できる遊星摩擦車機構を提供することが可能になる．DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a continuously variable transmission or a planetary friction wheel mechanism for a processing machine that uses a planetary friction wheel. (Prior Art) Conventional planetary gears or planetary friction wheels are known as transmissions capable of reverse rotation, but they have not been used as continuously variable transmissions. In addition, planetary gears or planetary friction wheels transmit driving force through gears, so there is no slippage in the direction of rotation, and the shift impact is large. It is common to use a clutch with conventional planetary gears or planetary friction wheels. Even in this case, one of the three coaxial basic axes is a fixed auxiliary axis. One is the input shaft and one is the output shaft, which is used as the decision mechanism. When changing gears, these roles are swapped, and this role swapping mechanism is also complex and large. ! A device for deforming a sun shaft material using a planetary roller that revolves on its own using a T-wheel is known, for example, from Patent Publication No. 46-43980, but there are three intermediate gears between the planetary gear and the sun gear. Because gears are involved, the structure of the revolving member becomes complex and large. Also, with this device, it is not possible to change the dimensions of the solar shaft material or to prevent twisting of the solar shaft material. Although it is possible to stop the rotation of the sun shaft with this device, it is not widely used because it requires two sets of drive devices with approximately the same capacity that can independently set the speed. A planetary friction wheel mechanism using friction wheels instead of gears can be considered, but in this case, the function is considered to be the same as a planetary gear mechanism except that slipping occurs between the friction wheels. Therefore, simply replacing the gear with a planetary friction wheel does not provide both a clutch function and a continuously variable transmission function, and the disadvantage is that the output rotational speed cannot be determined due to slippage between the planetary friction wheels. Only that remains. (Problems to be Solved by the Invention) In order to overcome the problems of the prior art as described above, the first object of the present invention is to provide a continuously variable transmission that has a clutch function and has a small shift impact. do. A second object of the present invention is to provide a continuously variable transmission that is small in size, has high rigidity, can significantly reduce speed, and can easily reverse rotation. A third object of the present invention is to provide a planetary friction wheel mechanism that is capable of changing the finished dimensions of the sun shaft member at the position of the sun shaft wheel. A fourth object of the present invention is to provide a planetary friction wheel mechanism that can prevent twisting of the sun shaft material and stop the rotation of the sun shaft material. Further, the present invention provides a planetary friction wheel mechanism in which when processing a sun shaft material without rotating it, one of the two human-powered shafts can be kept almost stationary or its rotation can be fixed and a drive source can be omitted. is the fifth objective. (Means for solving the problems) The present invention is configured as follows. As shown in FIGS. 1 to 7, the planetary friction wheel mechanism of the present invention has the following features: (1) The planetary friction wheel set 2 that clamps the sun shaft wheel or the sun shaft member 1 is supported and reinforced by the inner surface of the reinforcing ring 3. The planetary friction wheel set 2 is connected to a main drive shaft 4 for revolving the planetary friction wheel set 2 and a slave drive shaft 5 for rotating it on its own axis. A planetary gear or a planetary friction wheel 7 attached to the sun shaft 8 is connected to one sun gear or a sun friction wheel 8 on the side close to the sun shaft 8 to drive it, and the sun shaft wheel or the sun shaft member 1, the planetary A sun shaft 8 is used to operate one or more of the friction wheel set 2 and the reinforcing ring 3.
A slope is provided in the length direction of the sun axis 8, and one or more of them is positioned in the length direction of the solar axis 8. 12
This is a planetary friction wheel mechanism characterized by a structure that allows displacement and positioning. In the present invention, the sun shaft wheel or the sun shaft material 1 is compressed by the planetary friction wheel set 2, and the frictional force between the two is used to transmit power or process the shaft material. In such a mechanism, the state of power transmission differs depending on the pressing force between the two, resulting in an automatic transmission with a clutch function. In the present invention, in order to reduce the size and weight of the posture holding device of the planetary friction wheel set 2 and maintain its strength, the planetary friction wheel wL2 is supported and reinforced on the inner surface of the reinforcing ring 3, and the axle 6 of the planetary friction wheel set 2 is The installed planetary gear or planetary friction wheel 7 is meshed with one sun gear or sun friction wheel 9 on the side near the sun shaft 8 to minimize the number of gears or friction wheels. In addition, in the present invention, in order to provide a clutch function, a continuously variable speed function, and a function to change the dimensions of the shaft material,
Sun shaft wheel or sun shaft material 1. Planetary friction wheel set 2, reinforcement ring 3
A device 1, 10, 11, . 12 for displacement and positioning. When power transmission is important in the mechanism of the present invention, such as a clutch, the operating surface of one or more of the sun shaft wheel 1, the planetary friction wheel set 2, and the reinforcing ring 3 is attached in the length direction of the sun shaft. A gradient is applied, and one or more of them is displaced in the length direction of the solar axis using a positioning device. The Nanahachi sun shaft wheel 1 is controlled by the sun shaft wheel positioning device 10.
