SOLENOID MOTOR ASSEMBLY FOR A RECIPROCAL MOTOR

摘要

A solenoid motor (10) that has a magnetic housing (12) with a pair of arms (14) that each have a bearing surface. A pair of roller bearings (22) are located between the bearing surfaces and the motor armature (18), such that the armature (18) can move in a linear motion without having to slide against the bearing surfaces of the housing (12). The roller bearings (22) are captured by grooves (20) formed in the armature (18). The housing (12) is constructed so that the arms (14) slightly deflect when the armature (18) and roller bearings (22) are installed, to provide a constantly self correcting bearing assembly. A solenoid (50) produces a magnetic field that moves the armature (18) relative to the housing (12). The motor (10) has a pair of bumpers (44 and 46) that limit the travel of the armature (18). The motion (1) moves an applicator (70) in a reciprocating motion.
