Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an installation adjustment device for adjusting the axial center position of a device when the device is installed on an installation stand.

[Prior Art] Generally, when connecting an output shaft of a drive side device and a rotary shaft of a driven side device, it is possible to adjust the position of the shaft center of one shaft to some extent at the installation site. And then
The axes of both shafts are aligned. Conventionally, as a method of installing and adjusting such a device, a shim is inserted between two installation hardwares separated from the axis of the device and an installation base, and the thickness of the shim increases the height of the axis. I was adjusting the height.

Also, if you want to move the axis horizontally to make adjustments,
It is necessary to replace the installation hardware or to make the bolt insertion hole of the installation hardware long in advance. In order to replace the installation hardware, it is necessary to prepare multiple installation hardware. On the other hand, when the long hole is formed, the length of the long hole has a certain limit, and it is necessary to set the tightening force of the bolt to a sufficiently large value to fix the device, which is not preferable.

As another method of installation adjustment, a jack bolt may be used (see Japanese Patent Laid-Open No. 60-222693), but in that case, horizontal adjustment cannot be performed.

The present invention has been made to solve the above-mentioned inconvenience, and it is possible to center the equipment by moving the equipment in both vertical and horizontal directions without the need for shim adjustment or replacement of the installation hardware. Is intended to provide.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a first support in an installation adjustment device for installing an equipment on an installation stand by at least two support portions separated from an axis of the equipment.

Here, in order to move the shaft center 2 of the speed reducer 1 shown in FIG.
As shown in FIG. 6 (a) or FIG. 6 (b), only one of the jacking mechanisms 10A or 10B is operated to first determine the horizontal position of the shaft center 2. Then, the two jacking mechanisms 10A and 10B respectively move the first and third shaft centers 2A and 2C in the vertical direction by the same amount to determine the position of the shaft center 2 in the vertical direction.

As described above, according to the present invention, the speed reducer 1 is installed via the three hinges (first to third shaft centers 2A, 2B, 2C) and the two jacking mechanisms 10A, 10B. Since it is installed on the table 3, the first and second jacking mechanisms 10
The position of the shaft center 2 of the speed reducer 1 can be adjusted by operating A and 10B. Therefore, the speed reducer 1 can be centered without using a conventional shim or installation hardware. In FIG. 6, the shaft center 2 is the first shaft center 2A and the second shaft center.
Although the case of being located on the line connecting 2B has been described, it goes without saying that the axis 2 does not necessarily have to be on the line connecting 2A and 2B.

By the way, the first shaft center 2A or the second shaft center 2B is connected to the speed reducer 1
6 (a) or 6 (b), the shaft center 2 hardly moves in the horizontal direction when the height is set to the same level as the shaft center 2 of FIG. It is preferable to set a level difference between the two axes 2A and 2B.

In the case of the above embodiment, the speed reducer 1 has two support parts 4,5.
However, the number of supporting portions 4 and 5 may be three or more.

Although not shown, a connecting shaft having both ends rotatable and having turn bags is arranged in a direction parallel to the axis 2, and the speed reducer 1 shown in FIG. 1 is provided via the connecting shaft. The upper part of the casing 1a of the above and the base integrated with the installation base 3 are connected, and the shaft body insertion holes 7c of the first bracket 7A and the second bracket 7B are connected to the spherical bearing as shown in FIG. By constructing by inserting 7d, the inclination angle of the speed reducer 1 in the front-back direction of the paper surface of FIG. 1 can be adjusted, and accordingly, the inclination angle of the shaft center 2 of the speed reducer 1 can also be adjusted.

By the way, in the case of the above-mentioned embodiment, in the jacking mechanisms 10A and 10B of FIG. 5, unless the fixing bolt 13 is pulled out,
The pedestals 8A and 8B cannot be moved up and down. On the other hand, as shown in FIG. 7, if the hexagonal column-shaped engaging portion 12c is formed on the bottom of the jacking screw 12, the fixing bolts 13 are simply loosened, and the clearance between the pedestals 8A, 8B and the mounting base 3 is reduced. Jacking screw with a tool such as a spanner inserted horizontally from S
The pedestals 8A and 8B can be moved up and down by rotating 12.

[Advantages of the Invention] As described above, according to the present invention, the position of the device axis can be adjusted by operating the jacking mechanism, so that it is not necessary to replace the shim or the installation hardware.
