Abstract
The utility model discloses a direct-current slotless brushless oil-less lubricating air compressor. A cylinder (7) is arranged on a shell (1), a cylinder sleeve (8) is arranged in the cylinder (7), and a piston (3) is arranged in the cylinder sleeve (8) and is arranged on an eccentric wheel (13) with a connecting rod (4) by a bearing. A cylinder cover (2) is arranged on the cylinder body (7), and a valve plate (11) is arranged between the cylinder cover (2) and the cylinder body (7). A stator (5) is arranged in the shell (1), a rotor (6) is positioned in the stator (5) which is composed of an iron core and a coil, and side of the rotor (6) in the shell (1) is provided with a detecting assembly. The utility model has the advantages that a direct-current motor without a slot, a brush and oil for lubrication is used as drive, a non-contact electron is used for detecting the direction change, and the utility model obtain the advantages of stable starting, low noise in operation, stable operation and no electromagnetic interference.
Description
Technical field
The utility model relates to the air compressor field that the direct current air compressor field more particularly relates to the direct current oil-free lubrication.
Background technique
At present, the air compressor that people use is the direct current non-lubricated air compressor mostly, generally comprise cylinder body, cylinder cap, piston, connecting rod and by stator, rotor, end cap, the direct current generator that commutator and carbon brush are formed, piston is fixed on the rotor by connecting rod, commutator is fixed on the rotor, carbon brush is installed on the end cap by brush holder and contacts with commutator, use this kind direct current generator when starting, the energising moment electric current bigger, easily power supply is impacted, when machine operation, carbon brush and commutator friction, produce noise and electromagnetism spark, the electromagnetism spark pair uses the electronic instrument of same power supply to cause electromagnetic interference with motor, influences the proper functioning of electronic instrument, safeguarded the loaded down with trivial details of ten minutes, behind carbon brush and commutator wear, rotating speed of motor and power descend, and must change wear-out part could proper functioning.
The model utility content
The utility model provides a kind of and starts steadily in order to solve above-mentioned deficiency, during running work low, the running of noise steadily, no electromagnetic interference, direct current brushless slotless non-lubricated air compressor that efficient is high.
The technical solution that the utility model is taked in order to solve the problems of the technologies described above is as follows:
A kind of direct current brushless slotless non-lubricated air compressor, comprise housing 1, cylinder cap 2, be provided with the connecting rod 4 of piston 3, stator 5, rotor 6, eccentric wheel 13, housing 1 is provided with cylinder body 7, cylinder sleeve 8 is installed in the cylinder body 7, piston 3 place in the cylinder sleeve 8 and with connecting rod 4 by Bearing Installation on eccentric wheel 13, cylinder cap 2 is installed on the cylinder body 7, at cylinder cap 2 and 7 of cylinder bodies valve plate 11 is installed, stator 5 is installed in the housing 1, rotor 6 is positioned at stator 5, and the rotating shaft 9 that makes rotor 6 is positioned at the eccentric opening of eccentric wheel 13, it is characterized in that: stator 5 is made up of iron core and coil two-part, iron core is the cylindrical shape that silicon steel plate stacking becomes slotless, and coil becomes cylindrical shape to be installed on the iron core, the rotor 6 other detection components that are equipped with in housing 1.
