ていない。本発明はこの要望に応えて、その機能を充足
した画期的な新製品を提供せんとするものである。Conventionally, continuously variable transmissions include fluid, electric, and mechanical types, but none of them are perfect, and there is always some deviation in rotation ratio, and the power transmission efficiency is insufficient, resulting in problems with gears. I can't fight against the mesh. Furthermore, no matter how you look at gears, minute speed adjustments are impossible during transmission, and this is where the value of continuously variable transmissions lies, and the development of gear-type continuously variable transmissions has been desired for a long time. However, it has not been realized to date. In response to this demand, the present invention aims to provide an epoch-making new product that satisfies this need.

め車の摩耗と騒音を防止している。Next, the input shaft (
1) is pivotally supported by the input shaft frame (16), and the terminal is supported by the T-shaped shaft (
2), large bevel gears (3) each having 72 teeth are rotatably attached to both ends of the shaft, and the output shaft frame (17
) and is in mesh with a small bevel gear (5) having 24 teeth, which is directly connected to an output shaft (4) that is supported by an output shaft (4) at a tooth ratio of 3:1. Each large bevel gear is concentrically connected with a ratchet wheel (6) having 72 teeth facing south and rotating in the opposite direction to the rotation of the output shaft with a key (19). The ring (11) is held by a ring support frame (18),
Using the support pin (13) as a fulcrum, the axial angle of the ring can be moved by the handle (14) according to the handle guide (15). Now, when the input shaft is rotated by the handle without changing the shaft angle, the input shaft rotates while swinging around the large bevel gear on the figure 7 shaft, and at the same time the guide roller on the pedestal (10) rotates. (12
) rotates along the ring but does not oscillate, so the output shaft rotates once each time it rotates without imparting rotation to the large bevel gear. In this case, even if resistance from the output shaft side or rotation greater than the input shaft is applied, the two fixed to the connecting rod (8)
Due to the interaction of the two presser pawns (9) on the ratchet wheels, the former causes the simultaneous pawing of the presser pawns, and the latter prevents the free movement of the bevel gear on the figure 91 shaft by the simultaneous biting of the presser pawns, and the opposite This makes it impossible to transmit power from any direction, creating an irreversible power transmission mechanism. Next, when moving the axis angle of the ring along the handle guide with the handle, the guide roller rotates along the ring and swings left and right together with the arm shaft (7), and at the same time presses down the connected connecting rod. By repeating the biting and lifting of the ratchet wheel, the large bevel gear is rotated in the opposite direction to the rotation of the output shaft. It should be noted that biting in and lifting of the ratchet wheel and paw of the pusher is only possible by swinging the arm shaft, as shown in the shaded area in FIG. The repeated biting and lifting of the ratchet wheel prevents wear and noise on the ratchet wheel.

分を反対方向に押し廻して出力軸をＴ 逆回転させる。Now, when the axis angle of the ring is tilted by 15 degrees, the number of teeth of the large bevel gear in the oscillating section corresponds to 6 teeth in total from 0 degrees to 3 teeth on the left and right, and for 2 large bevel gears, each rotation A total of 12 teeth are rotated on the small bevel gear in the opposite direction to the rotation of the output shaft, thereby differentially rotating the small bevel gear and decelerating the rotation of the output shaft upward. Also, when the shaft angle is 30 degrees, 1
When the shaft angle is tilted to 45 degrees, the number of teeth becomes 36 teeth with two large bevel gears, which increases the number of teeth on the small bevel gear. Push the excess 12 sheets in the opposite direction and rotate the output shaft in the opposite direction.
また、６０度としたときは、歯数４８枚となシ、入力軸
を１回転する毎に出力軸を１逆回転させることが出来る
。Further, when the angle is 60 degrees, the number of teeth is 48, and the output shaft can be rotated once in the reverse direction for every revolution of the input shaft.
以上の如く、任意に軸角を移動して出力軸に零−を含む
正逆１００チの無段変速を与えることが出来る。As described above, the shaft angle can be moved arbitrarily to provide the output shaft with continuously variable speed of 100 degrees in forward and reverse directions, including zero.

車式無段変速機。The terminal of the rotatably supported input shaft (1) is connected to the T-shaped shaft (2).
), the large bevel gear (3) is rotatably mounted on both ends of the T-shaped shaft, and the small bevel gear is directly connected to the output shaft (4), which is rotatably supported with the same axis as the input shaft. (5), a ratchet wheel (6) that rotates in the opposite direction to the output shaft is connected concentrically to each large bevel gear, and the arm shaft (7) is rotatably connected to the midpoint of the T-shaped shaft. was attached, and a connecting rod (8) was rotatably passed through the neck of the arm shaft in parallel with the T-shaped shaft, and the connecting rod was arranged so that it could be alternately inserted into and raised by the ratchet wheel at both ends of the connecting rod. The presser clasps (9) are connected and fixed, and a roller pedestal (10) is rotatably attached to the end of the arm shaft, and a ring (11) is sandwiched on the roller pedestal to make the guy roller (12) rotatable.
), and the ring has a circular shape with the intersection of the T-shaped axes as the center and the length that touches the guide roller as the radius.Attach support pins (13) at two points on the outer periphery that divides the ring into two. A handle (14) in which a support pin is rotatably supported by placing the axis line equal to the input shaft, and the axial angle of the ring can be moved arbitrarily at the outer periphery of the midpoint of the ring between the support pins.
First, when the input shaft is rotated without changing the axis angle of the ring, the small bevel gear meshed with the large bevel gear rotates once together with the output shaft for each rotation. However, in response to the load on the output shaft side, the interaction of the two connected pressers prevents the large bevel gear on the T-shaped shaft from floating, and without transmitting power from the opposite direction. When moving the shaft angle of the ring, the guide roller rotates along the ring together with the arm shaft and swings on the section on the tooth profile of the large bevel gear created by the slope of the shaft angle. By repeating the loading process, the two large bevel gears are alternately given one rotation in the opposite direction to the rotation of the output shaft, and the meshed small bevel gears are differentially rotated to decelerate, stop, or reversely rotate the output shaft.
