Problems solved by technology
However, the problem with this solution is that although the backlash between the camshaft idler gear and the camshaft driving gear can be guaranteed, it does not take into account the change in the engine compression ratio caused by the grouping of the cylinder head gaskets, so that the Engine installation and debugging are more troublesome

The invention relates to a gear backlash adjusting device for an engine, in particular to a device for adjusting backlash between a drive gear of a camshaft and an idle gear of the camshaft of the engine, which belongs to technical field of the internal combustion engine. A idle gear shaft for the camshaft and the camshaft are arranged on a bottom plate of a gear chamber; the drive gear of the camshaft is arranged on the camshaft; the idle gear of the camshaft is arranged on the idle gear shaft of the camshaft; and the idle gear of the camshaft is engaged with the drive gear of the camshaft. The device is characterized in that a positioning pin, a pressure plate and a fastening bolt are arranged on the idle gear shaft of the camshaft; and the pressure plate is fastened on the idle gear shaft of the camshaft by the fastening bolt. The positioning pin is positioned on a central connecting line between a pinion and the idle gear of the camshaft. The device saves the troubles that a gasket of a cylinder cover is needed to replace in order to adjust the gear backlash, does not influence the compression ratio of the engine, saves the time and improves the efficiency. The device has a simple structure and convenient adjustment.
Description
technical field [0001] The invention relates to a gear backlash adjustment device of an engine, in particular to a backlash adjustment device between a camshaft driving gear and a camshaft idler gear of the engine, and belongs to the technical field of internal combustion engines. Background technique [0002] The multi-cylinder engine is equipped with camshaft driving gear and several idler gears in the gear chamber of the engine body. If the camshaft idler gear is just installed on the side of the cylinder head, due to the error in the machining of the body and the error in the manufacturing of the cylinder head gasket itself, , making it difficult to ensure the backlash between the camshaft idler gear and the camshaft drive gear. The traditional solution is to group the cylinder head gaskets to compensate for the machining error of the body, so that the backlash between the camshaft idler gear and the camshaft drive gear meets the requirements. However, the problem with ...
