Description
The utility model relates to the time keeping instrument technical field, relates in particular to a kind of Machine core of turret clock gear train.
The turret clock that puts goods on the market at present and install and use has not only brought beautiful enjoyment to the city, and provides time showing, time service very easily for people.Yet because the design of Machine core of turret clock gear train itself still has many unreasonable parts, thereby also cause quality, the price of turret clock to exist suitable weak point: the first is because stepper motor directly drives the straight-tooth gear transmission, because rotating speed is fast, in the straight-tooth gear engagement process certain interval is arranged, produce high-frequency bump during running, not only stable working is poor, and noise can reach the 120-160 decibel, and gear very easily damages, directly influence runs well and maintenance cost.It two is because gear wheel is the transmission of many groups slows down, thereby complex structure, and volume is big, and manufacturing cost and selling price are higher.
The purpose of this utility model is to provide a kind of stable working, and noise is low, and is simple in structure, selling cost is moderate, the running reliable in quality reduces the Machine core of turret clock gear train of maintenance cost, can be suitable for the movement of the turret clock of public places uses such as city, harbour, harbour, station widely.
Another goal of the invention of the present utility model provides a kind of can the demonstration night, the transmission of reliable quality Machine core of turret clock, lighting mechanism.
The purpose of this utility model is achieved by following technical solution: a kind of Machine core of turret clock gear train, it comprises mutual meshed gears train on movement housing, stepper motor, transmission shaft, needle shaft and the transmission shaft, its special character is that a side of movement housing is established a stepper motor and is connected with worm screw, the worm gear of worm screw and its engagement constitutes input end first order reducing gear, and the gear that is arranged on the worm-wheel shaft is meshed with the gear drive train.
Compared with the prior art the utility model has the following advantages and good effect: first technical solution of the present utility model is directly to be attached thereto the worm drive that connects by stepper motor, reach and drive the worm gear that is meshed with worm screw, as input end first order gearing-down, because worm gear, worm geared characteristic, overcome the shortcoming of spur gear transmission in the prior art, make scheme described in the utility model have stable working, remarkable result that noise is low, detect through Shandong Province's clock and watch testing agency, its noise is below 40 decibels; Its two be the technical solution of the utility model by worm gear, worm screw as input end first order gearing-down, its reduction gear ratio is far longer than spur gear and slows down, thereby make gear train described in the utility model have one group of under drive gear of minimizing, movement housing volume is reduced, the texture ratio prior art is simple, parts reduce, and characteristics such as production cost and expense reduction help promoting the use of; It three is technical schemes described in the utility model, except using the worm and gear transmission as the input end first order gearing-down, when further having reduced the transmission of prior art spur gear with the transmission gear that is meshed, the gear on worm-wheel shaft has the bump shortcoming, make in the train transmission process steady, the running quality is more reliable, has also reduced the maintenance cost in the turret clock operational process simultaneously.It four is after scheme described in the utility model provides the end face electric installation, can make Machine core of turret clock described in the utility model realize the Presentation Function at night, and the reliable good effect of display quality.
