Description

Clamping device for machining sector gear

Technical Field

The invention relates to the technical field of sector gear machining, in particular to a clamping device for sector gear machining.

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 cutting method and the successive appearance of special machine tools and cutters for cutting teeth by using the principle pay attention to the running stability of gears along with the development of production. Gears can be classified by tooth profile, gear profile, tooth trace shape, surface on which the teeth are located, and manufacturing method, etc. The tooth profile of the gear includes profile curve, pressure angle, tooth height and profile variation. Involute gears are relatively easy to manufacture, so that in the gears used in modern times, involute gears are the absolute majority, while cycloid gears and circular arc gears are less used. In the aspect of pressure angle, the bearing capacity of the small pressure angle gear is smaller; 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 more, and the modified gears are distributed in various mechanical equipment.

The clamping device is used for clamping the sector gear, the existing clamping device is composed of two clamping plates which are fixed through bolts, and the clamping effect is poor.
