Abstract
The utility model relates to a transmission mechanism of a high precision constant flow pump, which comprises a connecting rod which is used for driving a pump body of a bellow type constant flow pump to work and a motor rotating shaft which is used for driving an eccentric shaft neck to rotate. The utility model is characterized in that the lower end of the connecting rod is provided with a sleeve ring which is sheathed on the periphery of the eccentric shaft neck, and two or more than two bearings are arranged between the outer perisporium of the eccentric shaft neck and the inner perisporium of the sleeve ring. When the utility model is applied to a bellow type constant flow pump, the utility model not only can ensure that a bellow pump body has a working stroke with high stability, but also can be favorable to reducing wear between the connecting pieces because of the connection of the motor and the bellow pump body.
Description
Technical field
The utility model relates to a kind of in order to drive bellow type constant flow pump transmission operated.
Background technique
Constant flow pump be a kind of can be with the common equipment of constant flow delivery liquid, in field extensive application such as scientific research, industry, service trades.According to the different designs principle, existing constant flow pump has piston type, flexible pipe creeping type, bellow type etc. dissimilar, and its key technical indexes is constant flow precision, flow adjustable extent, long-term continuous operation stability and price etc.Existing commodity often respectively have pluses and minuses on above-mentioned all index, perhaps have highi degree of accuracy but range of flow is little and cost an arm and a leg, and perhaps have big range of flow but precision is not good enough, or the like, all can not on above-mentioned all index, have advantage concurrently.For example existing bellow type constant flow pump, though range of flow is big, cheap, but since its in order to the connecting rod that drives the bellowspump body running with in order to only to connect between the machine shaft of transferring power and the eccentric journal by single bearing or axle sleeve, thereby connecting rod is when transferring power, also can produce the beat of all directions all around, not only influence the working stability of the bellows pump housing, thereby reduced its flow operating accuracy greatly, and caused the wearing and tearing between the link easily.
Summary of the invention
The purpose of this utility model is to provide a kind of driving mechanism of high precision constant current pump, when this mechanism is applied to the bellow type constant flow pump, by it motor is connected with the bellows pump housing, can guarantee that not only the bellows pump housing has the working stroke of high stability, and help reducing the wearing and tearing between the link.
The utility model is to constitute like this, it comprises in order to the connecting rod that drives the work of the bellow type constant flow pump pump housing with in order to drive the machine shaft that eccentric journal rotates, it is characterized in that: described connecting rod lower end is provided with the collar that is placed on the eccentric journal periphery, is provided with two or more bearings between described eccentric journal periphery wall and the collar inner circle wall.
During work, utilization drives the eccentric journal rotation by the monolithic processor controlled stepper motor that has by a certain fixed rotating speed work that sets in advance by rotating shaft, and eccentric journal stably promotes the bellows pump housing correspondingly according to a certain stable stroke work along a certain axis by two or more bearing drivening rods.
Than prior art, the utility model is owing to adopt two or more bearings to connecting in order to the eccentric journal of transferring power with in order to the connecting rod that drives the work of the bellow type constant flow pump pump housing, thereby connecting rod is not easy to produce the beat of other direction when work, guarantee that not only the bellows pump housing has the working stroke of high stability, thereby improve the flow operating accuracy of bellow type constant flow pump, but also help reducing wearing and tearing between the link, make it have highi degree of accuracy concurrently, range of flow is big, long-term continuous operation is stable, all advantages such as the life-span is long and cheap.

Embodiment
The utility model embodiment comprises in order to the connecting rod 2 that drives 1 work of the bellow type constant flow pump pump housing with in order to drive motor 4 rotating shafts 5 that eccentric journal 3 rotates, it is characterized in that: described connecting rod lower end is provided with the collar 6 that is placed on the eccentric journal periphery, is provided with two or more bearings 7 between described eccentric journal periphery wall and the collar inner circle wall.
The above-mentioned rotating shaft that is connected in the eccentric journal left and right sides links through bearing 8 and fixed support 9 respectively.
Application of the present utility model helps not only guaranteeing that the bellows pump housing has the working stroke of high stability, thereby improve the flow operating accuracy of bellow type constant flow pump, but also help reducing wearing and tearing between the link, all advantage such as make it have that big, the long-term continuous operation of highi degree of accuracy, range of flow is stable, the life-span is long concurrently and cheap, its simple structure, easy to use has bigger application value.
