Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a honing machine for finishing a tooth surface after quenching a gear to be processed, for example, when manufacturing a gear used for an engine or a transmission of an automobile. The aim is to reduce noise at times of emergency.

[0002]

2. Description of the Related Art Honing of a gear is a processing method in which a quenched and hardened gear is ground to efficiently improve the roughness of the tooth surface. In general, by using a gear-shaped grinding wheel (gear horn), the quenched and hardened work gear is meshed and rotated while giving an axis crossing angle, so that the tooth surface of the work gear is finely ground. It is intended to make it possible to manufacture a gear with reduced noise by improving the roughness of the tooth surface (for example, see JP-A-3-202225, especially FIG. 1).

That is, the mechanism of a honing machine is generally
This is the same as that shown in FIG. 1 in the present invention. The grindstone gear 1 and the work gear 2 are engaged with each other so that their respective axes have an intersection angle, and are controlled by respective motors 3 and 4 controlled to rotate in inverse proportion to the ratio of the number of teeth. It is made to rotate. When the grindstone gear 1 and the work gear 2 rotate in this state, a relative sliding speed is generated on the tooth surface 14 of the work gear 2 so that the material on the tooth surface 14 is ground and removed. The reference numerals are common to those of the present application.

The conventional control means 7 in the above honing machine is as shown in FIG. The rotation pulse instructing means 23 instructs each of the motors 3 and 4 to output a synchronous rotation pulse so that the grindstone gear 1 and the work gear 2 rotate in inverse proportion to the ratio of the number of teeth. The difference between the rotation angles detected by the sensors 5 and 6 provided on the shafts of the motors 3 and 4 and the rotation angle expected by the command means 23 is detected, and the correction pulse command means 22 issues a correction pulse command. To rotate at the correct rotation position.

[0005]

However, the conventional honing machine described above has a problem that the effect of improving and correcting the accumulated pitch error is not so large even if honing is performed on the gear to be processed. Was.

That is, the gear 3 to be processed is generally, for example, shown in FIG.
As shown in FIG. 22, for example, the pitch error of the pitch error waveform 24 shown in FIG. Have. Therefore, the processed gear 2 has
An accumulated pitch error has occurred, and when the wheel is engaged with the grinding wheel 1 and rotated, for example, as shown in FIG.
A rotation deviation of the rotation deviation waveform 16 having a pitch of one rotation is generated.

Therefore, in order to make the tooth surface of the gear after honing to have a small amount of eccentricity h with respect to the rotation center Q, as shown in FIG. 3, a direction perpendicular to the eccentric direction (the right and left direction in FIG. In the tooth surfaces 14 of the teeth b) and d), the allowance 15 is made to have a large or small difference in advance. If the motors 4 and 5 of the honing machine rotate completely synchronously and the rigidity between the grinding wheel 1 or the gear 2 and the motors 4 and 5 is high, the rotational deviation decreases as the honing process proceeds. , The accumulated pitch error should also be reduced.

However, in the honing machine, generally, the connecting shafts and intermediate gear devices 19 and 20 interposed between the grinding wheel 1 and the gear 2 and the motors 3 and 4 have an elastic effect in the rotating direction. The grinding wheel 1 and the motor 3 have the same elastic effect. Due to this elastic effect, when the gear 2 having a pitch error is honed, the size of the allowance 15 is set on the tooth surface 14 at the left and right positions b and d in FIG. It is difficult to process while maintaining it.

That is, as shown in FIG. 4, since the tooth surface pressure p due to the pressing force P in the cutting direction is small, the above-mentioned left and right positions b, b in FIG.
There is no difference in the size of the allowance 15 at d.
Therefore, when the work gear 2 is rotated while meshing with the grindstone gear 1, a rotation deviation having a pitch of one rotation of the gear also occurs as shown in FIG. As a result, for example, as shown in FIG. 24, the gear 2 to be processed after the honing processing has a problem that the accumulated pitch error is not much improved or corrected as compared with the gear before processing.

