HYDRAULIK PNEUMATIK

extremely lightweight construction, compact form - material combination of aluminium alloys and modified plastics produces extremely low weight rotary actuator the torque is equal in both directions of rotation and across the entire angle of rotation outstanding sets of slide combinations, low-friction seals and rolling friction in the reversing grooves produce optimum efficiency adjustable drive shaft datum (standard) allowing exact positioning of the drive shaft keys, therefore - '‘"facilitating the machining of the coupling - permitting re-adjustments whenever required the design of the...

large-area press-fit joint HYDRAULIK PNEUMATiK ECKART externally adjustable end stop (standard) _ - the angle of rotation as supplied can be re-adjusted at any time to within ± 5° while the shaft adjust facility will provide the required position of the keys Dimensions and technical data 8 - standard rotations are 90°, 1 80° and 360° - any intermediate angle of rotation, including over 360°, can be supplied -

suggested circuit diagram PSM without end cushioning Operation - Around the circumference of the piston K (figure 2) are curved grooves K1 into which the guide rollers R1 engage. - On applying pressure via the ports PI and/or P2, the piston K is moved. - When the guide rollers R1 engages into the curved grooves K1 the piston K is forced into a rotary movement. - This rotary movement is transferred via the guide rollers R2 to the shaft W. - The rotary movement is transferred via the curved grooves keys K2 in the shaft W which rotate in the opposite direction to the curved grooves K1. - The...

Initial drive shaft position The initial drive shaft position can be set in the angular minute area. All models dre supplied 90° offset to the position shown in figure 2 with piston K resing against stop X. , After loosening the screws Z []/i turn), any drive shaft or key position can be adjusted. Once the required adjustment has been made, tighten the screws Z again. Torque output The stated torque figures are effective torques, with the pressure versus the torque curve being virtually linear. Heavy duty, multi-shift or high frequency applications require a safety factor between 1.2 and...

Technical data: proximity switch: nominal switching distance: operating voltage: load current: connection type: protection class: Dtions SZ - Locating pin The pin (figure 3) allows fitting of cams (option Z5) or other control equipment and screws into the tapping provided at the back end of the shaft where it can be secured with a metal adhesive, if.required. It should not be used for torque transmission or limiting the angle of rotation. ZS - Cam The cam Z5 (figure 3) is clamped onto the locating pin SZ and serves to operate the proximity switches. If two proximity switches are required,...
