1. Selection of gear and rack: the modulus is the value indicating the shape and size of the tooth shape of the gear. The bonding transmission can be carried out only when the modu

The national standard specifies 13 Accuracy grades for gear pairs for gears. Use Arabic numerals 0, 1, 2 The accuracy of each level is 12, and the accuracy of the rest is the lowes

Gears can be classified according to tooth profile, gear shape, tooth line shape, surface of gear teeth and manufacturing method, as follows: 1. Gears can be classified into tooth

The gear rack will have its own unique motion characteristics in the transmission process: the gear transmission is used to transmit the motion and power between any two shafts. It

The tooth profile of the rack is a straight line rather than an involute (plane for the tooth surface), which is equivalent to a cylindrical gear with an infinite radius of the ind

A large transmission ratio can be obtained, which is tighter than the staggered shaft helical gear mechanism The meshing tooth surfaces of the two wheels are in line contact, and i

The worm material is mainly carbon steel or alloy steel, which should have special properties such as high strength, high toughness, wear resistance, corrosion resistance, low temp

Structural features of worm gear reducer: It can obtain a large transmission ratio and is more compact than the staggered shaft helical gear mechanism. The meshing tooth surfaces o

The worm gear is used for the rotation between two cross shafts (the cross angle is generally right angle). Generally, the worm is driven and the worm gear is driven. It is used fo

Classification of copper alloys and their Applications Commonly used copper alloys are divided into three categories: brass, bronze and cupronickel Its features are as follows: 1)B

Copper Alloys Features: Copper alloy is an combination formed by adding one or several other elements to pure copper. The pure copper is purplish red, also known as purple copper.

Air quick coupler As we know air quick coupler is different from hydraulic quick coupling from the following points: 1. The application field they used is different, because the pr
