Abstract

PURPOSE:To permit the free speed change in a wide range by allowing the input of an input shaft to transmit revolution onto an internal gear from an external gear, while transmitting the revolution to bevel gears from other bevel gears, thus removing the constant torque part. CONSTITUTION:Bevel gears 10 and 17 and an external gear 2 are installed integrally onto an input shaft 1. An internal gear 3 in eccentricity for the external gear 2 is revolved by an eccentric shaft 4 together with a sun gear 5, and a planetary gear 6 is supported by a revolution shaft 9 and meshed with an output internal gear 7. While, the secondary input bevel gear 17 revolves the bevel gears 16 and 19 installed onto a revolution shaft 15, and further a bevel gear 10 revolves a countershaft gear 11 and a frictional wheel 12 which moves in sliding on the input shaft 1. A frictional plate 13 can be press-attached with the frictional wheel 12, and speed change is carried out by the rotation and revolution of the planetary gears 16 and 18 on a Z-axis.

Description

[Detailed description of the invention] (Industrial application field) This invention relates to a continuously variable transmission.

(Prior art) The prime movers of machine tools, automobiles, etc. are constructed to maintain high efficiency at almost constant rotation, but on the other hand, these prime movers are not necessarily used at constant rotation. Instead, a transmission is used to freely vary a constant rotation within an arbitrary range using a selective gear mechanism, a fluid torque converter, or an expensive electric converter. However, even if the above-mentioned transmission device was used in the past, it was not always satisfactory.

In order to eliminate the above-mentioned shortcomings first), I applied for
It was registered after reaching the summit of Mt. 81579.

This application attempts to improve the deficiencies of the invention of the above-mentioned Japanese Patent Application No. 53-081579 (for example, slipping occurs due to reaction force of the output shaft) by using a drying method.

(Means for solving problems) The drawing is a front view of one embodiment of the invention.

(1) is the input axis and is the original! tlli (not shown)
The bail gear CLq and the bail gear (
(b) and external gear (2) are integrally provided and rotate while positioned at tζ on the input shaft.

Next, the internal gear (3), which is aligned on the Y axis with respect to the external gear (2), passes through the eccentric shaft (4) to the sun gear (input gear).
(5) are integrally bound together to form an a-sea that rotates freely within one center on the Y-axis within (φ) and the revolution axis (9).

For the thick gear (5), the planetary gear (6) is supported by the gear shaft (9) so that it can be freely connected.Next, the planetary gear In (6), the output internal gear (7), which becomes one with the output shaft (8), meshes and receives the input from (6) and rotates freely ζ, resulting in the output shaft (8).
It is designed to output to .

On the other hand, the secondary gear (1) is integrated with the input shaft (1) and rotates the gear (16) that is eccentric on the Z axis supported by the revolution shaft (2) for speed change. The bail gear (181) that can be made into one body with the internal gear (8) is designed to rotate the bail gear θ casting that can become one body with the internal gear (8). The gear name is the counter shaft gear (
The above-mentioned friction wheel (1) is rotated to rotate the friction wheel (2) which is attached to be able to move on this glaze.
The friction plate (12) can be pressed against 20&''C (the friction plate (ts) is pressed against 4) and can be rotated as desired by moving it in the direction of the arrow.

The friction plate has one hollow shaft (b), and the inside is an input shaft (
In contrast to 1), the outside is designed to rotate freely relative to the shaft, which is a part of the output shaft (8).

Next, the hollow shaft 0→ has a speed change revolution shaft (B), and the speed is changed by rotating and revolving the planetary gears (181) and (181) on the Z axis.

(21) is the balancing weight.

With the above configuration, the input from the input shaft (1) is sent to the internal gear (8) via the external gear (21'+ζ) on the one hand, and to the Beer gear (B), to the Elibere gear (to), and to the Beer gear ( ) through the internal gear (3) and one bell gear (1).
By giving rotation to 91 and entering the input in two directions, the internal gear (3), anti-intermediate shaft (4) and sun gear (input gear)
For (5), rotation and revolution are given to the revolution axis (9) and revolution (since it is eccentric on the Y axis) to the octopus.

With the above configuration, the external gear (2) and internal gear (
8) No! ! 3rd point, bell gear <17), shifting bell gear (16), and shifting bell gear <181
The pressure contact part of the internal gear (31) and the free point of one bail gear (1 false) prevents slipping (friction wheel (2) and friction plate α3). ).

Also, these gears are constructed with gear ratios that prevent them from locking.

With the above configuration, the external gear (2) and internal gear (
The meshing point of 8) and the bell gear (B) and the bail gear) and the bail gear (C) and the meshing point of The Y-axis (revolution axis) is rotated by that amount while maintaining the sameness (half a rotation), and the two axes are not rotated by the reaction force. It is easy to turn the friction wheel, and the friction wheel @ (b) (13) is smooth. This friction wheel is just an example, and other methods may be used (function) Next, this transmission To explain the operations of Since the angular velocity of the entire part is the same and the structure is as described above, the entire part becomes locked and the meshing motion of the gears stops.As a result, the revolution axes (9) and (9)
) are also locked, so gear (5) and planetary gear (6)
) and the lock and output internal gear (A) are also locked, so the entire gear in this part also stops its meshing motion and is in a state where the entire gear is in a state of revolution and rotating at the same time as the input shaft (1).

Next, looking at this lock, if you move the friction wheel upwards in the direction of the arrow, the friction plate will rotate more slowly than the input shaft (1), so it will rotate at 4 #i (speed change). (B) is retracted and therefore has the above-mentioned configuration, so the meshing point of external gear (2) and internal gear (3) and bail gear α are connected to (16) and (
! The meshing point of the fourth gear (1) moves back, and the revolution axes (9) and (9) move back due to the action of the Y-axis. Therefore, since the configuration is as shown in the figure, the planetary gear (6) idles by that amount. Therefore, the rotation of the output shaft (8) is decelerated.As the rotation of the friction force is further slowed down, the output shaft (8) decelerates even more and when the rotation reaches a certain level, the output shaft (8) finally stops. If the rotation of the friction plate (13) is slowed down, reverse rotation can be obtained to a certain extent.In addition, if the rotation of the friction plate θ is made faster than the rotation of input #1 (1), the rotation of the friction plate θ is increased by that amount. output i
! It goes without saying that the rotation of the 1lh (8) can be made faster than the input shaft (1) to some extent.

(Effects of the Invention) With the above-mentioned configuration, the transmission according to the present invention can eliminate the constant-torque portion that is found in general continuously variable transmissions. It has a high power output and can freely shift gears from heavy loads (low rotation E> to high rotation), and because it uses rime, it rotates reliably and is a high-efficiency vehicle, so its range of applications is extremely wide (for example, These include transportation equipment, machine tools, construction equipment, agricultural machinery, and other general industrial machinery.

Incidentally, this strange thing: Since device a uses many gears, it tends to be thought that it is very inefficient, but since the input is divided into two, each load is half, and the loss is also 2 minutes. It won't be that bad since you can do it.
