Abstract
The utility model relates to a radial rolling bearing with an outer ring with a slot, which is composed of an inner ring 1, a dustproof cover 2, a rolling body 3, a cage 4 and an outer ring with a slot 5, wherein, the inner ring 1, the dustproof cover 2, the rolling body 3 and the cage 4 all have the same shapes, structures and sizes as that of the parts of various types for radial rolling bearings in national standard, with interchangeability. The utility model is characterized in that the central line in radial direction of the outer surface of the outer ring with a slot 5 is provided with a slot whose width, depth and radius are respectively a, t and r as a working surface; the inner surface of the rolling body, which is contacted with the working surface is in the shape of the surface of a rolling way having the same structures and sizes as the inner surfaces or the outer rings of various types for radial rolling bearings in national standard or having the same structures and sizes as the shapes of the surfaces of rolling ways.
Description
The utility model relates to a kind of radial antifriction bearing, and it is used for sliding door and window, rolling shutter door, industrial automation conveying equipment and makes roller, runner; Make pulley on the lifting appliance.
In the prior art, radial antifriction bearing is national standardization, and it is made up of outer ring, inner ring, rolling element (ball, short garden post roller) and retainer.Rolling element rolls on inside and outside circle raceway during work, retainer separates each other rolling element, it was evenly distributed along garden week, and avoid being in contact with one another of rolling element, and to reduce friction and wear and tear, outer ring and bearing support or support cooperate, inner ring and axle journal cooperate, usually, be that inner ring rotates with axle journal during work, does not change the outer ring.Sometimes can be the outer ring rotation, and inner ring change yet.Also there is the outer ring to open the single-row radial ball bearing (GB227-64) of locking groove in center line one side.When be used for sliding door and window, rolling shutter door, when conveying equipment is made roller, runner, the outer ring directly contacts with U-steel, outer ring rotation, channel-section steel are made guide rail; When using radial antifriction bearing on the lifting appliance, be that rolling bearing is installed on the pulley, the outer ring cooperates with the pulley endoporus, and rolling bearing is play supporting role, and the outer ring rotates with pulley.
The purpose of this utility model is to keep the advantage of prior art, and a kind of improved radial antifriction bearing is provided, and it can replace the pulley in the lifting appliance; It can make the U-steel guide rail of sliding door and window, rolling shutter door, conveying equipment simplify.
The purpose of this utility model is achieved through the following technical solutions; The utility model the same with all types of radial antifriction bearings in the NBS by: inner ring (1), dust cover (2), rolling element (3), retainer (4), outer ring (5) are formed, wherein: inner ring (1), dust cover (2), rolling element (3), retainer (4) all with NBS in shape, the physical dimension of all types of radial antifriction bearings part of the same name just the same, have interchangeability; Only to the outer ring outer surface of all types of radial antifriction bearings in the existing NBS radially midline open width a, degree of depth t, radius r groove as working surface, but it is that the internal surface of all types of radial antifriction bearings outer ring in shape, physical dimension and the NBS of raceway face is that shape, the physical dimension of raceway face is identical with internal surface that rolling element (3) contacts.
The utility model is because the outer ring outer surface that only needs all types of radial antifriction bearings in existing NBS midline fluting radially, or directly the outer ring outer surface is made pulley, so it is simple in structure, when be used for sliding door and window, rolling shutter door, when conveying equipment is made roller, runner, its guide rail channel-section steel can be used angle steel, band steel or Shang word steel instead, steel are saved in weight reduction; When making the lifting appliance pulley, do not reprocess the fit dimension of radial antifriction bearing and pulley, when reducing machining and rigger, simplify the structure, reduce cost, strengthen functional reliability.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
The drawing of accompanying drawing is described as follows: Fig. 1 be sectional drawing, Fig. 2 of outer ring fluting radial antifriction bearing be sectional drawing, Fig. 3 that outer ring fluting radial antifriction bearing directly makes pulley be split at outer surface radial centre lines place, outer ring U type groove, Fig. 4 be split at outer surface radial centre lines place, outer ring V-shaped groove, Fig. 5 be the outer ring outer surface radially midline be split into square groove.
Be described in further detail below in conjunction with accompanying drawing: accompanying drawing 1 the utility model proposes the sectional drawing of outer ring fluting radial antifriction bearing.Among the figure, inner ring (1), dust cover (2), rolling element (3), retainer (4) all with NBS in the shape of all types of radial antifriction bearings part of the same name, physical dimension is just the same, has interchangeability, the outer ring (5) of only slotting is an improvement part of the present utility model, it is in outer ring outer surface midline radially, and the groove that has width a, degree of depth t, radius r is as working surface, and it is square that its flute profile can be accompanying drawing 3U type, accompanying drawing 4V type, accompanying drawing 5.But its internal surface that contacts with rolling element (3) is the raceway face shape, and all types of radial antifriction bearing inner surfaces are that raceway face shape, physical dimension are identical in physical dimension and the NBS.
Accompanying drawing 2 is another examples that the utility model is implemented, i.e. outer ring (5), and outer surface directly makes the sectional drawing of pulley.Among the figure: inner ring (1), dust cover (2), rolling element (3), retainer (4) all with NBS in shape, the physical dimension of all types of radial antifriction bearings part of the same name just the same, has interchangeability, it is outer ring (5), it is the utility model design elements, it is according to working condition, stressed size and designing.But its internal surface that contacts with rolling element (3) is the raceway face shape, and all types of radial antifriction bearing inner surfaces are raceway face in physical dimension and the NBS shape, physical dimension are identical.
Claims (3)
1, outer ring fluting radial antifriction bearing, it is by inner ring (1), dust cover (2), rolling element (3), retainer (4), fluting outer ring (5) is formed, wherein: inner ring (1), dust cover (2), rolling element (3), retainer (4) all with NBS in the shape of all types of radial antifriction bearings part of the same name, physical dimension is just the same, has interchangeability, it is characterized in that: the fluting outer ring (5) outer surface radially midline open width a, degree of depth t, the groove of radius r is as working surface, but its internal surface that contacts with rolling element (3) is the shape of raceway face, and the internal surface of all types of radial antifriction bearings outer ring is the shape of raceway face in physical dimension and the NBS, physical dimension is identical.
2, fluting radial antifriction bearing in outer ring according to claim 1 is characterized in that the flute profile of outer ring (5) can be split into U type, V-type or square.
3, fluting radial antifriction bearing in outer ring according to claim 1 is characterized in that: outer ring (5) outer surface is made pulley structure.
