Abstract
The invention relates to a flexible bolt connecting structure. The flexible bolt connecting structure comprises a first component (1), a second component (2) and a bolt (5), wherein the first component (1) is connected with the second component (2) and through the bolt (5). The flexible bolt connecting structure further comprises an adjusting sleeve (3) and O-shaped rubber sealing rings (4), annular grooves are formed in the position, with a certain distance to two end opening, of the inner side of a bolt hole of the first component (1), the O-shaped rubber sealing rings (4) are installed in the annular grooves, and the adjusting sleeve (3) is installed between the first component (1) and the bolt (5) in a sleeved mode. The flexible bolt connecting structure can absorb energy transmitted by the bolt and can also change the natural vibration frequency of the bolt, a resonance region can be avoided, and therefore bending fatigue crack of the bolt can be prevented.
Description
Technical field
The invention belongs to bolt connection piece, be specifically related to a kind of flexible bolt linkage structure.
Background technique
At present for connection, the sealing of two and above mechanical parts, most with bolts.For flexible stay bolt, connect, mainly with bolt, by two, to be connected member directly to couple together at present, advantage is that number of spare parts is few, simple in structure, deficiency is that bolt is under the vibrational excitation of certain frequency, may cause bolt high frequency chatter, thereby cause additional flexural load, cause bolt crooked fatigue fracture.Therefore Member Reliability Analysis is poor.
Summary of the invention
The present invention is exactly, in order solving in prior art under certain excitation and chatter, to cause the problem of the fatigue fracture of bolt, and a kind of flexible bolt linkage structure is provided.
The technical solution used in the present invention: a kind of flexible bolt linkage structure, it comprises the first member 1, second component 2, bolt 5, the first member 1 is connected by bolt 5 with second component 2, also comprise adjusting sleeve 3 and O type rubber seal 4, the first member 1 offers respectively circular groove in bolt hole inner distance two-port a distance, O type rubber seal 4 is installed in described circular groove, and adjusting sleeve 3 is sleeved between the first member 1 and bolt 5.
Further, interference fit between adjusting sleeve 3 and the first member 1, magnitude of interference is 0.05mm～0.15mm.
Further, described circular groove is 8～18mm in the distance apart from two-port place.
The present invention compared with prior art its beneficial effect is: what this structure was applicable to adopt on light alloy (aluminium, magnesium etc.), coloured, ferrous metal member is threaded, screw pair connects load can reach high-strength bolt (more than 10.9 grades) the more than 70% of yield limit, and has repeated disassembled and assembled and do not damage the maintainalbility feature of bolt; This Placement is simple in structure, easy accessibility, and the maintenance of parts and components is good, in the working life that is conducive to improve connected piece, has improved the reliability that has seal request link simultaneously; And improved the manufacturability of parts machining and assembling, reduced manufacture cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
