Calculating eccentric bearing diameter for wave machine with spring return
Yes it kinda the same. but now I return to my original question - how to design / determine the size and shape of the Cam so it will make only 90°- Haim1404

Calculating eccentric bearing diameter for wave machine with spring return
In this case wlll the following solution work? both gears are the same size but one of them that connected to the motor is 3/4 cut off. since the motor torque is more than I need, I shouldn't have problem or be concerned of it...- Haim1404

Calculating eccentric bearing diameter for wave machine with spring return
Thanks guys for your input! I must understand something that CWatters said: "If it takes 40Nm to rotate the output then that's what the motor will deliver even if the motor can generate more due to the gearing" So let's say I need only 1 Nm , and the motor after the gearing is giving me...- Haim1404

Calculating eccentric bearing diameter for wave machine with spring return
Thanks Baluncore, I will think about it to. I fought that I will need bearing / gear 2 to be bigger then 1 so that the output torque will be smaller and more close to what I need (30 Nm), If the toruqe will be much bigger (300Nm as CWatters mentioned) will it not take out of control the...- Haim1404

Calculating eccentric bearing diameter for wave machine with spring return
kinda more like friction drive that slips, since the axis of bearing 1 is fixed, unlike normal cam that usually have spring.- Haim1404

Calculating eccentric bearing diameter for wave machine with spring return
Hi, Baluncore 1. yes, the eccentric direction in the picture is wrong. 2. When bearing 1 rotates 1/4 turn so is the first rod. Once it is released, the spring brings it back, and the wave start. So yes it is possible to say that most of the energy that goes into the wave step come from the...- Haim1404

Calculating eccentric bearing diameter for wave machine with spring return
Hello Guys, I'm building a vertical wave machine. I have a big bearing [2] (more like an eccentric) which is rotating by an electric motor with a constant speed of 0.359 rad/sec. When 3/4 of the bearing touches bearing [1] it supposed to rotate it a 1/4 turn, which as a result the ladder with...- Haim1404
