External diameter 189* Internal diameter 90* high 40* hole 14 50 teeth
gear 1614930100 OD 159* OD 75* H 40* hole 14 42 teeth,is a set ,classificationGear tooth profile can be, the gear shape, tooth shape, tooth surface and manufacturing methods such as classification.Tooth profile curve of gear tooth profile including, pressure Angle, depth and deflection.Involute gear is relatively easy to manufacture, so the modern use of gear involute gear majority, with less cycloidal gear and circular-arc gear applications.
In the aspect of pressure Angle, the bearing capacity of small pressure Angle gear smaller; And pressure Angle of gear, though bearing capacity is higher, but under the same in the transmission torque of bearing the load increase, so only for special situations. And gear tooth depth has been standardized, generally adopt high standard tooth. The advantage of deflection gear is more, in all kinds of mechanical equipmentIn addition, the gear can also according to its shape can be divided into cylindrical gear, bevel gear, the non-circular gear, rack, worm, worm gear; According to the tooth line shape can be divided into straight gears, helical gears, herringbone gear, gear curve; According to the tooth's surface is divided into external gear and internal gear; According to the manufacturing method can be divided into casting rolling gear, gear, gear cutting, sintered gear, etc.
materialCommonly used steel manufacturing gear 1614930100 quenched and tempered steel, hardened steel, chlorine steel carburizing and quenching steel and permeability. Slightly lower than the strength of the cast steel forging steel, used to size the larger gear; Mechanical properties of gray cast iron is bad, can be used for the open gear transmission in light load; Nodular cast iron can partially replace steel manufacturing gear; Plastic gear is used for light load and more requirements of low noise, and its gear pairs, the thermal conductivity is commonly used in steel gears.