SUMMARY OF THE INVENTION An object of the present invention is to solve the problems of the conventional gear honing machine. That is, an object of the present invention is to provide a gear that can efficiently manufacture a high-precision gear by making it possible to optimally control the rotation angle or the rotation speed of at least one of the work gear and the grinding wheel gear with a relatively simple configuration.

It has a function to adjust.

The grinding gear 1 or the work gear 2

Or, information obtained by measuring the rotation angle (or rotation speed) of both the grinding wheel 1 and the work gear 2 is sent to the motor 4 of the work gear 2 to adjust the rotation, or There is a method in which information obtained by measuring the rotation angle (or rotation speed) is sent to the motor 3 of the grinding wheel 1 to adjust the rotation.

The rotation deviation calculating means 8 calculates the theoretical rotation speed or the theoretical rotation speed of the work gear 2 calculated in inverse proportion to the gear ratio from the rotation angle (or rotation speed) of the grinding wheel 1 or the work gear 2. Data obtained by detecting the deviation of the actual rotation angle (or rotation speed) of the processed gear 2 with respect to the rotation angle, that is, the rotation deviation, in relation to the rotational position of the processed gear 2 is subjected to Fourier analysis to obtain the data of the processed gear 2 It is preferable to have a function of analyzing the rotational order component.

The rotational deviation calculating means 8 calculates the rotational angle (or rotational speed) of the grinding wheel 1 or the gear 2 to be processed.
The deviation of the actual rotation angle (or rotation speed) of the processed gear 2 from the theoretical rotation angle (or rotation speed) of the processed gear 2 calculated in inverse proportion to the gear ratio is determined by the rotation of the processed gear 2. The data detected in relation to the position is processed gear 2
It is desirable to have a function of approximating a sine function having the rotation cycle of
See FIG. 11).

The adjustment value calculating means 9 calculates the information for adjusting the rotation angle (or rotation speed) of the grinding wheel 1 or the work gear 2 with respect to the theoretical rotation angle (or rotation speed). Corresponding to the analysis of the rotational order components of the gear 2 to be processed as described above, the amplitudes are proportional to the amplitudes of the components or determined by a constant arithmetic expression, and the phase difference determined in advance for each component is It is preferable to have a function of determining whether or not to have.

The adjustment value calculating means 9 calculates information for adjusting the rotation angle (or rotation speed) of the grinding wheel 1 or the work gear 2 with respect to the theoretical rotation angle (or rotation speed). As described above, in correspondence with the sine function having the rotation period of the work gear 2 as a cycle, the amplitude B of the sine function is proportional to the amplitude A of the sine function or is determined by a constant arithmetic expression. It is desirable to have a function of determining whether to have it (see FIG. 12, for example).

The adjustment signal instructing means 10 is for giving the information from the adjustment value computing means 9 to at least one of the motors 3 and 4 to adjust the rotation. It is also possible to have functions and integrate them. It is preferable that the above information is automatically given to the motors 3 and 4 as a signal. However, it is also possible to give the information by a dial system or a numerical input system on a control panel of the honing machine.

The operation states of the first, second and third embodiments of the present invention are as follows. Whetstone gear 1 and work gear 2
Is rotated by the motors 3 and 4, the rotation of the motors 3 and 4 is controlled, and the grindstone gear 1 and the work gear 2 rotate in inverse proportion to the gear ratio. That is, the difference between the rotation angle (or rotation speed) scheduled by the rotation pulse command means 23 and the rotation angle (or rotation speed) detected by each of the sensors 5 and 6 is detected, and at least one of the motors 3 and 4 detects the difference. A synchronous rotation pulse is commanded to rotate at the correct rotational position, and the rotation is corrected.

Also, in a configuration in which the motor 4 on the side of the rotating gear wheel 1 rotates with the rotation of the gear wheel 2 meshed with the rotating grinding wheel gear 1, only the grinding wheel gear side motor 3 uses the rotation pulse command means 23. The rotation is instructed by the correction pulse from
3 does not receive the synchronous rotation pulse, and is rotated by the grinding wheel 1.

