Design and Performance Upgrades for Pick & Place Universal Joints
July 1, 2018
Belden Universal, a global manufacturer of custom universal joints and specialized mechanical power transmission products, has recently implemented critical design upgrades to its universal joints for pick & place (Delta) robots. "The redesign project was necessitated by industry demand, from both OEMs and end users, for space-saving components supporting heavier payloads," said a company spokesperson.
The stainless steel component is based on Belden's unique hybrid design, combining the higher torque capacity of a pin + block joint with the needle bearing's ability to continuously operate at high speeds with low friction. It mitigates corrosion issues, contamination, burnout and joint seizure.
The redesign project concentrated on the joint's center section. It utilizes stronger, precision needle-roller bearings with larger outside diameters, making it capable of supporting applications with larger payloads and higher torque requirements. Torsional backlash was minimized according to stringent specifications. Modifications to the yoke's ear profile resulted in a higher, 55° angle, further supporting precise positioning and orientation of the robotic arms. "With an overall length of 48 mm, the universal joint delivers a compact, space-saving design offering high strength, speed and flexibility," said the spokesperson.
