SUMMARY

The torque ratio for a gear set with a gear ratio of 3.2:1 is definitively 1:3.2. This means that the output shaft will produce 3.2 times the torque of the input shaft for every rotation of the output shaft. The calculation is based on the inverse relationship between gear ratio and torque ratio, where the gear ratio indicates how many times the input shaft must turn to achieve one complete rotation of the output shaft. Power remains constant, accounting for drivetrain losses.

PREREQUISITES
  • Understanding of gear ratios and torque relationships
  • Basic knowledge of mechanical engineering principles
  • Familiarity with automotive systems and components
  • Experience with torque calculations in mechanical systems
NEXT STEPS
  • Research the principles of gear mechanics and torque transmission
  • Learn about drivetrain losses and their impact on power output
  • Explore advanced gear ratio calculations in different mechanical applications
  • Investigate the effects of gear ratios on performance in automotive engineering
USEFUL FOR

Automotive service technicians, mechanical engineers, and anyone involved in the design or maintenance of gear systems will benefit from this discussion.

Here is my question that I haven't been able to solve.
What would the torque ratio be for a set of gears with a gear ratio of 3.2:1?
And how did you come up with the answer?
 
Physics news on Phys.org
what does a gear ratio mean?
If you apply a torque to a set of gears how does the gear ratio effect that?
 
This is my question.Two gears have a turning ratio of 3.2:1 What is there torque ratio ?
.32:1
1:3.2
3.2:1
32.0:1
And how would you calculate that??
 
By the way I am a 55 year old Automotive service tech so I don't have homework. Just trying to resolve a issue.
 
If the gear ratio is 3.2:1, then the torque ratio is 1:3.2. The output shaft will have 3.2 times the torque of the input shaft if the input shaft rotates 3.2 times every time the output shaft rotates 1 time. Power remains the same except for drivetrain losses.
 
Thank you for your time Jeff
