WHAT IS ROLLER CHAIN?
Roller Chain is a chain that can be used directly and in an efficient way to transmit power between the parallel shafts.
HOW TO WORK ROLLER CHAIN?
The roll will rotate the tightened bushings on the inside of the connecting plate
Pin will prevent the outer connecting plate from spinning with very tight mounting
The chain will hook on the sprocket and continue the power without slip and guarantee a fixed rotation ratio.
FUNCTION AND EXCESS ROLLER CHAIN
Able to pass on great power because of its great strength
Does not require initial voltage
Small wear on the pads
Installation is easy and the price is cheap
Many size variations can be used for large and small power
It does not pose a fire hazard
Not affected by high temperature due to oil and grease
Used when a positive transmission is required and speeds up to 60 m / min.
LACK OF ROLLER CHAIN
Unavoidable speed variation due to arc path on the sprocket linking the chain
Sound and vibration due to collisions between the chains and the base of the tooth of the sprocket
Extension of the chain due to wear and tear of the pen and bushing caused by friction with the sprocket
ROLLER CHAIN DESIGN ASPECT
Pen, bushings and roller materials are used carbon steel or chrome steel with surface hardening
Lubrication is a very important thing for roller chain design
For high horsepower can be used more than one layer chain (Multistrand)
Generally the chain has a cover of metal to protect from dust and to allow lubrication.
ROLLER CHAIN LOOKING TYPE
Manual Lubrication: applied periodically with brush or spray at least every 8 hours
Drip Lubrication: Oil drops are continuously dripped onto the sidelines of the connecting plate
Bath Lubrication: But the bottom of the chain path passes through an oil bath in the driving house. The oil level should reach the pitch line from the chain at the lowest point
Oil Stream Lubrication: Lubrication is provided by circulating the chain in a continuous oil stream.
ROLLER CHAIN CALCULATION
D = pitch diameter (inch)
R = pitch radius (inch)
p = pitch chain (inch)
n = number of sprocket teeth
Lp = Chain Length (Number of links)
Z1 = Number of small sprock teeth
Z2 = Number of large sprock teeth
C = the distance of the axis of the shaft expressed in the number of links.
Chain Speed (v):
P = pitch chain distance (mm)
Z1 = number of small sprock teeth
N1 = small sprocket spin
