Abstract

The utility model relates to an axial locking structure for a vertical motor, comprising a motor main shaft, a flat key, a half coupling, a split ring key, a ring key sheath, a bolt and a spring gasket, wherein the position of the motor main shaft near an end face is provided with an annular key groove, inside the annular key groove there is provided the split ring key, the ring key sheath radially limits the split ring key, the ring key sheath is fastened on the motor main shaft by the bolt and the spring gasket, the half coupling is rigidly connected with the main shaft of a load, a plane where the end portion of the ring key sheath is located is lower than a plane where the end portion of a ring key is located, and the ring key sheath cannot bear the axial load of the half coupling. The axial locking structure for a vertical motor can axially lock the half coupling without any machining means and special tools in the process of assembling at construction field, is reliable, simple and convenient in operation, dispenses with screw thread connection on main bearing components, does not cause any wearing after dismounting for many times, and is good in consistency.

Description

The vertical machine axial locking structure
Technical field
The utility model relates to a kind of draw bail of axle of two coaxial lines that are rigidly connected, and is specifically related to the positive coupling between vertical machine and connection main frame.
Background technology
Vertical machine is exactly the vertically arranged motor of axial line of electric machine main shaft.Vertical machine is generally used for connecting the vertical-type axial-flow pump even load, the spindle axis line of vertical machine and load is positioned on same axis, the common flexible connection of connection between the main shaft of vertical machine and load and the two kinds of forms that are rigidly connected, the main shaft of vertical machine only bears moment of torsion, does not bear axial force when elasticity connects, and when being rigidly connected, will bear moment of torsion and xial feed simultaneously.Existing structure usually adopts nut to carry out axial locking and bears axial force, while assembling at the scene, need specific purpose tool or manufacturing process to carry out locking processing to nut, structure is comparatively complicated, and being dismounted for multiple times also can cause to nut and electric machine main shaft the damage of unrepairable.
The utility model content
The purpose of this utility model is to provide a kind of vertical machine axial locking structure, complex structure and the poor problem of being dismounted for multiple times consistency while solving the existing structure assembling.
For achieving the above object, the technical solution of the utility model is: the vertical machine axial locking structure, comprise electric machine main shaft, flat key, half a coupler, distinguish ring key, ring key sheath, bolt and spring washer, described electric machine main shaft offers an annular keyway near endface position, place the distinguish ring key in the annular keyway, and with the radially spacing distinguish ring key of ring key sheath, the ring key sheath is fastened on electric machine main shaft by bolt and spring washer.
While adopting technique scheme, because half a coupler is rigidly attached on the main shaft of load, the axial force on the load main shaft and moment of torsion are delivered on half a coupler, and half a coupler transmits respectively axial force and moment of torsion by distinguish ring key and flat key.By annular keyway is set on electric machine main shaft, place the distinguish ring key, transmit the xial feed from half a coupler by the distinguish ring key, ring key adopts the design of distinguish, the ring key of rigidity can be put into to corresponding keyway on axle, radially hold ring key tightly by the ring key sheath again, make the various piece of distinguish preserve a globality, be unlikely to come off.In addition, the plane, place of the end of ring key sheath is lower than the plane, place of ring key end, the ring key sheath will can not contact with the inner face of half a coupler like this, the ring key sheath will can not be subject to the xial feed of half a coupler, Each performs its own functions for distinguish ring key and ring key sheath, the division of labor is clear and definite, while assembling at the construction field (site), this structure can complete the axial locking of half a coupler without any need for machine work means and specific purpose tool, operate reliably easy, main load bearing component is not threaded, and after being dismounted for multiple times, can not cause any wearing and tearing, high conformity yet.
Further, for the ease of processing and the installation of ring key, described distinguish ring key is at least two lobes.
Further, because the ring key sheath can not bear xial feed, therefore, and described ring key sheath and being fixed on electric machine main shaft by bolt and spring washer, the plane, place of described ring key sheath end face is lower than the plane, end face place of distinguish ring key.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model vertical machine axial locking structure embodiment.
Embodiment
As shown in Figure 1, shown the motor side syndeton of vertical machine axial locking structure in figure, because the structure of the structure at the equipment dynamic input and motor side is identical, Gu do not do the explanation of repetition.
The vertical machine axial locking structure, comprise between electric machine main shaft 1, electric machine main shaft and half a coupler 2 by flat key 11 transmitting torques.Described electric machine main shaft 1 offers an annular keyway 12 near endface position, the interior distinguish ring key 3 of having placed of annular keyway 12, distinguish ring key 3 is divided into pintongs, and with ring key sheath 4, carries out radially spacingly, and ring key sheath 4 is fastened on electric machine main shaft 1 by bolt and spring washer 41.Because half a coupler 2 is rigidly attached on the electric machine main shaft 1 of load, the axial force on load motor main shaft 1 and moment of torsion are delivered on half a coupler 2, and half a coupler 2 transmits respectively axial force and moment of torsion by distinguish ring key 3 and flat key 11.By annular keyway 12 is set on electric machine main shaft 1, place distinguish ring key 3, the xial feed of transmitting from half a coupler 2 by distinguish ring key 3, ring key adopts the design of distinguish, the ring key of rigidity can be put into to corresponding keyway on axle, radially hold ring key tightly by ring key sheath 4 again, make the various piece of distinguish preserve a globality, be unlikely to come off.In addition, the plane, place of the end of ring key sheath 4 is lower than the plane, place of ring key end, ring key sheath 4 will can not contact with the inner face of half a coupler 2 like this, ring key sheath 4 will can not be subject to half 2 xial feed, Each performs its own functions for distinguish ring key 3 and ring key sheath 4, the division of labor is clear and definite, while assembling at the construction field (site), this structure can complete the axial locking of half a coupler 2 without any need for machine work means and specific purpose tool, operate reliably easy, main load bearing component is not threaded, and after being dismounted for multiple times, can not cause any wearing and tearing, high conformity yet.
Above-described is only preferred implementation of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection range of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
