Teeth synergistic three-dimensional wobble plate piston engine

Abstract

The invention discloses a tooth-cooperated three-dimensional wobble plate piston engine, which includes a base body, a main shaft, a cylinder body, a transmission assembly and a cooperating tooth assembly; the cylinder body includes at least two cylinders arranged in a circular array in parallel around the central axis, and the transmission assembly includes a wobble plate , the cooperative tooth assembly includes a first bevel gear fixed on the wobble plate and a second bevel gear fixed on the cylinder body, the first bevel gear and the second bevel gear form meshing, so that the wobble plate and the cylinder Synergy is formed between the cylinders in the circumferential direction, so as to coordinate the synchronization between the cylinder and the swing plate in the circumferential direction, so that the connecting rod only transmits the reciprocating driving force, and does not participate in the transmission of the synchronization of the swing plate and the cylinder in the circumferential direction. load, remove the commonly used sliding shoe structure in the prior art, simplify the connection relationship between the connecting rod and the piston, and the connecting rod and the swing plate, so that the overall structure is simple and light, prolong the service life of the connecting pair, and save manufacturing and use costs. The invention adopts the rotary cylinder gas distribution structure, which is compact, simple, high power-to-weight ratio, large power-to-volume ratio, small radial load of the piston, and high mechanical efficiency of the whole machine; Small resistance, suitable for aero-engines.

Description

technical field [0001] The invention relates to the field of transmission drive, in particular to a three-dimensional wobble plate piston engine coordinated by teeth. Background technique [0002] The axial piston device is driven or driven by a cylinder arranged around a central axis, a piston matched with the cylinder, and a rotating wobble plate; the basic structure is that the piston is connected to the wobble plate through a connecting rod, and the reciprocating motion of the piston is transmitted to the oscillating plate through the connecting rod. The disk is transformed into a rotational output by using the cam transmission principle of the wobble disk; or, the wobble disk is driven by the periodic axial swing to periodically change the axial position and drive the piston through the connecting rod to form a reciprocating motion and perform work. [0003] From the above structure, it can be seen that relative to the cylinder body, it is expected that there will be no...

Problems solved by technology

[0003] From the above structure, it can be seen that relative to the cylinder body, it is expected that there will be no relative rotation in the circumferential direction between the wobble plate and the cylinder body. The piston still transmits the power of the piston to the wobble plate, and the wobble plate is subject to the component force in the circumferential direction. Therefore, the connecting rod also constrains the coordinated action between the wobble plate and the cylinder (piston), so the bearing is more complicated and has various directions. The deflection moment; therefore, the usual structure adopts the sliding shoe structure to adapt to the azimuth change in all directions and undertake more complex deflection moment, the structure is more complicated; the sliding shoe structure needs to have sufficient lubrication, which not only makes the structure extremely complicated, but also prone to occurrence Wear leads to machine failure; due to the above problems, the existing technology is rarely used in the case of engines, high speed and load will quickly fail the axial piston structure
