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.

The DC Gear motor , consisting of a DC electric motor and a gearbox, is at the heart of several electrical and electronic applications. ZHAOWEI have been designing and developing such high quality mini DC gear motors in an easy-to-mount package for a range of products and equipment. Our miniature gear motor work smoothly and efficiently, supporting these electrical and electronic applications. These geared motors have reduction gear trains capable of providing high torque at relatively low shaft speed or revolutions per minute (RPM).  ZHAOWEI DC geared motors reduce the complexity and cost of designing and constructing applications such as industrial equipment, actuators, medical tools, and robotics. ZHAOWEI has engineered a range of planetary and spur gear motors (also known as mini-geared motors and micro-geared motors) suitable for many future and existing applications. The main characteristics of these gear motors are miniature form factors, offering significant strength

Note for use of gear reducer

-
Principle of gear reducer :  A gear reducer is a speed converter that uses gears to reduce the number of revolutions of a motor to a desired number of revolutions and obtain a power transmission mechanism with a large torque. The role of gear reducer: Gear reducer is a common power transmission mechanism, which is used in many ships, automobiles, textile machines, printing and dyeing equipment, metallurgical equipment, cranes and other mechanical equipment. Gear reducer is a relatively precise machine. The purpose of using it is to reduce the speed and increase the torque. Note for gear reducer: 1. When using a gear reducer, it must be operated reasonably, and it cannot be used beyond its tolerance, nor can it exceed the rated torque and speed of the gear reducer. 2. It is necessary to maintain the ventilation and cleanliness of the gear reducer's use environment, and do the heat dissipation work of the machine daily to avoid affecting its performance. 3. The gear reducer
