Problems solved by technology

[0002] At present, most of the motors used in electrical appliances such as pulverizers and wall breaking machines on the market have the function of deceleration and variable speed. However, most deceleration and variable speed motors generally have unreasonable structural design, which leads to poor coordination of mechanisms, unsmooth switching, and prone to accidents. Abnormal noise and vibration, serious damage to gears, etc.

Abstract

The invention discloses a novel deceleration and speed change motor, which comprises a motor rotation shaft, an output rotation shaft located right above the motor rotation shaft and a deceleration mechanism arranged at one side of the motor rotation shaft and the output rotation shaft, wherein a switching mechanism capable of shifting along the axis direction of the motor rotation shaft is arranged between the motor rotation shaft and the output rotation shaft; and through shifting, the switching mechanism enables the motor rotation shaft to be directly connected with the output rotation shaft or enables the motor rotation shaft to be indirectly connected with the output rotation shaft through the deceleration mechanism. The motor rotation shaft can be directly connected with the output rotation shaft to be in a direct output state, the motor rotation shaft can also be indirectly connected with the output rotation shaft through the deceleration mechanism to be in a deceleration outputstate, switching between two different output states can be realized through arranging the switching mechanism capable of shifting along the axis direction, large and heavy parts such as the motor rotation shaft, the output rotation shaft or the deceleration mechanism do not need to be moved, the structure is reasonably designed, and the switching is convenient and smooth with no abnormal sounds.

Description

Technical field [0001] The invention relates to the field of variable speed motors, in particular to a new type of deceleration variable speed motor. Background technique [0002] At present, most of the motors used in electric appliances such as grinders and wall breakers on the market have the function of speed reduction and speed change. However, most speed reduction motors generally have unreasonable structural design, resulting in poor mechanism coordination, insufficient switching, and easy production Abnormal noise and jitter, or damage to gears in severe cases. Summary of the invention [0003] In order to solve the above problems, the purpose of the present invention is to provide a new type of decelerating variable speed motor with reasonable structural design, which can conveniently realize the variable speed switch between the direct output of the motor speed and the decelerated output, and the switching is smooth and without abnormal noise. [0004] The technical solut...
