Description

Technical Field

[0001] The present invention relates to the technical field of bearing seats, and in particular to a suspended adaptive bearing seat. Background Art

[0002] A suspended bearing seat is a bearing seat that can accept comprehensive loads and has a special suspended support structure. It has the characteristics of compact structure, sensitive rotation, and easy installation and maintenance. The bearing must have a support point. The internal support point of the bearing is the shaft, and the external support is what is often called the bearing assembly seat. As one of the important categories of bearing seats, suspended bearing seats are widely used.

[0003] The bearing seat can refer to patent No. CN115585193B, which includes a mounting plate, and a first support seat and a second support seat are respectively provided on both sides of the top of the mounting plate, the first support seat is fixedly connected to the top of the mounting plate, and a slide groove is provided at the top of the mounting plate corresponding to the bottom of the second support seat, and the bottom of the second support seat is slidably installed in the slide groove, and the slide groove is vertically rotated away from the side of the first support seat and is penetrated by an adjusting screw; by providing a first clamping device and a second clamping device, when fixing the bearing, the first clamping device can cooperate with the second clamping device to complete the fixing operation of the bearing from both sides of the bearing, so that the middle part of the bearing is not blocked, and then cooperate with the heat dissipation device to effectively improve the heat dissipation effect of the bearing, and since the position of the second clamping device is adjustable, it can cooperate with the first clamping device to realize the locking operation of bearings with the same diameter but different widths.

[0004] Currently, suspended bearing seats generally adopt an integrated structural design. After installation and positioning, their spatial position is not adjustable. When there is a slight coaxial deviation between the bearing and the supported rotating component, the entire bearing must be disassembled and reinstalled. This not only consumes a lot of man-hours, but may also affect the assembly accuracy of the equipment due to repeated disassembly and assembly, significantly reducing maintenance efficiency and operational reliability. Summary of the Invention
