Abstract

Provided is a speed reduction device with which it is possible to reduce the inertial moment of an internal mechanism, and inhibit, when an output member and a driven member are linked, the output member or the driven member from becoming damaged. This speed reduction device (1) has a first member (27) and a speed reduction mechanism that includes internally toothed gears (22g, 23g) and an externally toothed gear (12) that engages with the internally toothed gears, the speed reduction device (1) transmitting rotary motion to a driven member (62), the rotary motion having been reduced in speedby the speed reduction mechanism, wherein the speed reduction device (1) has a protection member (28) disposed between the first member and the driven member. The first member (27) is made from a material having a lower specific gravity than that of the internally toothed gears and / or the externally toothed gear and a lower hardness than that of the driven member, and the protective member (28) ismade from a material having a higher hardness than that of the first member.

Description

technical field

[0001] The invention relates to a reduction gear. Background technique

[0002] Conventionally, there is a deceleration device that decelerates a rotational motion and outputs the decelerated rotational motion to a driven member. A component that is connected to a driven component and outputs rotational motion is called an output component. Generally, each member constituting the reduction gear including the output member is made of high-strength members such as steel.

[0003] Patent Document 1 discloses a reduction gear transmission including a lightweight bearing and a lightweight internal gear. In the bearing of Patent Document 1, the main body member is made of aluminum alloy or the like, and the rolling surface forming member is made of iron-based material. In the internal gear of Patent Document 1, the main body member is made of aluminum alloy or the like, and the tooth portion forming member is made of iron-based material.
