Transmission structure of electric push rod

Abstract

The invention relates to the technical field of electric push rods, in particular to a transmission structure of an electric push rod. The transmission structure comprises a transmission shell consisting of a front cover and a rear cover, and an accommodating cavity is formed in the transmission shell; and the transmission structure is characterized in that the front cover is rotationally connected with a screw rod, the transmission shell is rotationally connected with a rotating shaft perpendicular to the screw rod, one end of the rotating shaft extends out of the transmission shell, the rotating shaft is in linkage with the screw rod through a speed reduction bevel gear set, and a reinforcing support arranged on the rotating shaft in a sleeving mode is arranged on the outer wall of the transmission shell. The transmission structure has the following effects that the reinforcing support is arranged on the outer wall of the transmission shell, the supporting force of the reinforcing support can be improved, the possibility that the rotating shaft deviates in the radial direction is reduced, transmission abrasion is reduced when the rotating shaft drives the screw rod to rotate through the speed reduction bevel gear set, and therefore the service life of the electric push rod is prolonged.

Description

technical field [0001] The invention relates to the technical field of electric push rods, in particular to a transmission structure of electric push rods. Background technique [0002] The electric push rod is an electric drive device that converts the rotary motion of the motor into the linear reciprocating motion of the push rod. It can be used as an executive mechanism in various simple or complex processes to achieve remote control, centralized control or automatic control. Control, because of its advantages of good stability, high operation precision and fast response speed, has been widely used, and has been widely used in various electromechanical complete sets of equipment and its automatic control devices. [0003] Generally, a screw rod is provided on the electric push rod along its length direction, and a rotating shaft for driving the screw rod to rotate will be provided at the lower end of the electric push rod. One end of the rotating shaft will extend out of ...

AI Technical Summary

Problems solved by technology

[0004] However, in the process of installation and use, it is often necessary to disassemble the electric push rod and the motor for maintenance or to add lubricating oil, and in this process, the output shaft of the motor will inevitably contact and collide with one end of the rotating shaft, making the rotating shaft The impact force in the direction perpendicular to its axial direction causes the rotating shaft to shake in the radial direction. At this time, there is a gap between the screw and the screw during transmission, and the wear is large during transmission, and the service life of the electric push rod is greatly reduced.
