Abstract

The invention discloses a continuously adjustable type damper. The continuously adjustable type damper comprises a shell, an inner piston, an outer piston, a motor assembly, a motor screw, a T-shapedinstallation seat, a through cover outer sealing ring, a through cover, a through cover inner sealing ring and a through cover bolt. According to the continuously adjustable type damper, the inner piston and the outer piston are matched with each other, the airtightness and the self-adjustability of cooperation of a circular cone and a cone hole are utilized, rotating movement is changed to be rectilinear movement through gear reduction and a spiral structure, fine adjustment of the damping coefficient is achieved based on the simple structure, and real-time and continuous adjustment can be achieved. According to the continuously adjustable type damper, under the tendency of the higher and higher requirements for vibration isolation, vibration reduction and automation control, the structure is simple, the damping coefficient can be continuously adjusted in real time, the market requirements can be met, and obvious economic benefits are brought.

Description

technical field [0001] The invention belongs to the technical field of dampers, and relates to a continuously adjustable damper, in particular to a damper capable of continuously adjusting the damping coefficient by controlling a motor. Background technique [0002] Due to its nature, the damper with adjustable damping can be used in many occasions with special requirements. After systematic searching of CNKI, Shanghai Intellectual Property Office database, US patent database and European patent database, the following 1 literature and 3 related patents. [0003] Among them, "Parametric Analysis of Conical Liquid Damper Based on ANSYS" analyzes a conical liquid damper. The conical damper in this paper is a rotary damper. The main functions of the cone and the conical hole are centering and positioning, control and What adjusts the rotary torque of the cone damper is the structure of double helical oil guide grooves on the cone surface. A continuously adjustable damper of t...
