摘要:
A technique is provided for defining a self-forming sleeve between a male shaft and a female or hollow shaft. The self-forming sleeve prevents wear and fretting at the interface between the male shaft and the hollow shaft while permitting torque to be transmitted through the interface. The self-forming sleeve may be made of a curable liquid, such as an adhesive or sealing compound. The sleeve material is applied either to the hollow bore, to the male shaft, or to both immediately prior to an assembly step. Following curing or bonding of the self-forming sleeve, the sleeve will not drain, flow or otherwise be extruded from the interface between the male shaft and hollow bore, providing continued operation with a minimal degree of wear and fretting at the interface. The self-forming sleeve allows the mating male and hollow shafts to be disassembled, after extensive periods of operation, without excessive force and without significant damage to shafts and connected machinery.
