Description
Technical field
The utility model belongs to pipeline connection technology field, relates to a kind of mechanical seal swivel joint that can improve radiating efficiency simple in structure, easy to use.
Background technology
The purposes of coiling machine is to collect overlength rolled piece, is wound into volume so that produce, transport and store. Coiling machine is the important auxiliary equipment of mill, is indispensable equipment in the main rolling line of coil rolling, in band and wire production, is all widely used. Reel is mainly made up of fanning strip, spool shaft, slide block, pull bar, expanding cylinder, swivel joint etc. The breathing of reel drives spool shaft by contract cylinder, by breathing winding machine. The pressure of swivel joint and rotating speed define the rotary speed of push-pull effort and the spool of contract cylinder. High pressure, high-revolving swivel joint can effectively improve the operating efficiency of coiling machine. Domestic high pressure, high-speed joint are all monopolized by foreign manufacturer substantially, and domestic enterprise is because the problems such as the heat radiation of swivel joint are not yet developed practical high pressure, high-speed joint. The nearlyer research and development that carry out high-speed joint and application are important research directions of domestic milling equipment manufacturer, if can develop smoothly high pressure, high-revolving swivel joint and can effectively should have, the operating efficiency that will effectively improve coiling machine, reaches domestically leading level. Therefore, research and develop a kind of mechanical seal swivel joint that can improve radiating efficiency extremely important.
Summary of the invention
The purpose of this utility model is to provide a kind of mechanical seal swivel joint that can improve radiating efficiency simple in structure, easy to use.
The purpose of this utility model is to realize like this, comprise rotating shaft and housing, described housing is set to tubular structure, described inner walls coordinates with rotating shaft rotation, and hydraulic fluid port is radially set on described housing, and oil circuit is set in described rotating shaft vertically, the interface of oil circuit is radially set on the surface of described rotating shaft, the setting corresponding with hydraulic fluid port of the interface of described oil circuit, the both ends inwall of described housing arranges bearing and is connected with rotating shaft, and the two ends of described housing arrange end cap; Described housing and rotating shaft matched in clearance; Draining passage is also set on described housing, and the branch road of described draining passage is connection bearing place and rotating shaft outside wall surface respectively.
Between the housing of the utility model swivel joint and rotating shaft, adopt mechanical seal structure, make can adapt to higher relative rotation speed between housing and rotating shaft. Between the housing of swivel joint and rotating shaft, have certain gap, allow certain leakage rate, under higher rotating speed, between housing and rotating shaft, can produce larger heat, the oil of leakage can be taken away some heats, thereby improves overall thermal diffusivity. Between housing and rotating shaft, be by mechanical seal, contact is unavoidable, so adopt different materials, has suitable nonhomogeneous hardness, possesses certain wearability, good heat radiation, thereby the service life of guarantee swivel joint. Rotary joint structure is simple, compact, balance is good, thereby reduces the various adverse effects that High Rotation Speed brings.
