How to select a right chain?

Hi All;
   Can any expert out there tell me how to select a right chain? do i need a chain graph?

RE: How to select a right chain?

Hi,

Assuming you are trying to spec heavy duty chain then this answer may not help you, but:-

Here in the UK there is a company called HPC Gears, they supply a booklet of there chain and gear sizes. in this booklet it gives you design parameters to allow you to choose the correct chain for any general application. It does make the distinction of having shock loading, etc and so is factored into the calculation process. i know this may not help you out if you live outside the UK, or are needing a quick answer.

Cheers

RE: How to select a right chain?

It might help if you told us what type of chain you are trying to select??
If it's a transmission roller chain these are usually selected from the manufacturers selection charts.

RE: How to select a right chain?

HPC Gears has some good general info - I have a copy on my e-library. Thanks AndyR05.

RE: How to select a right chain?

I am trying to select a duplex chain for a magnetic drum driven by a 7.5 kw motor.
The sprocket and gearbox information are as stated below:

Gearbox
---------
Ratio: 31.39
Output torque: 1570 Nm
Service factor: 1.7
Output speed: 46 rpm
Drive shaft Dia: 60mm, 64mm including key


Pinion sprocket attached to the gearbox
--------------------------------------
No teeth:20
Pitch diameter:159.72mm


Magnetic drum sprocket
----------------------
No teeth:57
Pitch diameter:461.07mm
center distance between two sprockets:1000mm


 Someone had changed the chain recently but when it running it keeps loosing and tensioning until it rip the gear box into half. Can someone please explain to me why it had done that? the chain information is as stated below;

Chain
------
Chain pitch:25mm
Total length:3000mm

Thank you (diskullman) that website does help me a bit to understand how to select a chain but i still need more information to solve my problem.

RE: How to select a right chain?

I would check the drive conditions first, like the bearings on magnetic drum. What has changed recently? If the chain is not breaking, why do you suspect the chain? The gearbox is ripping in half?
