Abstract
A booster pump bearing outer ring liftout attachment, comprises board-like pulling claw, anti-expansion set and step axle.It is characterized in that board-like pulling claw is divided into two semicircles, respectively there are three steps, the effect of small stair is to coordinate with anti-expansion set endoporus, avoid stressed the opening of board-like pulling claw to cause board-like pulling claw to come off, intermediate step outside diameter is consistent with bearing outer ring endoporus, and large step (being claw) catches on bearing outer ring end face to bearing outer ring is pulled out; Step axle can supporting plate type pulling claw in case it shrinks, can when work, with jack, withstand its end face again, bearing outer ring is ejected.The utility model coordinates jack to use can easily bearing outer ring to be ejected, simple in structure, be convenient to manufacture.Be mainly used in ejecting booster pump bearing outer ring.
Description
One, technical field:
The utility model is a kind of instrument, specifically a kind of instrument that coordinates jack to use and can easily booster pump bearing outer ring be ejected.
Two, background technology:
Booster pump is in field produces, to be used for to underground flooding, to improve strata pressure, increases the capital equipment of crude output.And after booster pump running certain hour, must maintain or keep in repair, sometimes need to carry out the replacing of bearing.What booster pump used is taper roll bearing, its outer ring is mounted on bearing (ball) cover, because bearing outer ring and end cap are interference fit, be difficult to take out, all with flame cutting, then bearing outer ring to be cut off and taken out in the past, easily make bearing (ball) cover temperature distortion, cause booster pump noise to increase, shorten booster pump service life; Some occasion is forbidden to get angry simultaneously.For improvement situation, need to develop a kind of booster pump bearing outer ring liftout attachment
Three, summary of the invention:
The purpose of this utility model is exactly the problem existing in booster pump maintenance, designs a kind of simple in structurely, is convenient to manufacture, and the instrument that can easily booster pump bearing outer ring be ejected, to improve maintenance condition, guarantees safety in production.
A kind of booster pump bearing outer ring liftout attachment described in the utility model, comprises board-like pulling claw, anti-expansion set and step axle.Board-like pulling claw is divided into two semicircles, respectively there are three steps, the effect of small stair is to coordinate with anti-expansion set endoporus, avoid stressed the opening of board-like pulling claw to cause board-like pulling claw to come off, intermediate step outside diameter is consistent with bearing outer ring endoporus, and large step (being claw) catches on bearing outer ring end face to bearing outer ring is pulled out.
Feature of the present utility model is: simple in structure, be convenient to manufacture, coordinating jack to use can eject booster pump bearing outer ring easily, without getting angry.
Four, accompanying drawing explanation:
Accompanying drawing 1 is a kind of operation chart of the present utility model
Accompanying drawing 2 is front views of the board-like pulling claw of the utility model
Accompanying drawing 3 is left views of the board-like pulling claw of the utility model
Five, the specific embodiment:
With reference to accompanying drawing 1, a kind of booster pump bearing outer ring liftout attachment, comprises board-like pulling claw 2, anti-expansion set 1 and step axle 3.Board-like pulling claw 2 is divided into two semicircles, respectively there are three steps, the effect of small stair is to coordinate with anti-expansion set 1 endoporus, avoid stressed the opening of board-like pulling claw 2 to cause board-like pulling claw 2 to come off, intermediate step outside diameter is consistent with bearing outer ring 5 endoporus, and large step (being claw) catches on bearing outer ring 5 end faces to bearing outer ring 5 is pulled out.
During operation, first two parts of board-like pulling claw 2 are stuck in to the gap between bearing outer ring 5 and bearing (ball) cover 6, then step axle 3 is inserted to the endoporus of board-like pulling claw 2, finally anti-expansion set 1 is enclosed within on the cylindrical of board-like pulling claw 2, jack 4 is withstood on the end face of step axle 3, utilize the screwed hole on bearing (ball) cover 6, coordinate screw rod 7 and baffle plate 8 that bearing outer ring 5 is ejected.
Claims (2)
1. a booster pump bearing outer ring liftout attachment, comprise board-like pulling claw, anti-expansion set and step axle, board-like pulling claw is divided into two semicircles, respectively there are three steps, the effect of small stair is to coordinate with anti-expansion set endoporus, avoid stressed the opening of board-like pulling claw to cause board-like pulling claw to come off, intermediate step outside diameter is consistent with bearing outer ring endoporus, and large step catches on bearing outer ring end face to bearing outer ring is pulled out.
2. booster pump bearing outer ring liftout attachment according to claim 1, is characterized in that anti-expansion set is the internal diameter annulus consistent with board-like pulling claw external diameter, and its effect is to come off while preventing board-like pulling claw work.
