Description
Technical field
The utility model relates to a kind of powder concentrator, particularly a kind of powder concentrator transmission shaft step.
Background technique
Existing a kind of powder concentrator that is used for chemical industry powder, cement production process, it contains separating chamber, transmission shaft, axle sleeve, classification rotor and spreading disk.The upper end of axle sleeve is installed on the top of separating chamber, and the lower end of axle sleeve is positioned at the inside of separating chamber.The top of transmission shaft is installed on the upper bearing bracket, and this upper bearing bracket is arranged on the upper end of axle sleeve, and the bottom of transmission shaft is installed on the step, and this Lower shaft sleeve is arranged on the lower end of axle sleeve.Because powder concentrator when operation, the dust concentration in the separating chamber of powder concentrator is bigger, so dust gets into the inside of step easily, and this has not only accelerated the wearing and tearing of bearing, and has caused the leakage of bearing oil.
The model utility content
The technical problem that the utility model will solve provides a kind of powder concentrator transmission shaft step, and this transmission shaft step not only can prevent that dust from getting into that it is inner and cause the wearing and tearing of bearing, and can effectively solve the leakage problem of bearing oil.
For solving the problems of the technologies described above, a kind of powder concentrator transmission shaft of the utility model step contains bearing housing seat, cover flap, labyrinth bush and locking nut; The upper end of bearing housing seat is arranged on the lower end of powder concentrator axle sleeve, and the jacket wall of bearing housing seat is provided with bearing oil filling passage and compressed air channel, and labyrinth bush is the tube-in-tube structure of lower end band overlap; The overlap of labyrinth bush lower end is provided with lower concave ring; The lower end of cover flap is provided with lower convex ring, and the outside of cover flap lower end lower convex ring is provided with scrobicular ring, and the internal upper part of cover flap is provided with the oil sealing draw-in groove; The sidewall of cover flap be provided with bearing housing cover for seat wall on the vent that is connected of compressed air channel; Bearing is equipped with on the top of the inner chamber of bearing housing seat, and bearing is installed on the transmission shaft, and the cover flap passes through bolts assemblies on the bearing housing seat; Labyrinth bush is sleeved on the transmission shaft; The lower concave ring of labyrinth bush is positioned at the lower convex ring that cover flap lower end is provided with, and forms labyrinth channel between labyrinth bush and the cover flap, between the oil sealing draw-in groove that the outer surface of labyrinth bush and cover flap internal upper part are provided with oil sealing is housed; The upper end of labyrinth bush withstands on through packing ring on the inner ring of bearing, and the lower end of labyrinth bush withstands on the upper end of the locking nut lock that is sleeved on the transmission shaft.
Above-mentioned powder concentrator transmission shaft step owing to adopt labyrinth structure between bearing housing seat and the cover flap, therefore can significantly reduce the inside of dust entering bearing housing seat; Simultaneously since the sidewall of cover flap be provided with bearing housing cover for seat wall on the vent that is connected of compressed air channel; Therefore under compressed-air actuated effect; Not only there is air pressure in side space and stops the leakage of bearing oil under oil sealing, and has air pressure in the labyrinth channel between labyrinth bush and cover flap and intercept dust to get into the bearing housing seat inner.In sum, because said transmission shaft step adopts labyrinth structure and hermetic seal double seal, not only can prevent that therefore dust from getting into step inside and causing the wearing and tearing of bearing, and can effectively solve the leakage problem of bearing oil.
