First, the conventional technology will be explained with reference to FIGS. 1 and 2. FIG. 1 shows a device layout of a drive mechanism of a railway vehicle, and FIG. 2 shows a sectional view of a gear joint in FIG. 1. In FIG. 1, power is transmitted from a motor 5 to a drive device 3 via a gear joint 4.
The drive device 3 and the wheels 2 are fixed to the axle 1, and the wheels 2 and the axle 1 are rotated by rotation of the gears in the drive device 3. Furthermore, as shown in FIG. 2, the gear joint 4 is constructed by meshing an inner cylindrical joint 7 with an outer spline and an outer cylindrical joint 6 with an inner spline.
The escape direction regarding attachment, that is, the up, down, left, right, front and rear directions, can be absorbed by the gear joint portion 8. Power is transmitted as shown by the dashed line in the figure.

量が増えて台車のばね下荷重が増えるというよう
な欠点があつた。 However, in the conventional drive system using gear joints, the gear joint itself does not have a deceleration function.
When replacing the motor due to a change in motor specifications (rotational speed, etc.) or setting a new vehicle speed, the reduction ratio cannot be achieved by one-step reduction of the drive device 3 itself, and when changing the reduction ratio within the drive device 3, It takes time and effort to design the drive device, and even if a two-stage reduction ratio is used, the drive device itself becomes large, which increases the weight and unsprung load of the truck.
本発明の目的とするところは、駆動軸と被駆動
軸との軸心の相対的な変位を許容し、かつ、変速
機能を有した歯車継手を提供することにある。
An object of the present invention is to provide a gear joint that allows relative displacement of the axes of a drive shaft and a driven shaft and has a speed change function.

The present invention provides a cylindrical joint that is fixed to a drive shaft and a driven shaft that are disposed with their axes shifted from each other and that has circular arc teeth, an internal gear that meshes with one of the internal cylindrical joints, and an internal cylindrical joint that meshes with the other internal cylindrical joint. an outer cylindrical joint with an external pinion provided concentrically with the internal gear on the side; an internal gear that meshes with the other internal cylindrical joint; and an external pinion that meshes with the external pinion. an outer cylinder joint having a large diameter and an internal gear provided on the one inner cylinder joint side; and an external pinion gear of the one external cylinder joint and an internal gear of the other external cylinder joint are meshed. and an outer cover that is rotatably supported by a bearing in a state in which the outer cover is rotated.

側の軸心は一致しない。 In FIGS. 3 and 4, the inner cylinder joint 7 and the gear joint part 8 have the same structure as the conventional one, and the outer cylinder joint part is divided into an external cylinder joint 9 with an internal gear and an external cylinder joint 13 with a small gear. They are connected by a meshing part 14, and the outer periphery of the external cylindrical joint 9 with an internal gear connects the input and output parts with outer covers 11 and 12 via a bearing 10, respectively. Power is transmitted as shown by the dashed-dotted line in the figure, and deceleration is performed. At this time, the outer lids 11 and 12 are supported by the outer lid support arm 18 on the truck frame or the like. In this embodiment, the axes of the input side and the output side do not coincide.

が行なわれる。 Other embodiments shown in FIGS. 5 and 6 are those in which a small gear 15, a support arm 16, and a pin 17 are added to the above embodiment so that the axes of the input side and the output side are aligned. Power is transmitted as shown by the dashed-dotted line in the figure, and deceleration is performed.

継手と同一の構造としているため問題はない。 By doing the above, for example, when replacing a motor with a new specification or setting a new vehicle speed in a vehicle's drive system, there is no need to change the reduction ratio of the drive system installed in the axle, and the gear By changing only the joint, the increase in overall weight can be suppressed, and the reduction ratio can be increased, making it easy to handle. Furthermore, there is no problem with respect to the clearance direction for installation, that is, the front, back, left, right, top and bottom directions because the structure is the same as that of a conventional gear joint.
