The Design of the Rotary Drive Mechanism of the front Frame Positioner in a 5 Tons Loader
Abstract: Welding positioner has becoming indispensable manufacturing equipment，in the welding area it designated as welding auxiliary machines. The form of series and varieties specifications about more than ten series and hundreds varieties, it is becoming an emerging industry. This topic is to design about 1 ton of reproduced machine frame welding displacement machine rotary actuator . Main content is: the welding in Y and Z displacement machine two rotation degrees of freedom transmission design, supporting structure design, the choice of motor, speed reducer, the determination of the shaft and bearing as well as check and so on. Specific process of the design is determined according to the requirement of the specification required for motor types, including speed, rated power, etc., on the basis of cycloidal pinwheel reducer, coupling, worm gear and worm reducer, gear and slewing bearing parts, and to check related data. Finally, using the CAD software to draw the related detail pictures, assembly pictures etc.
Key words: Welding positioner；Rotary actuator design；Reducer; Slewing bearing
