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 of the first embodiment has 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 spiral grindstone in which the angle of the teeth of the helical toothed grindstone is increased is used. In addition, the grindstone 2 uses an elastic material that can deform 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 width of the tooth groove of the gear W to be machined. The grindstone 2 is rotatably supported by the attachment base with the rotation axis C as a rotation center (the figure is omitted).

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

Embodiment approach 2

[0090] The tooth surface processing device of the second embodiment has basically the same structure and effects as the tooth surface processing device 10 of the first embodiment. Hereinafter, the description will focus on the different structures and effects.

[0091] The adjustment member 9 of the tooth surface processing device of the second embodiment is different from the adjustment members 52 and 8 used in the tooth surface processing device 10 of the first embodiment. The adjusting member 9 used in the tooth surface processing device of the second embodiment is such as 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 state rotatable with respect to the bearing portion (not shown). The adjustment member 9 has a torque generating motor 91 that generates torque at the other end, and has a first measuring member 92, a second measuring member 93, and a torsional vibration damping body 94...

Embodiment 1

[0098] Here, Picture 10 It is a figure which shows the system structure of the tooth surface processing apparatus of this Example 1. In addition, Picture 10 The tooth surface processing device of Example 1 exemplified in the above is a device in which the grindstone 2 and the gear W to be processed rotate synchronously.

[0099] In the tooth surface processing device of the first embodiment, a grindstone rotating motor 4 as a spindle motor is connected to the grindstone 2, and the spindle motor 4 can be used to drive the helical grindstone 2 to rotate. In addition, a built-in detector 4a is provided in the spindle motor 4, and the rotation amount of the grindstone 2 can be grasped. On the other hand, the gear to be machined W is connected to the servomotor 18 for driving via the C-axis 16 and the timing belt 17, and the gear to be machined W can also be driven to rotate by the servomotor 18 for driving. Furthermore, the grindstone 2 connected to the spindle motor 4 and the gea...

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, and in particular to a tooth surface processing device and a gear manufacturing method for finishing the tooth surface of a high-hardness gear using a helical grindstone. Background technique [0002] It is well known that if the surface roughness of the tooth surface of the gear is improved (the surface roughness is reduced), the durability, transmission efficiency, and noise of the gear can be improved. [0003] Among the methods of finishing the tooth surfaces of high-hard gears, the mainstream method is to forcibly rotate the tooth root surface of the high-speed rotating spiral grindstone and the machined gear synchronously while simultaneously finishing the two tooth surfaces of the machined gear. Efficient gear grinding method for machining. In the gear grinding method, meshing is performed in a state where the gap between the tooth root surface of the g...
