Abstract

The utility model relates to a ware is drawn to bearing of civil aviation generator rotor, including clamp, overcoat rand, the vertical ejector pin that sets up in the clamp outside the clamp, the rand is along clamp relative slip, be equipped with the guide block in the clamp, the ejector pin passes the guide block and rotates relatively between the two, end screw thread connection has the nut under the ejector pin, the nut passes through the gangpin and is connected with the guide block, nut one end is connected with the handle. The utility model adopts the clamp with the split structure, the guide block, the nut, the ejector rod and the handle; the bearing outer ring is wrapped by the clamp, the ejector rod props against the bearing inner shaft, and the nut and the ejector rod perform relative spiral rotation so as to pull out the bearing outer ring; the tool effectively solves the problem that the bearing clamp cannot be detached due to the narrow space at the bottom of the bearing, and is suitable for the condition that the bearing and the connecting rod are blocked to cause that the clamp cannot be detached due to insufficient force when the clamp is detached from the bottom.

Description

Bearing puller of civil aviation generator rotor

Technical Field

The utility model relates to a send out the bearing and demolish technical field, specifically be a ware is drawn to bearing of civil aviation generator rotor.

Background

At present, the common bearing pullers include a puller type puller and an expansion sleeve type puller. Among them, the drawbench is the most commonly used, and there are mature series products at present, but the drawbench is only suitable for the parts on the bearing which must have a projection. The expansion-sleeve type puller is used for removing the bearing by expanding the expansion sleeve and generating friction force between the expansion sleeve and the bearing, and is commonly used for removing a single bearing. However, neither the puller type drawing device nor the expanding type drawing device can be applied to the situation that the bearing cannot be removed from the bottom due to the small gap at the bottom of the bearing, and the situation that the clamp cannot be removed due to the insufficient force of the clamp when the bearing and the connecting rod are locked.

Disclosure of Invention

In order to solve the technical problem, the utility model provides a ware is drawn to bearing of civil aviation generator rotor.

The utility model discloses the technical problem that will solve adopts following technical scheme to realize:

the utility model provides a ware is drawn to bearing of civil aviation generator rotor, includes clamp, overcoat rand, the vertical ejector pin that sets up in the clamp outside the clamp, the rand is along clamp relative slip, be equipped with the guide block in the clamp, the ejector pin passes guide block and relative rotation between the two, tip threaded connection has the nut under the ejector pin, the nut passes through the gangpin and is connected with the guide block, nut one end is connected with the handle.

As a further improvement, the upper end of the clamp is of a split structure, and the bottom of the clamp is of an inner buckle structure.

As a further improvement of the utility model, the upper end of the ejector rod is connected with a bush through a thread.

The utility model has the advantages that:

the utility model adopts the clamp with the split structure, the guide block, the nut, the ejector rod and the handle; the bearing outer ring is wrapped by the clamp, the ejector rod props against the bearing inner shaft, and the nut and the ejector rod perform relative spiral rotation so as to pull out the bearing outer ring; the tool effectively solves the problem that the bearing clamp cannot be detached due to the narrow space at the bottom of the bearing, and is suitable for the condition that the bearing and the connecting rod are blocked to cause that the clamp cannot be detached due to insufficient force when the clamp is detached from the bottom.

Drawings

The invention will be further described with reference to the following figures and examples:

FIG. 1 is a schematic view of the interior of the present invention;

fig. 2 is an external top view of the present invention;

fig. 3 is a schematic view of the left side of the outside of the present invention.

Detailed Description

In order to make the technical means, creation features, achievement purposes and effects of the present invention easy to understand, the present invention will be further explained with reference to the accompanying drawings and embodiments.

As shown in fig. 1 to 3, the bearing puller of the civil aviation generator rotor comprises a clamp 1, a collar 2 sleeved outside the clamp 1, a mandril 6 arranged inside the clamp 1, a nut 4 in threaded connection with the mandril 6, and a handle 7 connected with the right side of the nut 4; the upper end of clamp 1 is the formula structure of formula of split, bottom for interior knot, 1 relative slip of clamp can be followed to rand 2, and it realizes entangling and loosening clamp 1 through relative slip, be equipped with in clamp 1 rather than the guide block 3 of knot formula structure bottom adaptation, ejector pin 6 passes and can rotate relatively rather than in following guide block 3, be connected through linkage pin 5 between guide block 3 and the nut 4 to make there is not relative motion between the two, 6 upper end of ejector pin is connected with bush 8 through threaded connection's mode.

The tool can be used for the condition that the bearing bottom clearance is small so that the bearing cannot be detached from the bottom and the condition that the bearing and the connecting rod are blocked so that the force of the clamp cannot be detached from the bottom. During the use, this frock lives the bearing inner race through the split type structure parcel of clamp 1 upper end, the axle in the bearing is withstood to 6 upper ends of ejector pin simultaneously, then entangle clamp 1 with rand 2, thereby it is fixed to make the bearing inner race to be cliied, clockwise turning handle 7 is then, rotation through handle 7 drives nut 4 synchronous rotation, thereby make nut 4 outwards remove along the axis of ejector pin 6, in addition nut 4 links as an organic whole through linkage round pin 5 with guide block 3, guide block 3 and clamp 1 block, thereby will clamp 1 and outwards pull out with the bearing inner race.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and what is described in the specification are the principles of the present invention, and that various changes and modifications may be made without departing from the spirit and scope of the present invention, and these changes and modifications are intended to fall within the scope of the present invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
