Abstract
Disclosed is a straight-line motion ball bearing of a split iron sheet core which is of high temperature resistance and abrasion resistance, of the utility model, composed of four parts including an outer cylinder body, a ball retainer, a steel ball and two lateral plate sealing caps. The ball retainer is assembled by a plurality of iron core plates, and the iron core plate clings to the inner wall of the outer cylinder body, which is assembled into a cylindrical shape pressed and fixed by the lateral plate sealing caps on both ends, the ball retainer being formed. The steel ball is kept among the iron core plates and the outer cylinder body, and the steel ball can move circularly in the circulating motion grooves and operational troughs of the iron core plates. The utility model is of artful design, simple processing and easy installation.
Description
Technical field
The utility model relates to a kind of ball bushing.
Background technique
Linear motion bearing provides to various machinery and is different from the bearing that rotatablely moves, and this class bearing generally adopts steel ball to make rolling element, makes shuttling movement back and forth on some raceways in the cylinder-shaped bearing body of axle.Existing linear bearing manufacturing exists bigger defective, its inner core adopts nylon material to make one substantially, thereby it is wear-resisting inadequately and can only use in the working environment below 80 ℃, as exceeds 95 ℃ of nylon and will be out of shape, and causes the damage that comes off of bearing cisco unity malfunction or steel ball.
Summary of the invention
The purpose of this utility model provides a kind of high temperature resistant, anti abrasive split iron plate core ball bushing.
The utility model has adopted following technological scheme: the utility model is made up of outer cylinder body, ball retainer, steel ball and two side plate capping four major parts, respectively there is a locking groove at the outer cylinder body two ends, ball retainer is to be combined by several pieces same laminations, several pieces laminations are formed columned ball retainer and are fixed in the outer cylinder body by the side plate capping at two ends, and steel ball is made shuttling movement in the steel ball shuttling movement groove of lamination combination ball retainer and work nest; Protrude for arc in the middle of the lamination, the center is a protruding position muscle, the periphery that protrudes is done closing groove and opening work nest of shuttling movement around steel ball, the both sides of groove and work nest are the places, the folded position of lamination combination to same direction bending, two is that the place, position is pressed in the side plate capping, four jiaos of cored respectively combinations of lamination exempt to bump mouth, lamination is combined into can not bumps together when cylindric.
Owing to adopted technique scheme, the utility model to solve to adopt nylon fuse non-refractory, not wear-resisting defective, can exceed three times in nylon fuse working life, the iron plate core can guarantee ball bushing proper functioning under 300 ℃ of high temperature.The utility model design is ingenious, and technology is simple, and is easy to assembly, has broad field of application and popularizing prospect.
Description of drawings
Accompanying drawing 1 is an embodiment's of the utility model a lamination front schematic view.
Accompanying drawing 2 is generalized sections of an embodiment of the utility model.
Accompanying drawing 3 is schematic perspective views of an embodiment of the utility model.
Embodiment
As Fig. 2 and 3, the utility model is by outer cylinder body 1, ball retainer 3, steel ball 2, form with two side plate capping 4 four parts, outer cylinder body 1 is a cylindrical body, cylinder is evenly distributed with four work concave bars, respectively there is a locking groove 5 at two ends, ball retainer 3 is combined into by four laminations 6, four laminations 6 are close to outer cylinder body 1 inwall and are combined into cylindric being pushed down by two end side panels capping 4 and fixedly become ball retainer 3, steel ball 2 is maintained between the inwall of work concave bar of each lamination 6 and outer cylinder body 1, can be in the shuttling movement groove 8 of each lamination 6 and work nest 9 shuttling movement.As Fig. 1, lamination 6 is rectangular watt of shape sheets, the middle protrusion, the center is a protruding position muscle 7, and the periphery of protrusion is done closing groove 8 and opening work nest 9 of shuttling movement around steel ball 2, and the both sides of groove 8 and work nest 9 are to the place, the folded position of lamination 6 combinations 10 of arc-shaped bend in the same way, two is the place, pressure position 11 of side plate capping 4, four jiaos of lamination 6 have combination to exempt to bump mouthfuls 12 respectively, lamination 6 is combined into can not bumps together when cylindric, and its place, folded on one side position also has an assembling to recognize to mouth 13.
Claims (3)
1, a kind of ball bushing, it is made up of outer cylinder body, ball retainer, steel ball and two side plate capping four parts, outer cylinder body is a cylindrical body, cylinder is evenly distributed with the work concave bar, respectively there is a locking groove at two ends, it is characterized in that: ball retainer is to be combined by several pieces same laminations, lamination is close to the outer cylinder body inwall and is combined into cylindric being pushed down by the two end side panels capping and fixedly becomes ball retainer, steel ball is maintained between each lamination and outer cylinder body, can be in the shuttling movement groove of each lamination and work nest shuttling movement.
2, ball bushing as claimed in claim 1, it is characterized in that: protrude for arc in the middle of the lamination, the center is a protruding position muscle, the periphery that protrudes is done closing groove and opening work nest of shuttling movement around steel ball, the both sides of groove and work nest are the places, the folded position of lamination combination to same direction bending, and two is that the place, position is pressed in the side plate capping.
3, linear motion bearing as claimed in claim 1 or 2.It is characterized in that: four jiaos of cored respectively combinations of lamination exempt to bump mouth.
