Description

【Technical field】 [0001] The invention belongs to the technical field of powder metallurgy, and in particular relates to a novel powder metallurgy transmission gear. 【Background technique】 [0002] Gears are wheel-shaped mechanical parts that rely on the meshing of teeth to transmit torque reliably and without noise. Through transmission with other toothed mechanical parts, gears can achieve functions such as changing speed and torque, changing motion direction, and changing motion form. At present, gear transmission has become the most widely used transmission method. [0003] Powder metallurgy technology can produce parts requiring high dimensional accuracy and complex shapes in a shape very similar to the shape of the product, which can greatly reduce cutting costs. Especially in the field of gear manufacturing, gear manufacturing by powder metallurgy is an efficient, precise and flexible metal processing technology, which is suitable for mass production of high-strength...
