Limitation.
Big flexible, retractable shaft coupling includes three parts：Drive end, coupling part, adjustment end, drive end is by drive sleeve A1
Constitute, adjustment end is made up of drive sleeve B3, and coupling part is made up of middle contiguous block 2, as shown in Figure 1.Drive sleeve A1 and transmission
Set B3 has interchangeability, both can be as drive end, also can be used as adjustment end.
Due to the interchangeability of drive sleeve A1 and drive sleeve B3, both are in structure consistent, here only with drive sleeve A1
As a example by carry out introduction about the construction.As shown in Fig. 2 drive sleeve A1 is forked in cylinder, 4/5ths of circumference is radially cut, form wide
The gap A5 for 0.2mm is spent, drive sleeve A1 is divided in the axial direction be two sections, and one end is fork-shaped driving end 4, and the other end is cylinder
Shape locking end 8, locking end cuts the gap B7 that an a width of 1.5mm, depth are 3/4ths diameters, gap B7 and gap vertically
A5 is mutually perpendicular to, and gap B7 is cut through to gap A5, respectively gap A5, and in gap, the symmetrical both sides of B7 are drilled with screwed hole 6 and rank
Terraced through hole 10, screwed hole 6 and ladder hole 10 with one heart, when in power transmission shaft insertion locking hole 9, can insert ladder with fillister head screw
In through hole 10 and it is threaded into hole 6, makes the tubular locking end 8 of drive sleeve A1 that micro-strain to occur, now the spacing of gap B7
Diminish, locking hole 9 holds power transmission shaft tightly, it is ensured that relative slip will not occur in transmission process, so as to deliver moment of torsion.Centre connects
The rectangular shape of block 2 is connect, drive sleeve A1 and drive sleeve B3 is stuck in the orthogonal plane of middle contiguous block 2.The course of work
In, the drive sleeve A1 of drive end passes to middle contiguous block 2 by fork-shaped driving end 4, contiguous block 2 further through drive sleeve B3 fork
Shape driving end 4 passes to adjustment end, realizes the transmission of moment of torsion.
The operation principle of big flexible, retractable shaft coupling：
Shaft coupling assemble method in itself is fairly simple, it is only necessary to the fork-shaped driving end of drive sleeve A1 and drive sleeve B3
4 are stuck in the orthogonal plane of middle contiguous block 2, without mode connects for screw, as shown in Figure 3.The shaft coupling two ends and biography
The connection of moving axis is in the ladder hole 10 of drive sleeve A1 and drive sleeve B3 and to be threaded into hole by the way that fillister head screw is inserted
6, make the tubular locking end 8 of drive sleeve A1 and drive sleeve B3 that micro-strain to occur, so that 9 armfuls of the locking hole at the shaft coupling two ends
Tight power transmission shaft.
Drive sleeve A1 can have the linear relative movement along Y-axis and Z axis with middle contiguous block 2 in the case where not deviating from mutually
And the relative rotary motion around X-axis in the range of certain angle, drive sleeve B3 is with middle contiguous block 2 in the feelings do not deviate from mutually
Can there are relative linear displacement along Y-axis and X-axis and the about the z axis relative rotary motion in the range of certain angle under condition.
In the big flexible, retractable shaft coupling course of work, the shaft coupling can adjust deviation as shown in Figure 4, Figure 5 and Figure 6,
Reachable ± the 2mm of axial deviation adjusted value, the reachable ± 2.5mm of radial missing adjusted value, reachable ± 5 ° of tilting tolerance adjusted value.Therefore
The shaft coupling relative to the existing shaft coupling of in the market except there is a larger flexibility, also larger retractility, satisfaction need compared with
The working condition requirement of big flexible and certain retractility.
The utility model has larger adjusted value in terms of radial missing and tilting tolerance is ensured, i.e., existing relative in the market
Shaft coupling have bigger flexibility, while novelty make shaft coupling axially having certain retractility, make up shaft coupling and exist
The deficiency of axially adjustable aspect；The coupler structure is simple, transmitting accuracy is high, convenient for installation and maintenance, with low cost.
While there has been shown and described that embodiment of the present utility model, it will be understood by those skilled in the art that：
In the case where principle of the present utility model and objective is not departed from various changes, modification, replacement can be carried out to these embodiments
And modification, scope of the present utility model limits by claim and its equivalent.
