A conventional governor drive device will be explained with reference to an exploded perspective view of FIG. 7 is a governor gear case, 4 is a drive gear, 5 is an idler gear, 6 is a timing gear for driving the governor, and 8 is a governor gear case cover. The rotation of the crankshaft of the engine is transmitted to the drive gear 4 through the governor drive timing gear 6 and the idler gear 5, and the rotation of the drive gear 4 drives a governor (not shown).
Engine speed is now controlled.

題点がある。
The engine is used by changing the operating speed according to its specifications, but if the rotation speed deviates from the governor's applicable rotation speed, these gears must be replaced with the governor gear case 7 to change the gear ratio.
It is necessary to change the governor itself to match the applicable rotational speed, which poses a problem in that the number of parts increases and a large amount of cost is required when changing specifications.

ある。 The purpose of the present invention is to solve the problems of the conventional device mentioned above, and to make it possible to share parts including the governor, the link from the governor, the oil supply pipe, etc. for two types of specifications with different engine speeds, and to make it possible to share parts such as the governor, the link from the governor, the oil supply pipe, etc. when changing the above specifications. An object of the present invention is to provide a governor drive device that can reduce the cost of the drive.

The governor drive device of the present invention is characterized in that the center of the support portion that supports the idler gear is arranged eccentrically from the center of the governor gear case mounting pilot. In other words, when the engine is used with two different rotation speed specifications, it is necessary to change the gear ratio of the governor drive timing gear 6 and the governor drive gear 4 in order to be able to use the same governor. However, in this case, the center of the idler gear 4 is arranged eccentrically with respect to the center of the support part,
By eccentrically setting the eccentric portion in the opposite direction, the idler gears 5, 5' and both gear sets 4,
It is possible to mesh with the six-pronged prongs 4' and 6, respectively.

In the above manner, one gear 4 of the two types of drive gears 4 and 4' having different numbers of teeth for the two types of specifications is attached to the governor, while the idler gear 5 attached to the governor gear case 7 drives the governor. Install the governor gear case 7 at an angle that engages the timing gear 6 and drive gear 4, or install the governor gear case 7 at another angle that engages the drive gear 4' and timing gear 6 while attaching another idler gear 4' to the governor. By using a gear mechanism with different gear ratios, it is possible to correspond to two types of specifications with different engine speeds, and it includes not only the governor gear case 7 but also the governor, the link from the governor, the oil supply pipe, etc. Since parts are shared, the cost required for changing the specifications can be reduced.
