Abstract
The invention discloses a seal structure of a shaft end of a mortar mixer. The seal structure of the shaft end of the mortar mixer comprises a main shaft and a double-tilt frame. Two seal devices are formed in shaft shoulders of the main shaft. The seal structure of the shaft end of the mortar mixer overcomes the disadvantage that a seal method of the shaft end of the existing mortar mixer utilizes joint action of felt and asbestos packing seal, once the seal loses efficacy, mortar is immersed into a bearing, heating of the bearing is conducted, and even a motor is burned. The improved seal structure of the shaft end of the mortar mixer changes the seal method into the two seal method of combing double-layer rubber seal and packing seal. The combined type seal improves service life of the bearing by more than two times.
Description
Technical field
The invention belongs to the construction mortar mixer, particularly a kind of sealing configuration of mortar mixer axle head.
Background technique
In prior art, mortar mixer immerses bearing in order to prevent mortar, it is designed to the structure that is comprised of seal felt, inner flange, agitating vessel, outward flange dish, upper cover, asbestos packing, end cap, bearing, watt stand, main shaft, what sealing configuration wherein adopted is felt and asbestos packing packing seal synergy, inside and outside flange plate is connected with agitating vessel, the sealing felt is used for filling up the gap of main shaft and agitating vessel, it is found that afterwards this structure, in case seal failure, mortar immerses bearing, cause bearing heating, even may motor damage.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of sealing configuration of mortar mixer axle head, can effectively solve sealing problem.
In order to solve the problems of the technologies described above, the invention provides following technological scheme: a kind of sealing configuration of mortar mixer axle head, comprise main shaft and two watt stand, the axle journal of described main shaft is connected with two watt stands by bearing, described main shaft arrives axle journal for the shaft shoulder from left to right, and turned right by the shaft shoulder inner flange, agitating vessel, outward flange dish are installed successively, also be fixed with respectively rubber plate between described agitating vessel and inside and outside flange plate, described outward flange dish the right is connecting stuffing seal, offers Leak hole on the two watt stands between described stuffing type sealing device and axle journal; Wherein, described stuffing type sealing device comprises by adjusting bolt and is fixed on the Gland on the outward flange dish and is filled in filler in the space that outward flange dish, main shaft, Gland three consist of.
Further, also be fixed with a upper cover on described outward flange dish.
It is pointed out that indication here from left to right, by the shaft shoulder just direction of an appointment of turning right, be in order conveniently to be described, be not to limit absolute orientation of the present invention.
The pressure available adjustment bolt of stuffing seal is regulated, utilize the excessive power consumpiton of pressure in stuffing seal large, the too small principle that leaks out mortar of pressure, machine is adjusted to made when only having a small amount of mortar to leak, sealing effect is best, the mortar of this moment also can be got rid of by Leak hole, and this sealing configuration is more than its bearing life improves twice.
Advantage: 1, the sealing load in stuffing box can be regulated by adjusting bolt.When 2, mortar leaks, can get rid of by Leak hole.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Fig. 1, the present invention is a kind of sealing configuration of mortar mixer axle head, comprise main shaft 1 and two watt stand 2, the axle journal of described main shaft 1 is connected with two watt stands 2 by bearing 11, described main shaft 1 arrives axle journal for the shaft shoulder from left to right, and turned right by the shaft shoulder inner flange 3, agitating vessel 5, outward flange dish 4 are installed successively, also be fixed with respectively rubber plate 6 between described agitating vessel 5 and inside and outside flange plate, described outward flange dish 4 the right are connecting stuffing seal, offer Leak hole 10 on the two watt stands 2 between described stuffing seal and axle journal; Wherein, described stuffing type sealing device comprises by adjusting bolt 9 and is fixed on the Gland 8 on outward flange dish 4 and is filled in filler 7 in the space that consists of between outward flange dish 4, the shaft shoulder, Gland 7 threes.
Further, also be fixed with a upper cover 12 on described outward flange dish 4.
It is pointed out that indication is the direction of an appointment from left to right here, is in order conveniently to be described, as limiting condition of the present invention.
The pressure available adjustment bolt 9 of stuffing seal is regulated, utilize the excessive power consumpiton of pressure in stuffing seal large, the too small principle that leaks out mortar of pressure, machine is adjusted to made when only having a small amount of mortar to leak, sealing effect is best, the mortar of this moment also can be got rid of by Leak hole, and this sealing configuration is more than its bearing life improves twice.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from structure of the present invention; can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
Claims (2)
1. the sealing configuration of a mortar mixer axle head, comprise main shaft and two watt stand, described main shaft arrives axle journal for the shaft shoulder from left to right, the axle journal of described main shaft is connected with two watt stands by bearing, main shaft is turned right by the shaft shoulder inner flange, agitating vessel, outward flange dish is installed successively, it is characterized in that: also be fixed with respectively rubber plate between described agitating vessel and inside and outside flange plate, described outward flange dish the right is connecting stuffing seal, offers Leak hole on the two watt stands between described stuffing seal and axle journal; Wherein, described stuffing seal comprises by adjusting bolt and is fixed on the Gland on the outward flange dish and is filled in filler in the space that outward flange dish, main shaft, Gland three consist of.
