Problems solved by technology

However, as shown in Patent Document 1, the gear honing method is a method in which the tooth surfaces of the grinding stone and the gear are meshed with zero clearance to process both tooth surfaces at the same time, so it is difficult to finely control the tooth surface of the grinding stone and the teeth of the gear to be machined. Processing pressure between faces

Embodiment approach 1

[0063] Such as figure 1 As shown, the tooth surface processing device 10 according to Embodiment 1 includes a grindstone (helical-toothed grindstone) 2, a position adjustment mechanism 3, a grindstone rotation motor (grindstone rotation mechanism) 4, a rotation torque control mechanism 5, and a control mechanism 7.

[0064] As the grindstone 2, a helical grindstone in which the angle of the teeth of the helical grindstone becomes large is used. Furthermore, the grindstone 2 is made of an elastic material capable of deforming the grindstone tooth surface 21 along the shape of the processed tooth surface 11 of the gear W to be processed. The tooth thickness of the grindstone 2 is smaller than the tooth groove width of the gear W to be machined. The grindstone 2 is rotatably supported by an attachment base (not shown) with a rotation axis C as a rotation center.

[0065] The grindstone rotation motor 4 rotates the grindstone 2 around the rotation axis C via a speed reduction m...

Embodiment approach 2

[0090] The tooth surface machining device according to the second embodiment has basically the same configuration and effects as those of the tooth surface machining device 10 according to the first embodiment. Hereinafter, a description will be given centering on different configurations and effects.

[0091] The adjustment member 9 of the tooth surface machining device according to the second embodiment is different from the adjustment members 52 and 8 used in the tooth surface machining device 10 according to the first embodiment. The adjustment member 9 used in the tooth surface machining device of the second embodiment is as follows: Figure 8 As shown, one end is inserted into the gear W to be processed, and the other end 614 side of the shaft portion 61 is provided in a rotatable state with respect to a bearing portion not shown in the figure. The adjustment member 9 has a torque generating motor 91 that generates torque at the other end, and has a first measuring memb...

Embodiment 1

[0098] here, Figure 10 It is a figure which shows the system structure of the gear surface machining apparatus of this Example 1. also, Figure 10 The tooth surface machining apparatus of Example 1 exemplified in FIG. 1 is an apparatus in which the grinding stone 2 and the gear W to be machined rotate synchronously.

[0099] In the tooth surface processing apparatus of the first embodiment, the grindstone 2 is connected to the grindstone 2 with the grindstone rotation motor 4 as a spindle motor, and the helical grindstone 2 can be driven to rotate by the spindle motor 4 . In addition, the spindle motor 4 is provided with a built-in detector 4 a so that the amount of rotation of the grindstone 2 can be grasped. On the other hand, the gear W to be processed is connected to the drive servomotor 18 via the C-shaft 16 and the timing belt 17 , and the gear W to be processed can also be driven to rotate by the drive servomotor 18 . Furthermore, the grinding stone 2 connected to t...

Abstract

A gear tooth surface processing device and a gear manufacturing method are provided which are capable of adjusting processing pressure for the purpose of improving the surface roughness of high-hardness gears and the like. The gear tooth processing device (10) has: a helical grindstone (2); a position adjusting means (3) which is capable of moving the relative positions of a rotary axis (C) of the helical grindstone (2) and a rotary axis (X) of a gear to be processed (W); and a control means (7). The control means (7) includes: a position control unit (71) which operates the position adjusting means (3) so as to adjust the relative positions of the rotary axis (C) of the helical grindstone (2) and the rotary axis (X) of the gear to be processed (W) to cause only one of the tooth surfaces to be processed (11), from among the gear tooth surfaces that form a single tooth of the gear to be processed (W), to make contact with a grindstone tooth surface (21) of the helical grindstone (2) such that the helical grindstone (2) and the gear to be processed (W) are engaged; a grindstone rotation means control unit (72) for operating a grindstone rotation means (4); and a torque control means control unit (73) for operating a rotation torque control means (5) so as to adjust the rotation torque within a predetermined range.

Description

technical field [0001] The present invention relates to a tooth surface processing device and a gear manufacturing method, in particular to a tooth surface processing device and a gear manufacturing method for finishing the tooth surface of a high-hardened gear using a helical-toothed grindstone. Background technique [0002] It is well known that if the surface roughness of the tooth surface of a gear is improved (reduced surface roughness), the durability, transmission efficiency, and noise of the gear can be improved. [0003] In the method of finishing the tooth surface of the high-hardened gear, the mainstream method is to simultaneously finish the two tooth surfaces of the processed gear while forcing the dedendum surface of the high-speed rotating helical grindstone to rotate synchronously with the processed gear. Efficient gear grinding method for machining. In the gear grinding method, meshing is performed in a state where the gap between the dedendum surface (grin...
