Helicopter Tail Shaft Rubber Bush Repair Method

Abstract

The invention relates to a method for repairing a helicopter tail shaft image rubber bush, which includes a rubber bush selection principle, a preparation method, a bonding method, and a cut treatment method, thereby ensuring the repair quality of the faulty rubber bush. When the rubber bush fails, the tail shaft repaired by the invention can continue to be put into use, so that the tail shaft of the helicopter can not be affected by the fault of the rubber bush in the whole life cycle, which reduces the use cost of the tail shaft of the helicopter and saves resource.

Description

Helicopter tail shaft rubber bush repair method Technical field [0001] The present invention relates to a repair method, especially a repair method for a helicopter tail shaft rubber bushing. Background technique Helicopter tail shaft is equipped with bearing, and bearing is contained on the tail shaft tube, and rubber is installed between bearing and tail shaft tube The bushing is used to protect the surface of the aluminum alloy tube from being worn and to eliminate part of the vibration during work. There are flanges at both ends of the tail shaft, When installing, install the bearing first, and then install the flange, and the outer diameter of the flange is larger than the inner diameter of the bearing. The tail shaft is not allowed to be dismantled within the life cycle Unload. When the rubber bush at the tail shaft bearing fails, it cannot be replaced normally, and the whole tail shaft can only be scrapped, so use The cost is high and the resources are wasted...
