Course Description

 

 

Fundamentals of speed reduction mechanisms, kinematics and geometry of gears, spur, helical, bevel, spiral and worm gear mechanisms, belt drive and chain mechanisms.

Objectives

 

 

 

1. To introduce form connected speed reduction mechanisms and their kinematics.

2. To give constructive characteristics and design methods of gear, worm, belt and chain drives.

3. To improve knowledge and capability by projects.

4. To give fundamentals of synthesis phase of design.
Outcomes

 

 

 

 

 

At the end of this course, students should be able to:

1.      Recognize force related power transmission mechanisms to introduced to form connected power transmissions (speed reduction mechanisms). Recognize basic rule of gears and determination sliding speed, finding profile of the mating tooth profile, line of action and contact ratio, interchangeability.

2.      Recognize teeth profile used in the power transmission mechanisms with constant velocity ratio.

3.      Recognize kinematics, contact ratio, the minimum tooth number, undercutting and calculation of tooth thickness, gear dimensions and their standards of evolvent profiled gears.

4.      Recognize calculate of the profile shifted gears (extended center distance gears).           

5.      Recognize strenght calculations and determination of the dimensions of spur, helical, bevel and spiral gears and worm gear mechanisms.

6.      Recognize flat and V-belt-pulley mechanisms, selection and calculation methods and standards of them. Recognize application and selection of toothed belts.

7.    Recognize chain mechanisms and chain types, calculation methods and standards of them.

8.      Make projects.
