Description

Centripetal thrust osillating wheel

The utility model relates to a kind of escapement, mainly is used on air compressor, refrigerating machine and the various pump, to replace existing bent axle.

Existing air compressor, refrigerating machine all are to utilize crankshaft rotating drivening rod motion, make piston to-and-fro motion in cylinder sleeve, and by advancing of being connected with cylinder sleeve, valve goalkeeper gas sucks, discharge, and reaches the purpose of compression.Present employed oil pump, water pump also some be adopt bent axle drivening rod piston and by advance, the valve door reaches suctions, the purpose of discharge.In this structure, the processing technology of bent axle is very complicated, required precision is high, especially powerful compressor, and number of pistons is more.Can cause bent axle longitudinal length size big, processing difficulties also can cause the complete machine external dimension big simultaneously, and heaviness is difficult for transportation.

The purpose of this utility model provides the low centripetal thrust force escapement of the simple cost of a kind of processing technology, to replace existing bent axle.

Technical solution of the present utility model is: a kind of centripetal thrust force escapement, be fixed with 10 of swash plate 3 on the main shaft 1 respectively, and two relative inclined-planes on the swash plate 3 and 10 are parallel, and are with escapement 8 on the main shaft 1 between two relative inclined-planes.Be provided with thrust-bearing between the swash plate 3 and 10 of escapement 8 and both sides.The circumference of escapement 8 is provided with at least two cleviss 14 and a guide rod 7, and clevis 14 is provided with hole 13, and the inner peripheral surface of escapement 8 is a convex surface, swash plate 3 10 on the inclined-plane and the center line angulation of main shaft 1 be 8 °～15 °.

Be provided with cover 16 between the inner peripheral surface of described escapement 8 and the main shaft 1.

The utility model compared with prior art owing to be to be fixed with two relative swash plates on the main shaft of a straight line shape, is with escapement between two swash plates, and the circumference of escapement is provided with clevis and guide rod.Clevis links to each other with an end of connecting rod.The other end of connecting rod links to each other with piston, piston is positioned at the cylinder sleeve cover, because when main shaft rotated, two swash plates on the main shaft were by the action of rolling bearing clamping escapement, the cylindrical of escapement can be along the vertical to-and-fro motion of the shaft axis of main shaft, can drive reciprocating motion of the pistons by connecting rod, this structure has replaced existing bent axle, and its advantage is: processing technology is simple, reduces cost, axial dimension shortens, and makes machine volume little in light weight.

Below in conjunction with the drawings and the specific embodiments the utility model is further described:

Fig. 1 is that the utility model specifically is applied in the plan view on the air compressor;

Fig. 2 is an A-A sectional view shown in Figure 1;

Fig. 3 is a B-B sectional view shown in Figure 1;

Fig. 4 is a C-C sectional view shown in Figure 1;

Fig. 5 is the plan view of the utility model embodiment.

As shown in Figure 5: 1 is main shaft, 3,10 be steel No. 45 for the swash plate material, swash plate 3 is connected with main shaft key with 10, the inclined-plane opposing parallel of swash plate, with spindle axis wire clamp angle be 8 ° 11 ', fixed cover is connected to cover 16 on the main shaft between two swash plates, the material of cover 16 is a copper, also can select other high-abrasive material, material is that the escapement 8 of No. 45 steel is enclosed within outside 16, and the inner circumference of escapement 8 is convex surface (as shown in Figure 5), and the both sides of escapement 8 are inlaid with bearing housing 12 and 13, be inlaid with bearing housing 5 and 11 on the swash plate 3 and 10 too, and bearing housing fixed with pin 4.Being respectively equipped with bearing roller 6 and 9 between bearing

housing

5 and 13, between 11 and 12, form two groups of thrust thrust bearings.To guarantee that when main shaft rotates the swash plate that is fixed on the main shaft drives escapement 8 cylindricals along the vertical reciprocally swinging of the shaft axis of main shaft 1 by thrust-bearing.Be processed with the clevis 14 of U type on the cylindrical of escapement 8, its quantity is seven, and the top also has been threaded guide rod 7(shown in Fig. 2,5), clevis is equipped with the hole on 14 both sides.

As Fig. 1,2,3,4, shown in: to be applied on the air compressor is example: 18,19 be respectively cylinder body, bolt is connected with connecting body 20 between two cylinder bodies, and adopts locating stud 21,22 location.Be connected for rolling bearing between main shaft and the cylinder body.Hole jackscrew on U type clevis 14 both sides on the cylindrical of escapement 8 is fixed with bearing pin 17, one end socket of the middle part of bearing pin 17 and connecting rod, the other end of connecting rod and piston socket, piston is positioned at the steel bushing (as shown in Figure 1) on the cylinder body 18,19, the axis of steel bushing and the parallel axes of main shaft, connecting body 20 upper inner are provided with the slideway 23(that is complementary with guide rod 7 as shown in Figure 1, 2).Also bolt has gas lid 24,25 in the both sides of cylinder body 18,19, with respect to each cylinder liner be respectively equipped with into, the valve door, the air intake valve place is provided with air filter, and all air intake valve all communicates in suction port, and all drain tap all communicates in relief opening and gets final product.One termination of main shaft is fixed with fans, and another termination key is connected with coupling (as shown in Figure 1).When motor or other dynamic power machine drive main shaft and rotate by coupling, the swash plate that is fixed on the main shaft drives escapement 8 motions by thrust-bearing, make of the shaft axis longitudinal oscillation of escapement 8 outer rims along main shaft 1, because the effect escapement 8 of guide rod 7 can only swing, and can not rotate, because the swing of escapement, can drive piston to-and-fro motion in cylinder sleeve by connecting rod, and go into gas by the air inlet and exhaust valve door-inhale that the gas that is connected with cylinder sleeve covers, discharge gas again, reach the purpose of air compression.

The utility model is not only limited to above-mentioned mode of execution, and any possible mode all belongs to basic thought of the present utility model.
