The roller bearing is a rolling bearing using short cylindrical, conical or waist drum shaped rollers as rolling bodies. Mainly have entad short cylindrical roller, biserial entad spherical roller, tapered roller and thrust roller class of structural style, present bearing has easily to hide the ash, and along with the use of bearing, more and more dust can be piled up to the bearing inside, gets into in the outer lane for the bearing roller is rotatory slow, influences mechanical operation, consequently needs often to carry out abluent problem to the bearing.
Therefore, how to design a tapered roller bearing with good dustproof effect becomes a problem to be solved currently.
Disclosure of Invention
In view of the above, the present invention provides a retainer for adjusting the position of balls, stabilizing the rotational speed of a bearing, and preventing the bearing from locking up by reducing wear.
In order to solve the technical problem, the technical scheme of the utility model is that:
a tapered roller bearing with good dustproof effect comprises an outer ring, an inner ring arranged in the outer ring, a roller retainer arranged between the outer ring and the inner ring, and rollers arranged in the retainer; the roller retainer is in including the support body that the slope set up, the setting is in conical groove in the support body, and set up the support body is outside on one side, and through the draw-in groove that the annular array distributes, the dust ring fixed with the roller retainer is still installed to one side of outer lane and inner circle, the dust ring is the elastic rubber ring, the dust ring still is provided with a plurality of tilt up on the side of roller retainer, corresponds the fixture block of gomphosis with the draw-in groove.
Preferably, the outer diameter part of the dust ring extends to the lower part of the outer ring and is in clearance fit with the outer ring, and the inner diameter part of the dust ring extends to the inner ring and is in clearance fit with the inner ring.
Preferably, the clamping blocks are distributed in an annular array and are integrally formed with the dust ring.
Preferably, one end of the outer ring extends outwards, and an outer ring slideway is arranged on the side surface of the outer ring facing the roller retainer and is recessed inwards.
Preferably, the side surface of the inner ring facing the roller cage is provided with an inner ring slideway which is inwards recessed.
Preferably, the other side of the inner ring opposite to the dust ring is also provided with a flange, and the flange is favorable for supporting the roller cage.
The utility model discloses technical effect mainly embodies in following aspect: can prevent through the dust ring that the dust from entering into inside by the clearance between outer lane and the inner circle, influence the behavior of roller in the roller holder to the dust ring is for having elastic rubber ring, can make fixture block and draw-in groove cooperation card hold stably through elastic dynamics, and difficult pine takes off, consequently, this tapered roller bearing reasonable in design, through avoiding the dust to get into the bearing and reduce the washing number of times of bearing.
Drawings
FIG. 1 is a schematic diagram of a tapered roller bearing with a good dustproof effect;
fig. 2 is a cross-sectional view of fig. 1.
Detailed Description
The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings, so that the technical solution of the present invention can be more easily understood and grasped.
In the present embodiment, it should be understood that the terms "middle", "upper", "lower", "top", "right side", "left end", "above", "back", "middle", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description of the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
In the present embodiment, if the connection or fixing manner between the components is not specifically described, the connection or fixing manner may be a bolt fixing manner, a pin connecting manner, or the like, which is commonly used in the prior art, and therefore, details thereof are not described in the present embodiment.
Examples
A tapered roller bearing with good dustproof effect is shown in figures 1-2 and comprises an outer ring 1, an inner ring 2 arranged inside the outer ring 1, a roller retainer 3 arranged between the outer ring 1 and the inner ring 2 and rollers 4 arranged in the retainer 3; and a dustproof ring 5 fixed with the roller retainer 3 is further installed on one side of the outer ring 1 and one side of the inner ring 2.
The dust ring 5 is an elastic rubber ring, and a plurality of clamping blocks 51 which are inclined upwards and correspondingly embedded with the clamping grooves 33 are further arranged on one side surface of the dust ring 5 facing the roller retainer 3. The outer diameter part of the dust ring 5 extends to the lower part of the outer ring 1 and is in clearance fit with the outer ring 1, the inner diameter part of the dust ring 5 extends to the inner ring 2 and is in clearance fit with the inner ring 2, and the dust ring 5 does not influence the rotating effect of the tapered roller bearing in the rolling process.
The fixture blocks 51 are distributed in an annular array and integrally formed with the dust ring 5, and the number of the fixture blocks 51 is the same as that of the fixture grooves 33.
The dismounting mode of the dust ring 5 is as follows:
when the dust ring 5 is installed, the dust ring 5 is elastic, so that the clamping blocks 51 can be bent to correspond to the clamping grooves 33 one by one and be embedded, the dust ring 5 is completely installed on the roller retainer 3, and the clamping blocks 51 are inclined upwards and correspond to the inclined clamping grooves 33, so that the dust ring 5 is not easy to loosen under the tension action of the dust ring 5.
When the dust ring 5 is disassembled, the dust ring 5 is elastic, so that the clamping blocks 51 can be separated from the clamping grooves 33 one by bending the dust ring 5, the dust ring 5 is completely separated from the roller retainer 3, and the disassembly is completed.
The utility model discloses technical effect mainly embodies in following aspect: can prevent through the dust ring that the dust from entering into inside by the clearance between outer lane and the inner circle, influence the behavior of roller in the roller holder to the dust ring is for having elastic rubber ring, can make fixture block and draw-in groove cooperation card hold stably through elastic dynamics, and difficult pine takes off, consequently, this tapered roller bearing reasonable in design, through avoiding the dust to get into the bearing and reduce the washing number of times of bearing.
Of course, the above is only a typical example of the present invention, and besides, the present invention can also have other various specific embodiments, and all technical solutions adopting equivalent replacement or equivalent transformation are all within the scope of the present invention as claimed.
