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. For more information: http://www.zwgearbox.com/LatestNews/Testofgearbendingfat_1.html
Fault analysis of gear reducer
The gear reducer is a power transmission mechanism that uses a gear speed converter to decelerate the number of revolutions of the motor to a desired number of revolutions and obtain a device with a large torque. The gear reducer is a relatively precise machine that is used to reduce the speed and increase the torque. To better understand your equipment, you should know where it is often faulty and how to repair it. The most common faults of gear reducers are tooth spalling, pitting, falling and broken teeth, especially at low speeds. Gears, falling blocks and broken teeth are the most frequent. According to the analysis, the position of the gear reducer of the gear reducer is generally asymmetrical, so that the gear shaft of the low speed large gear of the gear reducer is skewed, and the center line and the center line of the gear shaft of the two pinions meshing with it are not parallel, resulting in a low speed large gear. The gear teeth of the two pinions are reduced, most of ...
