Publication number: 20230075831Abstract: Devices to couple a drive hub to a driven hub. The devices may comprise a drive hub contoured end connected to a first end of a spacer column and to a spacer drive hub flange. A portion of the drive hub contoured end may project radially out from the spacer column with a first contoured side and a first flat side and may allow movement in an axial direction and transmit torque and an axial load. The devices may comprise a driven hub contoured end connected to a second end of the spacer column and to a spacer driven hub flange. A portion of the driven hub contoured end may project radially out from the spacer column with a second contoured side and a second flat side and may allow movement in an axial direction and transmit torque and an axial load.Type: ApplicationFiled: October 5, 2022Publication date: March 9, 2023Inventors: Daniel Stephen Miller, Paul Walter Behnke

Patent number: 11428270Abstract: Rotating equipment includes driver equipment, driven equipment and a rotating shaft coupling. The driver equipment includes a driver support connected to a stationary driver shaft, and also includes a driver arranged on the driver support with a driving shaft to rotate and provide a rotational torque. The driven equipment includes a driven unit support connected to a stationary driven unit shaft, and also includes a driven unit arranged on the driven unit support with a driven shaft to respond to the rotational torque and rotate. The rotating shaft coupling couples the driving shaft to the driven shaft and applies the rotational torque from the driving shaft to the driven shaft. The stationary driver shaft couples to the stationary driven unit shaft to provide a static torque load to counteract the rotational torque applied from the driving shaft to the driven shaft during operation.Type: GrantFiled: August 17, 2018Date of Patent: August 30, 2022Assignee: ITT MANUFACTURING ENTERPRISES LLCInventors: Paul Walter Behnke, Daniel Stephen Miller, Abhi Nutankumar Gandhi

Patent number: 11136998Abstract: A vertical pump features a shaft having an end with an impeller arranged thereon and rotates about an axis; a stationary bushing having an axial bushing surface, a radial bushing surface, and a central bushing bore; and a thrust balance drum that includes a central balancing drum bore to receive the shaft, that couples to the shaft so as to rotate about the axis, that includes an axial balance drum surface and a radial balance drum surface, and that is arranged in the central bushing bore of the stationary bushing with the axial balance drum surface positioned with respect to the axial bushing surface to define an axial clearance, and with the radial balance drum surface positioned with respect to the radial bushing surface to define a radial clearance. In operation, the thrust balance drum balances thrust loads produced by the impeller.Type: GrantFiled: January 31, 2019Date of Patent: October 5, 2021Assignee: ITT MANUFACTURING ENTERPRISES, LLCInventors: Paul Walter Behnke, Daniel Stephen Miller, Abhi Nutankumar Gandhi

Patent number: 11131315Abstract: Technologies are described for devices and methods for adjusting a position of impellers within a bowl assembly. The devices may comprise an adjuster at the second end of a spacer coupling. The adjuster may include an adjuster sleeve. The adjuster sleeve may be a cylindrical sleeve. The adjuster sleeve may be threaded on an internal side. The adjuster sleeve may be spaced from the driven hub so that the adjuster sleeve can rotate around a driven shaft. The adjuster sleeve may threadedly mate and engage with an externally threaded first end of the driven shaft when the adjuster sleeve is rotated. The rotation of the adjuster sleeve may adjust a position of the driven shaft with respect to the driven hub and may thereby adjust a position of an impeller attached to a second end of the driven shaft with respect to a stationary bowl.Type: GrantFiled: November 14, 2018Date of Patent: September 28, 2021Assignee: ITT MANUFACTURING ENTIRPISES LLCInventors: Daniel Stephen Miller, Paul Walter Behnke
