Bearing internal pressure cover attaching structure on motor
Technical field
The present invention relates to motor fields, and in particular to the bearing internal pressure cover attaching structure on a kind of motor.
Background technique
As people are highly integrated for chip, the demand of miniaturization, the bearing internal pressure cover attaching structure of the side of motor
Connection with itself is important a part of its work, when its structural instability, will affect entire motor workability
Energy.
Summary of the invention
The purpose of the present invention is overcoming the above problem, the bearing internal pressure cover attaching structure on motor, including axis are developed
It holds, fixed installing connection structure on bearing, which is characterized in that the connection structure includes that the recessed of the left and right sides connects one He of platform
It is recessed to connect platform two, and the two middle position at be equipped with it is convex connect platform, the convex outside for connecing platform is equipped with several circular
Connected unit connects platform one and recessed to connect the face that platform two contacts be arc-shaped setting with recessed.
Preferably, it is described it is recessed connect platform one and it is recessed connect be equipped on platform two several recess arc-shaped shape contact platform.
Preferably, the convex front and rear sides for connecing platform be respectively equipped with it is arc-shaped it is convex connect block, and make described convex to connect block point
Not with it is recessed connect platform one, it is recessed connect on platform two arc-shaped shape contact platform mutually coincide.
Preferably, the recessed platform one and the recessed platform two that connects of connecing is T-shaped setting, and it connects platform one with convex
It is moulded into.
Bearing internal pressure cover attaching structure on motor of the present invention, the beneficial effect is that, pass through described one group
The recessed setting for connecing platform, more stable when shaft-cup is connect with holding, device connected with outer casing is not easy to shake, and stability is good, more
With practicability.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention;
Fig. 2 is the enlarged drawing of A;
Wherein, 1- connection structure, 2- is recessed to connect platform one, and 3- is recessed to connect platform two, and 4- is convex to connect platform, 41- connected unit.
Specific embodiment
In order to enable those skilled in the art to better understand the solution of the present invention, below in conjunction in the embodiment of the present invention
Attached drawing, technical scheme in the embodiment of the invention is clearly and completely described.Obviously, described embodiment is only
A part of the embodiment of the present invention gives presently preferred embodiments of the present invention instead of all the embodiments in attached drawing.The present invention can
To realize in many different forms, however it is not limited to embodiment described herein, on the contrary, provide the mesh of these embodiments
Be to make the disclosure of the present invention more thorough and comprehensive.Based on the embodiments of the present invention, the common skill in this field
Art personnel every other embodiment obtained without creative efforts belongs to the model that the present invention protects
It encloses.
Embodiment, in conjunction with attached drawing 1-2, bearing internal pressure cover attaching structure on motor, including bearing is fixed on bearing
Install connection structure 1, the connection structure 1 include the left and right sides it is recessed connect platform 1 and it is recessed connect platform 23, and in the two
Meta position is set to be equipped with convex and connects platform 4, and the convex outside for connecing platform 4 is equipped with several circular connected units 41, with it is recessed connect it is flat
Platform 1 and the recessed face for connecing the contact of platform 23 are arc-shaped setting.
It is described it is recessed connect platform 1 and it is recessed connect be equipped on platform 23 several recess arc-shaped shape contact platform.It is described convex to connect
The front and rear sides of platform 4 be respectively equipped with it is arc-shaped it is convex connect block, and make it is described it is convex connect block respectively with it is recessed connect platform 1, it is recessed connect it is flat
Arc-shaped shape contact platform on platform 24 mutually coincide.The recessed platform 1 and the recessed platform 23 that connects of connecing is T-shaped setting, and
And it is integrally moulded into the convex platform 4 that connects.
The above are presently preferred embodiments of the present invention, are not intended to limit the scope of the patents of the invention, although referring to aforementioned implementation
Invention is explained in detail for example, still can be to aforementioned each specific for coming for those skilled in the art
Technical solution documented by embodiment is modified, or carries out equivalence replacement to part of technical characteristic.All utilizations
The equivalent structure that description of the invention and accompanying drawing content are done directly or indirectly is used in other related technical areas, together
Reason is within the invention patent protection scope.
