20 WIND POWER CARCOSEAL APPLICATIONS

21 WIND TURBINE COMPONENTS

22 CARCOSEAL APPLICATIONS Typical application : Main shaft bearing Rotor bearing Gearbox shaft Generator output shaft Blade pitch bearing Yaw bearing Typical Carco Products : Carcoseal/UN Carcoseal/UN/LA Carcoseal/SCA Customized rubber profiles

23 CARCOSEAL APPLICATIONS CARCOSEAL FITTED MAINLY ON MAIN SHAFT BEARING: -ENDLESS VERSION FOR NEW BUILD VIRTUALLY NO REPLACEMENT FOR THE ENTIRE WIND TURBINE LIFETIME (SPECIAL RUBBER COMPOUND RECOMMENDED FOR BEST FRICTION AND OZONE RESISTANCE) -SPLIT VERSION FOR RUNNING TURBINES REDUCING TO A MINIMUM MAINTENANCE TIME TO REPLACE OTHER OIL SEALS

24 We want the customer to save money CARCOSEAL rotary shaft seals NO LEAKAGE OF BEARING LUBRICANT NO CONTAMINATION OF BEARING LUBRICANT LONGER BEARING LIFETIME SPLIT VERSION AVAILABLE, SHAFT REMOVAL NOT NEEDED DOWNTIME REDUCTION MANPOWER COST REDUCTION LESS OIL SEALS PURCHASED BIG SAVINGS IN MAINTENANCE!

25 We want the customer to save money CARCOSEAL rotary shaft seals OTHER CLUES: - OUR OIL SEALS ARE EASY TO FIT - NO LEAKAGE THROUGH SEAL AND HOUSING - NO HOUSING DAMAGE DURING SEAL FITTING

Carcoflon PTFE surface treatment: No stick slip effect; Lip protection during dry running.

26 Retaining plate Carcoseal Benefits Rubber formulated with PTFE to reduce friction Stainless steel spring keeping lip homogeneously in contact with shaft. Carcoflon PTFE surface treatment: No stick slip effect; Lip protection during dry running. Friction reduction. Oil/Grease SEAL LIP SHAFT PTFE Large contact area: Guarantee against leakage; Less radial contact pressure; Less heat generation; Less shaft wear.

reducing friction and providing cooling.

27 MENISCUS EFFECT Lubricant is pumped into the contact zone by the shaft rotation and provides a separating oil film, reducing friction and providing cooling. The reverse pumping effect keeps the lubricant contained in the contact band.

leakage - quick screwing of the stainless steel garter spring - gluing on

28 Carcoseal Split version - straight cut into full rubber for better sealing - overlength on seal circumference to compress split area and prevent leakage - quick screwing of the stainless steel garter spring - gluing on site not needed for applications with no pressure - easy and quick seal replacement

29 Dedicated rubber compound for wind turbines: HT700 - Hydrogenated NBR with additives for longer working life. - Wide working temperature range: -45 / +150 C - Ozone resistant - Characteristics and compatibility with the most used greases have been verified by a third part laboratory. - Fully in accordance with FAG specifications: S HNBR75 for seals in wind power turbine

30 THE ORBITAL 2 PROJECT CARCO WAS RECENTLY INVOLVED BY AN ENGINEERING COMPANY INTO THE SEAL DESIGN OF A NEW GEARBOX FOR A 3 MW WIND TURBINE. THE BIG GEARBOX IS CONNECTED DIRECTLY TO THE ROTOR. THE SHAFT DIAMETER IS mm 1750 AND 2 SEALS ARE DESIGNED TO KEEP LUBRICANT INSIDE THE BIG BEARING AND TO PREVENT LUBRICANT TO BE CONTAMINATED BY DUST AND OTHER POSSIBLE AGENTS. CARCOSEAL/SCA/SPLIT FITTED BACK TO BACK WAS RECOMMENDED. SPLIT VERSION TO EASE SEAL FITTING. H-NBR COMPOUND TO GUARANTEE THE LONGEST SEAL SERVICE LIFE.

ORIGINAL OIL SEALS: TOO SOFT STEEL UNDER CHROMIUM COATING.

31 PROBLEM SOLVING FROM CARCO CARCO SPECIALISTS INSPECTED A 1,5 MW WIND TURBINE IN SPAIN. WE DETECTED BIG GREASE LEAKAGE FROM MAIN SHAFT BEARINGS DUE TO DEEP GROOVES ON THE SHAFT SLEEVE FROM ORIGINAL OIL SEALS: TOO SOFT STEEL UNDER CHROMIUM COATING. WE SUGGESTED TO MOVE THE SEAL INSIDE THE HOUSING WITH A SPACER IN ORDER TO CHANGE THE CONTACT AREA ON THE SHAFT. WE DELIVERED CARCOSEAL/UN/SPLIT WITH FULL SATISFACTION OF THE CUSTOMER.

General information on radial seals

170 General information on radial seals Radial seals is the common name for shaft seals, which seal against a rotating shaft using an elastic and resilient lip of rubber or PTFE. The lip in turn is either
