Problems solved by technology

However, in this actuator structure, the stop sleeve is directly sleeved on the output shaft, so there is a large gap between the stop sleeve and the output shaft, and the stop sleeve will Shaking, generating noise, and causing the nut to move to the position against the stop sleeve, because the stop sleeve is skewed, the end face of the nut and the end face of the stop sleeve cannot be well abutted, affecting the nut and the stop sleeve Strength of

Abstract

The present invention provides an actuator and its transmission mechanism. The actuator includes a motor, an actuator and a transmission mechanism arranged between the motor and the actuator. The transmission mechanism includes a main body and an output shaft protruding from the main body. , the output shaft rotates under the drive of the motor, and the output shaft is provided with threads for driving the actuator to move axially along the output shaft, and the actuator further includes at least two arc-shaped A shaft sleeve and a stop sleeve, the at least two arc-shaped sleeves are arranged around the output shaft and spliced ​​to form an annular sleeve located between the main body and the actuator, the annular sleeve and the A gap fit is formed between the output shafts, and the stop sleeve is sleeved on the annular bushing and is interference fit with the annular bushing. The actuator of the invention has low noise and good strength.

Description

[Technical field] [0001] The present invention relates to an actuator and its transmission mechanism. 【Background technique】 [0002] The existing actuator includes a motor, a gearbox driven by a motor, and a gearbox, which are arranged in a stop sleeve close to one end of the gearbox of the gearbox, and a nut between the output shaft by a thread. When the output shaft is rotated by the gearbox, the nut moves straight on the output shaft to drive the load movement, such as adjusting the position of the car seat, the position of the headrest, the position of the steering wheel, and the like. However, in such an actuator structure, the stop sleeve is directly in the output shaft, so the stop sleeve and the output shaft have a large gap, and the stop sleeve will be stopped when the output shaft rotates. Shake, generate noise, and cause the nut when moving to the stop sleeve position, due to the stop sleeve skew, the end surface of the nut is not very resistant to the end surface of ...
