The present invention relates to a new power transmission apparatus for a clutchless compressor, wherein the power transmission apparatus has a limiter assembly with a size capable of being minimized, thereby reducing and simplifying the entire size of the product of the power transmission apparatus and advantageously packaging the power transmission apparatus axially. According to the present invention for the above effects, a provided power transmission apparatus for a clutchless compressor comprises a pulley assembly with a pulley having a passage hole through which the driving shaft of the compressor passes, having a belt wound on the outer circumferential surface thereof, having multiple through-holes in the front circumference thereof, and having housing grooves in portions positioned on the rear circumference thereof and corresponding to portions with the through-holes respectively; a limiter assembly including a hub, a coupling part, and multiple fracture parts; a damper assembly including multiple dampers housed in the housing grooves of the pulley, and damper holders of which the parts penetrate the dampers, are exposed through the through-holes of the pulley, and provide coupling areas; and a cover plate formed to cover the limiter assembly, and coupled to the coupling part of the limiter assembly and the damper holder of the damper assembly respectively, wherein the hub of which one end is positioned inside the passage hole of the pulley is coupled to the driving shaft while positioned on the front surface of the pulley, the coupling part to be coupled to a target object is positioned on the other end of the hub, and the fracture parts connect the hub and the coupling part. |
