Abstract
The present invention relates to a kind of rowing machine special bearing, including outer ring, inner ring, rolling element, the first retainer, the second retainer, dust cap and connecting mandrel, described rolling element connects outer ring and inner ring, and position with the first retainer and the second retainer, rolling element is made uniformly to separate, described inner ring is installed fixing by connecting mandrel, and described inner race width is much larger than outer ring width；Described outer ring is provided with dustproof groove, and described dust cap is arranged in described dustproof groove.Present invention substantially reduces axle and bearing fit skidding, the first retainer and the application of the second retainer and can effectively prevent rotating eccentricity, thus ensure that bearing and whole parts normally work operating；Present configuration is simple, compact to design, reasonable, extends the service life of bearing.
Description
Technical field
The present invention relates to a kind of bearing, especially a kind of rowing machine special bearing, belong to field of exercise equipment.
Background technology
Mainly it is made up of outer ring, inner ring, rolling element, keeper, sealing ring, oils and fats etc. for rowing machine bearing.Use
Installing rolling element between outer ring and inner ring, rolling element uses ball-type, is evenly distributed between outer ring and inner ring, with a keeper
Being fixed up, sealing ring plays dust-proof and prevents the oils and fats effect of leaking outside, and oils and fats plays lubrication and forms the effects such as oil film.Due to
Making the movable pulley used in rowing machine uses primitive axis always to there will be skidding when holding, and such using effect is not the most very
Good, it is impossible to reach good body-building effect.
Summary of the invention
In order to solve the deficiencies in the prior art, the invention provides a kind of rowing machine special bearing, increase friction
Power, reduces axle and bearing fit skidding.
The technical scheme that the present invention takes 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 with the first retainer and the second retainer
Location, makes rolling element uniformly separate, and described inner race width is much larger than outer ring width；Described outer ring is provided with dustproof groove, described anti-
Dirt lid is 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, 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 present invention reaches to provide the benefit that:
Inner ring end face of the present invention is longer, and when fitted shaft is installed, frictional force can become big, greatly reduces axle and skids with bearing fit
Phenomenon；First retainer and the application of the second retainer can effectively prevent rotating eccentricity, thus ensure bearing and whole parts
Normally work operating；Present configuration is simple, compact to design, reasonable, extends the service life of bearing.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
In figure, 1, outer ring, 2, inner ring, 3, rolling element, the 4, first retainer, the 5, second retainer, 6, dust cap.
Detailed description of the invention
Illustrate that the present invention is described in further detail with detailed description of the invention below in conjunction with accompanying drawing:
As it is shown in figure 1, a kind of rowing machine special bearing, keep including outer ring 1, inner ring 2, rolling element the 3, first retainer 4, second
Frame 5 and dust cap 6, described rolling element 4 connects outer ring 1 and inner ring 2, and positions 5 with the first retainer 4 and the second retainer, makes
Rolling element 3 uniformly separates, it is ensured that Internal and external cycle gap and axiality, and described inner ring 2 width is much larger than outer ring 1 width；Described outer ring 1
Being provided with dustproof groove, described dust cap 6 is arranged in described dustproof groove, and injects oils and fats 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
Degree is 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 the present invention, width two ends, described inner ring 2 width ratio outer ring 1 will be grown, the frictional force meeting when fitted shaft is installed
Become big, greatly reduce axle and bearing fit skidding；First retainer 4 and the application of the second retainer 5 can effectively be prevented
Only rotating eccentricity, thus ensure that bearing and whole parts normally work operating；Present configuration is simple, compact to design, reasonable, prolongs
Grow the service life of bearing.
Particular embodiments described above, has been carried out the purpose of the present invention, technical scheme and beneficial effect the most in detail
Describe in detail bright, be it should be understood that the specific embodiment that the foregoing is only the present invention, be not limited to the present invention.This
Invention expands to any new feature disclosed in this manual or any new combination, and the arbitrary new method that discloses or
The step of process or any new combination.
