Abstract
The utility model discloses a cylinder roller bearing retainer, including the holder body, the holder body is hollow tubular structure, offers a plurality of pocket holes that are used for installing the roller along the circumference equipartition on the outer periphery of holder body, and the pocket hole be the quad slit structure, is equipped with the notch on the pocket hole on the corresponding side of the axial direction of edge holder body. The utility model discloses a integrative process shaping, for traditional structure, the utility model discloses make manufacturing procedure oversimplify, improved bearing load and life, through at the downthehole notch that sets up of pocket for this holder is when the assembly, and easy plastic deformation produces the pressure point and then pins the cylindrical roller terminal surface, and feasible assembly is easier, and holder and cylindrical roller and bearing inner race or inner circle formation composite entity have improved the bearing quality moreover.
Description
Technical field
This utility model belongs to technical field of bearings, particularly relates to a kind of cylinder roller bearing retainer.
Background technology
It is known that, in field of bearings, the retainer that current cylinder roller bearing is used all is described and claimed in country's rolling bearing standard GB/T-28268, such as second shape retainer, flute profile retainer, M shape retainer, double back-up ring type retainer and entity (copper) retainer etc., these existing retainers, there is structure is complicated, the be equipped with length of cylindrical roller in it, diameter is the least, be difficult to ensure geometry when processing or assemble, easily the shortcoming such as scuffing roller.
Summary of the invention
In order to solve the shortcomings that existing cylinder roller bearing retainer exists, the purpose of this utility model is to provide a kind of cylinder roller bearing retainer.
In order to realize foregoing invention purpose, the technical scheme that this utility model employing is as described below:
A kind of cylinder roller bearing retainer, including retainer body, retainer body is the tubular construction of hollow, the outer circumference surface of retainer body is evenly distributed and offers some pocket holes for installing roller, pocket hole is square opening structure, and pocket hole is provided with notch along the side that the axial direction of retainer body is corresponding.
Further, four angles in pocket hole are arc chord angle.
Further, four angles in described pocket hole are right angle.
Further, the extended distance that two sides the most corresponding on pocket hole are equipped with between inclined-plane, and two inclined-planes becomes larger along the radial direction of retainer body.
Further, the angle α that the extended line on two corresponding on described pocket hole inclined-planes is formed is 0 °～90 °.
Further, the two outermost extended distances in inclined-plane are 3～100mm.
Further, vertical dimension h between outer side edges and the retainer body inner peripheral surface on inclined-plane is 0～6mm.
Further, the extended distance that two sides the most corresponding on pocket hole are equipped with between inclined-plane, and two inclined-planes tapers into along the radial direction of retainer body.
Further, described notch is arc or square.
Further, one of them side of described side offers on notch, or two sides and all offer notch.
Further, pocket hole number is 6～60.
Owing to using technique scheme, this utility model has a following superiority:
This utility model uses and is integrally machined molding, and relative to traditional structure, this utility model makes manufacturing procedure simplify, and improves bearing load and service life；By arranging notch in pocket hole, making this retainer when assembling, easy plastic deformation produces pressure point and then pins cylindrical roller end face so that assembling is more prone to, and retainer and cylindrical roller and bearing outer ring or inner ring form composite entity, improve bearing quality.

Detailed description of the invention
Below in conjunction with the accompanying drawings and the technical solution of the utility model is described in further detail by embodiment.
Embodiment one, such as Fig. 1, shown in 2, a kind of cylinder roller bearing retainer, including retainer body 1, the retainer body 1 tubular construction in hollow, the outer circumference surface of retainer body 1 circumferentially offers some pocket holes 2 for installing roller, pocket hole 2 is square opening structure, and four angles in pocket hole 2 are arc chord angle 4, or it is right angle, it is provided with notch 5 along the side that the axial direction of retainer body is corresponding on pocket hole 2, described notch 5 can only be offered on a side in pocket hole 2, or on two sides in pocket hole, it is equipped with notch 5, described notch 5 is arc or square, preferably, described notch 5 is set to two.
Two sides the most corresponding on described pocket hole 2 are all set to inclined-plane 3, and the extended distance between two inclined-planes 3 becomes larger along the radial direction of retainer body, the angle α that the extended line on two inclined-planes corresponding on described pocket hole 2 is formed is 0 °～90 °；The two outermost extended distances in inclined-plane are 3～100mm；Vertical dimension h between outer side edges and the retainer body inner peripheral surface on inclined-plane is 0～6mm；Pocket hole number is 6～60.
Embodiment two, as it is shown on figure 3, this embodiment is with the difference of embodiment one: the extended distance that two sides the most corresponding on pocket hole 2 are equipped with between inclined-plane, and two inclined-planes tapers into along the radial direction of retainer body.
This utility model passes through ramp structure so that adjusting the radial-play amount of cylindrical roller, and, reduce the CONTACT WITH FRICTION area between pocket hole and cylindrical roller, reduce frictional dissipation, it is possible to increase the whole service life of bearing.
Processing technique of the present utility model is: cylinder processed processing cleaning surface, pocket pore pressure slope rust prevention packaging, for cylinder operation processed, can manufacture after becoming cylinder with steel (copper, aluminum, other alloys etc.) plate drawing, can use steel (copper, aluminum, other alloys etc.) soil weld is cut-out manufacture after cylinder, can form by steel (copper, aluminum, other alloys etc.) pipe car system；For processing pocket hole, pocket hole can use cutting or punch process；Furthermore it is possible to first materials and parts are made after then long cylinder processes pocket hole entirety be again cut to single retainer body, or carry out pockets processing again, subsequently into next procedure after can also first making the retainer body of single finished product cartridge type；Pressure slope operation is that two sides the most corresponding on pocket hole are changed into inclined-plane, its purpose is to so that cylindrical roller easily rotates, additionally, rationally put in place or time bearing requirements is the highest relating to processing, this operation can also be omitted, after retainer body forming requirements is qualified, cleaning surface rust prevention packaging can use requirement to do according to bearing requirements or user.
