The installment and dismount of more interference fitting for the drum shear's gear by heating
In the installation process of heavy parts,in order to make the assembled parts output high torque and bear huge impact load,interference fit is applied more frequently.Interference installation is easier,but it is usually difficult to dismount interference parts.Due to one of the synchronous gear of 3 500 mm drum shear was not assembled into the right place,it's necessary to adjust the position of the gear to the correct place.The feasibility of induction heating is verified by theoretical calculation.Finally,through this method,the shifting of the interference parts is realized,the tooth surface hardness is protected,and the interference fit surface is not damaged.The reliability and safety of the method of removing interference parts by medium-frequency induction heating are proved by practical application.The synchronous gear of 2 250 mm tandem-mill drum flying shear is also successfully dismounted by this method.
