Description
Technical field
The utility model relates to thrust ball bearing, is specifically a kind of angular contact thrust ball bearing, the more precisely retainer of thrust angular contact thrust ball bearing.
Background technique
Angular contact thrust ball bearing is a kind of bearing mainly bearing axial load forces; It is well utilized in automobile absorber.Automobile absorber Main Function is concussion when rebounding after suppressing spring shock-absorbing and the impact from road surface, accelerates the decay of vehicle frame and body vibrations thus improves the driving comfort of automobile.Angular contact thrust ball bearing is positioned at the upper end of absorber spring, plays a supportive role.
The retainer of thrust angular contact device ball bearing inside is used for being separated by steel ball and guiding steel ball along certain orbiting motion, and it is various informative, comprises different materials and different structure.The pocket hole of major part retainer is spherical, steel ball press-loading needs certain power, secondly due to the finite gap between steel ball and pocket hole, the lubricating grease amount existed between steel ball and pocket hole is also limited, in addition the bearing rotating speed on vibration damper very low (being swing substantially), for forming better lubricant film, needs lubricating grease more more than other bearings, therefore existing angular contact thrust ball bearing can not meet usage requirement, affects bearing working life; In addition due to limited space between bearing inner race road, retainer structure imperfection may cause retainer to contact with raceway groove and cause raceway groove to scratch, increase the surface friction drag of bearing.
Summary of the invention
For the deficiency that prior art exists, it is easy to assembly that the purpose of this utility model is to provide a kind of steel ball, time saving and energy saving, and lubricating grease packing space between steel ball and retainer pocket hole is large, can store the angular contact thrust ball bearing retainer of more lubricating grease during use.
For achieving the above object, the utility model provides following technological scheme: a kind of angular contact thrust ball bearing retainer, include taper support body in the form of a ring, taper support body is provided with the pocket hole of a circle for steel ball assembling, and the Kong Liang between adjacent pocket hole, it is characterized in that: described pocket hole is made up of sphere hole and cylinder face, sphere hole and cylinder face tangent, the hole wall of sphere hole and the hole wall of cylinder face are connected smoothly, described sphere hole is positioned at taper support body small end one end, cylinder face is positioned at the large end one end of taper support body, and the described sphere hole port be positioned at inside taper support body is greater than the port that sphere hole is positioned at the external side of conical mount, form described pocket hole large towards one end port inside taper support body, one end port towards the external side of conical mount is little, the large port in pocket hole is steel ball loading port, the portlet in pocket hole is that steel-ball limiting keeps mouth, the gyration center line in described pocket hole and the axis parallel of taper support body.。
By adopting technique scheme, during steel ball assembling, the port that can be positioned at inside taper support body from pocket hole taper support body is directly put into, and the port that pocket hole is positioned at the external side of conical mount keeps steel-ball limiting, prevents steel ball from dropping out, pressure assembling force is not needed during assembling steel ball, easy to assembly, improve efficiency of assembling, and cylinder face effectively increases the gap between steel ball, improve the loading of lubricating grease, improve lubrication effect.
The utility model is set to further: described taper support body is evenly equipped with some supporting convex, and supporting convex is positioned at Kong Liang towards on side, conical mount external side one.Under this vibrational power flow, supporting convex realizes retainer to be bearing on race ring, and be dot point, produce between the raceway groove avoiding retainer and race ring and interfere and the raceway groove that causes scratches and surface friction drag increases, thus thus improve bearing usability and life-span significantly.
The utility model is set to further: the supporting bottom surface of described supporting convex is sphere.Under this structural design, retainer and race ring frictional force little, thus thus improve bearing usability and life-span significantly.
Below in conjunction with accompanying drawing, the utility model is further described.

Embodiment
See accompanying drawing 1-5, a kind of angular contact thrust ball bearing retainer disclosed in the utility model, includes taper support body 1 in the form of a ring, and taper support body 1 is provided with the pocket hole 2 of a circle for steel ball assembling, and the hole beam 3 between adjacent pocket hole 2, described pocket hole 2 is made up of sphere hole 21 and cylinder face 22, sphere hole 21 is tangent with cylinder face 22, the hole wall of sphere hole 21 and the hole wall of cylinder face 22 are connected smoothly, described sphere hole 21 is positioned at taper support body 1 small end one end, cylinder face 22 is positioned at taper support body 1 and holds one end greatly, and described sphere hole 21 port be positioned at inside taper support body 1 is greater than sphere hole 21 is positioned at port outside taper support body 1, form described pocket hole 2 large towards one end port inside taper support body 1, little towards one end port outside taper support body 1, the large port in pocket hole 2 is steel ball loading port 23, the portlet in pocket hole 2 is that steel-ball limiting keeps mouth 24, the gyration center line 23 in described pocket hole 2 and the axis parallel of taper support body 1, under this design, ensure steel ball stability of rotation in pocket hole.As shown in Figure 4, steel ball 3 forms comparatively wide arc gap, improves the loading of lubricating grease after loading between cylinder face 22 and steel ball 3, improve lubrication effect, during steel ball assembling, can directly put into by the port (steel ball loading port 23) be positioned at from pocket hole 2 taper support body 1 inside taper support body 1, the port (steel-ball limiting keeps mouth 24) that pocket hole 2 is positioned at outside taper support body 1 keeps steel-ball limiting, prevent steel ball from dropping out, pressure assembling force is not needed during assembling steel ball, easy to assembly, improve efficiency of assembling.
For ensureing that taper support body loads after in race ring, being formed and effectively supporting, described taper support body 1 is evenly equipped with some supporting convex 4, supporting convex 4 is positioned at hole beam 3 towards on a side outside taper support body 1; In this specific embodiment, supporting convex 4 has 3.Under this vibrational power flow, supporting convex realizes retainer to be bearing on race ring, and be dot point, produce between the raceway groove avoiding retainer and race ring and interfere and the raceway groove that causes scratches and surface friction drag increases, thus thus improve bearing usability and life-span significantly.
Further, the supporting bottom surface of described supporting convex 4 is sphere 41.Under spherical design, retainer and race ring frictional force little, thus thus improve bearing usability and life-span significantly.
