The invention provides an integrated joint with strain gauge torque feedback. The integrated joint comprises a fixed support and a motor arranged on the fixed support. The motor is provided with a power output end; an annular shell is arranged on the outer side of the motor; a torque output structure is arranged at the far end of the shell and supported on the outer side of the motor through a four-point contact bearing, the near end of the shell is fixedly connected with the power output end, the two ends of the shell are supported through an auxiliary bearing, and the part, between the four-point contact bearing and the auxiliary bearing, of the shell has the length and is of a thin-wall structure. A plurality of strain gauges are pasted on the outer wall of the peripheral side of the thin-wall structure and used for measuring the torque borne by the thin-wall structure.
本发明提供一种带应变片扭矩反馈的一体化关节,所述一体化关节包括固定支架以及布置在固定支架上的电机,所述电机具有动力输出端,在电机的外侧设有一个环形的壳体,所述壳体的远端设有扭矩输出结构并通过四点接触轴承支撑在电机外侧,近端与所述动力输出端固定连接,所述壳体的两端之间又通过辅助轴承支撑,其中,所述壳体在四点接触轴承与辅助轴承之间的部分具有长度而且为薄壁结构;在薄壁结构的周侧外壁上粘贴有数个应变片,所述应变片用于测量薄壁结构所承受的扭矩。
