Description

BASE ASSEMBLY STRUCTURE OF ACTUATOR}

The present invention relates to a base assembly structure of an actuator, and more particularly, to a base assembly structure of an actuator capable of simultaneously supporting a motor set and a second gear.

The base assembly structure of the conventional actuator has a problem in that the motor set is placed on the base and the intermediate gear is mounted on the lower case, but the intermediate gear is supported only on the lower case, so that the intermediate gear is shaken to cause the intermediate gear to shake. .

The present invention is to overcome the above-mentioned conventional problems, an object of the present invention is to support the motor set as a single base on the upper side, and to support the upper end of the second gear in the lower side, the shaking of the second gear It prevents and improves the degree of bite between the gears.

As an example of the base assembly structure of the actuator according to the present invention,

The upper case and the lower case complete the case, and the motor pinion is engaged with the upper gear of the second gear, and the lower gear of the second gear is in the actuator that is engaged with the output gear.

The two-stage gear is supported through the shaft, and the lower part of the shaft is supported by the shaft insertion part provided in the lower case, and the upper part is supported by the shaft insertion part provided in the lower surface of the base.

The screw is fastened in the order of the screw fastening hole of the plate of the motor set, the screw fastening hole of the base and the screw fastening hole of the boss portion in order, and the assembly of the motor set, the base and the lower case is completed.

The base assembly structure of the actuator according to the present invention is a screw 22, the screw fastening hole 18 of the plate 16 of the motor set 14 and the screw fastener yoke 24 and the boss part 32 of the base 20. The screw fastening hole 33 in order, and the lower part of the shaft 39 of the second gear 72 is supported by the shaft insertion part 38 provided in the lower case 30, and the upper part of the base Since it is supported by the shaft insertion portion 28 provided on the lower surface of 20), it is possible to prevent the shaking of the second-stage gear, there is an effect of improving the degree of debris between gears.

What has been described above is just one embodiment for carrying out the base assembly structure of the actuator according to the present invention, and the present invention is not limited to this embodiment, and as claimed in the following claims, Without departing from the gist of the present invention, one of ordinary skill in the art will have the technical spirit of the present invention to the extent that various modifications can be made.

Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 and 2.

The upper case 12 and the lower case 30 completes the case. Four bosses 32 are provided in the lower case 30, and screw fastening holes 33 are formed in the bosses 32, respectively. On one side of the lower case 30, a bearing insert 41 is formed.

A plate 16 is provided at the lower four corners of the motor set 14, and the screw fastening holes 18 are formed in the plate 16. The motor pinion 70 is mounted to the motor set 14.

The base 20 is seated in the boss portion 32, and a central hole 26 through which the motor pinion 70 can enter and exit is formed at the center thereof, and screw fastening holes 24 are formed at four corners.

The motor pinion 70 meshes with the upper gear of the second gear 72, and the lower gear of the second gear 72 meshes with the output gear 76. The output gear 76 is mounted to the output shaft 50, the output shaft 50 of which the upper part is drawn out through the output shaft outlet 13 of the upper case 12, the lower part of the bearing of the lower case 30 It is withdrawn through the insertion part 41.

The screw 22 fastens the screw fastening holes 18 of the plate 16 of the motor set 14 and the screw fastening holes 24 of the base 20 and the screw fastening holes 33 of the boss portion 32 in this order. do.

Referring to FIG. 2, the second gear 72 is supported by the shaft 39, and the lower portion of the shaft 39 is supported by the shaft insertion portion 38 provided in the lower case 30. Is supported by the shaft insertion portion 28 provided on the bottom surface of the base 20. Therefore, the shaft 39 of the second gear 72 is supported by the shaft insertion portions 28 and 38 both up and down.
