20140044480 | LATCH FOR SECURING A COMPUTE NODE IN A COMPONENT STORAGE RACK - A latch selectively secures a compute node enclosure into a chassis bay. The latch comprises a frame securable to a proximal end of the compute node enclosure. A handle is pivotally secured to the frame intermediate a proximal end of the handle and a distal end of the handle so that the handle can be pivoted between a closed position and an open position. A proximal end of a pawl is pivotally coupled at to the distal end of the handle, wherein the pawl includes a landing at a distal end of the pawl and a latch key intermediate proximal and distal ends of the pawl. Movement of the handle positions the pawl into engagement with a slot in chassis bay to assist installation and removal of the compute node enclosure. | 02-13-2014 |
20140044481 | LATCH FOR SECURING A COMPUTE NODE IN A COMPONENT STORAGE RACK - A latch comprises a frame securable to an enclosure, and a handle pivotally secured to the frame for pivoting between a closed position and an open position. The distal end of the handle has a drive pin extending therefrom. The latch also comprises a pawl having a latch key, a distal end secured to the frame, and a proximal end coupled to the drive pin. Closing the handle causes the drive pin to move the pawl toward a side of the chassis bay and deploy the latch key into engagement with a slot in the side of the chassis bay. Opening the handle causes the drive pin to move the pawl away from a side of the chassis bay and withdraw the latch key out of engagement with the slot in the side of the chassis bay. | 02-13-2014 |
20140044482 | LATCH FOR SECURING A COMPUTE NODE IN A COMPONENT STORAGE RACK - A latch comprises a frame securable to a device enclosure, and a handle slidably secured to the frame, wherein the handle can slide between an inward position and an outward position, and wherein the distal end of the handle has a drive pin. The latch further comprises a rigid pawl having a latch key, a distal end pivotally secured to the frame, and a slot that receives the drive pin. Inserting the handle causes the drive pin to move within the slot, push the pawl toward a side of a chassis bay, and deploy the latch key into engagement with a slot in the side of the chassis bay. Withdrawing the handle causes the drive pin to move within the slot, pull the pawl away from a side of the chassis bay, and withdraw the latch key out of engagement with the slot in the side of the chassis bay. | 02-13-2014 |

20140216172 | DEVICE AND METHOD FOR DETERMINING A BEARING PRELOAD - A device for determining a bearing preload of a rolling-element bearing includes an exciter configured to be attachable to a component of the rolling-element bearing and to excite the component of the rolling-element bearing and cause it to vibrate when the rolling-element bearing is not rotating, at least one vibration sensor configured to be attachable to the component or to a further component of the rolling-element bearing and to record (capture) a mechanical reaction, in response to the excitation, of the component or the further component of the rolling-element bearing, and an evaluating circuit configured to receive the sensor signal and provide an evaluation signal based on the sensor signal, the evaluation signal including information about the bearing preload. An associated method and computer program are also disclosed. | 08-07-2014 |
20140363113 | ROLLING-ELEMENT BEARING - A rolling-element bearing includes a first rolling-element bearing ring configured to be mechanically connectable to a stationary component, a second rolling-element bearing ring configured to be mechanically connectable to a rotating component and at least one porous body disposed between the first rolling-element bearing ring and the second rolling-element bearing ring and configured to hold a lubricant. The at least one porous body is mechanically coupled to the second rolling-element bearing ring and configured such that during rotation of the second rolling-element bearing ring the at least one porous body substantially rotates with the second rolling-element bearing ring, and, due to this rotation, releases an amount of the lubricant. The at least one porous body is further configured to absorb at least a portion of the released amount lubricant when the second rolling-element bearing ring is stationary. | 12-11-2014 |
20140363114 | ROLLING ELEMENT BEARING CAGE SECTION, ROLLING-ELEMENT BEARING CAGE, AND ROLLING-ELEMENT BEARING - A rolling-element bearing cage section for a rolling-element bearing is configured to guide at least one rolling element between a first and a second rolling-element bearing ring of the rolling-element bearing. The rolling-element bearing cage section is configured to partially or completely receive the at least one rolling element prior to installation in the rolling-element bearing. The rolling-element bearing cage section includes a porous material adapted to absorb a lubricant and release the lubricant as a result of a centrifugal force acting on the lubricant during rotation of the rolling-element bearing cage section, thus allowing a liquid lubricant to be used in a rolling-element bearing without the need for complex seals. | 12-11-2014 |
20150052758 | METHOD FOR SETTING THE PRELOAD IN A BEARING ASSEMBLY - A method for adjusting an axial preload in a bearing assembly that has two rolling-element bearings that are axially pressable against each other, each of the two rolling-element bearings including at least one bearing outer ring and at least one bearing inner ring and at least one row of rolling elements disposed between the at least one bearing outer ring and at least one bearing inner ring. The method includes a) driving the bearing assembly by rotating one of the bearing outer ring and the bearing inner ring while holding other bearing ring fixed and measuring the rotational speed of the circulation of the rolling elements about the bearing assembly axis or of a bearing cage about the stationary bearing ring, and b) changing the axial preload in the bearing assembly until a desired rotational speed has been obtained. | 02-26-2015 |
