Supporting the World’s Leading Injection Molding Technologies

Injection molding machines are used to manufacture structural foam products from precision to large parts.  Japanese injection molding machines enjoy a worldwide reputation for their precision and have gained a 40% market share of the international market.  Traditionally, injection molding machines were mainly of the hydraulic type but in light of recent concerns for the environment the motorized type is increasingly popular as they are cleaner and quieter.  Belts are used in the motorized type for injecting and clamping parts.  For these applications Mitsuboshi Belting has chosen to use a special hard rubber that has high strength and durability and generates a transmission volume that is twice as large as the conventional S8M and S14M.  Mitsuboshi Belting also achieved higher transmission efficiency and lower noise with its products, receiving high acclaim from many of the injection molding machine manufacturers.

It’s now been a week ……

….And I’m very pleased with the results of our new Website at Bearings Incorporated .

Come  on .. let’s take a tour …

Not only can you purchase bearings, with our stock being revealed more and more on a constant basis; you can read up on our history, you can check out our manufacturers, with links to some and more to come.  Stop in and check out our testimonials to see what our customers really think of us. 

Currently our site only takes Paypal or Credit card, but we have plans for the future of adding open account as an option (with prior approval of course).  To find forms for entertaining the idea of opening an account with us, check out our Forms page.  You can also use this page, if you reside in the state of Wisconsin; and are tax exempt, a few clicks, and you have a valid Tax certificate for filling out and forwarding  to us. 

And of course, our contact us page in which you can inquire about purchasing our products.  Just because it may not be listed doesn’t mean that we can’t get it.  We will be changing the on line stock items on a regular basis, and it will take time for us to upload all of the available vendors we have. 

And then last but not least — the blog connection .. which completes our circle, as it will attach directly back to here.

Sign in for making a purchase, and with that purchase you can enter the coupon code of BRGS into the coupon box, while checking out, and save 10% off of all products.  This coupon code is in effect until March 15, 2011.

I must apologize however, as we are set up to do business only within the 48 US continental states.  We do not export outside of this parameter. 

Let’s make our second week even better!

Thank  you again for your present and future patronage!

Baldor – Maska –Elastomeric Couplings; Selection and Maintenance Tips

Thursday, February 10th, 2011

Advances in technology and design innovation have resulted in numerous benefit of Elastomeric Couplings in a vast array of applications.

Elastomeric Couplings

Selection and Maintenance Tips

Flexible Coupling:  A mechanical fastening devise used to connect two rotating shafts for power transmission that accommodates equipment misalignment.

Elastomer:  Resilient material having elastic properties.  (rubber, synthetic rubber or plastics)

Elastomer Element:  An assembly of components designed to connect axially oriented shafts in order to provide power transmission and accommodate shaft misalignment through elastomeric materials.

Why Elastomeric Element Couplings (versus Gear-type)?

ENVIRONMENTAL IMPACT – No lubrication required.  For every dollar spent on grease, 5 times more is spent on environmental cleanup.

PERFORMANCE – Elastomer elements are resilient and reduce the amount of vibration and shock being transmitted.  In rare events when the element does fail (extreme torque or excessive misalignment), a new insert is installed in minutes.

OUTPUT – Handle equal or higher torque requirements compared to gear couplings without increasing the size of the part.

COST SAVINGS – There is no metal-to-metal contact as power is transmitted through non-metallic elements; this reduces the replacement component to just the element.

OPERATIONS – Coupling advantages result in reliable, clean operations and improved preventive maintenance which contribute to reduced failures and equipment downtime.

MAINTENANCE – Multiple cover options allow for easy inspection and as it is not necessary to move the parts, change-out takes only minutes.

Importance of Proper Selection

Coupling two shafts together can require detailed calculation.  The best suited coupling type will depend on the application, drive and driven equipment, shaft diameter, space available, power, torque and speed to be transmitted, life expectancy required, electrical insulation, operating temperature range and the nature of the misalignment — which  could be angular, parallel or a combination.  Different coupling types are also differentiated by torsional, angular, radial and axial stiffness.

What you should know about coupling selection, and why!

  1. Horsepower — almost all couplings are sized based on the horsepower to be transmitted.
  2. Type of Drive — if the power source is a reciprocating engine, there will usually be a “Driver Service Factor Adder”.  Torsional vibration is produced in a continuous steady form that can be transmitted directly  into the driven machine; an elastomeric coupling is designed to help dampen this vibration.
  3. Type of Driven Equipment — driven machines are classified based on their load characteristics and a service factor is assigned accordingly.  Multiplication of the service factor by the input horsepower gives the design horsepower upon which most couplings are sized.
  4. Speed at which Couplings Operate — Most selections are based on the HP at a certain RPM.  As the speed is reduced, the torque increases.  Verify that you don’t exceed the maximum speed of the coupling.
  5. Shaft Sizes — Make sure the selected coupling fits with the required bore.  You may have to choose a larger coupling than your design calls for in order to obtain the correct bore size.
  6. Space Limitations — Will the couplings length and diameter fit within the allotted space?
  7. Environment — Several factors that occur in the surroundings can affect the service life of a coupling.  For example, the operating characteristics of an elastomeric coupling can change if the temperature exceeds 170 degrees F (77 degrees C) or is -30 degrees F (-34 degrees C); and if the environment is wet or oily, some types of couplings are inappropriate.

Data required …

  • Power in HP, CV or KW
  • RPM
  • Shaft Diameters (driven and drive shafts)
  • Service Factor

Pro Active Maintenance

Keeping machinery operating successfully requires careful design selection, proper installation, periodical inspection, observing changes n performance and investigating thoroughly the cause of a failure.

Tips:

  • Does the coupling show signs of distress.  Such as running hot, loose bolts, cracked rubber or power on the baseplate?
  • Is there excessive backlash across the part?
  • Does the shaft rotate easily and consistently through a 360 degree rotation? Or, does it bind at some point?
  • As you disassemble, are any parts missing?  Is there excessive wear?  Compare the appearance with a new coupling.
  • Is the element worn or cracked?  Are the set screws still in place or were they loose?  If the element is excessively worn, was the total time it was in operations compatible with its service life?
  • When replacing an element, use an appropriate puller to remove the flanges.  Do not force then off with a hammer.
