  • Structure for standardizing parts of a roller assembly for a construction vehicle
    Patent number: 6851768
    Abstract: A structure for standardizing at least one kind of part of a roller assembly for a construction vehicle so that the part can be used for a same size of construction vehicles having different structural specifications of a plurality of construction vehicle makers. The at least one kind of part includes at least one of a shell, a shaft, a floating seal, a bushing and a collar. Structural specifications including the configuration and dimension, the kind of steel or material, and the heat treatment specification or the mechanical property for the at least one kind of part are unified as much as possible over the same size of the construction vehicles of a plurality of construction vehicle makers.

  • Production method of a heat-treated steel member
    Patent number: 6294031
    Abstract: A production method of a heat-treated steel member includes the steps of: shaping a steel material of low-carbon boron steel containing about 0.05-0.30% carbon by weight into a predetermined configuration to bc a shaped material; and heat-treating the shaped material, said heat-treating, includes quench-hardening only.
