Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with specific embodiment to this
Invention is further elaborated.
As shown in Figure 1, 2, a kind of multi-function coupling, including shell 1, shell is cylindric.Shell 1 therein is equipped with bottom
11.Inner core 2 is equipped in shell 1, inner core 2 is made using aluminium material.
The shape of above-mentioned inner core 2 is upper and lower narrow, intermediate wide cylindrical shape, and bottom 11, inner core are close in 2 lower end of inner core
2 are located at 1 center of shell.The present embodiment focuses on interference filled rubber 3 between inner core 2 and shell 1, the rubber 3 with it is interior
2 bonding by Vulcanization of core possesses the transmitting of super large torsion.It is filled using interference, adjusts rubber damping according to requirements and magnitude of interference is true
Protect the normal use of shaft coupling.
Upper cover 12 is mounted in the upper end of shell 1, and the edge of the upper cover 12 is fixed on shell 1, in the upper cover 12
The heart is close to inner core 2, and splined shaft 4 is installed in inner core 2, and splined shaft 4 passes through inner core 2.Above-mentioned upper cover 12 includes intermediate rotary table 121
With the benchboard 122 at edge, 122 edge of benchboard is fixed on the inner surface of shell 1.The top edge of shell 1 is equipped with outside
The skirt 13 of extension.Skirt 13 is conducive to fixed and connects.
Above-mentioned 3 upper end of rubber is close to benchboard 122, and bottom is close in the lower end of rubber 3, and rubber 3 uses above-mentioned knot
Structure can save materials, realize biggish elastic torque space.The rubber volume being pressed between inner core and shell is rubber itself
The 50% of volume.
The present embodiment uses Rubber Media, and reduction vibration and noise can be played in torsion transmittance process, can lean on rubber
Frictional force between glue expansion and shell carries out the transmitting of torsion.The present embodiment installs a upper cover 12 additional, can make inner core 2 outside
It is not fallen out under any circumstance in shell 1.Inner core is made using aluminium material, rather than steel, in the operating that overloads, makes inner core
Spline can also damage, while also function to defencive function, duplicate protection.
It referring to figs 1 and 3, is the use state of the present embodiment.
It is equipped with bolt hole on the skirt of shell 1 13, is coupled by bolt with the flywheel 5 of power input equipment, splined shaft 4
It across inner core 2 and is fixed in upper cover 12, splined shaft 4 passes through shaft coupling and is fastened on universal shaft 6, and universal shaft 6 is another
End installation connection propeller 7.Spiral pitch regulator 8 can be installed on the bearing of propeller 7, for adjusting revolving speed.
Couple above by middle spline shaft 4 and propeller 7.Behind shaft coupling used propeller 7 occur admittedly hinder or
Propeller 7 encounter in water water plant, fishnet etc. winding resistance rise, when meeting or exceeding rubber and housing frictional forces, rubber 3 with
Slide displacement is generated between shell 1.Displacement causes rubber 3 and shell 1 to generate acute friction to damaging, and transmits power interruption, from
And power input equipment is protected not to be damaged.Furthermore the bolt for only needing to remove on flywheel 5 after shaft coupling damage can quickly more
It changes, repairs extremely convenient.
Related data: shell 1, inner core 2, rubber 3 static stress analysis
Table 1
2 example attribute of table
3 material properties of table
