Flashcards in Couplings Deck (13)
The purpose of couplings
To connect 2 shafts
Types of couplings
Rigid, flexible, universal joint, fluid, and magnetic
Purpose of rigid couplings
When shaft need to be precisely aligned, bearing support is necessary, and alignment must be maintained
Types of rigid couplings
Flange, sleeve, and ribbed
Purpose of flexible couplings
Accommodate for misalignment
Types of flexible couplings
Gear, chain, grid, flex disc, and elastomeric
What degree of misalignment is maximum?
1 - 3 degrees
What is misalignment?
Angular or parallel shifting of the two shafts
How many axis points can a shaft misalign?
Couplings are designed to be the first to what?
Types of elastomeric couplings
Jaw, Wrap flex, and Rubber tire
Allows for transmission of power at larger angles, up to 30 - 40 degrees
