20120219444 | INPUT SHAFT LUBRICATION FOR GEAR PUMP - A shaft assembly includes a gear with a gear bore having a splined bore section adjacent to an oil dam. A shaft includes a first splined end section and a second splined end section, the first splined end section engageable with the splined inner diameter, the shaft having a bore with a bore diameter greater than a diameter of the oil dam, a first set of radial apertures axially inboard of the first splined end section in communication with the shaft inner bore and a second set of radial apertures axially inboard of the second splined end section in communication with the shaft inner bore that altogether provide lubrication of the splined end sections. | 08-30-2012 |
20120219445 | SEAL RETAINING SLEEVE FOR GEAR PUMP - A shaft assembly includes a shaft with a first radial shoulder and a second radial shoulder along a shaft axis. A seal retaining sleeve is defined around the shaft axis to position a shaft seal. A retainer plate at least partially between the first radial shoulder and the second radial shoulder is adjacent to the seal retaining sleeve to position and provide access to the seal retaining sleeve and shaft seal. | 08-30-2012 |
20120219446 | INPUT SHAFT ASSEMBLY FOR GEAR PUMP - A shaft assembly includes a shaft with a first radial shoulder and a second radial shoulder. A retainer plate is located at least partially between the first radial shoulder and the second radial shoulder to avoid damage when an impact load is applied to the shaft. A spring assembly biases the shaft out of contact with the retainer plate during operation. | 08-30-2012 |
20120219447 | COUPLING SHAFT FOR GEAR PUMP - A coupling shaft assembly includes a coupling shaft with a first radial shoulder and a second radial shoulder, the first radial shoulder and the second radial shoulder each include at least one slot to provide a lubricant flow path. | 08-30-2012 |
20120219449 | BEARING FACE GEOMETRY FOR GEAR PUMP - A bearing includes a bridge land geometry having a finger cut that defines a width ISW, a center of the width ISW displaced from a shaft axis a radial distance ISR, a ratio of ISW/ISR between 0.074-0.293, to reduce cavitation and pressure ripple. | 08-30-2012 |
20130017113 | CONTAINED SHAFT SPRING LOADAANM Walgren; Timothy P.AACI ByronAAST ILAACO USAAGP Walgren; Timothy P. Byron IL USAANM Heitz; Steven A.AACI RockfordAAST ILAACO USAAGP Heitz; Steven A. Rockford IL US - An input shaft assembly is movable along an axis to absorb external impact loads. A biasing member exerts an axial load in a direction counter to potential impact loads. A stop is provided to control the application of biasing loads to control application of such axial load. | 01-17-2013 |
20130180403 | DEAERATING ASSEMBLY - An example method of deaerating a mixture of fluid and air includes communicating a mixture of fluid and air directly against a wall of a reservoir to separate the fluid from the air. The method reuses the fluid held within the reservoir after the separating. | 07-18-2013 |
20130184113 | OVERSHAFT FLUID TRANSFER COUPLING AND MOUNTING ARRANGEMENT - In one example embodiment, a fluid transfer coupling arrangement includes a hollow shaft that is arranged in a housing and rotatable about an axis. The hollow shaft is provided by a wall having radially spaced interior and exterior surfaces. A first passage extends through the wall and is configured to communicate fluid between the interior and exterior surfaces. A fluid coupling is located mid-shaft, sealed about the exterior surface, and aligns to the first passage. The fluid coupling provides a second passage that is in fluid communication with the first passage. The fluid coupling includes a locating feature configured to permit radial movement of the fluid coupling relative to the housing and allowing the fluid coupling to track subtle shaft movements. | 07-18-2013 |
20130334360 | CLUTCH WITH PRESSURE SUSTAINING SYSTEM - An assembly includes an output shaft, an input shaft with an internal reservoir, and a clutch. The clutch is adapted to selectively engage and couple the input shaft to the output shaft. The clutch has a pressure chamber that communicates with the reservoir of the input shaft. The reservoir has a sufficient volume to provide the pressure chamber with a fluid pressure adequate to maintain engagement of the clutch during an interruption of a fluid supply to the input shaft and clutch. | 12-19-2013 |
20140348685 | COUPLING SHAFT FOR GEAR PUMP - A shaft assembly includes a shaft with a first radial shoulder and a second radial shoulder. The first radial shoulder and the second radial shoulder each include at least one slot. An axial separation between the first radial shoulder and the second radial shoulder defines an axial distance SA along an axis of rotation. The at least one slot defines a lowermost radial dimension SR from the axis of rotation. A ratio of SR/SA is 0.25-0.77. | 11-27-2014 |
