Embodiment Construction

[0027] see figure 1 and figure 2 , the automobile motor assembly with a double rolling bearing mechanism shown in the figure includes: a motor 100, the motor 100 includes a motor output shaft 110 and an electric drive part 120, and the electric drive part 120 drives the output shaft to rotate. One end of the motor output shaft 110 is supported on the motor housing (not shown in the figure) through the oil bearing 130 .

[0028] The automobile motor assembly with a double rolling bearing mechanism also includes a worm 210 , a worm wheel 310 and a reduction body (not shown) for assembling the worm 210 and the worm wheel 310 .

[0029] The worm 210 is installed on the worm end 220 of the output shaft 110 of the motor, and the worm end 220 of the output shaft 110 of the motor is supported in the reduction body through rolling bearings 230 , 240 . On the worm end 220 of the output shaft 110 of the motor, there are also worm elastic positioning taper sleeves 250 , 260 , and each ...

Abstract

The invention discloses an automobile motor assembly with a double rolling bearing structure. The automobile motor assembly comprises a motor, a worm, a worm gear, and a reducing box for assembling the worm and the worm gear, wherein the motor comprises a motor output shaft and an electric drive component; the electric drive component drives the motor output shaft to rotate; the worm is arranged at a worm end of the motor output shaft; the worm gear and the worm are in drive connection; and the worm end of the motor output shaft is supported in the reducing body through two rolling bearings. The two rolling bearings are adopted and the radial clearance is very small, so that the worm and the worm end of the motor output shaft do not bend when the worm gear bears very high radial force, and the worm and the worm gear are always meshed on a node, thereby ensuring the transmission efficiency and improving the strength of the worm gear and the worm.

Description

technical field [0001] The invention relates to the technical field of automobile motors, in particular to an automobile motor assembly with a double rolling bearing mechanism. Background technique [0002] At present, most of the automotive motor components with worm gears and worms use one rolling bearing and one or two sliding bearings as the transmission support. The gap fit, so that when the motor is subjected to a large force, one end of the worm is unsupported and the worm shaft is bent. This bending will cause the meshing between the worm and the worm wheel to be different from the node, resulting in reduced transmission efficiency and increased heat generation, etc. In severe cases, it will also cause damage to the tooth surface of the worm. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an automobile motor assembly with a double rolling bearing mechanism in view of the above-mentioned technical proble...
