Large-scale high-precision spiral bevel gear machining technology requires three necessary conditions

In theory, the large-scale high-precision spiral bevel gear machining technology requires three necessary conditions, namely the determination of the pressure parts, the determination of the helix angle and the cutting of the tool radius. They are the basic structure of the gear, in terms of the radius of the cutter head, pay attention to the installation position. The installation of the cutter head is mainly based on the rotation of the cutter body, and the oblique line is the side view. The movement of the tool is also an important part. It is a technical method of a parallel device with an eccentric roller as the core, and special attention should be paid to the position of the tool. This is based on the fan-shaped turntable, with the moving parts box as the carrier, and is processed in the axial direction. It is also important to adjust the position of the cutter head. Each knife face has a balanced cross-section, and the location of the cross-section point is the center of the machine that carries the machining gear. The manufacturer should move along the axis of the bed base and install the sector overall shape on the rollers. The installation standard should be carried out with the angle of the Bell gear adjusted according to certain parameters. This parameter is mainly obtained by the mechanical gear on the milling machine. We use designed gearing.

Refers to the use of rotating multi-blade tools to cut the workpiece for processing. During horizontal milling, the formation of the plane is formed by the edge on the outer surface of the milling cutter. In end milling, the plane is formed by the end face edge of the milling cutter. Milling is generally carried out on a milling machine or a boring machine, and is suitable for processing planes, grooves, various forming surfaces (such as splines, gears and threads) and special shapes of molds.

Tooth surface machining methods can be divided into two categories: forming method and generating method. The forming method is a method of machining a workpiece with a forming tool. Among them, tooth milling is commonly used—a method of directly cutting gear teeth on a milling machine with a forming gear milling cutter (disk-shaped or finger-shaped milling cutter). The machine tool used to process the tooth surface by the forming method is generally an ordinary milling machine, and the tool is a forming milling cutter, which requires two simple forming movements: the rotational movement of the tool and the linear movement.
