Description

Technical Field

[0001] The utility model relates to the technical field of bearing processing, in particular to a bearing press-fitting device. Background Art

[0002] Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. When installing bearings internally, if the interference fit is large, the bearings can be placed on a flat surface and pressed into the bearings using a press.

[0003] The patent document with application number CN204657878U discloses a flywheel bearing press-fitting device. The utility model can automatically press the bearing into the bearing hole of the flywheel, has a high degree of automation and low labor intensity for workers. Since upper and lower pressure plates and cylindrical springs and other components are provided, the bearing can be pressed downward evenly, so that the bearing is evenly stressed in the circumferential direction, thereby effectively ensuring the concentricity of the bearing and the flywheel bearing hole, and preventing the bearing press-fitting plate from rigidly contacting the bearing, thereby avoiding damage to the bearing. The utility model has a simple structure, is easy to implement, and has good applicability.

[0004] In the supporting device of the above-mentioned comparative documents, the bearing is placed on a single plane. When the bearing is hydraulically pressed, the bearing is easily offset, which affects the installation efficiency of the bearing. Even when installing some large bearings, the internal parts may fly off, causing certain safety hazards. To address the above problems, we have launched a bearing press-fitting device.
