Embodiment Construction
[0017] The invention adopts an inner taper sleeve and an outer taper sleeve which cooperate with each other, the inner peripheral surface of the outer taper sleeve is a cylindrical surface, and the outer peripheral surface of the inner taper sleeve is a cylindrical surface. Under the external force of the nut, the two taper sleeves slide against each other to deform the taper sleeve. The cylindrical surface of the deformed outer taper sleeve presses the shaft, and the cylindrical surface of the deformed inner taper sleeve presses the inner hole of the object, thereby connecting the balance shaft and the object. Together, it is widely used in various objects that require dynamic or static balance, such as grinding wheels, impellers, belt wheels, etc., and is mainly used for dynamic and static balance of objects.
[0018] Such as figure 2 As shown, a balance shaft for dynamic balance or static balance includes a balance mandrel 1, and the middle part of the balance mandrel is a...

The invention provides a balance shaft for dynamic balance or static balance and a fixing method thereof. The balance shaft for dynamic balance or static balance and the fixing method thereof solve the problems that an existing balance shaft for balance is consuming in labor, low in efficiency, troublesome in operation and low in balance precision. The balance shaft comprises a balance central spindle, and the middle of the balance central spindle is a cylindrical plane. The middle of the balance central spindle is sleeved with an outer taper sleeve. A corresponding inner taper sleeve used for assembling workpieces is arranged on the outside of the outer taper sleeve. The balance central spindle is provided with a pressing nut used for locking the inner taper sleeve and the outer taper sleeve. The balance shaft enables the axis of a balanced object and the axis of the balance shaft to coincide easily, the positioning precision is improved, alignment is of no need, the balance precision is unchanged after the object is loaded and unloaded repeatedly, the positioning precision is improved, the balance precision is unchanged after the object is loaded and unloaded repeatedly, and operation is convenient.
Description
technical field [0001] The invention relates to a balance shaft, in particular to a balance shaft used for dynamic or static balance of an object and a fixing method thereof. Background technique [0002] There are many rotating objects that need to be balanced. Balance includes static balance and dynamic balance. Static balance is suitable for occasions with low precision, and can only detect the unbalance existing on one side of the object. Dynamic balance is suitable for occasions with high precision, and can detect the unbalance existing on both sides of the object. When doing balance, you need to use the balance shaft to penetrate the center hole of the object, fix the object and put it on the static balancer to check the static balance, and put it on the dynamic balancing machine to check the dynamic balance. [0003] Such as figure 1 As shown, at present, the balance shafts used for dynamic or static balance of objects all have a structure with a one-way co...
