• High-Precision Transmission Helical GearFeatures: good meshing, excessive precision, strong bearing capacity; corrosion resistance.Helix angle: 22.5 degrees20 teeth specification:Diameter: 11.82mmHole diameter: 3/4/5mmTooth thickness: 6mmBoss thickness: 5mmOverall thickness: 11mmScrew: M3Boss diameter: 9-10mm (5mm gap is 10mm)40/50/60/80 tooth specification:Center distance parameters: (In order to attain nice use accuracy, it's endorsed to reserve 0.02-0.04mm for the center distance and aspect clearance)1:2 (20 teeth + 40 teeth) ------------------------>16.25mm1:2.5 (20 teeth + 50 teeth)------------>18.95mm1:3 (20 enamel + 60 teeth)------------->21.65mm1:4 (20 enamel + 80 teeth)---------------------------->27.06mmCharacteristics of helical gears:*The meshing characteristics of helical gears are larger than that of straight gears, the diploma of coincidence is large, and the transmission is smoother.*The force of the meshing between the teeth is from small to large, and then from broad to small, the nice touch field is larger, so the meshing between the tooth has no impact, and the noise would be greater suppressed. Compared with spur gears of a similar specification, it has higher transfer speed.*As a high-precision transmission, helical gears have incomparable advantages over spur gears. Therefore, the application of helical gears in high-precision reducers is extra common.
