Description
Technical field
The utility model is related to technical field of bearings, is specifically linear ball bearing, more precisely be straight-line ball
The outer ring assembl of bearing.
Background technology
Linear bearing is a kind of linear motion system, is used cooperatively for rectilinear path with cylinder axis.Existing ordinary straight
Steel ball directly contacts cylindrical shaft and cylindrical outer ring to line motion bearings when in use, and steel ball and axle and cylindrical outer ring are all a little
Contact, this design feature determines that bearing can not aligning.
The content of the invention
In view of the deficienciess of the prior art, the purpose of this utility model is that providing one kind realizes that bearing possesses aligning work(
The linear ball bearing outer ring assembl of energy.
To achieve the above object, the utility model provides following technical scheme：A kind of linear ball bearing outer ring assembl,
Outer ring body including tubular, it is characterised in that：Circumferentially being spacedly distributed on described outer ring body has some axially extending
Bar pad board slot, positioning is provided with steel ball backing plate, the madial wall of the steel ball backing plate in bar pad board slot is provided with vertically
In the circular arc being adapted to outer ring body in bal guide, the lateral wall circumference of steel ball backing plate, the lateral wall axial direction of steel ball backing plate
The upper circular arc low in middle high, two ends.
By using above-mentioned technical proposal, designed using steel ball backing plate, be the arc of protrusion in the middle of steel ball backing plate, both sides compared with
It is thin, thus a pivot point is formed, the effect of this central point is, when the center line of axle and bearing deviates, can be to it
Compensate, that is, realize zero offset capability.
It is preferred that, the outer ring body correspondence is provided with interior stage portion, the steel in the axial end positions of bar pad board slot
The axial two ends of ball pad plate are provided with outer step portion, and the outer step portion of the steel ball backing plate is corresponding with outer ring body upper inner platform rank portion to match somebody with somebody
Close.Under the structure design, bar pad board slot and steel ball backing plate use and set inside and outside stage portion to be coordinated in axial end positions,
Its is simple in construction, it is easy to process and be easy to assembling.
It is preferred that, the aperture surface of the steel ball backing plate protrudes the inner peripheral surface of outer ring body, bal guide radial section shape
Shape is the arcs of recesses being adapted to ball.Under the structure design, the aperture surface protrusion design of steel ball backing plate is easy to process thereon
Bal guide be adapted to ball, the tubular outer ring of more traditional global shape is compared, the increase of the contact area of ball,
So as to improve bearing capacity.
It is preferred that, the outer ring body is the working of plastics that plastics are made, and the steel ball backing plate is steel plate.The structure design
Under, working of plastics is used as the outer ring body of whole supporting frame, steel ball backing plate uses steel plate design, it is ensured that same using reliability
When reduce cost.
The utility model is further described below in conjunction with the accompanying drawings.
Brief description of the drawings
Fig. 1 is that the linear ball bearing structure that the utility model specific embodiment has linear ball bearing outer ring assembl is shown
It is intended to；
Fig. 2 is part A partial enlarged view in Fig. 1；
Fig. 3 is the axial schematic diagram of steel ball backing plate of the utility model specific embodiment；
Fig. 4 is the lateral view of steel ball backing plate of the utility model specific embodiment.
Embodiment
Referring to accompanying drawing 1 to accompanying drawing 4, a kind of linear ball bearing outer ring assembl disclosed in the utility model, including tubular
Circumferentially being spacedly distributed on outer ring body 1, described outer ring body 1 has some axially extending bar pad board slots 10, bar shaped
Positioning is provided with steel ball backing plate 2, the madial wall of the steel ball backing plate 2 in backing plate groove 10 is provided with bal guide 21, steel vertically
In the circular arc R1 being adapted to outer ring body 1 in the lateral wall circumference of ball pad plate 2, in being on the lateral wall axial direction of steel ball backing plate 2
Between the low circular arc R2 in high, two ends.Wherein, the outer ring body is the working of plastics that plastics are made, such as formaldehyde resin, the steel ball
Backing plate is steel plate, such as bearing steel.Working of plastics is used as the outer ring body of whole supporting frame, steel ball backing plate is set using steel plate
Meter, it is ensured that reduce cost simultaneously using reliability.
In this specific embodiment, the correspondence of outer ring body 1 is provided with interior step in the axial end positions of bar pad board slot
Portion 11, i.e., set corresponding with bar pad board slot axial end position on the inner peripheral surface of outer ring body 1 and connect interior step groove,
The axial two ends of the steel ball backing plate 2 are provided with outer step portion 22, i.e., on the outer radial side wall of the axial end position of steel ball backing plate
Provided with outer step groove, outer step portion 22 and the corresponding matching of 1 upper inner platform rank portion of outer ring body 11 of the steel ball backing plate 2, so that will
Steel ball backing plate 2 is limited in the bar pad board slot of outer ring body 1.Bar pad board slot and steel ball backing plate are used in axial end positions
Inside and outside stage portion is set to be coordinated, its is simple in construction, it is easy to process and be easy to assemble.Certainly it is feasible as the utility model
Scheme, also corresponding groove can be set in the both lateral sides of steel ball backing plate（Groove can be step-like or concave shape groove）, accordingly exist
Fit structure is set in the axial side wall of bar pad board slot；But under the structure, due to outer body and the thinner thickness of steel ball backing plate,
It is processed vertically, there is processing inconvenience or the poor defect of reliability.
In addition, the aperture surface 23 of the steel ball backing plate 2 protrudes the inner peripheral surface of outer ring body 1, bal guide 21 is radially cut
Face is shaped as the arcs of recesses being adapted to ball.The aperture surface protrusion design of steel ball backing plate, is easy to the ball processed thereon to lead
Groove is adapted to ball, and the tubular outer ring of more traditional global shape is compared, the contact area increase of ball, so as to improve
Bearing capacity.
Outer ring is designed using component on the utility model linear bearing, is the arc of protrusion in the middle of steel ball backing plate, both sides compared with
It is thin, thus a pivot point is formed, the effect of this central point is, when the center line of axle and bearing deviates, can be to it
Compensate, that is, realize zero offset capability.
