Abstract

The invention provides a centering tool for an engine gearbox and an engine body. The centering tool for the engine gearbox and the engine body comprises a first supporting shaft, a second supporting shaft, a supporting disc frame and a pipe sleeve, a through hole is formed in the middle of a supporting disc frame, the pipe sleeve is of a hollow cylindrical structure, the periphery of one end of a crankshaft and the periphery of the upper end of the pipe sleeve are connected into the through hole in a sleeved mode, the periphery of the lower end of the pipe sleeve is sleeved with a gearbox main bearing hole, the first supporting shaft and the second supporting shaft are installed at the two ends of the supporting disc frame respectively and are arranged in parallel, and the lower end of the first supporting shaft and the lower end of the second supporting shaft are fixedly connected into two inert shaft holes respectively. According to the using method, when the engine body and the gearbox are assembled, errors of the positioning and mounting of a split type gearbox can be solved, the centering of the gearbox and an engine body main bearing hole can be achieved without combined machining and pin hole positioning, and the device is suitable for large marine diesel engines as well as diesel engines for split type gearboxes, engine bodies, and flywheel housings that require coaxiality.

Description

technical field [0001] The invention belongs to the technical field of engines, and in particular relates to a centering tool for an engine gearbox and a machine body. Background technique [0002] The structural parts of large marine diesel engines are mainly composed of body, cylinder head, crank connecting rod mechanism, and gas distribution transmission mechanism. The main function of the transmission mechanism is to drive the operation of each accessory pump to ensure the normal operation of the whole machine. The mechanism gear train is fixedly installed on the gearbox, the crankshaft is installed on the main bearing hole and is integrated with the crankshaft gear to drive the rotation of the accessory gears to provide the necessary fuel, lubricating oil and cooling system for the engine. The transmission mechanism separates the gear box from the machine body in order to meet the requirements of machine body processing technology and compactness of the whole machine, a...
