Embodiment

[0032] Please refer to Figure 1-5 According to the lifting mechanism of the harmonic reducer implemented in the present invention, it includes two groups of rotating parts 2, the first supporting arm 4 and the second supporting arm 5 connected by the rotating parts 2, and the first supporting arm 4 and the first supporting arm 4 A fixed base 3 connected by a rotating part 2.

[0033] The rotating part 2 is mainly composed of a motor, a harmonic reducer, and an output flange type flexible spline fixing seat. Among them, the harmonic reducer is a reduction mechanism composed of a rigid spline, a flexible spline, a flexible bearing, and a wave generator that causes radial deformation of the flexspline. The motor directly drives the harmonic reducer, and the harmonic reducer drives the flexible spline fixed seat to rotate, and the fixed bracket is rigidly connected to the steel wheel and fixed so that it generates torque with the flexible spline fixed seat, driving the support a...

Abstract

The invention provides a lifting mechanism carrying a harmonic reducer and a holder. Two supporting arms are rotatably connected through a rotating part, and the supporting arm located at the bottom is connected with a base through the other rotating part; the rotating component comprises a harmonic reducer, a servo motor, a fixing support and an output flange type flexible gear fixing base. The fixing support and the output flange type flexible gear fixing base are matched with each other and can move relatively. The servo motor is arranged to directly drive the wave generator to drive the flexible gear fixing base to rotate, and the fixing support is rigidly connected with the bottom end of the supporting arm so as to drive the supporting arm to rotate. The device is small in size, light in weight, stable in movement, large in bearing capacity and high in transmission precision, a harmonic transmission scheme of a precise lifting mechanism can be realized on the basis of not changing the functions of a traditional lifting mechanism, and the transmission precision and the reduction ratio of the lifting mechanism are improved. And the method can be suitable for occasions with relatively high space requirements and relatively harsh precision requirements.

Description

technical field [0001] The invention belongs to the technical field of monitoring pan-tilt transmission, and in particular relates to a lifting mechanism equipped with a harmonic drive reducer and a pan-tilt adopting the lifting mechanism. The invention belongs to the technical field of lifting transmission, and in particular relates to a lifting mechanism equipped with a harmonic drive reducer. It mainly includes servo motor, harmonic reducer, circuit board, support arm and fixed base. Background technique [0002] Traditional gimbals generally only have two degrees of freedom to achieve horizontal and pitch movements. For occasions that require large-scale tracking, the pan-tilt camera is required to be able to achieve lifting operations. At present, there is no special standard part for the lifting operation of the cloud platform, and technicians generally use a gear meshing method or a wire rope lifting method to move vertically or obliquely to realize the lifting of t...
