Abstract
The utility model discloses a balance weight of a piston compressor. The balance weight comprises an arc portion and a rectangular portion, the center of circle of the arc portion corresponds to the center of circle of an eccentric portion of a crankshaft and is provided with a through hole connected with the crankshaft, and the size of the rectangular portion is designed according to the fact that eccentricity of a combination of the crankshaft and a piston can be balanced by the center of mass of the balance weight. The balance weight has the advantages that the balance weight is simple in processing, capable of saving materials and guaranteeing vibration of the complete compressor, overcomes inclined vibration of the compressor, and solves the problem of vibration of the compressor due to abrupt acceleration or deceleration on application occasions.
Description
Technical field
The utility model relates to a kind of equilibrium block of piston compressor.
Background technique
In the prior art as shown in Figure 1, piston 4 is connected with connecting rod 2 by pin 5, and piston compressor is when proper functioning, and 3 rotations of motoring bent axle are carried out straight reciprocating motion by connecting rod 2 drivings.In this process, owing to have unbalanced force and moment, the pump housing can vibrate with respect to rotating center.Therefore need increase some equilibrium blocks 1 on bent axle 3 eliminates this vibration.
Especially for the compressor on being applied in car, since in the vehicle driving process for the requirement that reduces the car body noise, therefore the vibration of compressor is required very strict, and in technology now, equilibrium block shape commonly used is generally semicircle, by the interference mount on the bent axle minor axis.But the shortcoming of the equilibrium block of this shape is, though it can guarantee the complete machine oscillation level of compressor, but the vibration of diagram Y direction is bigger, and therefore can not satisfy this vehicle-mounted compressor has the requirement of lateral tilt angular vibration, thereby needs a kind of new equilibrium block of design to eliminate the vibration of compressor.
The model utility content
Task of the present invention is by designing a kind of equilibrium block of new compressor, reducing the vibration of complete machine, thereby realizes the erasure effect of expectation.
The present invention realizes above-mentioned task by following design: equilibrium block comprises curved portions and rectangular portion, the center of circle of curved portions is corresponding to the rotating center of bent axle, and curved portions is provided with the through hole that is connected with bent axle, it is characterized in that being dimensioned to of described rectangular portion makes that the barycenter of equilibrium block can balance crankshaft and the off-centre of piston in combination.This kind profile has reduced the consumption of equilibrium block material under the prerequisite that guarantees the vibration of compressor level.
Preferably, described equilibrium block is installed in the end of crank, with equalizing piston for moment that bent axle was produced.
Preferably, the thickness of described equilibrium block is between 1mm-5mm.
Preferably, described equilibrium block forms through hole in its rectangular portion.
Preferably, described through hole is about the center line symmetry of rectangular portion.
For vehicle-mounted compressor, use semicircle equilibrium block therefore new equilibrium block require under the prerequisite of the vibration level of the machine complete machine that guarantees to contract, reduce as far as possible Y to vibration, the vibration problem when improving compressor greatly and tilting.Square equilibrium block has just solved this difficult problem, not only can guarantee the vibration of complete machine, has also improved the tilt and vibration problem of compressor, has solved the vibration problem when compressor is subjected to acceleration suddenly or deceleration in the application.
Description of drawings
Hereinafter with reference to accompanying drawing and in conjunction with the preferred embodiments of the present invention the present invention is described in further detail, wherein:
Fig. 1 has shown the schematic representation of the equilibrium block of prior art;
Fig. 2 has shown the plan view of the equilibrium block of prior art;
Fig. 3 has shown the schematic representation according to equilibrium block of the present invention; With
Fig. 4 has shown the plan view according to equilibrium block of the present invention.
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
As shown in Figure 3, bent axle 3 is connected to motor by known way.One end of connecting rod 2 is enclosed within on the bent axle 3, and the other end is connected with piston 4 by pin 5.
As can be seen from the figure, equilibrium block 6 according to the present invention comprises curved portions 8 and rectangular portion 9.The center of circle of curved portions 8 is corresponding with the center of circle of bent axle 3 eccentric parts.Simultaneously, curved portions is processed with through hole, so that equilibrium block 6 is installed in the end of bent axle 3.Being dimensioned to of described rectangular portion makes that the barycenter of equilibrium block can balance crankshaft and the off-centre of piston in combination.
In selectivity embodiment, equilibrium block 6 is installed in the end of bent axle 3, and the thickness of equilibrium block 6 is between 0.5mm-5mm.Alternatively, equilibrium block 6 can form through hole in its rectangular portion, and with economical with materials and adjust barycenter, wherein said through hole is about the center line symmetry of rectangular portion.
Below embodiment has been described in detail the utility model in conjunction with the accompanying drawings, but should be understood to above-mentioned explanation is not for qualification of the present utility model, under the prerequisite that does not deviate from spirit and scope of the present utility model, those skilled in the art can make amendment to the utility model.
Claims (5)
1. the equilibrium block of a piston compressor, comprise curved portions and rectangular portion, the center of circle of curved portions is corresponding to the rotating center of bent axle, and curved portions is provided with the through hole that is connected with bent axle, it is characterized in that the barycenter that is dimensioned to equilibrium block of described rectangular portion and the off-centre of bent axle and piston in combination balance each other.
