Abstract
The utility model discloses a tapered roller thrust bearing, which comprises a top ring, a bottom ring and a tapered roller, wherein the tapered roller is arranged between the top ring and the bottom ring; the top ring is provided with a through hole, and a lifting nut is arranged in the through hole; the bottom ring is provided with a through hole opposite to the through hole of the top ring; and a bolt matched with the lifting nut penetrates through the through hole in the bottom ring and is in threaded connection with the lifting nut. The bearing is applied to working conditions of low rotating speed and high load, the radial internal clearance of the bearing is adjusted by adjusting the lifting nut, and distribution of different radial load capabilities and axial load capabilities is met by changing the slope gradient of the tapered roller and matching the gradient of a roller way on the top ring, so that the bearing is put into a using environment in an optimal state, the service life of the bearing is greatly prolonged, and fund investment can be saved for users.
Description
Technical field
The utility model relates to a kind of mechanical parts, particularly a kind of tapered roller thrust bearing.
Background technique
In the prior art; In the prior art, bearing is divided into tapered roller bearing, roller bearing and ball bearing, and every kind of bearing has different functions when on equipment, using; As axial load resistant, anti-radial load or anti-axially and connected load radially or sliding friction changed into rolling friction; According to the required type of bearing and the size of size selected of different working environments, roller bearing can only bear radial load, and ball bearing mainly bears radial load; Only bear a part of axial load; Yet in actual use, the axial load ability and the radial load ability of bearing being had various requirements, generally all is to be used with the reply usage requirement through ball bearing and roller bearing; The increase of number of bearings has inevitably caused the increase of fund input amount; And when on heavy machinery, using bearing, even be used the distribution that sometimes also can only satisfy axial load ability and radial load ability reluctantly through roller bearing and ball bearing, this just makes reduce greatly the working life of bearing.
The model utility content
To the deficiency that exists in the existing technology, the purpose of the utility model is to provide a kind of tapered roller thrust bearing that can satisfy various axial load abilities and radial load capability distribution and can significantly prolong bearing life.
The technological scheme of the utility model is achieved in that
Tapered roller thrust bearing; Comprise collar, foundation ring and tapered roller; Said tapered roller is arranged between collar and the foundation ring, and said collar is provided with through hole, in through hole, is provided with hoisting nut; On the foundation ring, have over against the through hole of collar through hole, the through hole that bolt that is complementary with said hoisting nut passes on the foundation ring is threaded with hoisting nut.
Above-mentioned tapered roller thrust bearing, said hoisting nut has the shoulder of carrying, and said carrying takeed on the root edge that is stuck in said collar through hole.
Above-mentioned tapered roller thrust bearing, said circular cone devil is at least 3.
Above-mentioned tapered roller thrust bearing, said cone roller is 22 altogether.
The angle that above-mentioned tapered roller thrust bearing, said tapered roller and said foundation ring form between axially greater than 0 ° less than 90 °.
Above-mentioned tapered roller thrust bearing has grinding undercut at the root of said collar rib.
The beneficial effect of the utility model is: tapered roller thrust bearing is regulated bearing end-play through regulating hoisting nut; Through the inclination that changes tapered roller inclined-plane inclination and cooperate raceway on the collar to satisfy Different Diameter to load carrying capacity and axial load capability distribution; Make bearing put in the Environmental Conditions with the optimum state; So then increased substantially the working life of bearing, can for the user less the input of a large number of fund.
Description of drawings
Fig. 1 is the structural representation of the utility model tapered roller thrust bearing.
Among the figure: the 1-collar, the 2-foundation ring, the 3-tapered roller, the 4-grinding undercut, the 5-hoisting nut, 501-carries shoulder, the 6-rib.
Embodiment
In conjunction with accompanying drawing the utility model is done further explanation:
As shown in Figure 1; Tapered roller thrust bearing comprises collar 1, foundation ring 2 and tapered roller 3, and said cone roller 3 is 22 altogether; Said tapered roller 3 is arranged between collar 1 and the foundation ring 2; The angle that said tapered roller 3 and said foundation ring 2 forms between axially greater than 0 ° less than 90 °, change bearing shaft to anti-load carrying capacity and the radially distribution of anti-load carrying capacity, to reach the performance that in applying working condition, can the most perfectly bring into play tapered roller thrust bearing according to the variation of angle angle.
Said collar 1 is provided with through hole, in through hole, is provided with hoisting nut 5, and said hoisting nut 5 has carries shoulder 501; Saidly carry the root edge that shoulder 501 is stuck in said collar 1 through hole; On foundation ring 2, have over against the through hole of collar through hole, the through hole that bolt that is complementary with said hoisting nut 5 passes on the foundation ring is threaded with hoisting nut 5, has grinding undercut 4 at rib 6 roots of said collar 1; Grinding undercut 4 is in order after the collar completion of processing, to be convenient to withdrawing
The user can regulate the inclination on roller inclined-plane according to actual needs; Change the inclination of the raceway of collar then accordingly; So just can come accurately to regulate according to the requirement to anti-axial load ability of bearing and anti-radial load ability in the Environmental Conditions; So that bearing reaches best user mode; Stopped to occur the one-sided overload of axial load or radial load and the very little situation of load on the other direction, through regulating the play that hoisting nut changes bearing, having guaranteed that tapered roller thrust bearing can also guarantee bearing under the normal situation about using of bearing because operating temperature is too high for a long time can not influence the flexibility that bearing rotates when deforming yet; Can prolong the working life of reasoning tapered roller bearing significantly, for the user has practiced thrift fund.
The foregoing description only be for clearly explain the utility model create done for example, and be not the qualification of the utility model being created embodiment.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all mode of executions.Any conspicuous variation of being extended out within all spirit and principles at the utility model or change still are in the utility model and create among the protection domain of claim.
