Beam electric drive transmission sensing deceleration system

The utility model discloses a cross beam electric drive transmission sensing speed reduction system which is characterized in that outer splines distributed in the circumferential direction are arranged on the outer circumferential face of an auxiliary shaft, a speed reduction first-stage driven gear is provided with a mounting sleeve matched with the auxiliary shaft, and inner splines matched with the outer splines are distributed on the inner wall of the mounting sleeve in the circumferential direction; strain gauge mounting gaps are reserved between the adjacent external splines and internal splines, and strain gauges are arranged in the strain gauge mounting gaps. By the adoption of the technical scheme, the high-precision and large-load cross beam electric drive transmission sensing speed reduction system can be used for conducting accurate motion control on the Z axis, real-time detection of torque loads is achieved, accurate closed-loop control over loads input and output by a Z-axis lifting system is
