Reinforced-tooth gear
Abstract
Abstract THE ROOTS OF THE TEETH OF A GEAR ARE INTERCONNECTED AT EITHER OR BOTH OF THEIR OPPOSITE ENDS BY REINFORCEMENT PORTIONS CONSISTING OF RIBS EXTENDING BETWEEN ADJACENT TEETH AND PROJECTING OUTWARD FROM THE BOTTOMS OF THE SPACES THEREBETWEEN. THE INTERMEDIATE PORTIONS OF THE TEETH OF THE GEAR HAVE RUNNING CONTACT AND ENGAGEMENT BETWEEN THE REINFORCEMENT RIBS AT EITHER OR BOTH ENDS OF A SIMILARLY-REINFORCED MESHING GEAR, SO THAT THE RIBS STRENGTHEN THE TEETH WITHOUT INTERFERING WITH THEIR ROLLING ENGAGEMENT OR "RUN-OFF". SUCH GEARS WITH RIB-CONNECTED TEETH ARE MADE BY SINTERED POWDER METALLURGY AS THE OUTWARD PROJECTION OF THE RIBS INTO THE SPACES BETWEEN THE TEETH FROM THE BOTTOMS OF SAID SPACES PREVENTS THEIR MANUFACTURE BY CONVENTIONAL GEAR-FORMING PROCESSES WHICH REQUIRE A RUN-THROUGH OF THE GEAR-FORMING TOOL BETWEEN ADJACENT TEETH.
