Abstract
An exemplary shield includes an attachment mechanism disposed on an outer surface to attach the shield to a joint of a boreless compressor wheel and a passage extending from a proximate end of the shield to a distal end of the shield. An exemplary method includes inserting a shield at least partially in a joint of a boreless compressor wheel and treating, at least partially, an end surface of the joint to thereby reduce fatigue of the boreless compressor wheel. Other exemplary joints, compressor wheels, shields, etc., are also disclosed.
Claims23
A shield comprising:
- an attachment mechanism disposed on an outer surface to attach the shield to a joint of a boreless compressor wheel wherein the attachment mechanism allows for removal of the shield prior to fitting an operational shaft to the boreless compressor wheel;
- and
- a passage extending from a proximate end of the shield to a distal end of the shield.
An assembly comprising:
- a boreless compressor wheel that includes a joint;
- and
- a shield that comprises an attachment mechanism disposed on an outer surface to attach the shield to the joint and a passage extending from a proximate end of the shield to a distal end of the shield wherein the attachment mechanism allows for removal of the shield prior to fitting an operational shaft to the boreless compressor wheel.
A boreless compressor wheel comprising a joint that includes an end surface at least partially treated by a cold working, and a shaft inserted at least partially in the joint, the shaft contacting an untreated pilot surface of the joint.
A method comprising:
- inserting a shield at least partially in a joint of a boreless compressor wheel;
- treating, at least partially, an end surface of the joint to thereby reduce fatigue of the boreless compressor wheel;
- and
- removing the shield from the joint.
A shield comprising:
- an attachment mechanism disposed on an outer surface to attach the shield to a joint of a boreless compressor wheel wherein the attachment mechanism comprises threads;
- and
- a passage extending from a proximate end of the shield to a distal end of the shield.
A shield comprising:
- a resin;
- an attachment mechanism disposed on an outer surface to attach the shield to a joint of a boreless compressor wheel;
- and
- a passage extending from a proximate end of the shield to a distal end of the shield.
A shield comprising:
- an attachment mechanism disposed on an outer surface to attach the shield to a joint of a boreless compressor wheel;
- a passage extending from a proximate end of the shield to a distal end of the shield;
- and
- a base portion that includes an attachment mechanism to attach the shield to a filling of a tube associated with a cold working process.