In any of the above configurations, the grinding wheel gear 1
And the gear 2 to be processed are meshed with each other at a given crossing angle, so that the relative slip speed is generated by the crossing angle on each tooth surface of the rotating grinding wheel gear 1 and the gear 2 to be processed. Then, the material of the tooth surface 14 of the processed gear 2 is finely ground and removed by the grinding wheel 1, and the honing is performed.

The gear 2 to be machined generally has a pitch error having a pitch error waveform as described above because the gear center O has some eccentric error with respect to the rotation center Q as shown in FIG. (For example, FIG. 22 described above)
reference). When the work gear 2 is rotated while meshing with the grindstone gear 1, a rotation error occurs in a rotation error waveform having a pitch of one rotation of the work gear 2 (for example, see FIG. 23).

Therefore, the gear 2 to be processed after the honing processing is performed.
However, in order to eliminate the amount of eccentricity h between the center position O and the rotation center Q, the tooth surface 1 is set at the left and right positions b and d in FIG.
The difference between the size 15 and the allowance 15 of 4 is provided. However, in practice, the left and right positions b and d in FIG. 3 described above are caused by the elastic effect in the rotating direction by the connecting shaft of the honing machine, the intermediate gear device, or the grinding wheel 1 and the motor 3 itself.
The clearance 15 given to the tooth surface 14 has no large or small difference. Therefore, conventionally, even after the honing, the accumulated pitch error of the processed gear 2 is rarely corrected or corrected (for example, see FIG. 24).

However, in the gear honing machine according to the present invention, as described above, the sensors 5 and 6 for detecting the rotation angle (or rotation speed) of the grinding wheel 1 and the work gear 2 are used.
Also, as a part of the control means 7, there are provided a rotation deviation calculating means 8, an adjustment value calculating means 9, and an adjustment signal instructing means 10.

The rotation deviation calculating means 8 obtains a rotation deviation waveform 16 having a pitch of one rotation of the gear 2 to be processed (for example, see FIG. 10). The adjustment value calculating means 9 analyzes the rotational deviation waveform 16 to obtain a sine waveform 17 having a pitch of one rotation of the processed gear 2 (see, for example, FIG. 11). , And an adjustment signal waveform 18 having an amplitude B obtained as a function of and a phase difference で き る that can be arbitrarily specified (for example, see FIG. 12). The adjustment signal waveform 18
Can be obtained from the rotation deviation waveform 16 without passing through the sine waveform 17.

The adjustment signal instructing means 10 sends an adjustment signal based on the adjustment signal waveform 18 to at least one of the motors 3 and 4 (the motor 4 on the gear to be processed) on the grinding wheel 1 or the gear 2 to be processed. It is instructed.

In this manner, the rotation of the work gear 2 relative to the theoretical rotation angle (or rotation speed) of the work gear 2 calculated from the rotation angle of the grindstone gear 1 in inverse proportion to the gear ratio. The deviation of the angle (or rotation speed) is detected in relation to the rotation position of the work gear 2 and the rotation angle (or rotation speed) of the grinding wheel 1 or the work gear 2 is calculated based on the information. Point rotation angle (or rotation speed)
The information to be adjusted is calculated, the signal amount to be adjusted is calculated, and an adjustment signal is instructed to at least one of the motors 3 and 4 to adjust the rotation.

In the above-mentioned case, in a configuration in which the rotating gear wheel 1 is engaged with the rotating grinding wheel 1 so as to rotate, the gear 2 to be machined or the motor 4 of the motor 4 on that side rotates. A deviation of the rotation angle (or rotation speed) is detected in relation to the rotation position, and based on the information, information to be adjusted for the theoretical rotation angle (or rotation speed) of the processed gear 2 is calculated. Then, the signal amount to be adjusted is calculated, and an adjustment signal is instructed to the work gear side motor 4 to adjust the rotation.

