[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during their movement, and ensure their rotational accuracy. When installing bearings, most bearings are installed using a press-fit method, where an external shaft is directly pressed into the bearing using a press or other tools to achieve the connection between the shaft and the bearing.

[0003] Chinese patent application CN202321647017.7 discloses a bearing installation auxiliary device, including a base plate, a column, a base, and a hydraulic cylinder. The base and base plate are fixedly connected, and the column and base plate are also fixedly connected. L-shaped hooks and storage slots are provided on both sides of the column. A hydraulic cylinder is fixedly connected to the top of the column, and a steel plate is fixedly connected to the telescopic end of the hydraulic cylinder. The top of the base has four sliding grooves, each with a slidably connected support column. Each support column is rotatably connected to a screw, and each screw is threadedly connected to a fixing plate. Each fixing plate is fixedly connected to the top of the base, and a rotating handwheel is fixedly connected to the top of each screw. This device can be adjusted according to the size of the bearing; however, during bearing installation, it requires manual support and positioning of the rotating shaft, making it inconvenient to use.

[0004] Based on this, the present invention designs a bearing auxiliary installation device with uniform force to solve the above problems. Utility Model Content

[0010] Furthermore, the fixing components consist of four sets, which are evenly arranged circumferentially along the vertical center line at the top of the base.

[0011] Furthermore, the mounting bracket is equipped with an adjusting component on its side. The adjusting component includes a vertical sliding groove, a vertical sliding block, a vertical screw, a connecting rod, and a center plate.

[0015] Beneficial effects

[0016] 1. By setting up fixing parts, the bearing is fixed by adjusting the position of the fixing plate with an electric push rod. The fixing position can be adjusted according to the size of the bearing for easy use. By setting up a horizontal sliding groove, a horizontal sliding block, a horizontal screw, a clamping plate and a rotating rod, the horizontal screw can be rotated according to the size of the external rotating shaft. The horizontal screw and the horizontal sliding block are threaded together to drive the horizontal sliding block to move, thereby driving the two sets of clamping plates to move. With the assistance of the rotating rod, the rotating shaft is clamped and positioned. No manual support is required during installation, making it easy to use.

[0017] 2. By setting up a vertical sliding groove, vertical sliding block, vertical screw, connecting rod, center plate, and mounting plate, the vertical screw can be rotated according to the position where the bearing needs to be connected. The threaded engagement between the vertical screw and the vertical sliding block allows adjustment of the height of the fixing component, thereby adjusting the height of the bearing and the distance from the bottom of the bearing to the top of the base. This enables adjustment of the bearing installation position when connecting external shafts and external bearings. The through-type vertical sliding groove and vertical block facilitate the loading and unloading of the vertical sliding block, vertical screw, and connecting rod. Attached Figure Description
