Abstract
The invention provides a thrust articulated bearing with a net-shaped roller path, aiming at the defects of poor lubrication of inner and outer roller paths of traditional thrust articulated bearings matched with cargo trucks. The thrust articulated bearing with a net-shaped roller path comprises an inner ring and an outer ring, wherein a longitudinal lubricating groove and a transverse lubricating groove are embedded in the roller path of the outer ring; and the outer ring and the inner ring are in a direct contact and rotate through a lubricating oil film made of lubricating grease in the lubricating grooves. The structure thoroughly overcomes the defects of dry friction of a bearing ring, ring damage and short service life of the bearing in an original structure, and the service life of the bearing with the structure can be improved by about 5 times.
Description
Technical field
The invention belongs to technical field of bearings, relate to a kind of supporting thrust articulated bearing of truck that is.
Background technique
Be the supporting thrust articulated bearing of truck at present, applying working condition is abominable, should not often dismantle, thereby should guarantee good lubricating, traditional design method, raceway face adopt spherical smooth surface, because no rolling element, inside and outside raceway directly contacts, and produces defectives such as insufficient lubrication.
Summary of the invention
At above defective, the present invention proposes a kind of thrust articulated bearing with the net form raceway.On outer ring raceway, design multiple row lubrication groove in length and breadth, guarantee bearing good lubrication in use.
Technological scheme of the present invention is: the thrust articulated bearing of band net form raceway, comprise outer ring 1 and inner ring 2, and be embedded with lubrication groove 3 on 1 raceway of outer ring, outer ring 1 directly contacts with inner ring 2, and the lubricant film that forms by the lubricating grease in the lubrication groove 3 is rotated.
Described lubrication groove 3 comprises radial groove 4 and axial groove 5.
The invention has the beneficial effects as follows: thoroughly overcome the dry friction of original structure middle (center) bearing lasso, ring damage and caused the short defective of bearing life, can improve nearly 5 times the working life of this airframe bearing.
Description of drawings
Below in conjunction with the drawings and the specific embodiments the present invention is elaborated:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is an outer ring raceway schematic representation of the present invention.
Among the figure, 1, the outer ring, 2, inner ring, 3, lubrication groove, 4, radial groove, 5, axial groove.
Embodiment
As shown in Figure 1, the present invention includes outer ring 1 and inner ring 2, be embedded with longitudinal and transverse lubrication groove 3 on 1 raceway of outer ring, as Fig. 2,4 places are radial groove; 5 places are axial groove, axle, the longitudinal and transverse arrangement of radial groove, be embedded on the outer ring raceway, at sliding contact surface place coating molybdenum disulfide, molybdenum disulfide penetrates in the net form lubrication groove, crisscross lubricated, when inside and outside circle raceway is rotated, make and lubricate fully, guarantee bearing good lubrication in use, satisfy the requirement of product usability, improve bearing working life.
Claims (2)
1. be with the thrust articulated bearing of net form raceway, comprise outer ring (1) and inner ring (2), it is characterized in that, be embedded with lubrication groove (3) on the raceway of outer ring (1), outer ring (1) directly contacts with inner ring (2), and the lubricant film that forms by the lubricating grease in the lubrication groove (3) is rotated.
2. the thrust articulated bearing of band net form raceway according to claim 1 is characterized in that, described lubrication groove (3) comprises radial groove (4) and axial groove (5).