The planetary friction wheel set 2 is equipped with a sun shaft wheel positioning device 9, and the reinforcing ring 3 is a reinforcing ring positioning device! ! ! 12 to displace and position the sun shaft 8 in the length direction, and change and set the mutual pressing force between the friction wheels. In this way, if any one or more of the friction wheels is displaced in the length direction of the sun axis, their pressing force changes and the slip rate changes, allowing it to function as a clutch. The operation for performing continuously variable transmission in the mechanism of the present invention is the same as that for the clutch described above, but when used only as a transmission, each planetary friction wheel is moved in the axial direction without separating the planetary friction wheels from each other. Continuously variable speed is achieved by changing the relative position of the friction wheel and changing the operating radius. At this time, it is best not to change the pressing force between the planetary friction wheels and keep it within a predetermined range so that slippage does not increase. If the mutual pressing force between the planetary friction wheels is below a predetermined value, the slippage will increase and the mechanism will function as a clutch, so the mechanism of the present invention can also be used as a continuously variable transmission with a clutch function. Since the planetary friction wheel mechanism of the present invention is equipped with the reinforcing ring 3, it has high rigidity and is compact. Also, when the sun shaft is used as the output shaft, a significantly large deceleration is possible depending on the operating radius ratio, and the rotation of the sun shaft can be sequentially selected from forward rotation, zero rotation, and reverse rotation. Torque can be amplified. If the sun shaft material 1 to be processed is used instead of the sun shaft wheel, the finished dimension of the sun shaft material 1 can be changed in the length direction using exactly the same principles and operations as described above. In this case, the sun shaft material feed sun shaft wheel positioning device II! io, but if the planetary friction wheel set (planetary roller set) 20 axle 6 is twisted, the planetary roller set 2 is used. When the planetary friction wheel set 2 or the reinforcing ring 3 rotates, it is preferable that the contact point with the friction wheel of the positioning device be pressed by a wheel to create rolling friction. In this case, as shown in Figures 1 and 4, it is best to press in the direction in which the key is pressed, that is, in the direction in which pressing will do the work. In this case, if the pushing force is weakened, the positioning device will be pushed back by the mutual repulsive force between the friction wheels, making the return mechanism of the positioning device easier. In the present invention, the planetary friction wheel attitude holding device 1113 can be configured to be non-rotating or rotationally driven. For example, in Figures 1 to 6, there is a planetary friction wheel attitude holding device! 3 is rotationally driven by the main drive shaft 4, but in the examples shown in FIGS. 4 to 6, the main drive shaft 4 is not necessary if the reinforcing ring drive shaft 14 is driven. In other words, in the examples shown in Figs. 4 to 6, when the sun shaft or the sun shaft member 1 is used as the output shaft, the main drive shaft 4 or the reinforcing ring drive shaft 14 out of the three drive shafts 4, 5, 14. One of these is required, but the others can be omitted. Also, in the examples shown in Figures 4 to 6, the main drive unit l! Planetary friction wheel attitude holding system without using 5 [i! 213 can be used with the rotation fixed, but in this case the sun shaft wheel or sun shaft member 1 rotates. 2) The present invention is such that the planetary friction wheel set 2, which presses the sun shaft wheel or the sun shaft member 1 with the axle twisted in the same direction around the sun shaft 8, is supported and reinforced by the inner surface of the reinforcing ring 3.

