Alarm Introduction
The alarm clock is a clock with a time to make trouble.It can not only indicate time, but also send audio signals or other signals at the time of people.The movement of the alarm clock is mainly mechanical and quartz electronics.Other types such as transistors swimming, sound fork -type, etc. are rarely used. Generally, the platform -type alarm clocks are placed on the table, which are mainly called travel alarm clocks used in travel.The daily error of the daily mechanical alarm clock is generally within 120 seconds/day, and the daily error of the quartz electronic alarm clock is generally within 0.2 seconds/day.
There are many types of alarm clocks, mechanical and quartz. Since the principle of being used by people, it has become an item that people cannot lack in peoples lives.
Alarm work principle
Use rolling spring (strip, a elastic element) to store energy expressed in the form of rectangular, and use a multi -stage gear with a fixed transmission ratio to display different time units.
Use a disk spring with accurate fixing vibration cycle (trace, a elastic element, manufactured by constant bombs alloy) and non-linear swing-brake-brake, professional is called a escapement mechanism.(Broken, an elastic element) Reserve the energy expressed in the form of force.The rotating angle speed of different pointers is different and they are constant.
Alarm clock component
1.
It is composed of a hammer, swing rod, hanging device and cycle adjustment device.Used in a fixed clock.After the hammer is dereated from the lead vertical line (balanced position) at any angle under the action of external forces, under the action of gravity, the hammer will be moved around the campaign.The vibration process is a process of switching energy and bit energy.
2. Twisted
It is mainly composed of panels and hanging wires.The lower end of the hanging wire is fixed, and the upper end is fixed on an unmoved fulcrum.The section of the hanging wire can be rectangular or round.Twisting and retreating agency or fork tile escaped agency constitutes the escapement speed system.The twisting has a long vibration cycle (a few seconds to tens of seconds), which is mostly used for a fixed clock with a longer energy than savings.
3. Swiming trace hood vibration system
The inside and inside of the shots are fixed on the shaft and splint, respectively.When the strain is deviated from its balanced position and starts to swing, the scarf is twisted and generated, which is usually called the recovery torque.This torque prompts the swing wheel to balance the position of the position.
The upper -point needle system rolls tightly in the original movement system and moves the timing of the time, and the needle is to correct the time of the clock.When the upper strip, the vertical and clutch wheels are in a meshing state.When dialing the needle, the clutch and the vertical wheel are taken off and meshing with the needle wheel.
