Abstract
The invention belongs to the technical field of micro-motor equipment, and particularly relates to a micro-motor rotary shaft protection mechanism. The invention discloses a micro-motor rotary shaft protection mechanism which comprises an end cover, wherein the front of the end cover is of a square shape with arc transition at the four corners; four cylindrical through holes are formed at the four corners of the end cover; an iron ring protection sleeve comprises a circular plate body; a through hole is formed at the middle of the circular plate body, and the through hole and the rotary shaft hole are concentric; a cone frustum member gradually contracting from bottom to top is arranged between the circular plate body and the through hole; multiple iron claws bending downward are uniformly distributed at the edge of the circular plate body; the iron claws grab the inner wall of the circular sunken part. By adopting the micro-motor rotary shaft protection mechanism disclosed by the invention, the service time of the rotary shaft is greatly prolonged so that the service time of a micro-motor is greatly prolonged.
Description
Technical field
The invention belongs to electrical micro-machine apparatus technical field, relate in particular to a kind of electrical micro-machine rotating shaft protection mechanism.
Background technology
Electrical micro-machine rotating shaft is the important composition parts of electrical micro-machine, and its Main Function is to play rotary action.Current electrical micro-machine rotating shaft, in the process of installing, often just comes interval or directly contacts with a pad between bearing and the housing of electrical micro-machine.This type of electrical micro-machine rotating shaft protective device, uses after a period of time at electrical micro-machine, and its rotating shaft is subject to the impact of external force to be easy to be worn, thereby causes the fracture of rotating shaft, to such an extent as to shortened the service time of whole electrical micro-machine.
Summary of the invention
The object of the invention is to solve above-described technical problem, a kind of electrical micro-machine rotating shaft protection mechanism is provided, its technical scheme is as follows:
A kind of electrical micro-machine rotating shaft protection mechanism, it is characterized in that, this described electrical micro-machine rotating shaft protection mechanism comprises end cap, and the front of end cap is the square of foursquare arc transition, four jiaos of end cap are provided with four cylindrical holes, each cylindrical hole respectively with the circular arc concentric of end cap corner location; The middle of end cap is provided with circular depression; the middle of circular depression offers shaft hole; the inwall of described shaft hole is provided with quiet ball bearing; between quiet ball bearing and the inwall of circular depression, be provided with iron hoop protective sleeve; iron hoop protective sleeve comprises circular plate body; circular plate body middle offers through hole; through hole and shaft hole concentric; between circular plate body and through hole, it is the frustum of a cone part shrinking gradually from the bottom to top; the edge of circular plate body is evenly distributed with some reclinate iron claws, and iron claw is grabbed on the inwall that is located at circular depression.
Iron hoop protective sleeve of the present invention can well be protected bearing, and frustum of a cone part is that the protection range of rotating shaft is more expanded, and makes rotating shaft more be protected as far as possible.And iron claw is to make on the inwall that is fixed on circular depression that whole iron hoop protective sleeve can be stable.
Electrical micro-machine rotating shaft protection mechanism provided by the invention arranges iron hoop protective sleeve between ball bearing and the inwall of front end housing, can keep like this bearing not affected by external force.Iron hoop protective sleeve, by the whole bearing the inside that is wrapped in, can be avoided bearing to be subject to the impact of external force, and change the effect protection bearing of original just back cushion sheet.
The present invention has extended the service time of rotating shaft greatly, thereby makes to have obtained service time of electrical micro-machine very large growth.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Embodiment
Illustrate embodiment below in conjunction with Fig. 1:
A kind of electrical micro-machine rotating shaft protection mechanism, it is characterized in that, this described electrical micro-machine rotating shaft protection mechanism comprises end cap 1, and the front of end cap 1 is the square of foursquare arc transition, four jiaos of end cap 1 are provided with four cylindrical holes 2, each cylindrical hole 2 respectively with the circular arc concentric of end cap 1 corner location, the middle of end cap 1 is provided with circular depression 3, the middle of circular depression 3 offers shaft hole 4, the inwall of described shaft hole 4 is provided with quiet ball bearing 5, between quiet ball bearing 5 and the inwall of circular depression 3, be provided with iron hoop protective sleeve 6, iron hoop protective sleeve 6 comprises circular plate body 7, circular plate body 7 middles offer through hole 8, through hole 8 and shaft hole 4 concentrics, between circular plate body 7 and through hole 8, it is the frustum of a cone part 9 shrinking gradually from the bottom to top, the edge of circular plate body 7 is evenly distributed with some reclinate iron claws 10, iron claw 10 is grabbed on the inwall that is located at circular depression 3.
Iron hoop protective sleeve of the present invention can well be protected bearing, and frustum of a cone part is that the protection range of rotating shaft is more expanded, and makes rotating shaft more be protected as far as possible.And iron claw is to make on the inwall that is fixed on circular depression that whole iron hoop protective sleeve can be stable.
Electrical micro-machine rotating shaft protection mechanism provided by the invention arranges iron hoop protective sleeve between ball bearing and the inwall of front end housing, can keep like this bearing not affected by external force.Iron hoop protective sleeve, by the whole bearing the inside that is wrapped in, can be avoided bearing to be subject to the impact of external force, and change the effect protection bearing of original just back cushion sheet.
