Abstract
The utility model comprises a piston, a piston rod, a two side elliptical cam, a machine body, a slide block, a guide plate, a straight shaft, a shaft pin, etc. The piston and piston rod are in fixed connection; the piston rod and the shaft pin are in movable and fit connection. The guide plate is fixed on the machine body; fixed at the lower end of the piston rod, the slide block can slide along the guide plate. The two side elliptical cam is fixed on the straight shaft; the inner side of the straight shaft is provided with an elliptical and annular groove; when driven by the elliptical and annular groove of the two side elliptical cam to do upward and downward movement, the self of the shaft pin below the piston rod also rotates. The utility model has the advantages of simple structure, easy fabrication, convenient assembly, convenient disassembly, light weight, stable operation, high power and uniform output of the power, and is suitable for the drive conversion of a reciprocating engine.
Description
The utility model relates to a kind of cam power switching device of cam power switching device, particularly Reciprocating engine.
As everyone knows, traditional Reciprocating engine moves with crankshaft ﹠ connecting and realizes power-converting.Its deficiency is a complex structure, and volume is big, manufacturing, maintenance dismounting difficulty, cost height.
The purpose of this utility model provides a kind of simple in structure, in light weight, easy to manufacture, maintenance easy accessibility, cam power switching device that cost is low.
The purpose of this utility model is realized by following scheme: it comprises piston, piston rod, two-sided elliptic cam, body, slide block, guide plate, d-axis, pivot pin etc.Piston is fixedlyed connected with piston rod, and piston rod is connected movingly with pivot pin.Guide plate and slide block are in two neutral gears between the two-sided elliptic cam, and guide plate is fixed on the body, and slide block is fixed on the lower end of piston rod, can slide along guide plate, bear side-thrust.Slide block both can be the single-acting formula, also can be (promptly can be double-face or one plane type) of double action.Two-sided elliptic cam is fixed on the d-axis.There is oval annular groove two-sided elliptic cam inboard, and the pivot pin under the piston rod places in the oval annular groove, self also rotates when being moved up and down by the action of elliptical ring troughed belt.
When the major axis of two-sided elliptic cam turned to substantially horizontal by Vertical direction, it was descending to drive piston rod, and piston moves downward finishes a stroke; When the major axis of two-sided elliptic cam turned to Vertical direction by substantially horizontal, piston moved upward and finishes a stroke.Be that two-sided elliptic cam rotates 90 degree, piston is finished a to-and-fro motion stroke, and two-sided elliptic cam rotates a week, and piston is finished four strokes.
When being used for multicylinder engine, the two-sided elliptic cam of each cylinder sequencing by power stroke is together in series with d-axis.
The utility model has been owing to replaced crankshaft ﹠ connecting and Equilibrator with two-sided elliptic cam device, thereby simple in structure, easy to manufacture, and the maintenance easy accessibility is in light weight, running steadily, power output is even.Because two-sided elliptic cam rotates and can finish four stroke of piston a week, thereby compares with the motor with crankshaft ﹠ connecting of same swept volume and rotating speed, power doubles.
Fig. 1 is a double-track cam power switching device structural representation;
Fig. 2 is the front view of double-track cam;
Fig. 3 is a double-track cam power switching device sectional arrangement drawing.
The utility model is described in further detail below in conjunction with accompanying drawing: it comprises piston 1, piston rod 2, two-sided elliptic cam 3, pivot pin 4, body 5, slide block 6, guide plate 7, d-axis 8 etc.Piston 1 is fixedlyed connected with piston rod 2, and piston rod 2 is connected movingly with pivot pin 4.Guide plate 7 and slide block 6 are in two neutral gears between the two-sided elliptic cam, and guide plate 7 is fixed on the body 5, and slide block 6 is fixed on the lower end of piston rod 2, can slide along guide plate 7, bear side-thrust.Slide block 6 both can be the single-acting formula, also can be (promptly can be double-face or one plane type) of double action.Two-sided elliptic cam 3 is fixed on the d-axis 8.There is oval annular groove 9 two-sided elliptic cam 3 inboards, and the pivot pin 4 under the piston rod 2 places in the oval grooved ring 9, self also rotate when being moved up and down by oval annular groove 9 drives.
When the major axis of two-sided elliptic cam 3 turned to substantially horizontal by Vertical direction, oval annular groove 9 moved downward pivot pin 4 and piston rod 2, and piston 1 moves downward finishes a stroke; When the major axis of two-sided elliptic cam 3 turned to Vertical direction by substantially horizontal, piston 1 moved upward and finishes a stroke.Be that two-sided elliptic cam 3 rotates 90 degree, piston 1 is finished a to-and-fro motion stroke, and two-sided elliptic cam 3 rotates a week, and piston 1 is finished four strokes.
When being used for multicylinder engine, the two-sided elliptic cam 3 of each cylinder sequencing by power stroke is together in series with d-axis 8.
