Abstract
The utility model discloses a bearing which comprises an outer ring, an inner ring and a rolling part arranged between the outer ring and the inner ring, wherein the inner ring and the outer ring can rotate relatively through the rolling part; a shaft hole for the insertion of a shaft body is formed in the inner ring; a shock absorption ring is mounted on the shaft hole and clings to the inner wall of the shaft hole. According to the bearing, the shock absorption ring is arranged at the shaft hole of the inner ring, so that the wear between the inner ring and the shaft body due to rotation of the inner ring and vibration of mechanical equipment is effectively reduced, and the service life of the bearing is prolonged; in addition, seal rings are arranged on two end surfaces of the outer ring and the inner ring to seal a mounting groove, so that the consumption of lubricating oil can be effectively reduced, the lubricating oil is prevented from being volatilized, and the problem that the operation of the bearing is affected due to entry of dust into the mounting groove is avoided.
Description
Technical field:
The utility model design field of mechanical technique, refers in particular to a kind of bearing.
Background technique:
Bearing is in mechanical transmission course, to work the parts of fixing and reducing load friction factor.Also can say, when other parts produce relative movement each other on axle, be used for reducing the fixing parts of friction factor and retainer shaft central position in power transmission process.Bearing is a kind of very important component in contemporary machinery, and its precision, performance, life and reliability play conclusive effect to the precision of main frame, performance, life and reliability.Its major function is supported mechanical solid of rotation, the mechanical load friction factor in order to reduction equipment in transmission process.Press the difference of motor element frictional property, bearing can be divided into rolling bearing and sliding bearing two classes.Generally speaking, bearing there is outer ring, inner ring and be arranged at outer ring and inner ring between roll piece, an axis body is installed on inner ring, by this axis body, rotating shaft is connected in machinery.In prior art, no matter be the bearing of which kind of frictional property, all between axis body, to be installed in the axis hole of bearing, when bearing rotates, because high speed rotating can make to produce and rub between axis body and bearing, and due to the vibrations of machinery, can make to produce wearing and tearing between axis body and bearing, shorten the life-span of bearing.
In order to address the above problem, the utility model arranges with bump protection ring in the axis hole place of bearing, has reduced the wearing and tearing between axis body and bearing, increases bearing life.
Model utility content:
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of bearing is provided.
In order to solve the problems of the technologies described above, the utility model has adopted following technical proposals: a kind of bearing, comprise: outer ring, inner ring and be arranged at the roll piece between outer ring, inner ring, between described inner ring and outer ring, by roll piece, can mutually rotate, on inner ring, form for the interspersed axis hole of axis body, bump protection ring is installed on axis hole, and bump protection ring is close to shaft hole inner wall.
Furthermore, in technique scheme, described bump protection ring is the hollow cylindrical colloid with high-strength buffering shock-absorbing shock resistance, and bump protection ring is close to the inwall of the axis hole of inner ring.
Furthermore, in technique scheme, described bump protection ring is the hollow cylindrical colloid that silica gel material is made, and bump protection ring height equals inner ring height.
Furthermore, in technique scheme, between described outer ring and inner ring, form mounting groove, roll piece is installed in this mounting groove, and in outer ring and inner ring both ends of the surface, seal ring is installed, and makes mounting groove sealing.
Furthermore, in technique scheme, described roll piece is ball.
Furthermore, in technique scheme, described axis body is screw rod, is provided with screw thread on screw rod; Described screw rod is fixed in axis hole and inner ring interlock.
Furthermore, in technique scheme, described axis body is an axostylus axostyle, and described axostylus axostyle is fixed in axis hole and inner ring interlock.
Furthermore, in technique scheme, its inwall of described bump protection ring is provided with antiskid thread.
Adopt after technique scheme, the utility model has following beneficial effect compared with prior art: the utility model is provided with bump protection ring in the axis hole place of inner ring, effectively reduce because inner ring rotates and mechanical equipment vibration makes the wearing and tearing that produce between inner ring and axis body, increase bearing life.In addition, in the both ends of the surface of outer ring and inner ring, be provided with seal ring, mounting groove is sealed, can effectively reduce the consumption of lubricant oil, prevent the volatilization of lubricant oil and prevent that dust from entering in mounting groove, affects the running of bearing.
Accompanying drawing explanation:
Fig. 1 is plan view of the present utility model;
Fig. 2 is axial sectional view of the present utility model;
Fig. 3 is the assembled sectional view of the utility model bearing and axis body.
Description of reference numerals:
1 outer ring 11 mounting groove 12 seal rings
2 inner ring 21 axis holes
3 bump protection rings
4 axis bodies
5 balls
Embodiment:
Below in conjunction with specific embodiments and the drawings, the utility model is further illustrated.
See shown in Fig. 1-3, a kind of bearing, comprise: outer ring 1, inner ring 2 and be arranged at the roll piece between outer ring 1, inner ring 2,1 of described inner ring 2 and outer ring can be rotated mutually by roll piece, on inner ring 2, form for the interspersed axis hole 21 of axis body 4, bump protection ring 3 is installed on axis hole 21, and bump protection ring 3 is close to axis hole 21 inwalls.
Particularly, between described outer ring 1 and inner ring 2, form mounting groove 11, roll piece is installed in this mounting groove 11, and roll piece is ball 5, and ball 5 is arranged in mounting groove 11 equably, between outer ring 1 and inner ring 2, relies on ball 5 to relatively rotate.In outer ring 1 and inner ring 2 both ends of the surface, seal ring 12 is installed, seal ring 12 makes mounting groove 11 sealings, in mounting groove 11, can pack lubricant oil into, can effectively reduce owing to rotating the friction of generation and the heat of generation, also can prevent that dust and other impurities from entering in mounting groove, affect the running of bearing simultaneously.
Described bump protection ring 3 adopts the material of high-strength buffering shock-absorbing shock resistance to make, the hollow cylindrical colloid of the bump protection ring 3 in the present embodiment for adopting silica gel material to make, and bump protection ring 3 highly equals inner ring 2 height, and bump protection ring 3 is close to the inwall of the axis hole of inner ring 2.Described axis body 4 is screw rod, on screw rod, be provided with screw thread, screw rod is fixed in axis hole 21, screw rod is arranged on bump protection ring 3, and because bump protection ring 3 friction factor are large, between screw rod and bump protection ring 3, can not produce relative rotation, when inner ring 2 rotates, screw rod and inner ring 2 interlocks, bump protection ring 3 can play antihunt action effectively, prevents screw rod wearing and tearing mutually between inner ring 2.
In addition, described axis body 4 also can be an axostylus axostyle, at bump protection ring 3 its inwalls, is provided with antiskid thread, prevents bump protection ring 3 and axostylus axostyle relative sliding, and axostylus axostyle is fixed in axis hole 21 and inner ring 2 interlocks.
Certainly, the foregoing is only specific embodiment of the utility model, be not to limit the utility model practical range, all according to equivalence variation or modification that described in the utility model claim, structure, feature and principle are done, all should be included in the utility model claim.
