Tutorial: Calculation of a two stage gearbox This tutorial shows the usage of MESYS shaft calculation with systems of parallel shafts A two stage gearbox is defined using the program Please start with the tutorial for shaft calculation to see how to introduce geometry and supports for single shafts System Data
Apr 24, 2014· If this clutch slide right and mesh with second gear, then the vehicle runs on second gear speed So in constant mesh gear box we can change the gear ratio by shifting the dog clutch This type of gear box is more popular than sliding mesh because it creates low noise and less wear of gears
The function of the industrial power transmission gear drive is to reliably transmit torque and rotary motion between a prime mover and a driven piece of equipment at acceptable levels of noise, vibration and temperature When one or more of the preceding operating characteristics exceeds allowable limits.
Gear Gears keep the industrial world moving Rexnord Gear Drives are dependable, heavy-duty, and precision engineered to meet the needs of the industrial market Rugged designs hold up to every operating challenge and most are backed by an unsurpassed heavy duty three-year warranty Rexnord is the industry leader when it comes to reliability .
