Test of gear bending fatigue limit based on up and down method The bending fatigue strength of gear is an important indicator for gear performance, it is a good approach to gain the bending strength in the light of the test procedure. The test of the single – tooth bending fatigue strength of 20CrMoH carburized gear is discussed. After a series of experiments, the result represents that it is more actual to determine the risk position with broken – line section method. It provides a new approach for evaluating the gear bending fatigue strength. Making full use of this theory, the gearbox can be improved in a certain level. With more than 20-year experience on gearbox and micro motor, Zhaowei has designed and produced tons of high-quality products.

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...

Gear deceleration motor is a new type of operation equipment, and this equipment can provide lower speed, greater torque, for our production and life has brought convenience. In order to save time and effort in installation, and to ensure the effect of use, we need to pay attention to the following five points when wiring, let's get to know it together. 1. Power input: The thick red wire on the gear reducer motor is the positive end of the power supply, the black wire is the negative end of the power supply, and the fine orange wire is the door lock. 2. Motor phase: Coarse yellow line is U, Coarse green line is V, Coarse blue line is W. 3. Signal input: Fine red line is + 5V power supply, Fine green is handle signal input, Fine black line is grounding line. 4. Machine Hall: Fine red line is + 5V power supply, fine black line is grounding line, fine yellow line is A, fine green line is B, fine blue line is C. 5. Sensor: Fine red line is + 5V power supply, fine black li...
