How To Evaluate The Quality Level Of Speed Reducers,Gearboxes?
1.Select specifications according to mechanical power or torque (strength check)
The biggest difference between the general reducer and the special reducer design and selection method is that the former is applicable to various industries, but the reduction can only be designed according to a specific working condition, so users need to consider different correction factors according to their requirements when selecting , The factory should display the nameplate according to the actual selected motor power (not the rated power of the reducer); the latter is designed according to the user’s special conditions, and the coefficients for consideration are generally considered in the design. When selecting, as long as the use power is less than or equal to the deceleration The rated power of the device is sufficient, and the method is relatively simple.
2. Thermal balance check
The allowable thermal power value of the universal reducer is based on the maximum allowable equilibrium temperature of the lubricating oil (generally 85 ℃) definite. When the conditions are different, the corresponding coefficients (sometimes integrated into a coefficient) are used for correction.
3. Check the radial load on the shaft extension
General-purpose reducers often have to limit the maximum radial load allowed by the middle part of the input shaft and output shaft extension, which should be checked. When exceeding, the manufacturer should ask the manufacturer to increase the shaft diameter and increase the bearing.
4.Quality Evaluation
(1) The history of brand development.
(2) For mature serialized products, whether all classifications are very detailed.
(3) Noise. Can best reflect.
(4)The volume and size of the box. Compact design, comparison of imported reducers.
(5) Don’t consider the hardness of the tooth surface, the material of the parts, and the China ones.
(6) Oil leakage performance. This aspect of China and imported is more obvious.
(7) power, service factor.
