Abstract
The utility model discloses a rotating joint used for hydraulic pressure. The rotating joint comprises a joint body and a rotating shaft arranged in the joint body, bearings are arranged at two ends, between the joint body and the rotating shaft, of the joint body, the rotating shaft is fixed on inner races of the bearings, and sealing parts are arranged between the joint body and the rotating shaft as well as between the bearings. The rotating joint used for hydraulic pressure has the advantages that the two bearings are added on the end faces of two inner sides of an original rotating joint respectively, the rotating shaft is fixed on the inner races of the bearings, the rotating shaft is not stressed inside the rotating joint body by the aid of supporting points at the positions of the bearings when rotating, and thereby stress of the sealing parts mounted in the middle of the shaft is avoided, and service lives of the sealing parts are prolonged finally.
Description
Technical field
The utility model relates to a kind of swivel joint, specifically a kind of hydraulic pressure swivel joint.
Background technique
In continous way baking finish line, uncoiling machine, winder equipment are in service in 24 hours, in order to ensure that coil of strip is all the time in swelling state, continue to have pressure oil to provide therefore require mandrel to expand with oil cylinder, and pressure oil is carried by swivel joint.
Because uncoiling machine, winder equipment are in service in 24 hours, therefore swivel joint continues in operation in 24 hours and is to move under having pressure state.Swivel joint continuous service often can be in operation and occur inner seal wearing and tearing causing oil impregnate, oil leakage phenomenon, new Sealing reach the standard grade after working life only left and right one year, cause maintenance expenses higher, also cause the loss of hydraulic fluid leak.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of anti abrasive hydraulic pressure swivel joint.
In order to solve the problems of the technologies described above, the technical solution of the utility model is:
A kind of hydraulic pressure swivel joint, the running shaft that comprises joint body and arrange in joint body, at the two ends of described joint body, between joint body and running shaft, be provided with bearing, described running shaft is fixed on bearing inner race, between described bearing, between described bearing, between joint body and running shaft, be provided with Sealing.
At swivel joint end, described bearing installation place, described joint body, running shaft are the stepped of symmetry, form bearings mounted cavity; In bearing outside, on running shaft, be provided with the first baffle plate, on joint body, be provided with second baffle, described the first baffle plate blocks the inner ring of bearing, and described second baffle blocks the outer ring of bearing.
The utility model, at the each deep groove ball bearing that increases of the both sides, inside of former swivel joint end face, is fixed on running shaft on bearing inner race.In the time that running shaft rotates, rely on the strong point at bearing place, it is not had stressed in swivel joint body interior, avoid being arranged on the middle seal loading of axle, extend the working life of finally having realized Sealing.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, a kind of hydraulic pressure swivel joint, comprise joint body 1 and the running shaft 2 in joint body 1 interior setting, at the two ends of described joint body 1, between joint body 1 and running shaft 2, be provided with bearing 3, described bearing 3 adopts deep groove ball bearing, and described running shaft 2 is fixed on bearing 3 inner rings.
At swivel joint end, described bearing 3 installation places, described joint body 1, running shaft 2 are the stepped of symmetry, form the cavity that bearing 3 is installed; In bearing 3 outsides, on running shaft 2, be fixedly installed the first baffle plate 4 by bolt 7, on joint body 1, be fixedly installed second baffle 5 by bolt 7, described the first baffle plate 4 blocks the inner ring of bearing 3, and described second baffle 5 blocks the outer ring of bearing 3.
Between described bearing 3, between joint body 1 and running shaft 2, be provided with Sealing 6.In the time that running shaft 2 rotates, the strong point that relies on bearing 3 places, does not have it stressed in swivel joint body 1 inside, has avoided the Sealing 6 of setting between joint body 1 and running shaft 2 stressed, thereby avoided wearing and tearing, extend the working life of finally having realized Sealing 6.
Because joint body 1, running shaft 2 are the stepped of symmetry at joint body 1 tail end, under the stopping of bearing 3, running shaft 2 can not move to right vertically in joint body 1; Under the stopping of the first baffle plate 4, second baffle 5, running shaft 2 can not move to left vertically in joint body 1.
Above-described embodiment limits the utility model never in any form, and every employing is equal to replaces or technological scheme that the mode of equivalent transformation obtains all drops in protection domain of the present utility model.
Claims (2)
1. a hydraulic pressure swivel joint, the running shaft that comprises joint body and arrange in joint body, it is characterized in that: at the two ends of described joint body, between joint body and running shaft, be provided with bearing, described running shaft is fixed on bearing inner race, between described bearing, between joint body and running shaft, be provided with Sealing.
2. a kind of hydraulic pressure swivel joint according to claim 1, is characterized in that: at swivel joint end, and described bearing installation place, described joint body, running shaft are the stepped of symmetry, form bearings mounted cavity; In bearing outside, on running shaft, be provided with the first baffle plate, on joint body, be provided with second baffle, described the first baffle plate blocks the inner ring of bearing, and described second baffle blocks the outer ring of bearing.
