1 MOTION TECHNOLOGY ROTARY UNION DESIGN GUIDE

2 TABLE OF CONTENTS PRODUCT DISCLAIMER The function of a rotating union is to separate the working media from the environment. Duff-Norton rotating unions are contacting seal type rotating unions and will allow leakage to some degree, as will all similarly designed and manufactured products. It is important to note the leakage of rotating unions will increase over time as the contacting seals wear. All persons specifying, installing and operating the rotating union must take note of this potential risk. The information in this catalog is supplied upon the condition the persons using Duff-Norton products will make their own determination whether this leakage may be dangerous, unsafe or cause damage of any nature whatsoever.

7 APPLICATIONS Kaolin Processing The calciner removes the kaolin from the kiln at around 11 F and cools it down to 14 F in preparation for packaging. The kaolin comes from the kiln in a powder form, while cooling water runs through screw conveyors which are hollow on the inside. Cheese Production An ammonia cooling wheel is used in a cheese manufacturing clean room. The cooling wheel extracts the cheese curd and chills it into a solid form, which is then sliced and individually wrapped with plastic. This application uses a sophisticated leak detection system that automatically shuts the machine off if a leak is detected.

34 2 SERIES SHOCK & VIBRATION RESISTANT The unique design of this 2 series flanged type joint permits them to be used to introduce heating and cooling agents into rolls or cylinders in various types of machinery. Models are available to handle water, oil and other fluids in applications requiring sealing pressure to 15 psi, speeds to 5 rpm, and temperature to 55ºF when specified Flexible Hose Eliminates complex piping, allows adjustment of rolls without repiping. Allows rotary joint to float so as to avoid unnecessary strain on sealing surfaces. A flexible hose either rubber or metal - must always be used with rotary joints. 2 Flanged Inlet Elbow of steel is a 15 lb. ASA flange type. 3 Flanged Rotating Housing Prevents leakage under pressure and protects the internal parts for a long service life. The flanged housing attaches directly to the machine journal, providing inherently concentric mounting, minimizes overhang. The housing may rotate in either direction without causing back out problems. 4 Stationary shaft Is constructed of steel. It serves as a conduit for the fluid transfer from the flanged inlet into the revolving flanged housing. 5 Lubrication Fitting Located on the stationary shaft allows lubrication of the ball bearings while the rotary joint is in operation. 6 Two Single Row, Widely Spaced Ball Bearings For radial and thrust loads. 7 Grease Ring Assembly Made of steel, ground and spaced for ball bearing load sharing for increased life. 8 Drain Ring Made of steel. It allows minute start-up leakage from entering the ball bearings. 9 Seal Ring Forms the primary rotating seal with the face ring. Order Checklist Supply the following information when ordering 1. Desired bolt circle 2. Bolt hole size 3. Number of bolt holes and spacing 4. Desired flange thickness 5. Flange O.D. 6. Pilot diameter and type 7. Pilot (length or depth) Ph: (8) Fax: (74) The seal ring is constructed of carbon graphite to provide a low friction, wear resistant surface. 1 Gasket Provides an effective seal between the housing and the fluid chamber. 11 The Face Ring Constructed of hardened and tempered stainless steel mates with the seal ring to form the primary seal. 12 O-Ring Elastomer (not shown) Made of ethylene propylene for hot water applications. For higher temperature applications, a perfluoroelastomer is used. 13 Compression Springs Apply an initial pressure between the face ring and seal ring to provide sealing for low pressure applications. 14 Drive Collar Keys the face ring and the shaft together to prevent rotation. 15 Retainer Rings Secure the internal components to the shaft. 16 Flange Secures Secures the internal components within the flanged housing. This allows quick rotary joint repair and less machine downtime. Dimensions - 2 & 9 Bolt & Flange Shaft I.D. Minimum Bolt Circle Bolt Circle (B) Cap Screw Diameter 7 1 Max. Flange Diameter (A) Max.

76 ENGINEERING GUIDE DESIGN While rotating joints come in many shapes, sizes, and configurations, they always have the same four basic components: housing, a shaft, a bearing (or bearings) and a seal. Housing Mechanical Seal Bearing Shaft Mechanical Seal 76 The heart of the rotary union or rotary joint is the seal. The seal prevents the medium (water, oil, air, etc) from leaking outside the rotary union while the rotary union is in operation. Duff-Norton uses four basic types of mechanical seals in its rotary unions: 1) pusher-type end face mechanical seal, 2) non-pusher type end face mechanical seal, 3) lip seals and 4) o-ring seal. Rotary unions may have more than one seal. Bearing The second most important part of the rotary union is the bearing. A rotary union may have only one bearing or multiple bearings. Roller bearings, such as ball bearings and tapered roller bearings, or non-roller bearings, like graphite bearings and bronze bushings, may be used in the rotary union. The bearings are always used to allow a part of the joint, either the shaft or the housing, to rotate. Shaft The shaft is the component that carries the medium through the rotary union into the drum or roll. In many cases, the shaft will turn with the drum or roll. In some cases, like in larger flanged rotary unions, the shaft may be stationary while the housing rotates. The bearings and seal are typically assembled around the shaft. Housing The housing is the component that holds all of the other elements of the rotary union together. The housing has an inlet port, which is a threaded port to which the hose supplying the medium will be attached (See the next page for recommended hose installation). The rotary union may also have an outlet port, if the same joint is being used both to supply fluid to a roll and to remove fluid from the roll. In smaller rotary unions, the housing is stationary. In larger rotary unions, the housing maybe bolted to the drum or roll using a flange. In these cases, the housing rotates at the same speed as the drum. Ph: (8) Fax: (74)

78 ENGINEERING GUIDE RECOMMENDED HOSE INSTALLATION Flexible hose must be used to connect each rotary union to its supply or drain piping. Use braided metal hose for all applications involving hot fluids, such as hot water, hot oil or steam. Use two-ply rubber hose for cooling water, refrigerants, air and vacuum service. Allow for an offset between the rotary union joint and the rigid pipe as shown in Exhibit C. It is important to allow a slight curve in the hose to allow the hose to float. This will prevent a side load from being placed on the rotary union. A side load will greatly reduce the life of the rotary union.
