Description

Technical Field

[0001] The utility model relates to the field of bearing installation, in particular to a bearing assembly tool. Background Art

[0002] Bearings are an important component in mechanical equipment. Their main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy.

[0003] In the current existing technology, there will be a mounting groove on the equipment to be installed, and the bearing will be inserted into the mounting groove. The mounting groove is in close contact with the outer ring of the bearing, and an axial hole will be formed at the bottom of the mounting groove for passing the shaft. The shaft is inserted into the middle of the bearing and is in close contact with the inner ring. During installation, the staff needs to align the bearing and place it in the mounting groove, and use a rubber rod to knock it in a circular motion along the bearing to knock the bearing into the mounting groove. The rubber rod knocks back and forth in a circular motion along the bearing, which mainly avoids the bearing from being knocked in too deep on one side, thereby causing the bearing to get stuck. In particular, when installing bearings on plastic parts of electronic equipment, the mounting groove has a certain elasticity, and it is even more necessary to ensure the uniformity of the knock-in depth.

[0004] However, during installation, one side of the bearing may be knocked in too deep, causing the bearing to tilt to a certain extent, and then the bearing may be stuck inside the installation groove, making installation inconvenient. Therefore, a bearing assembly tool is proposed to address the above problem. Utility Model Content
