Escalator driving chains
● Escalator drive chain is divided into main drive chain and handrail belt drive chain, which are designed according to ISO 606 standards, and its interchangeability dimension is consistent with standard roller chains, mainly A series, B series roller chains, and its reinforced chain.
● Using high-quality materials and advanced processing technology, the product has the characteristics of high tensile strength and high fatigue strength; The tensile strength of the reinforced main drive chain reaches 1.2 times the minimum tensile strength of ISO standard, and the fatigue strength reaches more than 1.6 times the minimum dynamic load strength of ISO standard.
● The products are matched with well-known escalator host manufacturers at home and abroad and are widely used in various subway stations, high-speed railway stations,s, and other rail transit and shopping malls escalators, among which the reinforced main drive chain is mainly used in public transport heavy-duty escalators.

Selection of chain drive power
The standard of "Guidelines for the Selection of Roller Chain Drives"(GB/T 18150-2006 / ISO 10823:2004) has been issued. If you try to calculate the actual transmission power of the chain, you must consider revising the transmission power of the driving sprocket (input power).
Actual power(Corrected power)=input power × service factor × teeth factor Service factor is listed in the following table.
Teeth factor = (19/Zs)1.08 (Zs—tooth number of the small sprocket)

Factories with a long history in the world have their chain transmission power rating graph and power diagram. We can refer to the GB/T 18150-2006 / ISO 10823:2004 standard selecting the drive power or selecting the chain according to the drive power, the condition is that we should know the tooth number of the small sprocket and its speed. Only if the actual power is within the range of rating power of the power rating graph, the selected chain is suitable.
Now we use the transmission part in the walking tractor and the transmission power in rotary tillage to prove whether the chain selection is correct.

Chain drive part
Small sprocket speed ns=1351 r/min Tooth number of small sprocket Zs=14
Actual power (Corrected power)=10.944hp=8.16kW
From the B series horsepower rating graph, you will find that the selected 08B-2 chain is suitable.

Ratar y tillage chain part
Small sprocket speed ns=199 r/min Tooth number of small sprocket Zs=13
Actual power (Corrected power)=9.888hp=7.37kW
From the A series horsepower rating graph, you will find selected 12A-2 chain is unsuitable. You should choose a 16A-1 or 60H-2 heavy-duty roller chain instead of 12A-2.

The main characteristics of this power graph are as follows:

Maintenance for Roller Chain Drive
t’s very practical to illustrate the convention- al maintenance of roller chain drive because of its wide application in industry. Better maintenance, less failure. In practice, only following some simple maintenance principals, we can easily save costs and make its service life longer, and then making the operation more efficient.
1.Each sprocket in the driving system should have good coplanarity and the chain path should always be smooth.
2.The sagging of chain loose side should be suitable and for the adjustable center distance level and angle drive, the sagging should be 1%~2% of the center distance. For conditions of vertical drive and under vibration load、reverse drive and dynamic brake ,the sagging should be smaller. It’s very important to check and adjust the loose side sagging frequently in the chain drive maintenance.
3.Good lubrication is also very important. Whichever lubrication method you choose, the most important thing is to make the lubricating grease distribute evenly in each chain joint clearance. If not necessary, avoid selecting big viscosity heavy oil or lubricating grease since it will jam the clearances gone to joints friction surface with dust after a period of time. Periodi- cally clean the roller chain and check its lubrication condition frequently. Disassembly the pin and bush, if necessary. If the friction surface is brown or dust color, it may be caused by insufficient lubrication.
4.Chains and sprockets should be always in good condition.
5.Frequently check the working surface of sprocket teeth ,adjust or replace it when it’s excessively worn.

Troubleshooting Instructions
Failure Symptom Possible Causes Actions
 
Roller cracked or deformed
1. Too big chain pitch or too small number of sprocket teeth
2. Sprocket teeth have foreign bodies. 3.The chain climbs onto sprocket teeth too high.
4.Excessive chain impact load
1. Select small pitch chain or add sprocket teeth number
2. Remove all the foreign bodies or replace chain 3.Replace the chain and make appropriate tensioning 4.Reduce the impact of chain
