<p>#CMT# #/CMT# The device e.g. delta robot (10), has three actuating arms (18) pivotable about a transmission axis (s), where each arm is connected to a motor/transmission unit (16). A carrier element is provided for arranging a gripping unit to grip an object, and an articulation axis (m) is connected with another articulation axis (n) of the carrier element over a pair of connecting bars. The connecting bars stabilize ball joints (24, 34) connected together, and are made of an elastic material and connected together by a pre-tensioning element (48) made of a rigid material. #CMT#USE : #/CMT# Device for displacing and positioning an object in space. #CMT#ADVANTAGE : #/CMT# The connecting bars stabilize the ball joints connected together, and are made of the elastic material and connected together by the pre-tensioning element made of the rigid material, thus reducing pretension force based on higher spring stiffness to reduce abrasion wear, accurately defining a defined undersize of distance of the connecting bars, increasing overall rigidity, and providing improved oscillating and damping characteristics. The device blocks axial rotation of the connecting bars in mounted position, enables cost-effective production, installation and maintenance of the device, enables mass production, and ensures material stability in diverse working environment. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of a delta robot. m, n : Articulation axis s : Transmission axis 10 : Delta robot 16 : Motor/transmission unit 18 : Actuating arms 24, 34 : Ball joints 48 : Pre-tensioning element #CMT#POLYMERS : #/CMT# The pre-tensioning element has retaining parts made of rigid material such as rigid plastic material.</p> |
