In the equipment that some run up, as motor, in use, because motor speed is higher, the lubricating grease added in bearing, under centrifugal action, is easily thrown out of; In addition, be a cylndrical surface because roller bearing structural feature is pocket hole, when bearing working, close, and do not have oil storage space with the complete note of rolling element, and roller and pocket hole area of contact are greatly, fricative heat is large.Thus cause easily occurring noise, easily there is bearing early failue.And for solving the problem, existing to this has been some Curve guide impeller, but it is large to there is difficulty of processing, the defect of using effect difference.
Summary of the invention
For the deficiency that prior art exists, it is good, easy to process that the purpose of this utility model is to provide a kind of greasy property, the cylinder roller bearing retainer of reliable operation and long service life.
For achieving the above object, the utility model provides following technological scheme: a kind of cylinder roller bearing retainer, include retainer body, retainer body is provided with pocket hole, circumference two side, pocket hole is cylndrical surface, it is characterized in that: the circumferential two side in described pocket hole offers oil storage groove, oil storage groove radially extends, described retainer body includes and keeps stand and retainer lid, stand is kept to include end ring and the Kong Liang of global formation, end ring is along the circumferential direction spacedly distributed some Kong Liang, described retainer lid is packed in Kong Liang and is connected on the other end of one end relative to end ring.
By adopting technique scheme, the circumferential two side (i.e. cylndrical surface) in pocket hole offers oil storage groove, being convenient to lubricating grease enters in pocket hole, improve the greasy property in roller and pocket hole, reduce friction, improve working life, due to cylndrical surface and the roller principal contact surfaces in pocket hole, it is offered oil storage groove, oil storage groove easy to process, and effectively reduce the area of contact in roller and pocket hole, reduce friction, roller is rotated more reliable and stable, be more conducive to roller to enter impurity in pocket hole and discharge; Meanwhile, retainer adopts and keeps stand and the assembling of retainer lid to form, and keeps stand and the processing of retainer cover split-type, facilitates the machine shaping of oil storage groove, have advantage easy to process.
The utility model is set to further: described retainer end cap is provided with the riveted joint through hole with hole beam corresponding matching, keeps the hole beam end of stand to be axially extended with riveted joint pin, described Kong Liang rivets pin and be riveted in the riveted joint through hole of retainer end cap.
Under adopting above-mentioned further structural design, the structure of retainer end cap and retainer pedestal is simple, reliably easy to assembly.
The utility model is set to further again: described retainer end-cover axle offers inner circular groove on an end face in corresponding pocket hole, inner side port on described riveted holes is positioned at inner circular groove, described retainer end-cover axle is provided with outer end annular groove to away from one end, pocket hole end face, outer end annular groove is relative with inner ring groove position, outer end annular groove axial cross section shape is the taper that bottom is little, oral area is large, the outside port of described riveted holes is positioned at outer end annular groove, and the riveted joint termination of riveted joint pin is positioned at outer end annular groove.
Under adopting above-mentioned further structural design again, the design of inner circular groove makes the corresponding face area on retainer end cap in pocket hole reduce, and reduces the frictional force of roller rolls, makes work more reliable, also can store lubricating grease, improve greasy property; And, make retainer end cap and hole beam support reliably, assemble solid and reliable, ensure the reliability of retainer and improve working life; The design of outer end annular groove, facilitates riveting, and makes to rivet rear compact structure.
The utility model is set to further: the circumferential two side in described pocket hole all offers two oil storage grooves, and two oil storage grooves are arranged vertically.
Under adopting above-mentioned further structural design, lubrication effect is better, operates more stable, and processing also facilitates.
Below in conjunction with accompanying drawing, the utility model is further described.
