炭焼入れ等の熱処理を施して硬化させて製作している。l Uncut and uncut Power transmission gears used in various machine tools, automobiles, etc. are made by cutting the material with a gear cutting machine, etc., and then finishing the tooth surface with a gear grinding block or shaving machine. It is manufactured by hardening it through heat treatment such as carburizing and quenching.

傷による突起（３）を研削して修正してやる必要がある
。By the way, when manufacturing the above gears, if you perform finishing processing after heat treatment, you can obtain highly accurate gears. Machining requires very expensive equipment and costs are high, so finish machining is usually performed with the tooth surface unhardened.Therefore, product management is required after finish machining until heat treatment is applied. However, even if product management is strict, gears (as shown in Figure 4) may occur for some reason during or before heat treatment.
Bruises were sometimes caused on the tooth surface (2) of 1). The protrusions (3) caused by such bruising cause problems such as making abnormal noises during engagement and causing noise, so it is necessary to repair the protrusions (3) caused by the bruising by grinding after heat treatment.

In addition, in a shaving machine, the center axis of the processing tool is slightly inclined with respect to the center axis of the gear to be processed, and the tool and the gear to be processed are brought into sliding contact for grinding. However, if multiple gears are damaged in multi-stage gears, such as those used in automobile transmissions, it is not possible to repair all the gears at the same time, and multiple shaving machines are required. ,
The equipment is large and expensive. Therefore, correction of the multi-stage gear as described above had to be done manually, resulting in poor workability.

を除去する。The correction device (8) having the above structure is arranged so that the central axis of the processing tool (11), that is, the central axis of the support shaft (10) is parallel to the central axis of the gear to be processed (5). Then, both ends of the rotating shaft (6) of the gear to be processed (5) are rotatably supported, and then the slide lock is moved to move the correction device (8) in the orthogonal direction, and the processing tool (11) is rotated. Suba (27)
(28) meshes with the helix (7) of the gear to be machined (5). At this time, the meshing pitch circle between the machining tool (11) and the gear to be machined (5) is made to be at the root of the tooth of the gear to be machined (5). After this, the gear to be machined (5) is connected to the rotating shaft (6).
This causes the machining tool (11) to rotate in a driven manner, and the tooth surface of the helical gear (7) of the to-be-processed gear (5) is ground by the meshing of both (11) and (5), resulting in damage. Remove protrusions.

(2B>), since there is sliding contact over the entire area, it is possible to remove protrusions generated on the teeth (7) of the gear to be machined (5).In addition, in the above embodiment, two gears to be machined (25) (2
6) is used to correct both shoulders of the tooth (7) of the gear to be machined (5), but - number of machined gears are used and these are meshed with the entire surface of the teeth of the gear to be machined. Furthermore, in the above embodiment, a single gear to be machined is modified, but when there are multiple gears to be machined on the rotating shaft (6). , a plurality of processing tools (11) are provided on the spindle (10), and each processing tool (
11) may be corrected by meshing with the corresponding gear to be machined.

備費も安価になる。1. In the repairing device of the present invention, the gear to be machined and the processing tool come into sliding contact over the entire contact surface, so it is possible to reliably repair the damage caused on the tooth surface of the gear to be machined. Since the center axis of the gear to be machined and the center axis of the processing tool are arranged parallel to each other,
Even if multiple gears are damaged in multi-stage gears such as those used in automobile transmissions, multiple machining tools are placed on the same axis in correspondence with the gears that need to be repaired, and these tools are connected to the gears to be machined. By meshing with the gears, multiple gears to be machined can be repaired simultaneously with one repairing device, making it possible to automate the repair of scratches on multi-stage gears, which was previously considered impossible, and making the entire device more compact. The cost will also be lower.
