Embodiment Construction

[0043] a. The disc-shaped gear chamfering cutter is composed of several V-shaped cutting surfaces (file surfaces) in the working part. The intersection line between the cutting surface and each section is theoretically formed by the involute formed by the same base circle, and the two cutting surfaces respectively resemble the tooth surfaces of left-handed and right-handed cylindrical helical gears.

[0044] b. When the disc-shaped gear chamfering cutter is cutting, several V-shaped filing surfaces are in contact with the edges of the gear tooth profile alternately. The cutting process is similar to the filing process of a file.

[0045] c. The axis of the chamfering knife is parallel to the axis of the gear being machined. During the meshing process of the tool and the gear, the edge cutting process is performed by using the relative sliding between the tooth surfaces and the axial feed pressure.

[0046] d. Regardless of whether it is chamfering the tooth profile of a spur ...

Abstract

The invention relates to a gear machining process applicable to tooth contour chamfering after gear machining. The gear machining process is mainly used for chamfering in the case that gear end surfaces of duplicate gears, shaft gears and the like which have small chamfering distances are influenced by other structures and cannot be chamfered by other chamfering tools. The invention specifically relates to a disc-shaped toothing gear chamfering knife for tooth contour chamfering for a cylindrical gear, and a manufacturing method. The disc-shaped toothing gear chamfering knife is disc-shaped, and a working part is composed of a plurality of V-shaped toothing surfaces formed on the circumference of a disc; the intersection line of each toothing surface and each section is theoretically composed of an involute formed by the same base circle; and two cutting surfaces are similar to tooth surfaces of a left-hand cylindrical helical gear and a right-hand cylindrical helical gear separately.The disc-shaped toothing gear chamfering knife is a special tool for end surface edge chamfering for gears, and the tool is easy to manufacture and has no special requirements on equipment; proper rotation speed, feeding amount and feeding speed are set; and the tool is good in chamfering effect, free from burrs, and capable of obtaining uniform edges.

Description

technical field [0001] The invention relates to a gear processing technology, which is suitable for tooth profile chamfering after gear processing, and is mainly used for the case where the end faces of gears such as duplex gears and shaft gears with small spacing are affected by other structures and cannot be chamfered by other chamfering tools. Specifically, the invention relates to a disc-shaped gear chamfering cutter for tooth profile chamfering of a cylindrical gear and a manufacturing method thereof. Background technique [0002] Single-piece gears can be chamfered by hobs and grinding wheels on the edges of the gear end faces. For double gears, because there is not enough turning space, disc-shaped edge-extruding cutters can be used for processing. However, it is difficult to manufacture disc-shaped edge knives, the price is high, the adjustment time is long, and the purchase price is relatively high due to the complex structure of the machine tool. Therefore need a...
