[Chybí předmět]The gear train of the watch
href="http://www.sevenfridayshop.co.uk/">Sevenfriday replica, especially the main drive wheel, is widely used in akind of so-called arc tooth shape. The tooth profile is wiring evolved, for pure
cycloidal tooth profile processing is difficult, therefore, use circular arc toreplace cycloid, also called modified cycloid tooth shape,
Aliexpress rolex watches [www.alibaba-watches.com] can make the gear shaft with a minimum of 6 teeth, and thus in wheel teeth without too much can be achieved
under the condition of large transmission ratio, the diameterreducing

center on high frequency and extremely strong in the
Replica Patek Philippe [www.evwatches.com]. The transmission
efficiency is relatively high, can reach about 95 %. Since the size of the watch
machine is small, the energy stored in the box is not large. If the energy loss is
too large, it will directly affect the quality of the watch. The sensitivity of
machining error is greater. If the tooth shape error and the center distance error,
it will cause the change of the meshing characteristic. Since the tooth shape is
determined by a pair of gear and modulus of meshing, the number of teeth and
modulus is different, and the used hob and milling cutter are not the same.
