How to treat the shock absorber of a watch

Different shock absorbers have different effects on the realization of this shock absorption function. Many professional books on watches have theoretically expounded the working principle of shock absorbers. In short, the direction in which a watch is impacted or vibrated can be divided into three typical types:

(1) axial direction,

(2) radial,

(3) horizontal. The key point is that there is an inclined plane fit (about 45 degrees) between the shock absorber seat and the shock absorber support drill, which can produce sliding displacement. Shock absorber support drill is also commonly known as "shock absorber bowl".

When the shockproof bowl moves along the inclined plane of the shockproof seat, the shockproof spring is forced to bulge out and deform, and at the same time absorbs the impact energy from the swing shaft. Next, the thicker part of the lower end of the tenon tip of the swing shaft collides with the inner edge of the hole of the shock-proof base.

The diameter ratio of this part of the pendulum shaft is thicker and it can bear it. The shock absorber only protects the hairy shaft tip of the balance wheel and forces in all directions (including axial and radial impacts)

Basically, it is protected like this (structure, type and function of watch shock absorber)

Extended data

The core component of a mechanical watch is a hairspring. The balance spring acts as a spring, constantly absorbing = and releasing kinetic energy in the process of swinging, so that the balance spring keeps swinging.

The back and forth rotation of the hairspring is visualized as "Ma Zi". When winding a mechanical watch, it is equivalent to tightening this spring and then letting it release energy evenly to achieve the purpose of moving the hands.

The effective clearance of the hairspring directly affects the accuracy of the watch. As a circle, the hairspring has a red dot in the center. Generally, it is made of ruby, which has high hardness and is quite wear-resistant.

This thing is the tip of the pendulum shaft, and the thinnest part is about the diameter of an adult's hair, which is very delicate; The balance hairspring is of great mass and has leverage.

If there are no protective measures, once the watch shakes violently, the tip of the pendulum shaft will definitely break or shake. Once broken, maintenance is very troublesome, and it is difficult to walk accurately after repair.

At this time, shock absorbers are needed to absorb impact energy to protect this shaft. The key structure is that there is a 45-degree inclined plane between the shock absorber base and the support drill, and sliding displacement can occur between them.

When the drill bit moves along the inclined plane of the shock absorber seat, the spring of the shock absorber bulges out and deforms, thus absorbing the impact energy from the pendulum shaft. The shock absorber not only has the function of shock absorption, but also has the function of oil preservation. Between that drill frame and the shock absorb cover eye,

Add a proper amount of watch lubricant; So the deeper the fuel tank, the better (from the mechanical watch shock absorber). The shock absorber that can achieve the above functions is a good shock absorber.
