Abstract
The invention discloses a kind of special-shaped needle bearing, including：Bearing case, bearing inner race and retainer, the retainer is arranged concentrically between bearing case and bearing inner race, the retainer includes the first steel ring, the second steel ring and needle roller, annular space is provided with support bar and is connected between first steel ring and the second steel ring, the support bar both sides are respectively arranged with the arc of clamping needle roller, the needle roller two ends are respectively embedded into the first steel ring and the second steel ring, and the external diameter of the needle roller is tapered into from the middle to both ends.Special-shaped needle bearing of the present invention, especially employ mid diameter big, the small needle roller of two ends diameter, increase single needle roller radial force, simultaneously using the semicircle clamping needle roller on support bar, radial force scope can be effectively increased, needle bearing radial force ability is substantially increased, extends bearing service life.
Description
Technical field
The present invention relates to field of bearings, more particularly to a kind of special-shaped needle bearing.
Background technology
Bearing presses the difference of motor element frictional property, can be divided into rolling bearing and the major class of sliding bearing two, wherein rolling
Bearing is normalized, seriation, but its radial dimension, vibration and noise are larger compared with sliding bearing, and price is also higher.
Needle bearing is a kind of conventional bearing, common needle bearing, due to needle roller diameter is smaller and length relatively
It is long, cause the radial force of bearing weak, needle roller stress is big, easily abrasion or, so that bearing life shortens, be unfavorable for weight
Low operation is carried, the use scope of needle bearing is reduced.
The content of the invention
It is an object of the invention to provide a kind of special-shaped needle bearing, the resistivity of bearing radial forces is lifted, plus
Strong needle roller service life.
For up to this purpose, the present invention uses following technical scheme：
A kind of special-shaped needle bearing, including：Bearing case, bearing inner race and retainer, the retainer are arranged concentrically on bearing
Between shell and bearing inner race, the retainer includes the first steel ring, the second steel ring and needle roller, first steel ring and the second steel
Annular space is provided with support bar and is connected between circle, and the support bar both sides are respectively arranged with the arc of clamping needle roller, institute
State needle roller two ends to be respectively embedded into the first steel ring and the second steel ring, the external diameter of the needle roller is tapered into from the middle to both ends.
In a preferred embodiments of the invention, bearing case and the bearing inner race two ends are located at the first steel ring and the respectively
In two steel rings.
In a preferred embodiments of the invention, the support bar, the first steel ring and the second steel ring are formed in one.
In a preferred embodiments of the invention, first steel ring and the second steel ring inwall are respectively arranged with sealing gasket.
In a preferred embodiments of the invention, the outer wall of the bearing case is provided with the oil filler point being connected with arc.
Beneficial effects of the present invention：Special-shaped needle bearing, especially employs mid diameter greatly, the small needle roller of two ends diameter,
Increase single needle roller radial force, while using the semicircle clamping needle roller on support bar, radial force scope can be effectively increased,
Needle bearing radial force ability is substantially increased, extends bearing service life.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention;
Fig. 2 is Fig. 1 A-A sectional views.
Embodiment
Technical scheme is further illustrated with reference to Fig. 1 and Fig. 2 and by specific embodiment.
A kind of special-shaped needle bearing, including：Bearing case 1, bearing inner race 3 and retainer, the retainer are arranged concentrically
Between bearing case 1 and bearing inner race 3, the retainer includes the first steel ring 21, the second steel ring 22 and needle roller 4, described the
Annular space is provided with support bar 23 and is connected between one steel ring 21 and the second steel ring 22, and the both sides of support bar 23 are set respectively
There is the arc 24 of clamping needle roller 4, the two ends of needle roller 4 are respectively embedded into the first steel ring 21 and the second steel ring 22, the needle roller 4
External diameter taper into from the middle to both ends, the structure of needle roller 4 is combined with arc 24, adds the strong of needle roller radial force
Degree.
Further, bearing case 1 and bearing inner race 3 two ends are located in the first steel ring 21 and the second steel ring 22 respectively,
Formation is tightly connected.
Further, the support bar 23, the first steel ring 21 and the second steel ring 22 are formed in one.
Further, the inwall of 21 and second steel ring of the first steel ring 22 is respectively arranged with sealing gasket 5, improves bearing seal
Property.
Further, the outer wall of the bearing case 1 is provided with the oil filler point being connected with arc 24, improves lubricating ability.
Beneficial effects of the present invention：Special-shaped needle bearing, especially employs mid diameter greatly, the small needle roller of two ends diameter,
Increase single needle roller radial force, while using the semicircle clamping needle roller on support bar, radial force scope can be effectively increased,
Needle bearing radial force ability is substantially increased, extends bearing service life.
Above content is only presently preferred embodiments of the present invention, for one of ordinary skill in the art, according to the present invention's
Thought, will change in specific embodiments and applications, and this specification content should not be construed as to the present invention
Limitation.
