Abstract
The utility model discloses a drawn cup radial and thrust needle roller combination bearing. The drawn cup radial and thrust needle roller combination bearing comprises a drawn cup radial needle roller bearing and a thrust needle roller bearing assembly, wherein the drawn cup radial needle roller bearing comprises a drawn cup, a plurality of radial needle rollers and radial cages; the plurality of radial needle rollers are installed and connected on the radial cages and are arranged in the drawn cup; radially outward extension sections are arranged at one end of the drawn cup and form inward covered edges; the thrust needle roller bearing assembly comprises a plurality of thrust needle rollers, thrust washers and thrust cages; the two ends of the thrust washers and the thrust cages are installed in the covered edges; the plurality of thrust needle rollers are installed and connected on the thrust cages. The drawn cup radial and thrust needle roller combination bearing has the effects of changing the traditional structure of respective installation of the two kinds of bearings, reducing the processing and installation costs and prolonging the service life.
Description
Technical field
The utility model relates to the centripetal and thrust needle roller combination bearing in a kind of Novel punching outer ring, is applicable to space less and bear the mechanism of radial and axial load simultaneously.
Background technique
In the time of traditional, bear the mechanism of radial and axial load, the in the situation that of limited space, when type selecting, conventionally use a set of punching press needle bearing, then on mechanism's end face, process a positioning step, on positioning step, use a plain thrust bearing, adopt two kinds of bearings to increase installation and processing cost, when still displacement appears in this axis of no-feathering, plain thrust bearing easily comes off and causes stuck phenomenon, the integrity of having destroyed mechanism causes mechanism to damage, and has reduced working life.
Summary of the invention
The purpose of this utility model is to provide a kind of two kinds of structures that bearing is installed respectively of tradition that change, and has reduced processing and installation cost, improve the drawn cup in working life centripetal with thrust needle roller combination bearing.
In order to achieve the above object, the technical solution of the utility model is: a kind of drawn cup centripetal with thrust needle roller combination bearing, comprise the centripetal needle bearing of drawn cup and needle roller thrust bearing assembly, the centripetal needle bearing of drawn cup comprises drawn cup, a plurality of centripetal needle rollers and centripetal retainer, a plurality of centripetal needle rollers are installed on centripetal retainer, and be positioned at drawn cup, drawn cup one end is provided with radially outside extension, and form inside bound edge, needle roller thrust bearing assembly comprises a plurality of thrust needle rollers, Thurst washer and thrust retainer, the two ends of Thurst washer and thrust retainer are contained in bound edge, a plurality of thrust needle rollers and the load of thrust retainer.
Adopt after said structure, owing to adopting the centripetal needle bearing of drawn cup together with needle roller thrust bearing assembled, by drawn cup one end, be provided with radially outside extension, and the mode that forms inside bound edge is combined by two kinds of bearing pack the phenomenon of having avoided mutual disengaging, reduced end face positioning step, once mounting just can meet use simultaneously, has reduced installation and processing cost, improve bearing working life, also improved installation efficiency simultaneously.
Accompanying drawing explanation
Fig. 1 is structure sectional view of the present utility model;
Fig. 2 is use phase diagram of the present utility model.
Embodiment
The example providing below in conjunction with accompanying drawing is described in further detail the utility model.
Referring to Fig. 1, shown in 2, a kind of drawn cup centripetal with thrust needle roller combination bearing, comprise the centripetal needle bearing 1 of drawn cup and needle roller thrust bearing assembly 2, the centripetal needle bearing 1 of drawn cup comprises drawn cup 1-1, a plurality of centripetal needle roller 1-2 and centripetal retainer 1-3, a plurality of centripetal needle roller 1-2 are installed on centripetal retainer 1-3, and be positioned at drawn cup 1-1, drawn cup 1-1 one end is provided with radially outside extension 1-1-1, and form inside bound edge 1-1-2, needle roller thrust bearing assembly 2 comprises a plurality of thrust needle roller 2-1, Thurst washer 2-2 and thrust retainer 2-3, the two ends of Thurst washer 2-2 and thrust retainer 2-3 are contained in bound edge 1-1-2, a plurality of thrust needle roller 2-1 and thrust retainer 2-3 load.
Shown in Figure 2, when the utility model is installed and uses, the utility model is sleeved on Step Shaft 3, centripetal needle roller 1-2 rolls and coordinates with Step Shaft 3 peripheries, thrust needle roller 2-1 rolls and coordinates with the step surface 3-1 of Step Shaft 3, and the periphery that is contained in drawn cup 1-1 of sleeve 4 interference fit of mesopore 4-1 will be provided with, one end of the drawn cup 1-1 of the centripetal needle bearing 1 of drawn cup of the present utility model extends radially outward and forms extension 1-1-1, and form inside bound edge 1-1-2, this bound edge 1-1-2 can limit thrust needle bearing assembly 2 move radially and axially come off, and needle roller thrust bearing assembly 2 can flexible rotating.The utility model is owing to adopting the centripetal needle bearing 1 of drawn cup and needle roller thrust bearing assembly 2 to be assembled together, by drawn cup 1-1 one end, be provided with radially outside extension, and the mode that forms inside bound edge is combined by two kinds of bearing pack the phenomenon of having avoided mutual disengaging, reduced end face positioning step simultaneously, once mounting just can meet use, reduce installation and processing cost, improved bearing working life, also improved installation efficiency simultaneously.
