Abstract
The utility model belongs to the technical field of the micro machine appliance, especially to an iron hoop protective sleeve of a rotating shaft of a micro machine. The iron hoop protective sleeve comprises a circular plate body, and a through hole arranged in the center of the circular plate body. A truncated conical member retracted from top to the bottom is arranged between the circular plate body and the through hole, and the truncated conical member and the circular plate body are in arc transition. The edge side portion of the circular plate body is an annular body perpendicular to the circular plate body, and a plurality of iron pawls bending downwards are uniformly distributed on the annular body. The lower ends of the iron pawls are provided with annular connecting strips, and a gap is arranged between the annular connecting strips and the circular plate body. The iron hoop protective sleeve substantially prolongs the use time of the rotating shaft, thereby prolonging the use time of the micro machine.
Description
Technical field
The utility model belongs to electrical micro-machine apparatus technical field, relates in particular to a kind of iron hoop protective sleeve of electrical micro-machine rotating shaft.
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 purpose of this utility model is to solve above-described technical problem, and a kind of iron hoop protective sleeve of electrical micro-machine rotating shaft is provided, and its technical scheme is as follows:
A kind of iron hoop protective sleeve of electrical micro-machine rotating shaft, it is characterized in that, the iron hoop protective sleeve of described electrical micro-machine rotating shaft comprises circular plate body, described circular plate body middle offers through hole, between circular plate body and through hole, it is the frustum of a cone part shrinking gradually from the bottom to top, arc transition between frustum of a cone part and circular plate body, the edge sidepiece of circular plate body is ring bodies vertical and circular plate body, on described ring bodies, be evenly distributed with some reclinate iron claws, the lower end of described iron claw is grabbed and is provided with annular intercell connector, gapped between annular intercell connector and circular plate body.
When in use, iron hoop protective sleeve is arranged between quiet ball bearing and the inwall of end cap the utility model.Annular intercell connector is to be connected with the inwall of end cap.In through hole, be the axis hole concentric with end cap, for rotating shaft is set.
Iron hoop protective sleeve of the present utility model 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 end cap that whole iron hoop protective sleeve can be stable.
The iron hoop protective sleeve that the utility model provides 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 the inside that is wrapped in of bearing, 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 utility model 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 utility model.
Embodiment
Below in conjunction with Fig. 1, illustrate embodiment:
A kind of iron hoop protective sleeve of electrical micro-machine rotating shaft, it is characterized in that, the iron hoop protective sleeve of described electrical micro-machine rotating shaft comprises circular plate body 1, described circular plate body 1 middle offers through hole 2, between circular plate body 1 and through hole 2, it is the frustum of a cone part 3 shrinking gradually from the bottom to top, arc transition between frustum of a cone part 3 and circular plate body 1, the edge sidepiece of circular plate body 1 is ring bodies 4 vertical and circular plate body 1, on described ring bodies 4, be evenly distributed with some reclinate iron claws 5, the lower end of described iron claw 5 is grabbed and is provided with annular intercell connector 6, gapped between annular intercell connector 6 and circular plate body 1.
When in use, iron hoop protective sleeve is arranged between quiet ball bearing and the inwall of end cap the utility model.Annular intercell connector is to be connected with the inwall of end cap.In through hole, be the axis hole concentric with end cap, for rotating shaft is set.
Iron hoop protective sleeve of the present utility model 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 end cap that whole iron hoop protective sleeve can be stable.
The iron hoop protective sleeve that the utility model provides 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 the inside that is wrapped in of bearing, 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.
