Description

Technical Field

[0001] The utility model relates to the technical field of bearing production, in particular to a preheating type bearing and bearing seat assembly device. Background Art

[0002] The bearing seat is a large and extra-large bearing seat with a special structure that can accept comprehensive loads. It has the characteristics of compact structure, flexible rotation, easy installation and maintenance. Where there is a bearing, there must be a support point. The inner support point of the bearing is the shaft, and the outer support is the bearing seat.

[0003] Bearings are high-precision, high-performance parts. Improper assembly methods will affect their performance and life. When assembling the bearing to the bearing seat, first preheat the bearing. Heat the bearing to 120°C and keep it for 30 minutes to improve installation efficiency. Then, heat half of the heated inner ring on the shaft and use an adjusting sleeve to squeeze and adjust it so that the inner ring of the bearing is close to the end face of the pad to ensure a close fit between the inner ring of the bearing and the shaft. Finally, heat the other half of the inner ring and heat it on the shaft. Use the adjusting sleeve to squeeze and adjust it again so that the outer end of the inner ring of the bearing is flush with the surface of the outer ring of the bearing and ensure that the bearing can rotate flexibly.

[0004] When assembling the bearing seat, the installation force required to install the bearing increases rapidly as the bearing size increases. Due to the installation force requirements, larger bearings are not easy to push onto the shaft or into the bearing seat. Therefore, the bearing or the bearing seat or the annular workpiece needs to be heated before installation to avoid damage during the installation process. Therefore, the bearing is usually preheated when assembling the bearing and the bearing seat. In the prior art, the bearing is usually placed in the bearing seat by a person wearing heat-insulating gloves, tightly fitting with the shaft, and then the bearing seat is locked to complete the assembly. However, in the prior art, during the assembly of the bearing seat, the temperature of the bearing is high after the bearing is preheated. Although heat-insulating gloves are worn when the preheated bearing is taken manually, in the event of some unexpected situations, the bearing may still burn the worker's arm, and the efficiency of manually taking the preheated bearing is low, which affects the speed of the bearing seat assembly.

When working, the heating plate is started first, the preheating mechanism preheats the bearing, and then the assembly mechanism is started to push the bearing into the assembly mechanism and assemble it together with the bearing seat. During the process, the preheating mechanism can protect the safety of workers and prevent workers from being scalded. In addition, the assembly mechanism and the preheating mechanism cooperate to push the preheated bearing directly onto the bearing seat for assembly, which is more efficient.

[0044] Among them, the preheating mechanism includes a preheating cylinder 5 and a clamping assembly 6. The preheating cylinder 5 is fixedly connected to the bottom end of the support platform 1, and the two electric heating plates 3 are fixedly connected to the inner wall of the preheating cylinder 5.