Accordingly, in any of the above cases, the gear center O has an eccentric error with respect to the rotation center Q, and a cumulative pitch error occurs. When the gear O is engaged with the grinding wheel 1 and rotated, a rotational deviation occurs. Gear 2
The rotation of at least one of the motors 3 and 4 of the grinding wheel 1 and the processing gear 2 approximates the theoretical rotation angle (or rotation speed) depending on the mutual rotation position of the grinding wheel 1 and the processing gear 2. Adjusted to things.

Thus, as the honing is advanced by the gear honing machine according to the present invention, the rotational deviation and the accumulated pitch error of the gear 2 to be processed decrease (for example, see FIG. 13), and the tooth surface 14 is corrected. -It will be corrected, and high-precision gear processing will be performed.

In the adjustment value calculating means 9, the rotation angle (or rotation speed) of the grinding wheel 1 or the work gear 2 is determined.
Is calculated with respect to the theoretical rotation angle (or rotation speed), high-order components of the rotation of the processed gear 2 are analyzed, and a proportional or constant calculation is performed on the amplitude of each component. An adjustment signal having an amplitude determined by the equation and a phase difference predetermined for each component may be generated, and a signal may be commanded to one of the motors 3 and 4 to adjust the rotation.

2) Next, the control means 7 in the fourth embodiment of the present invention will be described focusing on the differences from the first, second and third means. It comprises a rotation deviation calculation means 8, a control command value output means 11, a position signal creation / transmission means 12, and a gain command means 13 (for example, see FIG. 15). This is because while rotating the grinding wheel gear side motor 3 at a constant speed, the motor 3 and the processing gear side motor 4
Are controlled in a predetermined relationship, that is, by a predetermined position setting model.

When the gear 2 to be processed rotates at a constant speed, that is, when the grinding wheel gear-side motor 3 rotates at a constant speed as described above, the rotation deviation calculating means 8 causes the gear 2 to rotate.
When the gear rotates in inverse proportion to the gear ratio,
The deviation of the rotation angle (or rotation speed) is detected in relation to the rotational position of the gear 2 to be processed, and the phase and amplitude of the deviation are calculated (for example, see FIGS. 16 and 17). .

The control command value output means 11 outputs a value for changing the start phase of the preset position setting model and a value for changing the feedback gain, respectively, based on the information in the rotational deviation calculating means 8. It is possible. This corresponds to the adjustment value calculating means 9 in the first, second and third embodiments of the present invention.

The above-mentioned position setting model, that is, the relationship defining the rotational angle positions of the grinding wheel gear side motor 3 and the work side gear side motor 4 is based on the relationship between the grinding wheel gear 1 rotating at a constant speed in inverse proportion to the number of meshing teeth. For a straight line l representing the relationship of the processing gear 2,
It is desirable that a gentle sine waveform be superimposed (for example, see FIG. 19).

The position signal generating / transmitting means 12 generates and transmits a position signal to each of the motors 3 and 4 using the start phase change value s, and the gain commanding means 13 outputs the feedback signal. Using the gain change value t, the grinding wheel gear side motor 3 or the work gear side motor 4
Then, a gain is commanded so as to cancel an error with the position setting model. The gain command is not always continuous, but may be issued intermittently or when necessary.

The operating state of the fourth embodiment of the present invention is as follows.
It is as follows. Here, too, the grinding wheel 1 and the work gear 2
Is a state in which the grindstone gear 1 and the work gear 2 are rotated at a substantially constant speed in inverse proportion to the gear ratio by the motors 3 and 4, and the grinding wheel gear 1 and the work gear 2 are given an axis crossing angle. Are engaged. Therefore, a relative sliding speed is generated in each tooth surface of the rotating grindstone gear 1 and the processed gear 2 by the axis crossing angle, and the material of the tooth surface 14 of the processed gear 2 is minutely removed by the grinding wheel gear 1. Then, honing processing is performed.

