Abstract
In the manufacture of certain stators for dynamoelectric devices, proper spacing between oppositely-facing winding forms of a winding form assembly is determined by the length of a pair of connector rods extending from one winding form to the other. A winding form assembly can be quickly and easily adjusted for use in the manufacture of stators having various stack heights by removal and replacement of the winding form connector rods with connector rods of an appropriate length. The connector rods are locked to one of the winding forms when the connector rods are in a first rotary position and are removable when the connector rods are in a second rotary position. A simple tool can be used to rotate the connector rods between the first rotary position and the second rotary position.
Claims18
A winding form for use in the manufacture of stators for dynamoelectric devices, comprising:
- a winding form body having at least one longitudinally-extending socket formed therein;
- at least one connector rod projecting from said winding form body, one for each socket, each connector rod having an end portion thereof received within its associated socket;
- means associated with each connector rod for retaining the end portion thereof within its associated socket when said each connector rod is in a first rotary position relative to its associated socket;
- and
- means associated with each connector rod permitting the removal of said each connector rod from its associated socket when said each connector rod is rotated to a second rotary position relative to its associated socket.
A winding form for use in the manufacture of stators for dynamoelectric devices, comprising:
- a winding form body having at least one longitudinally-extending cylindrical socket formed therein;
- at least one retainer pin extending within said winding form body, one for each socket, and intersecting its associated socket;
- and
- at least one connector rod projecting from said winding form body, one for each socket and associated retainer pin, each connector rod having an end portion thereof received within its associated socket and having both (a) a relieved portion sufficiently relieved that said end portion can be moved past the associated retainer pin and out of the associated socket when said each connector rod is in a first rotary position relative to its associated socket wherein the relieved portion thereof is in confronting relation to its associated retainer pin and (b) a circumferentially extending groove formed in the end portion thereof opposite said relieved portion that receives the associated retainer pin when said each connector rod is in a second rotary position.
A method for assembling a winding form, said winding form comprising a winding form body and at least one connector rod extending therefrom, said winding form body having at least one longitudinally-extending, cylindrical socket formed therein, one for each connector rod, for receiving a generally cylindrical end portion of its associated connector rod, said method comprising:
- providing at least one retainer pin, one for each socket and associated connector rod, extending within said winding form body and intersecting the associated socket therein;
- providing a relieved portion on the cylindrical end portion of each connector rod, said relieved portion of each connector rod being sufficiently relieved that said end portion can be moved into its associated socket past the associated retainer pin when said each connector rod is in a first rotary position relative to its associated socket wherein the relieved portion thereof is in confronting relation to its associated retainer pin;
- providing a circumferential groove extending around each connector rod opposite the relieved portion thereof;
- with each connector rod in its first rotary position, advancing the end portion of said each connector rod into its associated socket until the circumferential groove in said each connector rod is substantially aligned with its associated retainer pin;
- and
- rotating each connector rod about its longitudinal axis to a second rotary position wherein the circumferential groove in said each connector rod receives its associated retainer pin.
A winding form assembly for use in the manufacture of stators for dynamoelectric devices, comprising:
- a first winding form comprising:
- a winding form body having at least one longitudinally-extending cylindrical socket formed therein,
- at least one retainer pin extending within said winding form, one for each socket, and intersecting its associated socket, and
- at least one connector rod projecting from said winding form body, one for each socket and associated retainer pin, each connector rod having a first end portion thereof received within its associated socket and having both (a) a relieved portion sufficiently relieved that said end portion can be moved past the associated retainer pin and out of the associated socket when said each connector rod is in a first rotary position relative to its associated socket wherein the relieved portion thereof is in confronting relation to its associated retainer pin and (b) a circumferentially extending groove formed in the first end portion thereof opposite said relieved portion that receives the associated retainer pin when said each connector rod is in a second rotary position;
- and
- a second, oppositely-facing winding form comprising a winding form body having at least one longitudinally-extending cylindrical socket formed therein, one for each connector rod, wherein a second, opposite end portion of each connector rod is removably received within the associated socket in said second winding form body.
