Description

Technical Field

[0001] The utility model belongs to the technical field of roller bearing press-fitting, in particular to a polyurethane roller bearing press-fitting machine. Background Art

[0002] Rollers are important parts of belt conveyors. There are many types and large quantities of them, including polyurethane rollers, which account for 35% of the total cost of a belt conveyor and produce more than 70% of the resistance. Therefore, the quality of rollers is particularly important. The function of rollers is to support the weight of the conveyor belt and materials. The operation of rollers must be flexible and reliable. It can be seen that the role of their bearings is particularly important. Reducing the friction between the conveyor belt and the rollers plays a key role in the life of the conveyor belt, which accounts for more than 25% of the total cost of the conveyor. The friction between the conveyor belt and the roller drives the roller drum, bearing seat, bearing outer ring and sealing ring to rotate, and the conveyor belt and the roller realize the transmission of logistics together. Here, the inner ring of the bearing needs to have an interference fit with the roller shaft to ensure that the outer ring of the bearing and the roller drum, bearing seat and sealing ring can rotate relative to the roller shaft with low resistance. Generally, rollers are mass-produced, and manual press-fitting of bearings is inefficient and labor-intensive. Especially for longer rollers, since the roller shaft is also longer, manual press-fitting of bearings is more complicated and the press-fitting effect is not good. A press-fitting device that can replace manual work is needed to press the bearings on both ends of the roller shaft easily, efficiently and with high quality.

[0003] For example, the Chinese patent with publication number CN206140088U discloses a polyurethane roller bearing press machine, including a frame, a hydraulic cylinder installed on the top of the frame, a press platform, and a control console arranged on the side of the frame, characterized in that: the frame is evenly provided with support rods in the vertical direction, the press platform is movably placed on the support rods, a movable press block for positioning the roller shaft is arranged on the press platform, a top block is arranged at the end of the hydraulic rod in the hydraulic cylinder, and the top block corresponds to the press block, a circular roller groove corresponding to the top block is arranged on the press block, and a raised circular ring is arranged at the bottom of the circular roller groove

[0004] Shaped top ring.

[0005] The patent has the following problems:

[0006] In the prior art documents, it is not convenient to position and press the roller bearings during use. When the roller bearings are pressed, misalignment may occur, resulting in press-fitting errors, thereby reducing the accuracy of the positioning and press-fitting of the roller bearings. In addition, in the prior art documents, it is not convenient to protect the roller bearings during press-fitting. When the roller bearings are pressed, the roller bearings may accidentally fly out, thereby reducing the safety of the roller bearing press-fitting. In view of this, we propose a polyurethane roller bearing press-fitting machine. Utility Model Content
