Device for balancing precision mechanical turning systems

The invention relates to a device for balancing precision mechanical rotary systems of measuring instruments, optical devices and the like, with at least one balancing body that can be adjusted relative to the axis of the system.

Rotary systems of the above-mentioned type currently manufactured by the industry have balancing bodies in the form of counterweights on, which are adjustable in the longitudinal direction radially from the system of protruding arms. However, these balancing devices are expensive and require a high level of expertise to carry out perfect balancing. Furthermore, in practice, hard or Soft solder application on elements of precision mechanical turning systems balanced. Like the balancing devices with counterweights, the application of solder requires a larger installation space

for the system as well as an increase in its weight and inertia. The dosages when applying solder is Extremely difficult for the reasons already mentioned, so that less by frequent soldering, or by wearing asu large dosages, not only a significant amount of time is required for balancing, but also during the same damage to the highly sensitive system elements can occur «In addition, these are very often off made of a material that is not suitable for soldered connections.

The purpose of the invention is to create one that can be created with little effort and without essential specialist knowledge as well To create a quickly adjustable device for balancing precision mechanical turning systems, which eliminates the risk of damage to system elements. This is because of this

achieved that the balancing body is formed by a ring enclosing the axis of the system in the Abotand, which is in the ring plane is adjustable on all sides.

The device according to the invention is not only extremely simple from a structural point of view and can be attached to any rotating system with minimal space requirements, but also ensures its rapid balancing without the risk of damage to the system elements.

A useful further development of the invention is used
