There are many types of chains, and there are many differences between them, such as conveyor chains and driving chains.
The main function of conveyor chain is to convey goods, so compared with driving chain, the obvious difference is that the chain speed is slow, but the load is large. In order to achieve such a special requirement, the weight of conveyor chain must not exceed the specified range, and at the same time, it must form a certain proportional relationship with the load it is subjected to. At the same time, the wear resistance must be small, because the number of teeth of the chain wheel is small during the operation, and the angle of rotation between the chain links is large, so it is easy to be worn.
In addition, the conveyor chain must have certain impact resistance, high temperature resistance and reliability to meet the requirements of special working conditions. However, the resistance of rolling cannot be engaged, which is the basic condition to improve the efficiency and service life of conveyor chain.
Then comes the driving chain, of which the representative one is the short-pitch precision roller chain, which is characterized by the pitch increasing to an integer, by a variety of different pitch forms, which can not avoid being blocked by debris, etc. After familiarizing with the characteristics of short-pitch precision roller chain, it is obvious that it can be used.
What are the specific uses of conveyor chains:
Convey chain used for escalator is actually a kind of conveyor chain. Its working principle is that the core part of the escalator is two chains that circulate around two pairs of gears. At the top of the escalator, a motor drives the drive gears to turn the chain loops. A typical escalator uses a 100 horsepower engine to turn the gears. And both the engine and chain system are mounted in a frame, which is a metal structure that extends between two floors.
Unlike a conveyor belt that moves in a plane, a chain ring moves within a set of steps. What is interesting about escalators is the way these steps move. When the chain moves, the steps are always horizontal. At the top and bottom of the escalator, the steps fold over each other to form a platform. This makes getting on and off the escalator much easier.
Conveyor chains can also be used in some conveyor equipment and machinery driven by chains. Such as assembly line and other automatic conveying equipment. Because his chain has the characteristics of large pitch, large middle distance and low chain speed. It has become the technical standard for judgment.
Note on the use of driving chain:
The damage of driving chain is due to its fatigue use, and the result is to make the driving chain fail and endanger the working efficiency. So, what are the things to pay attention to when using the drive chain.
After the drive chain is damaged, you can reverse the drive chain and reuse it on the side that is less damaged. To reduce its damage, you can add grease to each section of the drive chain. Combined, it prevents the drive chain from being used for a long time and also reduces the damage to a lower level.
Using the drive chain for a long time will not only cause excessive damage, but even make the drive chain loose or even misaligned. In order to prevent damage or misalignment of the drive chain, the tension of the drive chain should be improved, and in the end, it is necessary to buy good quality drive chain, so as to improve the production and processing accuracy of the drive chain and the strength of the digging working surface.
We should also pay more attention when installing the drive chain, and install it parallel to the drive chain shaft and properly audit it, so as to reasonably reduce the damage of the drive chain, otherwise it will lead to the deflection of the drive chain shaft and more seriously affect the normal operation of the Tianjin drive chain.
The maintenance steps of chain are basically divided into two steps: cleaning and oiling.
If the chain has a lot of sludge, you should use a brush (or an old toothbrush) and soapy water (warm soapy water is better) to clean the sludge, and then rinse it with clean water, just like brushing shoes and washing dishes, and after washing, remember to dry the chain with a dry cloth.
If the chain is not muddy, you can take it off, find a container, fill it with cleaning agent, put it into the chain and shake it to make it clean, if your chain has a magic buckle, then congratulations, you will finish this maintenance more easily than others.
If you don't want to remove the chain, you can use the chain washer, it is simple and convenient, but note that when cleaning, you must avoid the cleaning solution to pollute the floor, some cleaning solutions are hard to clean.
It is better not to use highly aggressive rust remover, it will erode the chain and make it very fragile and easy to break the chain.
Do not use high pressure water column to remove the sludge on the body, this method is very efficient, but it may force the sewage into the bearing, which will cause damage to the bearing.
Don't use chain oil randomly, you can choose different chain oil according to different riding environment.
In a humid environment, you should use oil with high viscosity, because high viscosity is easier to stick to the chain surface to form a protective film; in a dry and dusty environment, you should use oil with lower viscosity, so the chain will not be easily covered with dust and dirt. And a good lubricant will feel like water penetrating the chain when it is used, but it will become sticky or dry after some time.
Make sure the chain is dry before oiling, otherwise oil and water will mix together and reduce the effectiveness of the chain oil.
If you are only doing a minor maintenance, you can only oil the critical parts of the chain. If it is a big maintenance, every piece of the chain should be oiled, so you should drip oil to both sides of the chain pins one by one when oiling.
It is not better to apply more oil than necessary. Too much oil will attract dust and dirt and increase the wear of the chain. To control the amount of oiling, use a syringe and wait for a few minutes after oiling to let the oil penetrate into the chain and then rotate the drive system several times. If you are using spray can type lubricating oil, remember to wipe off the excess chain oil with a dry rag after oiling.
