Sealed rotator shaft for borescopic inspection

摘要

A rotator drive connection (90) for a gas turbine engine accessory box has a shaft (36) connected to be driven by a main shaft (28) in a gas turbine engine through a gear train (32,34). A first drive connection (52;66) allows selective drive of the shaft. A biased drive member (54;62) includes a second drive connection (74;134;144) selectively brought into contact with the first drive connection to allow rotation of the main shaft. The biased drive member biases the second drive connection out of contact with the first drive connection. A gas turbine engine accessory box and a method of borescopic inspection are also disclosed and claimed.