This is a planetary friction wheel mechanism characterized by a structure that allows displacement and positioning. The technology described in section 1 is the same in this section. As in the present invention, the planetary friction wheel set 2 is pressed between the sun shaft wheel or the sun shaft member 1 with the axle 6 twisted in the same direction around the sun shaft 8, and the planetary friction wheel set 2 is pressed against the inner surface of the reinforcing ring 3. If the axle 2 is twisted in the same direction, in the case of an automatic transmission with a clutch function, the rotational direction of the planetary friction wheel set 2 increases the pressing force between the two. It is possible to select the direction in which to reduce the force, reduce the pushing force of the positioning device, and change the transmission force depending on the rotation direction, making it possible to use a one-way clutch. Also, when processing the sun shaft material, the axle 2 must be twisted in the same direction. By rotating the planetary friction wheel set, the sun shaft material 1 can be processed and simultaneously advanced in the length direction of the sun shaft. For example, in the configurations shown in Figures 1 and 4. To move the sun shaft from left to right when the sun shaft l does not rotate, hold the planetary friction wheel attitude 13
is rotated counterclockwise by the main drive shaft 4 when viewed from the left side of the figure. To advance the sun shaft member 1 from left to right in the figure by driving only the slave drive shaft 5, rotate the sun gear or sun friction wheel 10 to the left when viewed from the left in the figure. To move the solar shaft member 1 from left to right in the figure by driving only the reinforcing ring 3 in Fig. 4, rotate the reinforcing ring 3 to the left when viewed from the left in the figure. When processing the sun shaft material, the sun shaft wheel positioning device 10
can be used as a processing machine, for example, for rolling or grooving. 3) The present invention includes a substantially truncated conical planetary friction wheel set 2 that clamps the sun shaft wheel or sun shaft member 1 with the axle 6 twisted in the same direction around the sun shaft 8, and a reinforcing ring 3.
The planetary friction wheel set 2 is connected to a main drive shaft 4 that revolves around it and a slave drive shaft 5 that rotates it on its own axis, so that the planetary friction wheel set 2 rotates on its own axis. The planetary gear or planetary friction wheel 7 mounted on the axle 6 of the planetary friction wheel set 2 is configured to be driven by being coupled with one sun gear or sun friction wheel 9 on the side closer to the sun shaft 8, and this planetary gear Alternatively, the connection point between the planetary T9L friction wheel 7 and the sun gear or the sun friction wheel 9 should be configured so that it is approximately on a virtual conical surface C that is an extension of the planetary friction wheel working surface, and the sun shaft wheel or the sun shaft member l , a gradient number 9 in the length direction of the sun shaft 8 on the operating surface of one or more of the planetary friction wheel set 2 and the reinforcing ring 3. , 11. This is a planetary friction wheel mechanism characterized by being configured to be displaced and positioned by 12. The techniques described in sections 1) and 2) are the same in this section. In the present invention, the approximately circular trapezoidal planetary friction wheel set 2 is used by increasing the contact area with the inner surface of the reinforcing ring 3 to achieve Js! This is to reduce problems and to make it easier and more accurate to estimate the change in the interval between friction wheels or the change in the clamping force when positioning the friction wheels by displacing them in the sun axis direction. As long as the technical idea is adhered to, the present invention includes deformation from a substantially truncated conical shape. In other words, the term "approximately truncated cone" as used in the present invention includes a truncated cone, a shape similar to a truncated cone to which the idea of the present invention can be applied, and a shape synthesized based on a truncated cone. Also, a planetary friction wheel set 2 for rotating the planetary friction wheel set 2.
The point of connecting the planetary gear or planetary friction wheel 7 attached to the axle 6 with one sun gear or sun friction wheel 9 on the side closer to the sun shaft 8 is to prevent the sun shaft wheel or the sun shaft member from rotating much. The ratio between the rotation speed of the main drive shaft 4 and the rotation speed of the slave drive shaft 5 may be selected appropriately, but the slave drive shaft 5 can be almost stationary, and in some cases, it can be fixed or omitted without being driven. , as shown in Fig. 7, it is configured to lie approximately on a virtual conical surface C that is an extension of the operating surface of the planetary friction wheel. In the planetary friction wheel mechanism of the present invention, since there is slippage at the contact points of the friction wheels, the conditions for stopping the rotation of the sun shaft wheel or the sun shaft member vary from the above-mentioned virtual conical surface C depending on the conditions, but the amount of variation is plus or minus 20 to the cone angle
Variations within this range are included in the present invention. For example, in the examples shown in FIGS. 1 and 4, the planetary gear or planetary friction wheel 7 attached to the axle 6 of the planetary friction wheel set 20 is connected to the sun shaft 8J.
