The novel bearing is characterized in that a roller shaft is arranged in the bearing inner ring in a clamping mode, a trapezoidal screw is arranged at the upper end of the roller shaft, the lower end of the trapezoidal screw is of a pointed structure, the trapezoidal screw is overlapped with the axis of the roller shaft, the trapezoidal screw is screwed with a trapezoidal threaded hole in the center of a U-shaped transverse fixing support, the bearing inner ring is fixed by using a two-half fixing base, a base meshing convex head machined on the inner side of the two-half fixing base is meshed with a groove contact surface on the outer side of the bearing inner ring, and the end of the U-shaped transverse fixing support is fixed with the end of the two-half fixing base through a fixing through shaft hole and a pin shaft. The utility model has simple structure and convenient operation, can be rapidly disassembled even if the bearing is damaged and only the bearing inner ring is left, does not need to use electric welding, can improve the working efficiency, reduce the labor intensity and reduce the risks of safety and fire hazards.

Description

Bearing take-out device

Technical Field

The utility model relates to the field of maintenance tools, in particular to a bearing taking-out device which is mainly used for disassembling and assembling a bearing under the condition of insufficient maintenance space.

Background

As is well known, in various production enterprises, the manual transportation is slowly banned by an automatic conveying line for the transportation of articles, so that the labor force is liberated, and the production efficiency is improved. The power output of the conveying line is rotated by a motor to drive a chain to pull the roller shaft of the conveying line to roll, thereby achieving the purpose of conveying articles, and the maintenance work of conveying line equipment is done at ordinary times to be the basis for improving the production efficiency. In the running process of the conveying line, along with the increase of running time, the roll shaft and the bearing are frequently stressed, and the bearing of the conveying line is easy to damage. Because the bearing is installed on the roller, the interval between bearing and the roller is less, and ordinary dismantlement bearing instrument can't use, and maintenance personal can only violently tear open when changing the bearing, and special circumstances need use angle grinder or gas cutting to dismantle, not only influence maintenance efficiency, and have great safety and fire control hidden danger.

Disclosure of Invention

In order to overcome the defects of the prior art, the utility model provides the bearing taking-out device which can improve the working efficiency of maintenance personnel, ensure normal production and reduce the safety and fire-fighting hidden trouble.

The technical scheme adopted for solving the technical problems is as follows: the utility model provides a bearing take-out device, is equipped with the roller, the roller cartridge is equipped with trapezoidal lead screw in the bearing inner race, characterized by, the roller upper end is equipped with trapezoidal lead screw, trapezoidal lead screw lower extreme be sharp structure, trapezoidal lead screw and the axis coincidence of roller, trapezoidal lead screw and the trapezoidal screw hole at the center of the horizontal fixed bolster of U-shaped are in the same place soon, use two halves type unable adjustment base to fix the bearing inner race, the base meshing protruding head of the inboard processing of two halves type unable adjustment base meshes with the slot contact surface in the bearing inner race outside mutually, U-shaped horizontal fixed bolster tip is fixed through fixed shaft hole and round pin axle with two halves type unable adjustment base tip.

The utility model has the advantages of simple structure, convenient operation, quick disassembly even if the bearing is damaged and only the bearing inner ring is left, no electric welding is needed, the working efficiency can be improved, the labor intensity is reduced, and the risks of safety and fire hazards are reduced.

Drawings

The utility model will be further described with reference to the drawings and examples.

FIG. 1 is a schematic diagram of the structure of the present utility model.

In the figure, a trapezoidal screw rod, a 2U-shaped transverse fixing support, a 3 roll shaft, a 4 bearing inner ring, a 5 two-half type fixing base, a 6 base meshing raised head, a 7 trapezoidal threaded hole and a 8 fixed through shaft hole.

Detailed Description

In the figure, a roll shaft 3 is arranged, the roll shaft 3 is clamped in a bearing inner ring 4, a trapezoidal screw rod 1 is arranged at the upper end part of the roll shaft 3, the lower end of the trapezoidal screw rod 1 is of a pointed structure, the trapezoidal screw rod 1 coincides with the axis of the roll shaft 3, the trapezoidal screw rod 1 is screwed together with a trapezoidal threaded hole 7 in the center of a U-shaped transverse fixing support 2, an outer hexagon nut is processed at the top end of the trapezoidal screw rod 1, the bearing inner ring 4 is fixed by using a two-half fixing base 5, a base meshing raised head 6 processed at the inner side of the two-half fixing base 5 is meshed with a groove contact surface at the outer side of the bearing inner ring 4, and the end part of the U-shaped transverse fixing support 2 and the end part of the two-half fixing base 5 are fixed through a fixing through shaft hole 8 and a pin shaft.

When the bearing is damaged and only the bearing inner ring 4 is left, the bearing inner side and the transportation line cross beam have smaller interval distance, so that a common tool cannot be used, the bearing inner ring 4 is fixed by using the two-half type fixing base 5, and the base engagement raised head 6 processed on the inner side of the two-half type fixing base 5 is engaged with the groove contact surface on the outer side of the bearing inner ring 4. The U-shaped transverse fixing support 2 and the two-half fixing base 5 are fixed through the fixing through shaft holes 8. Finally, the outer hexagon nut at the top end of the trapezoidal screw 1 is twisted by using a wrench, and the trapezoidal screw 1 is used for supporting the roll shaft 3 in the whole process, so that the bearing inner ring 4 and the roll shaft 3 can be slowly separated, and the purpose of bearing disassembly is achieved.

Claims
