Totally enclosed type roller bearing component
Technical field
It the utility model is related to field of bearings, and in particular to a kind of totally enclosed type roller bearing component.
Background technology
The combined roller contact bearing component used currently on the market, in use, Bearing inner are filled with lubricant grease,
For filling gap and anti-rust action, ensure the operation of bearing steady and smooth, but unavoidably there is oil during bearing operation
Fat is revealed, and easily causes bearing wear, so that the damage of bearing is caused, and the grease revealed can pollute use environment.
The content of the invention
To solve the above problems, the utility model proposes a kind of totally enclosed type roller bearing component, design is reasonable, structure letter
It is single so that lubricant grease, to sealing, notifies to be fully sealed in component not only in Bearing inner.
A kind of totally enclosed type roller bearing component, it includes axis, stent and bearing;The bracket cross section is concave;Institute
State axis and run through stent two side, be interference fitted between stent, and bearing is set with axis, between stent two side;
The bearing includes outer ring, inner ring and baffle ring, and inner ring is sleeved on axis, and outer ring is sleeved on inner ring, passes through roller and inner ring
Connection is rolled, and outer ring is stretched out outside stent, and the clearance fit between frame bottom, baffle ring are installed on axial the two of inside and outside circle
Between the corresponding end at end, the clearance fit between axis, baffle ring end face with and roller contact, other end be provided with ring-type platform
Rank, is provided with fluid sealant on step, and slight interference contacts between fluid sealant and outer ring, has a relative rotational motion capability, outside fluid sealant
End face is stretched out outside outer ring, the tight Interference contact between stent, with stent without relatively kinetic force.
The radial internal clearance of the twice bearing in gap between the baffle ring and axis.
The fluid sealant is rubber material, using reinforcing nitrile rubber.
The stent madial wall makees coarse processing.
The utility model advantage is that design is reasonable, simple in structure, and fluid sealant is set on end ring, utilizes fluid sealant
The Interference contact between stent and bearing outer ring so that lubricant grease, to sealing, is notified in component not only in Bearing inner
Inside it is fully sealed.

Specific embodiment
Referring to the drawings 1-2, a kind of totally enclosed type roller bearing component, it includes axis 02, stent 01 and bearing 07;It is described
01 section of stent is concave;The axis 02 runs through 01 two side of stent, is interference fitted between stent 01, and be set with axis 02
There is bearing 07, between 01 two side of stent;The bearing 07 includes outer ring 03, inner ring 04 and baffle ring 05,04 set of inner ring
On axis 02, outer ring 03 is sleeved on inner ring 04, is rolled and connected by roller and inner ring 04, and stent 01 is stretched out in outer ring 03
Outside, the clearance fit and between 01 bottom of stent, baffle ring 05 be installed on inner ring 04, outer ring 03 axial both ends corresponding end it
Between, the clearance fit between axis 02,05 end face of baffle ring with and roller contact, other end be provided with circular step, on step
Fluid sealant 06 is provided with, slight interference contacts between fluid sealant 06 and outer ring 03, has relative rotational motion capability, 06 outer end of fluid sealant
Face is stretched out outside outer ring 03, the tight Interference contact between stent 01, with stent 01 without relatively kinetic force.
The radial internal clearance of the twice bearing 07 in gap between the baffle ring 05 and axis 02.
The fluid sealant 06 is rubber material, using reinforcing nitrile rubber.
01 madial wall of stent makees coarse processing.
The utility model advantage is that design is reasonable, simple in structure, and fluid sealant is set on end ring, utilizes fluid sealant
The Interference contact between stent and bearing outer ring so that lubricant grease, to sealing, is notified in component not only in Bearing inner
Inside it is fully sealed.
