Fan rotor balance structure

Abstract

The invention provides a fan rotor balance structure. The fan rotor balance structure comprises a fan wheel and a balance body, wherein the fan wheel comprises a hub and a plurality of blades which are arranged on the outer peripheral side of the hub, and the hub is provided with a top wall connected with one side wall; an unbalanced part is arranged on the top wall or the side wall in a selectivemode, and furthermore, is located on one side of a symmetry axis of the hub; and the balance body is arranged on the unbalanced part so as to balance a fan rotor.

Description

technical field [0001] The invention relates to a fan rotor balance structure, in particular to an effect that can quickly balance the rotor and save costs. Background technique [0002] With the development of computer technology, when the operating clock and performance of the internal components of the computer gradually increase, the power consumption and heat generated by the internal components of the computer will also increase. In order to reduce the internal temperature of the casing and help heat dissipation, high-performance components are required. The heat dissipation mechanism is used to help remove the heat generated by the internal parts of the case, so as to avoid the high temperature inside the case, which will affect the life of the internal parts or cause unstable operation. In the field of heat dissipation for the entire system, the cooling system composed of fans and heat sinks is still the mainstream of cooling computers in the industry, and the fan pa...

Problems solved by technology

And in order to achieve the required vibration level specifications, it is often difficult to control the gram weight of the required balance soil because the weight of the balance soil is too small (for example, milligrams) to repeatedly replenish the balance soil until the convergence reaches the specification, so it takes longer to derive the balance correction rotor. Time is needed to obtain better balance quality, and it needs to invest a lot of manpower and balance equipment to maintain a considerable production capacity, which will cause problems of increased production costs and excessively long balance working hours

[0004] At present, the operation of the rotor dynamic balance correction test is still in the stage of manual operation. According to the rough test results and the position of the unbalance point on the rotor irradiated by the projected light, the staff performs manual counterweight (that is, supplementary balance) or manually Balance correction for deweighting (that is, balance reduction). For example, the staff will roughly project the position of the unbalance point on the rotor through their eyes, and then lift the entire rotor away from the fan rotor dynamic balancing machine for counterweight or de-weighting. When balancing the weight, there is no projection light on the rotor to illuminate the position of the unbalanced point at this time, so the staff can only vaguely remember the position of the unbalanced point of the rotor with the eyesight of the staff, and then carry out the counterweight or de-weighting process of the rotor , so to complete the dynamic balance correction of a rotor, it is often necessary to repeat the test and counterweight or de-weight processing many times, which leads to the problems of low production efficiency and low balance accuracy
