Title:
SEAL STRUCTURE FOR INTER-BLADE SPACER
Document Type and Number:
Japanese Patent JP3684620
Kind Code:
B2
Abstract:
PURPOSE: To obtain a seal structure of an inter-blade spacer which can seal air leakage without peel-off of a seal member.
CONSTITUTION: A seal member installation groove 7 is formed on a surface of a spacer 3 arranged between base ends of a plurality of blades 2 installed on an outer periphery of a shaft, opposed to the blade 2. A seal rubber is adhered to an inner peripheral surface of the seal member installation groove 7 through an adhesion portion 11a. The rubber 11 is prepared by reducing recession 11c and an embedded rate of reinforcing fibers 11 so as to decrease transmission of a deformation force of a lip 11b which is pressurized with a blade surface to the adhesion portion. It is thus possible to secure sealability and prevent peel-off of the adhesion portion 11a from the spacer 3.
