Abstract
The utility model discloses an oil-free air compressor which consists of a bracket seat, a motor, a centrifugal wheel link mechanism, a piston cylinder mechanism and a divided air passage. Wherein the bracket seat is quadrangular or polygonal; the motor is fixedly connected with the bracket seat through four or a plurality of bolts inside and outside the motor stator; the cylinder is of a step-like structure and is tightly pressed on the bracket seat through the steps by a pressure plate; the motor shaft is connected with the centrifugal wheel by a key. The utility model which has good structural propery, stable operation, low noise, reliable system property, stable quality and convenience for the development of serialization products can be widely applied to the industries of medicine, pharmacy, food and chemical engineering.
Description
The utility model belongs to the mechanical ﹠ electrical technology field, is a kind of small-sized oil-free air compressor.
Oil-free air compressor can provide does not have the clean source of the gas of oil, is widely used in industries such as medical treatment, pharmacy, food, chemical industry.At present, small-sized oil-free air compressor is made up of motor, bracket, eccentric wheel connecting rod mechanism, piston-cylinder mechanism, shunting air flue.By the Cock screw transmitting torque, the axial position of eccentric wheel connecting rod mechanism is also fixed by this Cock screw between motor shaft and the eccentric wheel; Cylinder is pressed on the bracket by seal ring by the cylinder top board, because itself there is defective in this kind structure, makes systematic function unreliable, and running noise is higher, and quality of product is difficult to stablize.
The utility model is to provide a kind of structural behaviour good, and running noise is lower, and systematic function is reliable, steady quality, and be convenient to develop the small-sized oil-free air compressor of tandem product.
The technological scheme that the utility model is taked in the technical solution problem is: bracket is four limits or polygonal, adopt to embed with motor to cooperate, and motor stator is inside and outside all to be connected with the fastening of bracket with four or many support bolts realization motor; Cylinder adopts ledge structure, is pressed in bracket by pressing plate by this step; Motor shaft and eccentric wheel key connecting realize the key transmission.
The beneficial effects of the utility model are: structural behaviour is good, is convenient to assembling and setting, and running is steady, and noise is low, and systematic function is reliable, steady quality, and long service life, and be convenient to develop tandem product.
Below in conjunction with drawings and Examples structure of the present utility model is described further.
Fig. 1 is a complete machine structure figure.Fig. 2 is the bracket right elevation.Fig. 3 is the bracket sectional view.Fig. 4 is the bracket left view.Fig. 5 is the bracket plan view.Fig. 6 is the pressing plate sectional view.Fig. 7 is the pressing plate plan view.Fig. 8 is air cylinder structure figure.Fig. 9 is the motor shaft structural drawing.Figure 10 is the eccentric wheel right elevation.Figure 11 is the eccentric wheel sectional view.
Wherein, 1 is motor; 2 is cylinder; 3 is the cylinder top board; 4 is pressing plate; 5 is the pressing plate set screw; 6 is piston cup; 7 is bracket; 8 is connecting rod; 9 for being the eccentric wheel Cock screw; 10 is key; 11 is motor shaft; 12 is eccentric wheel; 13 is bracket outer fixing bolt; 14 is bracket internal fixation bolt; 15 is bracket outer fixing bolt collar.
Embodiment:
Motor 1 is a 370w capacitor start single-phase asynchronous motor, cylinder 2 external diameters are 72.5mm, internal diameter is 63.4mm, height overall 21.5mm, and pressing plate 4 thickness are 3mm, bracket 7 is a quadrilateral, key 10 is of a size of 5mm, motor shaft 11 length overall 220mm, and the throw of eccentric of eccentric wheel 12 is 11.5mm, respectively 4 on bracket outer fixing bolt 13 and internal fixation bolt 14, each component is processed by designing requirement.This small-sized oil-free air compressor, motor speed are 1400r/min, and the standard exhaust pressure is 0.5Mpa, and maximum exhaust pressure is 0.8Mpa, and the standard air displacement is 60L/min.
