摘要： A method of machining the gear teeth (2) of a worm wheel (1) by engaging a worm (unshown) to which a polishing or grinding material is added with the gear teeth (2) of the worm wheel (1) with at least the gear teeth formed of a synthetic resin and rotating the worm. As shown in Fig. 5, an angle formed by the axis of the worm wheel and a virtual helical axis formed when the gear teeth of the worm wheel are formed is approximately aligned with an angle formed by the axis of the worm wheel and the helical axis of the worm for machining.

摘要： An object of the present invention is to provide a grease composition for resin lubrication which is capable of keeping good the sliding lubrication between a resin member and a-metal member, and between a metal member and another metal member over the long term. The present invention provides a grease composition for resin composition which is characterized by including a base, a thickener, and at least one of a nonpolar wax and a polar wax. Further, the grease composition for resin lubrication is applied to a telescopic shaft for vehicle steering or an electric power steering apparatus, thereby to improve the durability, and to achieve a longer life.
