Problems solved by technology

[0004] In the prior art, the opening of the lubricating oil nipple is generally located in the main oil passage of the engine. Taking lubricating oil in this way will cause a certain pressure drop to the lubricating system of the engine and increase the oil pumping burden of the oil pump, which is not conducive to engine lubrication.

Embodiment Construction

[0044] The embodiments described below with reference to the accompanying drawings are exemplary, and are only used to explain the present invention, and cannot be construed as limiting the present invention.

[0045] The embodiment of the present invention provides a timing chain system, please refer to figure 1 As shown, the timing chain system includes a first camshaft 3 and a first sprocket 2 that are coaxially arranged; the first sprocket 2 is equipped with a timing chain; the first sprocket 2 is sleeved on the first camshaft 3 One end is fixedly connected with the first camshaft 3. When working, the timing chain drives the first sprocket 2 to rotate, thereby driving the first camshaft 3 to rotate, which meets the engine's valve phase requirements.

[0046] As an improvement of the present invention, a sprocket oil hole 21 is provided radially symmetrically inside the first sprocket 2, and a camshaft middle hole 31 is axially provided inside the first camshaft 3. When install...

Abstract

The invention belongs to the field of engine lubricating system, and particularly discloses a timing chain system. The timing chain system comprises a first camshaft and a first chain wheel which arecoaxially arranged; the first chain wheel is equipped with a timing chain; the first chain wheel is sleeved at one end of the first camshaft and fixedly connected with the first camshaft; a chain wheel oil hole is radially symmetrically disposed inside the first chain wheel; a center hole of the camshaft is axially arranged inside the first camshaft; one end of the camshaft center hole away from the first chain wheel can be located at the end of the oil passage of the engine cylinder cover as the oil inlet to collect the engine oil; the end of one end of the camshaft center hole on which the first chain wheel is mounted is closed, an oil port is formed on the first camshaft corresponding to the chain wheel oil hole, and the center hole of the camshaft is communicated with the chain wheel oil hole through the oil port. The timing chain system ensures the effective lubrication of the timing chain system in the absence of a special lubricating oil nozzle, and also achieves the function ofreducing the pumping load of the oil pump.

Description

Technical field [0001] The invention belongs to an engine lubrication system, particularly a timing chain system. Background technique [0002] The timing chain system includes a camshaft, a driving sprocket, and a timing chain. When working, the timing chain drives the sprocket and drives the camshaft to rotate to meet the engine's valve phase requirements. In the whole process, the timing chain system is just a simple It has no other functions besides its driving mechanism. [0003] In the prior art, the lubrication of the timing chain system needs to be provided with a special lubricating nipple, and the lubricating nipple is directly facing the timing chain to lubricate it to prevent abnormal wear between the timing chain and the guide rail. [0004] In the prior art, the opening of the lubricating nozzle is generally located in the main oil passage of the engine. Taking lubricating oil in this way will cause a certain pressure drop to the lubrication system of the engine, incre...
