A cycloidal drive or cycloidal speed reducer is a mechanism for reducing the speed of an input shaft by a certain ratio. Cycloidal speed reducers are capable of relatively high ratios in compact sizes with very low backlash. [1] The input shaft drives an eccentric bearing that in turn drives the cycloidal disc in an eccentric, cycloidal motion ...
Through work I recently attended a tour of a Sumitomo assembly facility in Surrey, BC, Canada, and recalled seeing the discussion on this page. I asked the Sumitomo rep if cycloidal drives are back-drivable. He conferred with the shop supervisor, and they agreed that their cycloidal drives are back-drivable if the reduction ratio is less than 60.
A cyclorotor, cycloidal rotor, cycloidal propeller or cyclogiro, is a fluid propulsion device that converts shaft power into the acceleration of a fluid using a rotating axis perpendicular to the direction of fluid motion. It uses several blades with a spanwise axis parallel to the axis of rotation and perpendicular to the direction of fluid ...
The basic concept of strain wave gearing (SWG) was introduced by C.W. Musser in a 1957 patent [5] [6] while he was an advisor at United Shoe Machinery Corp (USM). It was first used successfully in 1960 by USM Co. and later by Hasegawa Gear Works under license of USM.
In the 2000s, the American agency sought to improve the dissemination of NCAP ratings and as a result of the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA–LU). It did so by issuing a Final Rule requiring manufacturers to place NCAP star ratings on the Monroney sticker (automobile price sticker ...
RF Drive testing is a method of measuring and assessing the coverage, capacity and Quality of Service (QoS) of a mobile radio network.. The technique consists of using a motor vehicle containing mobile radio network air interface measurement equipment that can detect and record a wide variety of the physical and virtual parameters of mobile cellular service in a given geographical area.
The Transportation Research Center (TRC) is North America's largest multi-user automotive proving ground. It is operated by TRC Inc. The center occupies 4,500 acres in East Liberty, Ohio, about 40 miles northwest of Columbus, Ohio. These 4,500 acres are split between the main TRC property and a rural road/ATV course located approximately 2.5 ...
