Patent number: 11644084Abstract: A sensor is used in measuring the torque applied to a slew drive. The slew drive includes a worm gear and a worm wheel and the sensor is coupled with a securing device that is used to secure the worm gear to the slew drive housing. The sensor generates a signal which is indicative of the torque on the worm wheel. The worm gear is secured to the slew drive housing by a first bearing and a second bearing. Two end plates and eight bolts are also used to further secure the worm gear and the bearings to the slew drive housing. By tightening the bolts, a compressive force is applied on the worm gear through the bearings. The applied torque on the worm wheel causes an axial force on the worm gear. The axial force is transmitted through the worm gear, the bearings, the end plates, and the bolts. One or more sensors can be embedded in one or more of the end plates or the bolts to measure the strain, in the end plates or the bolts, due to the axial force.Type: GrantFiled: September 27, 2019Date of Patent: May 9, 2023Assignee: KINEMATICS, LLCInventor: Adam P. Plesniak

Publication number: 20220082164Abstract: Slew drive systems for rotational and axial load bearing, e.g., in applications including satellite-based telecommunications systems, are disclosed herein. In some cases, slew drive systems disclosed herein can improve efficiency, accuracy, and/or reliability of telecommunication systems while reducing the cost and complexity of manufacture. For example, a slew drive system can comprise a threaded plug and a retaining ring in addition to a worm gear, a plurality of tapered roller bearings, and a worm wheel, allowing a significant reduction in material and labor costs of slew drive manufacture, which can be critical in the manufacture of expensive telecommunications system actuator assemblies.Type: ApplicationFiled: August 13, 2021Publication date: March 17, 2022Inventors: Adam P. Plesniak, Kenneth D. Miller, Kyle Zech, Mark Henderson

Publication number: 20200386294Abstract: A rack and pinion damper provides controllable rotary motion of a pinion by actuating a rack inside a fluid disposed within a housing. The rack includes one or two cylindrical heads which further include flow-control mechanisms. Two plugs maybe threaded into the ends of the rack sections of the housing to limit a maximum clockwise rotation and a maximum counterclockwise rotation of the pinion. The pinion maybe coupled with an external unit, such as a torque tube, to control its rotational motion.Type: ApplicationFiled: April 29, 2020Publication date: December 10, 2020Applicant: Kinematics, LLCInventor: Adam P.

Patent number: 10655716Abstract: A slew drive comprises a worm gear which is integrated with a reducer assembly. One end of the worm gear operates as a carrier which engages a plurality of planetary gears which are part of the reducer assembly. The carrier may be a separate component that is coupled with the worm gear. Alternatively, one end of the worm gear can be machined to operate as the carrier. The carrier engages a plurality of planetary gears via a plurality of holes.Type: GrantFiled: August 23, 2018Date of Patent: May 19, 2020Assignee: KINEMATICS, LLCInventors: Kenneth D. Miller, Adam P.

Publication number: 20190101206Abstract: A slew drive comprises a slew drive housing which includes a first distal housing section and a second distal housing section. The first distal housing section includes a threaded section, operative to receive a threaded plug and the second distal housing section includes a groove operative to receive a retaining ring. A worm gear is secured to the slew drive housing by a first tapered roller bearing and a second tapered roller bearing. The worm gear comprises a central threaded section, a first distal shaft section having a first shoulder, and a second distal shaft section having a second shoulder. The central threaded section engages the teeth of a worm wheel, the first tapered roller bearing is seated on the first distal shaft section, abutting the first shoulder and the plug, and the second tapered roller bearing is seated on the second distal shaft section, abutting the second shoulder and the retaining ring.Type: ApplicationFiled: September 17, 2018Publication date: April 4, 2019Applicant: Kinematics, LLCInventors: Adam P.
