Low-backlash gearboxes, racks and pinions

Newsarchive


Calculate a rack and pinion drive, how do you do that? If you immerse yourself in this you will be confused with terms and formulas that make the situation very complex. That is why we try to explain to you in this article how you can do such calculation the easiest. An important principle is that you realize that the calculation and selection (rack, pinion, gearbox and motor) is done by trial-and-error: you have a good chance that you have to do the calculations again with other parameters, such as the diameter of the pinion or the quality (read in this case: hardness) of the rack.

What millennial-old technique is the basics of many of the most innovative technical breakthroughs of this moment? Robotics, 3D printing and new means of transport all have one thing in common: often they are driven by a planetary gearbox. As a supplier of planetary gearboxes, of course we know all ins and outs, but what if you encounter this technique for the first time? We have decided to explain it clearly for all - In this article we discuss the basics of the planetary gearbox.

Vestel, a major technology company from Turkey, had a special application for our partner Koot Automation & Service B.V.: 28 rotating video screens as part of an exhibition marketing concept. Koot Automation & Service deal with similar technical challenges but on this occasion did not succeed with the gearboxes available due to the desired accuracy. Apex Dynamics could solve this issue with their compact and accurate PD gearbox. And on top of that, these 28 planetary gearboxes are available within 2 weeks. The end result (see video below this message) is one to be very proud of.

Apex Dynamics BV sponsors the 21 students who participate in the Bridgestone World Solar Challenge on behalf of the University of Leuven as the team Punch Power Train Solar Team. The engineering students have worked for 13 months to get the Punch 2 ready to start on the 8th of October for the 3,000 km long journey from Darwin to Adelaide. The Punch 2 will prove itself in an enormously competitive playing field of more than 50 teams. Everyone tries to drive the route as fast as possible!

The food processing industry naturally has solid hygiene requirements and this is also mandatory for gearboxes. The requirements vary by country and location in food processing but the most important factors are choice of materials, aseptic conditions and not at least the lubricant. The latter is often overlooked, but this is an essential element. The American USNSF developed a well-accepted and approved standard (H1 through H3), but an ISO certification has also been added. In this article we discuss both.

Corrosion resistance is critical in, for example, the food industry, offshore and in cleanrooms. Rust has adverse effects on the accuracy, the noise level or the life span and must be avoided at all times in applications in such kind of environments. Apex Dynamics also has a stainless steel rack, but this is not always optimal in terms of strength and accuracy. The racks of Apex Dynamics can therefore be manufactured with an extra - all sides! - corrosion protection.
