Description

The hydraulic gyration joint of brushed
Technical field
The utility model relates to a kind of hydraulic gyration joint of brushed, is mainly used in the all-hydraulic loop wheel machine of 900T level, belongs to technical field of engineering machinery.
Background technique
Two-part up and down of hydraulic pressure loop wheel machine are need be rotating, and this just exists the oil circuit of rotating part and standing part and the connectivity problem of circuit.The hydraulic gyration joint is made up of solid of rotation, turning axle and lid etc., and in use, the revolution lower bolster of solid of rotation and hydraulic pressure loop wheel machine is fixed, and the mounting plate on the turning axle supports with the revolution on the revolution upper mounting plate and is connected.Hydralic hose and electric wire are installed on respectively on each hydraulic fluid port and circuit of solid of rotation and turning axle, and the upper mounting plate of hydraulic machinery then drives the turning axle rotation.
Yet swivel coupling in the past is relatively poor with extraneous sealability; Extraneous dust creeps in the swivel coupling easily; Influenced the performance of swivel coupling, and the oil in the swivel coupling spills easily also, solid of rotation in the swivel coupling and turning axle are relatively rotated also produced influence; Need often oil, increase working strength of workers.
And after the hydraulic gyration joint of brushed connected the hydraulic pipe line and circuit of standing part and rotating part in hydraulic system and the circuit in the past; Can not let standing part and rotating part rotate 360 ° relatively; Cause oil circuit upper and lower not smooth; Each oil circuit and circuit operation series connection cause the hydraulic pressure loop wheel machine can not carry out more complicated actions, have limited its applicability.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, provides a kind of dust to be difficult for getting into, and oil is difficult for spilling, and each oil circuit and circuit operation are not connected, and have improved the hydraulic gyration joint of the brushed of hydraulic pressure loop wheel machine applicability.
The purpose of the utility model is achieved in that
The hydraulic gyration joint of the utility model brushed; Comprise solid of rotation and turning axle, insert in the solid of rotation from the top axial of solid of rotation the lower end of said turning axle, and the upper end of turning axle is exposed to solid of rotation; The lower end of said turning axle is provided with baffle plate; The below of said baffle plate is provided with brush, and said brush is provided with the brush alignment pin, and said brush connects through the lower ends of brush locating stud and turning axle; The periphery of said brush is provided with lid, and said lid is through being bolted to the lower end of solid of rotation.
O type circle, wear ring, rotating seal ring and dust ring are housed in the annular groove between said solid of rotation and the turning axle; The side that this dust ring contacts with turning axle is provided with two lips up and down; Form the lips mouth, should be up and down two lips all be adjacent to the outer wall of turning axle.
Said turning axle axially offers eight working connection holes and draining hole, a center; The center of turning axle is located in draining hole, said center; The periphery in said eight working connection pore size distribution draining holes in the center; The termination, upper end in said eight working connection holes is all blocked with plug, radially have on the said solid of rotation eight main hydraulic fluid ports with turning axle on corresponding one by one being connected of eight working connection holes.
Compared with prior art, the beneficial effect of the utility model is:
The hydraulic gyration joint of this brushed can connect the hydraulic pipe line and the circuit of standing part and rotating part in whole hydraulic system and the circuit; And make standing part and rotating part can rotate 360 ° relatively; It is unimpeded that upper and lower oil circuit and circuit can keep; Each oil circuit and circuit operation are not connected, and make the hydraulic pressure loop wheel machine can carry out more complicated actions, have improved its applicability.And it makes lips degree of lip-rounding formula with dust ring; The one side that this dust ring contacts with turning axle is provided with two lips up and down, and the top and the turning axle of two lips fit tightly up and down, makes extraneous dust be difficult for creeping in the swivel coupling; And oil can not spill internally; Thereby guaranteed the performance of swivel coupling, need not often to oil, reduced working strength of workers.
