Description
Technical field
The utility model is related to a kind of bearings, and in particular to a kind of plane axis applied on motorcycle or bicycle
It holds.
Background technology
For bearing as a kind of important spare part in mechanical equipment, function is the mechanical rotary body of support, reduces it and is moved through
Friction coefficient in journey, while ensureing rotating accuracy.There are many kinds of bearings, and which includes deep groove ball bearing, aligning roller axis
It holds, taper roll bearing, needle bearing, cylinder roller bearing etc., distinct device and different operating modes select different types of axis
It holds.This application involves be a kind of plane bearing, plane bearing is generally by Upper gasket, lower gasket, retainer and several steel
Pearl is constituted, and steel ball is mounted in retainer, and retainer is clipped between Upper gasket and lower gasket, and steel ball realizes point with Upper gasket and lower gasket
Contact；The aperture of Upper gasket is less than the aperture of lower gasket, and shaft is mounted in the hole of Upper gasket；When work, Upper gasket is with shaft
It rotates together.Retainer has copper alloy cutting retainer, steel plate punched retainer, pin type retainer, forming synthetic resin to keep
Frame selects the retainer of unlike material according to distinct device from different operating modes.Regular Bicycle, motorcycle, electric vehicle etc. at present
The smaller small mechanical equipment of load is because in view of cost and actual needs, being generally used the plane that retainer is synthetic resin
Bearing.However due to being limited by structure, current this plane bearing is easy to be influenced and occur by various operating mode factors
Design requirement is not achieved in damage, bearing actual life.
Invention content
In view of the shortcomings of the prior art, the utility model innovation provides a kind of durable type vehicle that the service life is longer
Use plane bearing.The automobile-used plane bearing of the durable type includes Upper gasket, lower gasket, retainer and several steel balls, described
Several steel ball slots are along the circumferential direction offered on retainer, the steel ball matching is arranged in the steel ball slot of retainer,
It is characterized in that：The retainer is in bowl face shape, and the steel ball slot of the retainer is evenly distributed on the inclined-plane of retainer.
The Upper gasket has a upper pad portion, and the periphery in the upper pad portion is and the matched upper cambered surface raceway of steel ball.
There is the Upper gasket middle part, the diameter of the middle part to be more than the diameter in upper pad portion.
The Upper gasket middle part is line contact surface close to the bottom surface of outer circle.
The raised underlay portion of lower gasket, the periphery in the underlay portion are to be rolled with the matched lower camber side of steel ball
Road.
The lower gasket is line contact surface close to the top surface of inner circle.
Reinforcing rib is equipped on the retainer between two neighboring ball slot.
According to a kind of automobile-used plane bearing of durable type provided by the utility model, have the following technical effect that：1, due to inciting somebody to action
Retainer is fabricated to bowl face shape, and the steel ball that retainer can carry is more, correspondingly, the power that each steel ball is born when in use is more
Small, bearing pitting corrosion resistant performance is stronger；2, radial load and bi-directional axial load can be born, particularly radial load-bearing capacity is big, fits
For bearing heavy load and impact load；3, since Upper gasket and lower gasket use novel structure design, this plane bearing
It is wear-resistant, anti-fatigue ability is stronger.
Description of the drawings
Fig. 1 is the explosive view of the utility model（Lower gasket is sectional view）；
Fig. 2 is the structural schematic diagram of retainer.
Specific implementation mode
As shown in Figure 1, this automobile-used plane bearing of durable type includes Upper gasket 1, lower gasket 3, retainer 2 and several
A steel ball（Steel ball is not drawn into）, several steel ball slots 21 are along the circumferential direction offered on retainer 2, steel ball matching setting is being protected
It holds in the steel ball slot 21 of frame 2, retainer 2 is clipped between Upper gasket 1 and lower gasket 3, and steel ball and Upper gasket 1 and lower gasket 3 are real
Existing point contact；The aperture of Upper gasket 1 is less than the aperture of lower gasket 3, and shaft is mounted in the hole of Upper gasket 1；When work, Upper gasket
1 rotates together with shaft.
As shown in Fig. 2, the retainer 2 of the utility model is in bowl face shape, the steel ball slot 21 of retainer 2 is evenly distributed on guarantor
On the inclined-plane for holding frame 2（It could also say that respectively in bowl face）.Since retainer 2 is fabricated to bowl face shape, retainer 2 can carry
Steel ball it is more, correspondingly, the power smaller that each steel ball is born when in use, bearing pitting corrosion resistant performance are stronger.And it is in bowl face
The retainer 2 of shape can make steel ball obtain more stable support, and steel ball is not in shift phenomenon, and each steel ball stress is identical, this
Sample bearing pitting corrosion resistant performance is also stronger.
Upper gasket 1 has a upper pad portion 12, the periphery in upper pad portion 12 be with the matched upper cambered surface raceway 120 of steel ball, and
3 raised underlay portion 30 of lower gasket, the periphery in underlay portion 30 are and the matched lower camber side raceway of steel ball 300.Steel ball
It is located between cambered surface raceway 120 and lower camber side raceway 300, due to 30 protrusion of underlay portion of lower gasket 3, can prevent
Retainer 2 is contacted with lower gasket 3, to ensure bearing performance.There is Upper gasket 1 middle part 11, the diameter of middle part 11 to be more than
The diameter in upper pad portion 12, there are one spaces with the tool of underlay portion 12 for such middle part 11, are equally also possible to prevent retainer 2 and keep up with pad
Piece 1 contacts, to ensure bearing performance.
In extreme environments, retainer 2 is possible to contact with Upper gasket 1 or lower gasket 3, in order in such case
Lower to reduce mutual frictional force, 1 middle part 11 of Upper gasket of the utility model is contacted close to the bottom surface of outer circle 110 for line
Face, and lower gasket 3 is line contact surface close to the top surface of inner circle 31.Line contact surface is that a circle astragal shape is distributed in one kind on the surface
The face of protrusion.Even if retainer is contacted with Upper gasket 1 or lower gasket 3, however it is line contact, frictional force also smaller, to
Ensure that bearing can also bear work in extreme environments.
Finally it is worth mentioning that in order to enable retainer 2 to bear bigger pressure, the utility model phase on retainer 2
It is equipped with reinforcing rib 22 between adjacent two ball slots 21.Reinforcing rib 22 not only strengthens the intensity of retainer 2, moreover it is possible to deepen steel ball
The depth of slot 21, deeper steel ball slot 21 can guarantee that steel ball is stably maintained in retainer 2, and steel ball is less prone to offset
Or vibration.
