Abstract
The utility model discloses a crescent single-row cylindrical roller bearing which comprises an outer ring, a retainer and rollers, wherein the outer ring and the retainer are both in an arc shape; the retainer is concentrically sleeved in the outer ring; multiple teeth are uniformly distributed on the upper circumference of the end surface at one end of the retainer; and the rollers are uniformly distributed between two teeth. Due to adoption of the structure, since the bearing only needs to swing for certain angle and does not need to rotate for a whole circle in the application occasions such as a plunger pump swinging mechanism, the outer ring and the retainer of the single-row cylindrical roller bearing disclosed by the utility model are in an arc shape, and the using requirements are met; and moreover, compared with the prior art adopting the outer ring and the retainer in a whole-circle structure, the crescent single-row cylindrical roller bearing has the advantage that the production cost is greatly reduced.
Description
Technical field
The utility model relates to a kind of bearing, is specifically related to a kind of single row roller bearing that is applied in the plunger pump swinging mechaism.
Background technique
Single row roller bearing mainly is made of outer ring, retainer, roller, and at present, outer ring and the retainer of existing single row roller bearing are a completely circular structure, but in some applications such as plunger pump swinging mechaism, usually only require that bearing does the swing of several angle, and need not to do the full circle rotation, therefore in these occasions, adopt outer ring and the retainer of completely circular structure, not only cost of production is higher, but also can the flow of plunger pump be impacted.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of and has satisfied the crescent shape single row roller bearing that reduces production costs greatly under the prerequisite of usage requirement.
For achieving the above object, the utility model provides a kind of crescent shape single row roller bearing, comprise outer ring, retainer, roller, described outer ring and retainer are circular shape, the retainer concentric locking collar is loaded in the outer ring, be evenly distributed in several teeth on the one end end face of retainer, described roller is uniformly distributed between two teeth.
The beneficial effects of the utility model are: adopt said structure, because in applications such as plunger pump swinging mechaism, described bearing only need be done the swing of several angle, rotate and need not to do full circle, therefore the outer ring of single row roller bearing provided by the utility model and retainer adopt circular shape, not only satisfy usage requirement, and adopt outer ring and the retainer of completely circular structure compared to existing technology, its cost of production is reduced greatly.
The utility model can be set to further that the left and right sides is symmetrically arranged with two counterbores on the other end end face of described retainer, be equiped with spacing copper post in the counterbore, also be connected with the slotted hole that connects to the retainer outer round surface on the counterbore, described retainer is connected with bearing support by pin, described pin passes bearing support, fix with the spacing copper post in the retainer counterbore, and described pin and retainer slotted hole constitute locating slip and cooperate, and the slip direction between described pin and the retainer slotted hole and the swaying direction of bearing are consistent.
Adopt said structure, can cooperate with the slippage of pin by slotted hole on the retainer, the angle of control bearing swing.

Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is plan view of the present utility model.
Embodiment
As Fig. 1,2, provided a kind of crescent shape single row roller bearing shown in 3, comprise outer ring 1, retainer 2, roller 3, described outer ring 1 and retainer 2 are circular shape, retainer 2 concentric locking collars are loaded in the outer ring 1, be evenly distributed in several teeth 21 on the one end end face of retainer 2, described roller 3 is uniformly distributed between two teeth 21, the left and right sides is symmetrically arranged with two counterbores 22 on the other end end face of described retainer 2, be equiped with spacing copper post 4 in the counterbore 22, also be connected with the slotted hole 23 that connects to retainer 2 outer round surface on the counterbore 22, described retainer 2 is connected with bearing support by pin, described pin passes bearing support, fixing with the spacing copper post 4 in the retainer counterbore 22, and described pin and retainer slotted hole 23 constitutes locating slips and cooperates, and the slip direction between described pin and the retainer slotted hole 23 and the swaying direction of bearing are consistent.
Adopt said structure, because in applications such as plunger pump swinging mechaism, described bearing only need be done the swing of several angle, rotate and need not to do full circle, therefore the outer ring 1 of single row roller bearing provided by the utility model and retainer 2 adopt circular shape, not only satisfy usage requirement, and adopt outer ring and the retainer of completely circular structure compared to existing technology, its cost of production is reduced greatly.
