Abstract
The invention provides an engine oil pump provided with an idle wheel, which is low in machining cost and high in location efficiency. The engine oil pump provided with the idle wheel comprises a pump body, a main shaft, a pump oil gear, a pump cover, a transmission gear, the idle wheel, an idle wheel shaft and a set screw, wherein the pump oil gear and the transmission gear are installed on the main shaft; the idle wheel is installed on the idle wheel shaft; a through hole is arranged in the idle wheel shaft; the set screw penetrates through the through hole in the idle wheel shaft to install the idle wheel shaft on the pump cover; and a gap of 1-2.5mm is formed between the set screw and the hole wall of the through hole. The invention further provides an idle wheel assembly fixture provided with the engine oil pump. Because a location pin (hole) structure of the idle wheel is cancelled, the cost is greatly reduced; and meanwhile, the certain gap is formed between the set screw and the hole wall of the through hole, in this way, the idle wheel shaft is enabled to freely move in a certain range, and the set screw can be screwed when the idle wheel shaft moves to a proper position, so as to fix the idle wheel shaft on the pump cover.
