Abstract
The invention relates to the technical field of rotary devices, in particular to a rotary joint on a crane. The rotary joint on the crane comprises a rotary shaft, a rotary seat and an end cover, the rotary shaft is arranged in the rotary seat, a liquid inlet pipeline is arranged in the rotary seat, an outer shell is arranged outside the rotary seat and is of a cuboid structure, a liquid inlet is formed in the side edge of the outer shell, the liquid inlet is communicated with the liquid inlet pipeline, the end cover is connected with the rotary shaft through a bolt, and the end cover is in a threaded step shape. According to the rotary joint, the mechanical balance characteristic of a high-quality sealing structure is achieved, the torque needed in the rotating process is quite low, and high sealing performance and high durability are achieved. The rotary joint is simple in structure and quite low in cost, and leakage is extremely less through precise machining.
Description
Technical field
The present invention relates to swivel gear technical field, especially a kind of for the swivel coupling on hoist.
Background technique
Swivel coupling is a kind of airtight rotation linker of 360 ° of rotation fed sheet of a media.That uses at present generally lacks the balance of machinery characteristic of high quality seal structure for the swivel coupling on hoist.During rotation, sealing is not high, and is not durable.For accurate machining, also have a small amount of leakage.
Summary of the invention
The technical problem to be solved in the present invention is: based on the problems referred to above, provide a kind of balance of machinery characteristic with high quality seal structure for the swivel coupling on hoist.
The technical solution adopted for the present invention to solve the technical problems is: a kind of for the swivel coupling on hoist, comprise turning axle, panoramatic head and end cap, described turning axle is arranged in panoramatic head, in described panoramatic head, be provided with input duct, described panoramatic head has shell outward, and shell is rectangular structure, the side of shell is provided with liquid entering hole, liquid entering hole is connected with above-mentioned input duct, and described end cap is connected with turning axle by bolt, and it is step-like that described end cap is screw thread.
Further, in such scheme, in described turning axle, be provided with the first interior threaded hole.
Further, in such scheme, in described end cap, be provided with the second interior threaded hole.
Further, in such scheme, described the first interior threaded hole is identical with the aperture of the second interior threaded hole, and the threaded line of the second interior threaded hole is the extension of the first interior threaded hole threaded line.
The invention has the beneficial effects as follows, the present invention has the balance of machinery characteristic of high quality seal structure, only requires very low moment during rotation, and has highly dense property and high durability.The present invention is simple in structure, and cost is lower, and accurate machining is seldom revealed.
