摘要： Composite worm gears having little residual stress are prepared by forming a tube (101) of synthetic resin by extrusion, compression molding, or centrifugal processing, and fixing the tube thus produced or rings (102) cut therefrom onto a boss (103) or core (105), preferably of metal. The process allows high performance high molecular weight thermoplastics to be employed.
