Precision Honing in the hydraulic system of the hydraulic pump is to provide pressurized hydraulic fluid to a hydraulic element, which is a pump. Its main function is to convert mechanical energy into a liquid pressure energy, hydraulic energy can easily control the pressure and flow, i.e. the machine speed and force. Output flow can be called according to need to adjust the variable displacement pump, flow can not be called adjustable metering pump. There is a pump with pressure regulating means. Hydraulic pump system used in a gear pump, vane pumps and piston three kinds. Gear pumps: smaller, simpler structure, strict cleanliness requirements for oil, the price is cheaper; But the shaft by the unbalanced force, serious wear and tear, leak bigger. Vane pump: divided double acting vane pump and single-acting pumps. The pump flow evenly, pulse small, smooth operation, low noise, operating pressure and high volumetric efficiency than gear pumps, complex structure than the gear pump. Pump: high volumetric efficiency, leakage small, can work under high pressure, mostly for high-power hydraulic system; but the complex structure, materials and processing high precision, expensive, high cleanliness requirements for oil. Hydraulic system design process, usually in the gear pump and the vane pump can not meet the requirements when using piston. Some of the hydraulic system also uses other forms of pumps, such as screw, etc., but the application as the above three common.
In addition to honing wheel Precision Honing machine for honing, but in shaving machine and lathe little modification can also honing, speed and amount of feed should be selected according to different specifications, Honing wheel generally moderate modulus gear can be 200-500 rev / min, and finally to feed 30-180mm / min. Been honing gear grinding capacity should be controlled at about 0.02mm, honing the shorter the better. Generally moderate modulus gear honing time should be about 2 minutes. In the honing process, the honing tool must not exceed the maximum stroke of the maximum width, in order to avoid damage to the honing wheel. Honing wheel more brittle material properties when used forbidden beat, to prevent bruising damage after use should be properly kept.
