Beschreibung
Zusammenfassung:	The invention relates to the technical field of speed reducers, in particular to a speed reducer with an adjustable transmission ratio. The input shaft is arranged in the accommodating cavity; the planet wheel comprises a planet shaft and a planet bevel gear fixedly installed on the planet shaft, and the planet shaft is fixedly connected with the input shaft; the output shaft is arranged in the accommodating cavity; the transmission bevel gear is fixedly arranged on the output shaft and is meshed with the planetary bevel gear; the adjusting mechanism comprises a braking assembly and at least two transmission assemblies, each transmission assembly comprises an adjusting bevel gear meshed with the planetary bevel gear, and the tooth numbers of the adjusting bevel gears in different sets are different; the brake assembly brakes one adjusting bevel gear, so that the braked adjusting bevel gear, the planetary bevel gear and the transmission bevel gear form a planetary gear train, and therefore the transmission rat
