Abstract

The utility model provides an air cooling rotating joint which is capable of improving the radiating condition of the rotating joint to achieve the aim of prolonging the service life on the premise of not adding a water cooling device. The air cooling rotating joint comprises a shell, wherein the right end of the shell is connected with a hollow shaft, the upper part of the shell is provided with a lubricating nipple, the periphery of the right part of the shell is provided with radiating fins which are parallel with the axial lead of the shell, a casing pipe is sleeved on the hollow shaft and is connected with the hollow shaft through a set screw and a flat key, the periphery of the casing pipe is provided with a cooling fan, the left end of the casing pipe is fixedly connected with awind-proof cover, and the wind-proof cover corresponds to the right end of the shell.

Description

Air-cooled swivel joint

Technical field

The utility model relates to a kind of rotating sealing device, relates in particular to a kind of air-cooled swivel joint.

Background technique

At present swivel joint extensively uses in industrial production, effect be fixing tube to rotation, or the auxiliary seal of the equipment fed sheet of a media of reciprocally swinging (water, gas, wet goods).In high speed (400-2000 rev/min), medium is in the compressed-air actuated swivel joint operating mode (as pneumatic clutch).What use is the structure the same with the swivel joint of water flowing, and by the housing hollow shaft, bearing and mechanical sealing part are grouped into (as shown in Figure 1).Because the medium poor cooling performance causes bearing and sealing surface place temperature too high.General mechanical seal will add water cooling plant usually when high temperature and high speed.But in swivel joint uses, owing to be subjected to conditionality such as space, generally all do not have this device, cause swivel joint short working life.

Summary of the invention

The purpose of this utility model provides a kind of under the prerequisite that does not increase water cooling plant, and the radiating condition that can improve swivel joint reaches the air-cooled swivel joint that increases the purpose in working life.

For achieving the above object, the technical solution adopted in the utility model is: a kind of air-cooled swivel joint, comprise housing, and the housing right-hand member is connected with hollow shaft, housing top has oil nozzle, it is characterized in that: design has the heat radiation wing on the right part periphery of housing, and heat radiation wing and housing axis parallel are with sleeve pipe on the hollow shaft, be connected with flat key by set screw between sleeve pipe and the hollow shaft, the sleeve pipe periphery has radiation fan, and the sleeve pipe left end is fixedly connected with storm shutter, and storm shutter is corresponding with the right-hand member of housing.

The utility model has the advantages of and be: because design has the heat radiation wing on the right part periphery of the utility model middle shell, be with sleeve pipe on the hollow shaft, be connected between sleeve pipe and the hollow shaft, the sleeve pipe periphery has radiation fan, the sleeve pipe left end is fixedly connected with storm shutter, so use the utility model can increase heat diffusion area, utilize hollow shaft to rotate the increase air velocity at a high speed, arrive the purpose of accelerating heat radiation, fan blows on the housing that has the wing that dispels the heat, the heat that swivel joint is produced because of spin friction accelerates to reduce good heat dissipation effect.
