Abstract
The facing walls (4) of the columns of a crosshead piston machine which receive the normally directed crosshead journal forces are supported on a box section comprising side walls (6) and outer walls (3). In the vertical direction the side walls (6) incline outwards towards the free ends of the facing walls (4). The box section therefore widens in the zone of maximum normal- acting forces i.e., near the top dead centre position of the piston - but no increase in engine length is necessary for this purpose. The widening of the box section reduces load-induced deformations of the facing walls (4), particularly at their ends.
Description
The column of supporting crosshead guide bar slide rail in the relevant Reciprocating engine of the present invention, column has outer wall slant dilation between base plate and cover plate, the sidewall that stretches on whole height links to each other vertical end wall with outer wall, end wall is on a part of height on their the relative face, the guide rod slide rail is arranged, the power that acts on the crosshead journal Normal direction, be delivered to column and get on.
Traditionally, in order to accept to act on the normal, and along being passed to the power on column or the supporting element perpendicular to Reciprocating engine (particularly a little oily machine) crosshead guide bar slide rail direction, not only need be on the height of guide rod slide rail the horizontal strengthening rib of configuration level, or between end wall and side wall ends, the reinforced wall (seeing Swiss Patent CH-PS625, No. 603) of vertical stretching is set with acutangulating.Can find that the structure of above narrating is very expensive.
And the Reciprocating engine claimed structure is very compact, requires to have between the cylinder very short distance.This distance depends on necessary main bearing length, the summation of lower link bearing length and two crankweb sizes.Therefore, if require the not length of " waste " motor, sidewall is in the bottom, near the close bent axle, and must be very close.
Therefore purpose of the present invention is the contour structure of simplifying the device that supporting guide rod slide rail is set, and does not cause the excessive distortion of end wall, does not also increase the length of motor.Therefore,, support the sidewall of an end wall in couples, towards the sloped-end stretching, extension of end wall according to the present invention.
Certainly vertically act on the guide rod slide rail, thereby also act on power on the end wall,,, in this zone, form one by end wall, the relative wide casing that outer wall and both sidewalls are formed by the sidewall structure that the present invention proposes in the top dead center maximum of piston motion.Near the upper dead center position of piston, sidewall supports end wall near the end wall free end, and distortion is remained in the relatively little limit.
Hereinafter, the present invention is done more detailed narration with reference to an embodiment and accompanying drawing.Accompanying drawing thes contents are as follows:
Fig. 1 is single column in the diesel engine, along the schematic cross-section of the I among Fig. 2-I line;
Fig. 2 has crosshead for the sectional view of bowing of motor two adjacent upright along II-II line of Fig. 1 between two columns;
Fig. 3 is the sectional view of Fig. 2 along III-III line.
The column that known structure is arranged for example is made of the steel plate welding, and this column has base plate 2 and both sides inclination outer wall 3 and vertical end wall 4 to connect formation, forms on two Vertical direction to be trapezoidal support body.Connect by a common cover plate 5 between the support body.Sidewall 6 makes it become a complete trapezoidal support body between outer wall 3 and sidewall 4.Coupling rod or stud bolt 7 or like parts (Fig. 2) are placed between the sidewall 6, with prestressing force stationary engine cylinder head (do not give among the figure and illustrating).
With bearing shell 14 bent axle 16 is installed in the substrate 1, bearing shell 14 has the first half and Lower Half, lays a bearing cap 15 on the bearing shell.
As can be seen from Figure 3, cylinder the length m of the motor that must have mainly comprise half h/2, the length S of the lower bearing 18 of connecting rod 20 and the thickness d of two crankwebs 17 of the length of both sides main bearing 14.The front was carried, each cylinder the length requirement of the motor that must have very little.
Partly locate in the middle of between end walls 4, have a midfeather 8 to replace sidewalls 6, the underpart of midfeather 8 is provided with an apart transverse support plates 9.As can be seen from Fig. 2, on two relative faces of the end wall 4 of two columns, form the guide rod slide rail of the slider 10 of crosshead journal 11, crosshead journal 11 is connected with piston rod 12 in a known manner, and is installed in the cartridge housing 13.
According to the present invention, two side 6 is left one section distance that only can supply tie-rod or stud bolt or like parts 7 to pass through from the inside mutually in the bottom.Sidewall 6 tilts to place, upwards mutually away from so that one with upper dead center mutually in the contiguous area (this zone is in Fig. 1 and 3 li positions that are approximately the crosshead place) near the free end of end wall 4, support end wall 4.Therefore wall 3,4 forms a relative wide rigidity " casing " with 6 in above-mentioned zone, and the length m of motor is increased.
Spacing wall 19 is arranged in the space between the sidewall 6, strengthens by " casing ", so that improve the rigidity of the sizable sidewall of area in the zone of high load.
Claims (1)
1, a kind of column that supports Reciprocating engine crosshead guide bar slide rail, column has the outer wall of slant dilation between base plate and cover plate, and stretches on whole height, by the vertical end wall of sidewall connection; End wall is also made the guide rod slide rail that is oppositely arranged on its a part of face highly, its is delivered to normal force of acting on the crosshead journal on the column, it is characterized by the sidewall (6) that supports an end wall (4) in couples and stretches towards the sloped-end ground of end wall.
