摘要： A rotary driving apparatus including internally-meshing planetary reduction gear to which the output rotation of a motor is inputted, a drive shaft to which the output rotation of the planetary reduction gear is transmitted, an output rotary shaft to which the rotation of the drive shaft is transmitted, and a rotary flange provided on the output rotary shaft with a wheel mounted on the flange. The speed of the output rotation of the motor is reduced and then transmitted to the wheel so as to cause a vehicle to run on the wheel. The apparatus further includes a free-wheel mechanism comprising first axially-slidable engagement means provided between the drive shaft and an external gear of the planetary reduction gear, second axially-slidable engagement means provided between the drive shaft and the output rotary shaft, an operational shaft which is arranged to be fixed to an end portion of the drive shaft and which is slidable axially and capable of being fixed at an axial position, a guide in which the operational shaft is guided, and means for permitting the operational shaft to slide axially. When the operational shaft is slid axially, at least the engagement between the drive shaft and the external gear is either established or interrupted.

摘要： In an inscribed meshing planetary gear construction provided with a carrier pin (a carrier member) 116, rigidity and stability are improved and its entire length is shortened, resulting in that in particular, the connection between an input shaft 101 and an eccentric body 103 can be improved so as to reduce the number of component parts and the number of assembling steps. In order to realize this object, a flange part 114 of an output shaft 102, a carrier pin 116 and a support ring 117 are supported at both ends by a pair of bearings 115a and 115b, and then a reduction gear mechanism is disposed between bearings 115a and 115b. The input shaft 101 is formed with a D-cut part of cross section by cutting a part of its outer circumference in parallel with its axial direction. This cut part is utilized so as to set a circumferential position (a stop of rotation) between the input shaft 101 and an eccentric body 103. A carrier pin 116 has a pipe-like spacer 125 at its central part, the axial position of the flange part 114, the carrier pin 116 and the support ring 117 is set through a spacer 125.

摘要： In a variable speed geared motor constructed by combining an inverter motor controllable in rotational speed by inverter drive with a gear reducer, the gear reducer is of a two-stage type, and a reduction ratio i of the gear reducer is suppressed so that i.ltoreq.N holds where N stands for a maximum reduction ratio of the inverter motor at which a constant torque characteristic can be ensured. Further, in a series of variable speed geared motors each satisfying the above conditions, a common ratio R of a series of reduction ratios i of the variable speed geared motors is set to 1.2-1.5. For example, the series is set to 2, 3, 4, 5, 6, and 8.Accordingly, the geared motor can be constructed lightly in weight, compactly, and at low costs, and it can be economically used in a rotational speed region of 200-900 rpm which is an ordinary region in driving of a pump or a high-speed conveyor.

摘要： In fabricating an inner roller for use in an internal-meshing planetary gear construction, the outer periphery of an inner-roller blank 30c is chucked in the state in which depressive forces are equally exerted on the outer periphery in all the directions thereof by a chucking jig 50A, and the inner-peripheral wall of the blank 30c is subjected to a burnishing work in this state. The resulting inner-roller blank 30c is heat-treated in the state in which the depressive chucking is released, whereupon the outer periphery of the blank 30c is finished by grinding. It is accordingly possible to fabricate at low cost the inner roller which can suppress angular backlash owing to a smaller clearance defined between it and a mating inner pin, and which exhibits a high durability and favorable slip characteristics.

摘要： An inner roller 30 (in FIG. 2) for use in an internal-meshing planetary gear construction has its inner-peripheral wall 32 formed into a shape which is brought closer to a regular polygon of n sides (where n denotes an integer of at least 3, and n=3 holds in the illustrated example). Lubricating oil is reserved in clearances H1 defined near the vertices of the regular triangle, and an inner pin 7 is retained in light touch with the three middle points P1-P3 of the respective sides of the regular triangle. Thus, the reservation of the lubricating oil and the retention of the inner pin 7 free from backlash are made consistent, thereby to relieve the backlash of the planetary gear construction and to enhance the durability thereof. The shape of the inner-peripheral wall 32 closer to the regular polygon of n 7 is obtained in such a way that the inner-peripheral wall 32 is subjected to a burnishing work in the state in which depressive forces (deforming forces) based on chucking jigs are applied to the circumferential equidistant positions of the cylindrical blank of the inner roller 30, and that strains (residual strains) remaining after the burnishing work are further enlarged by a heat treatment.

摘要： A clutch mechanism in a gear transmission. A first gear is fixed to one of input and output shaft disposed in parallel with each other, while a second gear engaging with the first gear is fitted on the other. The second gear is rotatable and axially slidable relative to the other shaft, and two groups of splines are formed in the fitting surfaces of the second gear and the other shaft and are capable of engaging with and disengaging from each other in response to the axial sliding of the second gear. With this mechanism, the transmission of rotation of the input shaft to the output shaft is established and interrupted by axially moving the second gear. Also disclosed is another clutch mechanism in a gear transmission. A second gear is loosely fitted on the other shaft, while a third gear is fitted on the other shaft in such a manner as to be prevented from rotating relative to the other shaft but be axially slidable relative thereto. With this mechanism, the third gear is axially slid to become engaged with the second gear or become disengaged therefrom, thereby establishing and interrupting the transmission of rotation of the input shaft to the output shaft.
