Description
Technical field
The invention belongs to vacuum compressor, particularly to a kind of circulating positive and negative break-in speed change vacuum compressor
Deceleration device.
Background technology
At present, the mechanical driving device of such as reciprocating vacuum pump and reciprocating compressor in engineering goods,
Its structure mostly uses motor, V belt translation to drive the drive mechanism of bent axle and eccentric wheel type.Sliding by using
Block and connecting rod coordinate promotion piston to realize moving back and forth, and owing to being restricted by the above-mentioned kind of drive, its cylinder body divides
Cloth form can only be V-type, fan or twin-tub type in parallel.Turn owing to bent axle and eccentric transmission exist periodicity
Point or dead point i.e. export the torque dead point for " 0 "；Vibrations and noise will necessarily be caused during transmission, and
Bent axle and eccentric gearing do not have reinforcement coefficient；So power consumption is the biggest, especially discharge when compression ratio
When pressure/input pressure is bigger, power consumption is the most uneconomic.Why this is also at present toward trans vacuum pump
With the reason toward trans compressor being autonomous device；And these independent past trans vacuum pumps and independent toward anti-
Formula compressor both parts are many, and not only Heavy Weight but also structure were the compactest.In recent years, in order to solve above-mentioned reciprocating very
The problem that the mechanical driving device of empty pump and reciprocating compressor exists, people found figure from utilizing worm drive to have
Having reinforcement coefficient big, the accurate characteristic that operates steadily is set out, in conjunction with the round commutation using elastic force to control leading screw
Device, and researched and developed a kind of reciprocating screw vacuum compressor of Patent No. ZL201110158356.4；
Its structure includes motor, driven pulley support shaft, gear drive exchange system, hollow axle, bearing block, hollow
Leading screw, screw, screw sleeve pipe, adapter sleeve, reversing bar, spring mechanism and the spiral shell of jaw clutch composition
Rotation reciprocating transmission, the commutation of the reversing bar in its reciprocating screw transmission mechanism rotates, and drives by cylinder
Body, piston, sealed joint pipe, sealing member first, middle separate space, sealing member second, front separate space, rear separate space, three
Flow-through intake valve, triplet type air bleeding valve, middle triplet type air bleeding valve, middle triplet type intake valve, total aerofluxus
Pipe and total inlet pipe composition vacuum compression device in piston series connection group, constantly in cylinder body past, return fortune
Dynamic, it is achieved the evacuation of this vacuum compressor and the function of compression.Although this reciprocating screw vacuum compressor
More above-mentioned reciprocating vacuum pump and the structure of reciprocating compressor, had progress, but its actuating device still deposited
Shortcoming and defect, topmost shortcoming is that its jaw clutch is prone to de-knot and its transmission when normal work
Device normally can not work under high-speed condition, constrains evacuation and the compression function of vacuum compressor
Efficiency improve；Therefore, lack and not enough for what above-mentioned technology existed；The applicant innovation thinking one
Circulating positive and negative break-in speed change vacuum compressor, this circulating positive and negative break-in speed change vacuum compressor is to use
Positive and negative break-in speed changing type electric transmission drives vacuum compression device, the most positive and negative break-in speed changing type electric transmission
Mechanism includes: driven by deceleration device, rotating by the motor drive component of support, motor and V belt translation
Dynamic gear assembly, positive and negative deviator and the positive and negative break-in speed changing type actuating device of speeder composition,
Wherein deceleration device includes motor drive component.This positive and negative break-in speed changing type actuating device grasp with at a high speed →
The transmission scheme of deceleration → break-in → speedup, is turned the height of input by deceleration device and positive and negative deviator
Prompt drop to after the positive and reverse steering of the slow-speed of revolution and redirected device, again through speeder by slow-speed of revolution speedup to defeated
The high rotating speed of shaft, drives true by the output shaft in its positive and negative break-in speed changing type drive mechanism with high rotating speed
Piston series connection group in pneumatics compression apparatus constantly vacuum compression cylinder body past, return motion, it is achieved this vacuum
The evacuation of compressor and the efficient function of compression.To this end, require in positive and negative break-in speed changing type actuating device
Deceleration device must have rational in infrastructure compact and impact is little, not uncoupling, dependable performance and stable
Function.Therefore, a kind of deceleration being applicable to circulating positive and negative break-in speed change vacuum compressor of innovative development
Device, is the most necessary.
Summary of the invention
