Technical Field
The utility model relates to an overhaul of equipments technical field especially relates to an assembly and disassembly tools for large-scale water pump rubber bearing.
Background
The rubber bearing is used for supporting between the shaft and the pump shell and is mainly used for large-scale water pumps such as axial-flow pumps and deep-well pumps in power plants. The rubber bearing needs to be changed at the maintenance in-process to large-scale water pump, but the rubber bearing soaks in aqueous for a long time to constantly receive the pump shaft and rotate the contact, the vibration of production makes tiny rubbish particles such as silt get into rubber bearing and pump casing assembly department, and the jam when causing the rubber bearing to change is difficult to normally dismantle. Two semicircle orifices are reserved at the bearing end face to the pump casing, but its atress contact surface is less, and the casing diameter is great, consequently, uses general roof pressure instrument application of force dismouting process, and the clamp plate appears easily and receives the vibration to drop, is difficult to support the condition of casing for rubber bearing dismouting difficulty, the overhaul of the equipments is efficient, and is with high costs.
Disclosure of Invention
The utility model aims to solve the technical problem that a assembly and disassembly tools for large-scale water pump rubber bearing is provided, the defect of traditional water pump rubber bearing dismouting operation is overcome to this instrument, its simple structure, and dismouting operation convenient operation reduces intensity of labour and dismouting cost, has improved overhaul of equipments efficiency.
For solving the technical problem, the utility model discloses an assembly and disassembly tools for large-scale water pump rubber bearing includes first cross arm, second cross arm, long screw rod and nut, first cross arm includes steel sheet and arc boss, the arc boss is located the steel sheet surface is and coaxial arrangement, the length and the rubber bearing outer lane of steel sheet match, the arcwall face of arc boss matches with rubber bearing's inner circle, first cross arm center is opened there is the through-hole, second cross arm length is greater than the water pump shell external diameter and center is opened there is the through-hole, the long screw rod penetrates the through-hole of first cross arm and second cross arm, the nut twist in the long screw rod both ends.
Furthermore, the tool further comprises gaskets, wherein the gaskets are respectively sleeved at two ends of the long screw rod and are respectively positioned between the nut and the first cross arm and between the nut and the second cross arm.
Because the utility model discloses an assembly and disassembly tools for large-scale water pump rubber bearing has adopted above-mentioned technical scheme, and this instrument includes first cross arm, second cross arm, long screw rod and nut promptly, first cross arm includes steel sheet and arc boss, the arc boss is located the steel sheet surface is and coaxial arrangement, the length and the rubber bearing outer lane of steel sheet match, the arcwall face of arc boss matches with rubber bearing's inner circle, open at first cross arm center has the through-hole, second cross arm length is greater than the water pump shell external diameter and open at the center has the through-hole, long screw rod penetrates the through-hole of first cross arm and second cross arm, the nut twist in the long screw rod both ends. The tool overcomes the defects of the traditional water pump rubber bearing dismounting operation, has a simple structure, is convenient to operate in dismounting operation, reduces the labor intensity and the dismounting cost, and improves the equipment maintenance efficiency.
Drawings
The invention will be described in further detail with reference to the following drawings and embodiments:
FIG. 1 is a schematic structural view of a mounting and dismounting tool for a large-sized water pump rubber bearing of the present invention;
FIG. 2 is a schematic view of a first cross arm of the present tool;
FIG. 3 is a side view of FIG. 2;
FIG. 4 is a schematic view of a large water pump rubber bearing installed by the tool.
Detailed Description
Embodiment is as shown in fig. 1, fig. 2 and fig. 3, the utility model discloses an assembly and disassembly tools for large-scale water pump rubber bearing includes first cross arm 1, second cross arm 2, long screw rod 3 and nut 4, first cross arm 1 includes steel sheet 11 and arc boss 12, arc boss 12 is located steel sheet 11 surface and coaxial arrangement, the length and the rubber bearing 5 outer lane of steel sheet 11 match, the arcwall face of arc boss 12 matches with rubber bearing 5's inner circle, first cross arm 1 center is opened there is the through-hole, second cross arm 2 length is greater than water pump housing 6 external diameter and center and is opened there is the through-hole, long screw rod 3 penetrates first cross arm 1 and second cross arm 2's through-hole, nut 4 twist in long screw rod 3 both ends.
Preferably, the tool further comprises gaskets 7, and the gaskets 7 are respectively sleeved at two ends of the long screw rod 3 and are respectively positioned between the nut 4 and the first cross arm 1 and between the nut 4 and the second cross arm 2. The gasket is used for avoiding the direct friction with first cross arm and second cross arm when the nut is rotatory, improves the effort to first cross arm and second cross arm when the nut is rotatory, ensures the thrust of first cross arm to rubber bearing.
As shown in fig. 1, during the rubber bearing disassembling operation, the first cross arm 1 is placed on the end face of the mounting position of the rubber bearing 5, the steel plate 11 is positioned on the outer ring of the rubber bearing 5, the arc-shaped boss 12 extends into the inner ring of the rubber bearing 5, the second cross arm 2 is placed on the end face of the water pump housing 6 at the other end of the rubber bearing 5, the long screw 3 is adopted to penetrate through the central through holes of the first cross arm 1 and the second cross arm 2, the gasket 7 is respectively sleeved at the two ends of the long screw 3, the nut 4 is screwed to enable the first cross arm 1 to push the rubber bearing 5, the rubber bearing 5 moves towards the second cross arm 2 along the axial direction until the rubber bearing 5 is separated from the mounting position of the water pump housing 6.
As shown in fig. 4, during the rubber bearing mounting operation, the principle is the same as the rubber bearing dismounting operation, except that the arrangement positions of the first cross arm 1 and the second cross arm 2 are opposite, the second cross arm 2 is arranged on the end face of the rubber bearing 5 mounting position, the first cross arm 1 is abutted against the outer ring and the inner ring of the rubber bearing 5 from the inside of the water pump housing 6, the long screw 3 penetrates through the central through holes of the first cross arm 1 and the second cross arm 2, and the nut 4 is screwed to enable the first cross arm 1 to push the rubber bearing 5 to move to the mounting position along the axial direction, so that the rubber bearing mounting operation is completed.
The tool can ensure that the contact surface of the tool and the rubber bearing is fully stressed by effectively attaching the first cross arm to the end surfaces of the outer ring and the inner ring of the rubber bearing, and ensure the stress point pushed by the rubber bearing; the long screw rod reserves the axial movement allowance, and the sizing block can be additionally arranged according to the actual situation so as to meet the requirements of dismounting and mounting of different parts. The tool is simple in structure, easy to manufacture, convenient to disassemble and assemble, capable of reducing labor intensity of disassembling and assembling operation and capable of improving equipment maintenance operation efficiency.
