Worm gears and worm wheels must have the same handedness when meshing; only with the same handedness can they engage and make contact. Definition of Worm Gears and Worm Wheels: The worm gear and worm wheel structure is commonly used to transmit motion and power between intersecting shafts. The worm wheel and worm gear in their intermediate plane are equivalent to a gear and rack, with the worm gear resembling the shape of a screw. Worm gears and worm wheels are divided into the following series: WH series worm gear reducers: WHT/WHX/WHS/WHC. CW series worm gear reducers: CWU/CWS/CWO. WP series worm gear reducers: WPA/WPS/WPW/WPE/WPZ/WPD. TP series enveloping worm gear reducers: TPU/TPS/TPA/TPG. PW type plane double-enveloping toroidal worm gear reducers. Based on the shape of the worm gear, worm gear transmissions can be classified into cylindrical worm gear transmissions, toroidal worm gear transmissions, and conical worm gear transmissions.
