Abstract
The utility model relates to a sleeve extractor in the technical field of sleeve disassembling appliances on motors, which comprises a scooper comprising a pair of arc-shaped plates, an extracting cylinder, a rotating shaft protective plate, a hydraulic jack and a hydraulic work station, wherein the extracting cylinder is in threaded connection with the scooper; the rotating shaft protective plate is arranged in the extracting cylinder and on a rotating shaft; the hydraulic jack is connected with the extracting cylinder; and the hydraulic work station is connected with the hydraulic jack. The scooper comprising the pair of arc-shaped plates is connected with the extracting cylinder by a high-strength bolt; by matching the scooper with the hydraulic jack, the work pressure of the hydraulic work station is adjusted to a certain extent and can be maintained for a certain time; and in addition, the utility model not only can smoothly scoop the sleeve from the rotating shaft, but also can avoid the problem that a general scooper has insufficient strength which is not in the center and a magnet exciting coil is baked out by heating and the manufacturing or overhauling cost can be reduced.
Description
Technical field
The utility model relates to a kind of utensil of dismantling the motor upper bush, particularly a kind of sleeve extractor.
Background technology
Generally speaking, the sleeve of synchronous generator is to be assembled in the rotating shaft after heating, and its main effect is that the lubricant grease that prevents bearing chamber is scurried motor internal, the seal lubrication grease.In case motor breaks down, need the disintegration motor, necessary elder generation is pulling off sleeves in good condition, and epitrochanterian other accessory could disintegrate.Because the motor of general structure does not have easy impaired accessory, often all adopt induction heating or oxycetylene flame method that sleeve heating back is taken out.But for excitation lead structure is below arranged, because temperature is higher, be easy to line is damaged during heating, cause unnecessary loss and waste, it is far away apart from the distance of axle head to add upper bush, and common tool and method can't solve this type of special cold-drawn dismounting.
For example the sleeve of the major-minor engine 5GMG201E of HXN5 locomotive is assembled in the rotating shaft after heating, and its main effect is that the lubricant grease that prevents bearing chamber is scurried motor internal, the seal lubrication grease.Because the structure of motor is special, its four excitation leads are by the trough in the rotating shaft, below sleeve, the magnitude of interference of sleeve and rotating shaft has reached 0.117mm, the strength that claws approximately needs 60T, in case need the major-minor magnetic pole of disintegration motor, at first want pulling off sleeves, take out excitation lead, method commonly used is that take out the heating back, owing to be subjected to the restriction in space, induction heating fails to lay down, the uncontrollable again temperature of oxycetylene flame method, easily that excitation lead is roasting bad, existing technology and equipment also can't solve this type of problem.
The utility model content
The purpose of this utility model is, a kind of sleeve extractor is provided, and when motor breaks down and overhaul motor, just can successfully remove sleeve, and the assurance excitation wire is not suffered a loss, and reduces and makes or the cost of overhaul.
The technical solution adopted in the utility model is: a kind of sleeve extractor; it is characterized in that, comprise by a pair of arc constitute take off son, with take off son by be threaded extract tube, be arranged at extract tube inner and be installed on rotating shaft baffle in the rotating shaft, with extract tin a hydraulic jack that is connected and a hydraulic workstation that is connected with hydraulic jack.
Further, have screwed hole on the arcwall face of described arc, have tapped through hole on the plate face, an end medial surface of plate face has the groove structure that cooperates with the sleeve lateral surface.
Further, the screwed hole that has on the arcwall face of described arc evenly distributes.
The beneficial effects of the utility model are: taken off son and extract the high-intensity bolt of tube employing and be connected by what a pair of arc constituted, utilize it to cooperate with hydraulic jack, the operating pressure of regulating hydraulic workstation is to certain limit, the pressurize certain hour, can not only be successfully with sleeve cold clawing from the rotating shaft, and avoided adopting and general taken off sub-strength deficiency, strength, reduced the manufacturing or the cost of overhaul of sleeve not in the problem of center and the roasting bad excitation wire of heating.
Description of drawings
Fig. 1 is that the utility model uses structural representation.
Fig. 2 takes off the minor structure front view.
Fig. 3 is Fig. 2 cutaway view.
Reference numeral: the 1st, sleeve, the 2nd, take off son, 2-1 is an arcwall face, and 2-1a is a screwed hole, and 2-2 is the plate face, and 2-2a is a groove structure, 2-2b is a tapped through hole, the 3rd, extract tube, the 4th, rotating shaft baffle, the 5th, hydraulic jack.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1; a kind of sleeve extractor, comprise by a pair of arc constitute take off son 2, with take off son 2 by boltedly extract tube 3, be arranged at extract tube 3 inner and be installed on rotating shaft baffle 4 in the rotating shaft, with extract tin 3 hydraulic jack that are connected 5 and the hydraulic workstation that is connected with hydraulic jack 5.
As shown in Figures 2 and 3, have three equally distributed screwed hole 2-1a on the arcwall face 2-1 of arc, have a tapped through hole 2-2b on the plate face 2-2, the end medial surface of plate face 2-2 has the groove structure 2-2a that cooperates with the sleeve lateral surface.
During use, the son 2 of taking off that a pair of arc is constituted is enclosed within sleeve 1 outside, make and take off son 2 groove structure 2-2a and match, be screwed into trip bolt among the tapped through hole 2-2b on plate face 2-2 then, make and take off son inboard (inboard of a pair of arc) and sleeve closely cooperates with the outstanding position of sleeve 1.In the process of pulling off sleeves; for unlikely rotating shaft is subjected to damage; rotating shaft baffle 4 is installed in rotating shaft; rotating shaft baffle 4 is positioned at extracts tube 3; extract tube 3 one ends by bolt with take off sub the connection; the other end is connected with the hydraulic jack 5 of 100T by screw, and hydraulic jack 5 is connected with hydraulic workstation.The operating pressure of regulating hydraulic workstation is to certain limit, and the pressurize certain hour can not only be successfully goes out sleeve 1 cold-drawn from the rotating shaft, and avoided adopting the general problem that sub-strength deficiency, strength are not baked bad excitation lead in center and heating of taking off.
Claims (3)
1. sleeve extractor; it is characterized in that, comprise by a pair of arc constitute take off son (2), with take off son (2) by be threaded extract tube (3), be arranged at extract tube (3) inner and be installed on rotating shaft baffle (4) in the rotating shaft, with extract (3) hydraulic jack (5) that is connected and hydraulic workstation that is connected with hydraulic jack (5).
