[0064] -Construction of end-mounted devices for toothed belts-

[0065] Figure 1 ~ Figure 3 The end attachment tool 1 of the toothed belt according to the first embodiment of the present invention is shown. In the present embodiment, the terminal mounting tool 1 is used to install a jointed toothed belt 50, and a plurality of tooth portions 51 are arranged on the surface of one side of the jointed toothed belt 50 at an equal pitch P (here, For simplicity, it is defined as the upper surface).

[0066] The terminal attachment tool 1 includes a wedge member 2 having a dummy tooth portion (dummy here means that the tooth portion does not operate) 2 a meshing with a tooth portion 51 of the toothed belt 50 . Such as figure 2 As shown, for example, five dummy tooth portions 2 a are arranged at an equal pitch P. Such as Figure 4 and Figure 5 As shown, the wedge member 2 has an inclined slope 2b, the wedge member 2 becomes thinner toward the tip, and is formed of, for example,...

[0086] Figure 8 A second embodiment of the present invention is shown. This second embodiment is different from the above-mentioned first embodiment in that a burring portion 107 is formed. It should be noted that, in the following embodiments, the same symbols are used to represent Figure 1 to Figure 7 The same part as in , the detailed description is omitted.

[0087] That is, if Figure 8 As shown, the flange portion 107 is integrally formed with the top end of the wedge member 102, and the flange portion 107 increases after passing through the belt insertion hole 4 to become a fall-off preventing portion. For example, the top end of the burring portion 107 is divided into two parts. When the wedge member 102 is inserted, the burring portion 107 is easily deformed due to the presence of the notch portion 107a at the left and right central positions. When the wedge member 102 is formed of a resin molded product, the burring portion 107 may be integrally molded with th...

[0095] Figure 11 The third embodiment of the present invention is shown, and the position of the burring portion 207 is different from that of the above-mentioned second embodiment.

[0096] That is to say, in this embodiment, the burring portion 207 is formed on the base end side (higher side) of the wedge member 202, and is cut along the left-right direction to form the notch portion 207a, and the base end of the wedge member 202 The side is easily deformed in the up and down direction.

[0097] The installation part 203 in this embodiment also has an inclined wall 203a. For example, the metal plate is bent and the side wall 203b is slightly opened to form the installation part 203 in this embodiment. The inner cylindrical part 203c formed by bending another metal plate can be inserted into this opening. In this embodiment, the inclined wall 203a, the belt insertion hole 4, and the wedge insertion hole 5 are divided by the inner cylinder portion 203c.

Abstract

Provided is an end fitting mounting device (1) for toothed belts, which is configured so that an end of a toothed belt (50) can be readily and reliably affixed without using a dedicated press device. After the end of the toothed belt (50) is inserted through the belt insertion hole (4) and wedge insertion hole (5) of a mounting member (3), the dummy teeth (2a) of a wedge member (2) are engaged with teeth (51) provided at the end of the toothed belt (50), and the toothed belt (50) with which the wedge member (2) has been engaged is pulled from the direction of the belt insertion hole (4) to affix the wedge member (2) to the mounting member (3).

Description

technical field [0001] The present invention relates to an end mounting tool and a toothed belt end mounting method for mounting an end of a toothed belt having a joint and having teeth on at least one side. Background technique [0002] So far, when a toothed belt that is not jointless or jointed is used for reciprocating drive, etc., it is necessary to fix the two ends of the toothed belt to the fixed member with a certain tension force (such as Patent Document 1) , so it is necessary to use the installation device to fix the two ends of the toothed belt to the fixed parts respectively. The end mounting device in Patent Document 1 installs the toothed belt in such a way that the upper mold and the lower mold have an inner surface that fits with a plurality of teeth of the toothed belt, and the shape of the inner surface is the same as that of the plurality of teeth. Roughly the same, install the upper mold and the lower mold first, and then use these upper and lower molds...
