Abstract
A rotary actuator with optimized spur pinion and rack, pinion and rack of dissimilar materials and rack of weaker material, positively corrected pinion has twelve involute teeth and negatively equally corrected rack has a entire working composite involute profile and elliptical nonworking root profile, thereby improving performance without interference, with reduced vibration and noise.
Claims5
A rotary actuator with a spur pinion and rack arrangement comprising of:
- two pistons, each of the piston integrally connected to a rack, such that linear motion of each of said piston converts into a rotary motion in a pinion, the pinion and the racks being of dissimilar materials, said racks being of lighter and weaker material with respect to said pinion;
- wherein the improvement comprises said pinion consisting of twelve involute teeth and positively corrected, meshing on said racks of involute teeth and with a root strengthening and equally negatively corrected, and further the racks have a composite involute profile of teeth.
The rotary actuator with the spur pinion and rack arrangement substantially as hereinabove described in the specification with reference to the accompanying drawings.
