Description
Technical Field
The invention belongs to the field of low-carbon lubricating oil formulas and preparation methods thereof, and particularly relates to special-resistant grinding hydraulic oil and a preparation method thereof
Background
The hydraulic transmission is fluid transmission which uses liquid as a working medium and utilizes the kinetic energy of the liquid to transmit energy, and a hydraulic coupler, a hydraulic torque converter, an automatic transmission and the like are typical hydraulic transmission devices.
The impeller converts the rotation speed and torque input by a power machine (an internal combustion engine, a motor, a turbine and the like) and drives the working part of the machine through an output shaft. The hydraulic transmission oil interacts with impellers arranged on the input shaft, the output shaft and the shell to generate the change of momentum moment, thereby achieving the purpose of transmitting energy. Hydraulic transmissions differ greatly in principle, structure and performance from hydraulic transmissions that rely on hydraulic pressure energy to transfer energy. The input shaft and the output shaft of the hydraulic transmission are only connected by using liquid as a working medium, and the components are not in direct contact, so that the hydraulic transmission is non-rigid transmission. The hydraulic transmission has the advantages that: the said engine can absorb impact and vibration, has good overload protection, and even when the output shaft is blocked, the engine can still run without damage, and can start easily with load, and can implement automatic speed change and stepless speed regulation. Therefore, the hydraulic transmission can improve the power performance of the whole transmission device.
The hydraulic transmission oil is used as a working medium to transmit power, can be used for lubricating a bearing and a gear, is a carrier of slip heat and takes away heat, the performance of the hydraulic transmission oil is directly related to the reliability, the transmission efficiency and the service life of a hydraulic element, but because the extreme temperature difference of south and north of China is large, if the extreme low temperature of-54 ℃ is monitored in a desert river region, the common hydraulic transmission oil can meet the requirements of most hydraulic transmission systems but cannot meet the use under extreme climatic conditions, the common hydraulic transmission oil is difficult to start at low temperature due to too large kinematic viscosity, the use of a vehicle in certain low-temperature regions is limited, and the gear gluing phenomenon is easy to occur when the common hydraulic transmission oil is used reluctantly; under the high temperature environment, the power transmission of the equipment is powerless and delayed, and the equipment can be accompanied by shaking, noise and the like.
