Description
Technical field
The utility model relates to a kind of scroll air compressor, is specifically related to a kind of partition ring structure of scroll air compressor.
Background technique
Scroll air compressor is high with its efficiency, noise is low, volume is little, be conducive to the advantages such as energy-conservation and protection of the environment and be widely used in the compressed-air actuated occasions of industry needs such as industry, agricultural, communications and transportation.Scroll air compressor mainly moves part whirlpool dish and only has engagement, do not produce wearing and tearing, thereby the life-span is longer than piston type, screw compressor, is pneumatic machinery ideal power source.In scroll air compressor, main operation part whirlpool dish is divided into Moving plate and quiet dish, in Moving plate and quiet dish, establish vortex sheet, conventionally, by Moving plate and quiet dish, be bonded to each other and form compression chamber, when Moving plate is done translation by bent axle drive along certain circular path, Moving plate vortex sheet moves relative to quiet dish vortex sheet, by both formed compression chambers, move and change its volume, thereby sucking, compress, discharge, completing compressed-air actuated process.
Tradition scroll compressor adopts in partition ring (being also euclidean Ring) maintenance Moving plate movement process and quiet dish constant phase difference all the time.Fig. 6 is the graphics of prior art partition ring, and this partition ring respectively has two outstanding cuboid keys in two directions perpendicular to annulus end face, and the bi-side of cuboid coordinate with Moving plate keyway and forebay keyway, and motion mode is for slidably reciprocating.This sliding movement mode; during motion, frictional force is larger; slip resistance is larger; in scroll compressor startup, shutdown and high-speed motion process; easily occur wearing and tearing, along with the increase of running time, these wearing and tearing are irreversible; finally can cause sliding movement mode to lose efficacy, thereby cause the consequence of the stuck and compressor failure of compressor.
Model utility content
The purpose of this utility model is to provide the scroll air compressor that a kind of drive manner of partition ring is rolling type, reduces motion wearing and tearing, improves the stability of scroll air compressor work.
The scroll air compressor of the disclosed this partition ring rolling motion of the utility model, comprise quiet dish, Moving plate, bent axle, partition ring, forebay and rear bay, quiet dish, forebay and rear bay are connected successively, Moving plate is positioned on forebay by partition ring angle, the wheel hub of Moving plate stretches in forebay, in the wheel hub of the eccentric segment insertion Moving plate of bent axle, by bearing, connect, the non-eccentricity section of bent axle is positioned at forebay and is connected the rear axial centre that forms inner chamber with rear bay, is connected respectively by main bearing with supplementary bearing; Bent axle drives Moving plate rotation and quiet dish engagement to form air compressing chamber, and two directions perpendicular to annulus end face on partition ring respectively have two outstanding connecting keys, and they are connected by keyway respectively with between Moving plate end plate and the cylindrical part of forebay.Described connecting key is cylindrical body, and its outer wall is connected with rolling element, and the outer wall of rolling element is done rolling friction campaign in the keyway on Moving plate end plate and forebay respectively.
Described rolling element is deep groove ball bearing or cylindrical rolling cover.
Described cylindrical body comprises two sections, and wherein this section of diameter by partition ring end face is greater than another section, and it is upper that described rolling element is connected in this section that diameter is little, and enlarged diameter section makes rolling element axial limiting to avoid the partition ring end face that weares and teares.
Between the cylindrical part of described forebay and housing, offer annular groove, on annular groove, offer for connecting the keyway of described rolling element.
Connecting key on the utility model partition ring end face is set to cylindrical structure, and rolling element is installed on cylindrical body, rolling motion in the keyway of rolling element in Moving plate end plate and forebay cylindrical part, friction is each other rolling friction, friction factor reduces greatly compared with the sliding friction of prior art, thereby greatly reduce the wear extent of Moving plate and forebay cylindrical part connecting key groove location, scroll compressor can be turned round with higher rotational speed, so not only having improved compressor is starting, reliability when shutting down and running up, effectively avoid scroll compressor starting, shut down and run up in occur that partition ring running lost efficacy, the serious consequence that causes compressor operation running to be lost efficacy, and can make less scroll compression machine host meet the running speed of requirements at the higher level, reduce the weight of compressor, thereby reduce the input cost of scroll compressor.

Embodiment
Embodiment one, as shown in Figures 1 to 5, the scroll air compressor of the disclosed this partition ring rolling motion of the utility model, comprises quiet dish 1, Moving plate 2, partition ring 3, bent axle 4, forebay 5, main equilibrium block 6, rear bay 7, rear case component 8, secondary equilibrium block 9, bearing 15, main bearing 16, supplementary bearing 17.Quiet dish 1, forebay 5 and rear bay 7 are connected successively, on quiet dish 1, there is intakeport 11, Moving plate 2 is positioned on forebay 5 by partition ring 3 angles, the central part of forebay 5 housing 5-2 front ends is provided with cylindrical part 5-1, between the housing 5-2 of cylindrical part 5-1 and forebay 5, offer annular groove 5-3, at the front end of cylindrical part 5-1, establish annular support collar with axially support Moving plate 2.The wheel hub of Moving plate 2 stretches in cylindrical part 5-1, in the wheel hub of the eccentric segment insertion Moving plate 2 of bent axle 4, by bearing 15, connect, the non-eccentricity section of bent axle 4 is positioned at forebay 5 and is connected the rear axial centre that forms inner chamber with rear bay 7, is connected respectively by main bearing 16 with supplementary bearing 17.
The wheel hub of Moving plate 2 is done around circular translational under the driving of bent axle 4 eccentric parts in this cylindrical part 5-1, and Moving plate 2 forms air compressing chamber with quiet dish 1 engagement.
Two directions perpendicular to annulus end face on partition ring 3 respectively have two outstanding connecting key 3-1, and connecting key 3-1 is cylindrical body, and its outer wall is connected with rolling element 3-2.On the end plate of annular groove 5-3 and Moving plate 2, all offer for being connected the keyway of rolling element 3-2, the outer wall of rolling element 3-2 is done rolling friction campaign respectively in the end plate of Moving plate 2 and the keyway on forebay 5.
The rolling element of the present embodiment adopts deep groove ball bearing, and partition ring 3, connecting key 3-1 and rolling element 3 deep groove ball bearings form partition ring assembly, and partition ring assembly keeps the phase difference between Moving plate 2 and quiet dish 1.
