Technical field
The utility model belongs to milling equipment technical field, especially relates to a kind of boss casing connecting structure.
Background technology
The axle head of milling train gateway pinch roll is all generally connect a flange sleeve by flat key, and this flange sleeve is connected with a Hooks coupling universal coupling, transmits power to pinch roll.Intrinsic Hooks coupling universal coupling due to installation site bad, pendulum angle is larger, and make flange sleeve be subject to axial force comparatively large, often can come off, cause fault, impact is produced.
Utility model content
Problem to be solved in the utility model is to provide a kind of boss casing connecting structure, utilizes the ring flange mounting flange cover being threaded in pinch roll, overcomes the axial force that flange sleeve is subject to, stopped the generation of flange sleeve release failure.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of boss casing connecting structure, comprises the flange sleeve that roll body and roll body are arranged; Described roll body comprises the first linkage section and second linkage section of coaxial setting; Described flange sleeve is connected with the second linkage section of described roll body by connecting key; First linkage section of described roll body is provided with ring flange; Shown ring flange is fixedly connected with flange sleeve.
Further, the diameter of described first linkage section 5 ~ 10mm larger than the diameter of the second linkage section.
Further, described first linkage section is in the one end near the second linkage section on roll body.
Further, the length of described flange sleeve 2 ~ 5mm larger than the length of the second linkage section.
Further, described first linkage section has external thread structure, and described ring flange is provided with associated internal thread.
Further, the external thread length of described first linkage section is 30mm.
Further, the thickness of described ring flange is 20mm.
Further, described first linkage section is provided with chamfering near one end of the second linkage section.
Further, described ring flange and described flange sleeve are bolted to connection.
Further, described flange sleeve and described ring flange are coaxially arranged, and the external diameter of the two is equal.
The advantage that the utility model has and good effect are:
1) utilize the ring flange being threaded in pinch roll to fix flange sleeve, overcome the axial force that flange sleeve is subject to, thoroughly stop the generation of flange sleeve release failure.
2) flange sleeve is against on the shaft shoulder that formed between the second linkage section and the first linkage section, connects more solid and reliable, without rigging error.
3) ring flange is threaded with the first linkage section, and ring flange is fixedly connected with flange sleeve bolt, assembling and convenient disassembly, is easy to processing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-roll body; 2-flange sleeve; 3-first linkage section; 4-second linkage section; 5-connecting key; 6-ring flange; 7-bolt.
Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
A kind of boss casing connecting structure, as shown in Figure 1, comprises the flange sleeve 2 that roll body 1 and roll body 1 are arranged; Described roll body 1 comprises coaxial the first linkage section 3 and the second linkage section 4 arranged; Described flange sleeve 2 is connected with the second linkage section 4 of described roll body 1 by connecting key 5; First linkage section 3 of described roll body 1 is provided with ring flange 6; Shown ring flange 6 is fixedly connected with flange sleeve 2.
It should be noted that, flange sleeve 2 is provided with the connecting hole be connected with outside Hooks coupling universal coupling, is conveniently connected and fixed.
Wherein, the diameter 5 ~ 10mm larger than the diameter of the second linkage section 4 of described first linkage section 3, described first linkage section 3 is in the one end near the second linkage section 4 on roll body 1.Form ladder shaft-like structure, flange sleeve 2 is against on the shaft shoulder that formed between the second linkage section 4 and the first linkage section 3, connects more solid and reliable, without rigging error.
Wherein, the length of described flange sleeve 22 ~ 5mm larger than the length of the second linkage section 4.Therefore, the second linkage section 4 can not stretch out outside flange sleeve 2, avoids interfering with other parts of outside.
It should be noted that, connecting key 5 is flat key preferably.The preferred 20mm of thickness of ring flange 6, mates with overall structure size, enough ensures bonding strength, can sustain the axial force of flange sleeve 2 completely.
Wherein, described first linkage section 3 has external thread structure, and described ring flange 6 is provided with associated internal thread, is threaded solid and reliable, assembling and convenient disassembly.
Wherein, the external thread length of described first linkage section 3 is 30mm.The screw thread of described first linkage section 3 is the external screw thread of M80x2.Choose the conventional pitch of threaded engagement, structural strength is good, is easy to processing, also convenient for assembly.
Wherein, described first linkage section 3 is provided with chamfering near one end of the second linkage section 4, can not scratch when assembly flange dish 6 and flange sleeve 2.
Wherein, described ring flange 6 is fixedly connected with by bolt 7 with described flange sleeve 2, stable connection, meanwhile, and assembling and convenient disassembly.
Wherein, described flange sleeve 2 and described ring flange 6 are coaxially arranged, and the external diameter of the two is equal, like this, appearance profile consistent size, can not occur to estimate less than interference situation.
It should be noted that, ring flange 6 and flange sleeve 2 are all offer fixing hole along the axis of respective flange, and bolt 7 pierces in the two corresponding fixing hole simultaneously and is fixed.
During assembling, the first linkage section 3 first ring flange 6 being screwed in roll body 1 is fixed, then connecting key 5 is arranged on the keyway of roll body 1 second linkage section 4, be loaded on flange sleeve 6, flange sleeve 6 is connected with the second linkage section 4 by connecting key 5, finally, passes in the connecting hole of ring flange 6 and flange sleeve 2 correspondence with bolt 7 simultaneously, load onto nut screwing clamping, fix ring flange 6 and flange sleeve 2.
The utility model utilizes the ring flange 6 being threaded in pinch roll to fix flange sleeve 2, overcomes the axial force that flange sleeve 2 is subject to, thoroughly stops the generation of flange sleeve 2 release failure.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
