An assembly method of a starter motor with a built-in electromagnetic switch

Abstract

The invention discloses an assembling method for a starting motor with a built-in electromagnetic switch. The starting motor comprises a starting motor shell with a motor installing hole, an inner gear shaft hole, an isolator installing portion and an electromagnetic switch installing portion. The assembling method comprises the steps that 1, all parts of an electromagnetic switch assembly and the starting motor shell are directly connected into a whole; 2, an inner gear assembly is installed in the inner gear shaft hole; 3, an isolator assembly is pressed into the isolator installing portion of the starting motor shell, and a starting motor front cover is arranged in a covering manner and fixed; and 4, an obtained assembly is placed reversely, and after a motor assembly is installed in the motor installing hole, a starting motor back cover is arranged in a covering manner and fixed. According to the assembling method, through the means that all the parts of the electromagnetic switch assembly and the starting motor shell are integrally connected in a creative and direct manner, the problem that in the prior art, a coil assembly is damaged or the connecting reliability is poor is solved, and the technical problems of overall assembling of the starting motor with the built-in electromagnetic switch are solved.

Description

technical field [0001] The invention relates to an assembly method of a starter motor, in particular to an assembly method of a starter motor with a built-in electromagnetic switch. Background technique [0002] The starter motor is an important part of the car, its function is to start the car engine. The starter motor is powered by the battery, and is controlled by an electromagnetic switch to convert electrical energy into mechanical energy to output power. The one-way clutch makes the engine run from a standstill until the engine is ignited and runs normally. In the prior art, the electromagnetic switch of the starter motor is an independent integral part, which is installed on the front cover or the middle cover of the starter motor with screws, and the fork is pulled by the hook on the moving core machine assembly in the electromagnetic switch to make it The starter motor freewheel assembly moves. For example, the Chinese invention patent application with the publica...

Problems solved by technology

This assembly method creatively changes the existing method of assembling the electromagnetic switch assembly into an independent whole through various connection means and then connects it with the starter motor housing, and directly connects the components of the electromagnetic switch assembly with the starter motor. The integral connection of the shell solves the problem in the prior art that the welding process is easy to cause damage to the coil assembly during independent installation or the riveting has poor connection reliability due to the limitation of material strength; and through reasonable setting of the assembly process and tooling, it is solved. Solved the technical problems of the overall assembly of the electromagnetic switch built-in starter motor
