A swash plate spring device capable of attenuating high-frequency vibration of swash plate and measuring swash plate angle

Abstract

The invention discloses a tilting tray spring device capable of attenuating high-frequency vibration of a tilting tray and measuring the angle of the tilting tray. The center of one end face of a fixed spring seat and the center of one end face of a movable spring seat are each provided with a boss. A center hole is formed in the face of the boss of the fixed spring seat. The boss of the movable spring seat is coaxially connected in the center hole of the boss of the fixed spring seat in a sleeved manner. A spring is arranged on the outer portion of the portion formed after the two bosses are in sleeve connection. A center through hole is formed in the center of the other end face of the fixed spring seat. A displacement sensor probe is mounted in the center through hole. The other end of the movable spring seat is connected with the tilting tray. According to the tilting tray spring device, the problem of high-frequency vibration of the tilting tray and the problem that a traditional tilting tray angle measuring mechanism is too complex are solved, a tilting tray vibration attenuation mechanism and a tilting tray angle measuring mechanism are integrated, and therefore high-frequency vibration of the tilting tray can be efficiently attenuated, and the angle of the tilting tray can be measured in real time; and the mechanisms are simple and reliable, and the angle measuring precision is high.

Description

technical field [0001] The invention relates to a swash plate spring device of a plunger pump, in particular to a swash plate spring device capable of attenuating high-frequency vibration of the swash plate and measuring the angle of the swash plate, belonging to the technical field of fluid transmission and control. Background technique [0002] As a key component in the hydraulic system, the plunger pump provides the power source for the hydraulic system. The vibration of the swash plate in the plunger pump will cause the pulsation of the high-pressure oil discharged by the pump to intensify, and will cause the vibration of the mechanical structure of the pump to intensify, affecting the performance and life of the hydraulic system and the pump itself. Therefore, it is necessary to take measures to suppress the vibration of the swash plate. The vibration angle of the swash plate directly determines the displacement of the plunger pump, and is closely related to the struct...
