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.

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 made modifications to reduce the size of the internal components so that the pulley could be incorporated directly into the sleeve.

Conveyor Clutches Last A Long Time When Properly Applied

clock July 29, 2013 15:33 by author Mach III Clutch

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.

Custom Combination Air Set Clutch & Air Set Brake

Z3A1H-158

Mach III’s catalog model clutch-brakes require only one air signal to engage the clutch.  Clutch torque is linear in relationship to air pressure applied.  The brake engages automatically with spring pressure as soon as air is exhausted from the clutch at a fixed value. 

Sometimes, however, a client requires more torque than can be provided with the catalog design.  This custom model incorporates both an air set clutch and air set brake.  The clutch and brake are controlled with  separate air signals (see air inlets marked “B” for brake and “C” for clutch) and torque can be varied in both the clutch and brake portions of the assembly.

Ultra Compact Friction Clutch With Double-Single Sprockets

clock January 21, 2013 18:00 by author Mach III Clutch

C3D1Q-001Developed as a retrofit replacement for a tooth clutch, this compact air actuated friction clutch provides . . .

  • 208 pound inches torque @ 80 PSI
  • 4.49 inches overall length
  • 1.0 inch bore
  • Double-single 60A19 sprockets
  • Enclosed construction 

. . . and unlike a tooth clutch, it provides a soft start and can be engaged dynamically at higher speeds.

This clutch is designed for use in a chain driven live roller conveyor.



Clutch with Elongated Pilot Provides Proper Pulley Support

clock December 5, 2012 13:01 by author Mach III Clutch

For this low speed application, a Mach III end of shaft mounted clutch with a bronze bushing pilot was required.  The pulley the customer intended to use, however, was too wide for the pilot of the catalog model clutch and would have resulted in an overhung load.  Operating a clutch with an overhung load will cause uneven and premature wear and may result in the clutch “walking” off the shaft. 

Overhung Load

To accommodate the pulley, Mach III produced the pictured clutch which is similar to the catalog model only with an elongated pilot.  The elongated pilot provides proper support for the pulley by centering it over the bronze bushing.  For guidance on proper attachment of sprockets and pulleys, download our eBook:  Mounting Sprockets and Pulleys on Pilot Style Clutches



High Torque Clutches for Low Pressure Operation

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: 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: 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.
