Description
Technical field
The invention belongs to vacuum compressor, particularly the speeder of the positive and negative break-in variable transmission mechanism of a kind of vacuum compressor.
Background technique
At present, in engineering goods, such as the mechanical transmission of reciprocating vacuum pump and reciprocal compressor, its structure mostly adopts motor, with the driving mechanism of transmission driving crank and eccentric wheel type.By adopting slide block and connecting rod to coordinate promotion piston to realize to-and-fro motion, owing to being subject to the restriction of the above-mentioned kind of drive, its cylinder body distribution form can only be V-type, fan type or twin-tub type in parallel.Due to bent axle and eccentric wheel transmission existence periodicity flex point or dead point---export the dead point that torque is " 0 "; During transmission, will inevitably cause vibrations and noise, and bent axle and eccentric gearing do not have reinforcement coefficient; So power consumption is just large, especially when compression ratio---when head pressure/incoming pressure is larger, power consumption is very uneconomic.This is also why toward trans vacuum pump and past trans compressor, to be the reason of autonomous device at present; And these are independently toward trans vacuum pump and independently many toward trans compressor both parts, not only Heavy Weight but also structure were not compact.In recent years, the problem existing in order to solve the mechanical transmission of above-mentioned reciprocating vacuum pump and reciprocal compressor, the vertical figure of people is large from utilizing power screw to have reinforcement coefficient, the accurate characteristic that operates steadily is set out, in conjunction with adopting elastic force to control the round reversing arrangement of leading screw, and researched and developed a kind of reciprocating screw vacuum compressor that the patent No. is ZL201110158356.4, its structure comprises motor, follower back shaft, gear transmission reversing mechanism, hollow shaft, bearing support, hollow leading screw, screw, screw sleeve pipe, connecting sleeve, reversing bar, the reciprocating screw transmission mechanism that spring mechanism and jaw clutch form, the commutation of the reversing bar in its reciprocating screw transmission mechanism is rotated, drive is by cylinder body, piston, sealed joint pipe, Sealing first, middle separate space, Sealing second, front separate space, rear separate space, three-way type suction valve, three-way type outlet valve, middle three-way type outlet valve, middle three-way type suction valve, piston series connection group in the vacuum compression device that total air escape pipe and total inlet pipe form, continuous past in cylinder body, return motion, realize the function that vacuumizes with compress of this vacuum compressor.Although the structure of the more above-mentioned reciprocating vacuum pump of this reciprocating screw vacuum compressor and reciprocal compressor, there is progress, but its transmission device is still deposited shortcoming and defect, topmost shortcoming is that its jaw clutch is easy to de-knot when normal work and its transmission device can not normally be worked under high-speed condition, has restricted vacuumizing with the efficiency of compression function of vacuum compressor and has improved; What therefore, for above-mentioned technology, exist is scarce and not enough; The applicant's innovation thinking a kind of circulating positive and negative break-in speed change vacuum compressor, this circulating positive and negative break-in speed change vacuum compressor is to adopt positive and negative break-in speed changing type electric transmission to drive vacuum compression device, comprise: by support, motor with the motor drive component of transmission, drive the positive and negative break-in speed changing type transmission device being comprised of the gear assembly of deceleration assembly, positive and negative rotation, positive and negative deviator and speeder, wherein speeder comprises break-in spindle part and the increasing speed gearing transmission assembly in forward and reverse deviator; The vacuum compressor of this circulating positive and negative break-in speed change is being grasped the transmission scheme with high speed → deceleration → break-in → speedup, by speed reducer and positive and negative deviator, the high rotating speed of input is down to the slow-speed of revolution and after the positive and reverse steering of deviator, through speeder, slow-speed of revolution speedup is arrived again to the high rotating speed of output shaft, by the output shaft in its positive and negative break-in speed changing type driving mechanism with high rotating speed drive piston series connection group in vacuum compression device constantly vacuum compression cylinder body past, return motion, realize the efficient function that vacuumizes with compress of this vacuum compressor.For this reason, require speeder in positive and negative break-in speed changing type transmission device must there is compactness rational in infrastructure and speed increasing ratio high, the reliable and stable superior function of transmission performance.Therefore, a kind of speeder that is applicable to circulating positive and negative break-in speed change vacuum compressor of innovative development, is very necessary.
