Title:
DOG CLUTCH
Document Type and Number:
Japanese Patent JP2018071633
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a dog clutch which can elongate a period in which dog teeth can be engaged without lowering the durability of the dog teeth.SOLUTION: Lengths of outward protrusions 70a in a peripheral direction are formed shorter than lengths of crests 40a at which the outward protrusions 70a of gear-side dog teeth 38e are formed, and thereby intervals β of the outward protrusions 70a in the peripheral direction become longer than lengths α of troughs 42a of the gear-side dog teeth 38a. Here, a period in which inward protrusions 88a can be interposed between the adjacent outward protrusions 70a in the peripheral direction becomes a period in which the gear-side dog teeth 38a and dog teeth 78a can be substantially engaged with each other, and as a result, the period in which the gear-side dog teeth 38a and the dog teeth 78a can be engaged with each other can be elongated more than before.SELECTED DRAWING: Figure 9
