Abstract
The multi-cylinder compressor contains the low and up coveres, eccentric shaft, N cylinderes, piston and blades. The eccentric shaft is a separated type and N eccentric parts in 360 deg. angles are fixed on the straight shaft. Between cylinders isolating sheets are set. The eccentric shaft is manufactured by machining eccentric part and straight shaft separately and then fixing the eccentric part onto the straight shaft by key, pin or tooth. The multi-cylinder compressor has less moment fluctuation, low shock and vibration, smooth operation and less noise, and may become large power or varying-frequency compressor.
Description
The present invention relates to cooling compressor, specifically refer to idle call rolling rotor-type multicylinder compressor, and the manufacture method of the eccentric shaft of this compressor.
Rolling rotor type compressor is made up of motor and compressor two large divisions, and wherein compressor section comprises upper cylinder cover, following cylinder cap, eccentric shaft, cylinder, piston, blade, and its working principle as shown in Figure 1.Establish an eccentric shaft 3 in the cylinder 1, eccentric shaft 3 peripheral hardwares one annular piston 2, this piston and cylinder inner wall are tangent, form a crescent shape chamber, one blade 4 is located in the chute of cylinder 1, this blade is under spring 5 is acting on, all the time the periphery with piston 2 contacts, described crescent shape chamber is divided into air aspiration cavity and exhaust cavity, intakeport 1-1 communicates with air aspiration cavity, and relief opening 1-2 communicates with exhaust cavity, when doing eccentric rotation under the drive of eccentric shaft 3 at motor, the motion of piston constantly changes the volume of air aspiration cavity and exhaust cavity, will be discharged by relief opening from intakeport inhaled air compression back.In theory, this compressor can be designed to the multi-cylinder structure, but because the processing of the vital part eccentric shaft 3 in the present compressor is to adopt the integral type method for processing, when number of cylinders greater than 3 the time, eccentric part in the middle of piston can't be inserted in and be positioned at during assembling, the therefore present type that also has only single cylinder and twin-tub.These types are because the torque fluctuations on the eccentric shaft is big, and therefore vibrations are also big with noise, and its discharge capacity also is restricted.
Because described eccentric shaft adopts the mode of d-axis and the processing of eccentric part one, the technical requirements height of this integral type eccentric shaft, the processing conditions harshness, to process with the very high special purpose machine tool of requirement on machining accuracy, and this lathe has only a few countries to produce at present, so the manufacturing expense height, and the manufacture cycle is long, face and be unfavorable for the exploitation of kind has also influenced the exploitation of multi-cylinder engine especially.
The objective of the invention is to propose a kind of idle call rolling rotor-type multicylinder compressor, to improve the operation stability of compressor, adapt to the high stability of air conditioner, the development trend of big discharge capacity and frequency conversionization.
Another object of the present invention is to propose a kind of new method for manufacturing accentric shaft, to simplify its manufacturing process, enhance productivity, reduce manufacturing expense, reduce production costs, accelerate new product development speed, improve the complete machine performance, and the assembling piston that can solve multicylinder compressor can't a difficult problem, the exploitation multicylinder compressor.Improvement by to the manufacture method of compressor eccentric shaft proposes the design of cooling rolling rotor-type multicylinder compressor, to increase compressor displacement, improves compressor performance.
Idle call rolling rotor-type multicylinder compressor of the present invention, form by motor and compressor two large divisions, wherein compressor section comprises upper cylinder cover, following cylinder cap, eccentric shaft, cylinder, piston, blade, it is characterized in that described number of cylinders is N (N 〉=1), described eccentric shaft is a d-axis that has N eccentric part, a described N eccentric part becomes 360 °/N angle serial arrangement corresponding to the position of N cylinder, is fixed on the main shaft by key or pin, tooth.When number of cylinders N 〉=2, between per two cylinders, be provided with dividing plate.
Method for manufacturing accentric shaft of the present invention is: at first with the eccentric part of eccentric shaft and the processing respectively of d-axis part, the mode by key or pin, tooth is assemblied in eccentric part on the d-axis then, becomes an one-piece rotor shaft.
The advantage of rolling rotor-type multicylinder compressor of the present invention can reduce the torque fluctuations of eccentric shaft, reduces and impacts and vibrations, and the steady noiseless that turns round can be used for high-power or inverter controlled rotary compressor.
The advantage of the manufacture method of eccentric shaft of the present invention is, can simplify the manufacturing process of eccentric shaft, improves the efficiency of assembling of the production of eccentric shaft, reduces manufacturing expense, accelerates new product development speed; Because d-axis separate processing with eccentric part, so eccentric part can adopt lightweight material different with d-axis or the making of other quality material, with the minimizing mechanical loss, improves the friction situation, the raising product reliability; Simultaneously, because new split type eccentric shaft has solved the piston assembly problem of multicylinder compressor, for road has been paved in the design of multi-cylinder engine.
The invention will be further described in conjunction with an embodiment and accompanying drawing.
Fig. 1 is a rolling rotor type compressor working principle schematic representation;
Fig. 2 is the structural representation of idle call rolling rotor-type 3 cylinder compressors of the present invention;
With rolling rotor-type 3 cylinder compressors is example, this compressor is divided into motor and compressor two large divisions, all be enclosed in the housing 6 of a sealing, wherein the motor section branch comprises stator 7 and rotor 8, and compressor section comprises upper cylinder cover 9, following cylinder cap 10, eccentric shaft 3, cylinder 1, piston 2, blade 4; Described cylinder has 3, between per two cylinders, be provided with dividing plate 11, upper cylinder cover, following cylinder cap, 2 dividing plates make 3 cylinders separate, eccentric shaft is a d-axis that has 3 eccentric parts, the position of these 3 eccentric parts is corresponding with the position of 3 cylinders, and is in 120 ° and is arranged above and below and is fixed on the main shaft by key, and each eccentric part drives a piston and does eccentric rotation, finish the workpiece of pressurized gas, referring to Fig. 2.Each cylinder is equipped with intakeport and relief opening, and total sucking pipe leads to outside the housing, and communicates with the intakeport of each cylinder, and the exhaust ports of each cylinder is provided with drain tap, and the gas of discharge is derived by total air escape pipe 12.
Owing to adopted split type eccentric shaft, it is easy that the multi-cylinder engine that can't assemble is originally become.Its assembly process is as follows: earlier first eccentric part is keyed on the d-axis, first piston is installed, cover first dividing plate; Then second eccentric part is fixed on the d-axis with keyboard, second piston is installed, cover second partition; At last the 3rd eccentric part is fixed on the d-axis with keyboard, the 3rd piston is installed.
The manufacture method of eccentric shaft of the present invention is:
1. the d-axis part of eccentric shaft is processed respectively according to technical requirements with eccentric part;
2. by key or pin, tooth eccentric part is assemblied on the d-axis, makes into as a whole eccentric shaft.
