Important joins:Shaped joinsFriction joinsPre-stress joinsJoins with mechanicalcontactTypes of mechanical connections / joints
Types of mechanical connections / joints1. Shaped contacts can be made with:Tight springsGrooved shafts and boss / hubs Matching bolts PinsPivots / Journals Rivets
Shaped connections pins, journals Conical pin with internal threadFlexible pin
Journal with head and hole for cotter pin Cylindrical pin with safety rings (Seger)
Types of mechanical connections / joints
2.Power connections friction couplings Grip / thrust / jointsConical joinsBolt joinsJoins with friction clutch
a)Trust join of shaft and hubb) Parts joining by bolt pass loaded by a force vertical to bolt axis
Types of mechanical connections / joints
3. Pre-stressed / combined shape joins: It is a combination of the following types of joins. Joins with frontal gearingConical joins with segment springs Special case in tis case is wedged connectionDruhy mechanickch spojen
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 Druhy mechanickch spojen
