Jinhua heavy truck cylindrical gear classification:
1, according to the tooth shape of Jinhua heavy truck cylindrical gear: including tooth profile curve, pressure Angle, tooth height and displacement. Involute gears are relatively easy to manufacture, so in the gears used in modern times, involute gears account for the majority, while cycloidal gears and arc gears are used less.
2, according to Jinhua heavy truck cylindrical gear is the pressure Angle: small pressure Angle gear carrying capacity is small; The large pressure Angle gear, although the bearing capacity is higher, but the bearing load increases in the case of the same transmission torque, so it is only used in special cases. The tooth height of the gear has been standardized, and the standard tooth height is generally used. Variable gear has many advantages and has been used in all kinds of mechanical equipment.
3, according to the shape of Jinhua heavy truck cylindrical gear: divided into cylindrical gear, bevel gear, non-circular gear, rack, worm gear; According to Jinhua heavy truck cylindrical gear tooth line shape is divided into spur gear, helical gear, herringbone gear, curve gear; According to the surface of the gear teeth are divided into external gear and internal gear; According to the manufacturing method, it can be divided into casting gear, cutting gear, rolling gear, sintering gear, etc.
