Abstract

The invention provides a bearing, which comprises an outer ball rail, an inner ball rail and a plurality of ceramic rolling members. The outer ball rail is provided with an annular inner rail plane and corresponds to the outer ball rail, one of the inner ball rail and the outer ball rail is made of ceramic, the other one of the inner ball rail and the outer ball rail is made of a metal material, preferentially, a titanized layer is additionally arranged on the outer surface of the metal material, the inner ball rail is provided with an annular outer rail plane, a ball groove is formed between the inner rail plane and the outer rail plane, and the ceramic rolling members are rotatably arranged in the ball groove. Accordingly, one of the inner ball rail and the outer ball rail, to be the first to bear the stress, can be made of the solid and tough metal material cladded with the titanized layer, the other one of the inner ball rail and the outer ball rail can be made of the same material, namely, the ceramic, as that of the rolling members, and thus, the frictions are reduced, the processing precision is promoted, and the requirements on various characteristics, such as high strength, low friction, low energy consumption and the like, can be met at the same time.

Description

Bearing

Technical field

The invention relates to a kind of bearing.

Background technique

Old-fashioned bearing is to process with steel, but with the bearing that steel are processed the problem of corrosion is arranged easily, and in a single day bearing gets rusty, if do not clean maintenance immediately, and will soon be stuck and can't use.Therefore, old-fashioned bearing is subject to the problems referred to above, is difficult to effective lifting its working life.Wherein, though No. 495590 patents of TaiWan, China disclose aforesaid bearing, change its ball into pottery and process, expectation can reduce friction loss, but still fails effectively to solve the problem that the inside and outside shell of above-mentioned steel gets rusty easily.

In addition, it should be noted that existing bearing gets rusty in order to prevent steel, big city is at the steel surface plated film, and for example No. 495590 patents of TaiWan, China promptly disclose the application of evanohm surface in the inside and outside shell coating of steel.Yet, above-mentioned plated film easily in friction, collision process is impaired, can cause still that steel are exposed to cause lasting oxidation, corrosion.

In order to improve the problems referred to above; The applicant is also proposing like the disclosed bearing structure improvement of TaiWan, China M304599 patent a few days ago; Right the applicant is not as full, and still hope further promotes bearing performance, satisfies the requirement that progresses greatly day by day for performance on the market according to this.

Summary of the invention

Main purpose of the present invention is to provide a kind of bearing that has working strength concurrently and save energy.

For realizing above-mentioned purpose, the present invention adopts following technological scheme:

A kind of bearing comprises:

An outer pearl rail has annular inner orbit face;

An inner integument rail, relative with this outer pearl rail, one of them is pottery for this inside and outside pearl rail, another is the metal material, and this inner integument rail has annular outside track face, encloses ball grooves of structure between the said inside and outside plane of trajectory orbital;

A plurality of ceramic roll pieces are located in this ball grooves rotationally.

Aforesaid bearing, wherein, said metal material outer surface has one deck titanizing layer.

Aforesaid bearing, wherein, this bearing also comprises two ring-type oil sealings, laterally be located between the said inside and outside plane of trajectory orbital, and these two ring-type oil sealings lays respectively at said a plurality of ceramic roll pieces both sides.

Aforesaid bearing wherein, is filled with oiling agent in the said ball grooves

The invention has the beneficial effects as follows:

In the present invention, this inside and outside pearl rail complements each other and makes this bearing integral can reach bearing key performance shock-resistant and the saving energy simultaneously, and can overcome the disappearance that old-fashioned bearing is prone to have the corrosion problem fully, has the effect of remarkable progress really.

Embodiment

Below will the effect that structure characteristic of the present invention and expection thereof are reached be described, but be not category in order to the desire protection of restriction institute of the present invention through preferred embodiment.

Embodiment 1

At first, please be earlier with reference to figure 1 and Fig. 2.In the first embodiment of the present invention, this bearing comprises an outer pearl rail 10, inner integument rail 20, a plurality of ceramic roll piece 30 and two ring-type oil sealings 40.

Should outer pearl rail 10 have an annular inner orbit face 11, this inner integument rail 20 with should be outer pearl rail 10 relative and both are concentric, it be ceramic wherein being somebody's turn to do outer pearl rail 10, inner integument rail 20 then coats a titanizing layer for metal material (for example steel) outer surface.In addition, this inner integument rail 20 has an annular outside track face 21, encloses structure one ball grooves between this inside and outside plane of trajectory orbital.

These a plurality of ceramic roll pieces 30 are located in this ball grooves rotationally; These a plurality of ceramic roll pieces 30 can be ball, roller or other similar aspects; These two ring-type oil sealings 40 then laterally are located between the inside and outside plane of trajectory orbital; And these two ring-type oil sealings 40 lay respectively at this a plurality of ceramic roll pieces 30 both sides, become the sealing shape to make this ball grooves.Preferably, be filled with oiling agent in this ball grooves, to reduce the frictional force that is produced when ceramic roll piece 30 rotates.

In the present embodiment; Because the inner integument rail adopts the outer titanizing layer that coats of firm metal material; Therefore can directly bear bigger stress, for example when this bearing was located between bicycle five-pipe and the crank, this inner integument rail need directly bear the stress of trampling from crank; And speciality such as, toughness firm by itself is suitable for bearing repeated stock and guarantees that bearing keeps stable job state for a long time.And this outer ball is adopted pottery and is processed, and then can effectively promote the frictional force between machining accuracy and minimizing and the ceramic roll piece, and the consumption of saving energy really.

Embodiment 2

Then, please refer to Fig. 3 and Fig. 4.In the second embodiment of the present invention, this bearing also comprises an outer pearl rail 10 ', an inner integument rail 20 ', a plurality of ceramic roll piece 30 and two ring-type oil sealings 40.

Said elements is arranged each other, assembling mode is then identical with first embodiment, both differences be in, in the present embodiment, this outer pearl rail 10 ' is a metal material outsourcing plating titanium layer, this inner integument rail 20 ' then be the pottery.

In like manner, through above-mentioned collocation design, can make the outer pearl rail of present embodiment bearing be suitable for directly meeting with stresses, impact and keep good mechanical strength, and its inner integument rail can guarantee that equally this bearing has the labour-saving advantage.

By on can know that in the present invention, this inside and outside pearl rail complements each other and makes this bearing integral can reach shock-resistant simultaneously and save the bearing key performance of energy, and can overcome the disappearance that old-fashioned bearing is prone to have the corrosion problem fully, has the effect of remarkable progress really.
