Hello,
I recently designed a mechanism with a 4-start left-handed trapezoidal thread where the nut translates linearly.
The nuts is brass H62 and the leadscrew is SS 304.
Pitch is 1.5mm; lead is 6mm
Major diameter is 8mm.
Coefficient of friction (brass on steel, dry): 0.51
According to my...
Hi everyone!
I'm designing a mechanism that makes use of shafts. I have two questions:
1.We are locking a 45 T, 0.5M gear in place on a dia 4 mm shaft using two flats (180 degrees apart) on the shaft and two setscrews. The torque is ~120mN.mm and we have already tested out this arrangement on...
Hello all,
I'm working on improving an existing system that consists of 2 water bags hung on an elevation below a peristaltic pump. A single solenoid valve controls the flow through both tubings (Image attached).
1. Upon repeated operations of this arrangement, we observed that an airlock...
