The structure of the gear

　　With the increasingly rapid development of the machinery industry, various types of mechanical equipment emerge in an endless stream. Of course, mechanical parts such as gears are also very important. They are widely used in people's daily lives.So, do you know what structure is such a common mechanical part? Is there a lot of people who don't know it very well? Now let's give you a brief introduction to the structure of gears.Hope, our introduction can be helpful to everyone, let's do some related understanding with the editor below!

　　Gear teeth are abbreviated as teeth, which are each convex part of the gear used for meshing. These convex parts are generally arranged in a radial pattern. The gear teeth on the mating gears are in contact with each other, so that the gears can continuously mesh and operate; the tooth groove isgearThe space between two adjacent gear teeth; the end face is the plane perpendicular to the axis of the gear or worm on the cylindrical gear or cylindrical worm; the normal plane refers to the plane perpendicular to the tooth line of the gear tooth; the addendum circle refers to the top of the tooth The circle where the tooth is located; the root circle is the circle where the groove bottom is located; the base circle is the circle that forms the involute line for pure rolling; the index circle is the reference circle for calculating the geometric dimensions of the gear in the end surface.Gears can be classified according to tooth shape, gear shape, tooth line shape, surface on which the gear teeth are located, and manufacturing method.

　　The tooth profile of the gear includes tooth profile curve, pressure angle, tooth height and displacement.Involute gears are easier to manufacture, so in modern gears, involute gears account for the majority, while cycloid gears and arc gears are less used.In terms of pressure angle, the load-carrying capacity of gears with small pressure angles is smaller; while gears with large pressure angles have higher load-carrying capacity, but the load on the bearing increases when the transmission torque is the same, so it is only used in special cases.The tooth height of gears has been standardized, and standard tooth heights are generally adopted.There are many advantages of displacement gears, which have been used in all kinds of mechanical equipment.The manufacturing material and heat treatment process of the gear also have a great influence on the load-bearing capacity and size and weight of the gear.

　　Should everyone know about the structure of the gear above? Tooth groove, end face, normal surface, addendum circle, etc. are some very important composition structures.
