Abstract
The invention relates to a waste powder processing and sealing device applicable to dust removing mechanical equipment. A plummer block is fixed on the left end face of a bearing support. A transmission shaft is rotationally mounted in the plummer block. A transmission shaft hole is formed in the bearing support. The transmission shaft penetrates the transmission shaft hole. A sealing filler hole is formed in the bearing support corresponding to the left end of the transmission shaft hole. The right end of the sealing filler hole is coaxially connected with the left end of the transmission shaft hole. The inner diameter of the sealing filler hole is larger than that of the transmission shaft hole. Sealing filler is disposed between the excircle of the transmission shaft and the inner wall of the sealing filler hole. A waist-shaped pressing plate is fixed on the bearing support at the left end of the sealing filler hole through an adjusting bolt. The waste powder processing and sealing device has the advantages that the sealing filler is convenient to replace, good sealing effect is guaranteed, and bearing service life is prolonged.
Description
Technical field
The present invention relates to a kind of seal arrangement using in dedusting machinery, especially a kind of useless powder is processed seal arrangement.
Background technique
In dedusting machinery, by speed reducer, drive transmission shaft to turn round, the useless powder of oven dry is as stream-like, and mobility is splendid.For guaranteeing the good and protection bearing of the environment of job site, must carry out good sealing to transmission axle head.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of convenience, good bearing useless powder processing seal arrangement in working life that also can extend of sealing effect changed is provided.
According to technological scheme provided by the invention, described useless powder is processed seal arrangement, comprise bearing spider, rolling bearing units and transmission shaft, on the left side of bearing spider, be fixed with rolling bearing units, in rolling bearing units, be rotatablely equipped with transmission shaft, on bearing spider, offer transmission axis hole, transmission shaft is through described transmission axis hole, in the bearing spider of corresponding transmission axis hole left end, offer stuffing box packing hole, the left part of the right part in stuffing box packing hole and transmission axis hole is coaxially and joins, the internal diameter in stuffing box packing hole is greater than the internal diameter of transmission axis hole, between the cylindrical of transmission shaft and the inwall in stuffing box packing hole, be provided with stuffing box packing, on the bearing spider of position, left part, stuffing box packing hole, by adjusting bolt, be fixed with kidney-shaped pressing plate.
Described stuffing box packing is oil immersion asbestos packing.
Distance between described stuffing box packing and rolling bearing units is 60 ~ 70mm.
In the present invention, stuffing box packing is changed conveniently, has both guaranteed good sealing effect, has extended again the working life of bearing.

Fig. 1 is plan view of the present invention.
Fig. 2 is plan view of the present invention.
Fig. 3 is the enlarged view of A part in Fig. 1.
Fig. 4 is the enlarged view of B part in Fig. 2.
Embodiment
Below in conjunction with specific embodiment, the invention will be further described.
This useless powder is processed seal arrangement, comprise bearing spider 3, rolling bearing units 2 and transmission shaft 1, on the left side of bearing spider 3, be fixed with rolling bearing units 2, in rolling bearing units 2, be rotatablely equipped with transmission shaft 1, on bearing spider 3, offer transmission axis hole 6, transmission shaft 1 is through described transmission axis hole 6, in the bearing spider 3 of corresponding transmission axis hole 6 left ends, offer stuffing box packing hole 7, the left part of the right part in stuffing box packing hole 7 and transmission axis hole 6 is coaxially and joins, the internal diameter in stuffing box packing hole 7 is greater than the internal diameter of transmission axis hole 6, between the cylindrical of transmission shaft 1 and the inwall in stuffing box packing hole 7, be provided with stuffing box packing 5, on the bearing spider 3 of 7 positions, left part, stuffing box packing hole, by adjusting bolt 8, be fixed with kidney-shaped pressing plate 4.
Described stuffing box packing 5 is oil immersion asbestos packing.
Distance between described stuffing box packing 5 and rolling bearing units 2 is 60 ~ 70mm.
The present invention is coiled in transmission shaft 1 by stuffing box packing 5 and encloses with the stuffing box packing hole 7 interior 2 ~ 3 of bearing spider 3, then waist type pressing plate 4 is injected to cavity and prop up asbestos packing 5, the compaction degree that regulates waist type pressing plate 4 by adjusting bolt 8, makes stuffing box packing 5 tensioning transmission shafts 1 play good seal action.Once after using long-time, stuffing box packing 5 was lost efficacy, because have the gap of 60 ~ 70mm to be also unlikely to damage rolling bearing units 2 apart from bearing, while changing, only adjusting bolt 8 need be unclamped simultaneously, push waist type pressing plate 4 open, new stuffing box packing 5 is wrapped in to transmission shaft 1 and encloses with the stuffing box packing hole 7 interior 2 ~ 3 of bearing spider 3.
Claims (3)
