Chains 2 Flashcards
Describe hollow pin chain
Hollow pin
Accepts attachments
Standard sprockets
Larger the pitch…
Stronger the Chain
Side bow chain key points
Also known as Curve chain and radius chain.
Clearance built in to allow flexing
Standard sprockets
Down side is backlash
Leaf chain key points
Cable chain, and counter balance chain.
No bushings, rollers or sprockets
Sheave
Push pull or lift
Used on tow motor, counter weight, elevators etc.
Silent Chain key points
Aka, inverted tooth chain
Highest load capacity and speed rating
No strands
Center grove for location
Not a standard sprocket
Since there is no place for sprocket teeth engagement on leaf chains how are they driven?
Sheave
Engendering class chains
2 things to remember
Higher safety factors
2” + pitches
Drive chain
Used for power transmission
Small rollers to improve interaction with the sprocket
High speed short distances between sprockets compared to conveyer applications.
Roller Conveyer chain
Used to convey bulk material, parts of assemblies of parts.
Normally designed with with attachments to connect the carrying device, (top plate, pan, cradle paddle etc. to the chain.
Constructed of pins, bushings, rollers, side bars, and typically attachments
Bushed Chain
A conveyer chain with no roller
Welded chain
Bush chain but the bushings are welded.
No rollers
Bar and pin chains
Same as leaf chain
No bushings, no rollers, or sprocket
Sheave
Push, pull or lift
JUST LIFTS HEAVIER SHIT than a leaf chain.
Barloop chains
- Designed for economy
High strength and flexibility
No rollers or bushings
Used for overhead conveyer systems
Easy to change because of connecting link/master link
Detachable link chain
Like a barloop chain but but hand assembled. Can be detached easily for replacement. Not as precise as a bar loop chain.
Silent chain
Aka inverted tooth chain
