Motor manufacturing method, motor

Abstract

Provided is a motor manufacturing method including: a step for accommodating a stator in a case; a step for inserting a stick-like fixing member through a through-hole formed in the stator and an annular part of a collar member having the annular part, which is formed in an annular manner, and a claw part extending in a radial direction of the annular part; a step for determining the position of the stator with respect to the case by bringing a distal end of the claw part into contact with an inner surface of the case; and a step for tightening the fixing member so as to move along the axial direction, thereby deforming the claw part and fixing the stator with respect to the case. When the stator is fixed to the case by means of the fixing member, the claw part is in a state of being not in contact with the inner surface of the case.

Claims

1. The steps include housing the stator in the case, A step of inserting a rod-shaped fixing member into the annular portion, the cylindrical portion, and the stator of a collar member having an annular portion formed in an annular shape, a claw portion extending radially in the annular portion, and a cylindrical portion connected to the annular portion and extending in the direction of the central axis of the annular portion; The steps include: fitting the cylindrical portion into the inner circumferential surface of the through hole and bringing the tip of the claw portion into contact with the inner surface of the case to determine the position of the stator relative to the case; The steps include tightening the fixing member so as to move it along the axial direction, thereby deforming the claw portion and fixing the stator to the case, Includes, A method for manufacturing a motor, wherein when the stator is fixed to the case by the fixing member, the claw portion does not come into contact with the inner surface of the case.

2. The method for manufacturing a motor according to claim 1, wherein the claw portion is a portion of the outer circumference of the annular portion that protrudes radially outward more than other portions.

3. At one end of the fixing member in the axial direction, a head is formed which has a larger outer diameter than the other parts of the fixing member in the axial direction. A base portion is formed in the opening of the through hole in the stator to receive the head of the fixing member. The motor manufacturing method according to claim 1 or 2, wherein in the step of fixing the stator, the head of the fixing member is tightened so as to press against the base portion via the collar member, thereby deforming the claw portion located between the head and the base portion.

4. The base portion has an inclined surface that is inclined with respect to a reference plane which is a plane perpendicular to the central axis of the through hole. In the step of determining the position of the stator, the claw portion extends along the reference plane, so that the tip of the claw portion contacts the inner surface of the case. The motor manufacturing method according to claim 3, wherein in the step of fixing the stator, the claw portion is pressed against the slope by the head, causing the claw portion to deform into a shape that extends along the slope, and the tip of the claw portion separates from the inner surface of the case.

5. Stator and, The case in which the stator is housed, A fixing member formed in a rod shape, which fixes the stator to the case, Color components, Equipped with, The aforementioned color member is The annular part formed in a ring shape, The claw portion extending from the annular portion, A cylindrical portion connected to the annular portion and extending in the direction of the central axis of the annular portion, It has, The cylindrical portion is fitted to the inner circumferential surface of the through hole formed in the stator. The fixing member is inserted through the annular portion and the cylindrical portion of the collar member, and is also inserted through the through hole. The stator is spaced apart from the inner surface of the case in the radial direction of the stator. A motor in which the length of the claw portion along its extending direction is equal to the distance between the annular portion and the inner surface of the case, and the claw portion does not come into contact with the inner surface of the case.

6. The steps include housing the stator in the case, A step of inserting a rod-shaped fixing member through the annular portion of a collar member having an annular portion formed in a ring shape and a claw portion extending radially in the annular portion, and through a through hole formed in the stator, The steps include: fitting the fixing member to the inner surface of the annular portion and the inner surface of the through hole, and bringing the tip of the claw portion into contact with the inner surface of the case to determine the position of the stator relative to the case; The steps include tightening the fixing member so as to move it along the axial direction, thereby deforming the claw portion and fixing the stator to the case, Includes, A method for manufacturing a motor, wherein when the stator is fixed to the case by the fixing member, the claw portion does not come into contact with the inner surface of the case.
