Description
Technical field
The utility model belongs to rotor technical field of auxiliary equipment, is specifically related to a kind of rotor overload protection device.
Background technology
According to iso standard, be called rotor by the rotary body of bearings.Rotor mostly is the main rotation member in dynamic power machine and work mechanism.Typical rotor has Turbomachine Rotor, rotor, the rotor of various pump and the rotor etc. of turbocompressor.Being there is very large distortion and cause resonance in rotor, causes rotating speed during resonance to be called the critical whirling speed of rotor when rotating under some specific rotating speed.In engineering, working speed is called stiff rotor lower than the rotor of first critical speed, and the rotor being greater than first critical speed is called flex rotor.Because high speed rotary motion made by rotor, so need balance.Static balance is mainly used in the inertia force balancing disk type rotor.The dynamic balancing of stiff rotor can come balance inertial force and inertia couple by universal balancing machine, eliminates the vibration of rotor on elastic bearing.The dynamic balancing more complicated of flex rotor, distinguishes from principle, has method of model balancing and influence coefficient method two class.Rotor because of the difficulty that commutates, high, the various fault of rotating speed multiple.Common fault has commutator damage, bearing damage, fan blade damage, wear of brush, rotor windings to burn.
Utility model content
The purpose of this utility model is to provide a kind of rotor overload protection device, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of rotor overload protection device, comprise blank flange, Compress Spring, rotor, spring base and ring flange, the upper end of described rotor offers the stopper slot of annular, described spring base is arranged on stopper slot, the upper end of described Compress Spring is fixed on the lower surface of spring base by spring clip, described blank flange is arranged on the below of spring base, the lower end of described Compress Spring is fixed on the upper surface of blank flange by spring clip, the lower surface of described blank flange is provided with semicircle steel ball, described ring flange is arranged on the below of blank flange, the upper surface of described ring flange offers the semicircle orifice matched with semicircle steel ball, the upper surface of described ring flange is disk cover, the middle part of described disk cover is provided with frosted dish, the lower surface of described ring flange is for sitting crosslegged, described lower end of sitting crosslegged is provided with sealing surface, described spring base, the middle part of blank flange and ring flange is provided with through hole.
Preferably, sit crosslegged described in, with the interface of sealing surface, supporting bracket is installed.
Preferably, described semicircle orifice is connected with semicircle steel ball caulking groove, and is six.
Preferably, the through hole radius of described spring base is less than the radius of rotor.
Compared with prior art; the beneficial effects of the utility model are: this rotor overload protection device is convenient and practical; rotor speed can be maintained within the specific limits; when rotating speed is too fast; ring flange can be separated with blank flange; thus motor can lose with connector and is in transmission connection; thus protection motor can not reduce life-span or damage because of overload; if mixer rotor; when falling into hard object in rotating cylinder, hammer leaf is beaten in hard object, under force; ring flange also can be separated with blank flange, thus the safety of protection rotor.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;

In figure: 1, sealing surface, 2, sit crosslegged, 3, disk cover, 4, semicircle orifice, 5, blank flange, 6, Compress Spring, 7, rotor, 8, stopper slot, 9, spring base, 10, spring clip, 11, semicircle steel ball, 12, frosted dish, 13, ring flange, 14, supporting bracket and 15, through hole.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1-3, the utility model provides a kind of technical scheme: a kind of rotor overload protection device, comprise blank flange 5, Compress Spring 6, rotor 7, spring abutment 9 and ring flange 13, the upper end of rotor 7 offers the stopper slot 8 of annular, spring base 9 is arranged on stopper slot 8, the upper end of Compress Spring 6 is fixed on the lower surface of spring base 9 by spring clip 10, blank flange 5 is arranged on the below of spring base 9, the lower end of Compress Spring 6 is fixed on the upper surface of blank flange 5 by spring clip 10, the lower surface of blank flange 5 is provided with semicircle steel ball 11, ring flange 13 is arranged on the below of blank flange 5, the upper surface of ring flange 13 offers the semicircle orifice 4 matched with semicircle steel ball 11, semicircle orifice 4 is connected with semicircle steel ball 11 caulking groove, and be six, the upper surface of ring flange 13 is disk cover 3, the middle part of disk cover 3 is provided with frosted dish 12, the lower surface of ring flange 13 is for sitting crosslegged 2, sit crosslegged 2 lower end sealing surface 1 is installed, sit crosslegged and 2 with the interface of sealing surface 1, supporting bracket 14 is installed, spring base 9, the middle part of blank flange 5 and ring flange 13 is provided with through hole 15, through hole 15 radius of spring base 9 is less than the radius of rotor 7.
Operation principle: during use; blank flange 5 can dock with ring flange 13 under the effect of Compress Spring 6; thus the semicircle steel ball 11 of blank flange 5 lower surface meeting caulking groove is in the semicircle orifice 4 of ring flange 13 upper surface; in rotor 7 motion process; in the effect of power; semicircle steel ball 11 can produce the trend departing from semicircle orifice 4; when connector breaks down; produce larger resistance; or when rotor 7 rotating speed is excessive; semicircle steel ball 11 can depart from semicircle orifice 4, thus blank flange 5 is separated with ring flange 13, thus protects the safety of connector and motor.
Although illustrate and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that and can carry out multiple change, amendment, replacement and modification to these embodiments when not departing from principle of the present utility model and spirit, scope of the present utility model is by claims and equivalents thereof.
