Description
(1) technical field: the present invention relates to chiller plant, is a kind of curve-driven reciprocating piston type refrigerating compressor.
(2) background technique: compressor is the heart component of chiller plant, up to now, its piston drive mode of Totally-enclosed piston type compressor of generally using in traditional chiller plant industry is (referring to Fig. 1) by motor rotating band dynamic pressure machine crankshaft 20 rotations of contracting, bent axle 20 is changed into transverse reciprocating motion power by eccentric shaft 21 with the axial rotating force that motor produces, pass to piston 22 by connecting rod 23, piston 22 is moved back and forth, this kind structure becomes transverse reciprocating motion power because of the axial rotating force that motor produces by bent axle, compressor this transverse reciprocating motion power when operation can make compressor lose dynamic balancing, causes vibration of compressor, noise is bigger.Also must increase unit volume as the compressor that needs to make bigger refrigerating capacity simultaneously, make big refrigerating capacity compressor volume increase.
(3) summary of the invention: the piston compressor to-and-fro motion force unbalance that the objective of the invention is to overcome transmission, vibration of compressor, the problem that noise is big, improve the compressor specific refrigerating effect simultaneously, a kind of new curve-driven reciprocating piston type refrigerating compressor is provided.
Design proposal of the present invention is: the curvilinear motion reciprocating-piston type refrigerating compressor, include casing, and motor is housed in the casing, the cylinder frame that is linked and packed with motor, and piston-cylinder, it is characterized in that: the cylinder block of piston-cylinder and cylinder frame positioned opposite, and by the connection of cylinder fixed base; Between cylinder piston and motor bent axle, be connected by a sets of curves driven plunger reciprocating mechanism; This curve driven plunger reciprocating mechanism, include a piston that is connected with piston and promote a guide and an axle sleeve that is connected with the motor bent axle, have the closed annular curvilinear groove on the axle sleeve, put at the piston pushing pin and to be installed with a transmission shaft, one end of transmission shaft stretches into that guide movement connects in the curvilinear groove of axle sleeve, and is provided with and makes piston promote the guide mechanism that guide keeps straight reciprocating motion.
Make piston promote the guide mechanism that guide keeps straight reciprocating motion described in the present invention, multiple structural type can be arranged, two kinds of typical guide mechanisms are provided here, scheme one: be to make the plane vertically in the some of piston promotion guide outer side wall, relative contact with this plane is furnished with a reciprocal guide plate, and this reciprocal guide plate adopts screw to be installed in the cylinder fixed base.Scheme two: be to promote the boss that the design of guide outer wall is axially linearly arranged at piston, the guide pad of mounting strap straight-line groove in the cylinder fixed base, boss are contained in that slide-and-guide connects in the groove of guide pad.
The closed annular curvilinear groove of opening on the axle sleeve described in the present invention, launching the back on axle is the sine wave curve groove in one-period or a plurality of cycles.It can also be the curvilinear groove that to realize the to-and-fro motion conversion of other form.
Axle sleeve described in the present invention is to fixedly connected with bent axle with the axle sleeve locating stud by the location lid of compression fit, can also adopt alternate manner fixed axle sleeves such as key connecting certainly.
For reducing the transmission resistance, be fixedly mounted on the transmission shaft that the piston pushing pin puts described in the present invention, its end that stretches in the curvilinear groove of axle sleeve is equipped with bearing.Certainly the cancellation bearing also is feasible.
For refrigerating capacity is provided significantly, the present invention can also make horizontal type structure, soon motor will be horizontal is installed in the middle of the casing, the motor bent axle stretches out to two ends, and be symmetrical arranged left and right sides cylinder frame at the motor two ends, left and right sides cylinder fixed base, left and right sides piston-cylinder, and left and right sides curve driven plunger reciprocating mechanism.
The present invention is by the kind of drive structural change to compressor inside, laterally reciprocal unbalanced force is converted into less relatively the pumping of vibrating noise influence, and the effect of the stage clip by being contained in motor bottom in the existing structure, make unbalanced force few noise vibration that has influence on compressor of trying one's best; In addition, can under the situation of unit volume that does not improve compressor and motor revolution, increase exponentially compressor refrigerating capacity, thereby not increase the volume size when making compressor improve refrigerating capacity by the curvilinear groove of design multicycle sine wave on the axle sleeve.
The present invention compared with prior art has the following advantages:
1, the uneven to-and-fro motion power that compressor is in operation and produces be can effectively reduce, compressor noise, vibration reduced;
2, can under the situation of unit volume that does not improve compressor and motor revolution, increase exponentially compressor refrigerating capacity.
