Because it is poor that external gear 26 and internal gear 30 have the small number of teeth, therefore when external gear 26 during owing to the rotary oscillation of eccentric body 20 1 time, just rotate a circle with the engaging position of internal gear 30, external gear 26 is with respect to the internal gear under the stationary state 30, only the amount of dislocation (rotation) and the number of teeth difference of this internal gear 30.The motion of this external gear 26 is, by connect this external gear 26 sold inside the country 42 with being rotatably assorted of interior roller 43, its swing composition is absorbed, only the rotation composition is passed to support unit 34 and output block 36.Be created in the output torque on the output block 36, be passed to the rotary part (not shown) of the object machinery that will drive by bolt hole 46.
Therefore at this, with reference to Fig. 1, Fig. 3, motor M1 is the cylindrical shape near the size of pit 50, at the radially inner side of the summit 54A1～54A4 of the square 54 of motor shell main body 51, has guaranteed bigger space.In the present embodiment, owing in this bigger space, dispose the motor attachment hole 80 that is used to connect this motor shell main body 51 and retarder input side cover (retarder flange) 72, even therefore, also can guarantee enough intensity by 4 bolts that are used to connect motor shell main body 51 and retarder input side cover 72.
In addition, the diagonal distance L4 of the square 74 of retarder input side cover 72, relative edge's distance L 1 than the square 54 of motor shell main body 51 is long a lot, in the space of the suitable position of radial outside of the limit 54S1～54S4 of the square 54 of the motor shell main body 51 of retarder input side cover 72, guarantee to have great space.Therefore, can in this big space, dispose the retarder attachment hole 84 that is used for mechanically installing the mounting hole 82 of retarder G1 and connection reducer shell main body 70 and retarder input side cover 72 at object.Particularly, mounting hole 82 is configured on the position of radially inner side of summit 74A1～74a4 of square 74 of retarder input side cover 72, can only guarantee sufficiently high intensity with 4 bolts.
And, because the relative edge's of the square 74 of the diagonal distance L3 ratio speed reducer of the square 54 of motor shell main body 51 input side cover 72 distance L 2 is little, therefore motor shell main body 51 fully is positioned at the radially inner side of retarder input side cover 72, under the situation of seeing geared motor as a whole, only the square 74 of retarder input side cover 72 constitutes the shape (profile shape do not become star) of profile portion.This profile portion is shaped as foursquare structure, in the time of for example in the driving in the joint (not shown) that this geared motor GM1 is applicable to industrial robot, mean that the structure for the movable range of guaranteeing this joint component biglyyer has very big meaning.This be because, the fitting seat of the retarder of the robot that industry is used (not shown) mostly is quadrangle, the shape of retarder input side cover 72 also is a quadrangle, but, therefore can not damage the freedom of movement (movable range) of robot because reducing gearbox main body 70 is not outstanding from each limit 74S1～74S4 of square 74.By using the geared motor GM1 of present embodiment, the broadnessization of the movable range in the time of can realizing the compactness of geared motor integral body and be applicable to industrial robot.
In addition, in the above-mentioned mode of execution, the shell main body 51 of motor M1 is the square 54 of no-output side cover, retarder input side cover 72 double as motors output side cover.But in the present invention, important is so long as the retarder side end face of motor is polygonal and gets final product, irrelevant with the concrete formation of motor shell.That is, motor shell also can for no-output side cover and shell main body from as polygonal, in addition, also can for have the output side cover and only this output side cover have polygonal flange.
And, in the above-described embodiment, show the input side that the retarder flange is arranged on retarder and cover, but the retarder flange also can be arranged on the main body of shell of retarder.In the case, the input side cover that decelerator-free arranged all can, in addition, but can, also split main body integrated with shell.Axle right angle section for the tube portion of reducing gearbox main body does not require that it is necessary for circle yet, can be for example polygonal section configuration as the square yet.