The point connecting with one sun gear or thick FQ friction wheel 9 on this near side is drawn closer to the center of the cone than the virtual conical surface C, but the amount of variation is less than 20% with respect to the cone angle, Included within the scope of the present invention. 4) The present invention includes a substantially truncated conical planetary friction wheel set 2 that clamps the sun shaft wheel or the sun shaft member 1 with the axle 6 twisted in the same direction around the sun shaft 8, and a reinforcing ring 3.
The planetary friction wheel set 2 is connected to a main drive shaft 4 that revolves around it and a slave drive shaft 5 that rotates it on its own axis, so that the planetary friction wheel set 2 rotates on its own axis. The planetary gear or planetary friction wheel 7 mounted on the axle 6 of the planetary friction wheel set 2 is configured to be driven by being coupled with one sun gear or sun friction wheel 9 on the side closer to the sun shaft 8, and this planetary gear Alternatively, the connection point between the planetary friction wheel 7 and the sun gear or the sun friction wheel 9 should be configured so that it is approximately on a virtual conical surface C that is an extension of the planetary friction wheel operating surface, and the apex P of this virtual cone is the sun axis 8. be configured so that it exceeds the opposite side.
and sun shaft wheel or sun shaft material 1. The working surface of one or more of the planetary friction wheel set 2 and the reinforcing ring 3 is sloped in the length direction of the sun shaft 8, and one or more of them is positioned in the length direction of the sun shaft 8 by a device 1i! ! 10, 11. This is a planetary friction wheel mechanism characterized by being configured to be displaced and positioned by 12. The techniques described in sections l) to 3) are the same in this section.
In the present invention, as shown in FIGS. 1, 4, and 7, the apex P of the virtual cone is configured to exceed the solar axis 8 in the opposite direction, thereby making it possible to process the solar axis material. No twisting occurs in the shaft material. In the planetary friction wheel mechanism of the present invention,
Sun shaft wheel or sun shaft material 1, planetary friction wheel set 2, reinforcing ring 3
A slope is applied to one or more of the operating surfaces in the length direction of the sun axis 8, and one or more of the types is positioned in the length direction of the sun axis 8! 10. By configuring the solar shaft to be displaced according to 11.12, it is possible to change the position of the apex P of this virtual cone and select conditions under which the twist of the solar shaft material disappears. 5) The present invention is characterized in that the reinforcing ring 3 is driven and the planetary friction wheel set 2 is driven to revolve by the frictional force between the reinforcing ring 3 and the planetary friction wheel set 2. This is the planetary friction wheel vAm described above. If the reinforcing ring 3 is driven by the reinforcing ring drive shaft 14 as shown in FIGS. 4 to 6, the planetary friction wheel set 2
It revolves and rotates in the same direction as the reinforcing ring 3 due to the frictional force between it and the reinforcing ring 3. With this configuration, the main drive shaft 4 and its transmission mechanism, which are more complicated and less rigid, are unnecessary, and the entire device can be made smaller and more rigid. The planetary friction wheel machine of the present invention described above can also be applied to drilling pipe materials or shaft materials. If the outer diameter of the sun shaft material is reduced by machining, it is the same as the case of the sun shaft material processing described above, but if the outer diameter is expanded by machining, the solar shaft material shown in Figure 1 or 4 is You can think of it as moving from right to left in the figure during machining. In this case, if the sun shaft does not rotate (~), the planetary friction wheel set will revolve to the right when viewed from the left in the figure. (Effects of the Invention) With the above configuration, the present invention enables a continuously variable transmission with a clutch mechanism that does not require a separate clutch and has a small shift impact. Furthermore, the present invention makes it possible to provide a continuously variable transmission that is compact, has a wide range of rigidity, can significantly reduce speed, and can easily reverse rotation. Furthermore, it becomes possible to create a planetary friction wheel mechanism in which the finished dimensions of the shaft material at the position of the sun shaft wheel can be changed. It also becomes possible to provide a planetary friction wheel mechanism that can eliminate twisting of the sun shaft and stop the rotation of the sun shaft. Further, according to the present invention, there is provided a planetary friction wheel mechanism in which one of the two input shafts can be kept almost stationary or its rotation can be fixed and a drive source can be omitted when processing the sun shaft material without rotating it. becomes possible.
