摘　　要：针对液压自由活塞发动机和液压约束活塞发动机在关键技术和产业化方面出现的问题,创新性地提出了缸间齿轮联动液压发动机的结构原理,在此基础上对作为影响缸间齿轮联动液压发动机整机性能关键部件的缸间齿轮齿条传动机构和液压配流系统进行了结构设计与研究。缸间齿轮齿条传动机构采用正变位直齿圆柱齿轮和标准齿条无侧隙啮合传动,通过合理选择几何参数和强度校核,其能够支持发动机正常稳定运转;设计了一种往复柱塞泵用转套式配流系统,能够实现单向吸油和泵油,完成动力输出,且容积效率高、结构紧凑,相较于传统阀配流往复柱塞泵配流结构优势明显。缸间齿轮联动液压发动机的结构设计与研究为随后的整机性能研究、仿真优化和样机试制提供了参考依据。The structure and working principle of the Gear-linked Cylinders Hydraulic Engine （GCHE） is put forward creatively for the issues appearing in the critical technologies and industrialization of the Hydraulic Free Piston Engine （HFPE） and the Hydraulic Confined Piston Engine （HCPE）. And a structure researching design of the rack and pinion mechanism between cylinders and the hydraulically orifice system which play important roles in the engine performance has been conducted on the basis. The rack and pinion mechanism takes the method of positive displacement spur gear and standard rack no backlash meshing. With the geometric parameters selected and the strength check done reasonably, the mechanism is able to support normal and stable operation of the engine. Meanwhile, a rotating sleeve type hydraulically orifice system for reciprocating piston pump is designed, it can implement unidirectional suction and pump oil to complete the power output with high volumetric efficiency and compact structure and has obvious advantages compared to traditional valve type orifice system. The structure design and research of the Gear-linked Cylinders Hydraulic Engine （GCHE） provides reference for the later overall performance research, simulation and optimization and prototype trial.
