Abstract
The utility model relates to a novel bidirectional thrust cylindrical roller bearing. The novel bidirectional thrust cylindrical roller bearing comprises a shaft ring, and is characterized in that the shaft ring consists of an upper shaft ring (4) and a lower shaft ring (5), wherein upper row rollers and an upper seat ring (1) are arranged outside the upper shaft ring (4) in sequence; lower row rollers and a lower seat ring (7) are arranged inside the lower shaft ring (5) in sequence; retaining frames are respectively arranged on the upper row rollers and the lower row rollers, wherein an inner partition ring (8) is arranged between the upper seat ring (1) and the lower shaft ring (5) inside the upper row rollers; an outer partition ring (6) is arranged between the lower seat ring (7) and the upper shaft ring (4) outside the lower row rollers. In the bearing disclosed by the utility mode, the conventional one shaft ring is changed into two independent shaft rings, the inner partition ring and the outer partition ring are added, a clearance can be adjusted, and the bearing lock caused by temperature increment is prevented; long rollers and short rollers are adopted, and the difference between the linear speeds in and out of the rollers is reduced, so that the rollers are rotated more flexibly.
Description
Technical field
The utility model relates to a kind of novel bi-directional thrust cylindrical roller bearing.
Background technique
Existing petroleum machinery plunger pump turbine and worm retarder bearing commonly used is the bi-directional thrust cylindrical roller bearing, as shown in Figure 1, by a blowout patche, two seat rings, two retainers and two row rollers form.
Through long-term the use, find, existing plunger pump bi-directional thrust cylindrical roller bearing, its structure has following problem technically: play can't be regulated, and temperature influence is larger; Roller is longer, and the internal and external line speed difference is large, early fatigue easily occurs; Retainer weight is large, affects the revolution flexibility of roller.
The model utility content
The purpose of this utility model is to provide the novel bi-directional thrust cylindrical roller bearing that a kind of reliability is high and the life-span is long.
A kind of novel bi-directional thrust cylindrical roller bearing, comprise blowout patche, its specialization is: described blowout patche is comprised of upper blowout patche and lower blowout patche, the outside of wherein going up blowout patche is provided with row roller and top race successively, and the outside of lower blowout patche is provided with lower row roller and bottom race successively, and on upper row roller and lower row roller, retainer all is installed; Wherein between the top race of upper row roller inboard and lower blowout patche, be provided with cone spacer, and be provided with outer ring spacer between the bottom race in the lower row roller outside and upper blowout patche.
Wherein on upper row roller and lower row roller, the two-piece type retainer all is installed.
Wherein the upper surface inboard of top race is coniform surface for its outside, plane, and the lower surface of the bottom race outside is coniform surface for the inboard, plane.
The lower surface outside of wherein going up blowout patche is coniform surface for its inboard, plane, and the upper surface inboard of lower blowout patche is coniform surface for its outside, plane.
Every group of roller wherein going up in row roller forms by a columned interior roller and a columned outer roller from the inside to the outside, and the cross section of interior roller and outer roller is identical but length interior roller is greater than outer roller.
Wherein descend every group of roller in row roller to form by a columned interior roller and a columned outer roller from the inside to the outside, the cross section of interior roller and outer roller is identical but length interior roller is less than outer roller.
Wherein go up between blowout patche and lower blowout patche and leave gap.
Bearing of the present utility model changes an original blowout patche into two independently blowout patches, increases cone spacer and outer ring spacer, can regulate play, prevents the rising of Yin Wendu and causes the locking of bearing; Adopt long and short roller, reduce roller internal and external line speed difference, make the roller revolution more flexible; The retainer volume reduces, and weight alleviates greatly, is conducive to improve the flexibility of revolution of bearing; Adopt computer optimization to be designed to reinforced structure, make bearing there is higher bearing capacity.Through probationary certificate, in the situation that guarantee to meet rated load, this kind of airframe bearing has certain play, reduce worm screw when axial float and damage that temperature produces while raising, so this airframe bearing can be applied on original petroleum machinery plunger pump turbine and worm retarder, realizes the good results such as high reliability, long lifetime, low cost.
The accompanying drawing explanation
The structural representation that accompanying drawing 1 is the utility model background technique;
Accompanying drawing 2 is structural representation of the present utility model.
Embodiment
As shown in Figure 2, the utility model is a kind of novel bi-directional thrust cylindrical roller bearing, comprises blowout patche, and described blowout patche is formed and left gap between the two by upper blowout patche 4 and lower blowout patche 5, goes up blowout patche 4 and does not contact with lower blowout patche 5.The outside of wherein going up blowout patche 4 is provided with row roller and top race 1 successively, and the outside of lower blowout patche 5 is provided with lower row roller and bottom race 7 successively, and on upper row roller and lower row roller, retainer all is installed.Wherein at the top race 1 of upper row roller inboard and place, lower blowout patche 5(plane) between be provided with cone spacer 8, and on bottom race 7 and the upper blowout patche 4(plane in the lower row roller outside, locate) between be provided with outer ring spacer 6, can control play by cone spacer 8 and outer ring spacer 6.
Wherein on upper row roller and lower row roller, two- piece type retainer 9,10 is installed separately.The upper surface inboard of top race 1 is installed and used requirement for its outside, plane for thereby coniform surface meets, thereby and the lower surface of bottom race 7 outside is installed and used requirement for plane is inboard for coniform surface meets.The lower surface outside of going up in addition blowout patche 4 is coniform surface for its inboard, plane, and the upper surface inboard of lower blowout patche 5 is coniform surface for its outside, plane, has also met and has installed and used requirement.
Every group of roller wherein going up in row roller forms by a columned interior roller 3 and a columned outer roller 2 from the inside to the outside, and the cross section of interior roller 3 and outer roller 2 is identical but length interior roller 3 is greater than outer roller 2.Every group of roller in lower row roller forms by a columned interior roller 3 and a columned outer roller 2 from the inside to the outside, and the cross section of interior roller 3 and outer roller 2 is identical but length interior roller 3 is less than outer roller 2.Adopt the roller that length is different to coordinate, can effectively reduce the impact of internal and external line speed difference on roller and raceway.
