Technical Field

The utility model relates to the field of electric vehicles, in particular to a disassembling tool for an electric vehicle bearing.

Background

The bearing is an important part in modern mechanical equipment, and has the main functions of supporting a mechanical rotating body, reducing the friction coefficient in the motion process and ensuring the rotation precision of the mechanical rotating body, while the bearing sleeve is widely applied to places with light load and convenient disassembly, and a plurality of bearings can be difficult to assemble and disassemble, particularly the disassembly of the bearings in the wheels of the electric vehicle is limited by conditions, and the bearings are difficult to disassemble by using a common tool.

Disclosure of Invention

In order to solve the existing problems, the utility model provides a disassembling tool for an electric vehicle bearing. The utility model is realized by the following technical scheme.

The utility model provides a dismounting tool of electric motor car bearing, includes bearing fixed cover, sleeve and screw rod;

the bearing fixing sleeve is of a cylindrical hollow structure; the front end of the bearing fixing sleeve is provided with a first bearing inlet and a second bearing inlet which are communicated with each other; the inner wall of the bottom end of the bearing fixing sleeve is provided with an internal thread, the outer wall of the front end of the sleeve is provided with an external thread, and the bottom end of the bearing fixing sleeve is in threaded connection with the front end of the sleeve; the sleeve is of a cylindrical hollow structure; an opening is formed in the outer wall of one side of the sleeve in a penetrating manner; the screw rod is in threaded connection with the sleeve.

Further, the opening of the first bearing access port is smaller than the opening of the second bearing access port.

Further, the bottom welding of screw rod is equipped with hexagon nut.

The utility model has the beneficial effects that: the utility model has novel design and reasonable structure, can improve the maintenance efficiency of the wheel bearing of the electric vehicle, solves the difficult problem that the bearing or the bridge shaft is difficult to replace after being damaged, has no damage to the bridge shaft and the bearing, can greatly reduce the labor intensity of maintenance personnel, and can be popularized and applied in a large area.

Detailed Description

The technical scheme of the utility model is described in more detail and completely below with reference to the accompanying drawings.

In the description of the present utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings are merely for convenience in describing the present utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present utility model, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.

The embodiment 1 is a disassembly tool for an electric vehicle bearing, which comprises a bearing fixing sleeve 1, a sleeve 2 and a screw 3;

the bearing fixing sleeve 1 is of a cylindrical hollow structure, a first bearing inlet 101 and a second bearing inlet 102 which are communicated with each other are arranged at the front end of the bearing fixing sleeve 1, and the opening of the first bearing inlet 101 is smaller than that of the second bearing inlet 102;

the inner wall of the bottom end of the bearing fixing sleeve 1 is provided with an internal thread, the outer wall of the front end of the sleeve 2 is provided with an external thread, the bottom end of the bearing fixing sleeve 1 is in threaded connection with the front end of the sleeve 2, the sleeve 2 is of a cylindrical hollow structure, and the outer wall of one side of the sleeve 2 is provided with an opening 201 in a penetrating manner;

the screw rod 3 is in threaded connection with the sleeve 2, and a hexagonal nut 301 is welded at the bottom end of the screw rod 3.

The specific using process comprises the following steps: the bearing fixed sleeve 1 is fixedly sleeved with the bearing through the bearing inlet, then the bearing fixed sleeve 1 is in threaded connection with the sleeve 2, the screw 3 enters from the bottom end of the sleeve 2, the hexagonal nut 301 welded at the bottom end of the screw 3 is used for enabling a spanner to apply force to rotate, along with the rotation, the screw 3 props against the bridge shaft bearing, the screw 3 is rotated, and the bearing is detached from the bridge shaft bearing.

In the present utility model, unless explicitly specified and limited otherwise, the terms "mounted," "connected," "secured," and the like are to be construed broadly and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements.
