Specific embodiment
Below in conjunction with the accompanying drawings, this patent is described in further detail.
A kind of motor anti skid bearing, including bearing 100, locating shaft 200 and outer cover 300；The locating shaft 200 is arranged in
Bearing 100；The outer cover 300 includes cylindrical cover 301 and circular ring cover 302；The cylindrical cover 301 is in hollow cylindric, and circle
Column lid 301 is sheathed on outside bearing 100；The circular ring cover 302 is in hollow annular shape；The circular ring cover 302 is integrally formed at
301 one side of cylindrical cover, and circular ring cover 302 is arranged at intervals with locating shaft 200.
The locating shaft 200 includes 201 and second axis 202 of first axle of coaxial arrangement；The diameter of the first axle 201 is big
In the diameter of the second axis 202；Second axis 202 is arranged in bearing 100；The first axle 201 is integrally formed at the second axis 202
One side is simultaneously inconsistent with bearing 100；The first axle 201 is located at 100 one side of bearing, and it is another that circular ring cover 302 is located at bearing 100
Side.
The bearing 100 includes outer ring 104, ball 102, retainer 103 and inner ring 101；The inner ring 101 and outer ring
104 in circular and concentric setting, and ball 102 is located between inner ring 101 and outer ring 104；101 inner wall of inner ring
It is contacted with 202 phase of the second axis；104 outer wall of outer ring is contacted with 301 phase of cylindrical cover.
The ball 102 is embedded at retainer 103；The retainer 103 includes the retaining ring 103a being wholely set, keeps
The bar 103b and spacer ferrule 103c in annular shape.
The retaining ring 103a is in hollow ring-type；The equidistant axial arrangings of holding rod 103b are in retaining ring 103a mono-
Side, the gap of adjacent holding rod 103b are less than the diameter of ball 102；The holding rod 103b front and rear sides set fluted
103d；The radius of circular arc where the groove 103d is equal or slightly larger than 102 radius of ball.
The holding rod 103b inboard widths are less than outside width；The cross section of the holding rod 103b is in inverted isosceles
It is trapezoidal, the holding power of larger radial direction is provided for retainer 103.
The inner wall of the holding rod 103b free ends is provided with locating slot 103e；The spacer ferrule 103c is embedded at locating slot
103e；The spacer ferrule 103c internal diameters are not less than holding rod 103b internal diameters.The spacer ferrule 103c is wound by the iron plate of strip
Two enclose.On the one hand the setting of spacer ferrule 103c prevents ball 102 from unexpectedly jumping out, on the other hand, play opening holding rod
The effect of 103b provides holding power for the free end of holding rod 103b, meanwhile, it ensure that the hanging end group of all holding rod 103b
This is on same circumference.
The structure of retaining ring 103a is respectively provided with compared with holding rod 103b both ends, this retainer can save material and cost,
The weight of bearing is reduced, while is conducive to the assembling of ball 102 and retainer 103.
The setting of retainer 103, when ensure that bearing operation, the uniformity of raceway groove linear velocity reduces steel ball slip and rubs
The damage to working surface is wiped, substantially increases bearing life.
This bearing seal assembly passes through the setting of retainer so that ball remains relatively uniform distribution, improves load
The equilibrium of lotus, avoids stress concentration；Two row steel balls are kept in rational distance work, so as to substantially increase bearing reliability and
Service life.
The both sides of 300 outer wall of outer cover are provided with V-groove 303；The V-groove 303 of homonymy is equidistantly arranged, and V-groove
303 opening is outwardly.
This bearing sets V-groove in outer cover, improves the coefficient of friction of gear outer wall, avoids skidding, ensures the steady of workpiece
Fixed operation；Also, when scurrying into granulometric impurity between gear and belt, granulometric impurity is easily accumulated in V-groove, and in skin
Under the band of band draws, by being arranged outside V-groove, self-cleaning effect is played.The setting of V-groove so that no matter bearing rotates forward or anti-
Turn, it can be by the deficiency arranged, change unilateral fluting outer under the action of inertia of the impurity in V-groove.
The present invention is illustrated according to embodiment, on the premise of present principles are not departed from, if the present apparatus can also make
Dry modification and improvement.It should be pointed out that all technical solutions obtained using modes such as equivalent substitution or equivalent transformations, all fall within this
In the protection domain of invention.
