The invention relates mainly to an assembly comprising:a combustion engine ring gear having a plurality of teeth, the said ring gear being defined by a modulus and a pressure angle,a starter comprising a pinion (31) able to engage with the said ring gear of the said combustion engine, the said pinion (31) having a plurality of teeth (42) is defined by a modulus (Mp) and a pressure angle (alpha_p), characterized in that a pinion product which is the product of the modulus (Mp) of the said pinion (31) and the cosine of the pressure angle (alpha_p) of the said pinion (31) is greater than a ring-gear product equal to the product of the modulus of the said ring gear and the cosine of the pressure angle of the said ring gear.

The present application discloses an overload impact-resistant planetary reducer, including a tooth face portion made of a rigid material and a buffer portion capable of being elastically deformed. The buffer portion is made of a material having certain rigidity and capable of being elastically deformed under an impact force, and is coaxially nested with the tooth face portion to form a reducer component capable of preventing overload impact. The planetary reducer is capable of being elastically deformed under the impact force, effectively absorbing energy during overload impact, thus protecting transmission parts such as gears. The structure is simple and practical. The present application further discloses an overload impact-resistant planetary reducer, a robot joint and a quadruped robot.
