A turbomachine includes a housing and a rotatable shaft, where at least a portion of the rotatable shaft is located in the housing. The turbomachine also includes a magnetic thrust bearing that axially positions the rotatable shaft and a radial bearing that centers the rotatable shaft. The turbomachine includes a flexure including a first portion secured to the housing and a second portion axially moveable relative to the first portion. The second portion of the flexure is connected to the radial bearing, and the second portion moves axially to eliminate...

1. A turbomachine comprising: a housing;a rotatable shaft, wherein at least a portion of the rotatable shaft is located in the housing;a magnetic thurst bearing that axially positions the rotatable shaft;a radial bearing that centers the rotatable shaft; anda flexure including a first portion secured to the housing and a second portion axially moveable relative to the first portion, wherein the second portion contacts the radial bearing, and the second portion moves axially to eliminate thrust loads on the radial bearing and to allow the magnetic thrust bearing to carry axial loads, wherein the flexure is planar. 2. The turbomachine as recited in claim 1 wherein the radial bearing comprises at least one of a ball bearing, a foil bearing, and a journal bearing. 3. The turbomachine as recited in claim 1 including a bearing housing located radially outwardly of the radial bearing, and the bearing housing includes a portion of a working fluid passage to provide a working fluid to the radial bearing. 4. The turbomachine as recited in claim 3 wherein the housing includes another portion of the working fluid passage to provide the working fluid to the radial bearing. 5. The turbomachine as recited in claim 4 including a seal between the bearing housing and the housing. 6. The turbomachine as recited in claim 1 wherein the turbomachine is employed in a system that employs a working fluid, and the working fluid lubricates the radial bearing. 7. The turbomachine as recited in claim 1 wherein the flexure is formed of sheet metal. 8. The turbomachine as recited in claim 1 wherein the first portion of the flexure is an outer ring, the second portion of the flexure is an inner ring, and the flexure includes a plurality of flexible attachment features located therebetween that allow the inner ring to move relative to the outer ring, wherein each of the plurality of attachment features include an aperture to reduce axial stiffness. 9. The turbomachine as recited in claim 1 wherein the rotatable shaft is substantially vertical when the turbomachine is in use. 10. The turbomachine as recited in claim 1 wherein the turbomachine is a turbine in an organic rankine cycle. 11. The turbomachine as recited in claim 1 wherein the turbomachine is a compressor of a refrigeration system. 12. A turbomachine comprising: a housing;a rotatable shaft, wherein at least a portion of the rotatable shaft is located in the housing, and the rotatable shaft is substantially vertical when the turbomachine is in use;a magnetic thurst bearing that axially positions the rotatable shaft;a radial bearing that centers the rotatable shaft, wherein the turbomachine is employed in a system that employs a working fluid, and the working fluid lubricates the radial bearing; anda flexure including a first portion secured to the housing and a second portion axially moveable relative to the first portion, wherein the second portion contacts the radial bearing, and the second portion moves axially to eliminate thrust loads on the radial bearing and to allow the magnetic thrust bearing to carry axial loads, wherein the flexure is planar. 13. The turbomachine as recited in claim 12 including a bearing housing located radially outwardly of the radial bearing, and the bearing housing includes a portion of a working fluid passage and the housing includes another portion of the working fluid passage, wherein the working fluid passage provides the working fluid to the radial bearing. 14. The turbomachine as recited in claim 12 wherein the first portion of the flexure is an outer ring, the second portion of the flexure is an inner ring, and the flexure includes a plurality of flexible attachment features located therebetween that allow the inner ring to move relative to the outer ring, wherein each of the plurality of attachment features include an aperture to reduce axial stiffness. 15. The turbomachine as recited in claim 12 wherein the turbomachine is a turbine in an organic rankine cycle. 16. The turbomachine as recited in claim 12 wherein the turbomachine is a compressor of a refrigeration system. 17. The turbomachine as recited in claim 12 wherein an axial portion of an impeller is controlled to minimize a gap between the impeller and an impeller housing to maximize a compression efficiency or an expansion efficiency. 18. A method of reducing thrust loads on a radial bearing of a turbomachine, the method comprising the steps of: rotating a shaft located in a housing of a turbomachine;axially positioning the shaft with a magnetic thurst bearing;securing a first portion of a flexure to the housing, wherein the flexure is planar; andaxially moving a second portion of the flexure relative to the first portion of the flexure to axially translate radial bearing to eliminate axial loads on the radial bearing created by the magnetic thrust bearing and to allow the magnetic thrust bearing to carry axial loads. 19. The turbomachine as recited in claim 1 wherein the flexure has a constant thickness. 20. The turbomachine as recited in claim 1 wherein the flexure is made of carbon steel. 21. The turbomachine as recited in claim 1 wherein the flexure is laser cut.
