Description
Technical field
Field of bearings is the utility model is related to, more particularly to a kind of Jing Yin ceiling fan special bearing.
Background technology
The characteristics of special bearing of Jing Yin ceiling fan, seeks to avoid to produce noise when work, present Jing Yin ceiling fan
Special bearing be ball using a diameter of 5.953mm mostly, the clearance of this ball be CO, and the later rework rate of installation compares
Height, and can produce noise after working long hours.
The sealing of the dust cap of the special bearing of present Jing Yin ceiling fan is not so good, easily causes after working long hours
The leakage of lubricating grease and the entrance of external dust, cause to produce noise when bearing working.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of Jing Yin ceiling fan special bearing, increases the straight of ball
Footpath, load is increased, have adjusted inner ring ditch coefficient of curvature and outer ring coefficient of curvature, add making up for ball and raceway face
Degree, reduces end-play, adds auxiliary seal ring, improve sealing.
Technical scheme is used by the utility model solves its technical problem：A kind of Jing Yin ceiling fan special bearing is provided,
Including outer ring and inner ring, several balls are evenly equipped between described outer ring and inner ring, are mounted on the outside of described ball
The retainer being connected, both sides are symmetrically installed with dust cap between described outer ring and inner ring, and the section of the dust cap is in S
Shape, the upper end curved portions of the dust cap are embedded into the groove on the inside of outer ring, and are disposed with the outside of the curved portions of upper end along outer ring
The outsourcing portion radially extended, the lower end of described dust cap are disposed with inside bending part, are nested and fixed at the bending part auxiliary
Sealing ring is helped, the auxiliary seal ring is embedded into the groove on the outside of inner ring and leaves an intersegmental gap, described rolling with bottom portion of groove
A diameter of 6.35mm of pearl, described inner ring ditch coefficient of curvature are 0.5086, and the ditch coefficient of curvature of outer ring is 0.5134.
Preferably, the end-play of described Jing Yin ceiling fan special bearing is 8-13um.
It is further preferred, rivet is installed on the retainer between adjacent ball and connects left and right two parts of retainer
It is connected together.
Beneficial effect：A kind of Jing Yin ceiling fan special bearing is the utility model is related to, the diameter of ball is increased, increases negative
Lotus, inner ring ditch coefficient of curvature and outer ring coefficient of curvature are have adjusted, adds ball and the degree of making up of raceway face, reduces axial direction
Clearance, auxiliary seal ring is added, improve sealing, prevent bearing from noise occur, improve the service life of bearing.

Embodiment
With reference to specific embodiment, the utility model is expanded on further.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it is to be understood that reading the content of the utility model instruction
Afterwards, those skilled in the art can make various changes or modifications to the utility model, and these equivalent form of values equally fall within this Shen
Please appended claims limited range.
As shown in Figure 1-2, embodiment of the present utility model is related to a kind of Jing Yin ceiling fan special bearing, including the He of outer ring 1
Inner ring 2, is evenly equipped with several balls 3 between described outer ring 1 and inner ring 2, the outside of described ball 3 is mounted on being linked to be one
The retainer 6 of body, both sides are symmetrically installed with dust cap 4 between described outer ring 1 and inner ring 2, and the section of the dust cap 4 is S-shaped,
The upper end curved portions 8 of the dust cap 4 are embedded into the groove of the inner side of outer ring 1, and the outside of upper end curved portions 8 is disposed with along outer ring
The 1 outsourcing portion 7 radially extended, the lower end of described dust cap 4 are disposed with inside bending part 9, are fixed by socket at the bending part 9
There is auxiliary seal ring 10, the auxiliary seal ring 10 is embedded into the groove in the outside of inner ring 2 and leaves an intersegmental gap with bottom portion of groove,
A diameter of 6.35mm of described ball 3, the described ditch coefficient of curvature of inner ring 2 are 0.5086, and the ditch coefficient of curvature of outer ring 1 is
0.5134。
The end-play of described Jing Yin ceiling fan special bearing is 8-13um, prevents ball 3 from moving.
It is further preferred, rivet 5 is installed by the left and right two of retainer 6 on the retainer 6 between adjacent ball 3
Divide and link together, installation is firm.
