In mechanical transmission systems, gear drives are among the most prevalent power transfer methods. Among these, parallel shaft gear trains and planetary gear systems (revolving gear systems) stand out as two classic configurations, each featuring distinct structural characteristics, transmission a

Shaft components, as the core parts of mechanical transmission systems, directly impact the overall performance and service life of equipment through their assembly accuracy and structural reliability. In over-travel fits, the rational selection and process control of press fitting and cold drawing

When grinding the worm wheel, the key principle of selecting the worm wheel is that the number of worm wheel heads Z1 and the number of teeth of the workpiece Z2 are prime numbers (i.e., no common factors), which is the core reason to avoid periodic engagement error and ensure grinding uniformity.If

The discontinuity of metal materials refers to the non-uniformity and abrupt changes in their internal structure, composition, or properties. In failure analysis cases, it is found that many failures are caused by the discontinuity of materials. The discontinuity of structures is mainly reflected in
