Gear Material: The gears are usually made of alloy steel. The alloy composition is carefully selected and the gears are heat - treated to achieve a high - strength and wear - resistant surface. Elements such as chromium (Cr), nickel (Ni), and molybdenum (Mo) may be included in the alloy to enhance the gears' hardness and toughness.
Gear Profile: The gears have a precision - machined involute profile. This profile ensures efficient fluid transfer between the gear teeth and minimizes internal leakage. The number of teeth and the gear size are optimized to achieve the desired flow characteristics and operating pressures. The gear diameter can range from [E] mm to [F] mm, and the gear width from [G] mm to [H] mm.
Shafts
Input Shaft: The input shaft is designed to connect to the power source, such as an electric motor or an engine - driven power take - off. It has a standard keyway or spline connection to ensure a secure and efficient power transfer. The diameter of the input shaft typically ranges from [I] mm to [J] mm, depending on the pump's displacement and power requirements. The length of the input shaft is designed to provide proper engagement with the motor shaft and any coupling used.
Output Shaft (if applicable): In some configurations, there may be an output shaft for additional mechanical connections. The output shaft's diameter and length are determined by the load it needs to drive and the requirements of the connected equipment.
