motion control - hybrid radial bearings

E. Longmeadow, MA – — Motion Control – CeramicSpeed Insulated ball bearings are custom made for electrical motors and your guarantee against damage caused by stray currents.

The ceramic balls used for this product series are non-conductive and have an insulating ability of 15 kV per mm – higher than that of atmospheric air.

Bearings from competing manufacturers with an insulating coating typically have an insulating ability of up to 1 kV; provided that the coating is not damaged – for example when the bearing is mounted. In practice this protection isn’t always sufficient, meaning that these bearings are also vulnerable to damage by stray currents.

In addition to being protected from the passage of electrical currents, the operating temperature is 10-20 °C lower, and the resulting is a bearing life typically 4-8 times longer than traditional steel bearings.

motion control - lm76

 

E. Longmeadow, MA – — Motion Control – Application  – Dairy machinery manufacturers are under intense scrutiny by FDA inspectors when it comes to FDA material and caustic washdown compliance. Recently, LM76 was called by a large US dairy packaging company to review a problematic portion of their filling line. After each shift, the filling line is washed-down, has a caustic foaming agent applied to kill bacteria and then is final rinsed. The caustic foaming agent was destroying – literally eating – the aluminum shaft supports while shafting exhibited pitting and showed signs of minor corrosion. Additionally, there were areas where product got trapped and these locations were havens for bacterial growth. Because this system was in-place and our customer was the end-user, LM76 engineers had to use direct drop-in replacement com¬ponents. What to do?

Motion Control -What To Consider When Specifying A Linear Slide

Motion Control – Tutorial

Considerations when specifying a linear slide for a new or existing application.

By Mike Quinn • LM76

When a design engineer has fully defined a linear-motion application’s requirements regarding travel length, speed, force, and accuracy as well as repeatability, the next question to answer is this:

Does an off-the-shelf linear slide (or a stock linear slide from a catalog) fully satisfy the application?

motion control - lm76

Off-the-shelf linear slides are advantageous for their quick delivery and lower cost than that of custom components. No wonder most linear-motion designs do in fact employ off-the-shelf linear slides from various component and system suppliers.

Easily …   … Using Custom made LM76 Jet Rail Bearings and Shafting!

When a privately funded research company was ready to move from their original Proof of Concept to a sustainable fusion reactor to produce clean sustainable energy, they realized that extremely heavy components would need to be assembled and disassembled and reassembled again for design modifications and maintenance. The completed assembly would be the length of two buses and easy alignment of the individual components would be critical.

Linear Motion Application – How Do You Move Articles of Antiquity?

Very Carefully With A High Load Rail System from LM76!

motion control - linear guides

E. Longmeadow, MA – — The Boston Museum of Fine Arts (MFA) has to move articles of antiquity from one location to another. In this instance, they are moving a 5000 year old relief (hieroglyphics) weighing 8000 pounds to a new location in the Museum. Here is a frontal photo of the Relief from The Tomb of Senenuka.

Part of wall from tomb of Senenuka; nine stones fitting together and including two niches; lower left piece smooth limestone; upper far left preliminary black ink sketch; right of this sketch is a complete relief showing two seated figures; central piece has large scene of seated male on the left and other smaller male figure to the right; upper far right male figure relief outline; left of this again a scene of two seated figures at a table.

motion control - linear bearings

Senenuka Time of Khufu or Khafre (Maybe Dyn 5?) Overseer of the Pyramid-town of Khufu, Director of King’s wad-priests, Boundary official of a settlement, etc.

The MFA contracted CBI Consulting of Boston to design the frame and fixturing. Craig Barnes, an award winning architectural engineer called Mike Quinn of LM76 to review the linear motion application. Over the course of several weeks, LM76 and design partner Todd Kanipe designed a telescoping, high load roller/linear motion rail system that won approval. According to CBI’s Keith Bouchard, the linear rail system moves very smoothly and so far meets the expectations of this program.”

Linear Motion Application – According to MFA Antiquity Specialist Jean Louis Lachevere, “All of these moves present very real dangers to the artifact being transported. In this case, we have a 8000 pound relief which already has its problems due to age and the fact that it is limestone ( limestone is very vulnerable to the atmosphere ).” Seen from the front, the relief is straight. From the back, much of the top back is gone. Thus, the back of the relief has to be plastered so the back is flat. Pins are inserted to further reinforce the relief and then it is tipped on its back. It is then moved to its new atmospherically controlled display case. LM76’s design is used in the transfer from the dolly to the mounting rails and restraints in the display case. This 36” motion is fraught with things that can go wrong. One of the considerations is the possibility of an earthquake…any problem conceivable is taken into account.
