Abstract

The invention relates to a bearing disassembling device, comprising a sleeve fixed on an outside of an internal shaft the bearing. At least two hydraulic cylinders are arranged in the sleeve. The hydraulic cylinders are provided with a connecting port for hydraulic inputting, and are also provided with a plunger which is extended and is opposite to the internal side of the bearing. Therefore, the sleeve of the bearing disassembling device is fixed outside the internal shaft the bearing, and the hydraulic-pressure input connecting port is communicated with a hydraulic-pressure transmitting pipeline. The pressure is transmitted through the hydraulic system to the hydraulic cylinders arranged in the sleeve so as to drive the plunger to move outwards and to equally push the bearing to move to the outside of the shaft, thus being convenient for bearing-disassembling. A main shaft of a roller bearing is adopted as a supporting point to disassemble the bearing. The invention has simple structure and is convenient for using and disassembling, without damage to a main shaft.

Description

Shaft bearing replacer
Technical field: the present invention is the specific purpose tool that the dismounting grease is already used the rolling bearing at blank rolling mill roller two ends, dismantles the rolling bearing specific purpose tool of roll two ends and axle interference fit with hydraulic power.
Background technology: existing dismounting grease is already used the utensil of the rolling bearing at blank rolling mill roller two ends, all be to utilize big machine power mechanism or hydraulic mechanism that the rolling bearing of interference fit is unloaded from axle head, these mechanisms are huger, and must be fixed on the support or ground of crushing roll, fixing difficult.The mobile terminal of mechanism will be fixed on the rolling bearing, and is also bad fixing, if be fixed on the overcoat of rolling bearing, sometimes overcoat pulled out (squeezing) and badly can not unload whole rolling bearing.Be subjected to force direction not with axial consistent, the precision of influence axle or roller or destroy the precision of other connecting portions.
Summary of the invention:
For the rolling bearing that solves blank rolling mill roller two ends in the prior art not quick detachable, and unloading process influences the axle or the precision techniques problem of roller and other parts easily, provide a kind of easy to use, energy consumption is low, be difficult for the shaft bearing replacer of the precision of influence axle or roller and other parts.
Shaft bearing replacer of the present invention has to be fixed on the outer body of bearing inner shafts, and it is characterized in that: be distributed with at least two hydraulic cylinders in the body, hydraulic cylinder has the connector of hydraulic pressure input, hydraulic cylinder be furnished with overhanging and with the inboard relative plunger of bearing.The body of shaft bearing replacer is fixed on bearing inner shafts outer (referring to accompanying drawing) like this, the connector of hydraulic pressure input is communicated with the hydraulic pressure transfer pipeline, the hydraulic cylinder discharge pressure that in body, distributes by hydraulic system, actuation plunger outwards moves and heads on bearing with being evenly distributed and moves outside axle, conveniently unloads lower bearing.Can before dress interference rolling bearing, just shaft bearing replacer be fixed on the axle of bearing inboard, when needs dismounting bearing, just can be communicated with the transfer pipeline of hydraulic system, just can dismantle bearing.In order to dismantle bearing at the axle head that does not have to adorn shaft bearing replacer in advance whenever and wherever possible, the body that shaft bearing replacer of the present invention distributes is preferably being connected into the two halves of ring, so just can be whenever and wherever possible the body butt joint of two halves be fixedly mounted on the axle of bearing inboard, dismantle bearing, can also unload the dismounting that is used for other bearing after the use.The present invention utilizes the main shaft of roll dress bearing to do the strong point, and shaft bearing replacer is fixed on it, and pressure can act on the interior cover of rolling bearing easily, power with hydraulic pressure (or hydraulic pressure) is pulled down tearing open bearing, and it is simple in structure, and is easy to use, dismounting is convenient, does not damage main shaft.
Description of drawings: accompanying drawing has represented that shaft bearing replacer of the present invention is installed in the structural representation on the roll end bearing inner shafts.Further specify shaft bearing replacer of the present invention below in conjunction with the accompanying drawing example.
The specific embodiment:
Shaft bearing replacer of the present invention as shown in drawings has the body that is fixed on outside the bearing 3 inner side axles 4, and body is the annular casings of two semicircular ring to being connected into.Two semicircular ring are enclosed within axle 4 outer butt joints, adopt bolt 5 to pass the connecting hole of semicircular ring boss, carry out fixedly connected.Be distributed with 12 hydraulic cylinders in the body, 12 hydraulic cylinders are divided into two groups, every group of six hydraulic cylinders.Each is provided with one group of hydraulic cylinder two semicircular ring, and every group of six hydraulic cylinders circumferentially evenly distribute along semicircular ring.1, two connector of connector that two groups of hydraulic cylinders have the hydraulic pressure input respectively is communicated with two branch lines arranged side by side of hydraulic pressure transfer pipeline respectively.Each hydraulic cylinder is furnished with plunger 2,6 respectively, and the plunger outer end is overhanging and relative with bearing 3 inboards (the bearing left side of figure), withstands on the bearing inner ring left side.12 hydraulic cylinder discharge pressure liquid that the hydraulic system that is communicated with by the hydraulic pressure transfer pipeline is symmetrically distributed in body, actuation plunger outwards move and head on bearing (dextrad of figure) outside axle and move, and conveniently unload lower bearing.Axle and bearing only are subjected to the axial force of symmetry, and lowering energy-saving also can not influence spool and the precision of other parts.

Claims (2)

1. shaft bearing replacer has to be fixed on the outer body of bearing inner shafts, and it is characterized in that: be distributed with at least two hydraulic cylinders in the body, hydraulic cylinder has the connector of hydraulic pressure input, hydraulic cylinder be furnished with overhanging and with the inboard relative plunger of bearing.
2. as the said shaft bearing replacer of claim 1, it is characterized in that: body is that two semicircular ring connect by bolt to being connected into the two halves of ring.
