GB/T 5015-2003

GB/T 5015-2003 specifies the technical requirements, dimensions, and performance criteria for gear couplings with pin elastomers, which are used to transmit torque between rotating shafts while accommodating minor misalignments and damping vibrations. This standard is applied in mechanical transmission systems, particularly in heavy machinery such as mining equipment, metallurgical mills, and industrial pumps, where reliable coupling under high-load and shock conditions is essential. It ensures interchangeability and safety in design and procurement for manufacturers and engineers in China's mechanical engineering sector.
