Powder metallurgy miniature gear has become one of the key structural parts in manual transmission

The manual transmission is a variable speed device used to change the speed and torque of the engine transmitted to the driving wheel. Guangdong macro new material discovered that gear transmission is often use the different number of teeth of powder metallurgical micro gear meshing transmission to realize the change of rotational speed and torque, the principle, a different number of powder metallurgical micro gear meshing transmission can change, and two powder metallurgical micro gear speed is inversely proportional to the number of it.

t can be seen from above that powder metallurgy miniature gear has become one of the key structural parts in manual transmission. For example, the metal powder injection molding manufacturer found that the manual transmission's requirements on its strength, improvement of economy and performance, etc., showed that the load of the powder metallurgy miniature gear was the high-energy stress generated at or near the surface. Therefore, it did not need the whole part to reach the full density. Generally, the powder metallurgy miniature gear bears the profit of impulse when meshing, and the stress peak value is located near the gear surface. Therefore, the powder metallurgy miniature gear mainly needs high strength and high abrasion resistance on the surface or close to the surface.

In general, if the assembly shape component of powder metallurgy miniature gear is not accurate, it may reduce its service life and load capacity, and increase noise. Therefore, the general transmission of the powder metallurgy miniature gear quality requirements are high, usually higher than DIN7.
