A shroud 10 is carried by a housing 14 of a hydraulic machine 12. The shroud 10 at least partially encloses a rotating fan 74 disposed on a rotating shaft 72 that extends from the housing. The shroud 10 includes a mounting portion 22 having a peripheral mounting wall 50 that encircles the housing 14 with an interference fit and that includes tapered slots 60 for receiving tapered cooling fins 62 of the housing 14. The shroud 10 also includes a shroud portion 20 formed of integral one piece construction with the mounting portion. The shroud portion 20 includes a peripheral shroud wall 30 and a perforated shroud cover wall 38. The shroud portion 20 is arranged in cantilever relation to the mounting portion 22. A stop member 40, 44 engages a rotating end of the shaft 72 to limit deflection of the cantilevered shroud member toward the fan 74.

1. A shroud for at least partially enclosing a rotating component of a machine having a housing from which the rotating component extends, the shroud comprising: a mounting portion, the mounting portion including a mounting surface for being secured to the housing; anda shroud portion, the shroud portion including an enclosing portion for at least partially enclosing the rotating component, and a stop member carried by the enclosing portion for engaging a central end face of the rotating component to limit deflection of the stop member and the shroud portion in a direction toward the rotating component;wherein the shroud portion and stop member are movable between an at rest position in which the stop member is spaced from the rotating component and a deflected position in which the stop member engages the rotating component to limit deflection movement of the shroud portion away from its at rest position and toward the rotating component. 2. A shroud as set forth in claim 1, wherein the mounting portion is stationary and the shroud portion is movable between the at rest position and the deflected position relative to the mounting portion. 3. A shroud as set forth in claim 2, wherein the mounting portion includes a mounting wall portion for being secured to the housing. 4. A shroud as set forth in claim 3, wherein the mounting wall portion includes a plurality of tapered slots for engaging tapered fins on the housing. 5. A shroud as set forth in claim 4, wherein the mounting wall portion includes at least one compressible ridge for engaging the housing and biasing the tapered slots toward the tapered fins. 6. A shroud as set forth in claim 3, wherein the mounting wall portion is a continuous uninterrupted wall. 7. A shroud as set forth in claim 1, wherein the mounting portion and the shroud portion are of integral one piece construction. 8. A shroud as set forth in claim 7, wherein the shroud portion is disposed in cantilevered relationship to the mounting portion. 9. A shroud as set forth in claim 8, wherein the shroud portion includes a shroud peripheral wall for extending around the rotating member and a perforated cover all attached to the peripheral wall for covering a rotating end of the rotating member, and a portion of the mounting wall portion forms a portion of the shroud peripheral wall portion. 10. A shroud as set forth in claim 9, wherein the stop member is carried by the perforated cover wall. 11. A shroud as set forth in claim 1, wherein the shroud is in combination with a housing and rotating member extending from the housing. 12. A shroud as set forth in claim 11, wherein the rotating component carries an air flow fan, the shroud peripheral wall extends around the fan, the perforated cover wall extends over the fan, the stop is axially aligned with the rotating end of the rotating component, and the stop and the rotating end are disposed in coaxial nested relationship. 13. A shroud as set forth in claim 12, wherein the housing is a portion of a hydraulic machine. 14. A shroud for at least partially enclosing a rotating component of a machine having a housing from which the rotating component extends, the shroud comprising: a mounting portion, the mounting portion including a stationary mounting surface for being secured to the housing; anda movable shroud portion, the movable shroud portion being affixed in cantilever relationship to the mounting portion, the shroud portion including an enclosing portion for at least partially enclosing the rotating component, and a stop member carried by the enclosing portion for engaging another portion of the machine to limit deflection of the stop member and the shroud portion; andwherein the mounting portion and said shroud portion are of integral construction. 15. A shroud as set forth in claim 14, wherein the other portion of the machine is an end face of the rotating component. 16. A shroud as set forth in claim 15, in combination with the machine, wherein the stop member and the rotating component are coaxially disposed. 17. A shroud as set forth in claim 14, wherein the shroud mounting surface includes one side of a continuous shroud mounting wall encircling a portion of the housing, the shroud portion includes a shroud peripheral wall for extending around the rotating member and a perforated cover wall attached to the peripheral wall for covering a rotating end of the rotating member, a portion of the mounting wall portion forms a portion of the shroud peripheral wall portion, the stop member is carried by the perforated cover wall, the rotating component carries an air flow fan, the shroud peripheral wall extends around the fan, the perforated cover wall extends over the fan, the stop is axially aligned with the rotating end of the rotating component, and the stop includes a bore into which an end of the rotating member project.
