Abstract
The utility model belongs to drum strainer prepares the field, especially relates to a novel drum strainer wheel hub. The problem of the shearing force of hub surface and main spoke side bolt is big is solved, this wheel hub includes: the axle sleeve for after connecting the pivot, drive wheel hub and rotate, a plurality of connecting pieces are connected around the axle sleeve, with make the whole protrusion of wheel hub be the cydariform between the axle sleeve behind the angulation, a plurality of bosss, with connecting piece quantity is unanimous, sets up on the connecting piece and be perpendicular with the connecting piece, main spoke, its length direction are gone up and are connected with the connecting piece, and the bottom board and the boss of main spoke are connected. The utility model discloses the structure makes drum strainer at work, the shearing force of bolt to the side of significantly reduce hub surface and the main spoke, and when the installation, the boss can play positioning accuracy's effect.
Description
Technical field
This utility model belongs to drum type filter screen preparation field, particularly relates to a kind of novel drum type filter screen wheel hub.
Background technology
Along with the development of domestic and international nuclear power projects, continuing to optimize of nuclear power station screening system equipment, various new techniques will capture rapidly this field.Drum type filter screen has become requisite equipment for filtering water in nuclear power station screening system, and drum type filter screen wheel hub is the base component of drum type filter screen skeleton, and wheel hub and king spoke support whole equipment.So the quality of wheel hub structure directly influences structural strength and the service life of whole equipment.
The wheel hub of current China drum type filter screen is arranged bolt with the connected mode of king spoke mainly by one and hub surface and king spoke side is fixed together, drum net is at work, drive motor drives whole equipment to rotate around the spindle by main beam and king spoke, rouse net under deadweight and sea water drag effect this moment, the shearing force that wheel hub bears with the connecting bolt of king spoke is very large, in addition Bolt to position precision is not high, it is easy to bolt looseness occur, runs jiggly phenomenon.
Utility model content
Technical problem to be solved in the utility model is in that to provide a kind of novel drum type filter screen wheel hub, solves the problem that hub surface is big with the shearing force of king spoke side bolt.
This utility model is achieved in that a kind of novel drum type filter screen wheel hub, and this wheel hub includes:
Axle sleeve, after connection rotating shaft, drives hub rotation；
Multiple connectors, are connected to the surrounding of described axle sleeve, and make wheel hub entirety protrude for cydariform between described axle sleeve after angulation；
Multiple boss, consistent with described connector quantity, it is arranged on connector and vertical with connector；
King spoke, its length direction is connected with connector, and the bottom end plate of king spoke is connected with boss.
Further, the length of boss is more than the 1/2 of king spoke cross-sectional width, less than king spoke cross-sectional width.
Further, multiple connectors is equivalently-sized.
Further, it is bolted between king spoke and connector and boss.
This utility model compared with prior art, has the beneficial effects that:
The boss structure that this utility model is arranged, make drum type filter screen at work, greatly reducing the shearing force of hub surface and king spoke side bolt, when mounted, boss can play the effect of positioning precision, due to when drum net operating, the weight of self and the resistance major part of sea water are born by the boss of wheel hub, and the shearing force suffered by the bolt of king spoke side is only small, it is possible to improve frame strength, improve the stability that equipment runs, extension device service life.
Accompanying drawing explanation
Fig. 1 is the wheel hub structure schematic diagram that this utility model embodiment provides.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain this utility model, be not used to limit this utility model.
Provide the structural representation of an embodiment referring to Fig. 1, wheel hub includes: axle sleeve 1, after connection rotating shaft, by driven by motor hub rotation；Axle sleeve 1 is provided with multiple connector 3, arrange radially between connector 3 and axle sleeve 1, spacing is identical, it is arranged on 360 ° of directions of axle sleeve surrounding, quantity is determined according to actual situation, connector 3 is connected to the end surrounding of axle sleeve, and makes wheel hub entirety protrude for cydariform between axle sleeve 1 after angulation；The effect of connector 3 is to connect king spoke 2, has certain angle between such king spoke 2 and axle sleeve 1, and the length of set connector 3 needs consistent, so ensures the uniformity in stress.For the huge pressure disperseing king spoke 2 to bear, in the position of the bottom end plate of king spoke 2, being vertically arranged boss 4 with connector 3, such king spoke 2 is when fixing, being connected by bolt M275 with connector 3 on its length direction, the bottom end plate of king spoke is connected by bolt M306 with boss 4.
Preferably simultaneously the length of boss 4 is set to the 3/4 of king spoke cross-sectional width.
In order to ensure to reduce the minimizing of shearing force suffered by the bolt that king spoke connects further, the angle of the setting between connector and axle sleeve is 80 degree.
Drum type filter screen is at work, greatly reduce the shearing force of hub surface and king spoke side bolt, when mounted, boss 4 can play the effect of positioning precision, owing to when drum net operating, the weight of self and the resistance major part of sea water are born by the boss 4 of wheel hub, the shearing force suffered by bolt of king spoke 2 side is only small, frame strength can be improved, improve the stability that equipment runs, extension device service life.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent replacement and improvement etc. made within spirit of the present utility model and principle, should be included within protection domain of the present utility model.
