Description
Technical Field
The invention relates to a dynamic balancing device, in particular to an automatic online dynamic balancing device. Belongs to the technical field of online dynamic balance of a main shaft.
Background
In the operation process of the mechanical transmission mechanism, the stable operation of the shafting is the weight of the stable operation of the transmission system, and as the rotation speed of the transmission system is more and more biased to be higher, the centrifugal force is directly proportional to the quadratic power of the rotation angular velocity of the shafting, so that how to efficiently avoid the vibration generated by the unbalance of the shafting becomes the important point of the design of the transmission system. Because unbalance faults such as broken teeth repair and the like occur after the large rotor rotates, the dynamic balance is difficult to disassemble, and the off-line dynamic balance is low in efficiency by stopping the balance weight after measuring the unbalance amount. A method of online dynamic balancing then occurs.
The core of the automatic on-line dynamic balance method is the design of a dynamic balance device also called a dynamic balance head. Currently, the common dynamic balance heads are designed into the following three types: the first type is a motor-driven mechanical dynamic balance head, namely, an electric signal is transmitted to a motor in the balance head through a slip ring, the motor changes the distance r between a counterweight and a rotation center through a lead screw, and the unbalanced quantity distribution condition of a rotating shaft can be changed due to the fact that the centrifugal force is in direct proportion to r. The second is a liquid spraying type balance head, the cavity is divided into a plurality of parts by sleeving the cavity on the rotating shaft, the same number of nozzles are matched, liquid is sprayed into the cavity through the spray head, the mass size and the distribution of the shafting are changed, and the unbalance amount is corrected due to the fact that the cavity and the liquid rotate along with the shaft. The third is an electromagnetic dynamic balance head, through a plurality of sliding discs, the sliding discs are provided with weights and can circumferentially rotate under external force, and the sliding discs are moved to a designated position through electromagnetic force to generate correction quality so as to improve unbalance.
The electromagnetic dynamic balance head has the most complex structure, and because the signal transmission and the driving force loading in the whole process are through electric signals, more sensors are needed to be equipped, and meanwhile, the use scene is more severe than mechanical and liquid spraying, for example, the patent of China patent No. CN200710185254.5 provides a high-speed main shaft on-line dynamic balance device. For the use environment of most mechanical transmission devices, the electromagnetic dynamic balance head is not suitable for use.
The liquid spraying type dynamic balance head is used as a simple and convenient mode in the three modes. The chinese patent No. CN201820033426.0 provides an integrated 3D molded on-line dynamic balance termination structure that greatly improves the sealability of the balance volume but substantially still improves the unbalance amount by changing the quality of the liquid in the cavity. When the cavity and the liquid rotate along with the shaft, the liquid has fluidity, so that the distribution condition of the liquid in the cavity is influenced when the speed is low or the vibration of the unbalanced quantity is large, the on-line dynamic balance result is fluctuated, and the liquid spraying type can only increase the dynamic balance of different in-cavity mass adjusting shaft systems through continuous liquid spraying in the continuous adjusting process, so that the quality of the rotating shaft is continuously increased. The motor-driven mechanical dynamic balance head is driven by a pure mechanical structure, and the motor drives the screw rod to enable the counterweight to be close to and far away from the rotation center, so that dynamic balance is adjusted. The device has certain advantages in reliability, but because the number of motors in the balance head is not easy to be excessive and the control precision of the screw is dependent on the lead of the screw and the rotation precision of the motors, a certain difference is formed between the control precision and the liquid spraying type.
The patent of China patent No. CN200510049231.2 provides a pure mechanical on-line dynamic balance head, combines the ideas of a liquid spraying type and a mechanical type, utilizes a pure mechanical device to control small steel balls to enter cavities with different phases and utilizes an electromagnet to adsorb, increases the mass of different phases of a shafting to adjust dynamic balance in the same mode as the liquid spraying type, and has more reliable structure compared with the liquid spraying type, but the control precision of the method is still poorer because of the larger mass of the steel balls.
In summary, the conventional liquid spraying type dynamic balance head has the problem of low adjustment accuracy of the mechanical dynamic balance head due to the influence of liquid fluidity and a continuously weighted shafting.
