An interesting "press release" just appeared on the Synkinetics www site (www.synk.com). Does anyone here know much about their technology or what this press...
Hi: I am the motorized bicycle CVT guy, see photos MoBike CVT. Being a nuts and bolts type, I need some tech help with a project problem involving a drum...
hi bill, It looks indeed that you have a tribological problem. I guess this shudder comes from a very steep angle on the stribeck curve of the combination of...
This technology is very similar to the "Harmonic Drive" except they use rolling members rather than gear teeth. The Harmonic Drive was patented in the 50's by...

Agree James Also, similar devices are made by, among others, mitsubishi. I think they call theirs the cyclo, and if I remember, aslo has conjugate acting...

Pushbeltman: Thanks for the direction. Your stribeck curve insight, especially regarding the steep angle and square root of the roughness has given me an idea...
intermittent problem - with car in gear (D or 1st)gear doesnt engage- engine just revs -is it the auto control box? ie elecrtical rether than mechanical fault?...
* Hi all. This type of transmission is similar is a epiciclyc system, only that all the set is not geared, but it communicates by friction, and also the...
Pushbeltman: I am always glad to learn a few things myself. The answer to this shuddering clutch problem, with powdered Iron shoes and hardened steel drum, was...
hello hawkeye, You don't give us much to go on. Does the engine also rev up in Low (L)? If it does you might have a problem with your clutch. Or do you hear...
on the limited info, sounds like a torque converter problem. How about checking the atf fluid level for a start. however, can be mechanical or electrical too....

Hi. My son and I are in the early stages of an electric motorcycle project--adapting a conventional motorcycle to run on an electric motor and batteries. Most...

Mygyro: Sounds like a fun and educational project. Take a look at the Comet Torque A Verter I used on my bike, see group photos MoBike CVT. Comet makes...
... Many CVTs in ATVs and scooters and things are mechanically controlled, which is better than direct drive, but isn't as ideal as an electronically ...
My thoughts: Electric motors real problem is in the startup torque. Thereafter they dont really mind changing speed. If it was me, I'd be inclined to use no ...

The idea of an electric motor cycle is a good one. But doing away with the transmission IS possible without wasting energy if the proper motor is selected. For...
... start ... engage- ... rether ... Hi there, thanks for replying... reverse seems ok. same thing can happen in L and yes, there is a faint metal to metal...
HI Dudley, thanks for replying. ATF is fine. I checked all linkages today and they are perfect(this car has only done 33,000 Miles) but we are not 1st owner-...
I agree with Dudly. It seems that the goal is to have the teeth be 'floating' and so if they are in a position of striking rather than smoothly meshing then...
Walter tells me their CVT is working well, albeit with a slight oscillation in geared neutral. It works smoothly in all ratios, but is a 'low power' model that...
Ken, I am not sure you understand the operation of this IVT. What teeth are you referring to as floating and in which plane? In operation they do mesh smoothly...
hello hawkeye, Thanks for the additional info. My first guess is the clutch engagement. You have a problem in forward direction (Low&Drive) but not in Reverse....
What teeth are you referring to as floating and in which plane? From a previous email; "During this time the cones are still held in time to each other, but...
hi,pushbeltman thanks a lot for this information I intend to take the box out tomorrow so your advice comes at the right time. I'll get back to you whenever...
Something that should perhapes be clarified..in the drawing it seems as if the cones gear teeth have the same width teeth, both the raised part and the...
Ken, I appreciate your interest and comments, but I believe we are not both on the same track regarding my CVT/IVT. So please bear with me while I try to...
it is obvious we have similar interests in things It would seem so. What teeth are you referring to as floating and in which plane? I was thinking that you...
Ken, not much time I will finish later- see in red Ken James <nautikat@...> wrote: it is obvious we have similar interests in things It would seem so. ...
They are always the same pitch as the sliding ring gears pitch. On the cone diameters that have an integer number teeth I am sure you have no problems with....
