Description
Technical field
The utility model belongs to universal joint technical field, more particularly to a kind of sealed universal joint of new outer oil seal.
Background technology
Universal joint is the important composition part in car transmissions, and the lubricating grease that need to be leaned in bearing during normal work plays profit
Slide the service life for acting on and ensureing product.But actual working environment is complicated, for prevent the intrusions such as silt, dust and contaminated oil
Fat in bearing oral area, it is necessary to set sealing ring.Current sealing structure is varied, and wherein outer oil seal is a major class.Such oil
Envelope is generally made up of main body and two lips, and the shoulder of main body and cross axle coordinates, two lips respectively with the outer wall of bearing with
Mouth plane coordinates, the sealed environment formed in bearing.The advantage of this sealing structure is that manufacture assembling is all fairly simple, still
Sealing effectiveness is not good.After universal joint works long hours, due to friction, oil sealing, which can generate heat, aging and to wear and tear, and sealing effectiveness is significantly
Reduction, so as to reduce the life-span of universal joint.
The content of the invention
The purpose of this utility model is to overcome the shortcomings of that prior art is present, and it is sealed to provide a kind of new outer oil seal
Universal joint, can prevent lubricating grease leakage in bearing, while can prevent outside muddy water, sand and dust etc. from invading inside universal joint bearing again,
Make bearing enclosure that there is lasting sealing property, so as to effectively improve the sealing effectiveness of universal joint, extend the use longevity of universal joint
Life.
The purpose of this utility model is completed by following technical solution, including cross axle, outer ring, needle roller, sealing
Circle, the spindle nose of the cross axle is set to one grade of shoulder, one grade of axle journal, passes through round-corner transition between shoulder and axle journal；The outer circle mouth
Portion's outer wall is provided with annular groove；The sealing ring is elastomer, provided with main body, outer lip and inner lip, in the main body of sealing ring
Side and the shoulder of cross axle are interference fitted；The annular groove of outer lip and outer ring oral area outer wall is interference fitted；Inner lip with it is outer
The internal circular surfaces of circle, the axle journal interference fit of cross axle.
Preferably, four spindle noses of described cross axle are set to one grade of shoulder, one grade of axle journal, axle journal passes through with shoulder
Round-corner transition.
Preferably, described outer ring is cup type, annular groove is being provided with the outer wall at oral area, channel section is in
Arc-shaped, internal circular surfaces are cylinder, and interior outer port part is provided with guide angle.
Preferably, the inner lip of described sealing ring is provided with two to three, respectively the first inner lip, the second epipharynx
The internal circular surfaces of mouth, the 3rd inner lip, the first inner lip and outer ring are interference fitted, the second inner lip, the 3rd inner lip and cross
The axle journal interference fit of axle.
The beneficial effects of the utility model are：By shafting oil seal outer lip sealed with outer ring oral area, inner lip respectively with outside
Inner circle and trunnion journal sealing are enclosed, main body is sealed with the formation of cross axle step, sealed layer by layer, is formed multiple tracks protective barrier, is prevented
Only the spilling of universal joint internal lubrication fat, while preventing the impurity such as muddy water, the sand and dust in the external world from entering inside universal joint bearing, deteriorates
Universal joint bearing internal lubrication, so as to extend the service life of universal joint.
