Abstract
The utility model discloses a castellated coupling which comprises an upper shaft and a lower shaft installed concentrically through a connecting rod, wherein two ends of the connecting rod are respectively inserted in connection holes at the ends of the upper shaft and the lower shaft; a castellated coupling is sheathed on the connecting rod, the shaft end where the upper shaft is connected with the connecting rod and the shaft end where the lower shaft is connected with the connecting rod; the castellated coupling has a castellated boss-shaped structure; the coupling is sheathed with the connecting rod tightly; a boss buckled upper shaft is arranged at the shaft ends where the coupling is connected with the upper shaft and the connecting rod; and a boss buckled lower shaft is arranged at the shaft ends where the coupling is connected with lower shaft and the connecting rod. In the utility model, the connecting rod and the shaft ends of the upper shaft and the lower shaft are buckled through the boss structure of the castellated coupling, so that the connecting rod can be tightly connected with the upper shaft and the lower shaft so as to play a very good coupling role.
Description
Technical field
The utility model relates to a kind of mechanical structure, specifically, relates to a kind of jaw type coupler.
Background technique
Coupling is diaxon axially to be linked up and the parts of transmitting torque and motion and have the ability of certain compensation parallel offset, and for the vibration that reduces machine driven system, reduce and impact spike load, coupling also should have certain bumper and absorbing shock performance.Coupling also has the overload protective action sometimes concurrently.
Coupling generally can be divided into two big classes: rigidity and flexibility.
Rigid coupling is very high for the requirement of two between centers concentricitys, does not have compensation by the ability of connection two axis relativity shifts, does not also have the bumper and absorbing shock performance; But simple in structure, low price.Only steady in load, stabilization of speed can guarantee to be joined under the minimum situation of two axis relativity shifts, just can select rigid coupling for use.Therefore flexible coupling is widely used.Flexible coupling mainly contains:
Flexible coupling: have the ability that certain compensation is joined two axis relativity shifts.
The flexible coupling of inelastic component: bearing capacity is big, but does not also have the bumper and absorbing shock performance, at a high speed or rotary speed unstabilization is fixed or often during forward and backward, impact noise is arranged.Be applicable to low speed, heavy duty, rotating speed occasion stably.
The flexible coupling of nonmetal elastic element: good bumper and absorbing shock performance is arranged when rotating speed is not steady; But since nonmetal (rubber, nylon etc.) elastic element intensity is low, the life-span is short, bearing capacity is little, non-refractory and low temperature, so be applicable to the occasion of high speed, underloading and normal temperature.
The flexible coupling of metallic elastic component: except having preferably the bumper and absorbing shock performance, bearing capacity is bigger, is applicable to that speed and load change reach high temperature or low temperature situation more greatly.
Safety coupling: characteristics structurally are, have an insurance link (connecting etc. as pin is movable), and it can only bear qualification load.When actual load surpassed the load that in advance limits, the insurance link just changed, and blocks the transmission of motion and power, thereby the unlikely damage of remaining part of protection machine promptly plays the safety protection effect.
Starting safety coupling: except having overload protective function, also have the effect that the loaded starting of machine motor is changed into approximate starting under no load.
Big owing to the unit axial dimension in the high-lift pump, pump shaft is longer, and difficulty of processing is bigger, original identical diameter of axle coupling, and after the pump housing enlarged diameter, the both difficult processing of this equipment, waste material uses undesirable again again.
The model utility content
The utility model technical issues that need to address just are to overcome the defective of prior art, a kind of jaw type coupler is provided, the axle head of its boss structure fastening connecting rod by jaw type coupler and last axle, lower shaft, so just can make connecting rod keep closely being connected, play extraordinary shaft coupling effect with last axle and lower shaft.
For addressing the above problem, the utility model adopts following technological scheme:
A kind of jaw type coupler of the utility model, comprise upward axle and the lower shaft installed with one heart by connecting rod, the two ends of connecting rod are plugged on respectively in the axle and the axle head attachment hole of lower shaft, described connecting rod, go up a axle head that axle is connected with connecting rod, reach the axle head that lower shaft is connected with connecting rod and be set with a jaw type coupler; Described jaw type coupler is castellated boss shape structure, the tight socket of shaft coupling and connecting rod, shaft coupling is provided with axle in the boss fastening with the axial end that last axle is connected with connecting rod, and shaft coupling is provided with a boss fastening lower shaft with the axial end that lower shaft is connected with connecting rod.
The diameter of axle of going up axle and lower shaft described in the utility model can equate.
Perhaps, the diameter of axle of going up axle and lower shaft described in the utility model can be unequal.
The utility model is applicable to that the axle between the identical diameter of axle or the different diameter of axle connects, the axle head of boss structure fastening connecting rod by jaw type coupler and last axle, lower shaft, so just can make connecting rod keep closely being connected with last axle and lower shaft, make it into as a wholely, the axle that is specially adapted to the different diameters of axle in the high-lift pump connects.Have compact structure, installation, use, easy to maintenance simple, dismounting is efficient and convenient, vibrates little, advantages such as noise is low, long service life, unit efficiency height, noise free.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, a kind of jaw type coupler of the utility model, comprise upward axle 2 and the lower shaft 3 installed with one heart by connecting rod 1, the two ends of connecting rod are plugged on respectively in the axle and the axle head attachment hole of lower shaft, described connecting rod, go up a axle head that axle is connected with connecting rod, reach the axle head that lower shaft is connected with connecting rod and be set with a jaw type coupler 4.
Described jaw type coupler is castellated boss shape structure, the tight socket of shaft coupling and connecting rod, shaft coupling is provided with axle in the boss fastening with the axial end that last axle is connected with connecting rod, and shaft coupling is provided with a boss fastening lower shaft with the axial end that lower shaft is connected with connecting rod.
The described diameter of axle of going up axle and lower shaft can equate.
Perhaps, the described diameter of axle of going up axle and lower shaft can be unequal.
The utility model is applicable to that the axle between the identical diameter of axle or the different diameter of axle connects, the axle head of boss structure fastening connecting rod by jaw type coupler and last axle, lower shaft, so just can make connecting rod keep closely being connected with last axle and lower shaft, make it into as a wholely, the axle that is specially adapted to the different diameters of axle in the high-lift pump connects.Have compact structure, installation, use, easy to maintenance simple, dismounting is efficient and convenient, vibrates little, advantages such as noise is low, long service life, unit efficiency height, noise free.
It should be noted that at last: obviously, the foregoing description only is for the utility model example clearly is described, and is not the qualification to mode of execution.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all mode of executions.And conspicuous variation of being extended out thus or change still are among the protection domain of the present utility model.
