Embodiment one
As depicted in figs. 1 and 2, pressure bearing is subtracted before providing a kind of automobile in the present embodiment, before described automobile, the bearing base 1 drawing together annular contracted in decompression mechanical axis, outwardly first stop part 2 of described bearing base 1 upper edge radial direction annularly, described bearing base 1 lower edge extends the second stop part 3 along the direction perpendicular to the first stop part 2 to the first stop part 2, namely after subtracting pressure bearing before assembling described automobile, horizontally outward, described second stop part 3 straight up for described first stop part 2; Described second stop part 3 is positioned at described first stop part 2 outside radially.
Embodiment two
Embodiment two subtracts pressure bearing before also providing a kind of automobile, and this embodiment is the further improvement on the basis of embodiment one, and the technological scheme described by embodiment one also belongs to this embodiment, the technological scheme that embodiment one has described no longer repeated description.
Specifically, as depicted in figs. 1 and 2, subtract pressure bearing before providing a kind of automobile in the present embodiment, described front pressure bearing also comprises bearing inner ring 9 and outer race 10; Described bearing inner ring 9 and described outer race 10 form confined space, are filled with lubricant oil and multiple ball 11 in described confined space; Described multiple ball 11 surrounds ring-type, and adjacent described steel column contacts.Further, the quantity of described ball 11 is 60.
As Fig. 3, subtract pressure bearing before of the prior art, outer race 10 cross-section area is less, only wrap up the external surface area of ball 55%, along with bearing rotates, have two phenomenons and produce, first is that ball 11 lifting surface area is little, and second easily outwards overflows for grease.Simultaneously, ball supporting frame 12 is provided with between prior art middle (center) bearing inner ring 9 and outer race 10, because figure middle (center) bearing ball 11 quantity is 36, in continuous firing process, the pressure that single ball 11 bears is larger, the wear extent that each bearing ball 11 rotates is comparatively large, vehicle also can be made to produce abnormal sound when the excessive ball 11 of wear extent rotates.
The present embodiment described before subtract pressure bearing, described bearing inner ring 9 and described outer race 10 form confined space, the cross-section area of described outer race 10 increases, reduce the pressure that every ball 11 is subject to, eliminate ball supporting frame 12 simultaneously, add the quantity of ball 11, ball 11 is made to form ring-type in described bearing inner ring 9 with the confined space of described outer race 10, the single ball 11 of effective minimizing bears pressure further, reduce the wear extent that ball 11 rotates at every turn, increase working life.Meanwhile, described bearing inner ring 9 and described outer race 10 form confined space, and a large amount of lubricant oil can be stored in inside, and the contact wear between ball 11 is reduced.
As Fig. 1 and Fig. 2, in the possibility of the present embodiment, the upper edge of described bearing inner ring 9 and the upper of described outer race 10 are along abutting; The lower edge of described bearing inner ring 9 and the lower of described outer race 10 are along abutting; By mutual abutting, prevent lubricant oil from flowing out from the space between described outer race 10 and bearing inner ring 9.Described bearing inner ring 9 is positioned in described bearing base 1, and described outer race 10 times edges abut with described second stop part 3, and described outer race 10 is fitted with described bearing cap 4; Distance between described first stop part 2 and described second stop part 3 end is not less than the width of described bearing inner ring 9.Described outer race 10 is placed in described bearing base 1 with described bearing inner ring 9, by bearing base 1, prevents the leakage of lubricant oil further.
As Fig. 1 and Fig. 2, in the possibility of the present embodiment, between the upper edge of described bearing inner ring 9 and the upper edge of described outer race 10, be provided with seal ring 7.By described seal ring 7, sealing prevents grease from leaking laterally again.
In the possibility of the present embodiment, the wall thickness of described outer race 10 is 1.58mm.Described outer race 10 not only increases cross-section area, and increase the thickness (being increased to 1.58mm by original thickness 1.01mm) of outer race 10, increase thickness and can increase anti-pressure ability, outer race 10 lifting surface area increases, anti-pressure ability strengthens, and grease not easily outwards overflows.
In sum, subtract pressure bearing before described automobile of the present utility model, eliminate described ball supporting frame, add ball number, the pressure that single ball is subject to reduces, and reduces the pressure wear of ball.Meanwhile, change the shape of described outer race and described bearing inner ring, make the two constitute confined space, described multiple ball is in the lubrication environment of lubricant oil, avoid the frictional loss between ball and ball brought after increasing ball.Further, by changing the shape of described bearing base, and change the described bearing cap matched with it, enable bearing base play the effect of lubrication oil, prevent the leakage of lubricant oil, ensure that described ball is in lubrication environment, reduce the wearing and tearing of ball, make this use novel described before subtract pressure bearing, durable wear, can not abnormal sound be sent.
Last it is noted that above each embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to foregoing embodiments, those of ordinary skill in the art is to be understood that: it still can be modified to the technological scheme described in foregoing embodiments, or carries out equivalent replacement to wherein some or all of technical characteristics; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of each embodiment's technological scheme of the utility model.
