Abstract
Official abstract text for this publication.
A resolver has a structure in which the resolver is attached to a flange by press-fitting and in which strong stress that affects an angle detecting accuracy of a stator of the resolver is not applied. The flange, in which a resolver is press-fitted, includes a cylindrical portion in which a stator of the resolver is press-fitted to the inside thereof, and a tabular portion which is larger than an outer diameter of a cylindrical portion viewed from an axial direction and which is integrated with the cylindrical portion, wherein a clearance portion having an expanded inner diameter which does not contact with an outer periphery of the stator of the resolver is provided on an overlapped portion of a cylindrical portion viewed from a vertical direction to the axis and the tabular portion.
First claim
Opening claim text (preview).
What is claimed is: 1. A resolver assembly, comprising: a resolver having a stator; and a flange in which the resolver is contained, the flange comprising: a cylindrical portion in which the stator is press-fitted to the inside thereof, and a tabular portion that is greater than an outer diameter of the cylindrical portion viewed from an axial direction and that is integrated with the cylindrical portion, wherein a clearance portion having an expanded inner diameter that does not contact with an outer periphery of the stator is provided on an overlapped portion of the cylindrical portion viewed from a vertical direction to the axial direction and the tabular portion, and a length in an axial direction of the clearance portion is greater than a thickness of the tabular portion. 2. The resolver assembly according to claim 1 , wherein a chamfered guide portion is formed on an inner periphery of an opposite end of the cylindrical portion to a portion in which the clearance portion is provided. 3. The resolver assembly according to claim 1 , wherein the clearance portion has a tapered shape in which an inner diameter gradually decreases in an extending direction of the cylindrical portion. 4. The resolver assembly according to claim 1 , wherein the clearance portion has a round surface shape. 5. The resolver assembly according to claim 1 , wherein the clearance portion has an enlarged diameter structure in which an inner diameter is a fixed value in an extending direction of the cylindrical portion.
