Speed reducer, drive device, and construction machine
A speed reducer (10) according to an embodiment is provided with a first speed reduction unit (100) and a second speed reduction unit (200). The first speed reduction unit (100) is provided with: a first carrier (101); a first housing (102) that surrounds the first carrier (101) and is held by the first carrier (101) so as to be rotatable relative to the first carrier (101); and a first speed reduction unit (103) that includes a first center shaft (131) that corresponds to a first input unit that is held by the first carrier (101) and that inputs rotation from the drive shaft (303). The second speed reduction unit (200) is provided with: a second carrier (201); a second housing (202) that surrounds the second carrier (201) and is held by the second carrier (201) so as to be rotatable relative to the second carrier (201); and a second reduction unit (203) that includes a second center shaft (231) that corresponds to a second input unit that is held by the second carrier (201) and that inputs rotation together with the first center shaft (131) from the drive shaft (303).
一实施方式的减速器(10)具备第1减速单元(100)和第2减速单元(200)。第1减速单元(100)包括：第1齿轮架(101)；第1壳体(102)，其包围第1齿轮架(101)且以可相对于第1齿轮架(101)相对旋转的方式保持于第1齿轮架(101)；以及第1减速部(103)，其包括与保持于第1齿轮架(101)且从驱动轴(303)输入旋转的第1输入部相对应的第1中心轴(131)。第2减速单元(200)包括：第2齿轮架(201)；第2壳体(202)，其包围第2齿轮架(201)且以可相对于第2齿轮架(201)相对旋转的方式保持于第2齿轮架(201)；以及第2减速部(203)，其包括与保持于第2齿轮架(201)且与第1中心轴(131)一起从驱动轴(303)输入旋转的第2输入部相对应的第2中心轴(231)。
