Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a gap adjusting collar, and more particularly to a gap adjusting collar for filling a gap between parts in an automatic machine such as a robot.

[0002]

[Prior art]

 Conventionally, in this type of gap adjusting collar, when there is a gap between the bearing member 4 and the gear member 5, as shown in FIG. 3, the movement of the gear member 5 in the central axis direction due to rotational driving is prevented. In order to do so, the ring member 6 located in the gap is arranged between the bearing member 4 and the gear member 5.

A screw hole 6a is provided on the outer periphery of the ring member 6, and an embedded screw (not shown) is screwed into the screw hole 6a, and the bearing member 4 and the gear member 5 are inserted by the embedded screw. The ring member 6 is fixed to a shaft (not shown) that is present.

[0004]

[Problems to be solved by the device]

 In the above-mentioned conventional gap adjustment collar, the one that fits the gap dimension between the parts is selected and placed between the parts. Therefore, if the selected dimension does not match the gap size, it is better than the gap size. There is a problem that a large one must be processed and placed between the parts, and it takes time and labor to obtain the one suitable for the gap size, and the man-hours increase.

Therefore, an object of the present invention is to solve the above problems and to provide a gap adjusting collar which can easily obtain a suitable one for the gap size and can reduce the number of steps.

[0006]

[Means for Solving the Problems]

 The gap adjusting collar according to the present invention comprises a ring member penetrating the shaft and having an inclination of a predetermined angle with respect to the central axis of the shaft.

Another gap adjusting collar according to the present invention is a gap adjusting collar that fills a gap between parts penetrating the shaft and arranged coaxially with the shaft, the collar adjusting collars being arranged on the central axis of the shaft. On the other hand, the first and second ring members each include an inclined surface having an inclination of a predetermined angle, and the inclined surfaces are in contact with each other so that the width in the central axis direction is variable.

[0008]

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings.

1 and 2 are side views of an embodiment of the present invention. In the figure, each of the gap adjusting colors 1 and 2 has inclined surfaces 1b and 2c at a predetermined angle with respect to the central axis of the shaft 3 into which they are penetrated, and normally, the inclined surfaces 1b and 2c are mutually arranged. Abutted.

When there is a gap between the bearing member 4 and the gear member 5 which are respectively penetrated into the shaft 3, the gap adjusting collars 1 and 2 each have the inclined surfaces 1b and 2c in abutment with each other. It is arranged between the material 4 and the gear member 5 (see FIG. 1).

In this state, for example, an embedded screw (not shown) is screwed into the screw hole 1a of the gap adjusting collar 1 and fixed to the shaft 3, and the gap adjusting collar 2 is rotated in the direction of arrow A. Then, the contact surface area where the inclined surfaces 1b and 2c of the gap adjusting collars 1 and 2 contact each other decreases, but the width in the central axis direction formed by the gap adjusting collars 1 and 2 increases. To do.

When the maximum width portions of the gap adjusting collars 1 and 2 are brought into contact with each other, the widths of the gap adjusting collars 1 and 2 in the central axis direction are maximized. In this state, if embedding screws are screwed into the screw holes 2a and 2b of the gap adjusting collar 2 and fixed to the shaft 3, the gap between the bearing member 4 and the gear member 5 will be reduced. Are buried by (see Figure 2).

In the above case, the gap between the bearing member 4 and the gear member 5 is when the width of the gap adjusting collars 1 and 2 in the central axis direction is the maximum. This gap is the gap adjusting collar 1 , 2 within the maximum width in the central axis direction, the widths in the central axis direction of the gap adjusting colors 1 and 2 can be changed according to the gap.

As described above, the gap adjusting collars 1 and 2 are provided with the inclined surfaces 1b and 2c having a predetermined angle, and the inclined surfaces 1b and 2c are brought into contact with each other so as to be interposed between the bearing member 4 and the gear member 5. With the arrangement, at least one of the gap adjusting collars 1 and 2 can be rotated to change the width in the central axis direction.

Therefore, it is not necessary to perform processing in accordance with the gap size as in the conventional example, and the adjustment in accordance with the gap size can be performed in a short time by rotating the gap adjusting collars 1 and 2. Therefore, it is possible to easily obtain a material suitable for the gap size and reduce the number of steps.

In the embodiment of the present invention, the case where there is a gap between the bearing member 4 and the gear member 5 has been described. However, components other than the above arranged on the shaft 3 and components of the apparatus, etc. It is obvious that the present invention can be easily applied even when there is a gap between them, and the present invention is not limited to this.

[0017]

[Effect of device]

 As described above, according to the present invention, two ring members each including an inclined surface having an inclination of a predetermined angle with respect to the central axis of the shaft are abutted to each other and the width in the central axis direction is increased. By making it variable, it is possible to easily obtain the one suitable for the gap size, and it is possible to reduce the number of steps.
