Description
Technical field
The present invention relates to technical field of engines, particularly a kind of generator amature that limits rotates too fast mechanical rotation
Speed-limiting device.
Technical background
Generator carrys out the rotation of drive rotor by external force, and the energy of other forms is thus converted into electric energy.It is any
Generator has the rated speed of oneself, once the actual speed of rotor exceedes rated speed, just necessarily motor is produced larger
Harm, the lighter's motor overheating burns coil, and severe one causes bearing deformation, rotor to come off.Generator is caused to rotate the original overrun
It is many because having, such as thrust suffered by generator amature increases suddenly, speed limit bearing failure situations such as be likely to cause rotor speed
The unexpected increase of degree.
Although most of Generator Set has electromagnetic speed regulating device, these electromagnetic systems excessively rely on biography
The electric elements such as sensor and magnetic valve.Once meet with the emergency cases such as electromagnetic interference, power supply short circuit, thunderbolt, it is possible to occur
It is unexpected.In June, 2010, the unit of Shi Long power stations 1 just once occurred because the rotor that speed regulator failure is caused is overrun accident.
In addition, these electromagnetism speed limit devices also seem prohibitively expensive for the small-sized waterpower of some family expenses, wind-driven generator.Institute
To invent a kind of independent of electric power and cheap, dependable performance generator speed-limiting device, and use it to coordinate, mend
Existing electromagnetism speed limit system is filled to be very important.
The content of the invention
It is an object of the invention to provide a kind of completely without electric power, simple in construction, lower-cost mechanical turn
Dynamic speed-limiting device, so as to solve generator electromagnetism speed limit device when breaking down, can be effectively protected generating set.
The present invention is for the technical scheme that is used of its technical problem of solution：A kind of mechanical rotation limiter of speed, including gold
Belong to outer box, drive shaft sleeve, support, brake pad, pin, spring and bearing；
The support, brake pad pin and spring are each provided with three groups；The bottoms of three supports at equal intervals uniformly with
Drive shaft sleeve welds together, and drive shaft sleeve inner ring is provided with a fluting, and fluting matches with the projection on motor transmission shaft
Close, drive shaft sleeve can be made to be rotated with motor transmission shaft, metal outer box are connected by bearing with drive shaft sleeve, it is therefore an objective to protected
When card rotates drive shaft sleeve, metal outer box are remained stationary as；
Described brake pad one end is connected by pin with cradle top, and brake pad can be rotated by axle of pin；Brake pad
Middle part is connected with spring one end, and the other end of spring is fixed on support root.
As a kind of perferred technical scheme, the support is set from outer end to gradually being broadened at drive shaft sleeve the inner
Put.
As a kind of perferred technical scheme, the shape of three pack supports, three groups of pins, three groups of brake pads and three groups of springs is complete
Exactly the same, device is integrally centrosymmetric distribution.
As a kind of perferred technical scheme, thick middle, thin edge in the brake pad profile.
Compared with prior art, the beneficial effects of the present invention are：（1）The present invention is simple in construction, cost is relatively low, for
For the small-sized waterpower of some family expenses, wind-driven generator, price is subjected to；（2）Coordinate existing electromagnetic generator speed-limiting device,
The safety of generating set can more fully be protected；（3）The present invention provides economic, effective speed limit for small generator and solved
Scheme, dependable performance is the developing direction in alternate-engine field.

Fig. 2 is facing for the present invention.
1. metal outer ring in figure, 2. drive shaft sleeves, 3. supports, 4. brake pads, 5. pins, 6. springs, 7. bearings.
Embodiment
In order to further illustrate the present invention, below in conjunction with the accompanying drawings and the present invention is described in detail embodiment, but not
They can be interpreted as limiting the scope of the present invention.
A kind of mechanical rotation limiter of speed, including metal outer box 1, drive shaft sleeve 2, support 3, brake pad 4, the and of pin 5
Spring 6；The support 3, the pin 5 of brake pad 4 and spring 6 are each provided with three groups；Three pack supports 3, three groups of pins 5, three groups
Brake pad 4 is identical with the shape of three groups of springs 6, and device is integrally centrosymmetric distribution；Drive shaft sleeve inner ring is provided with one
Individual fluting, fluting is engaged with the projection on motor transmission shaft, drive shaft sleeve can be made to be rotated with motor transmission shaft.Outside metal
Box is connected by bearing 7 with drive shaft sleeve, it is therefore an objective to which when guarantee rotates drive shaft sleeve, metal outer box are remained stationary as.Hair
A drive shaft sleeve 2 is connected on the rotor shaft of motor, drive shaft sleeve 2 is rotated with the rotor shaft of generator,
The bottom of three supports uniformly welds together with drive shaft sleeve 2 at equal intervals, and support 3 is from outer end to close to driving sleeve
Gradually broaden setting at the inner of cylinder 2, strengthens the bonding strength between support 3 and drive shaft sleeve 2 with this, and the one end of brake pad 4 leads to
Cross pin 5 with the top of support 3 to be connected, brake pad 4 can be that axle is rotated with pin 5；The middle part of brake pad 4 and the one end of spring 6
It is connected, thick middle, thin edge in the profile of brake pad 4 strengthen the action effect of brake pad 4 with this, and the other end of spring 6 is fixed on
The root of support 3.
The specifically used course of work of the present invention：In stationary rotor or relatively low rotating speed, brake pad 4 is limited not by spring 6
With the contact aside of metal outer box 1；Generator amature rotating speed rise when, centrifugal force suffered by brake pad 4 is increasing, brake pad 4 around
The trend enhancing that pin 5 is turned out, the elongation of spring 6 is continuously increased；When rotor speed exceedes critical value, outside brake pad 4
Surface rubs with metal outer box 1, and the elongation of spring 6 no longer changes；Hereafter, rotor speed is bigger, outside brake pad 4 and metal
Pressure between the side of box 1 is bigger, and frictional force therebetween is also bigger, and therefore generator amature slows down；Work as generator failure
After exclusion, rotor speed return normal value, suffered by brake pad 4 centrifugal force decline, until centrifugal force be less than the pulling force of spring 6, then
Brake pad 4 departs from the side of metal outer box 1, comes back to normal position, and system recovers normal.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
