Abstract

The invention discloses a linear actuator. The linear actuator comprises a speed reducer housing, wherein a motor is arranged at one end of the speed reducer housing, and a secondary planet carrier isarranged at the other end of the speed reducer housing; a motor base fixedly connected with the motor is arranged at the position, close to one end of the motor, of the interior of the speed reducerhousing, and the motor base and the speed reducer housing are relatively static; a planet wheel set matched with the secondary planet carrier is also arranged in the speed reducer housing; and the inner end face of the motor base is provided with a first sealing ring adapted to the planet wheel set. The sealing effect of components of the linear actuator is good, there is no leakage of lubricatinggrease or dust particles in the working process of the linear actuator, and it is fully ensured that the linear actuator can run stably.

Description

technical field [0001] The invention relates to the technical field of supporting components of power transmission equipment, in particular to a linear drive. Background technique [0002] In the current technical field of power equipment, the linear drive gearbox is usually a planetary gearbox, which relies on gear transmission inside, and needs lubricating oil or grease to lubricate the main transmission parts such as the gear; the transmission process of the gear will cause gear wear and produce micro Dust particles, due to the limitation of the structure of the existing linear drive itself, the leakage of lubricating grease or dust particles is very easy to occur during the operation of the equipment. If the grease or dust particles leak to the outside of the equipment, especially the leakage And polluting the side where the motor is located will seriously affect the performance of other transmission components and adversely affect the overall normal operation of the lin...
