Description
Technical field
The utility model is related to a kind of spacing swinging blower fan in slide plate root.
Background technology
Swinging blower fan is a kind of positive displacement blower fan, the permanent torque gas mechanical characteristics with forced conveyance.Its is relative simultaneously
Roots blower has higher volumetric efficiency, lower slip, lower noise.Its operation principle is the guiding in eccentric wheel
Under, produce centrifugal force（Or use spring）Drive slide plate to be close on cylinder wall to be rotated, by slide plate and eccentric wheel in cylinder body
The interior continuous volume for producing change, and realize the acting to air.Its maximum shortcoming is, during work, and slide plate is produced with cylinder body
Violent friction, seriously limits the linear velocity on slide plate top.And linear velocity is the product of radius and angular speed, it means that pass
The blade blower fan of system can not possibly both have been done in volume to be also impossible to be lifted on rotating speed greatly.So the swinging wind of market-ripe
Machine, its flow is general all within 8m3/min.Body rotating speed is no more than 500RPM.During as sliding vane rotary pump, due to there is dissipating for a full set
Hot oil return design, situation is slightly good, but rotating speed also rarely exceeds 1500RPM, and pumping speed is not also high.
For many years, in the industry, slide plate, inboard wall of cylinder block friction free swinging wind can be realized by seeking one kind always
Machine.But common scheme is realized by bent axle, multi link etc., complicated to be unfavorable for promoting, actual effect is limited.
Utility model content
In order to solve the above-mentioned technical problem, the utility model provides a kind of slide plate root spacing swinging blower fan, can be with
Inboard wall of cylinder block and the friction on slide plate top are eliminated, is realized without friction operating.
The technical solution adopted in the utility model is：A kind of spacing swinging blower fan in slide plate root, including cylinder body, turn
Son, main shaft, slide plate, isolation backing plate, oil storage backing plate, drive end bearing bracket and rear end cap, the two ends of the cylinder body are provided with isolation backing plate and storage
It is provided with the outside of lubricating pad plate, the oil storage backing plate in drive end bearing bracket and rear end cap, the cylinder body and is provided with rotor, edge on the rotor
Its length direction is provided with multiple chutes, and the chute is circumferentially uniformly distributed along rotor, and main shaft, the main shaft are provided with the rotor
Multiple slide plates are provided with, the slide plate is located in chute, a mandrel is stretched out in the root both sides of slide plate, and the mandrel is located at isolation
Moved in a circle in the endoporus of backing plate, the main shaft is fixed by the bearing at its two ends with drive end bearing bracket and rear end cap.
The slide plate is 3-6 pieces.
The beneficial effects of the utility model are：The mechanisms such as bent axle, the connecting rod of complexity have been abandoned, slide plate is fixed on using one
The mandrel of bottom, moves in a circle around dividing plate endoporus, with the tiny dots friction of mandrel and dividing plate endoporus instead of slide plate top with
The link friction of inboard wall of cylinder block, eliminates the friction of inboard wall of cylinder block and slide plate top.Staring torque is small, and complete machine disk is dynamic slim and graceful, speed governing
Performance is good, and noise is low, and low cost is simple in construction, easy to maintenance.

Embodiment
In order to deepen to understand of the present utility model, make below in conjunction with embodiment and accompanying drawing to of the present utility model into one
Step is described in detail, and the embodiment is only used for explaining the utility model, does not constitute the restriction to protection domain of the present utility model.
As shown in Figures 1 to 4, the spacing swinging blower fan in a kind of slide plate root, including cylinder body 1, rotor 2, main shaft 3, cunning
Piece 8, isolation backing plate 6, drive end bearing bracket 9 and rear end cap 5, the two ends of cylinder body 1 are equipped with isolation backing plate 6 and oil storage backing plate 4, oil storage pad
The outside of plate 4, which is provided with drive end bearing bracket 9 and rear end cap 5, cylinder body 1, is provided with rotor 2, is provided with along its length on rotor 2 multiple
Chute 10, chute 10 is uniformly distributed along rotor 2 is circumferential, and main shaft 3 is provided with rotor 2, and main shaft 3 is provided with 3-6 pieces slide plate 8（According to
Body is of different sizes, and the chute quantity opened up by rotor determines that slide plate is made up of self-lubricating material, and its surface is also provided with lubricating oil
It is 4 slide plates in groove, the present embodiment）, slide plate 8 is in chute 10, and a mandrel 11, mandrel are stretched out in the root both sides of slide plate 8
11 move in a circle in the endoporus of isolation backing plate 6, and main shaft 3 is solid by the bearing 7 and drive end bearing bracket 9 and rear end cap 5 at its two ends
It is fixed.
Isolate backing plate 6（It is made up of the hard alloy of high surface finish or other high-abrasive materials）It is connected with cylinder body, and with
The concentric arrangement of cylinder body.
During work, under the support of centrifugal force or sliding blade spring, the mandrel that slide plate root both sides are stretched out is in isolation backing plate 6
Endoporus in move in a circle, that is, isolate backing plate endoporus as mandrel raceway.
Above-mentioned mandrel size, meets following mathematical relationship：If raceway inside radius（Isolate backing plate internal bore radius）For r, cylinder body
Inside radius is R, the length L at mandrel center to slide plate top, axle diameter φ=（L+r-R）*2.
In order to avoid the presence of raceway causes compression chamber gas leakage, in general, dividing plate diameter of bore needs≤（R-2e）* 2,
(e is the eccentric throw of swinging blower fan/sliding vane rotary pump).
Because the slip of positive displacement blower fan does not change with rotation speed change, the lifting of rotating speed greatly reduces fixation
The accounting of leakage rate, is greatly improved efficiency, adds air quantity, while limit boosting can reach 150KPa.In addition, body
Grease-box and gs-oil separator are no longer needed during common utilization, complete machine structure is simplified, reduces cost.Change common return
The occupation mode of rotatable blower fan/sliding vane rotary pump, can be run with No Load Start, and without worrying to burn.
The operation principle of the blower fan：Power is inputted by main shaft, drives the rotor rotation installed with main shaft, rotor and main shaft
By the bias of front and rear cover, in cylinder body inner close fitting side, inwall rotates at a high speed, while under the drive of centrifugal force, slide plate is outside
Throw away.Due to there is the presence of slide plate root mandrel and isolation backing plate, mandrel moves in a circle in isolation backing plate endoporus, to slide plate
It is made that spacing, by controlling the size of mandrel to can control the gap of slide plate and cylinder body, realizes without friction operating in advance.Due to
Without the sliding friction between slide plate and cylinder body, slide plate tip can reach very high linear velocity, and rotating speed can reach that tradition is set
More than 3 times of meter.Due to breaching the limitation of sliding friction surface linear velocity, not only rotating speed can be greatly promoted, and volume can also
Increase, after the machine amplification, the huge revolving unit that bore is up to DN200 can be made, substitute roots blower/lobe pump, it is multistage from
Heart blower fan, single-stage high-speed centrifugal blower.With great performance boost, indomitable competitiveness and wide market prospects.
