A drive chain is an annular metal chain used to transmit power. Combined with thin gears called sprockets and pulleys, it transmits power from the input shaft to the output shaft.
It consists of a plate that supports the load, a bushing that serves as a bearing for the pin and pin, a roller that protects the bushing, and grease with a lubricating action that is sealed between the pin and bushing.
The size is indicated by a three-digit number using the inch table system. For example, a chain with a pitch of 5/8" between frames and an inner pin width of 2.0/8" would have a chain size of "520".
Drive chains are often used in industrial products that require precision in movement.
For example, they are used in engine timing chains, transfers of 4-wheel drive vehicles (which transmit driving force to the front and rear wheels), power transmission between transmission and drive wheels of motorcycles, and forklifts of chainsaws and forklifts.
Drive chains are also used in a wide variety of other fields, such as power transmission in continuously variable transmissions (CVTs) in automobiles, and in drum kits for kick pedals of bass drums and high-hat cymbals.
Drive chains have many characteristics, such as little pulsation during power transmission due to cutting or elongation/contraction caused by deterioration, few restrictions on the distance between input and output shafts, adaptability to changes in angle and distance between shafts by using an auto-tensioner, and resistance to shock and tensile stress.
Other power transmitters include rubber belts, gears, and shafts. Among these, drive chains tend to be used more often in products used in daily life, such as automobiles and motorcycles, because they offer a relatively good balance between "reliability" and "cost.
However, when replacing a chain, it is necessary to replace the "meshing sprockets, tensioner and chain guide that touch each other, and lubricating oil," so if the chain is used for an extremely long period of time or in a harsh environment, the running cost is not much different from a rubber belt, gear, or shaft, or even more expensive than a rubber belt, gear, or shaft. In terms of running costs, they are not much different from rubber belts, gears, or shafts, or even more expensive.
In addition, periodic lubrication is required for lubrication and maintenance.
In particular, engine oil, transfer oil, automatic transmission fluid for CVT, and other oils and fats play a role not only in lubrication but also in cooling, shock absorption, and cleaning, so periodic replacement of the appropriate oil or fat for the part used is necessary.
When designing drive chains, the chain should be selected by referring to the conduction capacity table. The following three items are the minimum requirements.
(1) Size of the power to be transmitted
(2) Speed and shaft diameter of the drive and driven shafts
(3) Distance between the drive and driven shafts
The number of shaft revolutions and the shaft diameter is calculated in the same way as the reduction ratio of gears. Since the numerical value of the transmitted power is also obtained in proportion to the reduction ratio, the number of revolutions and shaft diameter of the drive and driven shafts are obtained from the reduction ratio corresponding to the input and output, respectively. Since the distance between the shafts is often affected by restrictions such as housing and interference in the mechanism, it is determined in consideration of the location of use and environmental conditions.
After determining (1), (2), and (3) respectively, the length of the chain is determined from the distance between the shafts and the shaft diameter. The chain length is usually a fractional length, which is rare. However, from the viewpoint of smooth power transmission and accident prevention, the chain must have slack, so the appropriate chain length is determined considering the amount of slack.
To keep the drive chains running smoothly, the distance between the drive and driven shafts must be adjusted to a certain strength. As the chain is moved, it will sag over time due to the stretching of the pins and sprockets. Therefore, regular maintenance should be performed to ensure that the chain is tensioned to the proper strength.
The simplest indicator of proper chain slack is generally to keep chain slack within 2% of the distance between axles. Another method is to push the chain between the shafts by hand and tension it so that the dent is within 2% of the distance between the shafts. If the chain stretches and the number of slack increases, remove the sprockets and trim the chain to shorten it. Once the chain has been shortened, it should not be trimmed a second time but replaced, as its strength will be reduced.
It is very important to maintain proper chain tension not only for smooth power transmission, but also to prevent accidents such as chain breakage or rupture.
