Description
Technical field
The present invention relates to a kind of free-piston internal combustion power generation power system piston assembly phase locking system, belong to the energy source and power field.
Background technique
Free-piston internal combustion power generation power system is a kind of novel power device of rising in recent years, and its whole system comprises internal-combustion engine and linear electric motor two big modules.Generally directly link to each other by connecting rod between internal-combustion engine module and the linear electric motor module, the mechanical energy that the former is transformed by heat energy can be converted into electric energy and outwards output in linear electric motor.Have benefited from its short power conveyer chain, its mechanical loss is lower than traditional type.Thereby on overall efficiency, the free piston IC power generation power system has higher room for promotion.Reply energy problem, it also has bigger potentiality.
A kind of scheme that the generator module of free-piston internal combustion power generation power system adopts usually is cylindrical linear, and the basic configuration of its internal-combustion engine module is consistent with traditional type, is circular cylinder and piston assembly.Simultaneously, the working method of internal-combustion engine module much all adopts the two stroke operation form.For the two stroke operation mode, piston is also born the effect that each gas port of control cylinder opens and closes except playing the effect of bearing cylinder pressure and acting, so the piston ring on the piston will produce friction with the casing wall gas port.In general the otch of piston ring should be avoided each gas port phase place of living in, avoids otch and gas port to produce violent friction and makes cylinder inner wall impaired.On traditional type, because the rotation centered by cylinder-bore axis can not take place connecting rod, so piston ring otch phase place of living on the piston side circumferential surface can guarantee that its phase place is forever stable by the bayonet lock on the piston and fixing piston assembly phase control.
Yet on free-piston internal combustion power generation power system internal-combustion engine module, because two big module inboards are circle, piston assembly can rotate around cylinder-bore axis, thereby the piston assembly phase place can't lock.Can't extremely accurately control because of the processing of the connecting rod screw thread between piston and the linear motor rotor again simultaneously, thereby after screwing, the phase place of piston pin boss can't be determined equally.Two kinds of factors all cause and have worsened wrist pin phase place lock condition, influence piston ring phase place lockout issue then.So in free-piston internal combustion power generation power system working procedure, the piston ring phase place occurs and can't keep same all the time, cause its internal-combustion engine module the phenomenon that the inside wall of cylinder is pulled often to occur.
Summary of the invention
The objective of the invention is to propose a kind of free-piston internal combustion power generation power system piston assembly phase locking system for solving the piston assembly phase place lockout issue of free-piston internal combustion power generation power system in the prior art.
The objective of the invention is to be achieved through the following technical solutions.
A kind of free-piston internal combustion power generation power system piston assembly phase locking system comprises two side rails, side guide rod, adjustable phase connection rod set, and the adjustable phase connection rod set comprises piston pin boss, screw shell, base.
The side guide rod is positioned at the middle and lower part of piston pin boss, passes the through hole, vertical with piston pin boss of side; Two parallel symmetries of side rails are positioned at the piston pin boss both sides, and side rails is the L type, and two side rails are inserted at the two ends of side guide rod respectively; The bottom mounting base of piston pin boss all has the radial wave Slippage on the bottom circumference of the inboard and piston pin boss of base, both interlocks of aliging; Half of the maximum piston component erroi phase angle that angle intervals between adjacent two crests of described radial wave Slippage allows less than system.
Screw shell is the cylindrical body of hollow, and there is screw thread the inboard.Be a screw rod between the bottom of piston pin boss and the side guide rod, the screw thread phase interlock of screw flight and screw shell, screw rod passes the hollow round hole of screw shell, screws closely with the wrist pin base, forms the adjustable phase connection rod set.
Free-piston internal combustion power generation power system piston assembly phase locking system of the present invention, its mode of action is: the bottom circular aperture that screw shell passes with the screw rod of base bottom in elder generation.Then according to needed piston assembly locking condition, with the radial wave Slippage of the radial wave Slippage of wrist pin base and base by the designated phase interlock of aliging.The inner side surface screw thread of screw shell and wrist pin base side threaded engagement screw closely, form the adjustable phase connection rod set, again with side guide rod inserting side guide rail.Short end with L type side rails is fixedly installed on the linear motor stator electric at last, and is the horizontal symmetrical state.This device of cover is arranged at the linear electric motor two ends of each free-piston internal combustion power generation power system respectively.
Beneficial effect
Free-piston internal combustion power generation power system piston assembly phase locking system of the present invention has been realized the locking of both sides piston assembly phase place under the system applies condition, has further guaranteed the piston ring phase place locking of two-stroke piston.The final realization avoids piston ring otch and cylinder port edge to rub.
This apparatus structure is simple, has high reliability, is convenient to make produce, and is easy to realize.
