Hard-toothed Gear/Bevel Gear/Helical Gear/Spiral Gear/Reducer Gear
Product Features
A gear is a component in mechanical transmission that transmits power through the meshing of teeth. It can be classified into types such as spur gears, helical gears, and bevel gears based on its tooth profile. Its core parameters include the module, diameter, and pressure angle (which affect the meshing characteristics). The meshing must follow the basic law of tooth profile meshing, that is, the transmission ratio is determined by the intersection point of the tangent lines at the contact points and the common center line, and conjugate tooth profiles are formed to ensure a constant transmission ratio.
The design of gears must take into account both bending strength and tooth surface strength, and optimize performance through parameters such as module and number of teeth. During the processing, the displacement technology can be adopted to adjust the tooth thickness and avoid root cutting. Helical gears utilize the helical tooth surface to enhance the transmission stability. The worm gear and worm wheel mechanism is suitable for spatial intersecting shaft transmission, while the conical gears are specifically used for intersecting shaft power transmission. The modern gear standardization system covers precision indicators (such as pitch deviation, radial runout), geometric calculations and classification norms, forming a complete mechanical transmission technology framework.
