Abstract

A starter armature structure for a vehicle solves the problem of easy deformation without support inside one end of an armature winding of an existing starter armature structure and comprises an armature winding, an armature shaft, a commutator, outer fixing rings and a bearing. The armature winding, the commutator and the bearing are sequentially mounted on the armature shaft, one end of the armature shaft is sleeved on the commutator, and the outer fixings are respectively mounted on the outer sides of two ends of the armature winding. The starter armature structure is characterized in that an inner fixing ring is mounted on the inner side of one end of the armature winding. The starter armature structure ensures no deformation of the inside of the end of the armature winding during assembly by arranging the inner fixing ring at one end of the armature winding without support, avoids contact or interference of the armature winding with the armature shaft or other parts of a starter, precludes the problem of abrasion of the armature winding, simultaneously prevents splashing lubricating oil from a gear and a planetary gear of the armature shaft in meshed rotation from being attached onto the armature winding, and improves running reliability of the starter.

Description

The dynamo-electric pivot structure of vehicle-mounted starting

Technical field

This novel a kind of starter parts, dynamo-electric pivot structure of particularly a kind of vehicle-mounted starting of belonging to of this reality.

Background technology

Armature is the vitals of vehicle-mounted starting machine, and it mainly is made of armature winding, armature shaft, commutator, external fixation ring and bearing etc.Armature winding, commutator and bearing are installed on the armature shaft successively, and an end of armature winding is sleeved on the commutator, and the external fixation ring has two, are installed in the outside at armature winding two ends respectively, and armature winding is played fixation.The subject matter that this starter armature structure exists is, in the parts assembling process of starter armature, armature winding need carry out outside shaping and assembling external fixation ring, because the inside of armature winding one end is not supported, therefore, make the inner generation distortion of this end of armature winding easily, and the end of armature winding is inboard in case bigger distortion occurs, will occur contact or interfering with miscellaneous part, armature winding is worn and torn and damage, defective starter occur.In addition, in the process of starter work, armature shaft gear and planetary gear mesh and high speed rotating, and the lubricating oil that is coated in gear surface will be splashed to along with the rotation of gear on the armature winding, cause armature winding loose contact or short circuit, also can cause defective starter.

Summary of the invention

The technical problems to be solved in the utility model is, overcome the inner problem that does not have support, easy deformation of armature winding one end that existing starter armature structure exists, provide a kind of armature end-connections inboard that support is arranged, the inboard dynamo-electric pivot structure of vehicle-mounted starting of not having distortion.

The utility model comprises armature winding, armature shaft, commutator, external fixation ring and bearing, armature winding, commutator and bearing are installed on the armature shaft successively, one end of armature winding is sleeved on the commutator, the external fixation ring is installed in the outside at armature winding two ends respectively, its special character is, end installed inside at armature winding has the internal fixation ring, guarantees that the inboard, end of armature winding is indeformable.

The utility model is provided with the internal fixation ring at the end that armature winding does not support, the inboard, end of having guaranteed armature winding in assembling process is indeformable, avoided armature winding and armature shaft or starter miscellaneous part to come in contact or interfered, stopped the armature winding wear problems, simultaneously, also avoided the lubricating oil that armature shaft gear and planetary gear engagement rotation is splashed to be attached on the armature winding, inner loose contact of armature or short circuit phenomenon have been avoided, greatly reduce the processing fraction defective of starter armature, improved the starter reliability of operation.
