Description

[Detailed Description of the Invention] The present invention relates to an improvement in a shim used when assembling gears in various gear cases and adjusting the balance between gears and tooth contact.

Conventionally, when adjusting the backlash and tooth contact of the pinion 3 on the pinion shaft 2 in the gear case 1 and the bevel gear 5 on the bevel gear shaft 4 in assembling the side drive type tillage rotary device shown in FIG. This adjustment is made by interposing several shims 7 of different thicknesses between the joint surfaces of the gear case 1 and the gear case 1.

However, even though the shims 7 used here have different thicknesses, they are all the same in shape and diameter as shown in Figure 2, so it is not only difficult to distinguish between them, but also difficult to pick and adjust the shims. This was a major cause of trouble.

The present invention aims to improve the above-mentioned drawbacks of the conventional shim and provide a shim that is easy to pick and that makes it easy to distinguish between the two even if the thicknesses are similar. A plurality of shim bodies with different thicknesses are provided in the thickness direction, and the outer edge of each shim body has a position in the longitudinal direction of the outer edge with respect to the corresponding positioning part that is different between the shim bodies with different thicknesses. The main feature is that it has a knob that protrudes outward.

To explain the embodiment of the present invention based on the drawings, in Figs. 3 and 4, 8 is Q, a 5 mm thick shim body, 9 is Q
, 3 mm thick shim bodies, and 10 are 0.1 mm thick shim bodies, and the outer edges of each of these shim bodies 8, 9, 10 are integrally provided with knob pieces 11, 12, 13 that protrude outward. It is set up.

Each of the knob pieces 11, 12, 13 is arranged such that the position in the longitudinal direction of the outer edge with respect to the corresponding positioning part, for example, the corresponding bolt passage part 15 in the embodiment, is different from each other, so that each shim body 8. Even when 9.10 are overlapped in the thickness direction with their respective bolt passages 15 aligned,
Each of the knob pieces 11, 12, and 13 is always at a position shifted in the longitudinal direction of the outer edge.

When the shim is configured in this way, by having each knob, it is easy to insert and remove the shim at a desired location, for example, between the joint surfaces of the gear case 1 and the bearing case 6, and when the shim is inserted at that location. Since the position of each picking piece is different, it is possible to obtain the effect that it is easy to pick out the desired shim body.

In addition, as shown in the figure, the shim body of each thickness above is divided into two parts,
In addition, if a bolt passage portion 15 through which the bolt 14 is passed is cut out at each inner peripheral edge and the separated end, for example, the bolt 14 can be inserted between the joint surfaces of the gear case 1 and the bearing case 6 in advance.
4 is passed through, it is convenient because each shim body can be taken in and out from the diametrical direction between the joint surfaces.

As described above, according to the present invention, a plurality of shim bodies having different thicknesses are provided in the thickness direction, and the outer edge portion of each shim body has a position in the molecular direction relative to the corresponding positioning portion. Since the tab pieces that protrude outward are provided so that the shim bodies have different thicknesses, it is easy to distinguish between the shim bodies of different thicknesses when they are installed, and the shim bodies can be easily picked up. This allows for extremely easy shim adjustment.
