Engineering Machinery Parts Explained

Understanding the components of your machinery is key to proper maintenance. Here are a few examples:

• Swing Motor: The swing motor is located in the machine's upper structure and controls the rotation of the house. For example, a Sandvik DPi1500 drill rig swing motor (двигатель поворота), буровой станок Sandvik DPi1500 двигатель поворота, Sandvik DPi1500 drilling rig swing motor.

• Final Drive: The final drive is located on the track frame and provides torque to the tracks. For example, an Atlas Copco EC160 excavator final drive (конечная передача), экскаватор Atlas Copco EC160 конечная передача, Atlas Copco EC160 excavator final drive.

• Travel Motor: The travel motor is attached to the final drive and powers the movement of the machine. For example, an Epiroc MT42 mine truck travel motor (гидромотор хода), шахтный грузовик Epiroc MT42 гидромотор хода, Epiroc MT42 mine truck travel motor.

• Pilot Pump: A small hydraulic pump that supplies control pressure. For example, a Sandvik DP1500 pilot pump (пилотный насос), Sandvik DP1500 буровой станок пилотный насос, Sandvik DP1500 drilling rig pilot pump.

• Hydraulic Cylinder: A linear actuator used to push or pull. For example, an Atlas Copco MT42 hydraulic cylinder (гидроцилиндр), Atlas Copco MT42 горный грузовик гидроцилиндр, Atlas Copco MT42 mining truck hydraulic cylinder.

• Rotary Actuator: A device that converts hydraulic pressure into rotational motion. For example, an Epiroc DR412 rotary actuator (поворотный привод), буровая установка Epiroc DR412 поворотный привод, Epiroc DR412 drill rig rotary actuator.

• Track Adjuster: A component that maintains proper track tension. For example, a Caterpillar D8R track adjuster (механизм натяжения гусеницы), бульдозер Caterpillar D8R механизм натяжения гусеницы, Caterpillar D8R bulldozer track adjuster.

• Transmission Oil Pump: A pump that circulates oil in the transmission. For example, a Komatsu PC200-8 transmission oil pump (масляный насос коробки передач), экскаватор Komatsu PC200-8 масляный насос коробки передач, Komatsu PC200-8 excavator transmission oil pump.

• Torque Converter: A fluid coupling that transfers power from the engine to the transmission. For example, a Hitachi Zaxis 330 torque converter (гидротрансформатор), экскаватор Hitachi Zaxis 330 гидротрансформатор, Hitachi Zaxis 330 excavator torque converter.

• Engine Oil Cooler: A heat exchanger that cools engine oil. For example, a Volvo A40G engine oil cooler (маслоохладитель двигателя), самосвал Volvo A40G маслоохладитель двигателя, Volvo A40G dump truck engine oil cooler.
