Abstract
The utility model relates to a transmission connection mechanism of a hydraulic diaphragm pump, which comprises a motor, a pump body, an eccentric shaft and a bearing, wherein the motor is fixed on the side wall of the pump body; the bearing is assembled on the pump body; two ends of the eccentric shaft are mounted in the bearing; and an eccentric wheel is convexly arranged in the middle of the eccentric shaft. The transmission connection mechanism is characterized in that a linkage groove is formed at the end part of the eccentric shaft; a corresponding linkage block is arranged at the end part of an output shaft of the motor; and the output shaft of the motor is coaxially linked with the eccentric shaft. The utility model has the advantages of simple and reasonable structure, convenient manufacture and assembly and lower manufacturing cost, and can reduce the weight of the hydraulic diaphragm pump when applied to the hydraulic diaphragm pump and meet the requirement for low flow.
Description
Technical field
The utility model relates to a kind of connection set of diaphragm hydraulic pump, specifically is a kind of transmission connecting mechanism of diaphragm hydraulic pump.
Background technique
Diaphragm hydraulic pump is a kind of pump that is used to produce certain pressure and certain flow, and existing diaphragm hydraulic pump is electronic diaphragm hydraulic pump mostly, and it drives one in front and one in back to-and-fro motion of barrier film on the plunger with motor by speed reducer.In pump chamber, two non-return valves up and down are housed, the motion of barrier film causes the change of the volume in the active chamber, forces two alternately opening and closing of non-return valve, thereby liquid is constantly sucked and exports.The structure of this diaphragm hydraulic pump is complicated, own wt is heavier, fabricating cost is higher and be not suitable for the occasion of small flow.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of simple and reasonable, transmission connecting mechanism of making diaphragm hydraulic pump easy to assembly is provided, the own wt of diaphragm hydraulic pump of using this mechanism is lighter, and fabricating cost is lower and can satisfy the small flow requirement.
The technological scheme that provides according to the utility model, the transmission connecting mechanism of described diaphragm hydraulic pump comprises motor, the pump housing, eccentric shaft and bearing, motor is fixed on the pump housing sidewall, bearing is assemblied on the pump housing, the eccentric shaft two ends are contained in the bearing, and the eccentric shaft middle part convexes with eccentric wheel, and it is characterized in that: described eccentric shaft end is provided with a connection slot, the motor output shaft end is provided with corresponding coupling block, and described motor output shaft connects with the eccentric shaft concentric.
Described pump housing top is provided with bearing bracket, and bearing is assemblied in the bearing bracket.
As further improvement of the utility model, described eccentric shaft adopts stainless steel material to make.
The utility model is simple and reasonable, makes and easy to assembly, when being applied on the diaphragm hydraulic pump, can alleviate the weight of diaphragm hydraulic pump, makes its fabricating cost lower and can satisfy the small flow requirement.
