Description
The present invention relates to a kind of crosshead of two-stroke piston engine and coupled piston rod, crosshead comprises a cross head bearing that is fixed on the connecting rod and belongs to the crosshead pin pattern that has a central part, this central part is bearing on the bearing with its total length basically and has two respectively with the end of journal rest on corresponding guide shoe, this bearing has a recess up, crosshead pin has the surface of bottom side, a supporting piston bar lower end, the recess in the bearing is stretched in described lower end, and oil supply pipeline with oil supply with one in crosshead the distributing groove road and be fixedly linked on engine stand with the one end.
In large-scale low speed internal-combustion engine, for example shiphoard machinery system or fixed power generation factory, there is a kind of old-fashioned engine type of knowing that has a crosshead, wherein crosshead pin is to be fixed on the piston rod like this, even bolt is upward through crosshead is screwed into piston rod in the center bottom from below.Crosshead pin is arranged in the respectively cross head bearings that separate an of side of piston rod with journal rest at two, and two bearings all are fixed on the connecting rod, thereby providing enough spaces between the bearing in order to an oil supply pipeline is securely fixed in the middle part of the crosshead pin between two journal surfaces with bolt, and an oil-drain pipe is securely fixed in the middle part of crosshead pin opposite side by a backup flange with bolt, oil-drain pipe connects the oil outlet of a side direction at the lower end of piston rod.Oil-drain pipe is that the short pipe fitting of a lightweight bears oily slotted pipe with one of oil guiding.Described old-fashioned crosshead motor vertically on size very big because effectively bearing area entirely is positioned at the both sides of piston rod.
The size of up-to-date motor is set at the twice near the pressure maximum in the working cylinder, and the power by crosshead sends bears high like this requirement, and in order to have enough big area, its underpart must be continuous.This just causes developing the crosshead of the sort of type that beginning mentions, and one of them can allow that the oil supply pipeline transition with enough width fixed thereon partly is arranged on each termination partly and between the central part.The fixing conduit of lubricant oil in the engine stand flow to crosshead by the oil supply pipeline that is fixed in the transition partly between guide shoe and the bearing, and the distribution piping in the oil supply pipeline of this inclination and many crossheads is sent to the bearing surface of crosshead and the oil duct in connecting rod and the piston rod with oil.Oil flows to piston by a pipe that is positioned at the piston rod center and flows away from piston by an annular pass that is holding this pipe, this annular pass that is positioned at the piston root is converged with two longitudinal passages that separate and is continued to flow into crosshead pin, the path that they converge again by many levels at this place enters a common discharge aperture that is positioned at second transition part, and an oil-drain pipe is fixed on the opening.
Oil supply pipeline be fixedly connected on simultaneously on the engine stand and crosshead on, therefore oil supply pipeline must the bumpered cross head with respect to the motion of engine stand, this just requires oil supply pipeline to have the shape of very strong structure and pipe, thereby overweights the weight of waste oil discharge tube.Because oil supply pipeline has bigger quality, therefore higher to the requirement of strength of its fastening piece, so fastening piece is just inevitable very heavy.The general embedding of recess of the admittance piston rod on crosshead top drop on the middle part of bearing and in the axial direction by two tops along the crosshead pin periphery go in ring the bearing termination of extending partly institute define.
The purpose of this invention is to provide a kind of piston-engined crosshead and coupled piston rod, it is simple in structure, and the size on the longitudinal direction at motor under the situation of the load capacity that does not reduce bearing is less.
Crosshead of the present invention can realize this purpose, it is characterized in that lower end that oil supply pipeline extends to piston rod facing to an oil-feed opening, this opening by one in piston rod passage and the distribution piping in the crosshead join.
Proved and might make strength and stiffness all be placed in the lower end of piston rod than higher oil supply pipeline, the transition of crosshead pin partly can be removed, and the termination partly can be placed in the direct extension partly of central part, thereby makes the axial length of pin reduce partly this length partly of transition.The distance that short crosshead pin could be used to or reduce engine cylinder has reduced the whole erection length of motor thus, thereby the length that has perhaps increased central part has increased the loaded area of crosshead.Because lubricant oil is supplied to piston rod, partly promptly no longer needed to the supply line of distribution piping from the termination of pin, thereby the manufacturing of pin has also just been oversimplified.
Piston rod can be designed to have a lower flange, its edge surface is placed in the recess of bearing basically, in this situation, oil supply pipeline preferably is fixed on this edge surface, so that make the whole height of crosshead not be subjected to the influence of the position of the oil supply pipeline on the piston rod, this is very important for vertical placement piston rod stuffing box.
Crosshead top admits the recess of piston rod generally to be formed on the central position of bearing, and is defined along the belt bearing termination part that extends of crosshead pin peripheral upper portion by two in the axial direction.
For the present invention, the big as far as possible theory of bearing area needs that is considered to basic demand about the design of crosshead only is only applicable to the following part of bearing, and the engine cylinder that if partly bearing area is relevant above bearing pressurized operation not, then as long as enough make crosshead pin remain in the bearing appropriate location.When the axial width of each bearing termination part is below bearing partly in 15 to 30% of the bearing surface width the scope, when the radial height of bearing termination part was transferred to the width of selection, two bearing termination parts just have made pin remain on the required intensity in appropriate location.
Can provide a good support to heavier oil supply pipeline for the bearing area requirement of part above the crosshead is low, and do not need this support to increase the axial length of bearing itself, the feature of this crosshead is that in the part of bearing termination has a segment length of such groove so that crosshead pin central part to expose in its axial outside at least in a preferred embodiment, and support bracket that is used for oil supply pipeline is fixed on this section expose portion of crosshead pin, and its feature is that also oil supply pipeline is supported by bracket and has a termination part that is fixed on piston-rod lower end oil-feed opening.
The invention still further relates to the piston rod on a kind of crosshead that is used to be connected in the above-mentioned type, this piston rod has a central longitudinal on the bottom surface that terminates in piston rod to cavity.Piston rod is to produce as independent parts, and it can be installed on the crosshead pin.It is characterized in that according to the present invention this central authorities' cavity and one are positioned near the bottom and the horizontal cavity that leads to a fuel-displaced opening on an edge surface communicates, this edge surface is connected to an oil-drain pipe, and its feature is that also piston rod has an oil inlet passage to be connected to oil-feed opening on the edge surface of an oil supply pipeline from a preparation and extends to exhaust port in the piston rod bottom surface.Since its continuous central cavity that has a horizontal cavity and one can be used as one radially cavity converge simple structure into the passage of an axial cavity, the production of this piston rod is very simple.
Preferably can become communication type at the horizontal cavity of piston rod root from fuel-displaced opening to oil-feed opening, thus make root as much as possible symmetry to avoid owing to the different hardness of root makes the piston rod displacement.Connection between oil inlet passage and the oil discharge passage can be cut off by a sleeve, and one of this sleeve support is at the pipe of central cavity and extend upward through horizontal cavity.
