Definitions

  • the inventive mechanism for converting the movement of the engine contains a closed circuit in which intermediate sliders with upper (1) and lower (2) rolling elements are included, which by means of flexible rods (3), thrust bearing systems (4) and scaling block systems (5) connected with groups of working pistons (6), pistons communicate with flexible rods through rigidly connected to them • rods, one of the ends of which passes through the combustion chamber;
  • the connecting rods are upper (8) and lower (9), upper (connected to the sliders) (10) and lower (connected to the shaft) (11) the heads of which are connected by flexible rods (12), the lower heads of the lower connecting rods being bifurcated, and lower heads of the upper connecting rods are installed between the forked parts of the lower head of the lower connecting rods;
  • the lower connecting rods of the first type (non-divided) (13) and the second type (divided) (14) are movably (freely rotated around their axis) are installed in the disks of the first type (15) and of the second type (16) fixedly mounted in the inner cages of
  • the invention relates to mechanical engineering, namely to reciprocating internal combustion engines with a cyclic nature of work, with a piston reciprocating. It can be used both in a diesel engine ⁇ and in an engine with spark ignition, in a two-time and four-time engine, in vehicles and stationary vehicles.
  • crank mechanism has a significant drawback - with its help it is impossible to obtain an increase in efficiency and power.
  • An increase in efficiency and engine power is achievable only for due to changes in the regime of thermochemical processes occurring in the cylinder.
  • the aim of the invention is to eliminate this drawback, i.e. increase in efficiency and engine power without changing indicator operation using the proposed conversion mechanism.
  • the essence of the invention lies in the fact that the relationship between the rectilinear reciprocating motion of the slider and the rotational movement of the shaft is carried out by means of a thrust, and not a push, which takes place in engines with a known crank mechanism.
  • the change in the nature of the applied effort is based on the application of the properties of flexible rods.
  • the use of flexible rods makes it possible to change not only the nature of the applied force, but also it is advantageous to convert the ratio of two main parameters (crank diameter D and slider stroke length H) of piston engines.
  • a k-fold increase in the force acting on the piston associated with an increase in the piston area and a k-fold increase in the number of complete cycles associated with a decrease in the path traveled by the piston leads to k 2 - a multiple increase in the power of the proposed engine in comparison with known engines with equal cylinder displacement.
  • the most loaded part is the intermediate sliders, whose speeds are k-times higher than the speed of the working piston, but on the other hand there is the possibility of using higher kinematic pairs and there is no high thermal load, which opens up wider possibilities in the choice of design and structural materials.
  • the proposed engine also implements another possibility for increasing power and efficiency, also based on purely constructive means and connected with the idea of a variable length of the crank, creating a variable-length arm.
  • the shoulder increases, in compression, it decreases, as a result of which the total torque, and, consequently, the efficiency and output of the engine increases in comparison with an engine with a well-known crank mechanism.
  • the essence of the implementation of this feature is that the conversion mechanism has two rotation axes, while the shaft is dissected and modified.
  • the mechanism comprises an elongated lower connecting rod pin of the first type (non-divided), connected through the disks of the first type with the inner race of two coaxial limiting bearings of the first type.
  • the axis of the finger is a generator that performs a circular rotation, the diameter of which is equal to the stroke of the intermediate slider. This is the first axis of rotation (I) of FIG. 1 and 2.
  • rocker stones are placed that go into the slot of the rocker, made in the disks rigidly fixed in the inner race of two coaxial main bearings.
  • the main bearing axis is the second rotation axis (O) of FIG. 1 and 2.
  • the axis of the main bearings is inside the circle of rotation of the lower pin of the connecting rod. Due to the displacement of the axis of the main bearings relative to the first axis (the axis of the limiting bearings) of rotation during operation of the engine, the rocker stones move in the slots of the rocker, thus creating a shoulder of variable length.
  • the conversion mechanism also contains lower connecting rod pins of the second type (dissected) connected through disks of the second type with internal cages of coaxial limiting bearings of the second type, differing from limiting bearings of the first type with a diametrically opposite displacement relative to the axis of the main bearings.
  • the lower connecting rod fingers are divided into three parts: the middle, which is connected by the lower connecting rod heads and through the discs of the second a type with internal cages of limiting bearings of the second type and two extreme or rocker parts, which at one end connect to the rocker stone, and the other to one of the disks of the second type.
