Fig. 2 is the sectional drawing of multi-stage variable speed composite rotary compressor of the present invention.
Embodiment
Be elaborated below in conjunction with the concrete structure of accompanying drawing to multi-stage variable speed composite rotary compressor of the present invention.
As shown in Figure 2, multi-stage variable speed composite rotary compressor of the present invention comprises: airtight housing, be arranged on the top of housing, the motor driving part of forming by rotor and stator 40, be arranged on the press part 60 of lower housing portion, described press part 60 comprises upper bearing (metal) 62, lower bearing 65 and be arranged on upper bearing (metal) 62 and lower bearing 65 between cylinder and roll ring, the following running shaft 61 that the running shaft of described compressor is arranged on the last running shaft 42 in the rotor by insertion and runs through compressor section 60 is formed, and is provided with the gear of the output speed that is used to change motor on described between running shaft 42 and the following running shaft 61.
As shown in the figure, described gear is a speed-change gear box, and it comprises: the driving gear 51 of fixedlying connected with described upward running shaft 42; Be installed on the jack shaft 56 also by the 1st driven tooth wheels of main driven gear 52 with driving gear 51 engagements; The 2nd driven tooth wheels 56 that are installed in down at interval on the running shaft 61 and mesh respectively with gear in the described driven tooth wheels, driven gear in described the 2nd driven tooth wheels optionally combines with following running shaft 61, thereby the rotating force of motor is passed to down running shaft 61.
The 1st driven tooth wheels and the 2nd driven gear group are made up of a plurality of gears respectively, and in the present embodiment, the 1st driven tooth wheels are made up of the driven gear 53,54,55 that main driven gear 52 and a plurality of interval are provided with, differ in size.Similarly, the 2nd driven tooth wheels 56 also are made up of the driven gear that a plurality of intervals are provided with, differ in size.Driven gear in the 2nd driven tooth wheels 56 optionally combines with following running shaft 61 by the key (not shown).This point can be finished by control mechanism, for example: receive temperature signal by temperature transducer, and then control corresponding driven gear and combine with lower bearing.
In addition, in order to keep the balance of gear-box, equilibrium block 57 is installed in the outside of the gear-box relative with the 1st, the 2nd driven tooth wheels.
When compressor operating of the present invention, can be according to the output speed of the needs of refrigerating capacity being regulated motor, for example, when temperature is low, the bigger gear of diameter in the 2nd driven tooth wheels 56 with the gear engagement of the 1st driven tooth wheels is combined with lower bearing 61, make the lower rotating speed of its output.Otherwise when the bigger refrigerating capacity of needs, under the effect of control mechanism, the gear less with the diameter in the 2nd driven tooth wheels 56 of the gear engagement of the 1st driven tooth wheels combines with lower bearing 61, thus the output high rotational speed.That is: can be under the effect of control mechanism according to the output speed of the different self-regulation motors of refrigerating capacity/temperature, thus reach purpose of energy saving.
