Abstract

A robot and an assembly method thereof are provided. A robot (100) comprises: a first arm link (101) comprising a joint housing(1011) and an internal engaging member (1012) arranged on an inner surface of the joint housing (1011); a second arm link (102) comprising an output flange (1021); and a moving assembly (104) at least partially arranged in the joint housing (1011). The moving assembly (104) comprises: an input shaft (1041) adapted to rotate about an axis (X) of the input shaft (1041); and at least one intermediate member (1042) coupled to the output flange (1021) and adapted to be driven by the input shaft (1041) to rotate while engaging with the internal engaging member (1012), to cause a relative movement between the first and second arm links (101, 102). By integrating the relative static parts of the gearbox, high connection strength of connections between the robot arm links can be achieved in a more cost-efficient and space-saving manner.

Description

technical field [0001] Embodiments of the present disclosure generally relate to a robot and an assembly method thereof. Background technique [0002] A gearbox is a device that uses gears and gear trains to provide speed and torque conversion from a rotating power source to another device. Conventional planetary gearboxes typically include one or more external gears (ie, planet gears) that rotate around a central gear (ie, sun gear). Typically, the planet gears are mounted on a movable arm or carrier, which itself can rotate relative to the sun gear. Planetary gearboxes also include the use of an outer ring gear or annulus that meshes with the planet gears. Planetary gears are generally classified as simple planetary gears or compound planetary gears. A simple planetary gear has a sun gear, a ring gear, a carrier, and a planetary gear set. [0003] Usually, as a precision component manufactured by an external supplier with different materials and processing techniques, ...
