常用V带传动中,带轮为整体式,如图1所示,轮缘边槽的楔角(?)和宽度b是根据V带的型号来确定的。若工况改变,更换另一种型号的V带,由于节宽b_p不同,就要换另一种槽宽的带轮,这增加了备品备件数。笔者在某项目的带传动方案中,设计了一种槽宽可以任意调节的分体式带轮。在不同工况要求下,仅用一个带轮,可以实现多根不同型号V带的更换,有一物多用效果,现介绍如下:图2所示为双槽分体式V形带轮结构的示意图, Commonly used V-belt drive, the pulley as a whole, shown in Figure 1, the rim of the rim wedge angle (?) And width b is based on the V-belt model to determine. If the conditions change, replace the V-belt of another model, due to section width b_p different, we need to change the other width of the pulley, which increased the number of spare parts. The author in a project with the transmission scheme, designed a slot width can be adjusted split pulley. Under different working conditions, only one pulley can realize the replacement of a plurality of different types of V belts, and the utility model has the advantages of a multi-purpose and is introduced as follows: Fig. 2 shows a schematic diagram of a double-
