Problems solved by technology

However, the number and preset position of the several balance grains are fixed, and the weight of each balance grain is the same, so when adjusting the weight, it is impossible to reduce the weight at any position between any two balance grains, and it is also impossible to subtract non-integer grain balance weights. Due to the weight of the pellets, it is impossible to "fine-tune" the counterweight, so that the effect of adjusting the counterweight is not as expected

Abstract

The invention discloses an adjustable counterweight fan wheel and fan to solve a problem that the current fan wheel adjustment weight structure will weaken the fan wheel structure strength. The adjustable counterweight fan wheel comprises a hub, a shaft connected to the hub, a drive assembly connected to the hub, and an annular bearing disk disposed around the outer periphery of the hub. The annular carrier plate connects at least one of the hub and the drive assembly, which has a plurality of counterweight tanks arranged along the circumferential direction of the hub.

Description

technical field [0001] The invention relates to a fan and its components, in particular to a fan wheel with adjustable counterweight and a fan with the fan wheel. Background technique [0002] A general fan wheel is mostly combined with a rotating shaft at the center of the hub, and several fan blades are arranged on the outer peripheral surface of the hub; so that when the fan wheel is in operation, the several fan blades are rotated around the rotating shaft as the axis, thereby guiding Air flow. However, if the center of gravity of the fan wheel is shifted, shaking or vibration will occur during rotation, which will not only generate noise, but also accelerate the fatigue damage of the rotating shaft and shorten the service life of the fan wheel. [0003] For this reason, there are various existing fan wheels with adjustable counterweights; Several slots are provided on the axial end surface or the circumferential surface of the fan wheel, so that the counterweight can ...
