Description

Technical Field

[0001] The invention belongs to the technical field of coupling installation, and in particular relates to a horizontal heating installation device for a coupling. Background Art

[0002] In the field of mechanical equipment manufacturing, couplings are widely used in equipment connections as a common connector. The coupling includes two butt flanges. In the process of connecting two shafts, each butt flange is fixedly connected to the corresponding shaft, and the two butt flanges are then fixedly connected by bolt assemblies, ultimately achieving mutual fixation of the two shafts.

[0003] First, the design size of mechanical equipment is getting bigger and bigger, and the size and weight of couplings are also getting bigger and bigger. During the installation and maintenance of equipment, the manual installation of couplings is becoming more and more difficult. In addition, if the coupling falls during the installation process, it is easy to cause damage to the operator and equipment. Secondly, in the actual installation process, the matching relationship between the docking flange and the shaft is an interference fit, that is, the docking flange is first heated, and the principle of thermal expansion and contraction is used to increase the aperture of the center hole of the docking flange, and then it is mounted on the shaft. After the temperature of the docking flange drops, the aperture of the center hole of the docking flange is restored, and the docking flange and the shaft achieve an interference fit. After the docking flange is heated, due to the high temperature of the docking flange, it is difficult to manually adjust the position of the docking flange so that the center hole of the docking flange is aligned with the shaft, resulting in difficulty in the installation of the coupling and low installation efficiency.

The outer ring of the active bearing 29 is fixedly connected to the active preload plate 21.

[0070] The driven longitudinal adjustable clamping structure includes a driven preload plate 20, a driven spring 19 and a driven vertical plate 18. The driven spring 19 is arranged between the driven preload plate 20 and the driven vertical plate 18 to apply a force to the driven preload plate 20 toward the active preload plate 21 to cooperate with the active preload plate 21 to clamp the coupling.

[0071] A guide groove is provided on the transverse platform, and the active preload plate 21 and the driven preload plate 20 are arranged in the guide groove 30, so that the active preload plate 21 and the driven preload plate 20 are stopped by the groove wall of the guide groove 30, thereby guiding the moving direction of the active preload plate 21 and the driven preload plate 20.
