When making bevel gears, the biggest problem is the method of making the teeth. Small wooden bevel gears used in clocks, automatic devices and other objects should be cut from pieces of wood and used for waterwheels and other objects. Above, because the wooden bevel gears related to power have to bear the load, they must have strength requirements. When the teeth of the bevel gear wear, they also need to be repaired.

How has the bevel gear improved so far?

Metal spiral bevel gears were originally processed by hand in Europe. However, with the change of the 8-blade tooth profile, the difficulty of drawing has increased. The first machined bevel gear is the bevel gear for clocks, which is 18 It was processed and formed at the beginning of the century, and the actual object is still kept in the Stockholm Museum, Sweden. The processing method is to file the teeth one by one through the up and down movement of the file in the cross section of the tooth groove shape. The manufacturer is the Swedish Bo Elham. After that, the tool for rotating the alveolar shape of the Sacramento Basanson valve in France is a tool that is better than filing and similar to a rotary file.

Bevel gear

After entering the 19th century, milling cutters began to be used to process bevel gears. Bodmore in Switzerland and Witworth in the United Kingdom have made this record. Because the relief cutter was not invented at that time, the service life of milling cutters is generally not long.

Soon, many manufacturers have successively developed various gear cutting machines which can be called automatic cutting equipment, and then developed the generative gear cutting method.
