Total face width is the actual dimension of a gear blank including the portion that exceeds the effective face width, or as in double helical gears where the total face width includes any distance or gap separating right hand and left hand helices. For a cylindrical gear, effective face width is the portion that contacts the mating teeth.
In mechanical engineering, backlash, sometimes called lash, play, or slop, is a clearance or lost motion in a mechanism caused by gaps between the parts. It can be defined as "the maximum distance or angle through which any part of a mechanical system may be moved in one direction without applying appreciable force or motion to the next part in mechanical sequence."
Bell announced its new project after the Bell 429 and Bell V-22, the super medium Bell 525, previously it was known as Project X or Magellan. The Helicopter is overall designed for trips of 50 to 500 nautical miles, and has a 5-blade main rotor powered by twin engines, digital controls and Garmin G5000H screen, with planned seating for 16-20 people.

The old method of gear cutting is mounting a gear blank in a shaper and using a tool shaped in the profile of the tooth to be cut. This method also works for cutting internal splines. Another is a pinion-shaped cutter that is used in a gear shaper machine. It is basically when a cutter that looks similar to a gear cuts a gear blank.
Cessna launched the $2.4 million (equivalent to $6.09 million in 2024) model 525 CitationJet at the October 1989 NBAA convention in Atlanta, estimating a demand for 1,000 aircraft over ten years. [5] Its first flight was on April 29, 1991, a Federal Aviation Administration (FAA) type certificate was awarded on October 16, 1992, and first ...
The left sun gear (red) provides more resistance than the right sun gear (yellow), which causes the planet gear (green) to rotate anti-clockwise. This produces slower rotation in the left sun gear and faster rotation in the right sun gear, resulting in the car's right wheel turning faster (and thus travelling farther) than the left wheel.
The M51 is a water-cooled and turbocharged inline six-cylinder diesel engine with a Bosch VP37-swirl-chamber-injection.[1] [2] [3] The displacement is 2.5 L; 152.4 cu in (2,497 cc) and the compression ratio is 22.0:1.
The Berkut 360 is a tandem-seating, two-seat homebuilt canard aircraft with pusher configuration and retractable landing gear, built primarily of carbon fiber and fiberglass. The Berkut 360 is featured in the 2010 movie Kill Speed ( Fast Glass ).
