Abstract
The utility model relates to a double crank three cylinder compressor, which is the improvement of a gas or a liquid compressors. The utility model adopts two crank pins and three sets of plunger connecting rod mechanisms. The two crank pins are paralleled with the shaft line of a crank shaft in 180 DEG, and the working cylinder of one set of the plunger connecting rod mechanism is perpendicular to the shaft line of the crank shaft. The two working cylinders of another two sets of plunger connecting rod mechanisms are in 30 DEG with the shaft line of the crank shaft; the cylinders are arranged in a W shape. The double crank three cylinder compressor has the advantages of reasonable structure, small size, light weight, and energy saving.
Description
The utility model belongs to the improvement of gas or hydraulic compressor.
Present three turn three cylinder connecting rod compressors, and inblock cylinder is classified yi word pattern as, and crank pin distributes and crankshaft center line 120 degree; Its shortcoming is that volume is big, and bent axle is long, manufacturing process complexity, cost height, as shown in Figure 1, singly turn three cylinder connecting rod compressors, all on a crank pin, piston is distributed on the circumference of 60 °～60 °～240 ° of unequal-intervals three connecting rods, flywheel is heavy, bumpy motion, and consumed power is big.Piston rises continuously and descends, and makes respirating tube discharge capacity, suction amount big, causes consumption of lubricating oil excessive.See shown in Figure 2.
The purpose of this utility model is the shortcoming that overcomes above-mentioned compressor, and a kind of crutches three cylinder W type connecting rod compressors of new structure are provided.
The purpose of this utility model is to realize like this.
A kind of compressor of being made up of crank pin, piston crank mechanism, cylinder 9,10,11, bent axle 13, crankcase 12, flywheel 15, valve 16, cylinder cap 17 has two crank pins, 1,2, three cover piston crank mechanisms, and inblock cylinder is classified the W type as.The one cover piston crank mechanism crank pin that is slidingly connected, its working cylinder is fixedlyed connected with crankcase, and working cylinder is vertical with crankshaft center line; A separate set of piston crank mechanism parallel sliding connects another crank pin, and two working cylinders are fixedlyed connected with crankcase in addition, and two working cylinders become 30 ° of angles with crankshaft center line; Two crank pins on the bent axle are parallel to crankshaft center line 180 degree.
The compressor of this structure turns three cylinder compressors and compares with three, 3 times of crank pin hypotelorisms, and the main frame length overall shortens 1/3.Because bent axle shortens, and has increased intensity, has alleviated weight.Compare with singly turning three cylinder compressors, bent axle whenever circles, and three pistons compress once on 120 degree circumference respectively, and piston force is uniform on 360 degree circumference, and running is stable, and balance quality is good, has alleviated the weight of flywheel, has saved the energy.Because distributing, piston motion equates, space steady air current in the crankcase, and respirating tube discharge capacity and consumption of lubricating oil are also stable.This compressor arrangement is reasonable, and volume is little, and is in light weight, makes that simple economy is profitable to be mainly used in small-sized compression
Fig. 1 three turns three cylinder compressor connecting rod schematic representation;
Fig. 2 singly turns three cylinder compressor connecting rod schematic representation;
Fig. 3 is crutches three cylinder compressor connecting rod schematic representation;
Fig. 4 is crutches three cylinder compressor structural drawing.
1,2 crank pins, 3,4,5 connecting rods, 6,7,8 pistons, 9,10,11 cylinders, 12, crankcase, 13, bent axle, 14, crank pin, 15, flywheel 16, air valve, 17, cylinder cap.
The utility model is provided by following examples.
With the mini air compressor is example:
Air compressor is by crank pin 1,2, connecting rod 3,4,5, and piston 6,7,8, cylinder 9,10,11, crankcase 12, bent axle 13, flywheel 15, air valve 16, cylinder cap 17 is formed.Adopt two crank pins, three cover piston crank mechanisms.Cylinder is arranged for the W type.One cover piston crank mechanism 3,6 crank pin 1 that is slidingly connected, piston 6 working cylinders 9 are fixedlyed connected with crankcase 12, the axis normal of cylinder 9 and bent axle 13.A separate set of piston crank mechanism 4,7,5,8 crank pin 2 that is slidingly connected, piston 7,8 working cylinders 10,11 are fixedlyed connected with crankcase, and cylinder 10,11 is arranged with crankshaft center line and is become 30 to spend angles.Two crank pins 1,2 on the bent axle are parallel to crankshaft center line 180 degree.Other structure of former air compressor does not change.
Claims (1)
1, the compressor a kind of by the crank piston crank mechanism, that cylinder, bent axle, crankcase, flywheel, valve, cylinder cap are formed is characterized in that having two crank pins, three cover piston crank mechanisms; Inblock cylinder is classified the W type as;
The one cover piston crank mechanism crank pin that is slidingly connected, its working cylinder is fixedlyed connected with crankcase, and working cylinder is vertical with crankshaft center line;
