High-voltage high-speed formula swivel joint

Technical field

The utility model relates to a kind of swivel joint, particularly a kind of high-voltage high-speed formula swivel joint.

Background technique

At present all steel industries are all being considered the energy-saving and cost-reducing efficient of putting forward, machinery is all developing to high speed, high efficiency, for adapting to this high speed steel rolling, swivel joint is all being adopted basically in countries in the world on sheet material uncoiling, the expansion mechanism that batches, this device advantage of being furnished with swivel joint is to reduce equipment occupation space, improve service life of equipment and be convenient to maintenance management, current at a high speed, high pressure (500～1000r/min be equivalent to mill speed 10～40m/s, more than the 15Mpa) future development.The shortcomings such as batch at present, the hydraulic rotary joint on the harmomegathus oil cylinder of uncoiling exists low-pressure, the slow-speed of revolution, running torque are large, easily large, continuous operation when easily heating can not be grown of fault, leakage rate, life-span are short at iron and steel, can not adapt to high pressure, the high speed of a motor vehicle, low torque at all, lowly leak, the usage requirement of long-life.

Summary of the invention

The utility model is for above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, can adapt to high speed, high pressure, low torque, low leakage, high-voltage high-speed formula swivel joint that the self-heating amount is low.

The technical solution of the utility model is: high-voltage high-speed formula swivel joint, comprise: running shaft 1, transparent cover 2, outside framework oil seal 3, shaft block ring 4, conical bearing 5, housing I section 6, housing II section 7, auxiliary seal 8, wavy spring 9, lock washer 10, round nut 11, the blind lid 12 of spline, long spiro nail 13, Teflon seal ring 14, positioning disk 15, it is characterized in that: described auxiliary seal 8 is contained on the Teflon seal ring 14 in advance, Teflon seal ring 14 is contained in respectively housing I section 6 left position, the neutral position of housing II section 7 location right and housing I section 6 and housing II section 7, positioning disk 15 is screwed the left side that is connected to housing I section 6 and the right of housing II section 7, outside framework oil seal 3 transparent cover 2 of packing into, transparent cover 2 is inserted in axle 1, shaft block ring 4 is contained on the axle 1, conical bearing 5 is contained between housing I section 6 and axle 1 external diameter, axle 1 is packed on the housing I section 6, housing II section 7 is inserted on the axle 1, bearing 5 is contained between housing II section and axle 1 external diameter, successively at axle 1 wavy spring 9 of packing into, lock washer 10, round nut 11, the blind lid 12 of spline, by long spiro nail 13 with housing I section 6, the blind lid 12 of housing II section 7 splines is connected, and with screw transparent cover 2 and housing I section 6 is linked into an integrated entity.

Further, the whole material of described high-voltage high-speed formula swivel joint is measuring instrument steel.

The utility model advantageous effect: simple in structure, to adapt to high speed, high pressure, low torque, low leakage, self-heating amount low, 1000 rev/mins of maximum speeds of the present utility model, maximum pressure 22MPa, the media such as applicable hydraulic oil, glycerine.
