211WF1-014 Finished Hook Shaft Pinion and 211WF1-005 Finished Lower Shaft Main Gear

This series of 211WF1-014 Finished Hook Shaft Pinion and 211WF1-005 Finished Lower Shaft Main Gear are dedicated helical gear transmission components for sewing equipment. Made of high-quality 20Cr carbon structural steel and manufactured through multiple precision processes, they are suitable for the high-frequency transmission requirements of sewing machinery and ensure stable equipment operation.

The 211WF1-014 Finished Hook Shaft Pinion features a pressure angle of 20°, a module of 1, 14 teeth, a speed ratio of 2, and a helix angle of 45°/L. It has an inner diameter of φ10mm, an outer tooth diameter of 21.85mm, an overall length of 28.5mm, and a single-piece weight of 0.0409kg. Its production process includes normalizing, turning, threaded hole machining, reaming, hobbing, heat treatment, shot blasting, and screw assembly. With high tooth surface strength and excellent wear resistance, it serves as a core component of the hook drive system.The 211WF1-005 Finished Lower Shaft Main Gear comes with a pressure angle of 20°, a module of 1, 28 teeth, and a helix angle of 45°/L. It has an inner diameter of φ9.5mm, an outer tooth diameter of 41.65mm, an overall length of 32mm, and a single-piece weight of 0.1761kg. Formed by processes like normalizing, turning, CNC machining center processing, reaming, hobbing, heat treatment, and shot blasting, it meshes precisely with the pinion to realize stable and noiseless transmission, making it ideal for power transmission scenarios of the lower shaft in sewing equipment.Both gears have strong structural adaptability, which can meet the continuous operation conditions of sewing machinery and effectively improve the transmission efficiency of the equipment.
