High-reliability transmission belt tensioning clutch control mechanism

Abstract

The utility model discloses a high reliability transmission belt tensioning clutch control mechanism, including oil cylinder, elastic compensation pole group, long and short edge U type hanging axle, swing arm, tensioning wheel, support plate welding and three fixed base, oil cylinder articulates first fixed base and connects elastic compensation pole group, and pole group vertical articulates swing arm, and swing arm middle part hinged second fixed base, and its end installs tensioning wheel and is articulated with U type hanging axle short edge, support plate welding is by support plate body and three -segmented bending pivot and is composed, and support plate is articulated with U type hanging axle long edge, and pivot tail section is assembled in support plate mounting seat, when oil cylinder stretches out, tensioning wheel is pressed tightly transmission belt, and support plate is separated from belt and realizes power transmission, when oil cylinder is retracted, tensioning wheel lifts, and support plate is on top transmission belt and makes it separate from driving pulley. The mechanism is through single U type hanging axle linkage tensioning wheel and support plate, and elastic compensation pole buffering belt expansion and contraction impact, and relies on double separation structure to prevent the belt linkage, and the structure is simple, and the operation reliability is high.
