Abstract
The utility model relates to technical field of bearings, and definite saying relates to tapered roller bearing, more precisely tapered roller bearing retainer.The technical solution adopted in the utility model is: a kind of novel tapered roller bearing retainer, include conical frame shape main body, conical frame shape main body is along the circumferential direction evenly distributed with multiple tapered fenestras, the small end of described conical frame shape main body is provided with the annular flange of upset to the inside, described annular flange is provided with the pump oilhole distributing along circumferencial direction, and described pump oilhole is the through hole that runs through described annular flange on annular flange thickness direction.Compared with prior art, the pump suction phenomenon while utilizing bearing operation, pumps into more lubricant oil to bearing inside from pump hydraulic fluid port to the utility model, thereby improves the lubricant oil supply of bearing inside, thereby improves bearing internal lubrication performance.
Description
Technical field
The utility model relates to technical field of bearings, and definite saying relates to tapered roller bearing, more precisely tapered roller bearing retainer.
Background technique
Tapered roller bearing belongs to divergence type bearing, and the inside and outside circle of bearing all has tapered raceway; Can bear radial load and axial load.Between the roller large end face of tapered roller bearing and inner ring large-flange, be sliding contact friction, need to lubricate more fully with respect to rolling friction.Tapered roller bearing is in operation process, due to the reason of retainer, its inner lubricant oil easily flows out, thereby cause lubricated insufficient, because can causing roller and large-flange, insufficient lubrication in operation process, produces high temperature, after thermal equilibrium is destroyed, temperature can be more and more higher, finally causes the stuck inefficacy of bearing adhesion.
For solving the problems of the technologies described above, the inventor Wang Bo of our company improves this, and (notice of authorization number is: CN 202326740 U to have declared Chinese patent " tapered roller bearing retainer " in November, 2011, application number is: 201120470321.X), its main structure is: include conical frame shape main body, conical frame shape main body is along the circumferential direction evenly distributed with multiple tapered fenestras, on the large port of conical frame shape main body, be provided with a reducing crimping, on reducing crimping, be along the circumferential direction evenly provided with multiple flutings.Realize and stopped that lubricant oil flows away and stores the dual functions of lubricant oil, thereby ensured the sufficient lubrication at tapered roller bearing roller large end face and tapered roller bearing internal ring large-flange sliding contact position.Although be conducive to stop the loss of lubricant oil, it runs off and still exists, and after certain hour uses, still has lubricated insecure defect.
Summary of the invention
The deficiency existing for prior art, the purpose of this utility model is to provide one can increase lubricant oil supply, can improve the novel tapered roller bearing retainer of bearing internal lubrication.
For achieving the above object, the utility model provides following technological scheme: a kind of novel tapered roller bearing retainer, include conical frame shape main body, conical frame shape main body is along the circumferential direction evenly distributed with multiple tapered fenestras, the small end of described conical frame shape main body is provided with the annular flange of upset to the inside, it is characterized in that: described annular flange is provided with the pump oilhole distributing along circumferencial direction, and described pump oilhole is the through hole that runs through described annular flange on annular flange thickness direction.
By adopting technique scheme, when bearing operation because pump suction phenomenon can pump into more lubricant oil to bearing inside from pump hydraulic fluid port, thereby improve the lubricant oil supply of bearing inside, thereby improve bearing internal lubrication performance.
The utility model is further set to: the radial inner edge wall of described pump oilhole and radially outside wall and described annular flange longitudinal edge wall be arranged in parallel, and each described pump oilhole is distributed on same circular path.
By adopting technique scheme, ensure that the radially interior outer end wall of flange is thick evenly, ensure the intensity of retainer.
The utility model is further set to: on described pump oilhole circumferencial direction, end walls is the circular arc wall towards outer lug, and the radial inner edge wall of described pump oilhole and radially outside wall are connected smoothly through circular arc wall.
By adopting technique scheme, reduce pump oilhole to lubricating oil flow resistance, lubricant oil is entered smooth and easy from pump oilhole, thereby improve greasy property.
The utility model is further set to: described pump oilhole is uniformly-spaced evenly distributed on annular flange.
By adopting technique scheme, not only make pump oil evenly, and make the even intensity of flange.
Below in conjunction with accompanying drawing, the utility model is further described.
Brief description of the drawings
Fig. 1 is the utility model specific embodiment novel tapered roller bearing structural representation;
Fig. 2 is the utility model specific embodiment novel tapered roller bearing retainer axial view;
Fig. 3 is the sectional view dissecing along A-A in Fig. 2.
Embodiment
Referring to accompanying drawing 1 to accompanying drawing 3, the disclosed a kind of novel tapered roller bearing retainer of the utility model, include conical frame shape main body 1, conical frame shape main body 1 is along the circumferential direction evenly distributed with multiple tapered fenestras 2, the small end of described conical frame shape main body 1 is provided with the annular flange 12 of upset to the inside, described annular flange 12 is provided with the pump oilhole 13 distributing along circumferencial direction, and each pump oilhole 13 is equally spaced and is evenly distributed on annular flange 12; Described pump oilhole 13 is for running through the through hole of described annular flange 12 on annular flange 12 thickness directions.
For ensureing the interior outer end even thickness of flange, ensure its even intensity, the radial inner edge wall 131 of described pump oilhole 13 and radially outside wall 132 be arranged in parallel with described annular flange 12 longitudinal edge walls, and each described pump oilhole 13 is distributed on same circular path 3.Certainly oil inlet hole can adopt the hole such as circle, rectangle, but all can not ensure that each pump oilhole equates with annular flange longitudinal edge wall thickness and the interior outer end of the small end of retainer even thickness, even intensity.
For reducing the resistance of oil inlet hole limit portion to lubricating oil flow, on described pump oilhole 13 circumferencial directions, end walls 133 is the circular arc wall towards outer lug, and the radial inner edge wall 131 of described pump oilhole 13 and radially outside wall 132 are connected smoothly through circular arc wall.Under this structural design, reduce pump oilhole to lubricating oil flow resistance, lubricant oil is entered smooth and easy from pump oilhole, thereby improve greasy property.
Novel tapered roller bearing retainer of the present utility model, pump suction phenomenon while utilizing bearing operation, pumps into more lubricant oil to bearing inside from pump hydraulic fluid port, thereby improves the lubricant oil supply of bearing inside, thereby improves bearing internal lubrication performance.
