Abstract
The utility model relates to a hindrance-free rotary joint, which is used for continuously cooling rollers in a rotary state, and comprises a cooling medium inlet pipe (1), a shell (2), a bolt (3), a bearing block (4), a thrust bearing (5), a locking nut (6), a shaft (7), an inner rotary sleeve (8), a sealing ring (9), a rolling piece (10), a fixed block (11), a flange (12), a cooling medium output pipe (13), a plug (14) and an oil injection nozzle (15). The hindrance-free rotary joint is not affected by cooling media, operating temperature and operating pressure, and has less abrasion and long service life.
Description
(1) technical field
The utility model relates to a kind of without hindrance formula swivel joint, is used for the continuous cooling of roller under rotation status.
(2) background technique
In process hides; papermaking; weaving; industries such as metallurgy; running into roller through regular meeting need be in the problem of the continuous cooling under the rotation status; substantially all adopt swivel joint to solve; swivel joint mainly contains the H type at present; the Q type; the TX type; structural types such as YJ type; it is little that they have a volume; in light weight; characteristics such as friction torque is little; but; structurally all there is common deficiency in they; for example: the gap between intake pipe and the outlet pipe is too small; when turbidity test too high when the basicity of cooling medium or medium are bad; the dirt blocking phenomenon takes place easily, directly influences cooling effect.In addition, the structural type of these swivel joints, its inner body, Sealing all directly contact with cooling medium, part lost efficacy because of corrosion easily, simultaneously, Sealing produces water clock, turnover medium crossfire phenomenon etc. also easily because of the influence of cooling medium turbidity test damages.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and not influenced by cooling medium, operating temperature, working pressure and wear and tear without hindrance formula swivel joint little, long service life.
The purpose of this utility model is achieved in that a kind of without hindrance formula swivel joint, described joint includes the cooling medium inlet pipe, housing, bolt, bearing support, thrust-bearing, locking nut, axle, cover in the rotation, seal ring, rolling element, fixed block, flange, cooling medium goes out pipe, block and pump nozzle, described bearing support links to each other with housing by bolt, described thrust-bearing is installed in the bearing hole of bearing support, described locking nut is spun on the axle, and locking nut is pressed on thrust-bearing in the bearing hole of bearing support, described cooling medium inlet pipe and cooling medium go out pipe and are connected to the housing two ends, cover is installed in the housing in the described rotation, cover one end shutoff has axle in the described rotation, the other end is connected with interior pipe, described ring set puts in rotation, between described rolling element is positioned over and overlaps in housing and the rotation, have putting hole with rolling element opposite position place on the described housing, described blocking is plugged in this putting hole, described pump nozzle is installed on the housing, described fixed block is connected on the housing outer wall, have an annular chute with cooling medium inlet pipe corresponding section on the described rotation outer wall of inside race, have some cooling mediums on the described chute and enter the hole, go out to manage the corresponding section with cooling medium on the described rotation outer wall of inside race and have an annular cooling medium cavity, cover is fixed in housing on the roller by flange in the described rotation, has some cooling mediums with annular cooling medium cavity corresponding section on the described flange and portals.
The beneficial effects of the utility model are:
When the motivational drive roller rotates, transfer torque in the rotation and put by being connected bolt on the roller, simultaneously, also transfer torque on rolling element and axle and the thrust-bearing, rolling element is rolled in raceway, thrust-bearing and axle are along with roller together rotates, can reduce the moment of torsion transmission between the cover in housing and the rotation greatly by rolling element and thrust-bearing, therefore the moment of torsion that is delivered to housing is very little, then, fixed block is fastened on a certain immovable point, makes housing be in stationary state, overcome the surface friction drag that this part moment of torsion brings, thus be implemented in continuous under the rotation status cool off purpose.Crossfire or leakage phenomenon appear in real work for fear of cooling medium, the empty both sides of the cooling medium of cover turnover in rotation, and the end of housing, seal ring has been installed respectively, in order to reduce rolling element surface friction drag, alleviate the wearing and tearing of rolling element and raceway, pump nozzle has been installed on housing, prolong the working life of swivel joint with this.
