What are the benefits of dynamic balance?

Dynamic balance is a kind of technology to adjust balance or eliminate vibration by reducing or increasing weight of objects rotating at high speed It is also the most common method to balance transmission shaft (such as engine crankshaft or automobile tire, etc.) Once an object is raised to a predetermined speed, the computer reads the material provided by the sensor, and then adds or subtracts based on the recommended weight to maintain the object's balance Dynamic balancing is more popular than static balancing because of its high accuracy In most cases, an object can be perfectly balanced in one to two grams Mallory metal is most often added to the crankshaft to keep balance, which is a very expensive heavy metal The mallock metal is inserted into a pre drilled and held position, balancing by fine-tuning the weight By rotating the object or approaching the normal rotation speed, the dynamic balance copies the real-world performance to ensure that the object maintains the best performance when installed If there is no dynamic balance between the traditional shaft and crankshaft, the bearing will be extremely worn or even burnt out in a short period of time; the engine seat will be torn due to vibration, and the body will be damaged and separated The dynamic balance of tire can make the tire drive tens of thousands of kilometers under the condition of uneven wear In many machines, multiple components (often the entire assembly) are dynamically balanced The outboard boat engine adopts dynamic balance to minimize the vibration transmitted to the user; the balanced fishing line wheel provides the comfortable crank with the minimum vibration; even the high-end table electric mixer can keep stable and quiet through dynamic balance Although dynamic balancing must be used in any high-performance rotating application, this technology is also used in many commodity products with low performance For example, electric blenders and grills are dynamically balanced to provide more stable and durable operation In addition, saw, drill and lathe can also become durable tools after dynamic balance.
