Embodiment
One of core of the present invention is to provide a kind of bent axle, so that the generalization degree of bent axle can be made to improve, thus in the lower-cost situation of production and administration, meets the requirement of rotor for suit of different heights.
Another core of the present invention is also to provide a kind of rotary compressor with above-mentioned bent axle.
A core more of the present invention is also to provide a kind of temperature equipment with above-mentioned rotary compressor.
In order to make those skilled in the art person understand the present invention program better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Please refer to Fig. 2, the bent axle that Fig. 2 provides for the embodiment of the present invention coordinates schematic diagram with the suit of rotor.
The bent axle that the embodiment of the present invention provides, application within the compressor, it is telescopic end 2 that bent axle is used for being set with the rotor of motor the one end be connected, as shown in Figure 2, this telescopic end 2 specifically comprises stationary axle 21 and movable sheath 22, and wherein movable sheath 22 coordinates with the end of stationary axle 21, and movable sheath 22 can moving axially along stationary axle 21, change the length of the telescopic end 2 of bent axle with this, thus adapt to the requirement of compressor drum for suit of different heights.
Achieved the change of the telescopic end length of bent axle by the cooperation of stationary axle 21 and movable sheath 22, thus make bent axle can be adaptive with the compressor drum of different heights.Which achieves by a kind of bent axle of specification and the compressor drum of multiple different heights with the use of, the versatility of bent axle improves greatly.In actual production process, without the need to making the die crank of plurality of specifications, also without the need to producing the bent axle of different lengths specification, thus effectively reduce the difficulty of the production and administration aspect of bent axle, and reduce the production and administration cost of compressor.
Provide multiple different scheme in embodiments of the present invention to realize the length change of the telescopic end of bent axle, please refer to Fig. 3, in one embodiment, the end of stationary axle 21 is for being provided with externally threaded threaded joints 211, be provided with internal thread in the endoporus of movable sheath 22, movable sheath is threaded with threaded joints 211.Movable sheath 22 can be made to advance or retreat by rotating and reverse movable sheath 22, thus change the length that overlaps of movable sheath 22 and threaded joints 211, and finally make the length of telescopic end 2 change, to adapt to the cover reload request of the rotor 1 of compressor.Certainly, the diameter of threaded joints 211 should be less than the diameter of stationary axle 21, and after movable sheath 22 is sleeved on threaded joints 211, the external diameter of movable sheath 22 is identical with the external diameter of stationary axle 21.
Please refer to Fig. 4, in another embodiment, the end of stationary axle 21 is pin joint portion 212, pin joint portion 212 offers multiple first pin-and-hole 2121, and the axis of multiple first pin-and-hole 2121 parallels, the first pin-and-hole 2121 in Fig. 4 is 4, and the axis of these 4 the first pin-and-holes 2121 is along the axial translation of stationary axle 21; Movable sheath 22 is set in pin joint portion 212, and movable sheath 22 is at least provided with a pair the second pin-and-hole for coordinating with the first pin-and-hole 2121, through the bearing pin 2122 of the first pin-and-hole 2121 and the second pin-and-hole by stationary axle 21 and movable sheath 22 pin joint.
Be not difficult to find, make corresponding the first different pin-and-hole 2121 of the second pin-and-hole can realize the length change of the telescopic end 2 of bent axle.Certainly, the diameter in pin joint portion 212 should be less than the diameter of stationary axle 21, and after movable sheath 22 is sleeved in pin joint portion 212, the external diameter of movable sheath 22 is identical with the external diameter of stationary axle 21.
In addition, the mode that a kind of key connects is also disclosed in the embodiment of the present invention, as shown in Figure 5, in the present embodiment, the end of stationary axle 21 is belled part 213, belled part 213 offers a keyway, this keyway is a lower counterbore, the bottom surface of keyway is the ladder surface 2131 that the degree of depth is different, as shown in Figure 5, the connecting key be embedded in keyway is specially wedge key 2132, and movable sheath 22 is provided with sphenoid surface for the position of matching with wedge key 2132, movable sheath 22 is inserted in belled part 213, and is connected with stationary axle 21 by wedge key 2132.
Understandablely be, when wedge key 2132 is placed on different ladders, movable sheath cover 22 enters difference to the degree of depth in wedge key 2132, for in Fig. 5, when wedge key 2132 is placed on highly maximum ladder, the degree of depth that movable sheath 22 is inserted in wedge key 2132 is the most shallow, now the length of telescopic end 2 also just becomes the longest, when wedge key 2132 is placed on highly minimum ladder, the degree of depth that movable sheath 22 is inserted in wedge key 2132 is maximum, and now the length of telescopic end 2 also just becomes minimum.Therefore this kind of fit system also can realize the change of the length of the telescopic end 2 of bent axle.
In addition, those skilled in the art can also adopt other modes to realize the change of telescopic end length, will not enumerate in the present invention to this.This kind of bent axle effectively improves the versatility of bent axle itself, a kind of bent axle of specification goes for the compressor drum of multiple different heights by the change of telescopic end length, this not only lowers the fabricating cost of bent axle, also make manufacturing enterprise facilitate the management of bent axle, the situation avoiding bent axle and rotor mispairing occurs.
Also disclose a kind of rotary compressor in the present invention, the bent axle that this rotary compressor comprises rotor and is connected with rotor, and this bent axle is bent axle disclosed in above-mentioned any embodiment.
Owing to have employed above-mentioned bent axle, thus this rotary compressor has the corresponding technological merit of above-mentioned bent axle concurrently, no longer repeats in the present invention to this.
Meanwhile, also disclose a kind of temperature equipment in the present invention, this temperature equipment includes but not limited to air-conditioning and refrigerator, and temperature equipment comprises rotary compressor, and this rotary compressor is rotary compressor disclosed in above-described embodiment.Because temperature equipment includes above-mentioned rotary compressor, thus this temperature equipment also should have the technological merit identical with above-mentioned bent axle, repeats no more equally in this present invention.
Above bent axle provided by the present invention, rotary compressor and temperature equipment are described in detail.Apply specific case herein to set forth principle of the present invention and mode of execution, the explanation of above embodiment just understands method of the present invention and core concept thereof for helping.It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also carry out some improvement and modification to the present invention, these improve and modify and also fall in the protection domain of the claims in the present invention.
