Embodiment Construction

[0020] Hereinafter, the spirit and essence of the present invention will be further elaborated in conjunction with the drawings and embodiments.

[0021] The external structure of the driving mechanism involved in the present invention is two sleeved cylinders with different diameters, the bottoms of the two cylinders are respectively connected to the upper flange and the lower flange; the two cylinders can be opposite around the central axis turn. The driving mechanism has a locking part and a driving part inside, and because the driving part is bulky and heavy, it is difficult to measure the driving torque.

[0022] combined reference Figure 1 to Figure 4 The driving torque testing device of the driving mechanism provided by the embodiment of the present invention includes: a guide rail plate 1, a parking frame 2, a pulley rod 3, a steel wire rope 4 and a weight box 5, the guide rail plate 1 is connected with the upper flange of the driving mechanism, and the The parking ...

Abstract

The invention discloses a driving torque testing device and method for a driving mechanism. The driving torque testing device for the driving mechanism includes a guide rail disk, a parking frame, a pulley rod, a wire rope and a weight box; the guide rail disk is connected with the upper flange of the driving mechanism; the parking rack is connected with the lower flange of the driving mechanism;the upper flange and the lower flange of the driving mechanism can rotate relative to each other; one end of the pulley rod is fixed to the parking frame; and one end of the wire rope is fixed to theguide rail disk and is wound around a groove at the outer arc surface of the guide rail disk; and the other end of the wire rope winds over a pulley and then is connected with the weight box.

Description

technical field [0001] The invention relates to the fields of driving mechanism locking and driving torque testing in the aerospace field, in particular to a driving torque testing device and method for a large-scale driving mechanism. Background technique [0002] A large-scale drive mechanism is a drive device for a large-area solar cell array, with a diameter of 2m and a weight of more than 300kg. It is the first large-scale drive product in the domestic aerospace field. This driving mechanism needs to measure the driving torque in the running test, and there is no effective measurement method at present. Contents of the invention [0003] The problem solved by the invention is that the prior art cannot test the driving torque of a large-scale driving mechanism in the aerospace field; in order to solve the problem, the invention provides a driving torque testing device and method for a driving mechanism. [0004] The driving torque testing device of the driving mechani...
