Abstract
The utility model provides an encoder speed-increasing device which comprises an encoder, an encoder base fixedly connected with the encoder and a rotary shaft installed in the encoder base and used for providing power. The encoder speed-increasing device further comprises a small gear arranged on a center shaft of the encoder in a sleeved mode and a large gear which achieves linkage through a gear set fixed to a shell of the encoder, wherein the large gear is fixedly connected with the rotary shaft. The encoder speed-increasing device has the advantages of being capable of effectively increasing the rotation speed of the encoder, increasing the counting capacity of the encoder and collecting enough signals, thereby achieving high counting accuracy.
Description
Technical field
The utility model relates to scrambler correlative technology field, relates in particular to a kind of scrambler speeder.Background technology
Valve is in order to the device of pilot piping fluid flow or direction, and in existing valve, an electric valve executing mechanism is equipped with in big city, in these electric operators, generally uses scrambler to gather the lap signal that turns of rotating shaft, judges valve opening degree.In existing topworks, scrambler is directly connected with rotating shaft, if this mode is slower at rotating shaft rotating speed, in the shorter situation of stroke, the collection signal quantity of scrambler is inadequate, and then can cause the counting out of true that becomes.
Utility model content
Problem to be solved in the utility model is to provide a kind of scrambler speeder, for improving scrambler rotating speed, and then improves count number, makes counting become accurate.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of scrambler speeder, comprise scrambler and the encoder bases being fixedly connected with it, be contained in the rotating shaft that power is provided in encoder bases, also comprise the pinion wheel being sleeved on scrambler central shaft, and by being fixed on the gear wheel of the gear set interlock in encoder housing, gear wheel is fixedly connected with rotating shaft.
Further, described gear set comprises the first gear and the second gear being solid-located, and the first gear and pinion wheel are meshed, and the second gear and gear wheel are meshed.
Further, described gear set is fixedly connected on the housing of scrambler by bearing pin.
Further, place, the axle head axle center of described rotating shaft has hole, with the protrusion position interference fit on gear wheel.
Further, described rotating shaft is fixedly connected with by bearing pin with gear wheel.
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, increase gear-linked, can effectively improve the rotating speed of scrambler, increase the count number of scrambler, can gather enough signals, thereby reach higher counting precision.

In figure: 1-scrambler; 2-pinion wheel; 3-gear set; 4-gear wheel; 5-rotating shaft; 6-encoder bases; 7-bearing pin; 31-the first gear; 32-the second gear;
Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is illustrated:
In order to improve the counting effect of scrambler, as shown in Figure 1, the utility model provides a kind of scrambler speeder, the encoder bases 6 that comprises scrambler 1 and be fixedly connected with it, be contained in the rotating shaft of power 5 is provided in encoder bases 6, on the central shaft of this scrambler 1, be also set with pinion wheel 2, and by being fixed on the gear wheel 4 of gear set 3 interlocks on scrambler 1 housing, gear wheel 4 is fixedly connected with by bearing pin with rotating shaft 5.
Gear set 3 is fixedly connected on the housing of scrambler 1 by bearing pin, it comprises the first gear 31 and the second gear 32 being solid-located, the first gear 31 and pinion wheel 2 are meshed, and the second gear 32 and gear wheel 4 are meshed, and finally realize the interlock of pinion wheel 2 and gear wheel 4.
At the axle head axle center place of rotating shaft 5, have hole, the protrusion position interference fit being provided with gear wheel 4.
When rotating shaft 5 is rotated, drive gear wheel 4 to rotate, the second gear 32 being meanwhile meshed with gear wheel 4 is also driven to rotate, and then drive the first gear 31 be fixedly connected with the second gear 32, the first gear 31 drives with the pinion wheel 2 of its engagement again and rotates, the central shaft of the scrambler 1 at this moment being driven by pinion wheel 2 also starts rotation, the code-disc of scrambler 1 produces encoded radio, start counting, through gear wheel 4, the transformation of speed of gear set 3 and pinion wheel 2, the central shaft rotating ratio of rotating shaft 5 and scrambler 1 is 1:4, thereby slower at rotating shaft rotating speed, in the shorter situation of stroke, scrambler speeder improves 4 times by the rotating speed of scrambler 1, improve the number of turn-taking of scrambler 1, make scrambler 1 can gather enough signals, thereby reach higher counting precision.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
