Abstract
The utility model relates to the technical field of mine crane mechanical equipment, in particular to a coupling used for an electric shovel hoisting machine and provided with a fixed internal expanding ring. The coupling comprises a coupling left shaft sleeve arranged on the output shaft of the electric shovel hoisting machine, a coupling right shaft sleeve plugged with the left shaft sleeve, an elastic rubber block arranged in the position where the coupling left shaft sleeve is plugged with the right shaft sleeve, and an internal expanding ring arranged in the coupling left shaft sleeve, and is characterized in that an end surface baffle is fixedly connected with the end of the internal expanding ring; and the end surface baffle is fixedly connected with the coupling left shaft sleeve through a bolt device, so as to ensure that the internal expanding ring is connected with the coupling left shaft sleeve into a whole body. The coupling has the advantages that the coupling can prevent the internal expanding ring from sliding and being worn, even vibration can not lead to falling off of the internal expanding ring, the changing frequency of the internal expanding ring component is reduced, the maintenance cycle of the electric shovel hoisting machine equipment is prolonged, and safety production is guaranteed.
Description
Technical field
The utility model relates to mine lifting equipment technical field, relates in particular to the coupling that is provided with fixing interior packing that a kind of power shovel winch is used.
Background technique
In bargh, the power shovel winch is a kind of equipment of using always, be used to wherein to control that the power shovel winch stops or the braking device that turning to is to be connected by the output shaft end of coupling with the power shovel winch, and the structural type of this coupling is: as shown in Figure 3, the sleeve end that is connected with the output shaft of power shovel winch evenly is provided with one group of groove at its circumferencial direction, the end of the axle sleeve that is connected with the input shaft of braking device is provided with one group of groove equally, when the axle sleeve that is located at the input shaft on power shovel winch output shaft and the braking device respectively is plugged on a time-out mutually, just formed the coupling that connects diaxon, when two axle sleeves are pegged graft in this coupling, usually the surface of contact in the groove both sides is provided with elastic block rubber as buffer unit, and be provided with packing with the sleeve diameter Spielpassung in the axle sleeve on the output shaft of power shovel winch, with the radially mounting point of restriction elastic block rubber.Be exactly that this simple packing brings a lot of troubles to real work, at first, because packing and sleeve diameter are Spielpassung, packing and sleeve diameter are kept away unavoidable slide relative in the operation process, make very quick-wearing of packing, and winch work the time often shuts down, or stops earlier afterwards turning to, and can bring very big vibrations during braking, frequent braking-vibrations also can make the very fast distortion of the packing after the wearing and tearing, and then come off, can cause equipment failure when serious, influence is produced.
Summary of the invention
The purpose of this utility model provides the coupling that is provided with fixing interior packing that a kind of power shovel winch is used, packing slip, wear phenomenon in avoiding, the replacing number of times of packing in reducing, prolongation power shovel winch device maintenance cycle.
The purpose of this utility model is to realize in the following manner:
The coupling that is provided with fixing interior packing that power shovel winch of the present utility model is used, comprise the coupling left axle sleeve that is located on the power shovel winch output shaft, the left axle sleeve coupling right axle sleeve of pegging graft therewith, be located at the elastic block rubber of coupling left axle sleeve and coupling right axle sleeve splicing position and be located at the interior interior packing of coupling left axle sleeve, it is characterized in that having an end face baffle plate to fix with the termination of described interior packing is connected, this end face baffle plate fixes with the coupling left axle sleeve by bolt device and is connected, and packing and coupling left axle sleeve connect into as a whole in making.
The utility model has the advantages that:
Interior packing is fixed on the left axle sleeve, and the generation of anti-sliding stop, wearing and tearing even vibrations can not make interior packing come off yet, reduces the number of times of packing parts in changing, and prolongs the service cycle of power shovel winch equipment, the assurance safety in production.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is the A-A sectional view of Fig. 1.
Accompanying drawing 3 is the left view of Fig. 2.
Embodiment
Below in conjunction with description of drawings embodiment of the present utility model.
As shown in Figure 1, the coupling that is provided with fixing interior packing that power shovel winch of the present utility model is used, comprise the coupling left axle sleeve 2 that is located on the power shovel winch output shaft 1, the left axle sleeve 2 coupling right axle sleeve 5 of pegging graft therewith, be located at the elastic block rubber 6 of coupling left axle sleeve 2 and coupling right axle sleeve 5 splicing positions and be located at interior packing 3 in the coupling left axle sleeve 2, it is characterized in that having an end face baffle plate 8 to fix with the termination of described interior packing 3 is connected, this end face baffle plate 8 fixes with coupling left axle sleeve 2 by bolt device 7 and is connected, and packing 3 connects into as a whole with coupling left axle sleeve 2 in making.This structure can limit the radial position of elastic block rubber 6, does not slide between packing 3 and the coupling left axle sleeve endoporus in guaranteeing again, thereby has guaranteed that the power shovel winch can not damage interior packing in braking process, improved the working life of interior packing.
As shown in Figure 2, elastic block rubber 6 is evenly distributed in the coupling right axle sleeve 5; As shown in Figure 3, coupling left axle sleeve 2 plugs with right axle sleeve 5.
As sequence number among Fig. 1,34 is the input shaft of braking device.
