1、McKissick Sheaves Copyright 2002 The Crosby Group, Inc.211 All Rights Reserved McKissick Sheaves McKissickSheaves McKissick Roll Forged TM Sheaves Stepped hub design proves better. The McKissick hub is stepped to eliminate stress failure in the weld, common in traditional hub designs. The hub is pre

2、ssed into place with complete metal-to- metal contact. This helps ensure an accurate alignment to the hubs axis so theres no wobble or lopping of the rotating sheave. The precision aligned hub/sheave wheel combination adds to the bearing life and keeps the sheave on the job longer. Closed die upset

3、and roll forged not split. Upsetting and roll forging forms the groove and flange walls in multiple steps, eliminating the need to split and weaken the groove. This exclusive forging process adds extra strength to the critical groove section. You can count on a McKissick sheave to give maximum life

4、performance, because its forged to distribute the wire rope forces evenly over an accurately formed load sur- face. Plus, uniformity of the roll forged groove adds longer wire rope life. Full range of standard sheave sizes. McKissick roll forged sheaves are available in a full range of sizes from 12

5、 inches to 72 inches, and bearing styles and prices that best fit your application. Crosby also manufactures custom McKissick sheaves and can make minor modifications to standard sheaves as needed for special applications. Solid steel no castings. Every McKissick sheave starts as a single piece of s

6、olid carbon steel plate. Its flame - cut from closely checked stock, so theres no inher- ent web/rim flaw as you find in cast sheaves. Theres better balance and better distribution of forces with a McKissick roll forged sheave too. Casting can result in groove wall variations - either too thick or t

7、oo thin - causing uneven stresses and early failure. Flame hardened groove. Crosbys hardening technique is a science. It provides a precise maximum hardness for wear- resistance across the wire rope contact area. The McKissick sheave groove is flame hardened to a minimum 35 Rockwell C for a 140, con

8、tact area with the wire rope. The solid steel plate pro- vides the ideal surface for flame hardening and a closer tolerance fit to the wire rope to reduce fatigue and wear.

14、ckRoll Forged Sheave CONFIGURATOR The McKissickRoll Forged Sheave CONFIGURATOR system has been developed to simplify the selection and ordering of McKissickRoll Forged sheaves. Although McKissickcan custom manufacture any Roll-Forgedsheave to your exact re- quirements, we have developed a system to

15、allow quick and easy selection of the proper standard McKissickRoll Forged sheave required to meet your applications. Using standard sheaves will reduce the lead time in getting the sheave to you, thus saving time and money. For more information, see page 337, or contact your local authorized Crosby
