SU1222530A1 - Power puller - Google Patents

Description

FIELD OF THE INVENTION The invention relates to mechanical engineering, in particular, to devices for the removal of parts pressed against the shaft.

The purpose of the invention is to improve performance by eliminating damage to the removed part.

FIG. 1 shows the puller, general view; in fig. 2 t is the same, top view.

The puller contains the yoke 1 with the central axial 2 and the radial 3 holes, the power screw 4 placed in the central axial hole 2, the clamps 5 fixed on the yoke 1 with the possibility of radial movement relative to the power screw 4, the nut 6 interacting with the power screw 4, and the L-shaped bracket 7, which is rigidly connected to the traversal one. In the shelf of the L-shaped bracket 7, an opening 8 is made, through which the power screw 4 is passed. The stripper is also provided with ball bearings: (guides 9, by means of which the ends of the nut 6 rests on the traverse 1 and the shelf of the L-shaped bracket 7, and the grippers 5 are made up of two parts, having differently directed threads and interconnected by the coupling 10.

The sleeve 11 is rigidly fixed to the cross member 1 on the opposite side of the L-shaped bracket 7. In the power screw 4, a longitudinal groove 12 is made, and in the sleeve 11 there is a threaded hole in which a retainer 13 is installed, in contact with the groove 12

power screw 4.

The puller works as follows.

The power screw 4 is passed through the opening 8 in the shelf of the L-shaped bracket 7 and the nut 6, through the opening 2 of the crosshead 1, the sleeve 11 and fix it with the latch 13. The gripper 5 is mounted on the outer size of the slot-shaped part 14 so that the protrusions of the grippers 5 cover detail 14. The length of each of the claws 5 is adjusted by clutch 10. Then, rotating the nut 6, move the power screw 4 until it touches the shaft 15 on which the removable part 14 is seated. Then, continuing to rotate the nut 6 again, create a force on the power screw 4, resulting in item 14. removed from in ala 15.

Supplying the puller with an L-shaped bracket and ball guides, as well as the implementation of two-part grippers with multidirectional threads and coupled to each other, will eliminate damage to the removed part and increase productivity.
