Problems solved by technology
At present, the material of the timing gear chamber is gray iron, the structure is relatively complex, and it is a thin-walled part, with an average wall thickness of about 7mm, especially between the middle gear hole of the timing gear chamber and the camshaft gear hole. Ribs, so shrinkage and deformation will occur here during processing, resulting in the failure of the intermediate gear to be installed in the gear chamber, resulting in the scrapping of the timing gear chamber workpiece and low yield

Embodiment Construction
[0011] Below in conjunction with accompanying drawing and embodiment, further elaborate the present invention.
[0012] like figure 1 and figure 2 Commonly shown, a timing gear chamber includes a timing gear chamber body 1. The timing gear chamber body 1 is provided with two end faces, and the two end faces are connected by side walls. The timing gear chamber body One end surface of 1 is provided with an intermediate pinion hole 2, and the adjacent part of the intermediate pinion hole 2 is provided with a camshaft gear hole 3, and there is a gap between the intermediate pinion hole 2 and the camshaft gear hole 3 for preventing The timing gear chamber body 1 is a deformed supporting part 4, and the two ends of the supporting part 4 are respectively connected to the two end faces of the timing gear chamber.
[0013] A supporting part 4 is added between the middle gear shaft hole and the camshaft gear hole on the timing gear chamber body. The supporting part 4 is a cylinder wi...

Abstract
The invention provides a timing gear chamber, relating to the technical field of automobile parts. The timing gear chamber comprises a timing gear chamber body, wherein the timing gear chamber body is provided with two end faces; the two end faces are connected through a side wall; one of the end faces of the timing gear chamber body is provided with a middle gear shaft hole and a camshaft gear hole; a support component which is used for preventing the timing gear chamber body from deforming is arranged between the middle gear shaft hole and the camshaft gear hole; and two ends of the support component are connected with the two end faces of the timing gear chamber respectively. According to the invention, the strength of the part between the middle gear shaft hole and the camshaft gear hole of the timing gear chamber is enhanced, the deformation is reduced, the problem that a middle gear cannot be installed because the timing gear chamber shrinks and deforms is avoided, thus the pass percent of timing gear chamber products is increased.
Description
technical field [0001] The invention relates to the technical field of auto parts, in particular to a timing gear chamber. Background technique [0002] The timing gear chamber is one of the important parts of the automobile engine, and its function is to ensure the gas distribution phase of the body and the fuel injection timing of the high-pressure oil pump. At present, the material of the timing gear chamber is gray iron, the structure is relatively complex, and it is a thin-walled part, with an average wall thickness of about 7mm, especially between the middle gear hole of the timing gear chamber and the camshaft gear hole. Ribs, so shrinkage and deformation will occur here during processing, resulting in the inability of the intermediate gear to be installed in the gear chamber, resulting in the scrapping of the timing gear chamber workpiece and low yield. Contents of the invention [0003] The object of the present invention is to overcome the above disadvantages an...
