The invention discloses a mechanical supercharger which comprises a gear transmission member used to transfer power, wherein the gear transmission member comprises a transmission shaft, a first transmission gear assembled on the transmission shaft, and a second transmission gear; the transmission shaft is connected with a crankshaft, and is sleeved with a supercharger impeller shaft; the supercharger impeller shaft is sleeved with a supercharger impeller and a diffuser; the diffuser is fixed to a casing; and the second transmission gear is assembled on the diffuser, and is engaged with the first transmission gear and the supercharger impeller shaft, in order to transfer the power transferred to the first transmission gear by the transmission shaft to the supercharger impeller shaft with drive the supercharger impeller to rotate. The mechanical supercharger adopts the gear transmission member to transfer the power, so that when the mechanical supercharger transfers the power, the transfer power, the transfer speed and the transfer ratio are high; the transmission efficiency is high; the structure is compact during mounting; the operation is stable and reliable; the service life is long; the transmission smoothness is high; and the transfer movement is accurate and reliable.
Description
technical field [0001] The invention relates to the field of aero-engines, in particular to a supercharger. Background technique [0002] The supercharger is used in both aviation piston engines and vehicle piston engines. Compressing air through the supercharger can increase the air density and pressure in the intake manifold and increase the air filling volume in the cylinder, thereby improving the engine capacity. The liter power improves the economy of the engine. [0003] The transmission mechanism of the supercharger generally adopts a belt drive, which is connected to the crankshaft pulley through the belt, and indirectly transmits the torsional motion of the crankshaft to the supercharger to achieve the purpose of supercharging. [0004] Due to the small difference in the size of the pulleys of various engines and the limited engine installation space, the working speed of the supercharger using the belt drive is low (far below 30,000r / min), and the transmission eff...
