Parker Gearheads and Lost Motion

October 5, 2012

Innovative-IDM features Parker gearhead from Parker EMS. Parker is a big company with decades of experience in motion and gears. I found this tidbit about “lost motion” in gears on the Parker Electromechanical Blog. In addition to Parker, Innovative-IDM also carries Wittenstein (formerly Alpha Gears) gearheads as well.

Lost motion contributes to position error, can complicate control efforts, and can introduce magnified dynamic loading on components. Many reduction technologies try to minimize lost motion and its effects.  When evaluating various reduction technologies it is usually not sufficient to consider only backlash, but rather all of the lost motion contributors which would include the torsional stiffness of the gearhead.

For a pair of meshed gears, backlash is the amount by which a tooth space exceeds the thickness of an engaging tooth.  For a gearhead, backlash is the amount of motion the meshed gears have when the input is held fixed.  Torsional stiffness on the other hand may include such things as deflection of components, bearing support, etc.

Theoretically, perfect gears do not require backlash to operate satisfactorily.  However, manufacturing tolerances, bearing dimensions, thermal considerations, and other practical considerations result in unavoidable backlash.

At Parker we measure the backlash of every Stealth gearhead by locking the input and applying to the output a torque of 2% of the gearheads rated torque.  Measurements are taken at 6 points around an output revolution to ensure constant, low backlash throughout the entire cycle.  Torsional stiffness is maximized with our high tooth to tooth contact ratio, and integral ring gear machined directly into the steel housing.  The combination provides a well balanced product that will minimize the lost motion of any application.

What Do I-IDM Houston and Wittenstein Have in Common?

August 22, 2012

A new RaceWay gas station and convenience store recently opened in a shared parking lot with our Houston office. One of the perks of the construction was a new “retaining pool” behind the RaceWay. I couldn’t help but think of the resemblance between Innovative-IDM Houston (middle photo) and Wittenstein’s US HQ in Bartlett, Ill. (Top photo). I guess the main difference is there is water in Wittenstein’s pond. And without water, I guess our pond is really just a ditch.

The dramatic photo at the bottom shows thirsty Innovative-IDM employees stampeding the RaceWay on opening day. That’s Houston operations manager Charles Manning with the nonchalant look of hands in pockets as he sashays toward the door, trying not to draw attention to himself. But don’t let that conservative approach fool you; seconds later, he had recklessly squandered $1.49 of his family’s savings on a Crush drink.

Optimizing Delta Robots with the alpha TP+

From Out of the North Comes a 20-year-old Alpha Gearbox

Wittenstein Gearbox Still Turning After 20 Years

The alpha gearbox had been turning equipment for 20 years, but it was time for an upgrade.

Wittenstein’s systems integrators received a call from a customer asking about updating the gearboxes on their machines. The customer, from Canada, purchased the new alpha SP+ and sent in the old gearboxes to its distributor.Upon further inspection, the gearbox was one of the original Wittenstein products…and in remarkable condition, according to Wittenstein. The gearbox (pictured left) had been turning machines for nearly 20 years with precision in motion.

Wittenstein is looking for other old gearboxes that still are turning. What’s your story? Send it to info@wittenstein-us.com
Innovative Automation can help you with any of your gearbox applications using alpha/Wittenstein gearboxes. Call us at 877.906.2100 or email info@iacorp.om for prompt assistance.

Launch of New Electronic Look for Wittenstein Site

July 16, 2009

Wittenstein recently unveiled a new look Web site to improve functionality with customers. A recent upgrade includes a part number generator through the product selector tool. Here, for instance, you can virtually spec out which alpha gearbox you will need for your application.

The latest upgrade to Wittenstein’s Product Selector tool allows users to view and modify automatically created part numbers for specified products. The alpha gearbox products are currently in the Product Selector and requesting CAD files and creating part numbers takes only a few clicks.

Access to the Product Selector tool tool is through the specific product pages and also by clicking on “Product Selector (CAD)” at the top of all Wittenstein website pages. Further updates for this tool include adding alpha CP (alphira) gearboxes, V-drive products, Couplings, Rack and actuators.

You can check out all of the virtual engineering features of the new Wittenstein Web site here. How can we help you with Wittenstein products? Call 877.906.2100 or email info@iacorp.com  for immediate assistance and LEGENDARY customer service.

SMC HQ

June 11, 2009

smcHQHere’s another photo of one of our channel partner’s US headquarters. SMC is headquartered in suburban Indianapolis. It doesn’t have a lake like Wittenstein or WAGO, but it looks pretty nice. Hope we can visit sometime later this year, and also revisit Omron and the new location of Yaskawa VFD sales as well.
