IEC and NEMA Motors

By Alex Malamos|2023-10-31T02:06:49-05:00July 11th, 2019|Application Examples|

IEC vs. NEMA Motors A large percentage of our customers produce their machinery for both the North American domestic market as well as for the various export markets of Europe, Asia, and South America. This often causes a design issue as power sources are different from market to market. Different motors should be specified to optimize the design, which then alters the gearboxes used with them. Most of our gear products have a solution for that complexity. Here is an example of one of those gearbox products when it came to IEC vs. NEMA [...]

This Customized Gearbox Saved Both Time and Money

By Alex Malamos|2022-06-07T12:19:53-05:00September 5th, 2018|Application Examples|

Many machine designers look to use standard components with the idea of saving time and money. But quite often a customized solution can do a better job of achieving both. We had a customer using a larger than necessary helical bevel speed reducer because of the requirement of a large output bore. They needed to drive a cooling drum in a plastic extrusion application. In addition to the driving torque, they had to feed a water line through the drum shaft journal to circulate water for the cooling process. To accommodate the water line a [...]

Baked Gearbox

By Alex Malamos|2023-04-17T17:42:07-05:00May 9th, 2018|Application Examples|

With Summer’s heat approaching, it’s time to discuss an extreme environment application. High-temperature engineering solutions are required in many industries. A customer recently came to us with an application for operating a painting fixture. The fixture was to hold aircraft parts for the U.S. Air Force. The basic design called for an inline helical speed reducer that would drive, what amounted to, a rotisserie device that would slowly rotate the part so that all surfaces were easily accessible. While it was relatively a straightforward application, there were some critical caveats. The first was a [...]

Torsion was the Culprit: Gearbox Problems and Solutions

By Alex Malamos|2024-01-03T01:11:23-06:00April 25th, 2018|Application Examples|

Backlash, torsion, and transmission error are all gearbox problems that can contribute to lost motion in a drive system that includes mechanical components. But this doesn’t mean you should eliminate these components, as the mechanical advantages of their use are significant. They just need to be monitored, analyzed and controlled. A customer came to us with a gearbox problem that looked to include lost motion as one of the symptoms. This customer produced a line of packaging assembly machines, one series of which put tops on containers. Their typical drive design wasn’t working on [...]

Outside The Box

By Alex Malamos|2022-03-17T12:14:05-05:00April 11th, 2018|Application Examples|

Have you ever had special gearbox applications where the standard catalog specs just didn’t fulfill the need? Perhaps you had to run too fast or had too much torque, or just not enough space for either? Catalog data is not always relevant. There are a lot of industrial and commercial gearbox applications, and even more in motion control, where comparing catalog performance data just doesn’t provide the correct solution. Why is this? Well, catalog data cannot be calculated for all the potential applications, duty cycles, speed, temperatures, and environments that a particular gearbox may [...]

Why do Replacement Gearboxes fail?

By Alex Malamos|2021-08-20T11:46:02-05:00January 22nd, 2018|Application Examples|

Have you ever replaced a failed gearbox, whether it just wore out after years of faithful service or it crashed and burned as the result of a major jam? Have you ever had said gearbox mysteriously fail again after only a day or a week or a month? Whether you are a user, a distributor who sold it to the user, or an OEM providing service to the user, the situation can be extremely frustrating. Unfortunately the reason for the failure probably wasn’t because of what you were thinking. We don’t get the calls [...]

Leaking Oil Investigation

By Alex Malamos|2023-06-21T13:03:59-05:00November 6th, 2017|Application Examples|

Gearbox seal leaks are the bane of gearbox users. Since lubrication is the lifeblood of enclosed drives, maintaining oil levels is critical to long life. When oil starts leaking, corrective action is necessary, but what action? What’s going wrong? Actually, the answers can be varied as the gear type used, how it’s mounted, the speed it’s running, and the environment it’s in. We had a user of a competitive worm gear speed reducer give us a call. He had his gearbox mounted with the output shaft horizontal and his quill-mounted motor pointing vertically, below [...]

DieQua Maintenance Tips

By Alex Malamos|2022-03-03T19:40:04-06:00September 15th, 2017|Educational|

Maintenance Tips and Mistakes to Avoid DieQua offers tips for installing, operating, and maintaining gearboxes. Below, we discuss common gearbox maintenance mistakes and how to avoid them. Specifically, our tips include both the error and the preventative measures in each of these scenarios so you can best learn how to maintain a gearbox. Tip 7 - Correctly Mount Servo Gearhead Mounting the gearhead horizontally is incorrect, as it allows for the increasing of some loads associated with lateral misalignment in this orientation, which shortens the life of [...]
