Abstract
The present utility model relates to a bearing, concretely relates to a cylindrical roller bearing comprising an outer lane, an inner lane and a roller. The outer lane has a blocking rim, the working surface of the blocking rim is an inclined surface with an inclination angle alpha of 6' to 42', the end-face of the roller is an end-face of ball, the distance between a contact point of the blocking rim and end-face of ball and a rolling way does not exceed two thirds of the height of the blocking rim. The blocking rim has an inclination angle of alpha, and point contact between the blocking rim and the end-face of ball of the roller forms effective lubricating flow body. The cylindrical roller bearing has small friction, long service life and convenient processing and improves the axial bearing capacity of the bearing greatly.
Description
Technical field
The utility model relates to a kind of bearing, specifically is a kind of roller bearing.
Background technique
Cylindrical roller and raceway are line contact bearing, and load carrying capacity is big, and radially bearing capacity is big, are suitable for bearing heavy load and impact load; Friction factor is little, the limit speed height; Inner ring and outer ring are separable, are installed on convenient disassembly.But the axial carrying capacity of roller bearing is low, has also limited its application area, and it is significant to the usability and the life-span of modern machinery and equipment therefore to improve the roller bearing axial carrying capacity.The thrust load of roller bearing relies on rib structure and rib to bear with contacting of roller end face, made corresponding improvement abroad for this reason, rib has certain angle of inclination, rib contacts with the roller section also improvement, compare contacting between the flat rib of state's inner bearing and plane roller, can effectively form lubricating fluid, and improve axial carrying capacity.But external improvement project centre rib structure difficulty of processing is big, is difficult to accomplish processing in enormous quantities, be difficult to guarantee precision stability simultaneously, detects also relatively difficulty, to measuring requirement than higher, so be difficult to obtain promote.
The model utility content
The technical problems to be solved in the utility model is: problems such as low in order to overcome existing roller bearing axial carrying capacity, friction is big, and working life is short, it is a kind of easy to process that the utility model provides, the roller bearing that axial carrying capacity is big.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of roller bearing, comprise outer ring, inner ring and roller, outer astragal rib, the working surface of rib is the inclined-plane, the inclination alpha on inclined-plane is 6 '～42 ', the end face of roller is the pommel face, and the point of contact of rib and pommel face is no more than 2/3 of rib height from the distance of roller surface.
The beneficial effects of the utility model are: its rib has inclination alpha, and rib contacts with the pommel millet cake of roller, can form effective lubricating fluid, and it is little to rub, and long service life is easy to process, has improved the axial carrying capacity of bearing greatly.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Wherein: 1. outer ring, 11. ribs, 2. roller, 21. pommel faces.
Embodiment
As shown in Figure 1, a kind of roller bearing, comprise outer ring 1, inner ring and roller 2, outer ring 1 band rib 11, the working surface of rib 11 is the inclined-plane, the inclination alpha on inclined-plane is 6 '～42 ', the end face of roller 2 is a pommel face 21, rib 11 is no more than 2/3 of rib 11 height with the point of contact of pommel face 21 from the distance of roller surface.
The working surface inclined-plane of the rib 11 of this bearing, the inclination alpha on inclined-plane be 6 '～42 ', contact with 21 in the pommel face of roller 2, can form effective lubricating fluid on the one hand, reduce friction, add the long life, improve axial bearing capacity, processing is also more convenient on the other hand.
Claims (1)
1. roller bearing, comprise outer ring (1), inner ring and roller (2), outer ring (1) band rib (11), it is characterized in that: the working surface of rib (11) is the inclined-plane, the inclination alpha on inclined-plane is 6 '～42 ', the end face of roller (2) is pommel face (21), and rib (11) is no more than 2/3 of rib (11) height with the point of contact of pommel face (21) from the distance of roller surface.
