Synthetic gear grease ready for work in nacelles and elsewhere

A recently developed synthetic fluid gear grease is said to be ideal for manufacturers in industries that use centralized lubrication including wind, power transmission, and food. The synthetic fluid gear grease, NH1 94-6000, is based on highly refined synthetic hydrocarbon and a special calcium complex soap thickener. It is NSF H1 registered and therefore safe for incidental, technically unavoidable food contact.

The grease provides excellent wear protection even at a soft consistency of NLGI 000. At the same time, Klüberfood NH1 94-6000 is said to offer excellent corrosion protection along with good water resistance. This combination of special synthetic base materials also enables optimum lubricant supply in cold or refrigerated environments. Applied through the central lubrication systems, the lubricant can be used as gear grease for the immersion lubrication of toothed and worm gears or chains, as well as other friction points such as bearings and linear guides.

Mechanical grease can improve haptics for automotive interiors

A manufacturer of lubricants has developed a fully synthetic, high-viscosity grease for the lubrication of plastic parts inside cars. Klüber Lubrication says its Klübersynth RA 44-702 does not contain any silicone and mechanically dampens and reduces noise of slowly moving parts. The grease, which has no odor, can be used for both plastic/plastic and plastic/metal material pairings.

Oils or bonded coatings are applied to hundreds of points in every car, including brakes, steering assembly, engine components, gear shift, clutch and gears, or in seemingly minor components like door modules. Its manufacturer says Klübersynth RA 44-702 helps reduce oscillation, noise, and vibration and provides a pleasant high-quality feel when handling the car components, even at low temperatures. For example, the grease can greatly improve the feel of operating switches or adjusting armrests and seat rails. Other applications include mechanical switches and rotary controls, ventilation flaps, sun visors, ashtrays, cup holders, storage boxes and sunroofs.

Specialty lubricants for wind power jobs

A  manufacturer of lubricants has developed at least three gear oils for the wind-power industry. After extensive R&D and testing, Klüber Lubrication says its products meet the severe requirements of gear oil in wind-turbine drives:

Klübersynth GEM 4 N series (polyalphaolefin). These oils meet requirements of DIN 51 517–03, CLP. Corresponding gears can be switched to GEM 4 N oils without prior consultation with the gear manufacturer provided the crew follows general application notes. The oils offer a high scuffing load resistance. Gears are sufficiently protected against scuffing even at high peak loads. The oils’ high micropitting resistance offers sufficient protection to gears subject to high loads and would normally be susceptible to this type of damage.

Klübersynth GH 6 series (polyglycol)

Klübersynth GEM 2 series (rapidly biodegradable ester) achieves the scuffing load stage of API GL 5. Gears are sufficiently protected against scuffing even under high peak loads. GEM 2 provides much longer service life than mineral oils due to its excellent ageing and oxidation resistance of the base oil. Thus, maintenance intervals can be extended, and in certain cases, lifetime lubrication is possible. Owing to a wide service temperature range, a single viscosity grade can cover low and high temperatures in many applications.
The lubricants are said to provide excellent wear protection and resistance to micro-pitting, foaming, and residue formation. Compared with standard gear oil, these products show a high-load capacity, low-friction values, and good resistance to ageing. Consequently, oil change intervals may be increased while improving the efficiency and overall life of turbine components. In addition, the company’s ADDED value program makes it easy for manufacturers and operators to simplify their lubrication requirements.

Specialty lubricants for wind power jobs

Klϋber Lubrication, a worldwide manufacturer of specialty lubricants, will showcase three gear oil products for the wind power industry at Booth 9648. Following extensive R&D and testing, Klüber Lubrication has developed a line of products to meet the severe requirements of gear oil for wind turbine drives:

Klübersynth GEM 4 N series (polyalphaolefin)

Klübersynth GH 6 series (polyglycol)

Klübersynth GEM 2 series (rapidly biodegradable ester)

The lubricants are said to provide excellent wear protection and resistance to micro-pitting, foaming, and residue formation. Compared to standard gear oil, these products show a high-load capacity, low-friction values, and good resistance to ageing. Consequently, oil change intervals may be increased while improving the efficiency and overall life of turbine components.

Lubricant manufacturer at WINDPOWER 2010

Klüber Lubrication, a worldwide manufacturer of specialty lubricants, will showcase three significant gear-oil products for the wind power industry at the WINDPOWER 2010 trade show during May 23 through 26 in Dallas, Texas. Following extensive R&D and a comprehensive test program, the company has developed a line of products to meet the severe requirements of gear oil for wind turbine drives:

• Klübersynth GEM 4 N series (polyalphaolefin)
• Klübersynth GH 6 series (polyglycol)
• Klübersynth GEM 2 series (rapidly biodegradable ester)

Klübersynth lubricants provide excellent wear protection and resistance to micro-pitting, foaming and residue formation. Compared to standard gear oil, these products show good resistance to ageing, high load-carrying capacity, and low friction values. Consequently, oil change intervals may be increased while improving the efficiency and overall life of turbine components.

The company’s added-value program makes it easy for manufacturers and operators to simplify their lubrication requirements. For more information about Klüber’s lubricants solutions, please visit booth 9648 at WINDPOWER 2010 or the web site at www.klubersolutions.com/wind .

CanWEA attracts top OEMs

Officials for the Canadian Wind Energy Association (CanWEA) Annual Conference and Exhibition in Toronto say they sold out all 350-booth spaces to 235 exhibitors at the September event. The attendee count topped 2,000. What’s more, the conference drew ten utility and commercial wind turbine OEMs, a list that includes Acciona, Enercon, GE, Mitsubishi, Northern Power, and Siemens.

In conferences, several executives expressed a need for the loosening of credit to grow the market, which remains slower, they say, than most expected this late in the year. There was talk of supply-chain expansion as OEMs work to domesticate their version while other firms look to get started in North America.

There was good news for Ontario. The parliament for Canada’s largest province passed legislation for a Feed-in-Tariff ($0.19/kWh by one account) that will encourage new wind installations by providing fixed prices for onshore and offshore wind parks for the next 20 years. The law also calls for 25% domestic content for Ontario projects. That provision got high scores from local manufacturers.

In addition to OEMs, a range of support companies displayed equipment such as:

• NRG Systems (nrgsystems.com), a manufacturer of met masts and related equipment, showed devices such as 95-in. mounting booms for sensors, and sensors that assess wind shear and turbulence, and help calculate a total wind volume and density.
• Kluber Lubricants (kluber.com) had information on its oils and greases. Among its recent products were three synthetic lubricants for wind turbines.
• Thomas & Betts (meyersteelstructures.com) showed the Quickpin, one way to get away from slow-to-apply nuts and bolts that often attach line-support arms to power transmission towers. It is a long unthreaded pin placed in the same connection holes drilled for bolts, but secured without the precise torque required by conventional fasteners.
• Tyco Electronics (http://energy.tycoelectronics.com/elbow) introduced the 35 kV 600 Amp T-body elbow arrester. The device is intended to protect underground cables and high voltage apparatus from lightening and switching-transient surges.
• Carbone of America (carbonebrush.com) displayed several new slip-ring designs.
  

  Among the many new devices on display at CanWEA 2009 was the Tyco T-body elbow arrester. The devices are shielded and submersible, and meet performance requirements of IEEE C62.11.
