Clock split axis shock escapement

Abstract

The invention discloses an escapement for the impact of a split shaft of a clock, and the escapement comprises an escapement fork, an escapement wheel, a balance wheel disc, and an impact disc. The escapement fork is disposed on a central spindle in a swinging manner, and is provided with a left locking tooth fork tile and a right locking tooth fork tile, wherein the right locking tooth fork tile is provided with a positioning rod. The escapement wheel is provided with an upper tooth ring and a lower tooth ring, wherein the upper and lower tooth rings are fixed coaxially and have the same diameter. Upper inclined teeth and lower inclined teeth are sequentially arranged on a horizontal projection plane in an interlaced manner. The external periphery of the balance wheel disc is provided with a lower fork tile and an upper fork tile, and the balance wheel disc is provided with a disc nail which is used for driving the positioning rod to operate. A central shaft of the impact disc is provided with a return mechanism, and an outer side surface is provided with a transmission mechanism. According to the invention, a gear tooth ring and the lower tooth ring have the same size, thereby enabling the left and right locking tooth fork tiles to have the same impact distance, and enabling the pace to be stable. The friction balance of the escapement fork cannot cause a condition that one locking tooth fork tile is excessively worn. The same impact distance can effectively avoid a push-out fault happening between the inclined teeth and the fork tiles, and prevents the hidden stop.

Description

technical field [0001] The invention relates to a mechanical clock, in particular to a split shaft impact escapement for the clock. Background technique [0002] There are two main types of escapement for modern mechanical watches, one is the traditional lever escapement, and the other is the coaxial escapement invented by Omega at the end of the 20th century. [0003] The coaxial escapement is theoretically more advanced than the lever escapement. It changes the friction drive of the lever escapement into an impact drive, which reduces the excessive consumption of kinetic energy due to friction. The impact fork does not need or requires less lubricating oil. More reliable and accurate. The diameters of the helical teeth of the upper and lower layers of the coaxial escapement are different. The diameter of the upper helical teeth is smaller, while the diameter of the lower helical teeth is larger, and has the following defects: [0004] (1) The pallet fork of the coaxial e...
