Sectional Rail Coupling (PKV) by JAKOB Antriebstechnik GmbH

JAKOB Antriebstechnik offers sectional rail couplings, that can be used with all current sectional rails. They are attached to existing sectional rails of various brands either directly or via adapter plates, which makes them an excellent choice for retrofitting. They can be disconnected either vertically or horizontally. The patented force amplification via wedge clamping mechanic is able to compensate a gap of up to 5mm between active and passive part. This clamping kinematic ensures high stiffness and precision of the connection. The generation of the clamping force can be achieved either manually by the operating hex head or pneumatically (PN=6 bar). High operational safety is ensured by electrical indication of clamping status and maintaining of minimal clamping force even in case of pressure loss.

PKV - Design Characteristics
The coupling is comprised of an active and a passive part made from tempered steel. In the active part, the clamping force is generated by a combination of an axially sliding locking bolt and a mechanical clamping gearbox. This design allows for high clamping forces and dynamic stiffness while keeping weight at a minimum. For tool changing, a vertical stroke „K“ (see data sheet) is required. Type PKV is available in two different versions - the fully automated pneumatically driven PKV-P and the manually operated PKV-M.

About JAKOB Antriebstechnik GmbH

JAKOB Antriebstechnik GmbH is an internationally leading manufacturer of servo couplings, safety couplings, and mechanical clamping elements. For more than 40 years JAKOB has been developing and producing various types of torsionally stiff metal bellows couplings and safety couplings for the servo drive industry. Throughout our history we have earned ourselves a reputation of being a reliable and competent partner in the motion and drive industry.

JAKOB is the market leader in the area of mechanical tool and component clamping with its innovative and unique clamping technology.

The JAKOB wedge clamping technology provides the highest clamping forces with low actuation torques and, at the same time, maximum operational safety. The goal of our servo and safety coupling catalog is to provide a general overview over our standard product range. Highly trained engineers and technicians at our facility in Kleinwallstadt are always ready with a solution to best meet your requirements.
