Nabtesco (ナブテスコ株式会社, Nabutesuko Kabushiki-gaisha) is a Japanese engineering company that specializes in gearboxes, rotors, motors and robotics. History [ edit ]
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 cycloid (as used for the flank shape of a cycloidal gear) is constructed by rolling a rolling circle on a base circle. If the diameter of this rolling circle is chosen to be infinitely large, a straight line is obtained. The resulting cycloid is then called an involute and the gear is called an involute gear. In this respect involute gears ...
Elon Musk and Vivek Ramaswamy—two billionaire entrepreneurs and new Trump administration advisors—are making bold promises. Namely: This week, the duo told Congress that through their advisory ...
A new study found less than .1% of transgender and gender-diverse teens are prescribed puberty blockers or gender-affirming hormones.
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.
