A crossed helical gear is a gear that operate on non-intersecting, non-parallel axes. The term crossed helical gears has superseded the term spiral gears. There is theoretically point contact between the teeth at any instant. They have teeth of the same or different helix angles, of the same or opposite hand.

Clod Buster. The Tamiya Clod Buster is a 1/10-scale radio controlled monster truck released September 21, 1987 by the Tamiya Corporation. With its four-wheel drive, four-wheel steering, twin Mabuchi RS-540 motors and 165 mm tires it quickly became one of Tamiya's most popular radio controlled model kits. The Clod Buster and its related models ...
An RC flyer demonstrating knife edge flying. A radio-controlled aircraft (often called RC aircraft or RC plane) is a small flying machine that is radio controlled by an operator on the ground using a hand-held radio transmitter. The transmitter continuously communicates with a receiver within the craft that sends signals to servomechanisms ...
Worm-and-gear sets are a simple and compact way to achieve a high torque, low speed gear ratio. For example, helical gears are normally limited to gear ratios of less than 10:1 while worm-and-gear sets vary from 10:1 to 500:1. [45] A disadvantage is the potential for considerable sliding action, leading to low efficiency. [46]
L-series (HSD) The L-series (HSD) are Hybrid Synergy Drive transmissions used in Toyota and Lexus hybrids for RWD-based platforms. [ 4] Models: L310 Crown Hybrid 3.5L (2018-2022), Lexus LC500h (2018-), LS500h (2018-) - combines HSD with a 4-speed planetary gearset. Has pre-programmed 10-Speed shifts.
A Veco .19 engine was chosen for its ability to deliver power at any given RPM. Bill experimented with a 4:1 direct drive gear ratio and finally settled on a 6:1 ratio. Using 3 + 3 ⁄ 4-inch diameter rear tires, Bill achieved a 600 to 2,500 RPM range resulting in speeds from 6 miles per hour to 29 miles per hour.
Gear train. Transmission of motion and force by gear wheels, compound train. [ 1] Illustration by Georgius Agricola (1580) showing a toothed wheel that engages a slotted cylinder to form a gear train that transmits power from a human-powered treadmill to mining pump. A gear train or gear set is a machine element of a mechanical system formed by ...
