How long is the working life of the single shift gear Lh and the working life is 10 years
Formula for calculating stress cycle times of gear N=60njLhexampleLh=2*8*300*15300 is the number of days to work each year, 15 is to work for 15 years, and the 2 is the gear rotation a week, teeth face meshing times. 8 is the 8 hour work system
The application of gears in transmission has appeared very early. At the end of the nineteenth Century, the principle of expanding the cutting method and the special machine tools and cutting tools used in the cutting of the teeth were presented one after another. With the development of production, the stability of gear operation has been paid attention to.
However, the answer cannot be calculated because the quantity is known to be inadequateA mechanical element with teeth on the flange that continuously engages and transmits motion and power
The formula is as follows:Lh= years of work * number of days per year * number of hours per day of work
