How to measure chain size
Use a caliper or screw micrometer to measure the chain center distance, which is the distance between adjacent pins on the chain. Measuring the chain size is important because different models and specifications of chains have different sizes, and choosing the incorrect chain may cause chain brea...Read more -
How do I know the chain specifications and model?
1. Measure the pitch of the chain and the distance between the two pins; 2. The width of the inner section, this part is related to the thickness of the sprocket; 3. The thickness of the chain plate to know whether it is a reinforced type; 4. The outer diameter of the roller, some conveyor chains...Read more -
Calculation method of chain specifications
Chain length accuracy should be measured according to the following requirements A. The chain is cleaned before measurement B. Wrap the chain under test around the two sprockets. The upper and lower sides of the chain under test should be supported. C. The chain before measurement should stay for...Read more -
Can engine oil be used on bicycle chains?
Can engine oil be used on bicycle chains? The answer is as follows: It is best not to use car engine oil. The operating temperature of automobile engine oil is relatively high due to engine heat, so it has relatively high thermal stability. But the bicycle chain temperature is not very high. The...Read more -
What should I do if the front derailleur of my newly purchased mountain bike is scratched?
The mountain bike front derailleur chain needs to be adjusted. The specific steps are as follows: 1. First adjust the H and L positioning. First, adjust the chain to the outermost position (if it is 24 speed, adjust it to 3-8, 27 speed to 3-9, and so on). Adjust the H screw of the front derailleu...Read more -
What are the main parameters of roller chain transmission? How to choose reasonably?
a: The pitch and number of rows of the chain: The larger the pitch, the greater the power that can be transmitted, but the unevenness of motion, dynamic load, and noise also increase accordingly. Therefore, under the condition of meeting the load-carrying capacity, small-pitch chains should be us...Read more -
What are the main failure modes and causes of roller chain transmission?
The failure of the chain drive is mainly manifested by the failure of the chain. The main failure forms of chains are: 1. Chain fatigue damage: When the chain is driven, since the tension on the loose side and the tight side of the chain is different, the chain works in a state of alternating ten...Read more -
Which one is faster, the driving sprocket or the driven sprocket?
The sprocket is divided into a driving sprocket and a driven sprocket. The driving sprocket is mounted on the engine output shaft in the form of splines; the driven sprocket is mounted on the motorcycle driving wheel and transmits power to the driving wheel through the chain. Generally The drivin...Read more -
How is the transmission ratio of the sprocket determined?
When calculating the diameter of the large sprocket, the calculation should be based on the following two points at the same time: 1. Calculate based on the transmission ratio: usually the transmission ratio is limited to less than 6, and the transmission ratio is optimal between 2 and 3.5. 2. Se...Read more -

How to judge the tightness of motorcycle chain
How to check the tightness of a motorcycle chain: Use a screwdriver to pick up the middle part of the chain. If the jump is not large and the chain does not overlap, it means the tightness is appropriate. The tightness depends on the middle part of the chain when it is lifted. Most straddle bikes...Read more -
What should I do if the motorcycle chain is suddenly tight and loose?
It is mainly caused by the looseness of the two fastening nuts of the rear wheel. Please tighten them immediately, but before tightening, check the integrity of the chain. If there is any damage, it is recommended to replace it; pre-tighten it first. Ask After adjusting the chain tension, tighten...Read more
