Problems solved by technology
[0002] In reciprocating equipment, oil leakage at the coupling rod is very common, and with the wear of seals such as oil seals, the oil leakage becomes more serious. The processing accuracy and installation of original parts, and the wear of moving parts of the equipment have further caused seals It is not concentric with the connecting rod, the eccentric wear is more serious, and the seal cannot be adjusted, and it is labor-consuming and time-consuming to replace the seal

Embodiment Construction
[0014] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0015] Examples of the present invention figure 1 As shown, the reciprocating fully floating sealing structure includes sealing box 1, butterfly nut 2, stud 3, hex head bolt 4, sealing sleeve 5, sealing element 6, spacer ring 7, baffle plate 8, O-ring (gasket ) 9. The connecting rod 10, the sealing sleeve 5 are filled with the sealing member 6 and the spacer ring 7, the baffle plate 8 is installed, and the bolts are tightened to form a whole; the sealing box 1 is installed first, and then the sealing sleeve (with the sealing member) is integrated into the joint Connect the rod to the contact surface of the sealing box, and gently put on the wing nut 2. The inner hole of the sealing box at 101 is 2-3mm larger than the outer diameter of the sealing sleeve, so that u...

The invention relates to a full-floating seal structure for reciprocating. A seal box and a seal sleeve are split, the seal sleeve is made of nonmetal, the upper portion and the lower portion of the seal sleeve are each provided with an air hole and an oil leak hole, two seal pieces are installed in the seal sleeve, a spacer ring with an annular groove and six uniformly-distributed holes is additionally installed between the seal pieces, and the seal pieces and the spacer ring are fixed by a baffle to form a whole. The size of the outer ring of the seal sleeve is two-three millimeters smaller than that of the seal box, in addition, the size of a seal sleeve fixing double-screw bolt hole is three millimeters larger than that of a double-screw bolt, so that a seal sleeve component is installed in a linking rod, an inner hole is located automatically, a butterfly nut is closed but not screwed, barring is performed to enable the seal sleeve to do reciprocating motion with a middle rod to center automatically, then the butterfly nut is screwed manually, the seal sleeve is fixed, and the seal sleeve and the seal box are sealed by use of an O-type ring or a pad. Meanwhile, after equipment runs for a certain time, the butterfly nut is unscrewed, and the seal sleeve can be adjusted again. By the adoption of the structure, disassembly and assembly are convenient, the labor intensity is greatly relieved, the seal effect is good, and the oil saving effect is obvious.
Description
technical field [0001] The invention relates to the field of sealing structures, in particular to a reciprocating fully floating sealing structure. Background technique [0002] In reciprocating equipment, oil leakage at the connecting rod is very common, and with the wear of seals such as oil seals, the oil leakage becomes more serious. The processing accuracy and installation of original parts and the wear of moving parts of the equipment have caused more damage to the seals. It is not concentric with the connecting rod, the eccentric wear is more serious, and the seal cannot be adjusted, and it is labor-intensive and time-consuming to replace the seal. Contents of the invention [0003] The technical problem to be solved by the embodiments of the present invention is to provide a reciprocating fully floating seal that can be adjusted at any time to adapt to the running-in and wear of moving parts, and to avoid the problem of oil leakage caused by the reciprocating joint...
