[0002] Since the shaft sleeve heating method currently on the market is acetylene flame or a red-hot round steel rod to heat the inner hole of the shaft sleeve, and then install the pin, the seal of the shaft sleeve will be damaged or the service life will be greatly shortened due to poor temperature control.
At present, most of the shaft sleeves on the market are installed by electromagnetic induction heating, but this equipment is expensive and bulky, and it is not practical for the actual use of the factory. As a result, most factories use the knocking method to install the shaft sleeve pins. There is an interference fit between the bushing and the pin, and it is easy to damage the hard friction of the contact surface of the bushing and the pin by knocking, which seriously affects the operating life of the equipment

Embodiment
[0040] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0041] like figure 1 and 2 As shown, the sleeve heater in this embodiment includes a temperature sensor 5 , a container 4 , a heater 3 , an intelligent temperature controller 2 , a plug 1 and a bracket 6 .
[0042] A propagating medium is arranged inside the sealed container 4, and the outer diameter of the container 4 is 5 mm smaller than the inner diameter of the bushing to be heated. The heater 3 is arranged inside the container, and the temperature sensor 5 is used to measure the temperature of the transmission medium. The outside of the container is connected to the intelligent temperature controller 2, and the side wall of the container 4 is convexly provided with a filling port commun...

The invention relates to a shaft sleeve heater and a method for heating a shaft sleeve by using the same. Disclosed in the invention is a shaft sleeve heater; and thus a technical problem existing in the existing shaft sleeve heating method in the prior art can be solved. According to the technical scheme, the shaft sleeve heater comprises a sealed container, a heater, and a temperature. In addition, the invention also discloses a method for heating a shaft sleeve by using the same. The method includes: step one, calculating a temperature needing to be increased by heating; step two, adjusting a position; step three, installing a shaft sleeve heater; step four, sealing a gap; step five, injecting a propagation medium; step six, setting a temperature; step seven, starting heating; and step eighth, carrying out sleeving and installation of equipment. The shaft sleeve heater has advantages of good economic and practical effect and excellent simple and convenient performances and is not limited by space.
