Flashcards in Couplings Deck (13):
1

The purpose of couplings

To connect 2 shafts

2

Types of couplings

Rigid, flexible, universal joint, fluid, and magnetic

3

Purpose of rigid couplings

When shaft need to be precisely aligned, bearing support is necessary, and alignment must be maintained

4

Types of rigid couplings

Flange, sleeve, and ribbed

5

Purpose of flexible couplings

Accommodate for misalignment

6

Types of flexible couplings

Gear, chain, grid, flex disc, and elastomeric

7

What degree of misalignment is maximum?

1 - 3 degrees

8

What is misalignment?

Angular or parallel shifting of the two shafts

9

How many axis points can a shaft misalign?

12

10

Couplings are designed to be the first to what?

Break

11

Types of elastomeric couplings

Jaw, Wrap flex, and Rubber tire

12

U-joint purpose

Allows for transmission of power at larger angles, up to 30 - 40 degrees

13

Types of U-joints

Block and pin/bearing and cross
