Excavator power transmission route

Common excavator structures include: power unit, working unit, slewing mechanism, operating mechanism, transmission mechanism, walking mechanism and auxiliary facilities. The below power transmission route will help you to learn the power travel of excavator.

1.Travel power transmission route: diesel engine-coupling-hydraulic pump (mechanical energy is converted into hydraulic energy)-distribution valve-central rotary joint-traveling motor (hydraulic energy is converted into mechanical energy)-reduction gear box-drive wheel ——Track chain crawler——Realize walking

2.Slewing motion transmission route: diesel engine—coupling—hydraulic pump (convert mechanical energy into hydraulic energy)—distribution valve—swing motor (convert hydraulic energy into mechanical energy)—gearbox—slewing bearing—realize slewing

3.Boom movement transmission route: diesel engine—coupling—hydraulic pump (convert mechanical energy into hydraulic energy)—distribution valve—boom cylinder (convert hydraulic energy into mechanical energy)—realize boom movement

4.Stick movement transmission route: diesel engine—coupling—hydraulic pump (convert mechanical energy into hydraulic energy)—distribution valve—stick cylinder (convert hydraulic energy into mechanical energy)—realize stick movement

5.Bucket motion transmission route: diesel engine—coupling—hydraulic pump (convert mechanical energy into hydraulic energy)—distribution valve—bucket cylinder (convert hydraulic energy into mechanical energy)—realize bucket movement
