Abstract
The invention discloses a rolling bearing without a retainer. The rolling bearing without a retaine comprises a large outer ring, an inner thread, a continuous ball, a roller rail, a small outer ring, an outer thread, an oil hole, a ball and a roller, an inner ring, a single ball, and a hole rail which is half of the shape of the roller. The rolling bearing has the beneficial effects that the retainer is not used; the production process is simplified; the production cost is reduced; the radial force resistance and the axial force resistance are improved; a sealed dustproof effect of the bearing is enhanced; and the service life of the rolling bearing is prolonged by multiple times.
Description
Technical field the present invention relates to a kind of rolling bearing of using on the various machinery.
Background technique the objective of the invention is: a kind of rolling bearing that does not have retainer is provided.Technological scheme of the present invention is: the external diameter of interior ring (4) is processed into several uniform single balls, half hole track (4b) of roller shape, and and ball, roller (3) leave a certain amount of rolling gap, outer shroud is processed into one heart large outer shroud (1) and little outer shroud (2) with internal diameter.The external diameter of interior ring (4) is processed into half continuous ball, roller track (4c) of ball, roller shape, and leaves and ball, the certain rolling gap of roller (3).Interior straight mouth (1c) internal sealing plug (1d) of large outer shroud (1) and the external diameter of half internal sealing plug (1g) are wanted large two millimeter than continuous ball, roller track (1f) maximum outside diameter.Interior straight mouthful (1c) of large outer shroud (1) and outer straight mouthful (2c) of little outer shroud (2) are processed into concentric interference stationary fit; The internal sealing plug (1d) of large outer shroud (1) and the external sealing plug (2a) of little outer shroud (2) are processed into the same pitch of nominal diameter; Half internal sealing plug (1g) of large outer shroud (1) and half external sealing plug (2d) of little outer shroud (2) are processed into the same pitch of nominal diameter.Large outer shroud (1), the internal diameter of little outer shroud (2) and the external diameter of interior ring (4) are processed into one heart movingly; Large outer shroud (1) be processed with the maximum diameter of continuous ball, roller track (1f) and fill ball, roller mouth (1a) maximum diameter is identical; The outer ladder mouth (1b) of large outer shroud (1) and the interior ladder mouth (4a) of interior ring (4) are processed into one heart movingly.
The invention has the beneficial effects as follows: omitted retainer, simplified production technology, reduced cost of production, promoted that rolling bearing is anti-radially, the ability of axial force, increased the sealing and dustproof effect of bearing, prolonged several times rolling bearing service life.
Description of drawings: accompanying drawing 1 is the sectional view that is processed with the ball rolling bearing of internal sealing plug (1d), external sealing plug (2a), single ball, half hole track (4b) of roller shape; Accompanying drawing 2 is A-A sectional views of accompanying drawing 1; Accompanying drawing 3 is to be processed with interior straight mouthful (1c), outer straight mouthful (2c), the continuously sectional view of the cylindrical roller rolling bearing of ball, roller track (4c); Accompanying drawing 4 is B-B sectional views of accompanying drawing 3; Accompanying drawing 5 is the sectional views that are processed with the barrel shaped roller rolling bearing of half internal sealing plug (1g), half external sealing plug (2d); Accompanying drawing 6 is c-c sectional views of accompanying drawing 5.
Part sequence number is as follows in the accompanying drawing; Large outer shroud (1), dress ball, roller mouth (1a), outer ladder mouth (1b), interior straight mouthful (1c), internal sealing plug (1d), continuous ball, roller track (1f), half internal sealing plug (1g); Little outer shroud (2), external sealing plug (2a), oilhole (2b), outer straight mouthful (2c), half external sealing plug (2d); Ball, roller (3), ball (3a), cylindrical roller (3b), barrel shaped roller (3c); Interior ring (4), interior ladder mouth (4a), single ball, half hole track (4b) of roller shape, continuously ball, roller track (4c).
Embodiment: the present invention such as accompanying drawing 1, in 2 illustrated embodiments, single ball of the interior ring (4) that processes, all load onto the ball (3a) that wipes lubricated butter in half hole track (4b) of roller shape, after being loaded on large outer shroud (1), behind one of the suitable place processing of little outer shroud (2) or several oilholes (2b), be screwedly mounted on the internal sealing plug (1d) of large outer shroud (1) and just formed a complete ball rolling bearing, during use the little outer shroud (2) that oilhole (2b) arranged be placed on bearing housing in mouthful, in case lubricant oil leaks outside.
In the present invention such as accompanying drawing 3.4 illustrated embodiments, after all loading onto the cylindrical roller (3b) that wipes lubricated butter in the continuous ball of the interior ring (4) that processes, the roller track (4c) and leaving ball, roller (3) the diameter rolling gap about half, again after about 150 ℃ of large outer shroud (1) heating, be processed with the little outer shroud (2) of or several oilholes (2b) on press-fiting again while hot, just be assembled into a complete cylindrical roller rolling bearing.During use the little outer shroud (2) that oilhole (2b) arranged be placed on bearing housing in mouthful, in case lubricant oil leaks outside.
In accompanying drawing 5.6 illustrated embodiments of the present invention, the continuous ball of the interior ring (4) that processes, all load onto the barrel shaped roller (3c) that wipes lubricated butter in the roller track (4c) and leave ball, behind the rolling gap of roller (3) diameter about half, behind one of the suitable place processing of little outer shroud (2) or several oilholes (2b), be screwedly mounted on half internal sealing plug (1g) of large outer shroud (1) and just formed a complete barrel shaped roller rolling bearing, during use the little outer shroud (2) that oilhole (2b) arranged be placed on bearing housing in mouthful, in case lubricant oil leaks outside.
