Abstract
A gear angular velocity measuring device comprises a gear and a measurer. The measurer is arranged on one side of the gear. One end of the measurer is provided with a signal processor. The signal processor is connected with a coil through a lead a and a lead b. An inductive iron core penetrates through the center of the coil. One end of the inductive iron core is arranged on the outer portion of a shell of the measurer. The other end of the inductive iron core is connected with a magnet. The distance between the gear and the inductive iron core ranges from 2 millimeters to 4 millimeters. The magnet is a permanent magnet with strong magnetism. The gear angular velocity measuring device has the advantages that the structure is simple, installation and use are convenient, inductive measurement improves measuring accuracy and stability, the authenticity of instrument reading is guaranteed, and overspeed caused by instrument reading errors is avoided.
Description
Technical field
The present invention designs a kind of angular velocity measurement device, especially a kind of gear angular velocity measurement device.
Background technology
Ancient Chinese far away from B.C. 400 ~ 200 years brings into use gear with regard to the sixth of the twelve Earthly Branches, and the bronze gear be unearthed in China Shanxi is the most ancient gear found the sixth of the twelve Earthly Branches so far, and the vehicle pointing to the south as reflection Ancient Science and technolog achievement is exactly take gear mechanism as the mechanical hook-up of core.The 17th century Mo, people just begin one's study, and correctly can transmit the tooth profiles of motion.In 18th century, after the European industrial revolution, gear-driven application is increasingly extensive; Developing cycloidal gear before this, is then involute gear, until 20 beginnings of the century, involute gear account for advantage in the application.In daily life, our mechanical ware be unable to do without gear, little of wrist-watch, the large application to aeronautical and space technology.
There are a lot of vehicles in the world at present, wherein automobile is exactly one of most important vehicles, automobile instrument panel all can be provided with velometer and engine speed indicator, reading on table is all by the measurement to service part, the reading obtained after entering a series of data processing, traditional rotary speed pickup in use between long after easily there is the phenomenon damaged, thus accurately can not reflect the instantaneous velocity of vehicle, bring very large trouble to numerous drivers, the technology being therefore badly in need of a kind of improvement solves above-mentioned technological deficiency.
Summary of the invention
The invention provides a kind of gear angular velocity measurement device.
The present invention is directed to the technical scheme that above-mentioned technological deficiency proposes is:
A kind of gear angular velocity measurement device, comprise gear and measuring appliance, described measuring appliance is placed in gear side, described measuring appliance one end is provided with signal processor, described signal processor is by wire a and wire b connecting coil, described coil central authorities are installed with inductive iron core, and described inductive iron core one end is placed in measuring appliance housing exterior, and the described inductive iron core other end connects magnet.
Distance between described gear and inductive iron core is 2-4 millimeter.
Described magnet is strong magnetic permanent magnet.
The invention has the beneficial effects as follows: structure is simple, install and use more for convenience, inductive measuring improves the Stability and veracity of measurement, ensure that the authenticity of meter reading, avoids the hypervelocity caused because of meter reading mistake.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein: 1, gear, 2, measuring appliance, 3, measuring appliance shell, 4, signal processor, 5, wire a, 6, wire b, 7, coil, 8, magnet, 9, inductive iron core.
Embodiment
A kind of gear angular velocity measurement device, comprise gear 1 and measuring appliance 2, measuring appliance 2 is placed in gear 1 side, the inner one end of measuring appliance 2 is provided with signal processor 4, signal processor 4 is by wire a5 and wire b6 connecting coil 7, coil 7 central authorities are installed with inductive iron core 9, it is outside that inductive iron core 9 one end is placed in measuring appliance shell 3, inductive iron core 9 other end connects magnet 8, distance between gear 1 and inductive iron core 9 is 2-4 millimeter, magnet 8 is strong magnetic permanent magnet, structure is simple, install and use more for convenience, inductive measuring improves the Stability and veracity of measurement, ensure that the authenticity of meter reading, avoid the hypervelocity caused because of meter reading mistake.
