Servo Motor Brake With Metric Input and Imperial Output

clock August 6, 2016 17:52 by author Mach III Clutch

D8C2K-001_A_PA manufacturer of thermoforming machines needed a holding brake. They wanted to continue to use a servo motor made in Japan and a gear reducer made in the USA but no one offered a brake that could go between  the different faces of the two components. Faced with either costly design changes or abandoning one of these trusted components, the OEM approached Mach III for a solution.

Mach III solved the dilemma with this spring applied, air released friction brake.  The output side of the brake (top photo) has a 1.625 Inch Shaft with standard keyseat to connect to the USA-made imperial gear box. The input side (bottom photo) has a 55mm bore and  features a locking collar which connects the brake to the Japanese metric motor. 



Servo Motor Brake Holds When Power Is Off

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

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.

X5C2R-004_highres_outlinedIn addition NEMA Frame mounted models, Mach III also produces clutches, brakes, clutch-brake combinations and torque limiters to IEC Flange standards.  The model pictured is a combination air applied clutch – spring applied brake.

  • Part Number:  X5C2R-004
  • IEC 100 Frame, B5 Flange
  • 28mm Input Bore and Output Shaft
  • Clutch Torque:  495 lb-in @ 80 PSI
  • Brake Torque:  197 lb-in, 20-30 PSI Release

NEMA and IEC models are available also a variety of finishes:  aluminum, anodized aluminum and stainless steel, making them suitable for food processing and packaging applications.

213TC to 182TC NEMA Frame Brake

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.

Custom Design Solutions: Metric To Imperial Servo Motor Brake

clock June 8, 2010 15:38 by author Mach III Clutch

A manufacturer of plastic thermoforming machinery needed a replacement for a troublesome caliper brake but no manufacturer offered a servo brake that would match D8C2K-001 004the Japanese built servo drive (metric) and a U.S. made gear reducer (imperial).  Mach III saved the OEM the expense of modifying the machine design by creating a c-face, spring applied brake to fit between the two components.  This example has a 55 mm input bore and a 1.625 Inch output shaft.  Torque rating:  6400 pound inches, 58 PSI release.
