Method of producing machines having proper freedom of revolution for rotatable assemblies therein

Claim 1

A METHOD OF MANUFACTURING AN ELECTRIC MOTOR INCLUDING A STATIONARY ASSEMBLY INCLUDING A STATOR CORE, A ROTATABLE ASSEMBLY HAVING A MAGNETIC CORE SECURED TO REVOLVE WITH A SHAFT, AND A THRUST TRANSMITTING MEANS LOCATED ON EITHER SIDE OF THE CORE, AND A PAIR OF JOURNAL BEARING MEANS EACH FORMED WITH A BORE ROTATABLY SUPPORTING THE ASSEMBLIES FOR RELATIVE ROTATIVE, THE METHOD COMPRISING THE STEPS OF: FASTENING THE ASSEMBLIES IN A FIXED RELATION, WITH AN AIR GAP OF PREDETERMINED DIMENSIONS BEING FIXEDLY FORMED BETWEEN THE CORES, AND WITH ONE THRUST TRANSMITTING MEANS FACING AWAY FROM EITHER SIDE FACE OF THE CORE OF THE ROTATABLE ASSEMBLY IN SPACED RELATION THEREWITH AT A FIRST PRESELECTED AXIAL POSITION RELATIVE TO CORE, SLIDING THE JOURNAL BEARING MEANS ONTO ASSOCIATED SHAFT JOURNALS AND BIASING THE JOURNAL BEARING MEANS INTO ENGAGEMENT WITH THE ASSOCIATED THRUST TRANSMITTING MEANS; PIVOTALLY SUPPORTING EACH JOURNAL BEARING MEANS FOR ANGULAR MOVEMENT IN TWO SEPARATE DIRECTIONS, AS THE JOURNAL BEARING MEANS IN TURN SUPPORT THE COMBINED WEIGHT OF THE STATIONARY AND ROTATABLE ASSEMBLIES WHEREBY THE COMBINED WEIGHT OF SAID ASSEMBLIES CAUSES THE JOURNAL BEARING MEANS BORES TO PIVOT INTO ALIGNMENT WITH THE ASSOCIATED JOURNAL OF THE SHAFT; SECURING EACH OF SAID JOURNAL BEARING MEANS AND SAID STATIONARY ASSEMBLY TOGETHER AS BOTH OF SAID JOURNAL BEARING MEANS ARE BEING BIASED TOWARD THE ASSOCIATED THRUST TRANSMITTING MEANS WHILE CARRYING THE COMBINED WEIGHT OF SAID ASSEMBLIES AND AS SAID PRESELECTED AXIAL POSITIONS OF SAID THRUST TRANSMITTING MEANS ARE BEING MAINTAINED AT SAID PRESELECTED AXIAL POSITIONS; RELEASING SAID STATIONARY AND ROTATABLE ASSEMBLIES FOR RELATIVE ROTATION; AND CHANGING AT LEAST ONE OF SAID THRUST TRANSMITTING MEANS FOR THE FIRST TO A SECOND PERSELECTED AXIAL POSITION LOCATED NEARER SAID MAGNETIC CORE OF THE ROTATABLE ASSEMBLY THAN THE FIRST TO PROVIDE THE DESIRED TOTAL END PLAY FOR THE ROTATABLE ASSEMBLY IN THE MOTOR.
