 1.Other aspects of the input torque. Load torque fluctuations, shaft torsional vibration,...

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 visco...
