Abstract

The invention provides a gear device which can more easily realize packaging amount reduction of lubricant. The gear device (G1) is provided with a housing (10) and a speed reducing mechanism (20) which is accommodated in the housing, wherein the speed reducing mechanism is provided with an input-grade parallel shaft gear set (30), an output-grade parallel shaft gear set (40), and an intermediate-grade parallel shaft gear set (50) which is arranged between the input-grade parallel shaft gear set and the output-grade parallel shaft gear set. The housing is provided with a first accommodating chamber (61) for accommodating the input-grade parallel shaft gear set, and a second accommodating chamber (62) for accommodating the intermediate-grade parallel shaft gear set and the output-grade parallel shaft gear set.

Description

[0001] This application claims priority based on Japanese Patent Application No. 2015-221676 filed on November 11, 2015. The entire contents of this Japanese application are incorporated herein by reference. technical field [0002] The invention relates to a gear device. Background technique [0003] Patent Document 1 discloses a gear device including a case and a reduction mechanism housed in the case. [0004] The speed reduction mechanism of the gear device includes an input stage parallel shaft gear set, an output stage parallel shaft gear set, and an intermediate stage parallel shaft gear set disposed between the input stage and the output stage. [0005] The casing is provided with a partition wall, and a parallel shaft gear set of an output stage that requires high support strength is arranged in a separate chamber (second storage chamber) formed by partitioning the partition wall.
