What is the diameter of the 16B chain roller?
Pitch: 25.4mm, roller diameter: 15.88mm, customary name: inner width of link within 1 inch: 17.02. There is no 26mm pitch in conventional chains, the closest one is 25.4mm (80 or 16B chain, maybe 2040 double pitch chain). However, the outer diameter of the rollers of these two chains is not 5mm, ...Read more -
Causes of broken chains and how to deal with them
reason: 1. Poor quality, defective raw materials. 2. After long-term operation, there will be uneven wear and thinning between the links, and the fatigue resistance will be poor. 3. The chain is rusted and corroded to cause breakage 4. Too much oil, resulting in severe tooth jumping when riding v...Read more -
How are chains generally damaged?
The main failure modes of the chain are as follows: 1. Chain fatigue damage: The chain elements are subjected to variable stress. After a certain number of cycles, the chain plate is fatigued and fractured, and the rollers and sleeves are impacted by fatigue damage. For a properly lubricated clos...Read more -
How can I tell if my chain needs replacing?
It can be judged from the following points: 1. The speed change performance decreases during riding. 2. There is too much dust or sludge on the chain. 3. Noise is generated when the transmission system is running. 4. Cackling sound when pedaling due to dry chain. 5. Place it for a long time after...Read more -
How to check the roller chain
Visual inspection of the chain 1. Whether the inner/outer chain is deformed, cracked, embroidered 2. Whether the pin is deformed or rotated, embroidered 3. Whether the roller is cracked, damaged or excessively worn 4. Is the joint loose and deformed? 5. Whether there is any abnormal sound or abno...Read more -
What is the difference between long and short roller chain pitch
The long and short pitch of the roller chain means that the distance between the rollers on the chain is different. The difference in their use mainly depends on the carrying capacity and speed. Long-pitch roller chains are often used in high-load and low-speed transmission systems because of the...Read more -
What is the material of the chain roller?
Chain rollers are generally made of steel, and the performance of the chain requires high tensile strength and certain toughness. Chains include four series, transmission chains, conveyor chains, drag chains, special professional chains, a series of usually metal links or rings, chains used to ob...Read more -
Test method for the chain of transmission chain
1. The chain is cleaned before measurement 2. Wrap the tested chain around the two sprockets, and the upper and lower sides of the tested chain should be supported 3. The chain before measurement should stay for 1 min under the state of applying one-third of the minimum ultimate tensile load 4. W...Read more -
What do A and B in the chain number mean?
There are two series of A and B in the chain number. The A series is the size specification that conforms to the American chain standard: the B series is the size specification that meets the European (mainly the UK) chain standard. Except for the same pitch, they have their own characteristics i...Read more -
What are the main failure modes and causes of roller chain drives
The failure of the chain drive is mainly manifested as the failure of the chain. The failure forms of the chain mainly include: 1. Chain fatigue damage: When the chain is driven, because the tension on the loose side and the tight side of the chain is different, the chain works in a state of alte...Read more -
What does sprocket or chain notation method 10A-1 mean?
10A is the model of the chain, 1 means single row, and the roller chain is divided into two series, A and B. The A series is the size specification that conforms to the American chain standard: the B series is the size specification that meets the European (mainly the UK) chain standard. Except f...Read more -
What is the calculation formula for roller chain sprockets?
Even teeth: pitch circle diameter plus roller diameter, odd teeth, pitch circle diameter D*COS(90/Z)+Dr roller diameter. The roller diameter is the diameter of the rollers on the chain. The measuring column diameter is a measuring aid used to measure the tooth root depth of the sprocket. It is cy...Read more