As described above, the gear 2 to be machined has some eccentricity error with respect to the rotation center Q as described above (for example, see FIG. 3), and the pitch having a pitch error waveform. There is an error (for example, see FIG. 22). When the work gear 2 is rotated while meshing with the grindstone gear 1, a rotation error occurs in a rotation error waveform having a pitch of one rotation of the work gear 2 (for example, FIG. 2 described above).
3). Therefore, even after honing, the gear 2
Is rarely corrected (see, for example, FIG. 24).

However, in the fourth embodiment of the present invention, as described above, in addition to the sensors 5 and 6 for detecting the rotation angles (or rotation speeds) of the grinding wheel 1 and the work gear 2, the control means 7
Rotation deviation calculating means 8, control command value output means 11,
A position signal generating / transmitting means 12 is provided.

For this reason, the rotation deviation calculating means 8 detects the deviation of the rotation angle (or rotation speed) of the gear 2 to be honed by rotating at a constant speed in relation to its rotational position, and calculates the deviation. Calculate phase and amplitude. Here, a rotation deviation waveform 16 having a pitch of one rotation of the processed gear 2 is obtained (for example, see FIG. 16).

Next, the control command value output means 11 presets the rotation angle positions of the motors 3 and 4 of the grinding wheel 1 and the work gear 2 based on the information in the rotation deviation calculating means 8. The relationship, that is, the value for changing to the start phase of the position setting model and the value for changing the feedback gain can be output.

That is, by analyzing the rotational deviation waveform 16, a sine waveform 17 having a pitch of one rotation of the gear 2 to be processed is extracted (see, for example, FIG. 17), and the amplitude A of the sine waveform 17 is obtained. From the phase difference と, a position signal waveform that determines the amplitude B obtained as a function of the amplitude A, the rotation reference position of the work gear side motor 4 and the start position of the grinding wheel gear side motor 3 is obtained (for example, FIG. 18 described above). reference).

The position signal waveform 25 (for example, as shown in FIG. 18)
Is a rotation deviation waveform 16 (for example, see FIG. 16).
You may make it produce directly from. The start position may use the zero position of the position signal waveform 25 or may use the middle position.

Then, in the position signal creating / transmitting means 12,
A position signal is created using the start phase change value s of the position setting model in the control command value output means 11 and the signal is transmitted to the motors 3 and 4 of the grinding wheel 1 and the gear 2 to be machined. At the same time, the gain command means 13 uses the feedback gain change value t from the control command value output means 11 to generate the grinding wheel gear side motor 3 or the work gear side motor 4.
To the gain command.

As described above, the deviation of the rotation angle (or rotation speed) of the work gear 2 rotating at a constant speed while meshing with the grinding wheel 1 rotating at a constant speed is detected in relation to the rotation position. Based on the information, the rotation reference position of the work gear side motor 4 and the start position of the grinding wheel gear side motor 3 are respectively controlled by the start phase change value of the position setting model, and the grinding wheel side Control is performed so as to cancel an error generated in the motor 3 or the motor 4 on the side of the gear to be processed.

Therefore, even if the gear 2 to be machined has an eccentric error of the gear center O with respect to the rotation center Q and a cumulative pitch error occurs, a rotational deviation occurs when the gear 2 is rotated while meshing with the grinding wheel 1. Even in such a case, the relationship between the grindstone gear 1 and the work gear 2 is controlled according to a predetermined position setting model, and the honing is performed thereunder.

Thus, as the honing is advanced by the gear honing machine according to the present invention, the rotational deviation and the accumulated pitch error of the gear 2 to be processed are reduced (see, for example, FIG. 19), and the tooth surface 14 is reduced. Correction and correction are performed, and high-precision gear processing is performed.

The adjustment signal waveform 18 can also be obtained from the rotation deviation waveform 16 without passing through the sine waveform 17, and the arithmetic means using Fourier analysis and the like are the same as those of the present invention. First, second and third control means 7
May be performed in the same manner as described above.

An embodiment provided with the control means 7 shown in FIG.

