Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings.

[0028] A high damping moment density hysteresis damper is composed of a stator assembly 1 and a rotor assembly 2, the rotor assembly 2 penetrates the stator assembly 1, and there is a working gap between the two end faces of the hysteresis disk of the rotor assembly 2 and the end face of the stator assembly 1; A damping torque is generated when the rotor assembly 2 and the stator assembly 1 have relative rotational motion. Such as figure 1 , Figure 9 shown.

[0029] Such as figure 2 As shown, the stator assembly 1 is composed of a housing assembly 7 and a right end cover assembly 3; as image 3 As shown, the housing assembly 7 is composed of a left end cover assembly 9 and a housing 11, and the two are fixedly connected; as Figure 4 , the left end cap assembly 9 is made up of a left end cap 12 and a permanent magnet 13, and the contact surfaces of the two are b...

Abstract

The invention discloses a hysteresis damper with high damping torque density, and belongs to the technical field of aviation automatic control. The defect that the damping torque stability of a contact type damper is not ideal is overcome. The high-damping torque density hysteresis damper is composed of a stator assembly and a rotor assembly, the stator assembly fixes a left end cover assembly anda right end cover assembly in a shell through screws, the rotor assembly penetrates into the stator assembly through a left bearing and a right bearing of a shaft, and damping torque is generated when the rotor assembly and the stator assembly rotate relatively. Structural connection and torque transmission functions are provided for electromechanical products such as an automatic accelerator actuating mechanism, an electric steering engine and an accelerator console, the stability of the damping device can be greatly improved, the service life of the damping device can be greatly prolonged,and the damping torque density is higher than that of similar products at home and abroad.

Description

technical field [0001] The invention belongs to the technical field of aviation automatic control, and relates to a hysteresis damper with high damping moment density. Background technique [0002] The present invention aims at the unsatisfactory damping torque stability of the contact force sensing device used in the current airborne device due to environmental climate change and mechanical stress change; The occurrence of uncertain factors such as hysteresis may cause the gradual decline or even sudden change of the control force transmitted to the pilot, which will affect the smoothness and maneuverability of the pilot's control of the aircraft in the slightest, and will endanger the flight safety and the life of the pilot in severe cases. The hysteresis damper with high damping moment density of the present invention belongs to the non-contact structure, is less affected by environmental changes, does not have contact friction, and has higher stability and service life t...
