Description

  The present invention relates to a gear deburring device, a gear chamfering device, and a gear deburring method for removing burrs generated on a tooth surface of a gear.

  In gear processing, chamfering is performed with a gear chamfering tool on a gear to be cut by a hobbing machine or the like in order to prevent dent scratches and lacerations of workers. Chamfering is a rolling process in which a gear chamfering tool is pressed against the tooth profile ridge line, which is the corner between the gear end face and the gear tooth surface, and the tooth profile ridge line is crushed. Protrudes toward the gear end face side and the gear tooth face side to form burrs. This burr is also removed because it may cause dents and lacerations in production.

  The burr generated on the end face of the gear is removed using a disc-shaped end face deburring cutter. For the purpose of rationalizing gear machining and reducing equipment, an end face deburring cutter is installed in the vicinity of the gear chamfering tool, and chamfering with a gear chamfering tool and end face deburring with an end face deburring cutter are performed on the work gear. It is common to apply.

  About the burr | flash produced on the gear tooth surface, it is made hard to produce a big burr | flash by devising a chamfering shape, and only a micro burr | flash is produced. In addition, there is no particular step for removing minute burrs, and minute burrs generated on the gear tooth surfaces are removed when the gear tooth surfaces are cut or polished in a finishing process or a polishing process, which is a subsequent process. I am doing so. However, removing fine burrs with a gear finishing tool or gear grinding wheel locally increases the wear of the gear finishing tool or gear grinding wheel at the location, and shortens the replacement cycle of the gear finishing tool or gear grinding wheel. Resulting in.

  Therefore, it is conceivable to add a new process for performing a tooth surface deburring process for removing burrs generated on the gear tooth surfaces of the work gear. However, in order to add a new process, not only the tooth surface deburring burnishing gear for removing the burr generated on the gear tooth surface, but also a device for performing the tooth surface deburring process and the installation space for the device are required. This leads to an increase in gear processing equipment costs.

  In addition, the tooth surface deburring process is installed together with the chamfering process and end face deburring process by adding the tooth surface deburring burnishing gear to the equipment that performs chamfering process and end face deburring process. It is conceivable to apply machining. However, it is difficult to secure a space for moving the three gear tools back and forth to the machining position of the work gear by installing three gear tools, a gear chamfering tool, an end surface deburring cutter, and a tooth surface deburring burnishing gear. In particular, in gear processing equipment that incorporates chamfering and end face deburring processes into hobbing machines that perform gear cutting, the installation space for tooth deburring burnishing gears is even more severe. Enlarging the device to secure space leads to an increase in gear processing device cost.
