The figure is a perspective view of the dog clutch in a state where the driven rotary disk is pressed into contact with the drive rotary disk which is not in a meshing position relationship, FIG. FIG. 4 is a front view showing the main parts of the dog clutch, showing the state immediately after the dog clutch becomes parallel to the dog clutch in the process of transitioning from the state shown in FIG. 2 to the state shown in FIG. It is a diagram. DESCRIPTION OF SYMBOLS 1... Drive rotary disk, 6... Driven rotary disk, 8... Spring, 9... Meshing convex part, 9a... Chamfered part,

Claims

[Scope of utility model registration request]

(1) A driving rotary disk and a driven rotary disk, which mesh with each other to enable power transmission, face each other with their rotation axes aligned, and a spring causes one of the two rotary disks to move to the other. In a dog clutch that is biased toward the tooth, one of the rotary discs is provided with a meshing convex portion formed from the inside to the outside, and the other is provided with a meshing concave portion that engages with the meshing convex portion, and An annular protrusion is formed around and inside the rotating shaft, and is partially cut out at the position of the engaging recess, and when both rotary disks are not in an interlocking position relationship, the engaging protrusion and the annular protrusion are provided. A dog clutch characterized in that it can come into contact only at the ends.

(2) Guide the meshing projection from the state in which it is in contact with the annular projection to the state in which it engages with the meshing recess (a chamfered portion is formed on the meshing projection and the annular projection; The dog clutch according to claim 1, wherein the amount of protrusion is greater than the sum of the amounts of chamfering of both the convex portions.

(3) A utility model registered in claim 1 or 2, characterized in that the contact surfaces of the meshing convex portion and the annular convex portion that abut against each other are treated to reduce the coefficient of friction. Dog clutch as described.
