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.

Servo Motor Brake Holds When Power Is Off

clock November 10, 2015 20:30 by author Mach III Clutch

Servo Motor BrakeThis spring engaged, air released friction brake was designed at the request of a thermoforming machinery manufacturer in Taiwan who needed to assure that a forming platen is held stationary in the absence of air pressure.  Communicating by email across 7,800 miles and 12 time zones, Mach III’s engineers were able to obtain all the details about the application as well as the dimensions of the servo motor and gearbox the brake would go between.

Within a couple of days a design and quotation were presented for this holding brake which has 2,409 pound inches of torque.  The brake connects directly to a Yaskawa SGMGV-IE 15kw servo motor on the input side and a Lenze GKS-11 3W gearbox on the output side.

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.

213TC to 182TC NEMA Frame Brake

clock July 25, 2014 03:24 by author Mach III Clutch

What makes this Mach III brake custom?  Not much, really.  It is basically a catalog model D5C3R-21H spring applied brake with an output shaft diameter of 1.125 Inch instead of 1.375.  A minor change, but when the brake must be mounted between a 213TC NEMA frame motor and a 182TC NEMA frame gear box it is a major difference.  No longer does the client have to purchase a brake, disassemble it, turn down the output shaft and put it back together.  This Mach III brake is out of the box and on the machine with a lead time of only 3 weeks.

High Torque Holding Brake Fits Within Diameter Restriction

clock November 1, 2013 07:05 by author Mach III Clutch

D6F4G-003_x500The application for this spring actuated holding brake required a minimum 3,300 lb-in torque capacity.  Our engineers first recommended the Mach III catalog D8F3K-STH,  however, the machine design could not accommodate the 11.75 inch flange diameter of this standard model.

To accomodate the radial space constriction, Mach III used the D6F3G-STH brake as a base and incorporated additional friction surfaces. The result was a brake with 4,405 pound inches of holding torque within a 9.53 inch diameter.

Clutch-Brakes for Harsh Environments: Mach III Has It Covered

clock October 5, 2013 07:45 by author Mach III Clutch

W4A2H-STH_W4A2H-004Mach III frequently adapts catalog products to meet the individual needs of the application.  In this example the customer required a combination clutch-brake that would drive a pilot mounted sprocket when engaged and hold it stationary when disengaged.  However, the environment in which the clutch-brake would operate was dusty and there was a potential for particulates to enter the clutch-brake where they could cause premature wear or failure. 

Mach III adapted the cylinder portion of a catalog model W4A2H-STH clutch-brake by expanding the outer diameter and elongating it to form a cover.  Both the catalog model and modified design are shown on the right. 

This or a similar solution can also be used in clutch, brake and torque limiter designs.

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.



Custom Design Solutions: Pilot Mounted Sheaves

clock June 4, 2012 12:33 by author Mach III Clutch

Friction clutches from Mach III Clutch, Inc. can be shipped complete with a pilot mounted sheave. In some cases, the sheave is manufactured by Mach III and fitted onto a catalog unit. In other cases, the length or diameter of the sheave may require modification of the unit to provide the proper support. Below are examples of each.C8D3K-STH--C8A2K-STH-P025-003_thumb2

 

The customer who purchased this C8D3K-STH heavy duty, end of shaft mounted friction clutch required a 15 Inch O.D. 3-5V groove sheave on the pilot. Mach III manufactured both the clutch and sheave and shipped the complete assembly within four weeks.

 

 

6085-007_thumb1

The customer who purchased this unit needed something similar to the catalog model C6D3K-STH, but with a 7.0 Inch diameter, 4-5V groove sheave which was too long and too small a diameter to fit on the pilot of the standard model. Mach III modified the catalog design by lengthening the unit and making the sheave an integral component mounted on bearings directly on the drive hub.

 

In addition to providing the required sheave, Mach III offers every catalog product with a range of bore and keyway sizes so customers are not required to modify their shaft or use bushings to obtain the correct fit. Also shipped with a rotary air fitting, these clutches are both out-of-the-box ready for quick installation.
