Holding Brake With Manual Override

clock June 17, 2016 11:17 by author Mach III Clutch

holding brake with manual overrideThis holding brake is used to secure a load on a hoist until it is required to be moved, at which point air pressure is applied to release the brake. However, if the power fails and compressed air is unavilable, the user needed the option to manually release the brake and move the load by hand.  Mach III engineers incorporated a lever that releases the brake manually when pushed in either direction.

  • D3C2R-005 Spring Engaged, Air Released Brake
  • Torque Rating = 461 pound inches
  • Brake remains engaged until air pressure is applied
  • Manual override lever can be used as an alternate method of brake release during power failure

Servo Motor Brake With Metric Input and Imperial Output

clock August 7, 2015 01:52 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.

Conveyor Clutches Last A Long Time When Properly Applied

MachIII_5004_1986Returned to Mach III for factory repair, the letters “JHG” were stamped in the housing of this multiple disc friction clutch which is used on an accumulating conveyor.  Under Mach III’s former date coding standard, this means the clutch was manufactured in October, 1987 – 28 years ago!

Designed for use at low air pressure to minimize wear, this clutch provides 2,300 pound inches of torque at just 30PSI and  includes integral 60A21 and 60B21 sprockets.  Mach III also produces combination clutch-brakes with integral double-single sprockets for chain driven live roller conveyor applications requiring a controlled stop to prevent drift of product, pallets or containers.



Holding Brake Connects Directly To Rotary Actuator

clock June 30, 2015 01:59 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 MACH024_CDS_iconcompletely custom brake solution was only 3 short weeks.

Torque Coupling with Morse Taper Input

clock March 25, 2015 09:10 by author Mach III Clutch

Used to open and close gate valves in water treatment and irrigation systems, this friction torque limiter coupling connects to a power drill with a #3 Morse taper socket. The coupling is pre-set at the factory to a torque value you specify and can be adjusted in the field if needed.  When the torque setting is exceeded, the coupling slips to prevent over tightening.

T4X2R-STH Torque Limiter + COUPL-032 Coupling

  • Male #3 Morse Taper Input
  • Torque Settings Between 10 and 233 Pound Feet
  • Coupling Shown Fits 2 Inch Square AWWA Operating Nut
  • Other Coupling Options Available

This design can be adapted for multiple uses, including mounted directly to a hand operated wheel (see our Taming the Gorilla article).

Clutch-Brake With Integral Pulley

W4K2H-002_Blog_266x266

This combination clutch-brake is similar to Mach III’s catalog model W4A2H-STH which has a ball bearing pilot on which a sprocket or pulley can be mounted. The pilot is driven when air is applied and held stationary when air is absent.  An application called for the unit to have a 36 degree, 3L groove pulley with a 3.96 Inch pitch diameter which is too small to fit on the pilot. Mach III modified the catalog model with a custom sleeve into which the pulley was machined, and a special drive hub which would accommodate the custom sleeve.  The modification added only one week to the lead time.

213TC to 182TC NEMA Frame Brake

clock July 25, 2014 11:24 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.
