Active clearance compensation type cycloid pump/ motor device

Abstract

The invention discloses an active clearance compensation type cycloid pump / motor device. A cylinder side plate is provided with symmetrical openings; and each group of rotors consists of separated secondary rotors, an actuated piston and a corresponding piston chamber are arranged between the secondary rotors, the center of the rotors is provided with an inner gear, the tips of the rotors are provided with a sealing sheet, the sealing sheet is provided with a groove, the working face of the rotors is provided with a pressure passage, the pressure passage is communicated with the bottom of the groove of the sealing sheet, and the sealing face of the rotors is provided with a timing groove. The separated secondary rotors are designed to reflect the pressure of the working face or the pre-pressure of an elastic substance so as to automatically adjust the tightness of the sealing face of the rotors and the cylinder side plate and fulfill the purposes of low compression, low friction, high compression and high efficiency; the sealing sheet at the tips of the rotors also reflects the pressure of the working face so as to automatically adjust the contact pressure with the cylinder wall and fulfill the same purpose as the rotor design purpose; and the timing groove is formed on the sealing face of the rotors to allow increasing the overlapped area of the sealing face of the rotors and an inlet / outlet so as to increase the sealing property.

Description

technical field [0001] The invention relates to an active gap compensation type cycloid pump / motor device. Background technique [0002] Today's internal combustion engines have similar cycloidal pump / motor devices used in vehicles, and the intake and exhaust are generated every 360 degrees of the crankshaft angle. The rotor structure is a fixed thickness of the rotor, and the airtight requirements of the rotor side wall are pre-pressed by wave springs. The air-tight ring is not the entire rotor surface of this design, and the air-seal sheet at the tip of the rotor is also preloaded by a wave spring instead of the air pressure adjustment of this design. The airflow outlet of the internal combustion engine is set on the cylinder wall. The port will temporarily cause the air chambers to communicate with each other. The relative speed of the air seal at the tip of the rotor and the cylinder wall varies according to the angle due to eccentric operation during operation, so the c...

[0002] Today's internal combustion engines have similar cycloidal pump / motor devices used in vehicles, and the intake and exhaust are generated every 360 degrees of the crankshaft angle. The rotor structure is a fixed thickness of the rotor, and the airtight requirements of the rotor side wall are pre-pressed by wave springs. The air-tight ring is not the entire rotor surface of this design, and the air-seal sheet at the tip of the rotor is also preloaded by a wave spring instead of the air pressure adjustment of this design. The airflow outlet of the internal combustion engine is set on the cylinder wall. The port will temporarily cause the air chambers to communicate with each other. The relative speed of the air seal at the tip of the rotor and the cylinder wall varies according to the angle due to eccentric operation during operation, so the centrifugal force it receives is also different, which will cause uneven wear on the cylinder.
