Abstract

The invention relates to the starter technology field, and especially relates to a pre-tightening type starter motor. The pre-tightening type starter motor comprises a stator, a rotor, an end cover and a shell; the stator is placed in the shell, the rotor is placed in the stator, and the end cover is connected on the shell; the stator is equipped with a pin shaft, and the shell is equipped with a shaft hole. The pin shaft and the shaft hole are separately arranged on the stator and shell in a one-to-one corresponding manner, and the stator is connected with the shell by inserting the pin shaft in the shaft hole. A spring sleeves the pin shaft and is clamped between the stator and the shell, the pin shaft is inserted in the shaft hole, and therefore a connecting and fixing function can be fulfilled. The spring enables the stator and the shell to be pre-tightened, so that the stator and the shell can be prevented from mutual loosening, and stability and connection firmness are improved; accordingly, the performance and the work efficiency of a starter are guaranteed, and the service life of the starter is prolonged.

Description

technical field [0001] The invention relates to the technical field of starters, in particular to a pre-tightened starter motor. Background technique [0002] The motor is an important part of the starter. In the prior art, the stator and the housing of the starter motor are mostly connected by screws. The fastness and anti-loosening performance of this connection method are not good. Another kind is to use riveted parts. Connection, but it is easy to fall off, resulting in looseness, which affects the performance and working efficiency of the starter, and also shortens the service life of the starter. Contents of the invention [0003] In order to overcome the disadvantages of poor fastening and easy loosening of the stator of the existing starter motor, which affect the performance and life of the starter, the invention provides a pre-tightened starter motor. [0004] The technical solution adopted by the present invention to solve the technical problem is: a pre-tighte...
