The Beier variable-ratio gear or Beier variator is a mechanical drive offering a continuously variable gear ratio between input and output. The gear relies on the inter-meshing of a number of thin disks. By varying their separation, the effective radius of one disk varies, thus changing the overall gear ratio.
VEX V5 Robotics Competition (previously VEX EDR, VRC) is for middle and high school students. This is the largest league of the four. VEX Robotics teams have an opportunity to compete annually in the VEX V5 Robotics Competition (V5RC) [3] VEX IQ Robotics Competition is for elementary and middle school students. VEX IQ robotics teams have an ...
Transmission internals for a 2009 Volkswagen Golf. A transmission (also called a gearbox) is a mechanical device which uses a gear set—two or more gears working together—to change the speed, direction of rotation, or torque multiplication/reduction in a machine.
FIRST Tech Challenge (FTC), formerly known as FIRST Vex Challenge, is a robotics competition for students in grades 7–12 to compete head to head, by designing, building, and programming a robot to compete in an alliance format against other teams.
The involute gear profile, sometimes credited to Leonhard Euler, [1] was a fundamental advance in machine design, since unlike with other gear systems, the tooth profile of an involute gear depends only on the number of teeth on the gear, pressure angle, and pitch. That is, a gear's profile does not depend on the gear it mates with.
The Colts, now 4-6, will take on the New York Jets next week (1 p.m. ET, CBS). A win there will go a long way in turning their season around in an attempt to make the playoffs for the first time ...
A rack and pinion has roughly the same purpose as a worm gear with a rack replacing the gear, in that both convert torque to linear force. However the rack and pinion generally provides higher linear speed — since a full turn of the pinion displaces the rack by an amount equal to the pinion's pitch circle whereas a full rotation of the worm screw only displaces the rack by one tooth width.
Cycloidal drives can feature zero backlash and high torque capacity while being compact in size, unlike Involute gearboxes. They are useful in situations where low speed with high torque is required. Cycloidal drives may be designed with significantly higher contact areas for their size than any gear-based transmission such as epicyclic gearing ...
