Abstract
A gear wheel of a transmission, in particular of a transmission of a gas turbine engine is described, which is designed with a groove which extends in the circumferential direction on the outer periphery of a base body of the gear wheel and in which fibers running at least in the circumferential direction are arranged. The fibers surround the base body in the circumferential direction, wherein the fibers at least partially support the operating loads on the gear wheel only on a breakage of the base body.
Claims12
A gear wheel of a transmission, comprising:
- a base body;
- a groove which extends in a circumferential direction on an outer periphery of the base body and in which fibers running at least in a circumferential direction are arranged, surrounding the base body in the circumferential direction;
- wherein the fibers provide two operating modes:
- in a first mode, in a normal operation of the gear wheel, the fibers do not support operating loads of the gear wheel or contribute to the strength of the gear wheel;
- and
- in only a second mode, upon breakage of the gear wheel, the fibers at least partially support operating loads acting on the gear wheel.
