Wash Down Clutch With a Lead Time That Saved The Day

clock February 11, 2016 06:35 by author Mach III Clutch

C5A3K-001A food processing equipment manufacturer received an unexpected and unpleasant piece of news when they tried to purchase the nickel plated jaw tooth clutch they had designed into a new machine, a 16 week lead time!  Needing a 5 week lead time to meet the delivery date required by their customer, the manufacturer contacted us.  Did Mach III have a clutch that was equivalent?  Could we deliver in 5 weeks?  After reviewing the application and coordinating with production, our engineering team said, "Yes."

Our designers even found a way to expedite installation by incorporating an adapter so the clutch could be directly connected to the Lovejoy L150 elastomeric spider coupling used in the machine design.

The base for this design is the C5A2K-STH catalog model. For corrosion resistance, the unit is sealed and all exposed components are made from stainless steel and aluminum. This clutch is a prime example of the quick customization available from Mach III.

Holding Brake Connects Directly To Rotary Actuator

clock June 29, 2015 17:59 by author Mach III Clutch

Mach III Holding BrakeLike many of Mach III’s custom designs, this brake design began with an inquiry about a catalog model spring engaged brake.  An engineer working on a drive system needed a holding brake to prevent a Rexroth RAK-8D  actuator from being back driven and losing position if air pressure was lost. The connection to the actuator was a 19mm square rather than a typical round shaft and key and, since the system would be on an offshore oil drilling platform, the brake had to be enclosed.

While it was possible to enclose the D4F3R-STH brake the engineer had inquired about and produce it with a square input, he would have to make changes to his design to connect the brake to the motor. Instead, Mach III engineers presented the concept of this enclosed spring engaged, air released brake with a flange containing six through holes on an 80mm bolt circle to connect directly to the actuator. The brake has 500 pound inches of torque and requires 77 PSI to release.  The time span between the initial inquiry and the quotation for the custom design was just 4 days. The lead time to produce this
completely custom brake solution was only 3 short weeks.

Mach III Shaft Connection Options

Mach III will modify its catalog model friction clutches, brakes and torque limiters or create an original design that connects to the shaft the way you prefer. Pictured are a few examples, clockwise from top left:

  • Traditional bore and keyway with set screw. Available in both Imperial and Metric sizes with standard or non-standard keyways.
  • Broached for a square shaft
  • Extended hub with bore and keyway, slotted for connection to the shaft with clamp collar
  • Extended hub with bore and shrink disc

Custom Design Solutions: Clutch with Spider Coupling Adapter

clock July 22, 2014 12:37 by author Mach III Clutch

This clutch is similar to the  58SI  SensiFlex® shaft input tension control clutch.  It has been modified to include a pilot mounted coupling hub which mates with a spider coupling (a.k.a.  jaw coupling).  This clutch is drop-in ready to simplify installation.spider-coupling illustration

Would a custom design make your assembly process easier?  Mach III supplies custom adapters and couplings for many catalog models. 




Brake with Air Released Coupling Simplifies Process

clock July 3, 2013 02:22 by author Mach III Clutch

Brake with Air Released CouplingAn air engaged friction brake and air released coupling are combined in this custom designed assembly.  The brake stops and holds a roll of material during a laminating process. When the process is complete, the user applies air to the coupling which then slides open. The roll, joined to the coupling with a tang-end shaft, can then be quickly removed. 

The air released coupling is also available as a stand-alone item.  



Sealed Clutch With Output Flange For Heavy Wash Down

clock March 11, 2013 14:58 by author Mach III Clutch

A pair of these clutches drive vertically mounted brushes which scrub the sides of a vehicle in an automatic car wash. This clutch had to fill two requirements: (1) operate in an environment where exposure to both water and detergent is constant and (2) support the brush assembly. Mach III Sealed Clutch with Custom Output Flange Below are the special features incorporated into this design:

  • Enclosed, sealed aluminum housing
  • Grease packed under top oil seal and inside the flange housing to prevent water seepage
  • Port in housing for vent tube.  Ventilation prevents the clutch from acting as a pump and drawing water into itself during disengagement.
  • Custom output flange

Custom Air Released Coupling Facilitates Quick Roll Change

clock December 13, 2012 15:07 by author Mach III Clutch

COUPL-020 CLOSED (3)

This air released coupling was custom designed for an application requiring a quick and simple means of inserting and removing rolls of material.  The face of the coupling (right) bolts to the machine frame.  Air is applied to the coupling when the operator presses a button which retracts the sleeve and exposes the slotted shaft end.  The operator can then slide a tanged shaft into the coupling.  When the air is released, the coupling sleeve closes to retain the shaft. 

The shaft is driven by a clutch which is connected to the extended shaft shown on the left side of the coupling. This coupling can be used with a clutch for stop/start or tensioning applications or a brake for stopping, holding or tensioning applications

 

 

 

 

 



Custom Design Solutions: Clutch with Undersized Pulley

clock June 28, 2012 17:31 by author Mach III Clutch

For a laminating machine, the customer required Mach III’s catalog model 58PI SensiFlex tension control clutch. However, the machine design called for a 44 tooth, 5M belt pulley that was too small in diameter to 58PI--ADPTR-020-WEB5fit on the clutch’s 2.75 inch diameter pilot. The solution to this dilemma is a custom adapter including a P44-5M-25 pulley that bolts to the 58PI pilot. The set screws which fix the clutch to the shaft are accessed through a hole in the adapter.

Mach III has the capability to supply custom adapters and couplings for many catalog models.



Custom Design Solutions: Special C-Face Mounting

clock June 8, 2012 11:57 by author Mach III Clutch

C3C2P-001Mach III designs and manufactures clutches, brakes and torque limiters in custom c-face configurations.  In this example, the customer needed a device to limit the torque between the motor and a coupling which was used to fasten a cap.  The customer required the torque setting to be adjustable.

Mach III suggested an air engaged clutch.  The customer would be able to adjust the torque applied to the capper coupling by increasing or decreasing the air pressure supplied C3C2P-001 001to the clutch.  When the capper met resistance, the clutch would slip.

Unique in this application was the motor face which required that the clutch mounting flanges be off-center from the clutch housing.  The motor and capper coupling were sent to Mach III so the dimensions could be verified.  The second photograph shows the finished clutch in place between the motor and capper coupling.
