Re: Can a clutch be engaged at speed or zero speed?

Can a clutch be engaged at speed or zero speed? I guess it depends on what kind of clutch you are talking about. What kind of clutch is of interest to you? Typical single surface clutches can be engaged at zero speed with no problem. The only clutches that "could" have a problem engaging at 0 rpm ar...

Re: Robotics

The brakes are getting thinner by the minute.

Also, there is a growing ability to make them smaller. 8mm OD is super tiny for a motor brake (low torque but high speed).

Re: Have servo drives eliminated ball-detent torque limiters from new OEM designs?

If we are talking large torque, how about shear pins? Some of the mills still use those somehow. :roll: R+W's SK looks like they have a pretty wide range. Torque to 2800Nm with precision. I guess there are many ways to solve a problem... mechanical, electrical, or something else. We just try to pick...

Re: What PTO Clutch on a new ZTR Purchase?

Hey Will, In my opinion, the folks that build these mowers put many hours into design, testing, approval of the components, engines, belts, clutches, etc. Although the different brand ZTR mowers may look somewhat the same, there are subtle differences that make them perform differently, so the clutc...

Re: Linear actuator braking

Here is a fun way to use a vertical linear motor. I believe the machine's intention is to make you sick. It uses an Aerotech BLMX linear motor. https://www.youtube.com/watch?v=lR_uF6fPWLA&feature=youtu.be Regarding heat...taken from Aerotech's installation manual: The motor’s temperature rise above ...

For ships and mining

For the high torque jobs, you need a high torque clutch. Here is a quick 1 minute video from Dellner showing hydraulic clutches for ships and mining apps. I feel like it is time for a cruise.
