Abstract
The utility model discloses a no key rotor, its technical scheme main points are no key rotor, including rotor core and axis body, rotor core comprises the rotor punching, the rotor punching inner circle is equipped with the lug, driving key is constituteed to the lug, the axis body surface is equipped with the keyway corresponding with rotor core's driving key, the keyway both ends are run through, the rotor core both ends are equipped with the spacing apron of axial, be equipped with radial lock nut on the apron, radial lock nut can dismantle with the axis body and be connected. Set up rotor core and driving key through such integration, can directly use rotor core, saved driving key's use, increased overall structure's stability simultaneously, on the other hand adds the welding with the two nut lockings of tradition and compares, no key rotor's dismantled connection can improve the utilization ratio of rotor, has avoided the dumped problem that lost efficacy because of the screw is firm, saves the cost more, and stability is higher.
Description
Technical field
The utility model relates to a kind of mechanical industry articles for use, and more particularly, it relates to a kind of without key rotor.
Background technology
Rotor is a kind of rotary body by bearings, is mostly the main rotation member in dynamic power machine and work mechanism.
At present, rotor disclosed on market often needs the cooperation of key, in use, first needing to mate corresponding key, but certainly exist space between key and keyway, there is axial motion by gap in axis body, cause axis body bumpy running, and easily produce wearing and tearing, therefore intensity is not high; Because traditional rotor part adopts double nut to lock and the mode of welding, strength of stability for radial direction is difficult to ensure, there is damaging maintenance difficult of later doing over again in further nut and trip bolt, be difficult to take out still unspoiled rotor punching, therefore cause the cost of damage higher, and waste large content of starting materials.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of dismountable without key rotor.
For achieving the above object, the utility model provides following technical scheme: a kind of without key rotor, comprise rotor core and axis body, described rotor core is made up of rotor punching, and described rotor punching inner ring is provided with projection, described projection composition driving key, described axis body surface is provided with the keyway corresponding with rotor core, and described keyway two ends are run through, and described rotor core is provided with cover plate, described cover plate is provided with radial locking nut, and described radial locking nut and axis body removably connect.
The utility model is set to further: described radial locking nut is provided with trip bolt, and the axially-extending line of described trip bolt forms the angle of 120 °.
The utility model is set to further: described radial locking nut is provided with groove, and described cover plate is provided with through hole, and described rotor core is provided with rectangular groove.
The utility model is set to further: described rotor core is provided with the first screwed hole, and described cover plate is provided with second screwed hole corresponding with the first screwed hole position.
Compared with prior art, the utility model has the advantage of: rotor punching inner ring is provided with projection, projection composition driving key, save the use of extra key, add the intensity of rotor, axis body and radial locking nut removably connect, during use, radial locking nut is fixed by trip bolt and axis body, where necessary by taking out each trip bolt, then dismantling radial locking nut replacing associated damage accessory and can promote rotor bulk life time saving cost, improving the utilance not damaging accessory; Rotor core and cover plate are fixed by trip bolt, the friction of rotor core and cover plate when decreasing running, avoid the some mechanical energy wasted because of sliding friction, three trip bolts on radial locking nut form triangles, ensure that certain stability according to triangle.

Fig. 2 is the three-dimensional view of the utility model without key rotor embodiment.
Reference numeral: 1, radial locking nut; 2, cover plate; 3, axis body; 4, through hole; 5, projection; 6, rotor punching; 7, rectangular groove; 8, the first screwed hole; 9, the second screwed hole.
Embodiment
Referring to figs. 1 through Fig. 2, the utility model is described further without key rotor embodiment.
A kind of without key rotor, comprise rotor core and axis body 3, rotor core is made up of rotor punching 6, rotor punching 6 inner ring is provided with projection 5, projection 5 forms driving key, save extra driving key, ensure that intensity simultaneously, axis body 3 surface is provided with the keyway corresponding with the driving key of rotor core, keyway two ends are run through, during use, position corresponding according to keyway for the rotor punching 6 of superposition is put into, now axis body 3 is not axially fixed, rotor core is placed cover plate 2, cover plate 2 use radial locking nut 1 screw with rotor core, prevent the sliding friction that cover plate 2 and rotor core are mutual, by radial locking nut 1 with cover plate 2 by axis body 3 axial restraint, prevent sliding axially of axis body 3, radial locking nut 1 removably connects with axis body 3 simultaneously, therefore can replace in time when radial locking nut 1 breaks down, ensure that rotor can continue to use, the useful life of Extending Rotor entirety.Radial locking nut 1 is provided with trip bolt, trip bolt destroys the screw thread of radial locking nut 1, ensure the firm effect of radial locking nut to rotor core, the axially-extending line of trip bolt forms the angle of 120 °, the method adopting three orientation to arrange trip bolt is fixed, utilize leg-of-mutton stability to improve the firm effect of radial locking nut 1, save used screw number simultaneously.
Cover plate 2 is provided with through hole 4, locking nut has groove, rotor punching 6 is provided with rectangular groove 7 and through hole 4, each component materials is saved by such scheme, under the prerequisite of proof strength, alleviate the weight of each parts simultaneously, because during running, axis body 3 speed is fast, alleviate component weight and effectively can reduce the component wear that co-acting force brings, further because the transformation of each components interior body also improves overall heat-sinking capability, reduce temperature during rotor operation.
The above is only preferred implementation of the present utility model, protection range of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
