Power Off Brake For Short Axial Shaft

clock June 19, 2017 14:45 by author Mach III Clutch

The Need:D5F2R-001gif

  • Minimum 600 pound inches to hold a shaft stationary when air pressure (power) is absent.
  • Brake must fully release when 60 PSI is applied.
  • Ample radial space available to connect the brake housing to the machine frame, but . . .
  • Only 2.125 Inches of an un-keyed,  1.687 Inch round shafting extends from the  machine frame.

The Solution:

  • Custom brake design uses a shrink disc to lock the brake hub onto the shaft.
  • Brake housing connects to the machine frame on a 6.563 Inch Bolt Circle.
  • Brake provides 1,200 pound inches of brake torque, fully releases at 59 PSI.

Slip Clutch Adapted For Diameter Restriction

clock September 16, 2015 06:14 by author Mach III Clutch

T4A4H-001_highres_outlinedThis mechanical friction torque limiter was created in response to a customer’s request for a slip clutch with a 3180 pound inch setting and a 44L100 pilot mounted pulley. The first challenge of this application was that the outside diameter of the torque limiter could not exceed the diameter of the pulley. Mach III designed this unit with eight friction surfaces to deliver the required torque within the diameter restriction. 

The second challenge was that the unit had to fit on a 1.25 Inch shaft.  The design could accommodate a 1.25 inch bore, but there was no room for a keyway.  Mach III extended the drive hub and fitted it with a locking collar to connect the torque limiter to the shaft.

Thinking OUTSIDE The Box Kept This Solution INSIDE the Box

clock October 31, 2012 12:49 by author Mach III Clutch

An arm used to position components during the assembly of an aircraft had problems with overload when it went into use. The arm was articulated by a timing belt pulley located at the pivot point that was driven by a belt connected to the motor. Extra load put on the wing assembly transferred backward through the arm to the motor. A torque limiter would resolve the issue, but there was only one inch of axial space available between the pulley and frame in which it could be placed.

Nothing existed that was that thin and would deliver the needed 530 pound inches of torque required. It appeared redesign and rebuilding of the arm might be the only option, one which would be both time consuming and costly. 

Luckily, Mach III’s engineering team figured out how to combine the timing belt pulley and torque limiter into one component. Nothing had to be moved; even the belt position was maintained. Just as remarkable, Mach III expedited production to keep the maker of the assembly arm out of hot water with their client. Only 12 days after the application was presented to Mach III, 5 complete torque limiter/pulley assemblies arrived onsite.

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: Foot Bracket Mounted Clutch-Brake

clock June 8, 2012 10:43 by author Mach III Clutch

Mach III commonly modifies catalog products and designs entirely unique assemblies to match customer’sBinder Clutch mounting requirements.  In this example, Mach III’s customer sought an alternative for the electric combination clutch-brake shown on the right.  The original unit was manufactured outside the US, was costly and had a unacceptably long lead time.  After obtaining the application specs to determine the required clutch and brake torque, Mach III designed a drop-in replacement.  Time to complete the application review, design process and production of the unit was just 5 weeks.

Custom Model:  X5M1H-001X5M1H-001 013

  • Combination Air Engaged Clutch and Spring Engaged Brake
  • Clutch Torque Capacity:  741 pound inches @ 80 PSI
  • Brake Torque Rating:  163 pound inches (spring set) with 20-25 PSI release
  • 20mm Diameter Output Shafts with Standard Keyseat

Conway 858-14 Stationaire Clutch Mechanism Replacement

P1010002

Motion Industries contacted Mach III Clutch searching for a replacement for a Conway 858-14 Stationaire Clutch Mechanism sought by a paper mill.  The original clutch and adapter are underneath the guard in the picture on the right.  After reviewing the application along with photographs and drawings provided by the customer, Mach III designed the MBR3K-001.  An eleven inch friction diameter clutch with a 2.9375 Inch bore, the MBR3K-001 assembly (pictured below) includes both the clutch mechanism and a custom adapter flange.   The design is a variation of Mach III’s catalog model Heavy Duty Clutch Mechanism.  Mach III frequently adapts catalog models to match the specifications and mounting requirements of the application.  Lead times for such customization are typically only a week longer than for catalog products.

Mach III has assisted a number of customers seeking items no longer available from Conway Clutch.  While it is helpful to know the model number of the current Conway unit, it is more important to understand how the clutch is mounted and the function it is required to perform.  Digital photos or a sketch of the clutch and how it relates to the existing drive train are particularly useful.  For assistance replacing a Conway clutch or with any retrofit application, contact Mach III’s engineering department.



Custom Design Solutions: Metric To Imperial Servo Motor Brake

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.

Conway 858 Series Clutch/Brake Combination Replacement

clock October 30, 2009 13:28 by author Mach III Clutch

The photograph below shows a pair of Conway 858 series clutch mechanisms used on a Norton Hyprolap lapping machine.  Both units are mounted on a common shaft with one acting as a brake and the other as a clutch.  Due to the design of the machine, diameter and length were very limited.  To provide a drop-in replacement, Mach III created the M5R2K-001 clutch mechanism (link to drawing below) by combining the catalog-standard M5R2K-STH clutch mechanism with a custom designed adapter.  The pair cost the owner of this machine less than $2,000.00 USD and saved the additional expense of machine modification.

Mach III has assisted a number of customers seeking items no longer available from Conway Clutch.  While it is helpful to know the model number of the current Conway unit, it is more important to understand how the clutch is mounted and the function it is required to perform.  Digital photos like those on the right or a sketch of the clutch and how it relates to the existing drive train are extremely useful.  Contact Mach III for assistance replacing a Conway clutch or with any retrofit application.
