Description

A furnace roller bearing removal device

technical field

The utility model relates to a furnace roller maintenance device, in particular to a furnace roller bearing maintenance auxiliary device.

Background technique

During the use of the furnace roll, nodules and damage to the furnace roll will need to be replaced. The furnace roll replacement bearing disassembly is a key process with the longest time and the most labor-intensive process in the furnace roll replacement process. The number of roller replacements is relatively large. Using the traditional removal method, it usually takes 4-8 hours to remove each furnace roller bearing. The removal tools are traditional sledgehammers, crowbars, wrenches and hydraulic pullers, and many tools are needed. Easily damaged bearings and tools, low efficiency and high labor intensity.

Contents of the invention

The utility model aims to solve the above defects, and provides a furnace roller bearing dismounting device. The utility model effectively improves the working efficiency of disassembling the furnace roller bearing and reduces the labor intensity.

The utility model is achieved in the following way: a furnace roller bearing dismounting device is characterized in that it comprises:

The ring body, which includes two upper and lower semicircles, the two sides of the upper and lower semicircles are fixedly connected together by bolts, and the ring body is provided with several threaded holes along the circumference;

A rear baffle, which is a circular plate, is provided with a number of threaded holes corresponding to the ring body along the circumference;

Several screw rods pass through the rear baffle and the ring body successively from the threaded holes of the back baffle, and are fixed with nuts and bolts and the back baffle.

The roller bearing removal device also includes a hydraulic jack, which is arranged between the screw rods. the

Before pulling and unloading the bearing of the utility model, a hydraulic jack should be used to inject oil and pressure into the shaft through the oil injection hole on the end surface of the furnace roller shaft, so that the hydraulic oil fills the oil groove on the shaft surface, thereby creating a gap between the inner sleeve of the bearing and the shaft surface. In this way, it is easier to save labor during disassembly, and at the same time, it can also protect the bearing, and it is not easy to damage the bearing due to excessive pulling force. Compared with the prior art, it has the following remarkable advantages: greatly reducing the time for dismantling the furnace roller bearing; obviously reducing the labor intensity of maintenance workers; and can reduce the maintenance cost to a certain extent.

Description of drawings

Below, in conjunction with accompanying drawing, the utility model is further described:

Fig. 1 is the utility model schematic diagram.

Detailed ways

As shown in Figure 1, a kind of furnace roll bearing dismantling device, it comprises:

Ring body 1, which includes upper and lower semicircle parts, the two sides of the upper and lower semicircles are fixedly connected together by bolt nuts 5 and 7, and the ring body is provided with several threaded holes along the circumference;

A rear baffle 2, which is a circular plate, is provided with several threaded holes corresponding to the ring body along the circumference;

Some screw rods 3, it passes through tailgate and ring body successively from the threaded hole of tailgate, and it is fixed with nut bolt 4,6 and tailgate 2.

The roller bearing removal device also includes a hydraulic jack, which is arranged between the screw rods 3 (not shown in the figure).
