Motion Control – Zero-Backlash Servo Rotary Indexing Table!

May 22nd, 2018

Editor-Publisher

Electromate offers Zero Backlash Rotaru from Sankyo

Vaughan, Ontario, Canada — Motion Control Components — The Sankyo Automation RollerDrive® Reducer is a precision gear reducer that uses a zero backlash roller gear mechanism. The unit is constructed from an input shaft and a turret (output shaft) that is assembled with roller followers. The roller followers are preloaded against a screw-like input shaft to eliminate backlash.

Sankyo servo indexing tables offer a constant lead cam with a servo motor drive for programmable motion. Sankyo servo indexing tables provide fast highly accurate motion, with the added capability to move medium to heavy loads. The preloaded cam & turret provides a high performance zero-backlash servo indexing table for all your automation needs.

The RU Series servo indexing table is available in 11 different sizes. These servo indexing tables come with varying ratios to maximize the motor’s torque capacity, speed requirements and enhance the overall accuracy. Special applications may require double reduction ratio of the internal cam and an additional reducer to provide large torque capacities or slower speed.

Features include:

Zero-Backlash -The RollerDrive uses a unique preloaded mechanism to completely eliminate backlash and deliver output motions that are faithfully true to input commands
Second Reducer Option -Multiple reducer options keep the servo at optimal RPM speed
Rigidity Suitable for Machining Applications -An exclusive ouput turret bearing and cast-iron housing toleratres heavy vibrations associated with machine tool applications
Versatile for Retooling -RU Series can keep pace with the ever-changing tooling requirements
Short settling times – The RollerDrive provides fast highly accurate dynamic motion

Motion Control – Steinmeyer Tutorial – Ball Screws – Maximum Load!

May 7th, 2018

Editor-Publisher

Motion Control Components - Steinmeyer Cooled Ball Screws

Tutorial presented by Steinmeyer – Their Ball Screws are specially manufactured for dynamic performance

BURLINGTON, MA –Motion Control Tutorial – Ball Screws – Maximum Load

There are five ways a ball screw may fail due to overload:

Excessive dynamic loading, which means the screw makes too many revolutions under a certain load resulting in material fatigue. This can be avoided by selecting a ball screw with sufficient dynamic load capacity (or by reducing the number of revolutions and/or reducing the load). This is the subject of the load capacity discussion.
Exceeding the static load capacity, which causes instant and permanent damage to the ball screw due to brinelling of balls and races, and prevents any further normal operation of the ball screw. Static load capacities are listed as technical data.
Buckling of the shaft under compressive load. Buckling load value depends on bearing method and free length of the loaded ball screw shaft.
Failure of the nut body or of the bolts that connect it to the slide. This may happen even before the static capacity is reached. Safe loads are discussed on the following pages.
Radial loads. It means the load capacities given in this catalogue apply only to pure axial loading. As there are always tolerances in the alignment of bearings and linear guideways, there may be a small amount of radial force, which should be minimized. Under normal conditions, a radial load less than 5% of the minimum axial load will not cause any problems. When considering a ball screw for use under radial load, please consult Steinmeyer engineers.

BUCKLING

There are several analytical ways to demonstrate safety from buckling. In machine design, the most frequently used is a simple calculation using formulas based on Euler equations.

Other, more accurate methods include non-linear FEM analysis and more involved mathematics. These methods are normally used in aerospace applications, where excess safety margins are not possible due to weight limitations. Please contact us if you require such an analysis.

Please CLICK HERE for a simple form of buckling analysis. Buckling

FRACTURE LOAD

Some ball screws cannot be loaded all the way to their static capacity. Screws with high dynamic load capacity (which might be selected to obtain a long enough service life at a much lighter load) will necessarily have a high static capacity. But the term “static capacity” is misleading, since the ball screw may actually fail due to fracture of the nut flange, nut body, or connecting bolts before reaching this load!

Please CLICK HERE for the maximum safe loads. Fracture Load

TECHNICAL TIP

A reasonable load for a ballscrew, which may be sustained for significant travel, is about 10% of its dynamic capacity.

A mean load of 10% of its dynamic capacity results in a theoretical life of 1 billion revolutions, which is the upper limit of the range where the life equation is valid. Mean loads of a reasonably sized ball screw will therefore be somewhat higher than this, but normally not exceed 20% of its dynamic capacity.

For short peak loads, the loading may be higher, but normally the loading of a ball nut with 2-point contact should not exceed 2.8 times the preload. And preload is around 5% – 10% of dynamic capacity.

As a rule of thumb, this all means the load range for a ball screw, to be used in a machine tool application, is really about 10% to 30% of its dynamic capacity. However Steinmeyer ball screws are used in many applications as force actuators where the loading is up to 100% of dynamic capacity but with low speed and acceleration. For example, they may be used to power injection molding machines, where high forces occur at reduced speed. Please consult our engineers for details.

Editor-Publisher

Motion Control – Linear Motion – LM76 FluidLine Motion Control Linear/Rotary bearings are FDA/USDA & 3A Dairy Complaint. They are also caustic wash down inert. FluidLine bearings one piece construction has benefits over traditional Teflon Composite lined aluminum bearings: if you have a wear situation, Teflon Composite Bearings have a .035″ Teflon Composite Liner. Once you wear through the liner, you are into the aluminum shell. FluidLine bearings will simply wear more and more until they are too sloppy and can replaced at your convenience. They are also less expensive in volume because there are fewer manufacturing operations. We can easily design and produce special ID’s, OD’s, Lengths and features such as flanges.

Is Your Workplace Safe? Find out with the safety Gotcha Stick!

April 17th, 2018

Editor-Publisher

STI — Omron introduces the safety Gotcha Stick Safe Distance Scale. This three-segment safe distance stick accurately tests the allowable barrier opening size based on the distance from the point of operation. It features English measurements on one side, and Metric measurements on the other.

Although not officially adopted by OSHA, the safety “Gotcha Stick” is based on data from “A Review of Machine-Guarding Recommendations,” by Donald R. Vaillancourt and Stover H. Snook of the Liberty Mutual Research Center for Health & Safety. This data redefines the dimensions of the human arm for the purposes of machine guarding. The resulting new stick has been modified to include openings of less than 1/4 inch over the first 1/2 inch distance.

Guarding machinery by means of hard (fixed) barriers is one of the main ways of protecting personnel from point-of-operation hazards. The safety “Gotcha Stick” is the easiest means of verifying that openings in hard guarding will not allow the point-of-operation to be accessed by the operator.

With headquarters in the heart of Silicon Valley, STI was founded nearly 30 years ago and employs more than 350 people. STI has been selected twice by Forbes and three times by Business Week as one of the “world’s best small companies.” STI’s safety products are used to protect workers around machinery, automated equipment and industrial robots. Their products serve a wide variety of applications and markets, including semiconductor, automotive, electronics manufacturing, packaging and consumer markets.
