How to make a mechanical timer:
1. The mainspring is rolled by an elastic steel belt. When in use, the mainspring is wound up by manpower through the knob to store potential energy. When the mainspring relaxes, the stored potential energy is released, and power is transmitted to other parts of the timer.
2. Gear transmission mechanism The gear transmission mechanism is an intermediate mechanism that transmits the potential energy of the mainspring to the time control assembly. According to the different gear clutching methods when winding the mainspring, mechanical timers can be divided into spring tube type, pawl type and Small spring type three transmission mechanisms.
3. Time control component The structure of the time control component of the mechanical timer mostly uses one or two sets of cams to distribute the time. When the control cam rotates, its convex and concave positions are constantly changed, so that the contacts of the relevant contact reeds meet the design requirements. On or off to control run and stop. The mechanical timer is a single loop design
