Description
Technical Field
The utility model relates to the technical field of valves, in particular to a tool for mounting a bearing.
Background
The existing bearing mounting method is different due to bearing structure, fit and conditions, generally, the bearing rotates mostly, and therefore, an inner ring needs interference fit. Cylindrical hole bearing, press-in by multi-purpose press or hot-packing method. In the case of a taper hole, the taper hole is directly installed on a taper shaft or installed by a sleeve. When the outer ring is mounted on the shell, the outer ring is generally in clearance fit, has interference, and is generally pressed in by a press machine, or a shrink fit method of mounting after cooling is also provided. In the case of shrink-fitting mounting using dry ice as a coolant, moisture in the air condenses on the surface of the bearing. Therefore, a proper anti-rust measure is needed, the direction of the mounted part is limited by the press-in mounting method, the special structure of the butterfly valve is inconvenient to press in vertically, the valve is inconvenient to fix in a vertical press-in mode, and potential safety hazards exist.
Disclosure of Invention
The utility model provides a tool for mounting a bearing, which overcomes the defects of the prior art, utilizes the design of an oil pump and an oil inlet pipe as a power source to drive an actuating mechanism, can transversely and longitudinally pull in the bearing, is simple and convenient to operate, saves labor, has high efficiency and improves the working efficiency.
In order to achieve the above object, a tool for bearing installation is designed, which comprises an actuating mechanism, and is characterized in that: the upper part of the actuating mechanism is of a rod-shaped structure, the lower part of the actuating mechanism is of a cavity structure, the upper part of the cavity positioned at the lower part of the actuating mechanism is connected with an upper oil inlet pipe, and the lower part of the cavity positioned at the lower part of the actuating mechanism is connected with a lower oil inlet pipe; and a nut is arranged at the top of the actuating mechanism.
The top of the rod-shaped structure at the upper part of the actuating mechanism is in a step shape.
The actuating mechanism is of a piston structure.
The upper oil inlet pipe and the lower oil inlet pipe are respectively connected with an oil pump.
Compared with the prior art, the tool for mounting the bearing provided by the utility model has the advantages that the design of the oil pump and the oil inlet pipe is used as a power source to drive the actuating mechanism, the bearing can be transversely and longitudinally pulled in, the operation is simple and convenient, the labor is saved, the efficiency is high, and the working efficiency is improved.
Drawings
FIG. 1 is a schematic view of the structure of the present invention.
Referring to fig. 1, 1 is an actuating mechanism, 2 is a nut, 3 is a bearing sleeve, 4 is a bearing, 5 is a part, 6 is an upper oil inlet pipe, and 7 is a lower oil inlet pipe.
Detailed Description
The utility model is further illustrated below with reference to the accompanying drawings.
As shown in fig. 1, the upper part of the actuator 1 is a rod-shaped structure, the lower part of the actuator 1 is a cavity-shaped structure, the upper part of the cavity at the lower part of the actuator 1 is connected with an upper oil inlet pipe 6, and the lower part of the cavity at the lower part of the actuator 1 is connected with a lower oil inlet pipe 7; the top of the actuating mechanism 1 is provided with a nut 2.
The top of the upper rod-shaped structure of the actuator 1 is stepped.
The actuator 1 is of a piston type construction.
The upper oil inlet pipe 6 and the lower oil inlet pipe 7 are respectively connected with an oil pump.
The operation process of the utility model is as follows: firstly, an upper oil inlet pipe 6 and a lower oil inlet pipe 7 are arranged on an actuating mechanism 1; secondly, the other ends of the upper oil inlet pipe 6 and the lower oil inlet pipe 7 are connected with an oil pump; thirdly, fixing the actuating mechanism 1 and the part 5 by bolts; fourthly, mounting the bearing 4 on the bearing sleeve 3 and fixing the bearing with the actuating mechanism 1 by using the nut 2; and fifthly, starting the oil pump, applying a pulling force to the shaft sleeve 3 by the actuating mechanism 1, and installing the bearing 4 on the part 5.
The structure of the utility model is to transversely pull in the installation of the bearing 4, the operation is simple, the labor is saved, the efficiency is high, and the working efficiency is improved. The oil pump is used as a power source to drive the actuating mechanism, the bearing can be transversely and longitudinally pulled in, the operation is simple and convenient, the labor is saved, the efficiency is high, and the working efficiency is improved.
The utility model can be used for pull-in type installation of the bearing, is not only limited to the vertical installation mode of the bearing, but also can be horizontally pulled, solves the problem that the common press-in type bearing installation tool limits the fixing mode of the parts, does not need to vertically place the parts, causes artificial heavy workload for the parts with larger appearance, and also greatly reduces the occurrence of safety accidents.
