M6.10 Control Cables Flashcards
What are the advantages of cables?
. Weight saving
. Route anywhere
. Setup without backlash
What are the disadvantages of cables?
. Tensions have to be adjusted
. Will wear at points of contact
What are wires twisted into?
Strands
What are strands twisted into?
Cables
What is the fraction and identification of a flexible cable?
3/32 = 7x7
What is the fraction and identification of a extra flexible cable?
1/8 = 7x19
What are lock clads on cables? And good/ thing about it?
. Housing protects cable
. Can’t be bent
. Smooth surface
. Sag is eliminated
What does the groove represent on a turnbuckle?p
Left hand thread
What do pulleys allow?
Direction change
What is the role of fairleads?
Guides/prevents structure contact
What direction and load can Bowden cables use?
. Pull only
. Light loads
What direction can teleflex controls operate in?
Push and pull
What are the 3 teleflex cable types? And their helix winding?
23/2 - left hand helix winding
380 - right hand helix winding
169330 - hot areas
What angle is single entry fitting limited to and minimum.
Limited to 270 degrees, minimum 40 degrees
What angles do a double fitting operate at?
90, 120, and 180 degrees
What loads can straight lead units not have?
Heavy loads
How many components does a junction box have and what direction?
2 components, can reverse direction
What does an anti torsion tube prevent?
Twisting
What does a quick break unit do?
Easy removal of components without disturbing control
How is a cable constructed
Wires are twisted into stands and strands are twisted into cables
Which of the following cables are flexible and which are non flexible
1x17
1x19
7x7
7x19
1x 19 and 1x17 are non flexible
7x7 and 7x19 are flexible
When are pulleys used
When there’s a change in direction
Where would a lock clad cable be used
In straight runs
What are the benefits of having a lock clad cable
They reduce sag and vibration
What are fairleads used for
To guide the cables and prevent contact with the structure
What is the purpose of cable turnbuckles
They facilitate cable tensioning
What does the groove indicate on a turnbuckle
That it’s a left hand thread
What’s a DS 23/2
A left hand helix wire
What’s a DS 380
A right hand helix wire
What is the DS169330 similar too and why
The DS 23/2 because it’s a left hand thread also
What’s a quick break units purpose
To facilitate quick disconnection of components which allows the removal of components without disturbing the control
