Abstract
The method includes providing a motor having a drive shaft mounting a pinion profile having an outside diameter and a mounting collar surrounding the shaft, the collar having an outside diameter less than the outside diameter of the gear. A gearbox wall formed with an opening having a generally ring-gear shape larger than the pinion and an inside diameter substantially the same as the outside diameter of the collar. The pinion is maneuvered through the opening and the collar is pressed into the motor-mounting opening. The invention is also the structure of the finished assembly including the opening.
Claims3
A method of assembling a motor to a gearbox wall comprising the steps of:
- a. providing a motor having a drive shaft mounting a gear formed with a toothed profile having an outside diameter, and a mounting collar surrounding the shaft, the collar having an outside diameter less than the outside diameter of the gear,
- b. providing a gearbox wall formed with a motor-mounting opening having an inside diameter formed with a toothed profile similar to but larger than the toothed profile of said gear and inside diameter substantially the same as the outside diameter of the collar,
- c. maneuvering the spur gear through the motor-mounting opening and pressing the collar into the inside diameter of the motor-mounting opening.
A drive assembly comprising a motor including a shaft mounting a spur gear having teeth and an outside diameter, the shaft having a mounting collar with an outside diameter of lesser diameter than the outside diameter of the spur gear, and a gearbox wall formed with a motor-mounting opening of generally circular shape having an inside diameter and formed with outward notches formed uniformly about its periphery, the notches being larger than the teeth in the spur gear, the shaft and spur gear extending through the opening and the collar snugly fitting into the inside diameter of the opening.
