How to find the overhung load of belt mechanism
How to find the overhung load of belt mechanism
(OP)
Hello folks, this my first post here. Im electrical eng. but I have to do some mechanical staff and here starts the problems. I have to choose gear box. In most catalog there is overhung load value. In my machine the I use belt to transfer the power but im not so sure haw to calculate the max overhung load. By def the overhung load it that load that acting then use belt, chain , rope and so on. And its equal of the moment on radios of mounted element F = M/r. we have additional const “z” with depend of number of teeth, tension of belt and so on. Im going to use SEW geared motor, so they give overhung load action on angle “a” in the middle point of output shaft
.
Here is schematic of my machine
.
The output end of shaft in couplet with pulley. So my question is there the overhang force is acting and on what angle. I need to know it, to choose the right gear unit. Thanks in advance !

If your pulley is supported by bearings, the side load is insignificant.
If those two triangles on either side of your pulley are not bearings supporting it, your coupler will be working (somehow) at a 90° angle, and the side load on your gearbox will be the least of your worries.

The actual side loading of the gearbox output shaft will depend on how well everything is aligned, and what type of coupler is used.

The manufacturer's concern about overhung load on a gearbox has nothing to do with the strength of the shaft. He is concerned about overloading the bearings inside the gearbox.
