Abstract
The invention discloses a raised tri-wheel assembly of a diaphragm pump. The raised tri-wheel assembly is an injection molding piece and consists of a bearing sleeve and three balance wheels uniformly distributed on the bottom end of the bearing sleeve; an eccentric bearing is embedded and fixed in the bearing sleeve; a metal bushing is embedded into the chamber wall of a bearing chamber of the bearing sleeve; the eccentric bearing is embedded into the metal bushing. Since the metal bushing is embedded into the bearing chamber of the raised tri-wheel injection molding piece, the rigidity and the precision of the bearing chamber can be ensured, and the axial shift of a bearing possibility happing in a long-term transfer process can be avoided; the cost can be saved and the production efficiency can be improved.
Description
Technical field
The present invention relates to diaphragm pump technical field, relate in particular to the mini electric diaphragm pump be applied on drinking machine.
Background technique
At present, some drinking machines are provided with mini electric diaphragm pump to realize electronic drawing water.Convex three-wheel in the middle of diaphragm pump is the vitals of transferring power, be made up of a bearing housing and three escapements being evenly laid in bearing housing bottom, setting-in in bearing housing is also fixed with capacity eccentric bearing, be the front and back periodic reverse motion of escapement the converting rotary motion of motor by capacity eccentric bearing, escapement is utilized to promote barrier film front-rear reciprocation movement, the volume of work chamber is made to make periodically-varied, force the unidirectional valve pad being located at water intake and water outlet alternately to open and close, thus water is constantly sucked and discharges.Therefore, bearing chamber will bear very large axial force.Convex three-wheel in the past is generally made Al-alloy parts and just can be met the demands, but cost is high.For cost-saving, also have and convex three-wheel is made moulding, and install end ring additional being positioned at outside convex three-wheel bearing chamber, by back-up ring, capacity eccentric bearing is fixed, prevent bearing axial float.This configuration reduces cost, but plastic materials hardness is not enough, precision is difficult to ensure, after running a period of time, the bearing in bearing chamber easily loosens, and causes diaphragm pump to vibrate, and produces noise.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of capacity eccentric bearing that makes and is inlaid in convex tricycle assembly in convex three-wheel bearing chamber securely.
For solving the problems of the technologies described above adopted technological scheme: a kind of convex tricycle assembly of diaphragm pump, this convex three-wheel is a moulding, be made up of a bearing housing and three escapements being evenly laid in bearing housing bottom, one capacity eccentric bearing setting-in is also fixed in bearing housing, it is characterized in that: the bearing chamber wall of described bearing housing is inlaid with metal lining, and described capacity eccentric bearing is then inlaid in metal lining.
On the basis of the above, the bottom of described metal lining is formed with flange, flange at least has a slotted eye, and this slotted eye can make metal lining can be combined with moulding securely when described moulding molding and forming.The opening end of described metal lining is formed with some lining ears in order to compress described capacity eccentric bearing.Can preferably, the material of described metal lining is stainless steel or carbon steel.
Adopt the beneficial effect that the present invention brings: because the convex three-wheel moulding of the present invention is inlaid with metal lining in bearing chamber, rigidity and the precision of bearing chamber can be ensured like this, prevent the axial float that bearing may occur in long-term operation process; Again can be cost-saving, enhance productivity.
Accompanying drawing explanation
Fig. 1 is the structural representation of the convex tricycle assembly of diaphragm pump of the present invention.
Embodiment
As shown in Figure 1, a kind of convex tricycle assembly of diaphragm pump, this convex three-wheel is a moulding, is made up of a bearing housing 1 and three escapements 2 being evenly laid in bearing housing 1 bottom.The bearing chamber wall of bearing housing 1 is inlaid with metal lining 3, in concrete enforcement, is that metal lining 3 is reserved mould together with the injection mould of convex three-wheel, and then molding and forming, utilizes the cooling meat of moulding that metal lining 3 is embedded on moulding securely.In order to make metal lining 3 be combined with moulding more securely, the bottom of metal lining 3 is formed with flange 4, flange 4 at least has a slotted eye 5, and when molding and forming, plastics can be filled into those spaces on flange 4, and both are combined closely.The opening end of metal lining 3 is formed with some lining ears 6, capacity eccentric bearing 7 is inlaid in the bearing chamber of bearing housing 1, and then with press, lining ear 6 is bent, the outer ring of capacity eccentric bearing 7 is fixed, certainly also by other conventional method, capacity eccentric bearing 7 can be fixed in bearing housing 1.In order to strengthen the serviceability of metal lining 3, metal lining 3 adopts stainless steel or carbon steel impact briquetting.
Claims (4)
1. the convex tricycle assembly of a diaphragm pump, this convex three-wheel is a moulding, be made up of a bearing housing and three escapements being evenly laid in bearing housing bottom, one capacity eccentric bearing setting-in is also fixed in bearing housing, it is characterized in that: the bearing chamber wall of described bearing housing is inlaid with metal lining, and described capacity eccentric bearing is then inlaid in metal lining.
2. the convex tricycle assembly of a kind of diaphragm pump as claimed in claim 1, it is characterized in that: the bottom of described metal lining is formed with flange, flange at least has a slotted eye, this slotted eye can make metal lining can be combined with moulding securely when described moulding molding and forming.
