Abstract
The utility model provides a connection sealing structure between a transmission shaft and a housing in a friction type sand reclamation machine. The connection sealing structure is good in sealing and dust proofing performances, and normal usage of the reclamation machine is guaranteed. The connection sealing structure comprises a connecting seat and a bearing. The connecting seat is fixed on the housing of the reclamation machine, the bearing is mounted in a mounting hole of the connecting seat, two ends of the mounting hole are provided with an inner end cover and an outer end cover. The connection sealing structure is characterized in that between the transmission shaft and the inner end cover, the transmission shaft is in installation of interference with a dust proof sleeve, the radial circumference of the dust proof sleeve is provided with comb tooth shaped sealing structure, and graphite seal rings are embedded at the radial inner circumferences of the inner end cover and outer end cover; on the outer side of the inner end cover, a nut and a return stop gasket are mounted on the transmission shaft; on the outer side of the outer end cover, an elastic stopping ring is embedded at the inner circumference of the connecting seat.
Description
Technical field
The utility model relates to the recycling equipment of the old sand in Foundry Production, relates in particular to reclaiming machine for waste sand, is specially a kind of transmission shaft of the friction type reclaiming machine for waste sand and the connection sealing configuration of housing.
Background technique
The friction type reclaiming machine for waste sand is to rotate by transmission shaft band movable grinding disc, make mutually to rub, vibrate between old sand grain and old sand grain and between old sand grain and mill, the abrasive machining regeneration of realization to old sand grain, between general transmission shaft and the housing of regenerator, adopt bearing, bearing support to be connected, because old sand grain produces micronic dust in regenerative process, micronic dust enters in bearing, causes bearing lubrication insufficient even stuck, affects the normal work of regenerator.
Model utility content
For the problems referred to above, the utility model provides a kind of transmission shaft of the friction type reclaiming machine for waste sand and the connection sealing configuration of housing, and its good seal performance effectively realizes and preventing dust, and guarantees the normal use of regenerator.
Its technological scheme is such, the connection sealing configuration of a kind of transmission shaft of the friction type reclaiming machine for waste sand and housing, comprise connecting base and bearing, described connecting base is fixed on the housing of regenerator, described bearing is installed in the mounting hole of described connecting base, described mounting hole two ends are separately installed with inner end cap and outer end cap, it is characterized in that: between described transmission shaft and described inner end cap, on described transmission shaft, interference is provided with dirt-proof boot, the outer radial periphery of described dirt-proof boot is provided with the sealing configuration of comb teeth-shaped, the inside week of footpath of described inner end cap and described outer end cap is embedded with respectively carbon seal ring, be positioned at the outside of described inner end cap, nut and floor clip are installed on described transmission shaft, be positioned at the outside of described outer end cap, on the inner peripheral surface of described connecting base, be embedded with circlip.
It is further characterized in that:
Described bearing is provided with two groups, also comprise spacer ring one, spacer ring two and spacer ring three, described in two groups, between the outer ring of bearing, being provided with described spacer ring one, both sides is compressed by described inner end cap and described outer end cap respectively, described spacer ring one, is provided with described spacer ring two, both sides and by the step surface on described spacer ring three and described transmission shaft, is compressed respectively by spacing connection of bolt radially with described connecting base between the inner ring of bearing described in two groups.
Adopt after the utility model, between transmission shaft and inner end cap, on transmission shaft, interference is provided with dirt-proof boot, the outer radial periphery of dirt-proof boot is provided with the sealing configuration of comb teeth-shaped, the inside week of footpath of inner end cap and outer end cap is embedded with respectively carbon seal ring, its good seal performance, can effectively prevent that micronic dust from entering in bearing, be positioned at the outside of inner end cap, nut and floor clip are installed on transmission shaft, between the outer ring of two groups of bearings, be provided with spacer ring one, both sides are compressed by inner end cap and outer end cap respectively, spacer ring one is fixedly connected with by bolt radially with connecting base, between the inner ring of two groups of bearings, be provided with spacer ring two, both sides are compressed by the step surface on spacer ring three and transmission shaft respectively, can effectively prevent from becoming flexible because transmission shaft vibrates the dirt-proof boot causing, further guarantee its sealability, effectively prevent that micronic dust from entering in bearing, guarantee the normal use of regenerator.
