Abstract
The utility model discloses a swash plate for compressors, which comprises a swash seat and an outer ring of the swash; wherein, the swash seat is provided with a driving draft central hole; a hole for accommodating the swash seat is arranged in the middle of the outer ring of the swash plate. The swash seat is sleeved in the accommodating role on the outer ring. The swash seat and the swash outer ring are riveted through a rivet. The utility model has the advantages that the swash seat and the outer ring of the swash plate are more solidly riveted through the rivet, avoiding the possible loosing problem caused by thread coupling. The utility model also plays a fixing role to the relative position of the swash seat and the outer ring of the swash plate through the rivet and reduces the requirement for coordinating precision between the swash seat and the outer ring of the swash plate. The utility model also overcomes the shortcomings of separate design and low universality of compressors during forward and reverse rotations.
Description
Technical field
The utility model relates to the parts of the compressor of vehicle air conditioning, more specifically refers to a kind of rotation swash plate of compressor.
Background technique
In the variable displacement rotary slope plate type compressor, the rotation swash plate comprises swash plate seat and swash plate outer ring.Swash plate seat and swash plate outer ring are by being threaded.The swash plate seat is installed on the drive main spindle, and connects by guiding device with the driven compressor dish, realizes that the inclination angle of rotation swash plate self changes.The swash plate outer ring links to each other by crawler shoe with piston in the compressor.Thereby rotation and crawler shoe by swash plate slide, and realize the to-and-fro motion of piston in casing bore, reach air-breathing, the exhaust process of compressor.It is worthy of note: the slide member of compressor inner structure lubricated is contained in normally that lubricant oil in the compressor forms mist of oil with circuit refrigerant gas in the running compressor and takes the lubricant oil of mist of oil form to each sliding parts and carry out.Yet, swash plate outer ring and crawler shoe begin to slide before lubricant oil arrives its slidingsurface after compressor just starts, and before the slidingsurface between lubricant oil arrival swash plate outer ring and the crawler shoe, gaseous refrigerant arrives slidingsurface and washes the lubricant oil that is trapped on the slidingsurface.Therefore, after just starting compressor, swash plate outer ring and crawler shoe are not have mutual slip the under the dryness sliding condition of lubricant oil.Turn back to compressor and compressor starts at refrigerant gas and form in time period (about 1 minute) between the mist of oil form, the sliding parts that needs to lubricate under compressor is in lubricating status is in a kind of inadequate lubricating status.Even in order to ensure MIN the lubricating of supplying with at oiling agent under the insufficient situation, the matrix of aluminium or iron-based is generally adopted in the swash plate outer ring now, and the part that contacts crawler shoe is applied various solid lubricants.The shortcoming of this method is: the solid lubricant of coating also will have wear-resisting characteristic simultaneously, and this has increased selects the difficulty of cladding material and often need higher, complicated coating processing technology.Like this, the processing speed that slowed down has increased manufacture cost, and is especially unfavorable to producing in batches.Simultaneously, the rotation swash plate comprises swash plate seat 7 and swash plate outer ring 8, swash plate seat 7 offers shaft center hole 71, the bottom of swash plate seat 7 offers outside thread, the middle part of swash plate outer ring 8 offers the receiving hole 81 of ccontaining swash plate seat 7 bottoms, be provided with in the through hole 81 can with the internal thread of swash plate seat 7 outside thread bolts, swash plate seat 7 and swash plate outer ring 8 is by screw thread bolt (see figure 1), both quality of fits are had relatively high expectations; Need design respectively during the compressor forward and reverse, versatility is poor.And the work of rotation swash plate the time is in high speed rotating and is accompanied by the inclination angle and change, and may produce situations such as moving back pine, causes compressor damage.
Summary of the invention
The purpose of this utility model is the shortcoming that exists at the tradition in compressor rotation swash plate, and the rotation swash plate of a kind of sound construction, technology is easy, cost is low compressor is provided.
To achieve these goals, the utility model adopts following technological scheme: the rotation swash plate of this compressor comprises swash plate seat and swash plate outer ring, the swash plate seat offers the shaft center hole, the middle part of swash plate outer ring offers the receiving hole of ccontaining swash plate seat, the swash plate cover for seat places in the receiving hole of swash plate outer ring, rivets mutually by rivet between swash plate seat and the swash plate outer ring.
The center hole side of described swash plate seat is offered connecting through hole, and the side of the receiving hole of swash plate outer ring and also offer connecting through hole in swash plate seat connecting through hole opposite position place wears rivet and riveted joint in the connecting through hole of swash plate seat and swash plate outer ring.
This rotation swash plate further comprises pressing plate, pressing plate places below the swash plate outer ring, offer the center hole that communicates with swash plate outer ring receiving hole on the pressing plate, center hole side and offer attachment hole with the connecting through hole corresponding position of swash plate outer ring wears rivet and riveted joint in the connecting through hole of the connecting through hole of swash plate seat, swash plate outer ring, the attachment hole of pressing plate.
In technique scheme of the present utility model, the rotation swash plate swash plate seat and swash plate outer ring connect by rivet, make that both connections are more firm, it effectively prevented scyewed joint may move back the pine problem; And, by rivet the relative position of swash plate seat and swash plate outer ring is played fixation, reduced the quality of fit requirement of swash plate seat and swash plate outer ring; Need design respectively when also having solved the compressor forward and reverse, the shortcoming of versatility difference.
