Abstract

The invention provides a driving device and a manufacturing method of the driving device. According to one embodiment of the present invention, a drive device is provided with: a plurality of gear motors each having a motor main body and a pinion gear that rotates about a central axis by means of the motor main body; and a main gear engaged with the plurality of pinion gears. The output of the main gear is 65% or more relative to the sum of the outputs of the plurality of gear motors.

Description

technical field [0001] The invention relates to a drive device and a method of manufacturing the drive device. Background technique [0002] In recent years, while electronic devices such as smartphones have become thinner, thinner gear motors are also required. Patent Document 1 discloses such a gear box device mounted in a thin electronic device. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2019-47589 [0004] In such a thin drive device, further higher output may be required. The present inventors conceived of reducing the thickness and increasing the output of the driving device by driving one main gear using a plurality of motors arranged in parallel. In such a configuration, there is a problem that it is difficult to output a high driving force due to a phase difference of the motor or the like. Contents of the invention [0005] One object of one aspect of the present invention is to provide a thin drive device capable of outputting high drive force...
