Abstract

The invention discloses a novel hydraulic planetary speed regulating mechanism, and relates to the technical field of transmission devices. The novel hydraulic planetary speed regulating mechanism is mainly composed of a gear power dividing system, a hydraulic torque converter system, a planet gear system, a lubricating oil system and the like. A guide vane adjustable-type hydraulic torque converter is adopted in the hydraulic torque converter system. The hydraulic torque converter system is composed of a pump impeller, a turbine, a fixed guide wheel, an adjustable guide wheel, an executing mechanism and the like. The planet gear system belongs to a differential gear train and further consists of an inner gear ring, a planet carrier, a planet wheel and a sun gear. The novel stepless speed regulating transmission device operates according to the principle of 'power dividing'. Although the hydraulic torque converter of the power multi-branch hydraulic planetary transmission device is low in efficiency, the divided power is small, and therefore the efficiency of the complete device is high and the rated condition can reach about 95%.

Description

Technical field: [0001] The invention relates to the technical field of transmission devices, in particular to a novel hydraulic planetary speed regulating mechanism. Background technique: [0002] Improving energy utilization efficiency is an important direction for the development of scientific and technological equipment at present. my country's power plant equipment has been developing rapidly towards large-capacity, supercritical or ultra-super units. Power plant energy conservation is the main position for energy conservation and emission reduction in my country. When the thermal power plant is running, after the water in the boiler is heated and turned into steam, the feed water pump supplies water to the boiler and maintains a normal water level. The boiler feed water pump is an important auxiliary equipment in thermal power plants. Thermal power plants adjust the peak several times a day, and the steam temperature and steam pressure change with the unit load. It is...
