Types of Mechanical Connections and Joints in Engineering Technology

This educational program covers various types of mechanical connections and joints in engineering, including shaped, friction, and pre-stress connections. It discusses important joints like shaped joins, friction couplings, and pre-stressed combined shape joints. The program also delves into the connection of materials through welding, soldering, and gluing.

  2. Types of mechanical connections / joints

  3. Types of mechanical connections / joints • Classification

  4. Types of mechanical connections / joints • Important joins: • Shaped joins • Friction joins • Pre-stress joins • Joins with mechanical • contact

  5. Types of mechanical connections / joints • 1. Shaped contacts can be made with: • Tight springs • Grooved shafts and boss / hubs • Matching bolts • Pins • Pivots / Journals • Rivets

  6. Types of mechanical connections / joints • Shaped connections – pins, journals Conical pin with internal thread Flexible pin Journal with head and hole for cotter pinCylindrical pin with safety rings (Seger)

  7. Types of mechanical connections / joints • 2.Power connections – friction couplings • Grip / thrust / joints • Conical joins • Bolt joins • Joins with friction clutch • a)Trust join of shaft and hub • b) Parts joining by bolt pass loaded by a force vertical to bolt axis

  8. Druhy mechanických spojení • 3. Pre-stressed / combined shape joins: • It is a combination of the following types of joins. • Joins with frontal gearing • Conical joins with segment springs • Special case in tis case is wedged connection

  9. Druhy mechanických spojení • Connection of materials – cohesive and adhesive powers are • welding • soldering • gluing • Contact by joining of material • Joined material of the same character and strength as the basic material – welding • b)Joined material have different character and lower strength as the basic material – soldering, gluing

  10. Translate:

  11. Answer the questions: • 1. Type of mechanical joins – basic division • 2. Classify them: • Bold joins • Tight springs joint • Joins with frontal gearing • 3. Is this a picture of grip thrust

  12. Used literature • http://www.ksp.tul.cz/cz/kpt/obsah/vyuka/skripta_tkp/sekce/04.htm • http://cs.wikipedia.org/wiki/Spojen%C3%AD_h%C5%99%C3%ADdele_s_n%C3%A1bojem#Tvarov.C3.A1_spojen.C3.AD_h.C5.99.C3.ADdele_s_n.C3.A1bojem
