Abstract
The utility model discloses a take bearing of shield, including inner circle and outer lane, the coaxial outer lane of arranging in of inner circle, the seal groove has been offered on the interior anchor ring of outer lane, just the cross -section of seal groove is the V -arrangement structure to be connected by an inclined plane that leans out the extension with the vertical face of outer lane the central axis looks vertically and constitute, be equipped with the shield between inner circle and the outer lane, the radial the inner and the outer periphery butt of inner circle of shield, the radial outer end correspondence of shield is equipped with and forms sealed complex turn -ups with the outer lane seal groove, the turn -ups constitute by a straight -edge section and the 2nd straight -edge section, a straight -edge section and seal groove on vertical face parallelly paste mutually, the inner of the 2nd straight -edge section is connected with a straight -edge section, the 2nd straight -edge section's outer end extend to with the seal groove on the inclined plane butt. Through adopting the structure mentioned above, the utility model provides a bearing is when pressfitting assembly shield, and the deformation that ability greatly reduced led to the fact the outer lane influences.
Description
Technical field
The utility model relates to a kind of bearing with dust cover.
Background technique
At present, existing most of bearing is provided with dust cover, the inner ring surface of meanwhile bearing outer ring correspondence can offer seal groove, the cross section of described seal groove is v-shaped structure, and connected and composed by the plane of inclination of a vertical plane perpendicular with outer ring central axis and an outward-dipping extension, and the radial inner end of described dust cover can abut with bearing inner race outer peripheral surface, the radial outer end of described dust cover then corresponding being provided with forms with outer ring seal groove the flange be sealed and matched, but as illustrated in fig. 1 and 2, the flange of existing dust cover connects and composes by the arcuate segment of a straight section and a solderless wrapped connection lopping, described straight section is parallel with the vertical plane on seal groove to be affixed, described arcuate segment is then abutted with the plane of inclination on seal groove by its outer arced surface.During due to assembling, people realize sealing by radial pressing by the seal groove of the flange of dust cover press-in outer ring, therefore the turnup structure of existing dust cover is adopted, in bonding processes, owing to being difficult to during arcuate segment pressurized deformation occurs, therefore can cause the plane of inclination on seal groove that deformation occurs, thus cause bearing outer ring entirety that deformation occurs, especially for the bearing of thin-walled series, above-mentioned this deformation will directly affect the overall assembly precision of bearing.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of bearing of novel band dust cover, and this bearing, when press fit arrangement dust cover, can reduce the influence of crust deformation caused outer ring greatly.
For achieving the above object, the utility model provides a kind of bearing with dust cover, include inner ring and outer ring, described inner ring is coaxially placed in outer ring, the inner ring surface of described outer ring offers seal groove, and the cross section of described seal groove is v-shaped structure, and connected and composed by the plane of inclination of a vertical plane perpendicular with outer ring central axis and an outward-dipping extension, dust cover is provided with between described inner ring and outer ring, the radial inner end of described dust cover abuts with inner ring outer peripheral surface, the radial outer end correspondence of described dust cover is provided with and forms with outer ring seal groove the flange be sealed and matched, described flange is made up of the first straight section and the second straight section, the first described straight section is parallel with the vertical plane on seal groove to be affixed, the inner of second straight section is connected with the first straight section, the outer end of the second straight section extends to and abuts with the plane of inclination on seal groove.
The beneficial effects of the utility model are: adopt said structure, because dust cover flange in the utility model is made up of the first straight section and the second straight section, the first described straight section is parallel with the vertical plane on seal groove to be affixed, the inner of second straight section is connected with the first straight section, the outer end of the second straight section extends to and abuts with the plane of inclination on seal groove, therefore when press fit arrangement dust cover, second straight section can first pressurized generation deformation, thus greatly reduce the risk of seal groove top incline pressurized generation deformation, and then also just effectively reduce the probability that deformation occurs bearing outer ring entirety.
It is parallel with dust cover that the utility model can be set to the first described straight section further, and connected by a transition linkage section.
Accompanying drawing explanation
Fig. 1 is the structural drawing of prior art;
Fig. 2 is the A portion enlarged view of Fig. 1;
Fig. 3 is structural drawing of the present utility model;
Fig. 4 is the B portion enlarged view of Fig. 3.
Embodiment
As Fig. 3, a kind of bearing with dust cover is given shown in 4, include inner ring 1 and outer ring 2, described inner ring 1 is coaxially placed in outer ring 2, the inner ring surface of described outer ring 2 offers seal groove 3, and the cross section of described seal groove 3 is v-shaped structure, and connected and composed by the plane of inclination 32 of a vertical plane 31 perpendicular with outer ring 2 central axis and an outward-dipping extension, dust cover 4 is provided with between described inner ring 1 and outer ring 2, the radial inner end of described dust cover 4 abuts with inner ring 1 outer peripheral surface, the radial outer end correspondence of described dust cover 4 is provided with and forms with outer ring seal groove 3 flange 5 be sealed and matched, described flange 5 is made up of the first straight section 51 and the second straight section 52, the first described straight section 51 is parallel with the vertical plane 31 on seal groove 3 to be affixed, the inner of second straight section 52 is connected with the first straight section 51, the outer end of the second straight section 52 extends to and abuts with the plane of inclination 32 on seal groove 3.The first described straight section 51 is parallel with dust cover 4, and is connected by a transition linkage section 6.
Adopt said structure, because dust cover flange 5 in the utility model is made up of the first straight section 51 and the second straight section 52, the first described straight section 51 is parallel with the vertical plane 31 on seal groove 3 to be affixed, the inner of second straight section 52 is connected with the first straight section 51, the outer end of the second straight section 52 extends to and abuts with the plane of inclination 32 on seal groove 3, therefore when press fit arrangement dust cover 4, second straight section 52 meeting first pressurized generation deformation, thus greatly reduce the risk of seal groove 3 top incline 32 pressurized generation deformation, and then also just effectively reduce the probability that deformation occurs bearing outer ring 2 entirety.
