Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1 to Figure 2, the centrifugal rotational speed determiner of one described in the utility model, comprise two proving installations 1, rotating shaft 2, fixing display disc 3 and rotating disk 4, center place and rotating shaft 2 one end of described rotating disk 4 lower surface are fixedly connected, described proving installation 1 includes Double-layered transparent conduit 1-1 and end cap 1-5, and described Double-layered transparent conduit 1-1 one end is blind end; The sidewall of described rotating disk 4 is along the circumferential direction evenly provided with two trepannings matched with Double-layered transparent conduit 1-1 phase, the inner chamber of described Double-layered transparent conduit 1-1 is nested with check spring 1-2, colored gravitation ball 1-3 and outer spring 1-4 outward successively by inner, the intracavity bottom of described check spring 1-2 one end and trepanning is fixedly connected, and the described Double-layered transparent conduit 1-1 other end and end cap 1-5 are fixedly connected; Described outer spring 1-4 one end and end cap 1-5 are fixedly connected; Colored gravitation ball 1-3 is between the outer spring 1-4 other end and the check spring 1-2 other end.Described fixing display disc 3 lower surface is provided with the scale mark 3-1 matched with Double-layered transparent conduit 1-1 phase.Check spring 1-2 is used to cause colored gravitation ball 1-3 resilience to damage Double-layered transparent conduit 1-1 when preventing rotating shaft 2 stopping or stall suddenly.
Further, described end cap 1-5 is threaded mutually with the Double-layered transparent conduit 1-1 other end; The preload pressure to outer spring 1-4 is regulated by rotating end cap 1-5.
Further, described fixing display disc 3 adopts transparent material to be made.
Principle of work of the present utility model is: rotating disk 4 follows rotating shaft 2 to rotate together, and make the colored gravitation ball 1-3 in rotating disk 4 produce centrifugal force, colored gravitation ball 1-3 moves in Double-layered transparent conduit 1-1 inner chamber, compression outer spring 1-4.There is the centrifugal force of the colored gravitation ball 1-3 of Spring balanced that deformation produces in outer spring 1-4, colored gravitation ball 1-3 is stablized to fixed position in Double-layered transparent conduit 1-1.According to the position of Double-layered transparent conduit 1-1, read rotating speed by fixing display disc 3 by scale mark 3-1.Adopt quartzy smooth glass in Double-layered transparent conduit 1-1, to reduce resistance, reduce measuring error, ensure to measure accurately.
When using the utility model, this device can realize high-precision measuring, does not need external power supply all can complete normal gage work simultaneously, is very easy to user and measures at different conditions.In addition, this structure is simple, reasonable in design, low cost of manufacture.
The above is only better embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model patent claim change or modify, and are included in the utility model patent claim.
