Abstract
The utility model relates to a kind of universal joint bearing outer rings, particularly relates to a kind of new dustproof construction universal joint bearing outer rings.The utility model solves the technological scheme that its technical problem adopts: mode molding by extrusion forms a circular arc R-1 by between universal joint bearing outer rings stepped inner walls and interior bottom surface, circular arc R-1 radius is less than 1.5mm, circular arc R-2 is processed to form by mill between inwall and outer ring outer wall, circular arc R-2 radius is less than 0.8mm, is provided with anti-dust seal attachment face in external diameter direction, outer ring.The beneficial effects of the utility model are: the utility model structure is simple, and bearing capacity is strong, and stress distribution is reasonable, and are convenient to processing and assembling, and needle roller can reduce wearing and tearing when outer ring roll inside, thus improves the working life of cross-bearing.
Description
Technical field
The utility model relates to a kind of universal joint bearing outer rings, particularly relates to a kind of dustproof construction universal joint bearing outer rings.
Background technique
Existing Hooke's joint, its needle roller drops in the needle roller groove of inside, outer ring, and due to tool withdrawal groove, to process rear roughness poor, and bottom wall thickness is thinner than collar wall, and the invalid surface of contact of needle roller is comparatively large simultaneously, easily causes needle roller head stress to concentrate and causes needle roller cracked.Especially need to arrange needle roller groove on outer ring, outer ring is easily made to cause stress to concentrate, greatly affect the bulk strength of outer ring, for above problem, the way that usual employing increases outer ring bottom wall thickness solves, but not only adds the outer ring cost of raw material like this, also increases bearing integral weight, and be easily cause section components to wear and tear, cause universal joint early failue situation.
Model utility content
The utility model is inadequate in order to solve universal joint bearing outer rings bottom wall thickness, causes the problem that outer ring bulk strength is inadequate, provides a kind of dustproof universal joint bearing outer ring with new structure.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of new dustproof construction universal joint bearing outer rings, the stepped inner walls of outer ring is tangent with inner bottom surface and form circular arc R-1 and be connected, circular arc R-1 radius is less than 1.5mm, this fillet decreases outer ring bottom stress and concentrates, add effective thickness bottom outer ring, improve outer ring diapire intensity.Form circular arc R-2 between stepped inner walls with outer ring inwall to be connected, circular arc R-2 radius is less than 0.8mm.
As preferably, described circular arc is by cold-extrusion shaping, and cold-extrusion shaping improves the intensity of circular arc R-1, reduces cost of production.
As preferably, described circular arc R-2 is shaped by mill, reduces cost of production.
As preferably, external diameter direction, outer ring is provided with anti-dust seal attachment face, and become matrix arc surface to be connected between anti-dust seal attachment face with outer ring outer wall, its radius of arc becomes interference fit with oil seal lip radius R, effectively can prevent entering of dust and silt.
As preferably, be provided with one between outer ring outer wall and anti-dust seal attachment face and install guide surface, install guide surface and become inclined-plane to be connected with between outer ring outer wall, bevel angle a is 10 °-30 °, guide surface makes outer ring play positioning action when being pressed into transmission shaft fork entry, is convenient to outer ring assembling.
As preferably, outer bottom and the inner bottom surface of outer ring are provided with depressed area, conveniently store grease and prevent grinding burn.
Owing to adopting technique scheme, the beneficial effects of the utility model are: the utility model structure is simple, and bearing capacity is strong, stress distribution is reasonable, and be convenient to processing and assembling, needle roller can reduce wearing and tearing when outer ring roll inside, thus improves the working life of cross-bearing.
