Embodiment 1
[0020] see figure 1 : A single-cut double arc gear, the gear 4 has a plurality of teeth 5, and each tooth 5 has two side surfaces, an addendum part and a dedendum part. Among them, the addendum part is formed by the addendum trace 1, and the addendum trace 1 is a straight line; the dedendum part is formed by the combination of the arc-shaped transition trace 8 and the dedendum trace 2, and the radius of the transition trace 8 is 0.5m (m represents the modulus, the same below), taking m=2 mm (the same below), then the radius of the transition trace 8 is 1 mm, and the dedendum trace 2 is a straight line; and on the same side there is another An arc-shaped convex trace 6 and an arc-shaped concave trace 7, the radius of the convex trace 6 is equal to the radius of the concave trace 7, and the radii of the convex trace 6 and the concave trace 7 are 1m respectively, then the convex trace The radii of the lines 6 and the concave traces 7 are 2 mm, respectively. One end of the conve...
Embodiment 2
[0022] see figure 1 : A single-cut double arc gear, the gear 4 has a plurality of teeth 5, and each tooth 5 has two side surfaces, an addendum part and a dedendum part. Among them, the addendum part is formed by the addendum trace 1, and the addendum trace 1 is a straight line; the dedendum part is formed by the combination of the arc-shaped transition trace 8 and the dedendum trace 2, and the radius of the transition trace 8 is 0.4m, take m=2 mm (the same below), then the radius of the transition trace 8 is 0.8 mm, and the dedendum trace 2 is a straight line; on the same side there is an arc-shaped convex trace 6 and a The arc-shaped concave trace 7, the radius of the convex trace 6 and the radius of the concave trace 7 are equal, and the radii of the convex trace 6 and the concave trace 7 are respectively 2m, then the radius of the convex trace 6 and the concave trace 7 4mm respectively. One end of the convex trace 6 is in contact with the addendum trace 1 of the addendum ...
Embodiment 3
[0024] see figure 1 : A single-cut double arc gear, the gear 4 has a plurality of teeth 5, and each tooth 5 has two side surfaces, an addendum part and a dedendum part. Among them, the addendum part is formed by the addendum trace 1, and the addendum trace 1 is a straight line; the dedendum part is formed by the combination of the arc-shaped transition trace 8 and the dedendum trace 2, and the radius of the transition trace 8 is 0.3m, take m=2 mm (the same below), then the radius of the transition trace 8 is 0.6 mm, and the dedendum trace 2 is a straight line; on the same side there is an arc-shaped convex trace 6 and a The arc-shaped concave trace 7, the radius of the convex trace 6 and the radius of the concave trace 7 are equal, the radius of the convex trace 6 and the concave trace 7 is 3m respectively, then the radius of the convex trace 6 and the concave trace 7 6mm respectively. One end of the convex trace 6 is in contact with the addendum trace 1 of the addendum part...
