Abstract
A high-speed rotating joint applicable to high and low pressure fluid consists of a rotating shaft joint (1), a self-lubricating sliding bearing (2) at the inner side, an 'O'-type rubber dust-proof sealing ring (3), a screw cap (4), a steel ball (5), a bearing moving coil (6), a steel wire snap ring for a shaft (7), a radial retaining ring (8), a gasket (9), a self-lubricating sliding bearing (10) at the outer side, right-angle seal filled with tetrafluorine (11), an 'O'-type sealing ring (12) and a shaft bushing joint (13), and is characterized in that: the self-lubricating sliding bearing (2) at the inner side, the 'O'-type rubber dust-proof sealing ring (3), the screw cap (4), the steel ball (5), the bearing moving coil (6), the steel wire snap ring for a shaft (7), the radial retaining ring (8) and the gasket (9) are sequentially sheathed on the shaft at a shaft end of the rotating shaft joint (1); and the 'O'-type sealing ring (12), the right-angle seal filled with tetrafluorine (11) and the self-lubricating sliding bearing (10) at the outer side are sequentially arranged in a hole of the shaft bushing joint (13) which is sheathed on the screw cap (4) and matched with the screw cap (4) by thread to form a closed whole body and achieve the purpose of the design.
Description
Technical field
The utility model relates to a kind of high-speed joint that is applicable to the high low pressure fluid.
Background technique
Progress along with society, Development in Machine Industry, all kinds of high-speed joints have obtained using widely, but the existing most complex structure of high-speed joint that is applicable to high low pressure, bulky, perishable, it is unreliable to seal, and bind mode is restricted, rotating speed is low, has limited it again and has applied.
Summary of the invention
The purpose of this utility model is a kind of addressing the above problem of development, compact structure, reliable performance, the unrestricted high-speed joint that is applicable to the high low pressure fluid of bind mode.
The utility model is achieved through the following technical solutions:
The utility model is mainly by shaft joint, inboard self-lubricating plain bearing, " O " type rubber dust-proof seal ring, blind nut, steel ball, the bearing moving-coil, axle-steel silk back-up ring, baffle ring radially, packing ring, outside self-lubricating plain bearing, fill the sealing of tetrafluoro right angle, " O " RunddichtringO and axle sleeve joint are formed, it is characterized in that: inboard self-lubricating plain bearing, " O " type rubber dust-proof seal ring, blind nut, steel ball, the bearing moving-coil, axle-steel silk back-up ring, radially baffle ring and packing ring are enclosed within on the axle head axle of shaft joint in proper order, and scribble lubricating grease, " O " RunddichtringO, filling sealing of tetrafluoro right angle and outside self-lubricating plain bearing is set in sequence in the axle sleeve nipple orifice, the axle sleeve joints sleeve is on blind nut, screw-thread fit, form closed whole, shaft joint wherein, blind nut and axle sleeve joint are passing hole types, shaft joint and blind nut have the assembly technology hole, during use, the thrust that fluid forms is delivered on the steel ball by axle-steel silk back-up ring and bearing moving-coil, formed a plain thrust bearing, make rotational resistance reduce to minimum, inboard self-lubricating plain bearing, outside self-lubricating plain bearing conduct is self-lubricating plain bearing radially, the supporting revolving shaft joint is around the axle center rotation effectively, guarantee to rotate brisk reliable with sealing, fill the sealing of tetrafluoro right angle and " O " RunddichtringO and form U type combination seal, guaranteed height, the reliability of low pressure seal, the variation of the mode that outreaches by shaft joint and axle sleeve joint, this swivel joint can be formed any bind mode, reach purpose of design.
This reality is novel to have following advantage:
1, via enforcement of the present utility model, whole apparatus structure compactness, volume is little.
2, via enforcement of the present utility model, owing to the Sealing material can be selected, and the position is forward, and parts such as bearing all do not contact with flowing medium, have prevented corrosion, can use at gas, water, any fluid of wet goods, and are applied widely.
3, via enforcement of the present utility model, adopted the method for self-lubricating plain bearing and plane rolling bearing combination, efficiently solve the thrust behind part frictional force and the pressurized, rotate flexibly.
4, via enforcement of the present utility model, adopt and fill the sealing of tetrafluoro right angle, high and low pressure all is suitable for, and the seal friction coefficient is low, intensity good, the life-span is long, and sealing is reliable.
5,, can realize the high rotating speed of Sealing 5M/S with interior relative movement via enforcement of the present utility model.
6, via enforcement of the present utility model, the variation of the mode that outreaches by shaft joint and axle sleeve joint can form this swivel joint any bind mode.
