![]() ![]() If you buy a NORD Parallel Gear Unit, you will have little difficulty in adapting it to your application. Our MAXXDRIVE® Industrial Helical Gear Units: Maximum flexibility Users have many options for the installation of output flanges (B14 flange as standard). The helical gear units can be combined with all electric motors from the NORD range. Large roller bearings and precise alignment of shafts and gear wheels ensure a long service life for the gear units. MAXXDRIVE® Industrial Gear Units with helical gears are ideal for heavy duty applications due to their high torques. What are the advantages of MAXXDRIVE® Parallel Gear Units? The Helical Gear Units can therefore easily withstand the harsh conditions of use on the conveyor belt. Thanks to their integration into the tried-and-tested UNICASE housing, the gear units also have high axial and radial load capacities. For example, this was the case in a Moroccan phosphate mine: Here, phosphate ore with a weight of several hundred tons was to be transported for further processing via a two kilometre long conveyor belt.įor the belt drive, the customer decided on NORD MAXXDRIVE® Parallel Gear Units because these offer output torques of up to 282,000 Nm and powers of up to 6,000 kW. Our MAXXDRIVE® Parallel Gear Units are used wherever high torques are required.

You can then take the over-pins dimension to generate a sketch making the pin tangent to the flank, mirror the involute using a plane through the centre of the pin, and then use another sketch to create the root fillet tangent to the root diameter. I've found that the simplest and most flexible method for spur gears is to use an equation-driven curve to generate a single involute, which requires just the base circle diameter. Having said that, there have been a few occasions where I've wanted an accurate model to run FEA on. #Helical gear design in pro e software#Gear calculation is best done by purpose-written software (such as Ricardo SABR-GEAR: ). Most of our gear models just have an arc to represent the flanks - it looks good enough, is easy to model and regenerates quickly. Ground threads, for instance, also creates a different profile than one would think.Īs a gearbox/transmission designer, I agree with Elvind that for most purposes it's not necessary to model the teeth accurately, as the form is generated by the cutting machines, and they take the gear data in parametric form in any case. For instance, the involute of a gear tooth is actually the result of the manufacturing process but we have to work hard to define it. It makes a difference if you just sweep flat sections in many cases. I have not seen anything in Creo that does an accurate representation of "round" cutting tools. They will help but do not count on them for being "gospel".Īlso be very careful if you do need precise gears. #Helical gear design in pro e download#They have some download models in Pro/E format that are generated on the fly. I really like the handbooks provided by SDP-SI. Not to the level of power transmission, but at least the basics of gear design and manufacturing. ![]() Most gear manufacturers have excellent data available. What will you be doing with your models? Will they be passed to manufacturing? Are you doing analysis with them? Or are they simply a placeholder for getting a good model of a transmission? ![]()
