Embodiment Construction

[0047] The implementation of the rotary shaft joint of the present invention will be described below with reference to FIGS. 1 to 15 .

[0048] 1 to 4 show a first embodiment of the rotary shaft joint of the present invention.

[0049] The rotary shaft joint 1 of the first embodiment, as shown in each figure, is composed of a pair of joint half bodies 2a, 2a, 2b and has a gear with 8 teeth.

[0050] Specifically, each joint half body 2a, 2b forms a hub portion 4a, 4b on the central portion of the disc-shaped main body 3a, 3b, respectively, and forms a central hole 5a, 5b in the hub portion 4a, 4b, and its rectangular shape The cross-section is spline-fitted with the shaft ends 12a, 12b having a rectangular cross-section in the rotating shafts 11a, 11b. On the opposite faces of each main body 3a, 3b of each joint half body 2a, 2b, one is provided with the external teeth 6a of a gear with 8 teeth, and the other is provided with a gear meshing with the external teeth 6a and hav...

Abstract

A rotary shaft coupling is provided that can accurately transmit rotation of one rotation axis to another rotation axis even when shaft core misalignment is present between the rotation axes, and has superior durability, without generating noise. In a rotary shaft coupling 1 including a pair of joint halves 2a and 2b that are respectively attached to opposing axial end sections 12a and 12b and transmit rotation of one axis 11a to another axis 11b, outer teeth 6a of a gear are provided on one joint half 2a and inner teeth 6b that mesh with the outer teeth 6a and have a same number of teeth as the outer teeth 6a are provided on the other joint half 2b. Each outer tooth 6a and each inner tooth 6b are formed to absorb shaft core misalignment between both axes 11a and 11b and perform rotation transmission by having an involuted tooth profile of a same module and a tooth flank of the involuted tooth profile displaced in a circumferential direction.

Description

technical field [0001] The present invention relates to rotary shaft joints, and more particularly to rotary shaft joints suitable for transmitting rotation between rotary shafts with opposite shaft ends. Background technique [0002] Generally, in order to smoothly transmit the rotation between the shaft centers that may be staggered relative to each other, a shaft joint is used. [0003] Conventional methods of using flexible joints for rotating shaft joints have the following problems: a large number of parts, heavy weight, uneven rotation during rotational transmission, and high manufacturing costs. [0004] Therefore, there has been proposed a rotary shaft joint that has a pair of joints of the same shape in which concave and convex portions are equally divided on the circumference of a disc-shaped base with the rotary shaft fixed at the center, and the concave and convex portions are made to face each other in phase. meshing with each other.
