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 by support, motor, band transmission, follower, back shaft, gear transmission reversing mechanism, hollow shaft, bearing support, hollow leading screw, screw, screw sleeve pipe, connecting sleeve, reversing bar, the electric transmission of the spiral reciprocating type that spring mechanism and jaw clutch form, the commutation of the reversing bar in the electric transmission of its spiral reciprocating type 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, the vacuum compression device that total air escape pipe and total inlet pipe form, piston series connection group in vacuum compression dress, continuous past in cylinder body, return motion, realizing this vacuum compressor integrates and vacuumizes and compression function.Although the structure of the more above-mentioned reciprocating vacuum pump of this reciprocating screw vacuum compressor and reciprocal compressor, there is progress, but still there are some shortcoming and defect in its transmission device, 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; Therefore, the shortcoming and defect existing for above-mentioned technology, the applicant has conceived a kind of circulating positive and negative break-in speed change vacuum compressor, this circulating positive and negative break-in speed change vacuum compressor drives positive and negative break-in speed changing type transmission device by support, motor and the motor drive component that forms with transmission, this positive and negative break-in speed changing type transmission device comprises speed reducer, forward and reverse gear synchronous driven unit, positive and negative deviator and speeder, wherein.This positive and negative break-in speed changing type transmission device is being grasped the transmission scheme of collection high speed → deceleration → break-in → speedup, through speed reducer and positive and negative break-in assembly; The high rotating speed of input is down to after the slow-speed of revolution and break-in, through speeder, slow-speed of revolution speedup is arrived again to the high rotating speed of output shaft, by the output shaft in positive and negative break-in speed changing type transmission device 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 the increasing speed gearing transmission mechanism in speeder, must have compactness rational in infrastructure, speedup velocity ratio is high, the function that transmission performance is reliable and stable.Therefore, a kind of increasing speed gearing transmission mechanism that is applicable to circulating positive and negative break-in speed change vacuum compressor speeder of innovative development, is very necessary.
