Description
Technical field
The utility model relates to torque limited technical field, especially relates to a kind of Novel steel ball limited torque device.
Background technique
In mechanical transmission; the mechanical accident such as working equipment damage, burn-down of electric motor that frequent appearance occurs because of overload; its main cause is in the transmission device between prime mover and working equipment; there is no protective gear; though or have protective gear; but it is poor to the reacting condition sensitivity of moment of torsion, than protected parts, actuation time occurs that the time of damaging is long.Steel ball limited torque device is used for accurately limiting the moment of torsion transmitted, and when moment of torsion exceedes a certain limit value, steel ball limited torque device can be thrown off in time and shielded; When moment of torsion does not exceed limit value, it is with being equivalent to common pin.Limited torque device comprises shears pin, friction disk type and steel ball type etc.Shear the impact that pin limited torque device gathers way by accuracy of manufacturing, material homogeneity and load, during overload, precision is not high, in addition, due to fatigue damage accumulation, the intensity of element own also reduces along with the increase of operating time, and after pin is cut off, need again to change pin, resume production and need the long period.Friction type limited torque device affects by stable friction factor, and operation precision is not high yet, when often transshipping, affects frictional behaviour and intensity because friction plate easily generates heat, and effect is not good.
Model utility content
For overcoming the problems referred to above, the utility model adopts following technological scheme:
A kind of Novel steel ball limited torque device, comprise left half flange, right half flange, left half flange and right half flange are embedded in groove cover by big steel ball and realize connecting, and big steel ball is positioned at a steel ball sleeve braked by push rod, and push rod both sides are provided with pretension pressure ring, pretension pressure ring presses catch ring by spring, external application set casing is fixed, and is provided with extruding steel ball after catch ring, is placed in set casing inside you, be provided with inclined-plane ring after extruding steel ball, be placed in inside set casing.
Described set casing is convex shape.
Described catch ring and inclined-plane annular angled.
The utility model has the advantages that: square reaction sensitivity is high; action is accurate; rapidly, precision is high, reliable operation; effectively can limit the moment of torsion between prime mover and working equipment; can throw off the moment of torsion that prime mover transmits when ensureing apparatus overload in time, proterctive equipment does not damage, and reduces mechanical accident; can resume production in a short period of time again, be applicable to need accurately to limit in the mechanical transmission of transmitting torque completely.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model equipment.
Embodiment
As shown in Figure 1, a kind of Novel steel ball limited torque device, comprise left half flange 1, right half flange 12, left half flange 1 and right half flange 12 are embedded in groove cover 2 by big steel ball 3 and realize connecting, big steel ball 3 is positioned at a steel ball sleeve 4 braked by push rod 5, push rod 5 both sides are provided with pretension pressure ring 6, pretension pressure ring 6 presses catch ring 9 by spring 7, external application set casing 8 is fixed, extruding steel ball 10 is provided with after catch ring 9, be placed in set casing you inside 8, inclined-plane ring 11 is provided with after extruding steel ball 10, be placed in inside set casing 8, described set casing 8 is in convex shape, described catch ring 9 and inclined-plane ring 11 form several angle.
During normal operation, left half flange 1 and right half flange 12 are embedded in groove cover 2 by big steel ball 3 and realize being connected, big steel ball 3 is positioned at a steel ball sleeve 4 by push rod 5 stop, the stopping power of push rod 5 pairs of big steel balls 3 comes from spring 7 and extrudes effect to a circle extruding steel ball 10 after catch ring 9, catch ring 9 and inclined-plane ring 11 are all the inclined-plane rings having several angle, two inclined-planes to a circle extruding steel ball 10 angulation extruding, thus produce the power of a circle extruding steel ball 10 pairs of push rods 5.Pretension pressure ring 6 is used to the impacting force adjusting spring 7 pairs of catch rings 9, and the impacting force of spring 7 pairs of catch rings 9 determines this device can the size of transmitting torque.
When there being overload, the conical surface being fixed on the groove cover 2 on left half flange 1 can produce a larger active force to big steel ball 3, when this active force is greater than the stopping power of push rod 5 pairs of big steel balls 3, big steel ball 3 can deviate from groove cover 2, left half flange 1 and right half flange 2 is made to produce relative movement, in turn big steel ball 3 promotes push rod 5 and extrudes a circle extruding steel ball 10, extruding steel ball 10, overcome the impacting force of spring 7 pairs of catch rings 9 simultaneously, thus make a circle extruding steel ball 10 moving radially along push rod 5, at this moment, big steel ball 3 and push rod 5 deviate from groove cover 2 at steel ball sleeve 4 and move, after big steel ball 3 departs from the conical surface of groove cover 2 completely, big steel ball 3 can be still in steel ball sleeve 4, once reach this situation, left half flange 1 and right half flange 12 will rotate completely freely.
After overload is got rid of, need to recover this device to normal state, as long as now rearrange the position of left half flange 1 and right half flange 12, the center making groove overlap 2 centers and big steel ball 3 remains on same center line, push rod 5 afterbody be exposed at outside set casing 8 is knocked with a rubber hammer, make a circle extruding steel ball 10 get back to initial position, and big steel ball 3 is embedded in groove cover 2.
