Description

Take buffer function's step motor gear structure

Technical Field

The application relates to the technical field of gears, in particular to a gear structure of a stepping motor with a buffering function.

Background

Gear refers to a mechanical element on a rim with gears continuously engaged to transmit motion and power. The use of gears in transmissions has long emerged. At the end of the 19 th century, the principle of generating the gear cutting method and the successive appearance of special machine tools and cutters for cutting teeth by using the principle pay attention to the smoothness of the operation of gears along with the development of production, and the gears can be classified according to tooth profiles, gear shapes, tooth trace shapes, surfaces where gear teeth are located, manufacturing methods and the like, wherein the tooth profiles of the gears comprise tooth profile curves, pressure angles, tooth heights and displacement. Involute gears are easy to manufacture, so that in the gears used in modern times, involute gears account for the absolute majority, cycloid gears and arc gears are less in application, and the bearing capacity of small-pressure angle gears is smaller in the aspect of pressure angles; however, the large pressure angle gear is used only in special cases because the load of the bearing increases when the transmission torque is the same, although the load capacity is high. The tooth height of the gear is standardized and generally adopts the standard tooth height. The advantages of the modified gears are many, and the modified gears are distributed in various mechanical equipment.

The gear in the prior art is lack of a buffer mechanism, and the situation of tooth breakage often occurs in the use process, so that the motor is in failure, and the motor is seriously damaged.
