Abstract
The utility model relates to carrying rollers, specially labyrinth sealing carrying roller.Solve the problems, such as that existing supporting roller sealing effect is poor.Labyrinth sealing carrying roller includes roller, roll shaft and bearing；The sealing of roller both ends is fixed with the bearing cap being placed on roll shaft, bearing cap is equipped with the ring convex around roll shaft, sealing cover is fixed on roll shaft both ends outside roller, sealing cover seals against each other the annular groove of cooperation towards being provided on the end face of bearing cap with ring convex, cooperatively forms labyrinth seal structure by the sealing of ring convex and annular groove between bearing cap and sealing cover；Sealing ring is provided between ring convex and the cylinder contact surface of annular groove；The bearing is the bearing that both ends have diaphragm seal.The utility model forms three seals, is for first the labyrinth seal structure between bearing cap and sealing cover, second is sealing ring, and third road is the bearing i.e. double sealed bearing that both ends have diaphragm seal, has well solved bearing seal problem.
Description
Technical field
The utility model relates to carrying rollers, especially idler for belt conveyer, specially labyrinth sealing carrying roller.
Background technique
There was only one of reinforced seal inside existing idler for belt conveyer, it is inferior to run on coal mine for poor sealing effect
Under adverse circumstances, water, coal dust, coal slime etc., which are easily accessible in carrying roller, causes bearings at both ends to damage.
Summary of the invention
The utility model solves the problems, such as that existing supporting roller sealing effect is poor, provides a kind of labyrinth sealing carrying roller.
The utility model adopts the following technical scheme that realization: labyrinth sealing carrying roller, including roller, pass through roller in
The roll shaft of the heart, and in roller and interior snare be fixed on roll shaft, outer ring and roller inner wall cooperation bearing；The sealing of roller both ends
It is fixed with the bearing cap being placed on roll shaft, bearing cap is equipped with the ring convex around roll shaft towards the end face outside roller, is located at roller
It is fixed with sealing cover on outer roll shaft both ends, sealing cover seals against each other cooperation with ring convex towards being provided on the end face of bearing cap
Annular groove cooperatively forms labyrinth seal structure by the sealing of ring convex and annular groove between bearing cap and sealing cover；?
Sealing ring is provided between ring convex and the cylinder contact surface of annular groove.
Further, the bearing is the bearing that both ends have diaphragm seal；The both ends of plain bearing are unlimited, in
Ball or roller it is exposed, and both ends with diaphragm seal bearing by the diaphragm seal at both ends, bearing both ends are sealed, i.e.,
It can't see ball or roller, to further increase the sealing effect of bearing.
Labyrinth sealing carrying roller described in the utility model forms three seals, be for first bearing cap and sealing cover it
Between labyrinth seal structure, second is sealing ring, and third road is the bearing i.e. double sealed bearing that both ends have diaphragm seal, very
Solves the problems, such as bearing seal well, to improve the service life of carrying roller.Existing carrying roller can only use less than 1 month, this
Carrying roller described in utility model can be used 6 months or more, greatly extend carrying roller service life.Fan described in the utility model
Palace formula sealing idler roller can effectively extend belt conveyor service life, and processing is inexpensively simple, compact-sized, firm, exempts from daily dimension
Shield, can use in the case where inclement condition.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1- roller, 2- roll shaft, 3- bearing, 4- bearing cap, 5- ring convex, 6- sealing cover, 7- annular groove,
8- sealing ring.
Specific embodiment
Labyrinth sealing carrying roller, including roller 1, the roll shaft 2 across 1 center of roller, and positioned at roller 1, interior and interior snare is solid
In on roll shaft 2, outer ring and 1 inner wall of roller cooperation bearing 3；The sealing of 1 both ends of roller is fixed with the bearing cap 4 being placed on roll shaft 2,
Bearing cap 4 is equipped with the ring convex 5 around roll shaft 2 towards the end face outside roller 1, fixes on 2 both ends of roll shaft outside roller 1
There is a sealing cover 6, sealing cover 6 seals against each other the annular groove 7 of cooperation, bearing cap towards being provided on the end face of bearing cap 5 with ring convex 5
Labyrinth seal structure is cooperatively formed by the sealing of ring convex 5 and annular groove 7 between 4 and sealing cover 6；In ring convex 5 and annular
Sealing ring 8 is provided between the cylinder contact surface of groove 7；The bearing 3 is the bearing that both ends have diaphragm seal.Specific implementation
When, the sealing ring 8 is made of immersion oil wool felt, and sealing ring 8 made of immersion oil wool felt can preferably stop, cross drainage
Coal.The center line of the ring convex 5 is overlapped with the axis of roll shaft 2, so that more reasonable structure.When work, first of sealing is to pass through
Machining interference fit effectively prevents the water coal of bulky grain to pass through, and second sealing is filtered again by immersion oil wool felt
Water coal can be ignored by the water coal that three seals enter bearing.
