The rated power of the universal reducer is generally based on the use (working condition) coefficient KA=1 (the motor or steam turbine is the prime mover, the working machine has a stable load, and it works for 3 to 10 hours a day. The coefficients to be considered are generally considered in the design. It should be checked, and the manufacturer should submit it to the manufacturer if it exceeds it. Design, so users need to consider Wholesale Planetary gear reducer different correction factors according to their requirements when selecting, and the factory should mark the nameplate according to the actual selected motor power (not the rated power of the reducer). According to mechanical power or torque to select specifications (strength check), the biggest difference between the design and selection methods of general reducer and special reducer is that the former is applicable to various industries, but the reduction can only be carried out according to a specific working condition. Thermal balance check, the allowable thermal power value of the universal reducer is under specific working conditions (general ambient temperature 20\u2103, 100% per hour, continuous operation, power utilization 100%), according to the maximum allowable lubricating oil The equilibrium temperature (generally 85\u00b0C) is determined. The universal reducer often has to limit the maximum radial load allowed by the middle part of the input shaft and output shaft extension. Check the radial load borne by the shaft extension. The latter is designed according to the user's special conditions. The number of starts per hour is \u2264 5 times.\ufeffThe size of the reducer should meet the conditions of strength, thermal balance, and radial load on the shaft extension. 2 times the working torque), the contact strength safety factor SH\u22481, the failure probability of a single pair of gears\u22481%, and other conditions are calculated and determined. Requirements such as thickening the shaft diameter and increasing the bearing. When selecting, it is only necessary to meet the use power of less than or equal to the rated power of the reducer, and the method is relatively simple.
