Shaft — The shaft connects the turbine to the compressor, and runs most of the length of the engine. There may be as many as three concentric shafts, rotating at independent speeds, with as many sets of turbines and compressors. Cooling air for the turbines may flow through the shaft from the compressor.
This means the output shaft rotates at the same speed as the selected gear, thus determining the gear ratio of the transmission. [16] The dog clutch is a sliding selector mechanism that sits around the output shaft. It has teeth to fit into the splines on the shaft, forcing that shaft to rotate at the same speed as the gear hub. However, the ...
The balance shaft runs off the small gear on the left (the large gear is for the camshaft, causing it to rotate at half the speed of the crankshaft). Balance shafts are often used in inline-four engines , to reduce the second-order vibration (a vertical force oscillating at twice the engine RPM ) that is inherent in the design of a typical ...
In a series of videos, the man responsible for the deadly New Year’s attack in New Orleans discussed planning to kill his family and having dreams that helped inspire him to join ISIS, according ...
President-elect Donald Trump’s Surgeon General nominee caused a gun accident when she was 13-years-old that left her dad shot dead — a tragedy which inspired her to pursue a career in medicine ...
Giselle Smith and Semaj Morris, 17, were both killed on Wednesday, Dec. 11, with Smith's sister Paris Kiper in critical condition
Stiffness of the shaft and its support; Total mass of shaft and attached parts; Unbalance of the mass with respect to the axis of rotation; The amount of damping in the system; In general, it is necessary to calculate the critical speed of a rotating shaft, such as a fan shaft, in order to avoid issues with noise and vibration.
If at first — or second, or third — you don't succeed, try, try again. San Francisco's Jake Moody missed three field goals Sunday afternoon against Tampa Bay, but made one that he needed to ...
