The utility model discloses significantly reduced axle and the bearing fit phenomenon of skidding, first holder and the application of second holder can effectually prevent rotate eccentric to guarantee the operation of normally working of bearing and whole part, the utility model discloses simple structure, the design is compact, reasonable, has prolonged the life of bearing.
Description
Technical field
This utility model is related to a kind of bearing, especially a kind of rowing machine special bearing, belongs to field of exercise equipment.
Background technology
Mainly it is made up of outer ring, inner ring, rolling element, keeper, sealing ring, oils and fatss etc. for rowing machine bearing.Using
Between outer ring and inner ring, rolling element is installed, rolling element adopts ball-type, is evenly distributed between outer ring and inner ring, with a keeper
It is fixed up, sealing ring plays dust-proof and prevents oils and fatss leakage from acting on, oils and fatss play lubrication and form the effect such as oil film.Due to
Make when the movable pulley used in rowing machine is held using primitive axis and always skidding occurs, such using effect is not just very
Well it is impossible to reach good body-building effect.
Content of the invention
In order to solve the deficiencies in the prior art, this utility model provides a kind of rowing machine special bearing, increases
Frictional force, reduces axle and bearing fit skidding.
The technical scheme that this utility model is taken is as follows：A kind of rowing machine special bearing, including outer ring, inner ring, rolling element,
First retainer, the second retainer and dust cap, described rolling element connects outer ring and inner ring, and is protected with the first retainer and second
Hold frame positioning, make rolling element uniformly separately, described inner race width is much larger than outer ring width；Described outer ring is provided with dustproof groove, institute
State dust cap to be arranged in described dustproof groove.
Further, described interior collar dustproof groove is step groove.
Further, the external diameter of described outer ring is 22mm, and internal diameter is 18.02mm, and ditch curvature is 2.21mm, and width is 7mm.
Further, the external diameter of described inner ring is 11.82mm, and internal diameter is 8.08mm, and ditch curvature is 2.21mm, and width is
17.62mm.
Further, a diameter of 3.969mm of described rolling element.
Further, the external diameter of described first retainer and the second retainer is 16.6mm, and internal diameter is 13.1mm.
Further, the external diameter of described dust cap is 19.05mm, and internal diameter is 12.0mm.
Further, described rolling element is 7.
The beneficial effect that this utility model reaches is：
This utility model inner ring end face is longer, and when fitted shaft is installed, frictional force can become big, greatly reduces axle and bearing
Cooperation skidding；First retainer and the second retainer application effectively can prevent rotating eccentricity, thus ensure bearing and
Whole part normal work operates；This utility model structure is simple, compact to design, reasonable, extends the service life of bearing.
Brief description
Fig. 1 is structural representation of the present utility model；
In figure, 1, outer ring, 2, inner ring, 3, rolling element, the 4, first retainer, the 5, second retainer, 6, dust cap.
Specific embodiment
Below in conjunction with brief description and specific embodiment, this utility model is described in further detail：
As shown in figure 1, a kind of rowing machine special bearing, including outer ring 1, inner ring 2, rolling element 3, the first retainer 4, second
Retainer 5 and dust cap 6, described rolling element 4 connects outer ring 1 and inner ring 2, and is positioned with the first retainer 4 and the second retainer
5, make rolling element 3 uniformly separately it is ensured that inside and outside ring gap and axiality, described inner ring 2 width is much larger than outer ring 1 width；Described
Outer ring 1 is provided with dustproof groove, and described dust cap 6 is arranged in described dustproof groove, and injects oils and fatss in outer ring 1 with inner ring 2.
Further scheme is that described outer ring 1 dustproof groove is step groove.
Further scheme is that the external diameter of described outer ring 1 is 22mm, and internal diameter is 18.02mm, and ditch curvature is 2.21mm, wide
Spend for 7mm；The external diameter of described inner ring 2 is 11.82mm, and internal diameter is 8.08mm, and ditch curvature is 2.21mm, and width is 17.62mm；Institute
State a diameter of 3.969mm of rolling element 3；The external diameter of described first retainer 4 and the second retainer 5 is 16.6mm, and internal diameter is
13.1mm；The external diameter of described dust cap 6 is 19.05mm, and internal diameter is 12.0mm.
Further scheme is that described rolling element is 7.
In this utility model, described inner ring 2 width ratio outer ring 1 width two ends will be grown, and rubs when fitted shaft is installed
Power can become big, greatly reduces axle and bearing fit skidding；First retainer 4 and the second retainer 5 application can be effective
Prevent rotating eccentricity, thus ensure bearing and whole part normal work operating；This utility model structure is simple, and design is tight
Gather, rationally, extend the service life of bearing.
Particular embodiments described above, has carried out entering one to the purpose of this utility model, technical scheme and beneficial effect
Step describes in detail, be should be understood that and the foregoing is only specific embodiment of the utility model, is not limited to this
Utility model.This utility model expands to any new feature disclosing in this manual or any new combination, and discloses
Arbitrary new method or the step of process or any new combination.
