Description
Technical field
The utility model relates to the centripetal and needle roller thrust 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
The mechanism of radial and axial load is born while traditional, when limited space, usually a set of punching press needle bearing is used when type selecting, then on mechanism's end face, a positioning step is processed, positioning step uses a plain thrust bearing, adopts two kinds of bearings to add and install and processing cost, but when displacement appears in this axis of no-feathering, plain thrust bearing easily comes off and causes stuck phenomenon, the integrity destroying mechanism causes mechanism to damage, and reduces working life.
Summary of the invention
The purpose of this utility model is to provide a kind of structure changing tradition two kinds of bearings and install respectively, reduces processing and installation cost, improves the drawn cup in working life centripetal with needle roller thrust combination bearing.
In order to achieve the above object, the technical solution of the utility model is: a kind of drawn cup is centripetal with needle roller thrust combination bearing, comprise drawn cup radial needle roller bearing and needle roller thrust bearing assembly, drawn cup radial needle roller bearing comprises drawn cup, multiple radial needle roller and centripetal retainer, multiple radial needle roller is installed on centripetal retainer, and be positioned at drawn cup, drawn cup one end is provided with extension radially, the maximum diameter place of described extension is provided with radial bound edge, needle roller thrust bearing assembly comprises multiple needle roller thrust, Thurst washer and thrust retainer, the two ends of Thurst washer and thrust retainer are contained in bound edge, multiple needle roller thrust and the load of thrust retainer, also comprise case, described case comprises the case rib and case urceolus that connect as one, the inwall of case urceolus is coated on the periphery wall of drawn cup bound edge, and the periphery wall of case urceolus and bound edge is riveted, the internal diameter of described case rib is less than the external diameter of thrust retainer.
After adopting said structure, due to adopt casing structure by drawn cup radial needle roller bearing together with needle roller thrust bearing assembled, wherein drawn cup one end is provided with extension radially, the maximum diameter place of described extension is provided with radial bound edge, described case comprises the case rib and case urceolus that connect as one, the inwall of case urceolus is coated on the periphery wall of drawn cup bound edge, and the periphery wall of case urceolus and bound edge is riveted, the internal diameter of described case rib is less than the external diameter of thrust retainer.With such form two kinds of bearing pack are combined and not only avoid mutual disengaging but also achieve in certain space relative to rotating.What thrust retainer was complete is included in drawn cup extension, bound edge and case rib, thrust retainer is prevented to come off to greatest extent, decrease end face positioning step simultaneously, once mounting just can meet use, reduce installation and processing cost, improve bearing working life, also improve installation efficiency simultaneously.
