Description
Technical field
This utility model relates to a kind of mechanical field, particularly to the provision for disengagement of a kind of bearing pin.
Background technology
Bearing pin is arranged in bore, and the method got off by dismounting hinge pin has two kinds:
One is to use manual thruster, and manual thruster includes guide rod and long-drawn-out hammer, and guide rod through threaded is fastened on
One end of bearing pin, utilizes long-drawn-out hammering to beat the tail end of guide rod by manual operation, makes bearing pin extract from bore.But, at bearing pin
In the case of serious wear causes losing circle, bearing pin is stuck with bore, utilizes manual thruster to be pulled out.
Another kind is to weld shoes in the side of bore, hydraulic jack is placed between shoes and the front end of bearing pin,
Flexible by hydraulic jack makes bearing pin extract.But, the strength of hydraulic jack is excessive, in the feelings that bearing pin and bore are stuck
Can cause the deformation of bore under condition, cause axiality to change, making cannot the new bearing pin of normal mounting.
The information being disclosed in this background section is merely intended to increase the understanding to general background of the present utility model, and
It is not construed as recognizing or imply in any form this information structure existing well known to persons skilled in the art
Technology.
Utility model content
The purpose of this utility model is to provide the provision for disengagement of a kind of bearing pin, thus overcomes existing method for dismounting at pin
Bearing pin cannot be dismantled in the case of axle is stuck with bore or be easily destroyed the axiality of bore and the defect of bearing pin cannot be installed.
For achieving the above object, this utility model provides the provision for disengagement of a kind of bearing pin, and bearing pin is arranged on pin shaft hole seat
In, the end of bearing pin is provided with screwed hole, and provision for disengagement includes: support tube, the first end opening of support tube, and the second end seal is closed,
The center of the second end of support cylinder is provided with the first through hole, and the first end of support tube is connected on the side of pin shaft hole seat；Jack,
The center of jack is provided with the second through hole, and a side of jack abuts with the end face of the second end of support tube；Guide rod,
First end of guide rod is provided with external screw thread, and guide rod sequentially passes through jack and support tube, and the spiral shell of the first end of guide rod and bearing pin
Pit connects, and the second end of guide rod is provided with locking piece.
Preferably, in technique scheme, locking piece is nut, and the second end of guide rod is provided with external screw thread, and nut passes through spiral shell
Stricture of vagina is connected on guide rod.
Preferably, in technique scheme, locking piece is straight pin, and the second end of guide rod is provided with pin-and-hole, and straight pin is installed
In pin-and-hole.
Compared with prior art, this utility model has the advantages that
Provision for disengagement of the present utility model both can guarantee that bearing pin had enough active forces to be pulled out time stuck with pin shaft hole seat
Go out, can guarantee that again pin shaft hole seat is not damaged by bearing pin, simple in construction, easy to operate, safety and stability.
Accompanying drawing explanation
