Title:
CONSTANT VELOCITY JOINT FOR PROPELLER SHAFT AND PROPELLER SHAFT
Document Type and Number:
WIPO Patent Application WO/2023/037744
Kind Code:
A1
Abstract:
The present invention is equipped with: an outer race member which has, along the inner circumference of said outer race member, which is formed in a cylindrical shape, an outer race groove section provided so as to recess at an angle to the rotational axis of a constant velocity joint, a first outer race groove end section located on a first propeller shaft side of the outer race groove section, and a second outer race groove end section located on a second propeller shaft side thereof; ball members positioned in the outer race groove section; and an inner race member which has, along the outer circumference of said inner race member, which is connected to the second propeller shaft among the propeller shafts and is provided on the inner-circumferential side of the outer race member, an inner race groove section which is angled relative to the rotational axis of the constant velocity joint, is provided so as to recess so as to intersect the outer race groove section, and is formed in a manner such that the outer diameter thereof is greater than the outer diameter of the second propeller shaft, a first inner race groove end section located on the first propeller shaft side of the inner race groove section, and a second inner race groove end section located on the second propeller shaft side thereof. Therein, the distance from the position in the outer race groove section where a ball member is present to the first outer race groove end section of the outer race groove section is set so as to be greater than the distance from the position in the inner race groove section where a ball member is present to the second inner race groove end section of the inner race groove section.
