Abstract

The invention discloses a non-circular gear set and a transmission structure for a pump. The gear set comprises a drive gear, a first driven gear and a second driven gear, wherein the first driven gear and the second driven gear are arranged on the two sides of the drive gear and are of the same structure. The distance between a gear shaft of the first driven gear and a gear shaft of the drive gear is equal to the distance between a gear shaft of the second driven gear and a gear shaft of the drive gear. The transmission structure comprises a driving device, the gear set and a plunger. The driving device is connected with the drive gear in the gear set. Each of the two sides of the drive gear drives one corresponding driven gear. Each driven gear is connected with a connecting rod, and the connecting rod drives the plunger to reciprocate. The driven gears can be made to run stably through the non-circular gear set based on the non-circular gear set and the transmission structure for the pump, and stability of linear motion can be ensured when a crank block device is used for converting the circular motion of the gears into linear motion; and meanwhile by means of a transmission structure in the transmission structure for the pump, the flow pulse generated when the pump drains and outputs liquid can be obviously reduced.

Description

technical field [0001] The present disclosure generally relates to a mechanical transmission structure, in particular to a gear set, and in particular to a non-circular gear set and a pump transmission structure. Background technique [0002] The existing transmission pair for the advection pump can realize the liquid suction and discharge functions of the advection pump, but the pulsation of the output flow is relatively large during the discharge, which cannot meet the demand for constant liquid delivery. [0003] In the prior art, there is also a double-cylinder body, and a retractable high-elastic isolation belt is provided in the two cylinder bodies, which can solve the pulsation problem during liquid discharge, but the pressure-bearing capacity of the shrinkable elastic shrinkable bag is limited, and the increased The space volume of the advection pump is increased. Contents of the invention [0004] In view of the above-mentioned defects or deficiencies in the prio...
