Open gear drives have been offering proven service for decades, often under tough conditions in ore and cement processing, coal production, in fertiliser and chemical plants, in sugar refineries, and in waste and composting plants. In addition, open gears are also used in the marine and wind power industries. What all applications have in common is the high level of reliability, longevity and operational safety required of the systems. High forces, shock loads and relatively low circumferential speeds lead to predominantly mixed friction conditions in the tooth contact of open gears. Optimum lubrication of the gear wheels helps to reduce the friction and hence wear and damage to the tooth flanks. In this way, the efficiency of the systems and their service life can be extended. This increases productivity – and profitability with it.
Klüber Lubrication develops and produces specialty lubricants for large girth gear drives. The product range includes gear greases with solid lubricants as well as high-viscosity fluids. For both technologies, specialty lubricants for the priming, running-in, operation, repair and cleaning of girth gear drives and open gears are available. This A-B-C-D-E system lubrication developed by Klüber Lubrication covers the entire service life of the open gear drives and has offered proven service in industrial applications for many years. A multitude of OEMs have certified lubricants from Klüber Lubrication for their open gears.
High-viscosity fluids used as a service lubricant – Type C
Service lubricants for open gears reduce wear and contribute to long gear service lives thanks to excellent gear protection. The specialty lubricants from Klüber Lubrication deliver low consumption and optimum friction values, good adhesion and optimum load-carrying capacity. Lubricant detection is made easy with UV indicators.
Gear grease with solid lubricant content used as a service lubricant – Type C
These types of grease containing solid lubricants for open gears also fall under the type C service lubricants. They offer operational reliability confirmed by decades of experience. The contrast with the gear material makes it easy to visualise the contact pattern.
Repair lubricants – Type D
These repair lubricants are used for reconditioning the tooth flanks of open gears. They can be used to compensate for surface irregularities, scratches and scuffing and thereby improve the contact pattern. At the same time, they also help to reduce the roughness of the tooth flanks, bring vibrations down and achieve a more uniform, lower gear temperature. This extends the service life of the gears.
Cleaning lubricants – Type E
Specially for the cleaning of open gears, Klüber Lubrication has developed an environmentally friendly specialty lubricant that can be used while large gear drives are in operation. This means that there is no need for dangerous manual cleaning, thus eliminating downtime and increasing productivity.
When it comes to the use of Klüber Lubrication specialty lubricants for open gears, the company provides its customers with support in the form of comprehensive services – from the inspection of existing applications involving comprehensive measurements and lubricant analyses to the technical documentation and the repair and tooth flank treatment with unique products. In addition, the company’s lubricant experts provide its customers with assistance on the optimisation of centralised lubricating systems and application processes.
