Abstract

The invention discloses a lead screw assembly device. The lead screw assembly device is applied to an electric push rod, and comprises a lead screw, a bearing and a helical gear. The bearing is arranged at the tail end of the lead screw. The helical gear is arranged on the lead screw in a flat filament cooperation mode and tightly presses the bearing in an abutting mode. Due to the fact that a connecting portion and a connecting hole can achieve the surface contact, the lead screw assembly device can have the beneficial effects that the reliability of the cooperation is improved, and the impact sound generated in the forward and reverse rotation process is lowered and even eliminated.

Description

Technical field [0001] The invention relates to mechanical equipment, in particular to a screw assembly device applied to an electric push rod. Background technique [0002] Electric actuator is a universal auxiliary drive device, which can be widely used in electric power, machinery, metallurgy, transportation, mining, petroleum, chemical industry, heavy lifting, transportation, construction, grain and feed processing and other industries. It has reliable performance, sensitive action, and operation Stable, same push-pull force, good environmental adaptability, etc. [0003] Electric push rod is an electric drive device that converts the rotation of the motor into the linear reciprocating motion of the push rod. It can be used as an executive machine in a variety of simple or complex technological processes to achieve remote control, centralized control or Automatic control. [0004] The gear of the prior art electric push rod is connected with the screw rod. It is necessary to pe...
