Abstract
The utility model discloses a mixing main shaft end labyrinth packing box of a concrete mixer, which includes a dust cover, a wear resistant ring, a flat flange fixed on a mixing cylinder and a shaft sleeve covered on the mixing main shaft; the dust cover is connected with the shaft sleeve by a fastener; the wear resistant ring is connected with the flat flange by another fastener; the dust cover is arranged in the wear resistant ring; spacing is left between the dust cover and the wear resistant ring. The mixing main shaft end labyrinth packing box of the concrete mixer has the advantages of simple structure, convenience in loading and unloading, low manufacturing cost, capability of wear mitigation and prolonged service life.
Description
Technical field
The utility model relates to concrete mixer, relates in particular to the stirring main-axis end labyrinth gland of concrete mixer.
Background technology
At present, before the floating seal of the stirring main-axis end of concrete mixer labyrinth gland is arranged one, this labyrinth gland is extremely important, and it is the first road seal protection that directly stops mud intrusion axle head.This axle head labyrinth gland is made up of wear ring and dust cap, dust cap is contained in and stirs on the main shaft, wear ring is contained in and stirs on the cylinder body, because stirring cylinder body is Welding Structure, easily produce distortion, make that the gap between wear ring and the dust cap is inhomogeneous, thereby cause wear ring and dust cap wearing and tearing to accelerate, cause initial failure.
The utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, be convenient to load and unload, low cost of manufacture, can slow down wearing and tearing, the stirring main-axis end labyrinth gland of the concrete mixer that increases the service life.
For solving the problems of the technologies described above, the utility model by the following technical solutions.
A kind of stirring main-axis end labyrinth gland of concrete mixer, comprise dust cap, wear ring, be fixedly arranged on and stir the face-flange on the cylinder body and be socketed on the axle sleeve that stirs on the main shaft, dust cap is connected on the axle sleeve by securing member, wear ring is connected on the face-flange by securing member, dust cap places in the wear ring, is provided with the gap between dust cap and the wear ring.
Described gap is 1~2 millimeter.
Compared with prior art, advantage of the present utility model just is: be provided with one through mach face-flange at the stirring cylinder body, the face-flange installed surface is smooth, the gap that has guaranteed dust cap and be installed between the wear ring on the face-flange is uniform, slow down the wearing and tearing between wear ring and the dust cap, prolonged the life-span of axle head labyrinth gland; This axle head labyrinth gland is simple in structure, be convenient to load and unload, low cost of manufacture, can improve the running stability that stirs main shaft.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Each label is represented among the figure:
1, stirs main shaft 2, flat key
3, dust cap 4, gap
5, wear ring 6, stirring cylinder body
7, face-flange 8, axle sleeve
The specific embodiment
As shown in Figure 1, the stirring main-axis end labyrinth gland of concrete mixer of the present utility model comprises dust cap 3, wear ring 5, face-flange 7 and axle sleeve 8, and face-flange 7 is welded in and stirs on the cylinder body 6, and axle sleeve 8 connects with stirring main shaft 1 by flat key 2.Dust cap 3 is connected on the axle sleeve 8 by bolt, and wear ring 5 is connected on the face-flange 7 by bolt, and dust cap 3 places in the wear ring 5, is provided with gap 4 between dust cap 3 and the wear ring 5, and gap 4 is 2 millimeters.Stir main shaft 1 during mixer work and drive axle sleeve 8 and dust cap 3 rotations, wear ring 5 keeps transfixion with face-flange 7.The gap of forming between dust cap 3 and the wear ring 54 forms labyrinth glands, requires gap 4 evenly and be 2 millimeters during work.The utility model is by being provided with one through mach, as to have smooth installed surface face-flange 7 at stirring cylinder body 6, again wear ring 5 is connected on the face-flange 7 by bolt, guaranteed that the gap 4 between wear ring 5 and the dust cap 3 is uniform, slow down the wearing and tearing between wear ring 5 and the dust cap 3, prolonged the life-span of axle head labyrinth gland; This axle head labyrinth gland is simple in structure, be convenient to load and unload, low cost of manufacture, can improve the running stability that stirs main shaft.
