Method for assembling clamp spring and retainer ring of starting motor, special clamp spring awl, clamp spring sleeve and assembly system

Abstract

The invention discloses a high-efficiency reliable-quality method for assembling a clamp spring and a retainer ring of a starting motor, which comprises the following steps of: (1) sleeving the retainer ring on an armature shaft; arranging a clamp spring awl at the end part of the armature shaft, wherein the external surface of the clamp spring awl has a conical surface the diameter of which is gradually increased when the clamp spring awl extents from one end of the armature shaft to the other end of the armature shaft, and the maximum diameter of the conical surface is slighter larger than or equal to the diameter of the armature shaft, and the clamp spring awl after being installed is coaxial with the armature shaft; (2) sleeving the clamp spring on the conical surface of the clamp spring awl, and then sleeving axially in a clamp spring sleeve which is movably matched with the clamp spring awl axially, wherein when moving on the clamp spring awl axially, the clamp spring awl sleeve pushes the clamp spring onto the armature shaft along the conical surface of the clamp spring awl and enables the clamp spring to move axially to a clamp spring groove of the armature shaft and to be blocked in the clamp spring groove; and (3) and pressing the clamp spring in the retainer ring by using the axial relative motion of the retainer ring and the armature shaft. The invention also provides the clamp spring awl, the clamp spring sleeve and an assembly system used in the method.

Description

technical field [0001] The invention relates to the production of a starter motor, in particular to an assembly method of a starter motor retainer ring, a special retainer cone, a retainer taper sleeve and an assembly system. Background technique [0002] Such as Figure 5 As shown, the starter motor rotor assembly is mainly composed of a rotor, a one-way device, a collar, a collar, an armature shaft and other components. There is a circlip groove on the armature shaft near its end, the circlip must be accurately installed and positioned in the circlip groove, and then the circlip is pressed on the circlip so that the circlip is pressed into the clip In the collar groove of the ring, the collar is axially positioned by the circlip. The axial positioning of the circlip and the collar must be accurate. If the error is large, the maximum displacement of the one-way device will be smaller, which will affect the engagement between the one-way device and the flywheel, resulting i...
