Abstract
The utility model provides an external wheel dismounting device, which is specifically used for dismounting external wheels such as bearings, gears, chain wheels, belt pulleys (comprising double belt pulley), fan impellers, etc. The dismounting device is characterized in that the bottom of a screw rod is provided with a conical body which is sheathed on the screw rod; a pressure bearing is arranged in the conical body; a radial screw hole is arranged in a nut which is connected with the screw rod; the screw rod is symmetrically connected with two or three working claws through the radial screw holes; the working claw is composed of a connecting rod and a hanging hook which is fixed on the connecting rod and is capable of being dismounted. Because the utility model is provided with the conical body provided with the built-in pressure bearing and the improved hanging hook, the utility model is capable of effectively avoiding displacement of a central fulcrum, thoroughly solves the problems that shafts are easily bent, dismounted wheels are easily damaged and a part of the external wheels is not dismounted, simultaneously reduces friction effectively, relatively enhances serviceability rate of wheel shaft making holes and spare caps of the screw rod, shortens time of replacing the wheel and obviously enhances work efficiency. The utility model has the advantages of simple structure, convenient use, flexible operation, timely maintenance, strong applicability, convenient generalization, etc.
Description
Technical field: the utility model relates to a kind of provision for disengagement, particularly relates to a kind of provision for disengagement that described external application wheels such as bearing, gear, sprocket wheel, belt pulley (comprising two belt pulleys), draught fan impeller are dismantled that is specifically designed to.
Background technology: when equipment is carried out flight-line maintenance, often will be with the dismounting of external application wheel.Dismounting for the external application wheel for a long time never has specific purpose tool, but the external application wheel together is fixed on the workbench together with connecting axle, firmly knock with iron hammer then, so not only waste time and energy, and often cause connecting axle bending and external application to take turns impaired distortion, thereby cause and to use.In recent years, people have invented " three-jaw device " and have been used for the dismounting that external application is taken turns in production practices, and " three-jaw device " is by the screw rod of band point, is provided with the attaching nut on screw rod, connect three radial suspension hooks compositions in the outside of nut symmetry.The root of suspension hook is adjustable." three-jaw device " is though can solve general external application wheel dismounting problem, but because this structural restriction, during dismounting the three-jaw suspension hook with unloaded wheel and contacted for point type, and the tip of screw rod withstands in the machining hole that is unloaded the wheel wheel shaft, both its tapering differences, thereby friction is big, inefficiency, also can make central pivot point produce displacement, so, axle crooked and the rapid wear problem of being unloaded wheel still can not be solved, and take turns for interference fit between bearing and wheel, the axle and the external application of getting rusty for a long time and can't dismantle at all.
Summary of the invention: the purpose of this utility model provides a kind of external application wheel stripping attachment.It is big to be mainly the friction that exists in the solution prior art, inefficiency, and the central pivot point displacement, the flexible wheel rapid wear that unloaded of axle, interference fit reaches the external application of getting rusty for a long time and takes turns the problem that can't dismantle between bearing and wheel, the axle.
Scheme of the present utility model is as described below: this utility model comprises screw rod, nut, suspension hook, is equipped with cap, also comprise cone, connecting rod, pressure bearing, loam cake and screw, it is by the bottom at screw rod the cone that is placed in screw rod and built-in pressure bearing to be set, and radially screw is set in the nut that connects on screw rod, connect two or three by connecting rod be fixed on the work pawl that the removable suspension hook on the connecting rod forms and constitute through screw symmetry radially.
The beneficial effects of the utility model: this utility model is owing to taked said structure, particularly be provided with the cone and the improved suspension hook of built-in pressure bearing, make this utility model can avoid the displacement of central pivot point effectively, solved the problem that axle is flexible, quilt is unloaded the wheel rapid wear and part external application wheel can't be dismantled up hill and dale, reduced simultaneously friction effectively, improve the serviceability rate that wheel shaft machining hole and screw rod are equipped with cap relatively, shortened the time of changing wheel greatly, significantly improved operating efficiency.And have simple in structure, easy to use, flexible operation, maintenance is timely, adaptability is strong, be convenient to advantages such as popularization.
Description of drawings:
Fig. 1 is the overall structure front view of external application wheel stripping attachment;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the nut radial cross-section of external application wheel stripping attachment.
The specific embodiment: by the external application wheel stripping attachment of Fig. 1-shown in Figure 3 is that cone 2, top that the bottom is provided with built-in pressure bearing 1 are placed cone 2 internal pressure bearings 1 centre bore for the screw rod 4 that is equipped with cap 3, and cone 2 tops are that loam cake 5 is fixing through screw 6.The nut 7 that is threaded on the screw rod 3, nut 7 radially be provided with respectively 180 ° with 120 ° of two groups of corresponding screwed holes, and connect two or three by connecting rod 8 be fixed on the work pawl that the removable suspension hook 9 on the connecting rod 8 forms and constitute by this screwed hole symmetry.Its suspension hook 9 is a right angle hook, and it is circular arc that the end 10 of hook promptly points to inboard part.Its top is enclosed within on the connecting rod 8, and can regulate fixing in the optional position on the connecting rod 8.When dismounting external application wheel, the summit of cone 2 should be aimed at the machining hole of wheel shaft, because the taper design of cone 2 and the machining hole of wheel shaft match, can avoid the central pivot point displacement.Regulating the position of suspension hook 9 on connecting rod 8 makes it suitable with the external diameter that is unloaded wheel, be stuck in simultaneously on the external diameter that is unloaded wheel and and hold up its integral body, and the end 10 of suspension hook 9 is near wheel shaft, revolving fully with instrument, cap 3 rotates screw rod 4, the nut 7 that is connected on the screw rod 4 is moved downward relatively, unloaded that wheel is upwards carried and with its smooth dismounting thereby drive.Since be provided with pressure bearing in the cone, not only laborsaving but also convenient and swift during dismounting.Can also avoid axle flexible, unloaded problem such as wheel rapid wear etc., reliably realize goal of the invention.
