1) The advantages of a chain over a belt drive relating to arc of contact and speed ratios are: Slip free, positive engagement of sprocket teeth / chain links. Negligible stretch from real time power transmission. Durability; heavy-duty metal construction withstands hostile environment.
2) The advantages of a chain over a belt drive relating to arc of contact and speed ratios are: Slip free, positive engagement of sprocket teeth / chain links. Negligible stretch from real time power transmission. Long operating life with proper lubrication and maintenance. Durability; heavy-duty metal construction withstands hostile environment. Unlimited shelf life with adequate preservation. And lastly, 'in place' maintenance or repair capability.
3) The five disadvantages of chain drive systems are the noise, elongation, limited flexibility, lower speed limitations, costly sprocket replacement.
4) Pitch is a distinguishing characteristic. It determines the distance between flexing joints or pin centers. The larger the pitch is, the higher the load rating. Conversely, smaller the pitch, the smoother and quieter the operation. A smaller pitch is capable of higher speeds than a larger pitch.
5) A connecting link is used when linking a chain together to make a closed loop.
6) A silent chain uses an inverted tooth.
7)
8) High power transmission with a single strand can be accomplished with an Engineering steel chain.
9) There are three different types of lubrication methods
