Description

142525003 Spiral Pinion

Product No. 142525003 spiral pinion is categorized as a spiral bevel gear, serving as a core transmission component dedicated to sewing machinery. This gear features a pressure angle of 20°, a module of 1.2, 20 teeth, and a spiral angle of 35° left-hand (35°/L), with a gear ratio of 2 when matched with its corresponding gear. In terms of structural dimensions, it has an inner diameter of 12mm, an outer tooth diameter of 25.85mm, an overall length of 19.87mm, and a unit weight of 0.037kg. Made of 20CrMo alloy steel, it undergoes a precision manufacturing process consisting of normalizing → turning → threaded hole machining → reaming → gear milling → heat treatment → shot blasting → reaming → screw assembly. Multiple production procedures ensure the gear’s dimensional accuracy and assembly compatibility, meeting the low-noise and high-stability operation requirements of the transmission system of sewing machinery.

142525004 Spiral Gear

Product No. 142525004 spiral gear belongs to the spiral bevel gear category, acting as the matching transmission component of 142525003 spiral pinion for sewing machinery. It has a pressure angle of 20°, a module of 1.2, 44 teeth, and a spiral angle of 35° right-hand (35°/R). Regarding structural dimensions, it has an inner diameter of 15mm, an outer tooth diameter of 52.3mm, an overall length of 18.28mm, and a unit weight of 0.1374kg. Made of the same 20CrMo alloy steel, it adopts the identical precision manufacturing process as the pinion: normalizing → turning → threaded hole machining → reaming → gear milling → heat treatment → shot blasting → reaming → screw assembly. Cooperating with the matching pinion, it achieves stable power transmission and serves as a key component of the transmission system of sewing equipment.
