Description

technical field

[0001] The invention belongs to vacuum compressors, in particular to a speed-increasing gear transmission mechanism of a cycle-type forward and reverse variable-speed vacuum compressor speed-increasing device. Background technique

[0002] At present, in mechanical products, such as mechanical transmission devices of reciprocating vacuum pumps and reciprocating compressors, most of its structures adopt motors, belt transmissions to drive crankshafts and eccentric wheel-type transmission mechanisms. The reciprocating motion is realized by using the slider and the connecting rod to cooperate to push the piston. Due to the restriction of the above-mentioned transmission mode, the distribution form of the cylinder body can only be V-shaped, fan-shaped or parallel twin-cylinder type. Due to the periodic inflection point or dead point in the transmission of the crankshaft and the eccentric wheel—that is, the dead point where the output torque is "0"; the transmissi...
