Through previous learning, I believe everyone has a general understanding and knowledge of the gearbox equipment. Do you know what the backlash means? Today, the editor will briefly introduce the meaning and calculation method of the backlash of the reducer:
The backlash of the reducer, also known as the return clearance, is generally defined in China as a small angular displacement at the input end when the output end is fixed and the input end rotates clockwise and counterclockwise, resulting in a rated torque of+-2%. This angular displacement is called the return clearance, and its unit is "minute", which is one sixtieth of one degree.
The rated power of a universal reducer is generally calculated and determined based on the use (operating condition) coefficient KA=1 (the motor or turbine is the prime mover and the working load is stable, working for 3-10 hours per day, starting frequency ≤ 5 times per hour, and allowing the starting torque to be twice the working torque), contact strength coefficient SH ≈ 1, and the failure probability of a single pair of gears ≈ 1%.
This product is a transmission device commonly used for low-speed and high torque applications. It reduces the speed of an electric motor, internal combustion engine, or other high-speed power by meshing a gear with fewer teeth on the input shaft with a large gear on the output shaft. Even ordinary reducers have several pairs of gears with the same principle to achieve the desired reduction effect, and the ratio of the number of teeth between the large and small gears is the transmission ratio.
The above is all the content that the editor has compiled today about the meaning and calculation of backlash in reducers. We hope it can be helpful for everyone's future use and understanding of the product!
