TECHNICAL FIELD

[0001] The present application belongs to the field of flexible transmission protective demolition, and particularly relates to a flexible transmission protective demolition device. BACKGROUND

[0002] Since the flexible transmission is imported equipment from abroad, and the design service life of the flexible transmission is 30 years, a reasonable demolition method is not designed at the beginning, so once the flexible transmission is installed, it will be difficult to demolish. However, the flexible transmission must be demolished to replace the main shaft bearing of the star wheel at the head of the sintering machine, and the design service life of the domestic bearing is very short, so a method for safely and reliably demolishing the flexible transmission needs to be researched.

[0003] Since the installation precision of the flexible transmission is very high, and the cold installation gap is only 0.06 mm, in the demolition process, the absolute concentricity of the flexible transmission and the main shaft needs to be ensured to prevent the axial inclination of the flexible transmission from causing excessive resistance of the contact surface, resulting in the problem that the flexible transmission cannot be demolished, and in the demolition process, the flexible transmission gear is easily thrown out due to excessive pressure.

[0004] Therefore, we make improvements on this and propose a flexible transmission protective demolition device. SUMMARY
