Embodiment
Below in conjunction with Figure of description, the utility model is described further:
A kind of twin-tub, without oily direct connection air compressor, comprises motor 1, crankcase 8 and wind scooper 10, and crankcase 8 coordinates the side being arranged on motor 1, and the wind scooper 10 of band air guide channel is equipped with the opposite side at motor 1; Above crankcase 8, two cover piston apparatus are set in an angle, often overlap piston apparatus to form by the oscillating bar assembly 5 be equipped with, cylinder 9, valve plate and cylinder cap, cylinder 9, valve plate and cylinder cap are all be fixed on crankcase 8 that (this structure is routine techniques, repeat no more), oscillating bar assembly 5 is made up of the gland 5.3 of fork 5.1, leather cup 5.2 and fixing leather cup, leather cup 5.2 is arranged on the upper end of fork 5.1, and fork 5.1 is slidably arranged in cylinder 9; Motor is provided with live axle 2, and the live axle being positioned at crankcase side is provided with crank throw 4, and crank throw 4 rotates under the drive of live axle in crankcase; The eccentric shaft of crank throw is provided with two cover bearings, the lower end that two cover bearings are respectively inboard bearing 3 and outboard bearing 6, two groups of forks 5.1 is socketed respectively and is arranged on inboard bearing 3 and outboard bearing 6.
Be set to notching construction as preferred fork 5.1 lower end, fork 5.1 is locked with inboard bearing 3, outboard bearing 6 by locking nut 5.4 and is coordinated (two overlap oscillating bar assembly structure identical).Particularly, have otch bottom fork 5.1, be furnished with locking nut 5.4, when locking nut 5.4 is not locked, the installation endoporus below fork 5.1 can become large a little, convenient installation; Oscillating bar assembly 5 is constrained in cylinder 9, and leather cup 5.2 axially can only do the up and down reciprocatingly swing of band beat along cylinder 9.Oscillating bar assembly 5, before not locking, can move left and right along the axis of crank throw 4 lower end, to ensure that the leather cup center of oscillating bar assembly 5 can aim at the center of cylinder 9 automatically, avoid because personal factor causes installation deviation.
