Kyle
thanks for the confirmation-comments
i have created a LOOP in the chain as shown in pic 4 above. this encircles the lifting bar and works remarkably well.I hope a 428 chain should lift 80kgs with no problem
cheers Richard
Dave s shown?
if i increase the TOP sprocket from an 11 to say a 15 will that further reduce speed but increase lifting power?
and do you see any problem with the lifting racket being fixed to the chain ( as in last photo ) or should this be run off a different shaft????
thanks again
Richard

i thought my diag shows a 11 driving an 11 then a 25 fixed to same jackshaft driving the top 11.
I assume ive got it horribly wrong BUT re reading your initial post i thought i had followed your plan.
is it possible for you to sketch WHAT you actually mean please . As stated the ONLY...
Hi Compositepro
i see where you are saying the tie-rods are thin but have nothing to do with the lifting part of the machine and are only stabilizers and yes i agree the plates are thin. This is a prototype and had to add the plates to achieve the tie-rod position.The final the top "plate" will...
Hi Compositepro
Can you expand on your comment
all the circular rails are solid carbon steel linear shafts the main ones are 30mm d and the rest 25mm d These have internal threads connecting them to the top and bottom plates ( 4mm 304 stainless plate)all bolts are grade 12.9
all the shafts are...

Thanks for your ideas. Im having a blond moment. Are you saying that if i have an 11 tooth on motor output driving a 25 tooth on jackshaft ( this is one complete drive circuit)
NEXT
if i then run an 11 tooth from jackshaft (output) to an 11 tooth at the top ( 2nd drive circuit) and i...
Hi
I have a machine in progress where i have a 200W 12vDC motor going thru a reduction box at 1:80 (final speed 27rmp) giving 40N.m ( 400kgf.CM )I am using an 11tooth 428 sprocket to drive a jackshaft off this reduction box.
I have a final lifting weight of 80kg which will be lifted by the final...
Hello
IM normally quiet smart but the following has me stumped. My Carpentry brain just cant work it out
I have a machine that has a 200x 20mm sliding plate ( slides on 2 SGB20N bearings each end) it has a vertical load of 400N each side
I need to get this plate to slide(powered) from one end of...
Guys
thanks for the replies and diags
assume the 2nd diagram is the correct gearing ?7:4
the middle gear is to reverse the rotation direction only
Richard
Thanks Ted
If im understanding A and C would have fixed racks with a pinion mounted on B ( catching both racks )
I was thinking of using 2.0 mod track
Any idea on the no of teeth on pinion to convert the 2 different travels.
Thanks
Hi
I have a problem that i hope someone can help me with
I have 3 items
item C is a fixed plate with a length of 900mm
item B is a plate 900mm long it is connected to C with linear bearings and needs to move a total of 400mm . This happens already by using a linear actuator that is connected to...
