Course objectives:
|
The aim of the coarse is to provide students with informations about basic and complex transmission mechanisms:
- To teach students to fundamental properties of the transmission mechanisms and shapes, sizes and materials which are produced from
- To apply knowledge of mechanics and stress-strain analysis at the design and checking of transmission mechanisms
|
Requirements on student
|
Conditions for evaluation of seminar coarse and credit:
- Minimal 75% participation in seminars, 7th and 11th week compulsory attendance
- Handover of two sketch tasks in the required date and time and quality
- Two written seminar test
- Fulfilling all given tasks in the required date and time
- Credits composed in the previous academic year will not be accepted.

Content
|
The course is intended to give students a good insight into the following areas:
mechanisms, basic facts; spur, bevel, worm gears; motion screws and nuts; chain drives; friction and belt drives; gears, basic facts. During the seminars students practice gearbox design and perform computations for typical gearboxes, both in the traditional manner and with the aid of computers; results are tested and verified in the laboratory.
The lecture topics:
1. Transmission, basic facts. Direct-link (three-member) gears using shaped elements. Law of gearing.
2. Spur gearing, geometry characteristics of uncorrected external gearing.
3. Correction, division into individual wheels. Dimensions of corrected wheels, engagement line, engagement duration. Helical tooth geometry.
4. Geometry of direct gearing - internal gearing.
5. Building structure. Accuracy of gearing. Properties.
6. Knowledge for design and control, gear wheels materials. Force conditions in gearing. Dimensioning and strength check of spur gears.
7. Bevel gears. Geometry and dimensions. Engagement conditions, correction. Force conditions in gearing. Dimensional and strength check.
8. Screw gears, cylindrical. Theoretical background, geometry. Engagement ratios, efficiency.
9. Worm gears. Geometry, main dimensions of spinal and general worm. Efficiency. Force conditions in gearing. Dimensioning and strength check of worm gear.
10. Motion screw - motion nut.
11. Friction gears. Gears with indirect coupling (four members) using shaped elements.
12. Transfers with indirect link (4-member) using friction.
13. Gear mechanisms - gearboxes
