Suitable for transmission of sewing equipment, with precise transmission, stability and durability.
Description
The 32721 series products are spiral bevel gears specially developed and designed for sewing equipment, including two core models: 32721.150020 and 32721.150010. Both are made of high-quality 20CrMo alloy structural steel, featuring excellent strength, toughness and wear resistance, which can fully meet the requirements of high-frequency transmission and low noise for sewing gears.
Among them, the 32721.150020 bevel gear has a pressure angle of 17°30′, a module of 1.05, 18 teeth, a speed ratio of 2, and a helix angle of 40° (right-hand rotation, marked as 40°/R); the key dimensional parameters are as follows: inner diameter 8mm, tooth outer diameter 21mm, total length 8.4mm, and the net weight of the product is only 0.0118kg, which is lightweight and precise in transmission. This product adopts a refined full-process manufacturing process, sequentially going through normalizing, turning, gear milling, heat treatment, shot blasting and reaming processes, and finally ensuring quality through full appearance inspection. Each process strictly controls precision to ensure smooth gear meshing and high transmission efficiency.
The 32721.150010 bevel gear has exactly the same material and process as the former, with a differentiated adaptive design in core specifications: the pressure angle is also 17°30′, the module is 1.05, the number of teeth is 36 (twice that of 32721.150020), and the helix angle is 40° (left-hand rotation, marked as 40°/L); in terms of dimensions, the inner diameter is 15mm, the tooth outer diameter is 38.33mm, the total length is 9.36mm, and the net weight is 0.0428kg. It also undergoes full-process precision processing such as normalizing, turning, gear milling and full appearance inspection, and is used in conjunction with the 32721.150020 bevel gear. Through the structural cooperation of left-hand and right-hand rotation and the tooth number ratio, it realizes the stable transmission requirement of sewing equipment.
