Description
Technical field
The utility model relates to a kind of seal arrangement using in dedusting machinery, and especially a kind of useless powder is processed seal arrangement.
Background technique
In dedusting machinery, drive transmission shaft to turn round by speed reducer, the useless powder of oven dry is as stream-like, and mobility is splendid.For ensureing 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 purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of convenience, good bearing useless powder processing seal arrangement in working life that also can extend of sealing effect changed is provided.
The technological scheme providing according to the utility model, 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, be fixed with kidney-shaped pressing plate by adjusting bolt.
Described stuffing box packing is oil immersion asbestos packing.
Distance between described stuffing box packing and rolling bearing units is 60 ~ 70mm.
In the utility model, stuffing box packing is changed conveniently, has both ensured good sealing effect, has extended again the working life of bearing.

Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.
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, be fixed with kidney-shaped pressing plate 4 by adjusting bolt 8.
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 utility model 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, regulate the compaction degree of waist type pressing plate 4 by adjusting bolt 8, make 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 replacing, 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.
