Problems solved by technology

[0007] However, in the configuration described in Patent Document 1, although the phases of the mutually meshing gears can be aligned, it is difficult to align the phases of the gears connected via other gears.
In addition, in the case of protrusions and recesses formed by missing teeth, if the gear has a small number of teeth, the meshing ratio will be low, so there is a problem of failure during rotation.

other Embodiment approach

[0100] In the above embodiment, although the stopper 8 is provided on the input gear (gear 61 ), it may be provided on other gears 62 , 63 and the like.

[0101] In the above-mentioned embodiment, the stopper 8 is arranged on the gear mechanism 6 of the geared motor 1 with the motor 2 as the driving source, but the present invention can also be applied to the arrangement of the stopper 8 on the gear mechanism 6 driven by the motor 2 . The case on the gear mechanism 6 of the device other than the geared motor 1 of the source.

[0102] In the above-mentioned embodiment, on the stopper 8, the protruding part 617a is provided on two parts separated in the circumferential direction, and the recessed part 617b is provided on each of the protruding parts 617a at the two parts, but it is also possible A structure in which a continuous recess 617b is formed between the protrusions 617a provided at two locations is employed.

[0103] In the above embodiment, the first hole 649 and the ...

Abstract

Geared motor and manufacturing method thereof. In the geared motor, the phase between the gears which are not engaged with each other directly is capable of being matched. When a gear mechanism (6) is to be assembled, a first hole (649) is preformed on an output member (640), and a second hole (619) is preformed on a gear (61). The position where the first hole (649) is fitted to a first pin (91) is set as an assembling angular position of the output member (640). The position where the second hole (619) is fitted to a second pin (92) is set as an assembling angular position of the the gear (61). A gear (63) is disposed in a manner that the gear (63) is fitted to a fulcrum shaft (73), and the gear (63) is engaged with the output member (640). In addition, a gear (62) is disposed in a manner that the gear (62) is fitted to a fulcrum shaft (72), and the gear (62) is engaged with the gear (63). Additionally, the second hole (619) is formed in an elliptic shape or an oval shape and thus, in a state that the second pin (92) is fitted into the second hole (619), the gear (62) and the gear (61) are engaged while an angular position of the gear (61) is finely adjusted.

Description

technical field [0001] The invention relates to a geared motor including a motor and a gear mechanism and a manufacturing method thereof. Background technique [0002] A geared motor has a motor and a gear mechanism that transmits the rotation of the motor. In the above gear mechanism, as a structure for aligning the phases of the gears, it has been proposed to provide a convex portion formed by missing teeth on one gear, The other gear has a structure in which a concave portion formed by missing teeth is provided (refer to Patent Document 1). [0003] According to the above configuration, the phases of the gears can be aligned with each other based on the convex portion provided on one gear and the concave portion provided on the other gear. [0004] prior art literature [0005] patent documents [0006] Patent Document 1: Japanese Patent Laid-Open No. 2009-2422 [0007] However, in the configuration described in Patent Document 1, although the phases of the mutually m...