  • the presence of two lower crank pins, the corresponding design features of the discs, as well as the presence of two types of limiting bearings are associated with the need to coordinate the operation of the incoming piston, whose compression stroke occurring on the shortened shoulder is superimposed on the stroke of the subsequent piston running on the elongated shoulder.
  • the coordination also provides unidirectional movement of the shaft clockwise if the axes of the limiting bearings of both types are displaced relative to the axis of the main bearings along the line passing through the first and third quarters of the plane of rotation and counterclockwise if this line passes through the second and fourth quarters of the plane of rotation.
  • Both types of limiting bearings can be connected to the inlet piston and, accordingly, if the same type of limiting bearings are connected to the entering piston, then all subsequent odd f pistons are connected to the same type of limiting bearings, and all subsequent even pistons are of the other type of limiting bearings.
  • the lower connecting rod pin of the first type To balance the centrifugal forces arising from the movement of the connecting rods, the lower connecting rod pin of the first type, rocker stones and bumps at the points of connection of the lower connecting rod pin of the first type with the disk of the first type, the latter is equipped with corresponding counterweights (24) of FIG. 2.
  • Disc counterweights of the second type (25) of FIG. 2 provide balancing of the centrifugal forces arising from the movement of the connecting rods, the middle part of the lower connecting rod pin of the second type and the thickenings at the points of connection of the middle part of the lower connecting rod pin of the second type with the disks of the second type, given that the rocker stones and the extreme or rocker parts of the lower connecting rod pin of the second species are part of the counterweight.
  • Disks of the first kind (22) of the first motionlessly fixed in the inner race of the main bearings of the bearings 2 (extreme) are rigidly connected to dissected parts of the shaft, front and rear, which is connected to the drive shaft of the gearbox.
  • Disks of the second type (23) of the second motionlessly fixed in the inner bearings of the main bearings of FIG. 2 (medium) are rigidly interconnected, thereby combining into a single design the dismembered parts of the modified shaft, which differs from the traditional crankshaft in a different load distribution attributable to the crankshaft main necks.
  • the engine operates as follows.
  • the upper block of the system of scaling blocks moving down selects the flexible rod by the difference between the stroke length of the upper intermediate slide and the stroke of the working piston, and the lower block, connected with the upper block by the flexible rod, also moving down, compensates for the difference between the stroke length of the lower intermediate slide and stroke length of the working piston.
  • the lower connecting rod pin under the action of limiting bearings, the axis of which is offset from the axis of the main bearings, moves the rocker stones in the slots of the wings, either removing them from the axis of the main bearings, thereby increasing the shoulder and torque, or bringing it closer to the axis of the main bearings, thereby reducing shoulder and torque required to perform compression work.
  • the proposed engine has a fairly close analogue (patent RU Jfe 2018009 and US JN 1595917 class F 02b75 / 32), the essence of which is that the conversion mechanism also has two axis of rotation and the shaft is also dissected.
  • the mechanism also contains an elongated connecting rod pin (of the same type, corresponding to the lower connecting rod pin of the first type - undifferentiated), also connected to the inner race of one (and not two as in the proposed engine) limit bearing (one type - corresponding to the limit bearing of the first type in the proposed engine) .
  • the axis of the lower finger is also a generatrix, which performs a circular rotation, the circumference of which is equal to the length of the piston stroke.
  • rocker stones are also placed that go into the slots of the wings, which are the knees of the shaft and rigidly connected with the dismembered parts of the shaft (in the proposed engine, the main shaft neck with the knees is replaced by a main bearing with a disk).
  • the shaft axis is also located inside the circle of rotation of the lower connecting rod pin.
  • each cylinder has one limiting bearing (there are two of them in the proposed engine) placed between the bifurcated lower parts of the connecting rod, which does not allow the limiting bearing to be fixed around the entire circumference of the outer race in the engine housing and about a quarter of the circumference of the outer race of the bearing has no support.
  • This calculated indicator of 2.56 can serve as a baseline for an approximate estimate of the increase in efficiency and power introduced into the proposed engine by the idea of a variable crank length. Given the difference in the nature of the applied force, the projection of which onto the tangential direction at the starting point during traction is less than during the push, as well as the randomness of the choice of the displacement of the rotation axes (it’s not optimal), it is possible to take with a greater degree of confidence the value of the power increase and efficiency for the proposed engine equal to ⁇ 2.
