Description
The utility model belongs to refrigeration technology field, relates to the improvement to the improvement Stirling cycle refrigerator.
United States Patent (USP) 3074244 disclosed improvement Stirling cycle refrigerators have bigger superiority than other refrigeration systems.For cryogenic refrigeration machinery, it than other cryogenic systems in light weight, cost is low, efficient is high, nuisanceless.It has been used for military fields such as infrared acquisition, night vision.But this so far refrigerating machine does not enter commercialization and domestic environments as yet.Its reason is commercial and family expenses need the higher ratio of performance to price, that is refrigerating efficiency, and the while reliability will be higher and cost is low.After No. 3074244 patents, also have patent applications of some relevant improvement Stirling cycle refrigerators, US4282716 for example, US4375749, US4550571, US3698182, US4796430 etc.Disclosed various improvement Stirling cycle refrigerator scheme has a common shortcoming, has promptly continued to use traditional driving mechanism pattern, CD-ROM drive motor by shaft coupling through the gear graduation transmission.This pattern has reduced transmission efficiency, simultaneously also owing to there being a plurality of transmission links to cause the reliability decrease of complete machine.
The purpose of this utility model is the shortcoming that overcomes above-mentioned improvement Stirling cycle refrigerator, and a kind of motor rotor is provided--the driving mechanism of the incorporate improvement Stirling cycle refrigerator of bent axle, simplify transmission link, and reduce power transmission loss, raise the efficiency and reliability.
The technical solution of the utility model is: a kind of driving mechanism of improveing Stirling cycle refrigerator, the blind flange 11a and the 11b that comprise a cylinder block 1 and blanket gas cylinder body 1, a compression cylinder 3 is arranged on the cylinder block 1, the piston 2 that band connecting rod 4a is wherein arranged, also has an expansion cylinder 7 on the cylinder block 1, the piston 6 that band connecting rod 4b is wherein arranged, it is characterized in that, CD-ROM drive motor is directly installed in the cylinder block 1, motor stator 8 directly embeds in the installing hole 17 at cylinder block 1 middle part, the central shaft 10 of motor rotor 9 by about each bearing 16 and about each bearing (ball) cover 5 with the cylinder block 1 that is embedded with motor stator 8, constitute a complete CD-ROM drive motor, respectively there is a crank at the two ends of central shaft 10, promptly 14 and 15, crank 14 connects with the connecting rod 4a that is connected compression piston 2 by bearing, and crank 15 connects with the connecting rod 4b that is connected expansion piston 6 by bearing.
The utility model has the advantages that CD-ROM drive motor is installed in the cylinder block, and motor rotor axle and bent axle are all one, have fundamentally simplified transmission link, thereby have improved transmission efficiency, have reduced manufacturing cost.Simultaneously, because the simplification of structure and cylinder block are installed reducing of faying face, the reliability of sealing and complete machine is greatly improved, and then machine performance price ratio is improved.
Description of drawings, Fig. 1 are the utility model structural representations.
Below in conjunction with accompanying drawing the utility model is described in further details.Referring to Fig. 1, cylinder block 1 has compression cylinder 3 and expansion cylinder 7 by high-strength aluminum alloy or spheroidal graphite cast-iron manufacturing on it, and the compression piston 2 of band connecting rod 4a is arranged in the compression cylinder 3, and the expansion piston 6 of band connecting rod 4b is arranged in the expansion cylinder 7.The top of cylinder block 1 is cold head.The method of operation and US3074244 patent disclosure identical that has the refrigeration machine of the utility model driving mechanism.Characteristics of the present utility model are CD-ROM drive motor is directly installed in the cylinder block 1, and cylinder block 1 becomes the housing of CD-ROM drive motor, and the armature spindle of CD-ROM drive motor has the function of bent axle simultaneously again.In cylinder block 1, there is a two ends symmetry below of compression cylinder 3 and expansion cylinder 7, three stepped holes that progressively increased to the two ends diameter by inside center.The central diameter minimum be motor stator installing hole 17, motor stator 8 cooperates by tightness and is embedded in the hole 17.Each is fixing a bearing (ball) cover 5 in the stepped hole at installing hole 17 two ends, and its central authorities are bearing blocks.The effect of bearing (ball) cover 5 is supporting motor rotors.The length to diameter ratio of motor rotor 9 is between 1.7～2.0.Its central shaft (10) is bent axle just.At the two ends of central shaft 10 crank is arranged respectively, promptly 14 and 15.Central shaft 10 is connected with two bearing (ball) covers 5 by two bearings 16.Motor rotor 9 by 5 supportings of two bearing (ball) covers is concentric with stator 8.The eccentric throw of the crank 14 of central shaft 10 1 ends requires to determine according to the stroke of compression piston 2.The eccentric throw of the crank 15 of central shaft 10 other ends requires to determine according to the stroke of expansion piston 6.When motor rotor rotated, central shaft 10 made driving-chain reduce to minimum by crank 14,15 and direct driven plunger 2,6 motions of connecting rod 4a, 4b.Have a rotatable phase poor between the crank 14 and 15, its phase angle is 90 ° ± 3 °.Each is sealed the two ends of cylinder block 1 by a high-strength aluminum alloy blind flange 11a and 11b, and the heat radiation wing is arranged on the blind flange.Motor can adopt and exchange or direct current generator.
A design of finishing by embodiment shown in Figure 1 shows, design adopts driving mechanism of the present utility model to compare with the through engineering approaches model machine of the commercial improvement of certain type Stirling cycle refrigerator of a same refrigerating capacity, machine part can reduce to 55 kinds, minimizing 16% from 66 kinds; The main transmission bearing is reduced to 2 from 4; Aluminum alloy materials can reduce 40%.
