Motor housing
An example housing of a cabin air compressor assembly includes a main body portion and a motor outlet duct extending radially from the main body portion. The motor outlet duct interfaces with the main body portion at an interface area. A ratio of a radius of the interface area to an inner diameter of the motor outlet duct is from 0.113 to 0.162.
1. A housing of a compressor assembly comprising:
a main body portion;
a motor outlet duct extending radially from the main body portion; and
a flange extending radially from the main body portion to the motor outlet duct, wherein the motor outlet duct interfaces with the main body portion at an interface area, wherein a ratio of a radius of the interface area to an inner diameter of the motor outlet duct is from 0.113 to 0.162.
2. The housing of claim 1 , wherein the main body portion is cylindrical.
3. The housing of claim 1 , wherein the motor outlet duct is angled backwards relative to a direction of flow though the main body portion.
4. The housing of claim 1 , wherein the inner radius is an inner radius at an end of the motor outlet duct furthest from the main body portion.
5. The housing of claim 1 , wherein the ratio is from 0.117 to 0.156.
6. The housing of claim 1 , wherein a ratio of a radius at a leading edge of the flange to a circumferential thickness of the flange is from 5.30 to 7.833.
7. The housing of claim 1 , wherein the flange interfaces with the motor outer duct and the main body portion at other interface areas having the radius.
8. The housing of claim 1 , further comprising at least one tie rod mounting flange providing an aperture configured to receive a tie rod, a centerpoint of the aperture is located a first distance from an end of the housing and a second distance from an a central axis of the housing, wherein a ratio of the first distance to the second distance is from 1.65 to 3.07.
9. The housing of claim 8 , further comprising a seal land provided within a compressor housing, an inwardly facing surface of the seal land spaced a first distance from a rotational axis of the compressor; and
a seal that is received within the seal land, an inwardly facing surface of the seal land spaced a second distance from the rotational axis of the compressor, wherein a ratio of the first distance to the second distance is from 1.139 to 1.145.
10. The housing of claim 1 , wherein the compressor assembly is a cabin air compressor assembly.
11. A housing of a compressor assembly comprising:
a housing; and
at least one tie rod mounting flange providing an aperture configured to receive a tie rod, a centerpoint of the aperture is located a first distance from an end of the housing and a second distance from a central axis of the housing, wherein a ratio of the first distance to the second distance is from 1.65 to 3.07.
12. The housing of claim 11 , wherein the end of the housing is an end of the housing opposite the tie rod mounting flange.
13. The housing of claim 11 , wherein the central axis is coaxial with a rotational axis of a motor held within the housing.
14. The housing of claim 11 , wherein the ratio is from 1.99 to 2.53.
15. The housing of claim 11 , wherein the at least one tie rod mounting flange comprises two flanges each providing an aperture, the apertures having a common centerpoint.
16. The housing of claim 11 , wherein the compressor assembly is a cabin air compressor assembly.
17. The housing of claim 11 , further comprising a flange extending radially from a main body portion of the housing to a motor outlet duct of the housing, wherein a ratio of a radius at a leading edge of the flange to a circumferential thickness of the flange is from 5.30 to 7.833.
18. A housing of a compressor assembly comprising:
a seal land provided within a compressor housing, an inwardly facing surface of the seal land spaced a first distance from a rotational axis of the compressor; and
a seal that is received within the seal land, an inwardly facing surface of the seal land spaced a second distance from the rotational axis of the compressor, wherein a ratio of the first distance to the second distance is from 1.139 to 1.145.
19. The housing of claim 18 , wherein the housing is configured to hold a motor of a cabin air compressor.
20. The housing of claim 18 , further comprising an outlet duct flange extending radially from a main body portion of the compressor housing to a motor outlet duct of the compressor housing, wherein a ratio of a radius at a leading edge of the flange to a circumferential thickness of the flange is from 5.30 to 7.833.
