Description
Technical field：
The utility model is related to mining machinery engineering device technique field, and in particular to a kind of novel hierarchical machine lower-shaft head bearing.
Background technology：
Spiral classifier is widely used in ore dressing plant, and operationally, classifier lower-shaft head bearing is immersed in ore pulp always
In, existing classifier lower-shaft head bearing is generally by the rolling bearing for being set in grader connecting shaft lower end and the bearing block being engaged
Composition, in spite of airtight and watertight padding sealing, but rolling bearing is easy to damage under the long-term submergence of ore pulp, and frequently changes rolling
Bearing can cause production to be interrupted, and cause deficiency in economic performance, and production cost is high.
Utility model content：
The purpose of this utility model is to provide a kind of novel hierarchical machine lower-shaft head bearing, solves current grader bottom axle
Hold the problem being easily easily damaged under the long-term submergence of ore pulp.
In order to solve the above-mentioned technical problem, the utility model provides a kind of novel hierarchical machine lower-shaft head bearing, and it includes
Hollow shaft flange disk, connecting shaft ring flange, the hollow shaft flange disk are set in the front end of quill shaft, the connecting shaft ring flange
The rear end coaxial welding of preceding card and connecting shaft, multiple bolts are through on the hollow shaft flange disk and the connecting shaft ring flange
Corresponding screw, the quill shaft is connected with the connecting shaft；It also includes axle sleeve and rubber bearing body, the axle sleeve set
It is located on the connecting shaft outer wall, the forward end seal of the axle sleeve and rear end seals with the preceding card of the connecting shaft ring flange and connects
Connect, from end face to being provided with a through hole, the connecting shaft relative other end on the rubber bearing body
It is plugged in the through hole of the rubber bearing body, and the preceding card of the connecting shaft ring flange and the rubber bearing sheet
The one side of body is abutted.
Alternatively, the rubber bearing body is square rubber pier.
Alternatively, the connecting shaft and the rubber bearing body interference grafting.
Advantage of the present utility model：The utility model is using rubber bearing body come the lower spindle nose branch as novel hierarchical machine
Hold, while support connection axle is played, the lower-shaft head bearing of quality of rubber materials is corrosion-resistant, be difficult to be damaged under the long-term submergence of ore pulp
It is bad, therefore avoid frequently changing lower-shaft head bearing so that grader operating efficiency is improved, production cost reduction.

Fig. 1 is structural representation of the present utility model；
Fig. 2 is the cooperation schematic diagram of quill shaft of the present utility model and hollow shaft flange；
Fig. 3 is connecting shaft of the present utility model and the cooperation schematic diagram for being connected shaft flange；
Fig. 4 is the structural representation of square rubber pier of the present utility model.
Brief description of the drawings is as follows：1st, hollow shaft flange disk；2nd, connecting shaft ring flange；3rd, axle sleeve；4th, rubber bearing body；401、
Through hole；5th, quill shaft；6th, connecting shaft；7th, bolt.
Specific embodiment：
To make the technical problems to be solved in the utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing
And specific embodiment is described in detail.
As Figure 1-4, in embodiment of the present utility model, there is provided a kind of novel hierarchical machine lower-shaft head bearing, its
Including hollow shaft flange disk 1, connecting shaft ring flange 2, axle sleeve 3 and rubber bearing body 4, hollow shaft flange disk 1 is set in hollow
The front end of axle 5, the rear end coaxial welding of card and connecting shaft 6 before connecting shaft ring flange 2, multiple bolts 7 pass through hollow shaft flange
Disk 1 and corresponding screw on connecting shaft ring flange 2, make quill shaft 5 be connected with connecting shaft 6；Axle sleeve 3 is set in the outer wall of connecting shaft 6
On, the forward end seal of axle sleeve 3 and rear end is tightly connected with the preceding card of connecting shaft ring flange 2, axle sleeve 3 is used to protect connecting shaft 6
From the long-term immersion of ore pulp, from end face to being provided with one relative other end on rubber bearing body 4
Through hole 401, connecting shaft 6 is plugged in the through hole 401 of rubber bearing body 4 with interference fit, and connecting shaft ring flange 2
Preceding card abutted with the one side of rubber bearing body 4, rubber bearing body 4 is adopted in specific embodiment of the utility model
Use square rubber pier；It should be noted that rubber bearing body 4 of the present utility model does not limit square rubber pier, circle can be used
The rubber pier of cylindrical rubber pier or other arbitrary shapes replaces.
The utility model, come the lower-shaft head bearing as novel hierarchical machine, is connected using rubber bearing body 4 supporting is played
While spindle 6, the lower-shaft head bearing of quality of rubber materials is corrosion-resistant, is difficult to be damaged under the long-term submergence of ore pulp, therefore avoid frequency
Numerous replacing lower-shaft head bearing so that grader operating efficiency is improved, production cost reduction.
Above is preferred embodiment of the present utility model, it is noted that for those skilled in the art
For, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improvements and modifications
Should be regarded as protection domain of the present utility model.
