Description
Technical field
The utility model belongs to compressed air unit technical field, is related to a kind of air compressor machine, in particular to a kind of cylindrical shaft
Hold the scroll air compressor for cooperating anti-Self-rotation structure with circular hole.
Background technique
Scroll air compressor is high-efficient with its, low noise, small in size, the advantages that being beneficial to energy conservation and protecting environment and it is wide
The general occasion that compressed air is needed applied to industries such as industry, agricultural, communications and transportation.Scroll air compressor mainly runs part whirlpool
It is only engaged between disk, relative velocity is low, and air inlet-exhaust valve remains stationary when movement, because without the vulnerable parts such as air inlet-exhaust valve, longevity
Life is longer than piston type, screw compressor, is pneumatic machinery ideal power source.It is main to run in scroll air compressor
Part whirlpool disk is divided into Moving plate and quiet disk, sets vortex piece in Moving plate and quiet disk, in general, being bonded to each other by Moving plate and quiet disk and being formed crescent
Compression chamber, when Moving plate is translatable by crankshaft drive along certain circular path, the quiet disk vortex piece shifting relatively of Moving plate vortex piece
It is dynamic, i.e., compression chamber movement is formed by by the two and its volume is gradually reduced, to complete the process of air-breathing, compression, exhaust.
Traditional scroll air compressor technical solution keeps the phase difference between Moving plate and quiet disk using cross slip-ring, and ten
Word slip ring both ends of the surface have two pairs of orthogonal keys respectively, and each pair of key matches with the keyway on the keyway and rack on Moving plate respectively
It closes or each pair of key is matched with the keyway on the keyway and quiet disk on Moving plate respectively.Partition ring in the running can be back and forth toward high
Speed movement, can generate additional centrifugal force in the movement direction, this centrifugal force can not balance, therefore using the vortex of this structure
The vibration of compressor is larger, can generate deleterious effect to compressor reliability of operation, the operation that also will increase compressor is made an uproar
Sound.Cross slip-ring higher cost increases the cost of compressor.Cross slip-ring is usually aluminum, and wearability is poor, works as lubrication
When oil deterioration, longer using the time than if any water entrance or lubricating oil, when there is impurity, cross slip-ring is easy to appear
Abrasion, to affect the reliability of compressor.
Summary of the invention
The purpose of this utility model is to provide a kind of cancellation cross slip-ring for the above-mentioned problems in the prior art
Structure, using being arranged cylindrical bearing on the cylinder and anti-Moving plate Self-rotation structure is realized in circular hole cooperation, it is ensured that Moving plate and quiet disk
Phase difference, to realize the scroll air compressor of rotation when anti-arresting disc is run.
The purpose of this utility model can be realized by the following technical scheme: a kind of cylindrical bearing and circular hole cooperate anti-rotation
The scroll air compressor of structure, including quiet disk, Moving plate, crankshaft, rack, main balance weight, motor, secondary balance weight and fan blade, by
Moving plate engages to form air compression chamber with quiet disk, and main balance weight is respectively arranged at the rear and front end of crankshaft with secondary balance weight, described
Crankshaft eccentric part insertion Moving plate wheel hub in, crankshaft is mounted in rack and motor with base bearing and supplementary bearing, crankshaft with
Bearing one is set between the wheel hub of Moving plate, which is characterized in that at least 2 cylindrical bodies, and cylinder are provided on the Moving plate
It is an integral structure between body and Moving plate, engagement sleeves are equipped with cylindrical bearing outside the cylindrical body, in the rack
Offer circular hole corresponding with cylinder body position, and the mutually tangent cooperation of cylindrical bearing and circular hole is to keep Moving plate and rack
Phase difference, be connected between the rack and quiet disk by positioning bolt the phase for guaranteeing position precision to guarantee Moving plate Yu quiet disk
Potential difference.
This scroll air compressor, which uses to be arranged cylindrical bearing on the cylinder and cooperate with circular hole, keeps Moving plate and quiet disk
The structure of phase difference can be solved perfectly conventionally employed cross slip-ring and keep Moving plate and quiet three masters of disk phase difference structure bring
The problem of wanting.First is that the available complete balance of Moving plate centrifugal force, and the centrifugal force generated when cross slip-ring movement can not obtain
To balance；Second is that cross slip-ring needs precise machining equipment to be processed as independent part, processing cost is high, and cross is sliding
Ring needs special surface to handle, and processing cost is high, and after structure of the invention, cylindrical body and circular hole are located at Moving plate and machine
Frame, and be structure as a whole respectively with Moving plate and rack, it is obtained by processing, does not increase the process of processing, therefore cost additionally
It can control lower；Third is that keyway of the two pairs of keys of cross slip-ring respectively with Moving plate and rack is slidably matched, the quantity of cooperation compared with
It is few, and cross slip-ring is generally aluminum, the surface hardness and intensity of aluminum material are all lower, therefore cross slip-ring is easy to happen mill
Damage and deformation, and after using the technical program, the quantity of cylindrical body and circular hole can adequately be adjusted according to stress condition, only
Design space is wanted enough can.
Further, due to being sliding friction between cylindrical body and circular hole, the contact surface of the two is prone to wear, in order to
Increase service life, cylindrical bearing is arranged outside cylindrical body, sliding friction is become into rolling friction, although manufacturing cost increases,
But contact surface abrasion speed is greatly reduced, and can satisfy the client of different demands.
In the scroll air compressor that a kind of above-mentioned cylindrical bearing and circular hole cooperate anti-Self-rotation structure, the cylindrical shaft
It holds between cylindrical body as clearance fit.
In the scroll air compressor that a kind of above-mentioned cylindrical bearing and circular hole cooperate anti-Self-rotation structure, the cylinder
The quantity of body, cylindrical bearing and circular hole is 10.
In the scroll air compressor that a kind of above-mentioned cylindrical bearing and circular hole cooperate anti-Self-rotation structure, the quiet disk
On offer the lubricating oil inlet being connected with inside it.
Compared with prior art, this scroll air compressor is by being arranged phase cut distribution of the cylindrical bearing with circular hole in cylindrical body
Resultant motion replaces traditional partition ring to have vibration, the noise, cost for reducing scroll air compressor, improves reliability,
And have the advantages that the service life is longer.
