Problems solved by technology

As a result of this, metal molds are prone to deterioration, resulting in reduced productivity
[0008] Therefore, for the integrally formed gear disclosed in Patent Document 1, it is necessary to improve the problems of low strength of the small-diameter gear and low productivity due to low strength near the right-angled corner and low packing density in the middle of the small-diameter gear.

Abstract

The invention provides an integrally molded gear capable of inhibiting drop of strength of a pinion. A comparison example is indicated in figure 7(a). A hardened part (105) indicated by hatching can be provided by applying induction hardening on a pinion (104). Hardening depth at a perpendicular corner part (102), however, is very small. A vicinity of the perpendicular corner parts (102) becomes a fragile part when load acts on the pinion (104). Figure (b) indicates an embodiment. A hardened part (75) indicated by hatching can be provided by applying induction hardening on a pinion (53). Sufficient hardening depth can be secured although hardening depth at an inclined surface (57) is a little bit small. Consequently, strength of the pinion (53) is increased. Since a conventional perpendicular corner part is changed to the inclined surface, strength after hardening is averaged and strength of the pinion can be increased.

Description

technical field [0001] The invention relates to an integrally formed gear suitable for a kick starter of an internal combustion engine. Background technique [0002] An integrally formed gear with a small-diameter gear on the hub of a large-diameter gear. Although it is a special gear, it has the advantage that two gears can be arranged in a small space, and can be built into various rotary machines or rotary devices. middle. [0003] In Patent Document 1 (Japanese Unexamined Patent Publication No. 2004-138055, figure 1 ) discloses a technique of building an integrally formed gear into an internal combustion engine. [0004] In Patent Document 1 figure 1 In the figure, reference numeral 11 indicates a main driven gear, and reference numeral 21 indicates a starter driven gear, and both gears 11 and 21 form an integrally formed gear part. [0005] The tooth bottom surface of the starting driven gear 21 with a small diameter extends along the left-right direction in the fig...
