Problems solved by technology

However, the structure of the transmission in the above-mentioned way all needs to be sealed by a shaft seal to prevent internal lubricating oil from leaking
However, the shaft seal cannot achieve an absolute sealing effect, so that in harsh environments, the particles in the environment enter the speed reducer, reducing the performance and life of the speed reducer
In addition, high-speed rotation and high stress will inevitably occur in the speed reducer, which is bound to be accompanied by high temperature. High stress will easily damage the oil film, resulting in a sudden increase in friction, which also reduces the performance and life of the speed reducer.

Abstract

An accelerating and decelerating device comprises an input shaft, a transmission mechanism, an accelerating and decelerating mechanism and an output shaft, wherein the transmission mechanism is connected with the input shaft, the accelerating and decelerating mechanism is connected with the transmission mechanism, and the output shaft is connected with the accelerating and decelerating mechanism. The transmission mechanism comprises a transmission shaft, an inner magnetic part, a sealing cover, a mounting shell and an outer magnetic part, the inner magnetic part is arranged in the transmission shaft, the sealing cover sleeves the transmission shaft, the mounting shell movably sleeves the sealing cover, the outer magnetic part is arranged in the mounting shell, the outer magnetic part and the inner magnetic part are opposite, the magnetisms of the outer magnetic part and the inner magnetic part are inverse, the input shaft is fixed to the mounting shell, and the accelerating and decelerating mechanism is positioned on one side of the transmission shaft and the sealing cover far away from the input shaft and fixed to the sealing cover. The accelerating and decelerating device has high radiating, high dustproof and high lubrication functions, performances are further enhanced, and the service life is further prolonged.

Description

technical field [0001] The invention relates to a transmission device, in particular to a speed increasing and decelerating device capable of speeding up or decelerating. Background technique [0002] Speed ​​increasers or reducers are often used in the field of intelligent robots and automation to achieve motion transmission and speed change. The commonly used transmission mode of the speed reducer is transmitted by means of harmonics, gear sets, etc. However, in the structure of the transmission in the above-mentioned manner, the shaft seal needs to be used for sealing, so as to prevent the leakage of internal lubricating oil. However, the shaft seal cannot achieve an absolute sealing effect, so that in harsh environments, the particles in the environment enter the speed reducer, reducing the performance and life of the speed reducer. In addition, high-speed rotation and high stress will inevitably occur in the speed reducer, which is bound to be accompanied by high temp...
