Befestigungs-System für Motor eines Fadenschneider

摘要

A motor mounting plate system enables a motor to be mounted within a string trimmer without the need for a plurality of precisely formed ribs to support the motor within the housing. The motor mounting plate apparatus (38) includes a planar mounting plate member (40) and a U-shaped bracket member (52) which are secured together to form a rigid motor mounting assembly. The U-shaped bracket member is connected to the stator of the motor (36) of the string trimmer. A lower portion of the housing includes two housing halves, each including a groove (26b) formed therein. The outer perimeter of the motor mounting plate is positioned in the groove of one of the housing halves during assembly to support the motor within the housing half without the need for the motor to rest on a rib or any other protruding portion of the interior of the housing. The remaining housing half is then secured to the first mentioned housing half such that the motor mounting plate is secured substantially around its entire periphery within the groove formed in each housing half. A bushing insert (62) is included for achieving a tight interference fit between the smooth armature shaft (70) of the motor and a plastic fan member (66). The motor mounting assembly also serves to absorb the force of the "bump" when the operator bumps the line spool of the trimmer against the ground to advance the cutting line.
