Abstract
The utility model discloses a combination bearing, which comprises an upper shaft washer (1), a roller (2), a middle shaft washer (3), a steel ball (5), a seat ring (6) and retainers, wherein the cylindrical roller (2) is arranged between the upper shaft washer (1) and the middle shaft washer (3 ), the cylindrical roller is held in a first retainer (4), steel ball rollers are installed between the middle shaft washer (3) and the seat ring (6), the steel ball rollers are held in a second retainer (7), and the retainers are both closed brass solid retainers. The combination bearing can play a certain of aligning effect under the work state, improves the strength and the wear resistance of the retainers, and increases two times of axial carrying capacity.
Description
Technical field
The present invention relates to a kind of combination bearing that two cover rolling elements are set.
Background technique
Under the prior art, mainly there is the problem of the aspects such as greasy property difference of the big revolution flexibility that influences steel ball of lower, the closed retainer weight of the dynamic and static load of the radial thrust of bearing, bearing in bidirectional angular contact thrust ball bearing, can't satisfy the needs of drilling equipment.
Summary of the invention
The purpose of this invention is to provide and a kind ofly compare with bidirectional angular contact thrust ball bearing, bearing capacity height, greasy property are good, and the bidirectional propulsion combination bearing with certain axial action.
The present invention has constructed a kind of combination bearing, comprises two covers stacked rolling element assembly up and down.Wherein, the superposed first cover rolling element assembly comprises the last blowout patche on top, the middle blowout patche of bottom, and goes up the cylindrical roller between blowout patche and the middle blowout patche; Cylindrical roller limits the position by first retainer.And the second cover rolling element assembly that is arranged in the bottom comprises the seat ring of above-mentioned blowout patche, foot and the steel ball roller between middle blowout patche and the seat ring; Steel ball roller limits the position by second retainer.
Combination bearing of the present invention, its improvement are that the diameter of seat ring is less than the diameter of last blowout patche and middle blowout patche.In addition, select closed brass solid cage for use under first retainer and the second retainer optimal way.Advantage of the present invention is, under the situation of profile size constancy, changes the top of angular contact thrust ball bearing into the thrust cylindrical bearing structure, and the angular contact thrust ball bearing of bottom is constant, in the time of in working order, can play certain aligning effect; Retainer adopts the enclosed construction of brass entity, helps improving the intensity and the wear resistance of retainer, and bidirectional propulsion combination bearing axial carrying capacity of the present invention has improved twice.
Description of drawings
Fig. 1 partly cuts open structural representation for bearing of the present invention.
Embodiment
Combination bearing comprises two covers stacked rolling element assembly up and down as shown in Figure 1.Wherein, the first cover rolling element assembly comprises the last blowout patche 1 on top, the middle blowout patche 3 of bottom, and goes up the cylindrical roller 2 between blowout patche 1 and the middle blowout patche 3; Cylindrical roller 2 limits the position by first retainer 4.The seat ring 6 of blowout patche 3, foot during the second cover rolling element assembly comprises, and the steel ball roller 5 between middle blowout patche 3 and the seat ring 6; Steel ball roller 5 limits the position by second retainer 7.In addition, under the optimal way, the diameter of seat ring 6 is less than the diameter of last blowout patche 1 and middle blowout patche 3.Middle blowout patche 3 and seat ring 6 are correspondingly provided with the raceway of steel ball roller 5 usefulness.And under the optimal way, first retainer 4 and second retainer, 7 preferred closed brass solid cages.
