Stainless Steel Archimedes Double Head Worm Transmission Reducer Parts

Stainless Steel Archimedes Double Head Worm Transmission reducer parts.

Description

Transmission parts include gears, axles, crankshafts, shafts, connecting rods, belts and chains, pulleys, etc.

Worm refers to a gear with one or several helical teeth and meshing with the worm gear to form a staggered shaft gear pair. The indexing surface can be a cylindrical surface, a conical surface or a torus surface.

Archimedes worm (ZA worm) This worm, on the plane perpendicular to the worm axis (ie the end face), has an Archimedes spiral (Fig. 1), and the tooth profile on the plane containing the axis ( That is, the axial tooth profile) is a straight line, and its tooth profile angle α0=20°. It can be turned on a lathe with a single tool (when the lead angle γ≤3°) or a double tool (when γ>3°) with a straight edge.

When choosing the number of worm heads z1, the three aspects of transmission ratio, efficiency and manufacturing are mainly considered. From the manufacturing aspect, the more heads, the higher the requirement of worm manufacturing accuracy. From the perspective of improving efficiency, the more heads, the higher the efficiency; if required For self-locking, a single head should be selected. From the aspect of improving the transmission ratio, a small number of heads should be selected; in the power transmission, under the premise of considering the compact structure, it should be well considered to improve the efficiency. When the i transmission is relatively small, a multi-head worm should be used.
