Abstract
The invention provides an aviation steel cable tension accurate measurement device, and relates to the technical field of tension measurement equipment. The aviation steel cable tension accurate measurement device comprises a pulley (5), an upper cushion block (6), a lower cushion block (7), a force measuring steel cable (8), a connecting plate (10), a measured steel cable (11) and a bottom plate (14), a side groove (15) is formed in the upper cushion block (6), a plurality of T-shaped grooves (13) are formed in the lower cushion block (7), the circle centers of the side groove (15) and the T-shaped grooves (13) coincide, and a through hole is formed in the circle center; one end of the connecting plate (10) is fixed on the bottom plate (14), and the other end of the connecting plate (10) is provided with a T-shaped piece (12); the number of the pulleys (5) is four, the pulleys (5) are arranged in a rectangular shape, the center of the rectangle is provided with a red dot fixed on the bottom plate (14), one end of the force measuring steel cable (8) is connected with the sensor (2), and the other end of the force measuring steel cable (8) is connected with the lead screw (9). The technical problem that the steel cable tension measurement accuracy is insufficient is solved.
Description
technical field [0001] The invention relates to the technical field of tension measuring equipment, in particular to an accurate tension measuring device for aviation steel cables. Background technique [0002] Cable transmission is widely used in aircraft, among which the aircraft control system uses more cable transmission, generally aileron control, elevator control, rudder control, rudder surface lock control, rudder surface trim control, throttle control, etc., in use When cable transmission, generally pay attention to the following four points: First, the steel cable must meet the pre-tightening force requirements after assembly. If the steel cable pre-tightening force is insufficient and the steel cable is loose, it will slide relative to the pulley, affecting The accuracy of the operation is also easy to cause the wear of the pulley; if the pre-tightening force is too large, the steel cable will bear an excessive load, and the friction force between the steel cable a...
