Embodiment 1

[0031]A large quasi-square electromechanical pointer clock. The clock face installation adopts the floating installation of tension spring and compression spring. The shaft structure adopts polytetrafluoroethylene bushing and stainless steel shaft, which has passed the oil-free operation of the shaft hole for eleven years, providing a structural guarantee for the long-term operation of the movement without oil and maintenance. The transmission wheel train of the needle movement can choose to use the transmission wheel train with two speed ratios of 8HZ / S or 0.5HZ / S. The assembly precision of the minute wheel shaft of the needle movement movement is high, the shaft diameter runout is about 0.008mm, the radial load test is greater than 60 kg, and the minute hand with a circumference radius of 0.5 meters can be carried in a balanced linear motion under general closed conditions, and the power consumption of the needle movement is : 0.5HZ / S series DC4.8v, power consumption is les...

Abstract

The present invention relates to the movement structure, calendar display, clock face installation and rotating shaft structure. The movement structure consists of four parts including pulse stepped motor, pointer transmission wheel system, pointer setting mechanism and hour and day reporting trigger signal output mechanism. The minute wheel in backward design is set outside the back clevice assembly for saving space. The calendar display is a micro power consumption and large width one and the clock face is float installed with springs for lasting flatness. The rotating shaft structure is of self-lubricating corrosive and wear resistant material. The large clock of the present invention is not affected by power failure, whether and environment, and is corrosive, wear resistance, accurate, reliable and durable.

Description

technical field [0001] The invention relates to a large-scale electromechanical pointer clock, in particular to the needle-moving movement structure, calendar display, clock face installation and rotating part shaft structure material of a large electromechanical pointer clock. Background technique [0002] Generally, a clock whose pointer length and circumference radius is 0.5 meters or more is called a large clock. It is widely used in airports, stations, squares, banks, towers and other public places in various countries. The development of electronic technology has reformed the structure of traditional clocks and watches, but due to the limitations of electronic technology, the traditional mechanical structure of clocks and watches is still in use today. The manufacturing process of the needle movement is complex, the friction coefficient of the transmission is large, and there are problems such as easy corrosion, easy wear, and easy oil stagnation. In the case of high ...
