Abstract
The utility model discloses a kind of copper cage, its drip irrigation device comprises retainer body, described retainer body is ring, described retainer body is provided with pocket hole, described pocket hole is formed with the opening put into for ball at the side place of retainer body, the bottom in pocket hole to lower recess and and form space between ball, the both sides bottom described pocket hole and ball abut against, and reach the effect that the sphere-contact area of surface bottom pocket hole and ball is less.
Description
Technical field
The utility model relates to a kind of bearing, and more particularly, it relates to a kind of copper cage.
Background technique
Retainer is one of major part of bearing, and retainer has four basic roles in rolling bearing: one, be separated rolling element; Two, rolling element itself is maintained or is made itself and a lasso keep together; Three, rolling element is guided to roll on the right track; Four, minimizing frictional force directed to rolling element.The retainer of conventional ball bearings is that ball is encased a circle, and ball rotates in the pocket hole on retainer, and bearing mostly is metallic material and makes, and adopt the bearing that metallic material is made, high temperature resistant, wear resistance is all better.
The retainer that bearing uses is also varied, and have S shape retainer, crown cage etc., material is also varied, and the entity crown cage made with brass material is the one in the retainer structure that uses of current deep groove ball bearing.Crown cage comprises the retainer body of ring-type, retainer body is provided with multiple pocket hole, and the part in pocket hole forms the opening put into for ball in the side of the retainer body of ring-type, concrete structure can application reference number be 200720092884.3 patent.The bottom in existing crown cage pocket hole is all inconsistent settings with ball outside surface, but the surface bottom pocket hole and the sphere of ball fit, there is no space, the area of contact of the surface bottom the pocket hole made and the sphere of ball is larger, the area of friction is comparatively large, and friction is comparatively violent, and ball easily weares and teares, easy generation stuck phenomenon, affects the using effect of bearing.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is the copper cage providing the sphere-contact area of the surface bottom a kind of pocket hole and ball less.
For achieving the above object, the utility model provides following technological scheme: a kind of crown cage, comprise retainer body, described retainer body is ring, described retainer body is provided with pocket hole, described pocket hole is formed with the opening put into for ball at the side place of retainer body, the bottom in pocket hole to lower recess and and form space between ball, the both sides bottom described pocket hole and ball abut against.
Preferably, the lower surface in pocket hole is circular arc.
Preferably, be formed with separation beam between adjacent pocket hole, described separation beam opening side raises up and forms lock ball block.
Preferably, the arranged outside of lock ball block has plane of inclination.
Preferably, retainer body is outward-dipping and form an acute angle with vertical plane.
Preferably, acute angle is between 1 ° to 5 °.
Preferably, the outwardly formation arc surface in the outside of retainer body.
Preferably, lubricating grease is provided with in space.
By adopting technique scheme, the bottom in pocket hole to lower recess and and form space between ball, the both sides bottom pocket hole and ball abut against, when ball loads behind pocket hole, ball abuts with the both sides bottom pocket hole, can be stable locate ball, and in the middle part of pocket hole and between ball, have certain distance, can not touch with ball, thus when ball rolls, less with the friction area of ball bottom pocket hole, ball is not easy wearing and tearing, is also less likely to occur the phenomenon blocked.

Embodiment
With reference to accompanying drawing, the utility model copper cage embodiment is described further.
A kind of copper cage, comprise retainer body 1, retainer body 1 is in ring, retainer body 1 is provided with pocket hole 2, pocket hole 2 is formed with the opening put into for ball 6 at the side place of retainer body 1, the bottom in pocket hole 2 to lower recess and and form space 7 between ball 6, can in space 7 storing lubricating grease or lubricant oil easily, the lubrication of ball 6 can be ensured, be not easy to block during ball 6 Free-rolling, both sides bottom pocket hole 2 and ball 6 abut against, after ball 6 loads pocket hole 2, ball 6 abuts with the both sides bottom pocket hole 2, can be stable locate ball 6, and in the middle part of pocket hole 2 and between ball 6, have certain distance, can not touch with ball 6, thus when ball 6 rolls, less with the friction area of ball 6 bottom pocket hole 2, ball 6 is not easy wearing and tearing, also the phenomenon blocked is less likely to occur.Meanwhile, retainer can be made of copper, and such arranges retainer body 1 more corrosion-resistant and high-temperature resistant, and rust-proof effect is also better, certainly, can arrange multiple pocket hole, can place more ball, strengthens the bearing capacity of bearing.
Bottom pocket hole 2 to lower recess be circular arc, when ball 6 rolls, active force can be produced to the bottom in pocket hole 2, and power can be disperseed when being subject to active force by the bottom of circular arc comparatively uniformly, stress is made to be difficult to concentrate, ensure that pocket hole 2 is less likely to occur distortion or damages time stressed, simultaneously circular arc surface can more conveniently with the plane tangent of ball 6, the area of contact reducing bottom and ball 6 to a greater extent, thus make ball 6 be not easy wearing and tearing, be also less likely to occur the phenomenon blocked.
In order to more stable locates ball 6, separation beam raises up in opening side and forms lock ball block 3, adjacent lock ball block 3 can clamp ball 6, simultaneously, the bearing surface clamping ball 6 also can be the plane tangent with ball 6, while can ensureing that ball 6 can stablize rolling in pocket hole 2 like this, ensure that the amount of friction of ball 6 is less.
As preferably, retainer body 1 tilts laterally, and form an acute angle a with vertical plane, such setting when ball 6 be subject to active force conduct to retainer body 1 time, retainer body 1 can provide axially certain and radial component, better support ball 6, ensure the rolling that ball 6 can be stable.Meanwhile, acute angle a can be arranged between 1 ° to 5 °, can be preferably 3 °, if the component of the too little radial direction of angle is also relatively little, can not play good effect, if angle is too large, retainer can be inconvenient to load among bearing, is easily stuck during rotation.Certainly, the outside of lock ball block 3 can arrange a plane of inclination 4, the area encasing ball 6 can be reduced on the one hand, can make ball 6 Free-rolling more easily, the phenomenon blocked is less likely to occur, another is convenient, when retainer body 1 will load in bearing, certain guiding function can be played in plane of inclination 4, makes retainer body 1 conveniently to load in bearing, the phenomenon blocked is less likely to occur.
In addition, the outwardly formation arc surface 5 in outside of retainer body 1, projection plays certain reinforing function, and arc surface 5 can play better peptizaiton by counter stress simultaneously, ensure the stability of retainer body 1 structure, ensure that retainer body 1 distortion is less likely to occur or damages.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
