Description
Technical field
The utility model relates to a kind of dust-proof cover, and more particularly, it relates to a kind of ball cage dust-proof cover.
Background technique
Ball cage dust-proof cover is crucial parts in ball cage product, Main Function is to prevent that dust from entering in ball cage and preventing that the butter in ball cage from flowing out, comprise dust-proof cover main body, dust-proof cover main body comprises the paddy of crest and ripple, dust-proof cover main body is also provided with the axostylus axostyle opening for coordinating with axostylus axostyle and shrouds opening for shrouding with ball the ball coordinating, axostylus axostyle opening and ball shroud opening and mutually connect, wherein axostylus axostyle opening and axostylus axostyle are fixed and are sealed, ball shrouds opening and ball and shrouds and fix and seal, in transmission process, ball shrouds can follow axostylus axostyle, ball shrouds common rotation, when shrouding with axostylus axostyle, ball there is relative deflection, on crest between each point frequently near with away from, making ball shroud dust-proof cover continuously deforms, can reduce the working life that ball shrouds.
Model utility content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of ball cage dust-proof cover, shrouds opening the rolling bearing coordinating with axostylus axostyle ball cage is respectively set at axostylus axostyle opening and ball, makes that ball cage is no longer followed axostylus axostyle, ball shrouds rotation, and reduce distortion, thereby improve the life-span.
For achieving the above object, the utility model provides following technological scheme: a kind of ball cage dust-proof cover, comprise dust-proof cover main body, dust-proof cover main body comprises the paddy of crest and ripple, described dust-proof cover main body is also provided with the axostylus axostyle opening for coordinating with axostylus axostyle and shrouds opening for shrouding with ball the ball coordinating, described axostylus axostyle opening and ball shroud opening and mutually connect, described trough and axostylus axostyle, between shrouding, ball there is gap, described axostylus axostyle opening and ball shroud opening and are provided with rolling bearing, the inner ring of described rolling bearing respectively with axostylus axostyle outer circumferential face, ball shrouds outer circumferential face and closely connects, the end face of dust-proof cover is provided with annular dust cover dorsad, described dust-proof cover main body is also provided with fixed mechanism.
By adopting technique scheme, axostylus axostyle opening and ball shroud opening rolling bearing are set, the outer ring of rolling bearing and close contact sealing, and wherein axostylus axostyle opening, ball shroud between opening and bearing outer ring and can fasten by band, thereby reach sealing; Thereby on the inner peripheral surface of the inner ring of rolling bearing, can arrange seal ring realization and axostylus axostyle, ball shroud between realize sealing; And the rolling bearing dust cover on the end face of dust-proof cover main body dorsad both can prevent that dust from entering in rolling element, also can prevent that dust from entering in dust-proof cover, play the effect to the protection of ball cage; Because dust-proof cover main body connects by the realization of rolling bearing, and the frictional force of rolling bearing is minimum, therefore axostylus axostyle and ball shroud in the process of rotation, can't drive the rotation of dust-proof cover main body, even the frictional force that rolling bearing exists, after ball shrouds and deflects with axostylus axostyle, dust-proof cover main body can bend, now on rolling bearing, minimum frictional force will drive the rotation of dust-proof cover main body, need to overcome the elasticity of dust-proof cover main body, and make dust-proof cover subject distortion, therefore on rolling bearing, minimum frictional force cannot drive the rotation of dust-proof cover main body; If there is no deflection between axostylus axostyle and ball shroud, even if small frictional force can drive dust-proof cover rotation on rolling bearing, dust-proof cover can't deform, therefore axostylus axostyle opening and ball shroud opening and arrange after rolling bearing, dust-proof cover main body can not shrouded rotation because of axostylus axostyle, ball, and deformation occurs, thereby has improved working life, between trough and axostylus axostyle, there is gap, prevent that axostylus axostyle from driving the rotation of dust-proof cover main body.
The utility model is further set to: described fixed mechanism comprises and being arranged on dustproof looking in main body for fixing fixed hole.
Even by adopting above-mentioned scheme, by fixed hole is set, dust-proof cover main body just can realize by fixed hole and static object and further fixing, and prevents that dust-proof cover main body is rotated by external force.
The utility model is further set to: described fixing device comprises the eccentricity balance-weight block being arranged in dust-proof cover main body.
By adopting technique scheme, in the time that axostylus axostyle, ball shroud relative level face tilt, eccentric configuration block is set in dust-proof cover main body, now, the place that balancing weight is set can be positioned at below all the time, and dust-proof cover position is positioned, and prevents that dust-proof cover main body is rotated by external force.
The utility model is further set to: described bearing is provided with secondary dust cover towards the end face of dust-proof cover main body.
By adopting technique scheme, at two end faces of bearing, dust cover is set, dust-proof cover inner with the external world's two dust covers of being separated by, good dustproof effect.