In this embodiment, the mechanism is almost the same as the conventional one. As shown in FIG. 1, a work gear 2 and a grindstone gear 1 which is in contact with the work gear 2 at the outer peripheral portion are separated from each other.

As is clear from the above, the gear honing machine according to the present invention has a relatively simple structure,
By making it possible to optimally control the rotation angle (or rotation speed) of the work gear or the grindstone gear, highly accurate gears can be efficiently manufactured.

That is, in the gear honing machine, the connection shaft between the grinding wheel and the gear to be processed and each motor, the intermediate gear device, the grinding wheel and the motor itself have an elastic effect in the rotating direction. ing. Therefore, the gear center of the gear to be processed has an eccentricity error with respect to the rotation center, and a cumulative pitch error occurs. It is difficult to perform honing with a given allowance, and the accumulated pitch error is rarely improved / corrected even after honing the gear to be processed.

On the other hand, the first, second and third embodiments of the present invention
The gear honing machine detects a change in the rotation angle (or rotation speed) of at least one of the grinding wheel and the processed gear, and based on the information, determines the deviation of the rotation angle (or rotation speed) of the motor. There is provided a deviation calculating means and an adjusting value calculating means for calculating, and an adjusting signal command means for transmitting information from the adjusting value calculating means to at least one of the motors.

Thus, the rotation angle of the gear to be machined with respect to the theoretical rotation angle (rotational speed) of the gear to be machined which is calculated in inverse proportion to the gear ratio from the rotation angle (or rotation speed) of the grinding wheel. (Or rotational speed) can be detected in relation to the rotational position of the processed gear, and based on the information, the rotational angle (or rotational speed) of at least one of the motor of the processed gear and the grinding wheel gear can be theoretically determined. Is calculated as information to adjust for the typical rotation angle (or rotation speed),
The signal amount to be adjusted is calculated, and the rotation can be adjusted by instructing the adjustment signal to the motor.

Therefore, even when the gear to be machined has an eccentric error with respect to the center of rotation of the gear and a cumulative pitch error to cause a rotational deviation, the rotational position of the grinding wheel gear and the gear to be machined depends on the mutual rotational position. The rotation of at least one of the grindstone gear and the gear to be processed can be adjusted to a value approximate to the theoretical rotation angle (or rotation speed). As a result, it is possible to reduce and correct the rotational deviation and the accumulated pitch error of the gear to be processed by the honing processing, thereby performing high-precision gear processing and manufacturing a gear that reduces noise at the time of meshing. .

In the fourth aspect of the present invention, while rotating the grinding wheel gear side motor at a constant speed, the rotational angular positions of the motor and the gear wheel to be machined are set in a predetermined relationship, that is, a predetermined relationship. In order to control by the position setting model, there are provided a rotation deviation calculating means, a control command value output means, a position signal creation / transmission means, and a gain command means.

For this reason, the deviation of the rotation angle (or rotation speed) of the work gear that rotates at a constant speed while meshing with the grinding wheel rotating at a constant speed is detected in relation to the rotation position, and its information is detected. Based on the start phase change value of the position setting model sent on the basis of, the rotation reference position of the work gear side motor and the start position of the grinding wheel gear side motor are each controlled, and the feedback gear change value makes the work gear side motor Alternatively, the motor on the grinding wheel side is controlled.

Therefore, even if the gear is a processed gear in which the center of the gear has an eccentric error with respect to the center of rotation and a cumulative pitch error occurs, a rotational deviation occurs when the gear is rotated in mesh with the grinding wheel. The relationship between the grindstone gear and the gear to be processed is controlled according to a predetermined position setting model, and honing can be performed under the model.

As a result, as the honing is advanced by the gear honing machine according to the present invention, the rotational deviation and the accumulated pitch error of the gear to be processed are reduced, and the tooth surface is corrected and corrected. High-precision gear processing will be performed. In addition, honing at high speed can be performed by controlling the motor with the feedback gain change value.
