Description

A kind of GE motor flange extracting tool

Technical field

The utility model belongs to plant equipment field, is specifically related to a kind of GE motor flange extracting tool.

Background technology

GE(is AM General) motor is a kind of equipment of commonly using. Existing GE motor flange dismounting mode is to utilize pressure oil pump that hydraulic oil is sprayed in the oilhole in axle center. Specific works principle as shown in Figure 1; working solution force feed enters booster pump 19 through inflow pipeline 20 from oil drum; after increasing, booster pump pressure enters conversion head 17 from flowline 18; enter motor shaft 15 oil canals 16 from conversion head again; arrive again the contact-making surface 17 of motor shaft 15 and flange 14; make the flange inner surface of contact-making surface be subject to a normal force F; this normal force F have two action effects (the firstth, make flange 14 inwalls be subject to vertically outside power F2; this makes the elasticity change diametrically of flange diameter of bore large, makes original interference fit become matched in clearance; The secondth, make flange 14 be subject to the power F1 of axial direction). In the situation that pressure continues to increase, F1 and F2 become greatly simultaneously, thereby make flange 14 from motor shaft 15 separation that comes off, and reach the object of dismounting.

The equipment that this method for dismounting needs has booster pump, hydraulic oil, oil drum, turnover oil-piping, conversion head. Many, the heaviness of equipment and the inconvenient operation that need; In addition, need in this way to prepare separately hydraulic oil owing to adopting, and hydraulic oil does not allow to carry by air time, need delivery fortune or buy to on-the-spot, and the place that need to dismantle GE motor flange is often very remote, while again arriving remote local operation, hydraulic oil is also inconvenient to buy, and affects the carrying out of dismantlement work.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in detail.

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated. Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.

Embodiment

As shown in Figure 2, a kind of GE motor flange extracting tool, comprise connected successively nozzle 1, front end skull 2, shell ring 5 and rear end skull 7, nozzle 1, front end skull 2, the centre of shell ring 5 and rear end skull 7 offers cavity, front end skull 2, the cavity of shell ring 5 and rear end skull 7 forms working chamber 9, in the cavity of shell ring 5, be provided with piston 6, also be provided with the thrust screw rod 8 corresponding with piston 6, thrust screw rod 8 inserts from the termination of rear end skull 7, in the cavity of nozzle 1, be provided with spring 10 and sealing steel ball 11, and be provided with soket head cap screw 12 with through hole as securing member at the other end of spring 10, soket head cap screw 12 is concordant with nozzle 1 termination,

On front end skull 2, be provided with seam concave station, and on shell ring 5, be provided with the seam groove corresponding with described seam concave station, described front end skull 2 is connected by hexagon socket head cap screw 3 with shell ring 5, and junction is coated with one deck glass cement.

When assembling, as shown in Figure 3, first assembling nozzle 1, first puts into the cavity of the 10mm of nozzle 1 by sealing steel ball 11, then spring 10 is packed in this cavity, is finally screwed into M12 soket head cap screw 12 with holes at the front end of nozzle 1;

Refill and join front end skull 2 and shell ring 5, as shown in Figure 4, first the seam boss of the diameter 40mm on front end skull 2 is tapped down in the seam groove of shell ring 5, and bolt hole is alignd.
