Description

[Detailed description of the invention] The present invention relates to a device that can automatically connect the rotating shaft of a driven part to the rotating shaft of a driving part during high-speed rotation, and is particularly useful for performance testing of transmissions. It is suitable for this purpose.

When testing transmission durability, etc., a load such as a flywheel is applied to the transmission output shaft to rotate it at high speed, and the flywheel input shaft is connected to the transmission output shaft. It is necessary to connect the two. As shown in FIG. 1, which schematically shows the connection structure between the output shaft of the transmission and the input shaft of the flywheel in a conventional transmission test device, the transmission 12 rotated at high speed by the drive motor 11 is mounted on a mount. It is detachably attached to a bracket 14 installed on the transmission 13, and is connected to the output shaft 15 of the transmission 12 and the flywheel 16 facing the output shaft 15.
ball joint 18 connected to the input shaft 17 of
It is designed so that it can be spline fitted. A flywheel 16 connected to a tuning motor 20 via a clutch 19 is connected to an output shaft 15 of the transmission 12 by actuation of a hydraulic cylinder 21.
The frame 22 is placed in a direction parallel to the axis of the
It is rotatably supported on a slide table 23 that slides on it. Therefore, the tuning motor 2
Even if an attempt is made to connect the output shaft 15 of the transmission 12 and the ball joint 18 while driving the transmission 0, since the ball joint 18 is not supported, the operation of the fluid pressure cylinder 21 automatically connects the output shaft 15 of the transmission 12 to the ball joint 18. Since the output shaft 15 of the transmission 12 and the ball joint 18 cannot be connected, the drive motor 11 and the tuning motor 20 must be stopped or decelerated to connect them manually. was.

Therefore, when performing performance tests on a large number of transmissions, the output shaft 15 of the transmission 12 must be rotated at high speed.
Since it is impossible to connect the ball joint 18 to the drive motor 11, the drive motor 11 must be stopped or decelerated frequently, and the time required for this is completely wasted, resulting in extremely low work efficiency. There was a flaw that made it worse.

The purpose of the present invention is to provide a device that eliminates such drawbacks when connecting the output shaft of the conventional transmission and the input shaft of the flywheel and enables automatic connection under high-speed rotation. do.

The configuration of the automatic coupling device for high-speed rotating shafts of the present invention that achieves this purpose includes a pedestal on which a high-speed rotating drive section is installed, and a pedestal that is mounted on the pedestal in a direction parallel to the axis of the rotating shaft of the drive section. One end is connected via a diaphragm coupling to a rotating shaft of a sliding table that moves back and forth and a driven part installed on the sliding table, and the other end is connected to the rotating shaft of the driving part as the sliding table moves forward. The device includes a connecting shaft that can be spline-fitted, and an alignment member provided on the slide table, and the alignment member includes a V block that rotatably supports the connecting shaft, and a V block that rotatably supports the connecting shaft, and the connecting shaft is connected to the The present invention is characterized by comprising an actuator that supports the V-block so as to be movable up and down so as to be coaxial with the rotation axis of the drive section.

Hereinafter, an embodiment in which the automatic coupling device for high-speed rotating shafts according to the present invention is applied to a transmission performance test device will be described in detail with reference to FIGS. 2 to 4. It goes without saying that the present invention can be applied to any device in which it is necessary to connect the rotating shaft of the driving part and the rotating shaft of the driven part. Note that the same reference numerals are used for members having the same functions as those of the conventional device shown in FIG. 1, and the description thereof will be omitted. As shown in FIG. 2, which shows the schematic configuration of this embodiment, a flywheel 1
A connecting shaft 24 that can be spline-fitted with the output shaft 15 of the transmission 12 is connected to the input shaft 17 of the transmission 12 via a diaphragm coupling 25. As shown in Figure 3, the flexible unit 28 is attached between the flanges 26 and 27 via bolts 29 and nuts 30 to correct misalignment between the connection shaft 24 and the input shaft 17 of the flywheel 16. At the same time, flange 2
This is a flexible shaft joint that functions so that the distance between the output shaft 15 of the transmission 12 and the connection shaft 24 is smoothly spline-fitted by changing the distance between the shafts 6 and 27. On the slide table 23, there is a connecting shaft 2.
An alignment member 31 is installed that can rotatably support the transmission 4 and position it coaxially with the output shaft 15 of the transmission 12, and the left side shape of the alignment member 31 in FIG. As shown in FIG. 4, the alignment member 31 includes a bracket 32 fixed to the slide table 23, and a piston rod 33 attached to the bracket 32.
A hydraulic cylinder (actuator) 34 that can vertically move up and down, and a piston rod 33 of the hydraulic cylinder 34 that is attached to the upper end of the piston rod 33 and connected to the connecting shaft 2.
4 and a V block 35 located directly below the V block 35. A stopper 3 is provided at the lower end of the piston rod 33 to determine the lowering end of the piston rod 33 by coming into contact with the surface of the slide table 23.
6 is provided.

When connecting the connecting shaft 24 to the output shaft 15 of the transmission 12 which is being rotated at high speed by the drive motor 11, the fluid pressure cylinder 34 is first activated to raise the V block 35 to the rising end, and the transmission 12 The connecting shaft 24 is automatically positioned coaxially with respect to the output shaft 15 of to move the slide table 23 toward the transmission 12. As a result, the connecting shaft 24 abuts against the output shaft 15 of the transmission 12, and the diaphragm coupling 2
Although the connecting shaft 24 is pushed back due to the elastic deflection of the slide table 23 despite the forward movement of the slide table 23,
When the spline position of the output shaft 15 and the spline position of the connecting shaft 24 coincide, the connecting shaft 24 moves forward due to the elasticity of the diaphragm coupling 25, and these mesh with each other to form a spline fit. By fitting the output shaft 15 and the connection shaft 24, the output shaft 15
Since the inertial resistance of the flywheel 16 will be applied to this, the clutch 19 is disengaged at this time so that the flywheel 16 is rotated only by the driving force of the drive motor 11. Note that the connection between the output shaft 15 and the connection shaft 24 can be released using the slide table 23.
Only the backward movement is required.

As described above, according to the automatic coupling device for high-speed rotating shafts of the present invention, the connecting shaft is automatically coaxially positioned with respect to the rotating shaft of the driving part by the V block and the actuator, and the connecting shaft and the rotating shaft of the driven part are automatically positioned coaxially. Since they are connected via a diaphragm coupling, which is one of the flexible shaft couplings, it is possible to automatically connect the rotating shaft of the driven part to the rotating shaft of the driving part, which is rotating at high speed. Therefore, when the present invention is applied to a transmission performance test device,
The work efficiency can be significantly higher than before.
