Description

[Detailed Description of the Invention] The present invention relates to a rotating equipment mounting device that is advantageous for attaching an hour meter or the like (rotating equipment) for displaying the operating time to a construction machine, for example. be.

For example, the conventional means of attaching an hour meter to a construction machine is as shown in FIG. 1, in which an hour meter 1 is provided with a protruding stem 2 having a thread carved on its outer periphery, and a driven rotating shaft 3 is located in the center of the stem. , on the other hand, the main body 4 of the construction machine has
A stem 6 with a drive rotation shaft 5 passing through the center and a thread carved on the outer periphery is integrally provided, and both stems 2, 6
are engaged and connected by a union nut 7, and the driven rotation shaft and the drive rotation shaft 5 are engaged and connected.
The screws cut into both stems 2 and 6 are formed with opposite pitches, so that the hour meter can be attached without rotating the hour meter.

However, the hour meter 1 is supported by one hand on the main body 4 via a union nut 7, and since the connecting support part of the hour meter 1 is located eccentrically from the center of gravity of the hour meter, it is difficult to operate the construction machine. There was an inconvenience that the union nut loosened when vibrations were generated.

This invention eliminates the loosening of the conventional union nut,
The present invention provides a rotating equipment mounting device that connects and holds a rotating machine body in a stable state at all times.

In other words, the reason why the union nut loosens in the conventional example above is
Focusing on the fact that rotational force around the driven rotating shaft acts on the hour meter due to vibrations, etc., the present invention is equipped with a mechanism that can block this rotational force of the hour meter, thereby overcoming the conventional drawbacks. It is to wipe out.

The present invention will be explained in detail below based on the embodiment shown in FIG.

Reference numeral 2 denotes a stem protruding from the side surface of the hour meter, and a screw 2b for engaging a union nut 7 similar to that of the conventional example is cut on the outer periphery of the stem 2.

The distal end surface of the stem 2 is formed with a semicircular second surface 2c having a notch surface 2a in the diametrical direction.

Reference numeral 6 denotes a stem protruding from the side surface of the main body to which the hour meter is to be fixed, and a screw 6b for engaging a union nut 7 similar to the conventional example described above on the outer periphery of this stem 6.
is engraved therein, and the distal end surface of the stem 6 is formed with one semicircular next surface 6c having a notch surface 6a in the diametrical direction.

Note that 3 is a driven rotating shaft located at the center of the stem 2, and 5 is a driving rotating shaft located at the center of the stem 6.

As described above, the stems 2 and 6 having the diametrical notch surfaces 2a and 6a are brought into contact with each other, and both of the notch surfaces 2a are
By tightening the union nut (7) with and (6a) aligned, both stems are connected, and the driven rotation shaft 3 and drive rotation shaft 5 are securely connected.

That is, when both stems 2 and 6 are connected with the union nut I, the cutout surface 2a provided on the stem 2 comes into contact with the cutout surface 6a provided on the stem 6, and rotation of the stem 2 is prevented. Even if vibration is applied to, for example, an hour meter having the stem 2, the stem 6, that is, the hour meter, does not rotate, and therefore, the union nut I maintains a strong connection between the two stems without loosening the connection. It has the effect of
