Hello -
I need some support about the best practice to identify the location on a drawing to state where a laser etching should occur.
I haven't specified anything like this before and we do not have an internal standard - looks like I am the first!
I am thinking that I would need to outline...
Thank you both for your interest. Currently it is a prototype so quality is not so good. Contact ratio is 2.0. Geometry is from a very expensive software tool. I would not expect this to be so sensitive.
The intention however is to produce this by injection molding, so will live with a cross...
Hi Folks, I have designed a small DC motor driven actuator that simply arcs a lever back and forth over a 10 mm arc. The system consists of a 1 start worm, and a 28 tooth helical gear. This lever has physical stops at both ends of travel. On occasion when the lever hits one of the stops, I...
This may seem like a concerning question, but I am going to ask it anyways.
Is there such a gear as a spur gear simply cut on an angle?
We are researching the use of helical gear application, but there is some debate about how to model a gear, properly.
I have drafted a sketch (involute) in...
Hello,
I have been struggling to determine the required torque of a motor in a worm gear drive. I have calculated the tangential force that the worm gear applies to the worm, but cannot determine the required torque the motor will require to turn the worm. All searching on the web has...
