The utility model solves above-mentioned technical problem, provides a kind of axle supporting and sealing configuration of powder equipment.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of axle supporting of powder equipment and sealing configuration comprise reducing motor, place the reducer motor base of reducing motor, the rotating shaft be connected with reducing motor, be enclosed within the housing outside rotating shaft, two axle bearing seal structures, be enclosed within the front end of rotating shaft and tail end respectively and fix with housing, described axle bearing seal structure comprises heavily loaded tapered roller bearing and sealing configuration, the axle bearing seal structure of rotating shaft front end is located fixing by snap ring and spacer and reducer motor base, the axle bearing seal structure of rotating shaft tail end is fixed by tightening nut and spacer tensioning.
Further, the sealing configuration of described axle bearing seal structure comprises the bearing seal room sealing heavily loaded tapered roller bearing, first dust-proof rotary seal of bearing seal indoor and dust-proof rotary seal room, be enclosed within the friction axle sleeve in rotating shaft, lip vacuum seal is provided with between friction axle sleeve and bearing seal room, second dust-proof rotary seal of stuffing box bearing closed chamber and be enclosed within the outdoor cover of bearing seal that bearing seal outdoor and housing be connected and fixed, between the outdoor cover of described bearing seal and bearing seal room, between the outdoor cover of bearing seal and housing, seal ring seal is adopted between friction axle sleeve and rotating shaft.
Further, described friction axle sleeve adopts bearing inner race.
Further, described axle bearing seal structure is provided with Lou expects observation panel, and described leakage material observation panel runs through bearing closed chamber overcoat and bearing seal room.
Adopt the beneficial effect of the technical solution of the utility model:
1. two end axles supporting is for heavily loaded tapered roller bearing, and by the mode of tightening nut tensioning, avoids seriously sagging under the effect of conducting oneself with dignity of rotating shaft;
2. be provided with and Lou expect observation panel, and dust-proof rotary seal room and dust-proof rotary seal are set, avoid dust intrusion bearing and cause wearing and tearing;
3. use the bearing inner race of standard to rub axle sleeve as rotary dynamic seal, increase the service life, change easy to maintenance and cost is low.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 is structural representation in prior art;
Fig. 2 is the utility model structural representation;
Fig. 3 is the utility model axle bearing seal structure structural representation.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
The axle supporting of a kind of powder equipment shown in Fig. 2 and sealing configuration comprise reducing motor 10, place the reducer motor base of reducing motor 10, the rotating shaft 20 be connected with reducing motor 10, be enclosed within the housing 30 outside rotating shaft 20, two axle bearing seal structures 40, be enclosed within the front end of rotating shaft 20 and tail end respectively and fix with housing 30, described axle bearing seal structure 40 comprises heavily loaded tapered roller bearing 41 and sealing configuration, the axle bearing seal structure 40 of rotating shaft 20 front end is located fixing by snap ring 50 and spacer 60 with reducer motor base, the axle bearing seal structure 40 of rotating shaft 20 tail end is fixed by tightening nut 70 and spacer 60 tensioning.Two end axles supporting is heavily loaded tapered roller bearing 41, can bear larger axial load, and use tightening nut 70 to screw, and tension rotating shaft 20, greatly reduces the sagging of rotating shaft 20.
The bearing seal of axle shown in Fig. 3 structure 40 comprises heavily loaded tapered roller bearing 41, seal the bearing seal room 42 of heavily loaded tapered roller bearing 41, in bearing seal room 42 first dust-proof rotary seal 43 and dust-proof rotary seal room 44, be enclosed within the friction axle sleeve 45 in rotating shaft 20, lip vacuum seal 46 is provided with between friction axle sleeve 45 and bearing seal room 42, second dust-proof rotary seal 47 of stuffing box bearing closed chamber 42 and be enclosed within the outdoor cover 48 of the bearing seal be connected and fixed with housing 30 outside bearing seal room 42, between the outdoor cover 48 of described bearing seal and bearing seal room 42, between the outdoor cover 48 of bearing seal and housing 30, seal ring seal is adopted between friction axle sleeve 45 and rotating shaft 20.Friction axle sleeve 45 adopts the bearing inner race of standard, degree of finish and hardness high, wear resistance is strong, long service life, safeguard and change also economical convenient, friction axle sleeve 45 and seal ring combine, and avoid the second dust-proof rotary seal 47 and lip vacuum seal 46 and rotating shaft 20 direct friction.Bearing seal room 42 and the outdoor cover 48 of bearing seal have and Lou expects observation panel 49, whether wear and tear leak material in order to supervise the second dust-proof rotary seal 47 and lip vacuum seal 46, and the first dust-proof rotary seal 43 and dust-proof rotary seal room 44 are set, in case dust invades heavily loaded tapered roller bearing 41, cause the wearing and tearing of bearing.
Although specifically show in conjunction with preferred embodiment and describe the utility model; but those skilled in the art should be understood that; not departing from the spirit and scope of the present utility model that appended claims limits; in the form and details the utility model is made a variety of changes, be protection domain of the present utility model.
