Selection of gearbox for rotating a solid shaft

Click For Summary
SUMMARY

The discussion focuses on selecting a gearbox for a solid shaft with a diameter of 320 mm and a length of 805 mm. Key calculations include determining the torque of the shaft and the gearbox, which are essential for proper gearbox selection. The moment of inertia for the shaft is calculated using the formula 1/2mr², where 'm' is the mass and 'r' is the radius. Additional parameters such as power output from the motor and angular velocity are also critical for accurate gearbox selection.

PREREQUISITES
  • Understanding of torque calculations for rotating shafts
  • Knowledge of moment of inertia and its application in mechanical systems
  • Familiarity with gearbox specifications and motor power output
  • Basic principles of angular velocity and its impact on mechanical design
NEXT STEPS
  • Research the calculation of torque for rotating shafts in mechanical engineering
  • Learn about gearbox selection criteria based on torque and power requirements
  • Study the moment of inertia for various shapes and its relevance in design
  • Explore the relationship between angular velocity and gearbox performance
USEFUL FOR

Mechanical engineers, design engineers, and anyone involved in selecting gearboxes for rotating machinery will benefit from this discussion.

Hello
Being practical I have been stuck in one question like if I have a 320 mm diameter and 805 mm long shaft which is suppose to rotate through gearbox how do I need to select a gearbox.
As per I think I need to calculate the torque of shaft and find the torque of gearbox and based on that I will select gearbox.
I just want to know the basic formula to calculate torque of shaft and torque of gearbox assuming that it has a flange mounted motor so again how much power we need for that perticular gearbox

Without seeing the question it's hard to determine what the actual answer is. Because you are talking about angular velocity and given the values you have provided you most likely need to calculate the moment of inertia which for a cylinder is 1/2mr^2. However you still need parameters such as mass, power output from the motor, angular velocity of the motor. You must have additional parameters in the question
