Abstract: The present invention provides a manufacturing method for a toothed power transmission member having an oil reservoir, whose ability to hold a lubricating agent is enhanced, suitable for mass production without increasing a manufacturing cost so much, and also provides a toothed power transmission member manufactured by this manufacturing method.
A method of manufacturing a toothed power transmission member having an oil reservoir according to the present invention includes steps of forming primitive concave portion 21, which form a basis for the oil reservoir, on a surface of a toothed power transmission member work, and forming a tooth surface by processing the toothed power transmission member work such that a trace of the primitive concave portion is left on the toothed power transmission member thereby to form a toothed power transmission member. The trace of the primitive concave portion 21, which is formed in the step of forming a tooth surface and left on the toothed power transmission member, serves as the oil reservoir.

Abstract: A method of producing a toothed transmission member having oil holders, not causing very large increase in production costs, suitable for mass production, and having increased lubricant retaining ability, and a toothed transmission member produced by the method. The method of producing a toothed transmission member with oil holders has a primitive recess forming process for forming primitive recesses (21), the origin of the oil holders, in the surface of a material for the toothed transmission member and has a tooth surface forming process for forming a toothed transmission member by processing the toothed transmission member so as to leave marks of the primitive recesses. The marks of the primitive recesses (21) left in the toothed transmission member formed by the tooth surface forming process function as the oil holders.
