Because the processing of the tooth surface of the involute gear is difficult to carry out high-precision processing by normal processing means, the invention provides a method for improving the processing precision of the microtexture on the tooth surface of the involute gear by simulating the forming process of the involute gear. Because the rectangular coordinate system is difficult to express the motion relation of the X axis and the Y axis in the involute equation, the XOY plane in the established spatial rectangular coordinate system is converted into a polar coordinate system, and the coordinate elements are the radius r and the rotation angle theta respectively. After the gear 8 is positioned, the processing of the micro texture on the gear tooth surface of the gear 8 is started, after the laser light source 7 is turned on, the servo motor 13 controls the screw rod 12 to rotate, the screw rod 12 drives the base 4 to move along the positive direction of the Z axis, according to the designed micro texture size and the requirement of the clearance D, the gear 8 moves a distance D along the positive direction of the Z axis every time, the laser light source 7 processes a micro texture on the gear tooth surface of the gear 8 until the requirement of the micro texture on the whole gear 8 in the tooth thickness direction is completed, the laser light source 7 is turned off, the servo motor 2 controls the screw rod 11 to rotate, the screw rod 11 drives the base 4 to move along the positive direction of the X axis, the displacement X satisfies the equation X r multiplied by cos (theta + alpha) + (theta + alpha) X multiplied by r multiplied by sin (theta + alpha), wherein r and theta are coordinate elements of a polar coordinate system with the base as the origin on the motion plane, and alpha is the pressure angle of the gear 8, similarly, the vertical plate 5 is driven by the rotary lifting platform 10 to move along the Y axis, the gear 8 is driven by the vertical plate 5 to move along the positive direction of the Y axis, the displacement Y satisfies the equation Y of r × sin (theta + α) - (theta + α) × r × cos (theta + α), wherein r and θ are coordinate elements of a polar coordinate system with the base as the origin of the motion plane, α is the pressure angle of the gear 8, the moving path of the gear 8 is compounded into the involute profile of the gear 8 through the movement of the X axis and the Y axis, then the values of r and θ are determined according to the requirements of the micro-texture size and the clearance D, the path of the compounded gear 8 on the involute profile is D, then the laser light source 7 is turned on, the screw 12 is controlled to rotate by the servo motor 13, the base 4 is driven by the screw 12 to move along the negative direction of the Z axis, the gear 8 moves by a distance of D along the positive direction of the Z axis according to the designed micro-texture size and the clearance D requirement, the laser light source 7 drills a micro-texture on the surface of the gear 8 until the requirement of the micro-texture in the tooth thickness direction of the whole gear 8 is completed, and the like is repeated until the processing of the micro-texture of the tooth surface of the whole gear is completed. The method can lead the laser light source 7 to realize the processing of the microtexture on the reciprocating path of the gear, thereby saving time and reducing energy consumption. When one surface of one gear tooth of the gear 8 is completely processed, the taper spindle 9 is controlled by the servo motor 6 to rotate, the gear 8 is driven to rotate, the rotation angle is 360 degrees/z, and z is the number of teeth of the gear 8. And the operations are repeated in sequence, so that the same surface of the gear teeth on the gear 8 can be completely processed.
If the gear requires to process the micro texture on both sides, the figure shows that after the gear 8 processes one side of all gear teeth, the vertical plate 5 is driven to rotate for 180 degrees by rotating the lifting platform 10, the rest positions are ensured to be unchanged, the unprocessed side of the gear teeth of the gear 8 is placed in the laser light source 7, and the processing steps are repeated to complete the processing of all the sides.
After the gear 8 is subjected to micro texturing on the gear surface, although the surface roughness of a friction pair is reduced, the friction factor of the gear surface can be reduced, and the tooth surface abrasion is reduced, so that the meshing precision of the gear pair is improved. Meanwhile, as the meshing precision of the contact area of the gear 8 is improved, the vibration, noise, heat dissipation and material migration of the gear pair formed by the gear 8 are improved, so that the service life of the gear 8 processed by the micro-texture laser is greatly prolonged. The method for improving the machining precision to improve the performance and the service life of the workpiece by changing the machining mode has important implementation significance for the actual requirement of urgent leap-type development at the present stage of China.
The above embodiments are only used for illustrating the design idea and features of the present invention, and the purpose of the present invention is to enable those skilled in the art to understand the content of the present invention and implement the present invention accordingly, and the protection scope of the present invention is not limited to the above embodiments.

The method for processing the microtextured surface of the tooth of the involute gear with high precision according to claim 6, wherein after the surface of one gear tooth 8 is processed, the taper spindle 9 is controlled to rotate through the servo motor 6, the gear 8 is driven to rotate by the taper spindle 9, and the surface of the gear tooth to be processed of the gear 8 is rotated to the focal position of the laser light source 7, so that the microtexture processing of the next surface of the gear 8 can be performed.
8. The method for processing the microtextured surface of the tooth of the involute gear with high precision according to claim 7, wherein after one side of all the teeth of the gear 8 is processed, the other side of all the teeth of the gear 8 can be processed only by controlling the rotary lifting platform 10 to rotate 180 degrees.
9. The method for laser processing the micro-texture on the tooth surface of the involute gear with high precision according to claim 7, wherein the position and the output power of the laser light source 7 are kept constant during the processing of the gear 8, and the discrete processing is performed to ensure the processing precision of the micro-texture on the tooth surface of the gear.
