Description
Technical field
This utility model is related to a kind of flywheel limiter of speed, belongs to technical field of transportation.
Background technology
At present, because the rotation speed change of bicycle middle shaft is larger, so that the input speed of electromotor is changed, lead to electromotor
Even if electricity through transformator nor to constant electric current and voltage, bring many inconvenience to user power utilization, such as electric current becomes
Change and damage charge mobile phone and other power supplys, be unfavorable for powering.Existing wheel friction limiter of speed, because middle rotating speed is too fast, right
The loss of car is larger and speed limit is inaccurate.
Content of the invention
The technical problems to be solved in the utility model is to provide a kind of flywheel limiter of speed, and energy effectively solving is because of bicycle gear ring
The faster rotational speed that rotating speed is too fast and leads to axis, serves the effect of rotating speed in restriction, is provided for electromotor by this device
Stable rotating speed, so that transformator output constant current and voltage, reduces charge-up damage, has reached good restriction axis simultaneously
The effect of rotating speed, solves the problems, such as that the abrasion of friction speed limit is beaten and speed limit is inaccurate.
The technical solution adopted in the utility model is：A kind of flywheel limiter of speed, including axis 7, foreign steamer 6, axis 7 outer ring is pacified
Equipped with ratchet 3, ratchet 3 starting point is provided with spring 10, and rotatable roundlet wheel 2 is installed in the end of ratchet 3, and ratchet 3 end is simultaneously solid
One end of alignment 1, the other end of line 1 draws centrifugal weights 9 by axis center, and axis 7 is provided with control line 1 and centrifugal weights
The baffle plate 8 in 9 directions, foreign steamer 6 includes ratchet 5 and gear ring 4, ratchet 3 with axis 7 motion closer or far from ratchet 5.
Preferably, the end of described ratchet 3 is provided with hole, and one end of line 1 is fixed on ratchet 3 end through described hole.
Select excellently, described baffle plate 8 includes base plate and is located at base plate both sides side plate, line 1 and centrifugal weights 9 protruding upward
In the groove that base plate and side plate are formed.
Select excellently, described baffle plate 8 is welded on axis 8.
Preferably, described baffle plate 8 and axis 7 are integrally formed.
Preferably, described roundlet wheel 2 is fixed on the end of ratchet 3 by rotating shaft.
Operation principle of the present utility model is：Drive axis 7 to rotate by ratchet 5 and ratchet 3 when gear ring 4 rotates, line 1 and
Centrifugal weights 9 produce centripetal force, and centripetal force has pulling force to ratchet 3 end, and when turn up restriction level, centrifugal weights 9 provide
Centripetal force sufficiently large, ratchet 3 is pulled to axis center of circle direction, leaves ratchet 5, do not have ratchet 5 to act on, rotating speed no longer rises,
Rotating speed is less than when limiting rotating speed, leads to centripetal pulling force to reduce, and under spring 10 effect, ratchet 3 and ratchet 5 coincide, i.e. roundlet wheel 2
Contact with ratchet 3 at one piece, speed rises, so repeatedly so that axis 7 rotating speed maintains in the smaller range of setting, for sending out
Motor and other devices provide constant rotating speed, export constant rotating speed through flywheel limiter of speed simultaneously.
Beneficial effect
1st, constant rotational speed can be provided for electromotor so that transformator output constant current and voltage, reduce charge-up damage；
2nd, axis 7 stabilization of speed, solves the problems, such as that existing friction limiter of speed is big to car abrasion and speed limit is inaccurate；
3rd, by centrifugal weights 9 mass size come speed limit, output speed size can be controlled；
4th, structure is simple, energy-conserving and environment-protective, low cost.
Brief description
Fig. 1 is structural representation of the present utility model.
In figure is respectively numbered：Line -1, roundlet wheel -2, ratchet -3, gear ring -4, ratchet -5, foreign steamer -6, axis -7, baffle plate -8,
Centrifugal weights 9, ratchet spring 10.
Specific embodiment
With reference to the accompanying drawings and examples, the utility model is described in further detail, but content of the present utility model is not
It is limited to described scope
Embodiment 1：As shown in figure 1, a kind of flywheel limiter of speed, including axis 7, foreign steamer 6, axis 7 outer ring is provided with ratchet
3, ratchet 3 starting point is provided with spring 10, and rotatable roundlet wheel 2 is installed in the end of ratchet 3, ratchet 3 end simultaneously fixing line 1 one
End, the other end of line 1 draws centrifugal weights 9 by axis center, and axis 7 is provided with control line 1 and the gear in centrifugal weights 9 direction
Plate 8, foreign steamer 6 includes ratchet 5 and gear ring 4, ratchet 3 with axis 7 motion closer or far from ratchet 5.
According to centrifugal weights 9 mass size come speed limit, ratchet 3 is connected with centrifugal weights 9 by line 1, and axis 7 speed increases
When, centrifugal weights 9 produce centripetal pulling force, i.e. centrifugal tension, pull ratchet 3 clutch with centrifugal tension, rely under ratchet 3 starting point
