Abstract

PURPOSE:To obtain inexpensively a flexible coupling improved in durability and reliability, by connecting a space between a drive side boss component and a driven side boss component through a flexible component consisting of a plurality of pieces of slender leaf springs extending radially. CONSTITUTION:Bores 4B, 5B are formed at the centers of boss components 1, 2 which are to be connected with each other, into which an aligning shaft 6 is inserted rotatably. Disclike enclosures 4, 5 on the external circumferences of which are provided with flanges 4F, 5F protruding in the axial direction are formed unitarily on each of the boss components 1, 2. A plurality of sheets (four sheets in an illustration) of flexible components 3a-3d constituted by cutting out into a U-shaped state from a leaf spring material is arranged radially between these enclosures 4, 5 and both the end parts of each of the flexible components 3a-3d are made to stick on the end parts of connecting sides of the respective boss components 1, 2. With this construction, both the boss components 1, 2 are connected flexibly through the flexible components 3a-3d with each other.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a flexible joint K, more specifically, for flexibly connecting the end of a drive shaft to the end of a passive shaft coaxially arranged therewith. Concerning fittings.

The present invention relates to improvements to conventional flexible joints.

The objective is to obtain an economical flexible joint with improved durability and reliability by using a leaf spring as the flexible element.

According to the present invention, the driving side boss member and the passive side boss member are coaxially arranged with their respective end faces facing each other;
The outer peripheral ICs of the driving side boss member are arranged radially, one end of each IC is fixed to the driving side boss member, and the opposite end extending beyond the above two end faces toward the driven side boss member is fixed to the driven side boss member. A flexible joint member comprising a plurality of elongated leaf springs is provided.

Now, an embodiment of the apparatus of the present invention will be described below with reference to the accompanying drawings.

As shown in Fig. 1, the simplest form of the burnable joint 10 according to the present invention has a driving side boss side work and a passive side boss arranged coaxially with their respective ends IK and 2E facing each other. The member 2 is provided.

A distance d of 7t is provided between both end faces IE and 2E. The drive side boss member 1 is connected to a drive shaft such as the output shaft of a prime mover (not shown), and the passive side boss member 2 is connected to a passive shaft such as an axle (not shown) to which a car wheel is attached. be done. The device 10 of the present invention further includes a drive side boss member 1.
A readable member consisting of a plurality of thin leaf springs (four in the figure) with a frame passing between the part adjacent to the end IE of the passive boss member 2 and the part adjacent to the end 2E of the passive boss member 2. 3a,,36
, 3c, and 3d. As shown in Figure 1(b), four readable members 3a, 36, 3c and 3d are arranged radially at equal intervals around the outer periphery of the drive-side boss member l, parallel to the central axis XXK of both boss members. extends to Each flexible member has its left end in contact with the outer periphery of the drive-side boss member 1 and its right end in contact with the outer periphery of the driven-side boss member 2. Therefore, when the driving side boss member 1 transmits torque to the driven side boss member 2, each readable member 3a.

3b, 3t? , 3dlt”L deflection, passive side boss member 2V
C Prevent impact from being applied.

Figures 2α, 2b and 2C show an embodiment of the device of Figures j and 1, in which both boss members 1 and 2 are provided with coaxial bores 4B and 5B, respectively, and the alignment 1llllI6 is connected to these bores. It is rotatably inserted into 4B and 5B. The flexible members 3α, 36, 3c and 4d are composed of U-shaped leaf springs (Fig. 2α).

The drive side boss member 1 has a disk shape 4 extending from the left end.
, and the outer periphery of the frame 4 (() is provided with a tubular flange 4F concentric to the drive side post member l, and the flexible members 3a, 3b, 3c
, 3d so as to almost cover the left half of the area. Similarly, the passive side boss member 2 is also provided with a disk-shaped shield 5 that extends from the right side in a disk shape, and on the outer periphery of the shield 5 is a tubular 7-land 5F.
is provided so as to cover the left half portions of the burnable members 3a, 3b, 3c and 3d.

The spears 3a, 2b and 30 differ from those shown in FIG. 2α in that they have a W-shaped configuration similar to the devices shown in FIGS. 3-2a and 2b (FIG. 3α).

Axis 4 (Figures Z and 4b show another modification of the embodiment shown in Figures 2α and 2b, with a driving side boss member 1 and a driven side boss member 2.
Several intermediate boss members 9 are placed coaxially between the drive-side boss member l and the intermediate boss member 9, and flexible members 3a, 34.3c, and 3d of a group of four members are mounted between the drive-side boss member l and the intermediate boss member 9. is handed over, and the flexible members 8α, 8b, F3c, 8tl of 2.2# consisting of four sheets are passed.
However, a frame is provided between the intermediate boss member 9 and the passive boss member 2.

The flexible members 8α, 3b, 3C, and 3d of the 2nd group of teeth are different from the flexible members 3ct, 3h, 3C, and 3d of the 1st group by 45 degrees.
The positions are different. The modified embodiment of Fig. 4α is shown in Fig. 2α.
Figures 5α and 5b correspond to two flexible joints arranged in tandem and joined together with the mounting positions of the flexible members of both flexible joints differing by 45 degrees. This shows another embodiment of the device, in which the drive-side boss member l is oriented in the axial direction
XVc is lengthened, and the length 4 in the axial direction XX of the tubular flange 5F that extends from the outer periphery of the enclosure 5 provided on the left side of the driven side boss member 2 toward the outer periphery of the enclosure 4 of the driving side boss member 1 is increased. Four flexible members 110. , i 1 b ,
11'+11i extends the opposite end in the radial direction and disengages from the inner surface of the tubular flange 5F. The embodiment shown in FIG. 5α is advantageous in making the entire flexible joint compact.

3□ 617α and 76 show an embodiment in which the device of the present invention is used as a torsion meter. That is, scales B and B' are engraved on the outer periphery of the end of the tubular flange 5F extending from the bracket 5 of the driven side boss member 2 of the flexible joint 10, and the scales B and B' are engraved on the outer periphery of the end of the tubular flange 5F extending from the bracket 5 of the driven side boss member 2 of the flexible joint 10. An indicator A is engraved on the outer periphery of the end of the tubular flange 4F. When there is no load, index A matches scale B, but when load is applied, point B moves to B'. By measuring the distance between point B and point F, the shaft horsepower can be determined. As shown in Figures 7α and 7b, when measuring the distance between points B and B', magnetic points 12.1 are placed at each of these points.
3 and rotate the flexible joint 10 to measure the time when each of the two magnetic points 12 and 13 passes under the detection mechanism 14.

As described above, according to the present invention, by using a leaf spring as a flexible element, a reliable and durable flexible joint can be manufactured at low cost.
