Mechanical Engineering Design III assignment involving the design of a geared industrial roll (two high). The roll is driven at 350 rev/min by a force F acting on a driven gear. The roll exerts a normal force of
60kN/m of roll length and a pull of 50kN/m on the material being processed.
The material passes under the roll. The coefficient of friction is 0.40. A design
life of 35 kh is desired. Use angular-contact ball bearings for the support to get
a combined reliability of at least 0.92. Select standard size for the shaft. The
drive gear is spur having 20° pressure angle. Assume suitable reduction ratio
and select the drive motor for the mill. Please use this file as guide. For similar projects, please visit http://www.topengineeringsolutions.com/
