XNUMX. Plum blossom coupling:
The quincunx coupling uses polyurethane plastic as the elastic element and the two-half coupling body is tightly combined (dispersed picture), and the main body is made of imported alloy aluminum. (Main picture) The middle polyurethane plastic element is made of a unique formula It is formulated to have abrasion resistance, high temperature resistance, good toughness, and stable and durable quality compared with ordinary plastic parts (comparison diagram of advantages and disadvantages). The plum-shaped body has six petals and eight petals, which can be customized according to customer requirements. The fixing method has a keyway.
XNUMX. The scope of application of plum-shaped coupling:
梅花形联轴器主要适用于起动频繁、正反转、中高速、中等扭矩和要求高可靠性的工作场合，例如：冶金、矿山、石油、化工、起重、运输、轻工、纺织、水泵、风机等。工作环境温度∶–35℃～80℃，传递公称扭矩25～12500Nm，许用转速1500～15300r/min。
