Deublin SpindleShield? Unions for CNC Machining CentersWHAT IS AN ELECTRICAL SLIP RING?

A slip ring is an electrical device that allows the transmission of power and electrical signals from a stationary to a rotating structure. Also called a rotary electrical joint, collector or electlic swivel, a slip ling can be used in any electro-mechanical system that requires unrestrained, intermittent or continuous rotation while transmitting power and/or data. Slip rings are similar in concept to a rotating union, but for transmitting electric current rather than media.

Deublin is the proven leadeing manufacture of rotary unions for hydraulic pitch control in wind turbine applications. Now Deublin provides Slip Rings to serve the demanding requirements of electric or hydraulic wind turbine pitch control applications.

HOW DOES ASLIP RING WORK?

Typically, it is comprised of a graphite or metal contact brush which rubs on the outside diameter of a rotating metal ring. As the slip ring turns, the electrical current or signal is conducted through the stationary brush to the metal ring making the connection. Additional ring/brush assemblies are stacked along the rotating axis if more than one electrical circuit is needed.

HOW IS THE SLIP RING MOUNTED?

Slip rings are designed for rigid mounting through an adaptor plate or bracket to the end of the hydraulic union. They can be mounted on either the rotor end or opposite end cap depending on the application. Typical mounting configuration is in a horizontal axis.

Deublin Slip Rings were developed in response to wind turbine manufacturers' demand for longer lifetimes. This integrated system has been optimized with special material configurations that are rated for millions of cycles, which translates into many years of trouble-free operation for unsurpassed performance. This progression of Deublin technology has generated unparalleled lifecycle reliability, which in turn, significantly reduces maintenance costs.

As with all Deublin products, our slip ring system is 100% tested prior to installation in the field, and manufactured using high performance production methods. The long-life slip ring technology will provide consistent, reliable service and maintenance-free performance for both on- and off-shore operations. Wind Energy plays an important role in the world's energy requirements, and Deublin is proud to serve the industry.
