Detailed Description

The embodiments of the present invention will be described in detail below, and the present embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.

Fig. 2 is a cross-sectional view of a bearing shield according to an embodiment of the present invention.

Referring to fig. 2, the bearing sheath of the present embodiment includes: a sheath body 12, a central position of which is provided with a through hole for accommodating the bearing 11. The top opening of the sheath main body 12 is a tightening top opening 13, the outer diameter of the tightening top opening 13 is smaller than the outer diameter of the adjacent part of the tightening top opening, so that the installation of the tool is facilitated, the tool can be used for installing and disassembling the bearing sheath, and the tool is simple and convenient, saves labor and saves time.

In a preferred embodiment, the edge of the top opening of the main body of the sheath is further provided with a tangent plane fitting structure 14, as shown in fig. 3, the structure is a group of symmetrical and parallel tangent plane fitting structures consisting of fitting planes with the depth of 15mm-25mm and the width of 90mm, and the structure is a structure facilitating the fitting of the bearing shield and the mounting tool, so that the mounting and dismounting of the bearing sheath are more convenient. In a preferred embodiment, the main body of the sheath is further provided with positioning holes 15 and 16, as shown in fig. 4, two positioning holes are taken as an example in this embodiment, and the positioning holes are used for maintaining the position between the sheath and the bearing.
