Abstract
The utility model relates to an inner ring of a tapered roller bearing. The inner ring comprises a tapered inner ring body, wherein a first annular retaining ring is arranged at the small opening end of the inner ring body and a second annular retaining ring is arranged at the big opening end of the inner ring body. The inner ring is characterized in that multiple oil inlets are formed in the first annular retaining ring. By adopting the technical scheme, the inner ring of the tapered roller bearing is provided and lubricating oil can conveniently enter the bearing through the first annular retaining ring, so that the lubricating effect of the bearing is good and the service life of the bearing is long.
Description
Technical field
The utility model relates to field of bearings, particularly a kind of inner ring of tapered roller bearing.
Background technique
At present, the inner ring of tapered roller bearing and rolling element large end face are sliding frictions, rolling friction need to be lubricated more fully relatively, the inner ring of existing tapered roller bearing generally comprises the inner ring body of taper, the osculum end of described inner ring body is provided with the first annular retaining ring, the big opening end of inner ring body is provided with the second annular retaining ring, the first annular retaining ring, the second annular retaining ring is used for preventing that tapered roller from departing from, the first annular retaining ring, the second annular retaining ring and inner ring body are wholely set, according to the pump of tapered roller bearing, inhale effect, lubricant oil flows to the larger end of diameter from rolling element diameter compared with small end, but, the inner ring of this structure, the first annular retaining ring can stop that lubricant oil enters in bearing, make the lubrication effect of bearing poor, life-span is short, and, when retainer is installed, need first its reaming to be shunk again, make its assembling have defect, install inconvenient.
Summary of the invention
The purpose of this utility model: in order to overcome the defect of prior art, the utility model provides a kind of inner ring of tapered roller bearing, and it can facilitate lubricant oil to enter in bearing from the first annular retaining ring, thereby makes the high lubricating effect of bearing, and the life-span is long.
The technical solution of the utility model: a kind of inner ring of tapered roller bearing, include the inner ring body of taper, the osculum end of described inner ring body is provided with the first annular retaining ring, the big opening end of inner ring body is provided with the second annular retaining ring, it is characterized in that: on the first described annular retaining ring, offer several filler openings.
Adopt technique scheme, by the filler opening arranging on the first annular retaining ring, can facilitate lubricant oil to enter in bearing from the first annular retaining ring, thereby make the high lubricating effect of bearing, the life-span is long.
Further setting of the present utility model: the first described annular retaining ring and the split of inner ring body arrange, and the first described annular shield ring sleeve is located at the osculum end of inner ring body.
Adopt above-mentioned further setting, can facilitate the installation of retainer, when retainer is installed, do not need its reaming to shrink again, make it easy for installation, and, the generation of assembling defect avoided.
Further setting more of the present utility model: the outboard end of the first described annular retaining ring is provided with oil groove, described oil groove and filler opening conducting.
Adopt above-mentioned further setting again, the oil groove of setting, can, so that conveniently store lubricant oil, guarantee that bearing has enough lubricant oil, thereby further extend its working life.
Further setting more of the present utility model: the first described annular retaining ring includes back-up ring body, described back-up ring body week is upwards provided with some ribs, between described adjacent rib, be provided with gap and form described filler opening, described rib is crooked setting laterally, forms described oil groove between rib and back-up ring body.
Adopt above-mentioned further setting again, the first annular retaining ring set-up mode of this structure, simple in structure, easy to process.
