Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
162 words
THE METHOD OF MANUFACTURING A GEAR MOTOR COMPRISING, ATTACHING AN OPEN ENDED GEAR CASING TO ONE END SHIELD OF AN ELECTRIC MOTOR, WITH THE MOTOR SHAFT EXTENDING THROUGH A SIDE WALL OF SAID CASING INTO THE INTERIOR THEREOF AND CARRYING A PINION WITHIN SAID CASING, PLACING AN OUTPUT GEAR AND SHAFT IN SAID CASING WITH SAID OUTPUT SHAFT EXTENDING OUT OF SAID CASING, PLACING END COVERS OVER THE OPEN ENDS OF SAID CASING WITH AN UNHARDENED ADHESIVE BEING APPLIED BETWEEN SAID END COVERS AND SAID CASING, AND ASSEMBLING BEARINGS CARRIED BY SAID END COVERS ONTO SAID OUTPUT SHAFT, ADJUSTING SAID END COVERS AND SAID OUTPUT GEAR TO PLACE SAID OUTPUT GEAR INTO PROPER MESHING RELATION WITH SAID PINION AND WITH SAID BEARINGS ALIGNED BY SAID OUTPUT SHAFT, AND HARDENING SAID ADHESIVE WHILE SAID END COVERS ARE HELD IN THE ADJUSTED POSITION, THEREBY TO FIX SAID END COVERS TO SAID CASING IN THE ADJUSTED POSITION AND COMPLETE THE ASSEMBLY OF SAID GEAR MOTOR.
