Abstract
A position stop piece structure of a drainage pump comprises a permanent magnet rotor provided with a start lug boss, and a position stop piece provided with a stop block; the position stop piece is fixedly connected with a rotor shaft; rubber pads are arranged on two sides of the start lug boss; and rubber blocks are arranged on two sides of the stop block. Convex points are formed on two sides of the rubber blocks, and the surfaces of two rubber pads adopt flat surfaces; or two sides of the rubber blocks adopt flat surfaces, and convex points are formed on the surfaces of two rubber pads. The collision between the plastic and rubber (or the collision between the metal or the rubber) caused when the traditional drainage pump is started is improved to be the collision between the rubbers, so that the collision noise is lowered; meanwhile, two sides of the rubber blocks are designed as the flat surfaces with convex points, so that the collision between the rubber block and the rubber pad changes from point collision to surface collision, and the collision noise is further lowered; meanwhile, due to the collision between the rubbers, the impact of collision force to the rubber parts is alleviated, and the service life of the rubber parts is improved. Therefore, the position stop piece structure has the advantages of simple and reasonable structure, convenient installation, low collision noise, and convenient popularization.
Description
Technical field
The utility model relates to a kind of centrifugal draining pump, especially is applicable to the gear spare structure of the centrifugal miniature draining pump of household electric appliance.
Background technique
At present, solving the main method that starts noise between miniature draining pump p-m rotor and the gear spare is in the both sides of gear spare block rubber to be set, its collision is plastics and rubber collision, collision process is that face contacts with face or contacted to face by line, because working of plastics is a rigid element, its collision noise is still very big.As Chinese patent literature CN2931869Y in disclosed miniature draining pump on August 8th, 2007, this structure is being collided to face by line of plastics and rubber, its collision noise is still bigger, and this structure rubber cylinder is stuck in hollow cylinder easily, causes burn-down of electric motor.
The model utility content
The purpose of this utility model aims to provide the gear spare structure of a kind of simple and reasonable, low noise, high-intensity draining pump, to overcome deficiency of the prior art.
Press the gear spare structure of a kind of draining pump of this purpose design, comprise and be provided with p-m rotor that starts boss and the gear spare that is provided with block, gear spare is fixedlyed connected with rotor shaft, and its structure characteristic is to start the boss bi-side to be provided with rubber pad, and the block bi-side are provided with block rubber.
Described startup boss is a sector structure, and its bi-side axially are provided with groove, and the slot opening place is provided with the necking down position; Rubber pad is a sector unit, and respective slot is provided with protruding stupefied, protruding stupefiedly cooperate with recess-mounted.Perhaps, described startup boss is a sector structure, and end face is provided with the groove that is communicated with bi-side; Be arranged between the rubber pad that starts the boss bi-side and connect as one by connecting tendon, be I-shaped or door shape, connecting tendon cooperates with recess-mounted.
Described gear spare is cylindric, and a surperficial side shaft is to being provided with fan-shaped boss, and the annulated column of fixedlying connected with rotor shaft is extended in the centre, annulated column towards a side shaft of fan-shaped boss to being provided with the annulated column boss; Block is made up of fan-shaped boss and annulated column boss, is provided with block rubber between fan-shaped boss and the annulated column boss; The block rubber cross section is similar M shape or waveform, middle part and annulated column boss chucking, and both sides and fan-shaped boss are close to.
Described gear spare periphery is provided with thin walled cylinder, and the thin walled cylinder inwall extends fan-shaped boss.
Described block rubber bi-side are provided with salient point, and two rubber pad surfaces are the plane; Perhaps, the block rubber bi-side are the plane, and two rubber pad surfaces are provided with salient point.
Plastics and rubber collision when the utility model starts traditional draining pump (or metal and rubber collision) are improved as rubber and rubber collision, have reduced collision noise.The block rubber bi-side are designed to have the plane of salient point simultaneously, make that the collision process of block rubber and rubber pad is the collision process of spreading over a whole area from one point, and have further reduced collision noise.Rubber has alleviated the impact of impact force to rubber parts, the working life of having improved rubber parts to the collision of rubber simultaneously.It is simple and reasonable, easy for installation, collision noise is little, be convenient to popularization.
