Abstract
The utility model relates to a single cylinder diesel field, mainly used low inertia ratio flyweight formula speed regulator. The structure is characterized in that a ring 4 of a flyweight bracket is thickened, a through groove 5 is formed in the ring at the position where fan-shaped flyweights 1 are symmetrically installed, and a flyweight shaft 2 is positioned by a pin 3. The speed regulation device has the obvious advantages that a lubricating oil hole of flyweight oil can be omitted, the processing is obvious and simple, the speed regulation performance is improved, the stable speed regulation rate can reach delta being less than or equal to 4%, the rotating speed fluctuation rate psi is less than or equal to 0.25%, the lowest stable working rotating speed is 100-150 rpm lower than that of a sliding disc type speed regulator, the low-speed noise is obviously reduced, and the service life is prolonged by more than 3 times than that of the sliding disc type speed regulator.
Description
The utility model relates to the single cylinder diesel field, is mainly used in low ratio of inertias flyball governor.
The state-of-the-art technology of the speed control system of China's single cylinder diesel employing at present is that the patent No. is: 90211568.5 " flyball governor ", it mainly is made up of speed regulation gear, flyball, flying hammer bracket, speed governing mandrel, timing gear wheel shaft and governor lever etc., therefore this structure can save oilhole because the lubricated of flyweight shaft do not have problems.But there is the circle ring rack insufficient rigidity, yielding, can not guarantee the proper functioning of speed regulator, the shortcoming such as fixing unreliable of flyweight shaft.
The purpose of this utility model is reliably to provide a kind of novel fan-shaped flyball structure in order to save oilhole, to strengthen flying hammer bracket annulus rigidity and flyweight shaft is fixed.
The purpose of this utility model is achieved in that as shown in Figure 3, the patent No. of having authorized is: the oilhole 7 in 90211568.5 the flyball structure can save, cause the lubricated of flyweight shaft 2 in actual use can be provided by driving gear, does not have lubrication problem.As Fig. 1, shown in Figure 2, in order to strengthen flying hammer bracket rigidity, promptly flying hammer bracket annulus 4 is thickeied, and on the annulus of two flyballs symmetry mounting point, opened a groove 5, flyweight shaft is fixed by pin 3, prolong speed regulator working life thereby reach, improve the purpose of low-speed stability.
Concrete structure of the present utility model is provided by the following drawings and embodiment.
Fig. 1 is the utility model front view
Fig. 2 is the utility model plan view
Fig. 3 is the oilhole sectional view of the patent No. 90211568.5 patents.
In the accompanying drawings, each label name is called: 1. fan-shaped flyball, 2. flyweight shaft, 3. pin, 4. flying hammer bracket annulus, 5. groove, 6. screw hole, 7. oilhole.
Now describe the utility model concrete structure in conjunction with the accompanying drawings in detail:
As shown in Figure 1 and Figure 2, fan-shaped flyball 1 is the center of circle with the axle center of flyweight shaft 2; Two fan-shaped flyball 1 symmetries are installed on the flying hammer bracket annulus 4, and two bolts of flying hammer bracket annulus 4 usefulness are fastened on the speed regulation gear by screw 6.It is characterized in that: 4 thickenings of flying hammer bracket annulus are also opened a groove 5 on the annulus of its symmetry installation two fan-shaped flyballs 1 position, to guarantee the axial installation dimension of flyweight shaft to the speed governing mandrel.Flyweight shaft 2 is by pin 3 location, can prevent the play of flyweight shaft like this and causes the disengaging of flyball, improved the reliability of governor assembly.
Advantage of the present utility model: the fan-shaped flyball structure of low ratio of inertias flyball governor is compared with sliding plate formula speed regulator, processes bright Aobvious simple shape has been improved speed adjusting performance, and steady state speed governing rate δ≤4% (the sliding plate formula is δ≤8%) speed fluctuation rate ψ≤0.25% is (sliding Disc type is ψ≤1%). Lowest continuous speed with load is than low 100～150 rev/mins of sliding plate formula speed regulator; The low speed noise obviously reduces; Make Improve more than 3 times than sliding plate formula with the life-span.
