What is the difference between al and BL leaf chain?
The key difference however is that it’s manufactured to the European standard. BL-LH series (Leaf Heavy) chain is heavier duty chain than AL and EL-LL series and is the only leaf chain that is constructed from specific leaf chain components.
What is bl chain?
Leaf Chain is the most simple of steel chains, consisting only of link plates and pins. This chain generally has greater tensile strength than roller chains and runs over sheaves rather than sprockets. They are suitable for hanging, balancing or motion transmitting applications.
How do you measure the pitch of a leaf chain?
EL-LL and BL-LL series leaf chain is measured in both 8ths and 16ths of an inch. For example, BL12 represents 12/8” and LL24 represents 24/16” which can both be reduced to 1 ½”. The metric pitch can then be found by dividing the numerator by the denominator and multiplying by 25.4 as 1 inch is equal to 25.4 mm.
What is leaf chain used for?
Leaf chains are often used as counterweight chains for machine tools, elevator and oven doors, fork lift truck masts, spinning frames and similar lifting or balancing applications. Plates are connected by pins and hold the tension loaded on the chain.
What is leaf chain?
Leaf chain is a rollerless chain that is commonly used on forklift trucks and in other material handling applications. Leaf chain is constructed of steel link plates mounted side-by-side on pins. The contour of the link is the same figure-eight shape found on standard roller chains. The chain can flex at each pin.
How do I know what roller chain I have?
Most roller chain has the size stamped right into the side plates. You may see something like “40”, “C2080H” or “10B” stamped in, which the industry number that represents the chain size. Old chains will most likely need to be cleaned in order to see the size.
How do I know what kind of chain I have?
How to Tell What Size Chain You Have
- The distance from the center of one pin to the center of the next pin, also known as the “pitch” of the roller chain.
- The diameter and width of the roller.
- Plate thickness, determined by measuring the plates from one flat side to another.
What is a Morse chain?
Another type of drive chain is the Morse chain, invented by the Morse Chain Company of Ithaca, New York, United States. This has inverted teeth. Sometimes the power is output by simply rotating the chain, which can be used to lift or drag objects.
What is a rollerless chain?
– All chain components are heat treated to achieve maximum strength. and greater wear resistance. – All PEER roller chain is pre-loaded during the manufacturing process. to minimize initial elongation.
What are leaf chains?
How do you make a leaf chain?
Fold the paper piece in half widthwise.
- Now, fold the top and the bottom sides in half backward to make it into an accordion fold. (
- Let’s start with the bottom part of the leaf.
- Once the fall leaf is drawn, cut the paper fold along the lines we drew.
- Gently open the fold and you will see a beautiful fall paper chain.
How are roller chains sized?
Roller chain is made in several sizes, the most common American National Standards Institute (ANSI) standards being 40, 50, 60, and 80. The first digits indicate the pitch of the chain in eighths of an inch, with the last digit being 0 for standard chain, 1 for lightweight chain, and 5 for bushed chain with no rollers.
What are silent chains?
In chain. A silent chain is essentially an assemblage of gear racks, each with two teeth, pivotally connected to form a closed chain. The links are pin-connected, flat steel plates with straight teeth. Silent chains are quieter than roller chains, can operate at higher speeds, and can transmit…
In what way silent chain is better than ordinary driving chain?
Silent Chains have higher capacity than roller chains of the same width. Because the link plates of Silent Chain strike the sprocket at an angle, the impact and the noise are reduced (Figure 1.30). This is why these chains are called “silent.” The higher the chain speed, the greater the difference from roller chains.
