Description

A bearing disassembly tool with anti-wear coating

Technical Field

The utility model relates to the field of bearing disassembly, in particular to a bearing disassembly tool with an anti-wear coating.

Background Art

The main functions of bearings are to support mechanical rotating bodies, ensure the working position and accuracy of shafts and transmission parts on shafts, reduce friction and wear, and bear loads.

For the disassembly of bearings, existing disassembly methods include the impact unloading method, which uses the impact energy generated by hammering a copper rod or soft iron to remove the bearing, and the pulling method, which uses a special puller for disassembly. However, existing pullers mostly use claws to hook the bottom surface of the bearing. This method only forms a small number of force points on the bearing. If the claw is separated from the bearing surface, the same problems as the impact unloading method will occur. When the external force is applied unreasonably, it is very likely to cause the bearing to break and cause metal fragments to splash, which is dangerous.

Utility Model Content

The technical problem to be solved by the utility model is that when using the existing puller to dismantle the tapered bearing, if the external force is applied unreasonably, the bearing will be broken and metal fragments will splash, which will bring danger.

In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a bearing disassembly tool with an anti-wear coating, including a fixed plate, a threaded cylinder is slidably installed inside the fixed plate, a circular plate is installed on the side of the threaded cylinder, a connecting rod is penetrated inside the circular plate, one end of the connecting rod is installed with an inner tapered sleeve, the inner tapered sleeve is connected to the outer tapered sleeve by means of bolts, two conical pieces with inner walls coated with anti-wear coating are slidably installed inside the outer tapered sleeve, the inner walls of the two conical pieces are respectively clamped with a pull rod whose one end extends to the outside of the outer tapered sleeve, a clamping plate is installed on the outer surface of the pull rod, four mutually symmetrical rocking rods are hinged on the side of the outer tapered sleeve, and the bottom ends of the four rocking rods are all fixedly axially mounted with a splint, a slide plate is slidably installed inside one end of the splint, a baffle is hinged on the top of the slide plate, a magnet is installed on the inner side surface of the rocking rod near the bottom end, and a fixed seat is installed at the bottom of the inner part of the outer tapered sleeve away from the clamping plate.

The utility model is further configured that the two conical sheets cooperate to form a complete cone and the inner wall array is provided with a plurality of rectangular grooves.

The utility model is further configured that the side surface of the baffle is connected to the top surface of the slide plate through a spring.

The utility model is further configured that a groove matching the rotation position of the magnet and having an iron block inside is opened on the side surface of the outer cone sleeve.

The utility model is further configured that the outer surface of the pull rod is sleeved with a spring located between the clamping plate and the fixing seat.

The utility model is further configured that a cushion block is installed on the top of the swing rod.

The beneficial effects of the utility model are as follows:

1. The utility model provides components, and when disassembling, the conical piece cooperates with the clamping plate to wrap the conical gear, the clamping plate contacts the bottom surface of the conical bearing, and the rectangular groove surface contacts the bottom surface of the rotor. There are more stress points on the conical bearing, and the stress is more uniform, so that the conical bearing can be disassembled more safely;

2. The arrangement of the pull rod of the utility model and the coordination between related components ensure that the tapered piece always maintains a good fit with the tapered bearing during the disassembly process, avoiding the danger of metal fragments splashing due to the bearing breaking during the disassembly process. After the disassembly is completed, the components can be automatically reset, which is more flexible to use.

DETAILED DESCRIPTION

The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

Please refer to Figures 1 to 3. A bearing removal tool with an anti-wear coating includes a fixed plate 1, a threaded tube 2 is slidably installed inside the fixed plate 1, a disc 3 is installed on the side of the threaded tube 2, a connecting rod 4 passes through the inside of the disc 3, an inner tapered sleeve 5 is installed at one end of the connecting rod 4, the inner tapered sleeve 5 is connected to an outer tapered sleeve 6 by means of bolts, two conical pieces 9 with inner walls coated with an anti-wear coating are slidably installed inside the outer tapered sleeve 6, the two conical pieces 9 cooperate to form a complete cone and the inner wall array is provided with a plurality of rectangular grooves, combined with the shape of the conical piece 9 and the grooves, the conical piece 9 can fit the conical bearing used to wrap the conical bearing.

The inner walls of the two conical pieces 9 are each clamped with a pull rod 10 whose one end extends to the outside of the outer cone sleeve 6, and a clamping plate 11 is installed on the outer surface of the pull rod 10. The side of the outer cone sleeve 6 is hinged with four mutually symmetrical swing rods 12, and the bottom ends of the four swing rods 12 are all fixedly rotatably mounted with a clamping plate 13. The side of the swing rod 12 is provided with a groove matching the baffle 8. A slide plate 7 is slidably installed inside one end of the clamping plate 13, and a baffle 8 is hinged on the top of the slide plate 7. The side of the baffle 8 is connected to the top surface of the slide plate 7 through a spring. As shown in FIG. 2, the baffle 8 is moved under the action of the spring elastic force. Down, it still maintains contact with the bottom surface of the tapered bearing after flipping, a magnet 14 is installed on the inner side of the rocker arm 12 near the bottom end, and a groove with an iron block inside is opened on the side of the outer cone sleeve 6, which matches the rotation position of the magnet 14. The position of the rocker arm 12 after rotation is fixed by the magnetic force of the magnet 14, and a fixing seat 15 is installed at the bottom of the outer cone sleeve 6 away from the clamping plate 11. A spring located between the clamping plate 11 and the fixing seat 15 is sleeved on the outer surface of the pull rod 10. With the help of the elastic force of the spring, when the rocker arm 12 is no longer in contact with the pull rod 10, the pull rod 10 can be reset.

When the utility model is in use, the swing rod 12 is rotated to the outside of the outer tapered sleeve 6, and then the conical sheet 9 is covered on the conical bearing, and the rotor of the conical bearing can be placed in the groove set on the conical sheet 9, and then the swing rod 12 is rotated to allow the magnet 14 to attract the iron block set on the side of the outer tapered sleeve 6, and then the position of the swing rod 12 is fixed. At this time, since the swing rod 12 is in contact with one end of the pull rod 10, the pull rod 10 pushes the conical sheet 9 to the surface of the conical bearing, and then the baffle 8 is turned over and the clamping plate 13 is rotated, and the baffle 8 is adjusted to the gap between the inner ring of the conical bearing and the mounting shaft by sliding the slide plate 12, so that the clamping plate 13 and the baffle 8 can contact the bottom surface of the conical bearing, thereby cooperating with the conical sheet 9 to wrap the conical bearing, and finally the fixed plate 1 is fixed, and the conical bearing can be disassembled by the provided threaded tube 2 in cooperation with the threaded rod.
