Description

Technical Field

[0001] The utility model relates to the technical field of nuclear power, in particular to a heating device which is convenient for disassembling and assembling a coupling. Background Art

[0002] The coupling is used to connect the driving shaft and the driven shaft to transmit torque. The coupling and the shaft usually adopt transition fit, and some also adopt interference fit. To ensure the safety of parts, the on-site disassembly process is often carried out by torch heating: the surface of the coupling is heated with a torch to make it expand rapidly due to heat, and a large enough radial clearance is created with the shaft before disassembly.

[0003] The torch baking heating process is inconvenient to heat, which can easily cause strain on the coupling and the shaft. When the strain is serious, the coupling and the shaft are unusable and scrapped. In addition, the torch heating efficiency is low, which greatly prolongs the working time, and the torch needs to be held manually. If the flame falls, it can easily cause other safety accidents.

For example, after heating, the heating temperature can reach above 400°C, and the temperature rise rate is not less than 5°C per second.
