It is sliding, improve the service life of bearing.
To achieve the above object, the utility model provides the spacer ring in a kind of bearing of connecting, which is used for being arranged on
Between clutch shaft bearing and second bearing, the inner ring axial series of clutch shaft bearing and second bearing are in interior axle, the inner hole wall of spacer ring
For being sleeved in interior axle, the side of the inner hole wall of spacer ring is recessed oil storage tank, and the ring wall of spacer ring is equipped with nozzle opening, nozzle opening
Oil storage tank is connected, oil duct, the axial wall and alignment oil storage tank of oil duct perforation interior axle are equipped with interior axle.
Preferably, the outer ring of clutch shaft bearing and second bearing is axially inlaid in the endoporus of part, in the hole wall of endoporus
Meta has installed baffle ring, and baffle ring is between clutch shaft bearing and the outer ring of second bearing.
Preferably, spacer ring and baffle ring surround gap on the inside of clutch shaft bearing and second bearing, and nozzle opening sprays lubricating oil
Enter and come to carry out cooling and lubricating to the rolling element of clutch shaft bearing and second bearing in gap.
Compared with prior art, the utility model has the advantages that：The spacer ring establishes interior oil using stepped hole
Chamber, realizes oil storage function, the radial direction oil connection of internal oil pocket and interior axle, and the axial assembling of spacer ring and its interior axle need not be determined
Position, optional position assembling can realize that oil duct is connected with oil pocket, and the machine oil of interior oil intracavitary is realized by the setting of nozzle opening
The nozzle function of oil pocket inside spacer ring, it is possible to achieve give rolling bearing forced feed lubrication, improve the service life of bearing.
