    Hi all...

    Please check the questions..

    1. What you would do if you had to install a clutch on a slow speed engine ?
    2. What would happen if the boat had 2 twin slow speeds, would you need to lock each shaft when not in operation when one engine broke do or was not in service? What is the significance of the Torque equation T = u F Rf n ?
    3. Would you install flexible couplings on a clutch and why?

    It would be great if any one can answer any above questions ?

    these questions sound more suited to commercial vessels - maybe check other forums.
    1/slow speed engines would not typically be provided with a clutch. the advantage slow speed engine is direct drive of propeller at slow speed through fixed shafting (no gearbox). if clutch to propeller installed would need to be inline
    2/depends on whats wrong with engine. you wouldn't get in crankcase or touch running gear but external works ok. some vessels have shaft locking devices but not safe at decent vessel speed.Torque formula can be obtained from any textbook or a quick search on web
    3/yes due to fitted with smaller engines and gearboxes.reasons include expansion, alignment and flexibility to drive say shaft generator or only engine while not running prop.

    To install a clutch you need to look for clearance, torque and maximum RPM and size accordingly

    Well teddy it was something about he post ...the mangled miss spelt english ..the lack of anything technical . perhaps often I am too keen to help when I am out of my depth but I hate helping idle people who would rather rattle the keyboard than do any actual work ....and so it transpired..Perhaps you are right no one should have responded.....
    Gonzo says read your textbooks
    The dutch touch says ..do your own homework ..
    so I am not alone
