Abstract
The invention discloses an overload protection type coupling. When the coupling works in an overladen way, a steel ball is pressed into an opposite through hole, a left connecting sleeve and a right connecting sleeve rotate opposite to each other; when power is transmitted, the coupling doubles as overload protection, therefore, the overload protection type coupling effectively overcomes the defects that the traditional coupling only has single function and an overload protection device is required to be additionally installed in a mechanical transmission system. The overload protection type coupling has the advantages of simple equipment structure, low cost and great reduction of fault rate.
Description
Technical field
The present invention relates to a kind of protection coupling, refer in particular to a kind of overload protection formula coupling.
Background technique
At present, existing coupling mainly plays the effect that couples together between two transmission systems, and its function is general more single; Between the actual transmission system,, in powerdriven process, tend to take place the overload situation owing to receive the influence of other factors; In order to prevent since the generation of overload situation to the damage of transmission system, generally need be in the middle of transmission system the corresponding safety protection device of series connection, so not only can make the complex structure of equipment; Cost is higher; Simultaneously, because structure is comparatively complicated, rate of breakdown is raise.
Summary of the invention
For overcoming existing coupling because function singleness; In machine driven system, overload protection arrangement need be installed separately; And the defective that the device structure that causes therefrom is complicated, cost is higher, rate of fault is higher, the invention provides a kind of coupling with overload protection function.
The technical solution adopted for the present invention to solve the technical problems is: this overload protection formula coupling comprises left connecting sleeve, plane bearing, steel ball, butterfly spring, right connecting sleeve, fixed plate, double-screw bolt, adjusting bolt; This invention is provided with symmetrical left connecting sleeve and right connecting sleeve; The flange position of a left side connecting sleeve and right connecting sleeve is connected with a fixed plate through the plane bearing installation near, the flange of left connecting sleeve and right connecting sleeve respectively outside up and down relatively, fixes through double-screw bolt between each two fixed plate of both sides up and down; Be respectively arranged with steel ball up and down at left connecting sleeve and right connecting sleeve; On the flanged surface of said right connecting sleeve through hole is set, the outer end of through hole is provided with the adjusting bolt, in regulating the bolt end through hole; Be provided with butterfly spring, butterfly spring is fitted and is compressed steel ball; When operating overload; The steel ball back pressure is gone in the through hole on opposite, and left connecting sleeve and the corresponding rotation of right connecting sleeve make the present invention when transferring power; Have overload protective function concurrently; Can overcome existing coupling effectively because function singleness need be installed overload protection arrangement separately in machine driven system, and the defective that complex structure, cost are higher, rate of fault is higher of the equipment that causes therefrom.
Beneficial effect of the present invention: this overload protection formula coupling overcomes existing coupling function singleness effectively; And the defective of overload protection arrangement need be installed separately, and device structure is simple, cost is not high, greatly reduce rate of fault in machine driven system.
Description of drawings
Accompanying drawing 1 is a structure principle chart of the present invention.
As shown in the figure: 1. left connecting sleeve, 2. plane bearing, 3. steel ball, 4. butterfly spring, 5. right connecting sleeve, 6. fixed plate, 7. double-screw bolt, 8. regulate bolt.
Embodiment
In the drawings; The present invention includes left connecting sleeve 1, plane bearing 2, steel ball 3, butterfly spring 4, right connecting sleeve 5, fixed plate 6, double-screw bolt 7, regulate bolt 8, this invention is provided with symmetrical left connecting sleeve 1 and right connecting sleeve 5, the flange position of left connecting sleeve 1 and right connecting sleeve 5 relatively near; Left side connecting sleeve 1 is connected with a fixed plate 6 through plane bearing 2 installations respectively in the outside up and down with the flange of right connecting sleeve 5; Fixing between each two fixed plate 6 of both sides up and down through double-screw bolt 7, be respectively arranged with steel ball 3 at left connecting sleeve 1 up and down with right connecting sleeve 5, on the flanged surface of said right connecting sleeve 5 through hole is set; The outer end of through hole is provided with regulates bolt 8; In regulating bolt 8 end through holes, be provided with butterfly spring 4, butterfly spring 4 is fitted and is compressed steel ball 3; When operating overload; Steel ball 3 back pressures are gone in the through hole on opposite, and left connecting sleeve 1 and right connecting sleeve 5 corresponding rotations make the present invention when transferring power; Have overload protective function concurrently; Can overcome existing coupling effectively because function singleness need be installed overload protection arrangement separately in machine driven system, and the defective that complex structure, cost are higher, rate of fault is higher of the equipment that causes therefrom.
