Embodiment 1

[0047] Referring to Figure 1 and figure 2 The first vibration damping type torque transmission mechanism 100 according to the first embodiment of the present invention will be described. As shown in FIG. 1 , this basic vibration damping type torque transmission mechanism 100 has an inner member such as a rotating shaft (hereinafter referred to as a rotating shaft in this embodiment), and an intermediate member that generates a rotating torque between the rotating shaft 1 and the rotating shaft 1. 2 and the outer part 3 of the housing that accommodates the intermediate part 2 without gaps. The intermediate member 2 is composed of three short cylindrical first, second and third torque generators 2A, 2B and 2C and anti-rotation parts 2a, 2b and 2c respectively extending from the torque generators 2A, 2B and 2C.

[0048] Such as figure 2 As shown, the intermediate member 2 is composed of a specific structural member S made of a highly rigid metal material or synthetic resin, and...

Embodiment 2

[0055] refer to Figure 3 ~ Figure 6 The second vibration damping type torque transmission mechanism 200 according to the second embodiment of the present invention will be described. image 3 yes Figure 4 The profile of the dotted line Y-Y', Figure 4 yes image 3 The cross-sectional view of the dotted line X-X'. Figure 5 is a front view of the outer part 3 as the housing, Figure 6 It is a side view of the outer member 3. In addition, in Figure 3 ~ Figure 6 , and Figure 1 and figure 2 The same symbols as used in indicate parts with the same name.

[0056] In Example 2, two coil spring members 12A, 12B are used for the intermediate member 12 that generates rotational torque with the rotating shaft 1 that is an inner member. The coil spring members 12A and 12B are formed by rounding a rectangular metal plate made of a metal material with excellent spring properties to form a press-fit hole P, and the rotary shaft 1 is press-fitted into the partially opened press-fit...

Embodiment 3

[0062] Second, refer to Figure 7 A third vibration damping type torque transmission mechanism 300 according to Embodiment 3 of the present invention will be described. Figure 7 In, with Figure 1~ Figure 6 The same symbols as used in indicate parts with the same name.

[0063] In this embodiment, the rotation shaft 1 and the coil spring 22A of the intermediate member 22 are the same as those of the above embodiments, one end M is open, and the other end N extends in the radial direction of the press-fit hole P. The elastic holding member R3 covers only the rotation stop portion 22a of the coil spring member 22A. The outer surface of the portion that does not cover the coil spring member 22A is in direct contact with the inner wall surface 3i of the outer member 3 that functions as a casing. The elastic holding member R3 surrounding the anti-rotation portion 22a of the coil spring member 22A is in close contact with the inner wall of the anti-rotation housing portion (acco...

Abstract

The present invention provided a vibration damping type torque hinge or a vibration damping type torque limiter formed in a simple and small-sized structure and capable of damping vibration caused by an external force in a short time. This torque transmission mechanism comprises an inside member such as a shaft or an inner ring member, an intermediate member having an inner wall surface producing a torque with the outer surface of the inside member, and an outside member such as a housing having a storage hollow part storing the intermediate member so as not to be rotated. An elasticity holding member formed of an elastic material is installed between the outer surface of the intermediate member and the inner surface of the outside member.

Description

technical field [0001] The present invention relates to a vibration damping type torque transmission mechanism suitable for suppressing vibration applied to a computer monitor or the like. [0002] This application claims priority to Japanese Patent Application No. 2004-160908 filed on May 31, 2004, the contents of which are incorporated herein by reference. Background technique [0003] Torque transmission mechanisms such as torque hinges and torque limiters are generally used in joints such as computers, printers such as OA equipment, and mechanisms for paper feeding, conveying, and discharging of copiers. When the torque hinge or the torque limiter is largely separated, there are a contact mechanism that uses mechanical friction to obtain a desired rotational torque, and a non-contact mechanism that utilizes the magnetic force of a permanent magnet to obtain a desired rotational torque. Currently, torque hinges and torque limiters that are often used are contact mechanis...
