[0002] A bearing is an important and commonly used component in contemporary mechanical equipment. It is mainly used to support a mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotational accuracy. Bearings are divided into inner bearings and outer bearings. Generally speaking, bearings are fixed on the shaft and in the bearing housing by interference fit. However, sometimes it is necessary to disassemble the bearing. The disassembly methods include using a hammer to strike a metal rod to slowly knock out the bearing. However, this method has disadvantages such as low disassembly efficiency and inconvenient disassembly, and the bearing is easily damaged during the knocking process.

[0014] In order to make the purpose, technical solutions and advantages of the present invention clearer, the following further details the present invention in conjunction with embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0015] Aiming at the problems existing in the prior art, the present invention provides a simple device for disassembling an inner bearing. The following describes the present invention in detail with reference to the drawings.

[0016] See Figure 1 - Figure 2 As shown, the technical solution adopted in this specific implementation manner is: a simple device for disassembling an inner bearing, including a rod body 1, a limiting part 2, and a sliding cylinder 3. The rod body 1 is a round steel cylinder, and two symmetric pulling claws 11 are formed at its lower part by cutting. A certain gap 111 is formed between the two pulling claws 11. An adjusting assembly 4 is installed on one of the pulling claws 11. Through the adjusting assembly 4, the pulling claws 11 can be opened to adapt to the disassembly of inner bearings with different diameters; the limiting part 2 is welded and fixed at the top position of the rod body 1. The sliding cylinder 3 is sleeved on the upper part of the rod body 1 and can slide freely on the upper part of the rod body 1. That is, the diameter of the sliding hole of the sliding cylinder 3 should be slightly larger than the outer diameter of the rod body 1, and enough stroke should be reserved between the top of the rod body 1 and the adjusting assembly 4 for the sliding cylinder 3 to slide up and down freely.

[0017] Specifically, the adjusting component 4 includes a nut 41 and a bolt 42. The center line of the nut 41 is perpendicular to the symmetry axis of the two pawls 11 and is welded and fixed to the outer wall of the pawl 11. A through hole 112 corresponding to the screw hole of the nut 41 is formed through the pawl 11 connected to the nut 41. The bolt 42 is threadedly connected to the nut 41, and one end of the bolt 42 penetrates into the through hole 112, and its end abuts against the inner wall of the other pawl 11. The opening angle between the two pawls 11 is controlled by adjusting the length of the bolt 42 extending into the gap 111 to meet the disassembly of inner bearings with different diameters.

[0018] It should be specifically noted that the limiting part 2 can be a cross bar, and the cross bar is connected to the rod body 1 to form a "T" - shaped structure.

[0019] In addition, the limiting part 2 can also be an "X" - shaped structure, and the center of the "X" - shaped structure is welded to the upper end of the rod body 1 to achieve a fixed connection with the rod body 1. The limiting part 2 can also be a cylinder with a radius larger than the sliding hole of the sliding cylinder 3, which can limit the sliding cylinder 3. Or some other structural forms.

[0020] It should be specifically noted that an anti - slip rubber can also be installed at the contact end of the pawl 11 and the inner bearing, and anti - slip lines are provided on the contact surface of the anti - slip rubber and the inner bearing. The setting of the anti - slip rubber can increase the friction between the pawl 11 and the inner bearing. At the same time, the anti - slip rubber has a certain elasticity and can better fit the inner bearing walls with different inner diameters.

[0021] During specific use, the pawl 11 is inserted into the inner bearing, and the pawl 11 is opened by adjusting the bolt 42 so that the pawl 11 grabs the inner bearing. The reverse force can be generated by holding the sliding cylinder 3 of the device and hitting the limiting part 2 by hand, or by hitting the limiting part 2 of the device with a small hammer to generate a reverse force, so as to achieve the easy disassembly of the inner bearing with extremely high efficiency, saving time for the enterprise to resume production.

[0022] In the description of the present utility model, unless otherwise specified, the meaning of "a plurality of" is two or more; the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, which are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.

[0023] The above are only used to illustrate the technical solution of the present utility model rather than to limit it. Any other modifications or equivalent substitutions made by those of ordinary skill in the art to the technical solution of the present utility model shall be covered within the scope of the claims of the present utility model as long as they do not depart from the spirit and scope of the technical solution of the present utility model.
