Abstract

PURPOSE:To adjust angular displacement simply and surely by sandwiching a pair of inclined discs having fine inclination equal to opposite face and display of the direction of inclination and rotatable in the circumferential direction against the coupling main body between the coupling main bodies combined together by means of reamer bolts and nuts. CONSTITUTION:Two coupling main bodies 1 fixed on shafts 2 with lock nuts 3 are combined together with reamer bolts 4 and nuts 5. At this time, a pair of inclined discs 6 are sandwiched between both coupling main bodies 1. The inclined discs 6 are provided with equal fine inclination on the mutually contacted faces and display of the direction of inclination on the outer circumference. By relatively rotating the pair of inclined discs 6 in the circumferential direction, an optional angular displacement can be given between the flanges of the coupling main bodies 1, 1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for adjusting an angular displacement of a joint main body flange surface in a flange type fixed shaft joint.

[0002]

[Prior Art] Conventional flange type fixed shaft joint is JIS B1451
-As described in 1986, the angular displacement adjustment device for the joint flange surface is not installed.

[0003]

The prior art does not consider adjustment of angular displacement caused by shrink fitting or press-fitting of the joint flange surface to the shaft, and for equipment that requires high-precision centering. After mounting the joint body on the shaft, machine the flange surface at a right angle to the shaft center, or adjust the angular displacement of the flange surface by sandwiching a non-parallel secondary machined spacer between the joint body flange surfaces. However, there is a problem in that adjustment of the angular displacement becomes complicated.

SUMMARY OF THE INVENTION An object of the present invention is to provide a flange type fixed shaft joint which can easily and surely obtain an arbitrary minute angle adjustment amount and direction without machining the angular displacement adjustment of the joint body flange surface. .

[0005]

In order to achieve the above object, the present invention connects two axes by sandwiching a pair of discs having a slight inclination angle between the joint body flange surfaces.

Further, an equal division mark is provided on the outer circumference of the disc so that the inclination direction of one disc with respect to the joint body and the other disc can be confirmed.

Further, the disc is rotatable with respect to the joint body so that the inclination direction can be oriented in any direction.

[0008]

The function of the present invention is to connect the joint with the reamer bolt at a position where a pair of discs having a slight inclination angle between the joint body flange surfaces are rotated in the circumferential direction, and thereby to connect the joint body flange surface in any direction. To, an arbitrary minute angular displacement amount is given.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 shows a vertical sectional view of a flange type fixed shaft joint of the present invention. FIG. 2 shows a developed view of the outer peripheral surface of the inclined disk of FIG.

Reference numeral 1 is a joint body, 2 is a shaft, 3 is a lock nut, 4 is a reamer bolt, 5 is a nut, and 6 is an inclined disc.

The joint body 1 is fixed to the shaft 2 by a lock nut 2, and the joint body 1 is joined by a reamer bolt 4 and a nut 5 with an inclined disc 6 sandwiched between the flange surfaces of the joint body 1.

On the outer circumference of the inclined disc 6, an indication 7 of the inclination direction is displayed.

[0014]

According to the present invention, since it is possible to give an arbitrary minute angular displacement amount to an arbitrary direction on the joint body flange surface, it is not necessary to adjust the angular displacement by the secondary processing of the flange surface and the spacer. Therefore, the centering adjustment at the time of connecting the shaft coupling can be simplified.
