Description

Technical Field

[0001] The present application relates to the technical field of annular heaters, and in particular to a heat-mounted annular heater for repairing mechanical equipment. Background Art

[0002] In the maintenance of mechanical equipment, the installation methods of sleeves and connectors mostly use interference fit and internal and external gear fit connection methods. In the past, when installing sleeves and connectors, open flames were often used to perform heat-installation operations on sleeves or connectors according to the size of the interference fit. When encountering connectors and sleeves with larger sizes and volumes, heat-installation ring heaters are required to ensure installation reliability.

[0003] A Chinese patent with the authorization number CN 213289302 U discloses a heat-mounted annular heater for mechanical equipment maintenance. When heating a shaft sleeve, the heat-mounted annular heater not only heats the outer surface thereof, but also moves the annular heater back and forth so that the shaft sleeve is heated more evenly. However, due to the different lengths of different shaft sleeves, in the above device, the back-and-forth moving distance of the annular heater remains unchanged. If the moving distance is greater than the length of the shaft sleeve, part of the distance will be wasted and time will be wasted. If the moving distance is less than the length of the shaft sleeve, incomplete heating of the shaft sleeve will result. Therefore, a heat-mounted annular heater for mechanical equipment maintenance is proposed to solve the above problems. Utility Model Content
