40Cr Cylindrical Gear Helical Tooth For 6B Twin-Needle Machine
Appearance Shape
Tooth profile: The contact line of the tooth flank is an oblique line, and this helical tooth design allows for a smoother gear mesh.
Overall shape: Both the big gear and the pinion are cylindrical, with a round hole in the middle for mounting on the shaft. The diameter of the large gear is significantly larger than that of the small gear, and the thickness is relatively thicker, and there are evenly distributed helical teeth.
Structural Parameters
Helix angle: The helix angle is suitable for the 6B double-needle machine between 8° and 25° to ensure smooth transmission and moderate axial force.
Modulus: Based on the transmission requirements of 6B two-needle machine, the module is made in the common range of 1.5 - 4 to meet the power transmission and speed matching.
Number of teeth: According to the design of the transmission ratio of the double-needle machine, the number of teeth of the large gear is more than that of the pinion to ensure the coordinated operation.
Material Properties
High strength: Considering that the gear needs to bear a large force when the 6B double-needle machine is working, the gear is made of high-quality alloy steel, and after heat treatment, the surface is hard and tough, which can resist impact and heavy load.
Good wear resistance: After finishing, the surface of the gear is smooth, which reduces the coefficient of friction, reduces wear and extends the service life in long-term operation.
Transmission Performance
Smooth transmission: When the 6B double-needle machine is running, the gradual meshing of the helical teeth makes the power transmission smooth, reduces vibration and noise, and ensures the stable sewing work.
Strong bearing capacity: Multiple gear teeth participate in the meshing at the same time during operation, and the large and small gears can be matched to share the load and meet the power needs of the double-needle machine under different sewing conditions.
