Description
Technical field
The invention belongs to vacuum compressor, become particularly to a kind of circulating positive and negative break-in speed change vacuum compressor
To the spring duckbilled key of gear shaft.
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；

The electric transmission of the spiral reciprocating type of embedded-type clutch composition, in the electric transmission of its spiral reciprocating type
The commutation of reversing bar rotates, and drives by cylinder body, piston, sealed joint pipe, sealing member first, middle separate space, close
Sealing second, front separate space, rear separate space, triplet type intake valve, triplet type air bleeding valve, middle triplet type air bleeding valve,
Middle triplet type intake valve, total air escape pipe and the vacuum compression device of total inlet pipe composition, in vacuum compression dress
Piston series connection group, constantly in cylinder body past, return motion, it is achieved this vacuum compressor collection evacuation and pressure
Contracting function is in one.Although the more above-mentioned reciprocating vacuum pump of this reciprocating screw vacuum compressor and reciprocating pressure
The structure of contracting machine, has had progress, but its actuating device there are still some drawbacks and deficiency, topmost scarce
Point is its jaw clutch be prone to when normal work de-knot and its actuating device can not at high-speed condition under enter
The normal work of row, the efficiency of the evacuation and compression function that constrain vacuum compressor improves；Therefore, for
The shortcoming and defect that above-mentioned technology exists, the applicant contemplates a kind of circulating positive and negative break-in speed change Vacuum Pressure
Contracting machine, the motor that this circulating positive and negative break-in speed change vacuum compressor is made up of support, motor and V belt translation
Driving Component driver positive and negative break-in speed changing type actuating device, this positive and negative break-in speed changing type actuating device includes slowing down
Device, forward and reverse gear synchronous drive assembly, positive and negative deviator and speeder, and the most positive and negative break-in fills
Put and include change gear axle, a change gear, upper Lower shaft sleeve, break-in scroll key, spring duckbilled key, break-in tooth
Wheel b, upper and lower end cap, freewheel clutch and forward and reverse change gear mechanism of freewheel clutch set composition, and
Break-in mainshaft mechanism includes break-in main shaft, first change gear, the third change gear, fourth change gear, second break-in
Gear, diverter, Bunper assembly.This positive and negative break-in speed changing type actuating device grasp collection at a high speed → slow down →
The transmission scheme of break-in → speedup, through deceleration device and positive and negative break-in assembly；The high rotating speed of input is down to low
After rotating speed and break-in, again through speeder by the high rotating speed of slow-speed of revolution speedup to output shaft, by positive and negative break-in
Output shaft in speed changing type actuating device drives the piston series connection group in vacuum compression device constantly to exist with high rotating speed
Vacuum compression cylinder body past, return motion, it is achieved the efficient function of the evacuation of this vacuum compressor and compression；
To this end, require the spring duckbilled key of circulating positive and negative break-in speed change vacuum compressor change gear axis mechanism,
Must have rational in infrastructure compact and that transmission performance is reliable and stable function.Therefore, innovative development one is suitable for
In the spring duckbilled key of circulating positive and negative break-in speed change vacuum compressor change gear axle, it is the most necessary.
Summary of the invention
It is contemplated that in place of in order to avoid shortcoming and defect present in above-mentioned technology, grasp and make transmission fill
