You have a 15 teeth, module 1 pinion. DIN 867 U2. x = 0 Dp = 15 Dext = 17 Df = 12.5 Db = 14.095 Alfa: 20º S1 = 1.571 With no more data I can't say you any more. Is very usual here in Europe.

Be careful with the gearbox efficiency. It will reduce the torque.

You are going to have lower consumption. Power = speed * torque then, your needed power, with less speed, is going to be lower. In DC motors, the amps needed are function of the power needed, then, if the power drops, the amps drops too. Be careful because the efficiency changes too.

CPosner, it is true that normally helical gears are less noisy than spur ones, but if they have similar correct design and manufacture. It could be so noisy an helical gear not very correctly designed or manufactured as a spur one with similar characteristics, and normally is easier to design or...

It is not so easy to see if an helical gear is going to have better or worst efficiency. Of course, you are going to lose energy by transmitting force to the bearings, but it is going to work smoothly. Normally, helical gears don't have so good efficiency as Spur gears, but it is not always like...

A worm gearbox efficiency is about 60%.

Be careful when choosing your dp. There is an optimus one. It is so bad to choose a tooth too small as to choose one too big. If you are going to use coarse gears, the surface endurance is going to be reduced because your effective contact surface is going to be smaller. Problems as pitting...

No, it is not HP or KW the units that you need to have to select the grease. You must know what is the pressure between the teeth (N/mm2). The other data you need is the tangential speed, to know the adherence needed. With this data, the Kluber technicians gave me the grease that we are using...

Ask to your oil supplier. Is the best person to answer you. Anyway, it is not needed to have very much oil or grease. Only the needed to guarrantie to have the correct film on the contact surfaces.

Try this: Output shaft torque: ratio x input torque x efficiency Efficiency in worm gearboxes is approximately 0.6 Then: 15 x 0,5 x 0.6 = 4,5 N·m

Normally, the profile modification has a very big influence in the gear strength. To have a 0.5 deplacement normally means to have approximately doble strngth than in a normal tooth because you are going to have a bigger base on the gear teeth but, (in gear modifications the most important word...

In this website you can find any screw and needed bore data. http://www.celofasteners.com/enwebcelofasteners/enproductoFasteners.html

Yes, I have used this control and it really works without any problem. Sorry because the problem in this case is the motor power (very high for the control) but the control is really for Single phase (little) motors, as yo can see in the page. You are talking about three phase motors...
