Detailed description of the invention
Below in conjunction with the accompanying drawings, the present invention is described in further detail.
A kind of sealing automatically cleaning bearing, including outer ring 1, rolling member 2, inner ring 3, dust cap 4 and keeper 5；Described inner ring 3 and outer ring 1 are all arranged in circular and concentric, and rolling member 2 is located between inner ring 3 and outer ring 1；Described keeper 5 has two pieces, is divided into inner ring 3 both sides and touches with inner ring 3 phase；Described dust cap 4 is fixed on outer ring 1, and dust cap 4 extends internally, and dust cap 4 the inner is embedded at keeper 5, and dust cap 4 is arranged with keeper 5 gap；Described keeper 5 includes circular cone gear 5a and annulus gear 5b；Described circular cone gear 5a is the round table-like of hollow；Described annulus gear 5b is the circular of hollow；Described annulus gear 5b is integrally formed at cylinder gear 5a side；One keeper 5 is threadeded with another keeper 5 by bolt 6；Protruding and the outer wall laminating of both sides and keeper 5 in the middle part of the inwall of described inner ring 3.
The middle part of described outer ring 1 outer wall is provided with ring internal channel 1a, described internal channel 1a and outer ring 1 and is coaxially disposed；Outer wall both sides, described outer ring 1 are provided with interval and the side emissions groove 1b be arrangeding in parallel, and described internal channel 1a turns on side emissions groove 1b；Described internal channel 1a is 45 ° with the angle of cut of side emissions groove 1b.
This bearing arranges internal channel and side emissions groove at outer wall, improves the coefficient of friction of gear outer wall, it is to avoid skid, it is ensured that the stable operation of workpiece；Further, when scurrying into granulometric impurity between gear and belt, granulometric impurity is easily accumulated in internal channel, and under the band of belt draws, by arranging outside the emissions groove of side, plays self-cleaning effect.
Described annulus gear 5b outer wall offers caulking groove 5c；Described dust cap 4) the inner is provided with the first protruding 4a, the second protruding 4c of protruding 4b and the 3rd；Described second protruding 4b is positioned in the middle of the first protruding 4c of protruding 4a and the 3rd；There is the gap of 0.1 ~ 0.15mm in the described first protruding 4a and caulking groove 5c outer wall；There is the gap of 0.08 ~ 0.1mm in the described second protruding 4b and caulking groove 5c outer wall；There is the gap of 0.1 ~ 0.15mm in the described 3rd protruding 4c and caulking groove 5c outer wall.
The oils and fats that first protruding 4a is unnecessary in can storing bearing, hinders oils and fats excessive；Second protruding 4b plays sealing function；3rd protruding 4c prevents external dust from invading, and owing to forming longer labyrinth seal passage, makes the sealing effectiveness of bearing reach optimum degree.
Described keeper 5 is provided with connecting hole 5d, and described bolt 6 through corresponding connecting hole 5d and is fixed with nuts and washers.
