    摘要： A compressor according to an exemplary embodiment of this disclosure, among other possible things includes, a rotor driven by a shaft and configured to compress air. A motor is drives the shaft. First and second journal bearings facilitate rotation of the shaft. The first journal bearing is located upstream from the motor, and the second journal bearing is located downstream from the motor. A thrust bearing also facilitates rotation of the shaft. The thrust bearing is downstream from the second journal bearing. A tie rod connects the shaft to a motor rotor shaft adjacent the first journal bearing. The tie rod includes an opening which is configured to communicate cooling air from the motor to the rotor. A method for cooling a compressor is also disclosed.

    摘要： A compressor includes a rotor driven by a shaft and configured to compress air, and a motor for driving the shaft. At least one bearing is utilized for facilitating rotation of the shaft. A motor cooling loop is configured to provide motor cooling air to the motor. A bearing cooling loop is configured to provide bearing cooling air to the at least one bearing. A bearing support is configured to support the least one bearing. The rotor includes an opening which is configured to communicate bearing cooling air into a cavity between the rotor and the bearing support. A method for cooling a compressor is also disclosed.

    摘要： A lockout tool for an air cycle machine includes a lockout tool body threaded section, a lockout tool body end section, and a lockout tool body conical tip. The lockout tool body threaded section is operable to engage a threaded port of the air cycle machine that is proximate to a shaft of the air cycle machine. The lockout tool body end section includes a rotation interface operable to receive a rotational force to control engagement of the lockout tool body threaded section with the threaded port. The lockout tool body conical tip is operable to engage the shaft of the air cycle machine to prevent rotation of the shaft.

    摘要： A method of repairing a compressor outlet housing includes the steps of obtaining a damaged compressor outlet housing having a radially outer volute, a radially inwardly extending finger extending to an axially extending ledge, a radially inwardly extending web extending radially inwardly from the ledge, and a radially inner bearing support defining a bore. The method identifies a damaged section within at least one of the bearing support, the web, and the ledge, and removes at least the bearing support and the web to leave a remaining part. The method then inserts an insert having at least a replacement bearing support and a replacement web into the remaining part after the removal step. The method then welds the insert to the remaining part to provide a repaired compressor housing. A method of replacing a compressor outlet housing and a replacement compressor outlet housing are also disclosed.
