Problems solved by technology

[0009] In order to solve the above-mentioned problems, an object of the present invention is to provide a small-sized motor with a reduction mechanism and a motor for an electric seat with a reduction mechanism, the above-mentioned motor has a simple structure and can prevent teeth from being generated from each occlusal portion. Noise phenomenon, the above phenomenon occurs when the motor adopts a double reduction mechanism with output gears, and each large-diameter gear of a pair of counter gears meshes with a pair of worms on the motor shaft with opposite thread directions. even when large load fluctuations are acting on the motor shaft such that the load changes from a load that hinders the rotation of the motor shaft (positive load) to another load that facilitates the rotation of the motor shaft (load load)

Abstract

A motor with a reduction mechanism, the motor comprising a pair of large-diameter gears meshing with a pair of worms located near the motor shaft, the helical directions of the worms being opposite to each other, and a an output gear engaged with small-diameter gears, wherein a spring element is accommodated in a cylindrical groove provided at the rear end of the motor shaft; a sliding element is slidably accommodated in the cylindrical groove; Under the action, the front end of the sliding element is pressed to contact the inner surface of the end of the motor box; and under the elastic force of the spring element, a thrust towards the front end of the motor shaft is always generated in the motor shaft.

Description

technical field [0001] The present invention relates to a motor with a reduction mechanism, suitable for example as a wiper motor or a power window motor and a motor for an electric seat with a reduction mechanism for lifting and lowering a seat. Background technique [0002] As shown in Figures 8 and 9, there is a vehicle seat with a motor of a speed reduction mechanism mentioned above and a motor for an electric seat in the prior art. For example, see also JP-A-2003-56674 (Fig. 1 and Fig. 5 thereof, page 1). [0003] As shown in FIG. 8 , the vehicle seat 1 is installed on the floor F inside the vehicle through the displacement mechanism 2 , and the seat o can move up and down driven by the electric seat motor 3 provided inside the displacement mechanism 2 . [0004] Such as Figure 9 As shown, the electric seat motor 3 has a motor shaft 3b, which protrudes from the motor box 3a and is rotatably supported by a cylindrical part 4a for installing the worm of a gear box 4, an...
