Description

The bearing dismounting tool used in maintenance of fan process
Technical field
The utility model relates to axial flow blower maintenance auxiliary mould, particularly relates to the bearing dismounting tool used in a kind of maintenance of fan process.
Background technology
According to service technique condition, during train air-conditioning maintenance of fan, need former bearing removal, and change the new product bearing identical with original motor bearing designation.
During existing train air-conditioning maintenance of fan, move back and unload bearing and adopt hand to remove forcing press and dismantle, dismounting time tire is placed on workbench, the bearing dismantled is positioned at top side, the position of adjustment lower tire, rotor and upper tire, ensures that rotor axis is perpendicular to press bench face, and aligns pressure column center.Pull handle, even force, steady extrusion bearing, due to high temperature, high humidity environment, when carrying out train air-conditioning maintenance of fan, the generation corrosion had between bearing and armature spindle, because rotor is heavier, the handle action required dynamics that hand removes forcing press is comparatively large, and existing hand is removed forcing press and moved back bearing and need two people to coordinate, upper end one man operation, lower end one people cooperation buttresses rotor, prevent rotor tumble injury, after dismantling a side bearing, rotor is reversed end for end, dismounting opposite side bearing, two people's inconvenient operation, labour intensity is large, and efficiency is low.
Summary of the invention
Technical problem to be solved in the utility model is to provide the bearing dismounting tool used in a kind of maintenance of fan process, coordinate by using hydraulic cylinder and draw-in groove, rotor is placed in draw-in groove, armature spindle is placed in outside draw-in groove end plate with the bearing of hydraulic cylinder phase near-end, hydraulic cylinder immediate roof is used to push away armature spindle, armature spindle axially-movable, under the obstruction of draw-in groove end plate, bearing is taken off from armature spindle, flexible cover sheet is set bottom draw-in groove simultaneously, can prevent from causing damage to it in rotor axial moving process, hydraulic cylinder level is used to dismantle, a people is only needed to complete, reduce labour intensity, improve overhaul efficiency.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: the bearing dismounting tool used in a kind of maintenance of fan process, the draw-in groove comprising base plate and be located on plate top surface and hydraulic cylinder, described draw-in groove two end plates is provided with arc notch, the piston rod axis of described hydraulic cylinder and described arc notch dead in line.
Described hydraulic cylinder is fixedly mounted on plate top surface by means of supporting seat, baffle plate and front end panel, described supporting seat is cuboid block structure, its top is provided with the face of cylinder groove for holding hydraulic cylinder body, described front end panel is located between supporting seat and draw-in groove, described baffle plate is located at supporting seat rear, described baffle plate is provided with groove, the axis of described groove and the dead in line of arc notch.
Described draw-in groove inside bottom is provided with flexible cover sheet.
The beneficial effect adopting technique scheme to produce is: coordinate by using hydraulic cylinder and draw-in groove, rotor is placed in draw-in groove, armature spindle is placed in outside draw-in groove end plate with the bearing of hydraulic cylinder phase near-end, hydraulic cylinder immediate roof is used to push away armature spindle, armature spindle axially-movable, under the obstruction of draw-in groove end plate, bearing is taken off from armature spindle, flexible cover sheet is set bottom draw-in groove simultaneously, can prevent from causing damage to it in rotor axial moving process, hydraulic cylinder level is used to dismantle, after completing side bearing removal, directly rotor is turned around, and the bearing of other one end is stuck in outside draw-in groove end plate dismantles, a people is only needed to complete in whole process, reduce labour intensity, improve overhaul efficiency.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In the accompanying drawings: 1, draw-in groove; 2, front end panel; 3, base plate; 4, supporting seat; 5, baffle plate; 6, hydraulic cylinder; 7, piston rod.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The bearing of two ends of rotor is needed to change in maintenance of fan process, in Renewal process, need old bearing to remove, then new bearing is installed, but the method adopted at present is arranged on by rotor on vertical pressure machine to dismantle, one man operation forcing press, an other people is also had to buttress rotor body, prevent rotor tumble injury, labour costs is high, removal efficiency is low, for this reason, the utility model provides the bearing dismounting tool used in a kind of maintenance of fan process, comprise floor 3 and the draw-in groove 1 be located on the end face of floor 3 and hydraulic cylinder 6, described draw-in groove 1 two end plates is provided with arc notch, piston rod 7 axis of described hydraulic cylinder 6 and described arc notch dead in line, described hydraulic cylinder 6 is fixedly mounted on the end face of floor 3 by means of supporting seat 4, baffle plate 5 and front end panel 2, described supporting seat 4 is cuboid block structure, its top is provided with the face of cylinder groove for holding hydraulic cylinder 6 cylinder body, described front end panel 2 is located between supporting seat 4 and draw-in groove 1, described baffle plate 5 is located at supporting seat 4 rear, described baffle plate 5 is provided with groove, the axis of described groove and the dead in line of arc notch, described draw-in groove 1 inside bottom is provided with flexible cover sheet.
In concrete unloading process: coordinate by using hydraulic cylinder and draw-in groove, rotor is placed in draw-in groove, armature spindle is placed in outside draw-in groove end plate with the bearing of hydraulic cylinder phase near-end, hydraulic cylinder immediate roof is used to push away armature spindle, armature spindle axially-movable, under the obstruction of draw-in groove end plate, bearing is taken off from armature spindle, flexible cover sheet is set bottom draw-in groove simultaneously, can prevent from causing damage to it in rotor axial moving process, hydraulic cylinder level is used to dismantle, after completing side bearing removal, directly rotor is turned around, and the bearing of other one end is stuck in outside draw-in groove end plate dismantles, a people is only needed to complete in whole process, reduce labour intensity, improve overhaul efficiency.
