Title: Manufacture of rolling parts made of steel, excellent in rolling fatigue strength, and rolling parts
Inventor: OTANI KEIZO
IPC: C22C38/50
Filed: 1999-02-24
Abstract: PROBLEM TO BE SOLVED: To provide rolling parts for an automobile transmission (gears, rolling elements of a non-stage transmission), having excellent rolling fatigue strength. SOLUTION: An alloy steel with a specific alloy composition is worked into a blank having a shape close to parts shape, subjected to carburizing or carbonitriding and quenching and to tempering, and then preformed into the shape and dimension determined by deducting the plating layer thickness from the final parts shape and dimension and adding the final finish working machining allowance after plating. The hardness of the surface of the resultant preformed part does not fall below Hv 700 even after heating treatment at <=300 deg.C for <=3 hr. Subsequently, NiP plating is applied to the preformed part and heat treatment is applied at <=300 deg.C for 3 hr to regulate the hardness of the NiP plating layer to >=Hv 800. Then, finish working is performed to obtain the final parts shape and dimension.

Abstract: PURPOSE:To cause treating liquid to penetrate into the end or minute portion of the structure of base material, while raising impregnating speed remarkably by a method in which sheetlike base material is deaeration-treated under reduced pressure, while transporting it continuously, and then the base material is impregnated with the modifying agent for the base material under normal atmospheric pressure, and is dried. CONSTITUTION:For instance, a plurality of base materials are deaeration-treated in the deaeration chamber 5 under reduced pressure, after it has passed a pre- reduced pressure-box 4 at the inlet side in the state of combined layers. Then the base material passes the pre-reduced pressure-box 4 at the outlet side in a layer state, and passes through between the coating rolls 6 provided at said outlet. The side plate 9 serving, as a scraper is brought into contact with each coating roll 6, thereby forming a tank receiving the treating liquid on the upper part of the rolls 6. Each base material 1 is separated individually here, and is impregnated with the treating liquid. Then, an excessive treating liquid is removed by squeezing rolls. The base material is dried, while passing through a drying chamber.
