Abstract
The utility model relates to a timing chain system, which is convenient in installation. A chain is connected with an intake cam shaft sprocket, an exhaust cam shaft sprocket, an engine oil pump sprocket and a crankshaft sprocket in a meshing manner, a chain tensioner is connected with a chain tensioning arm, the chain tensioning arm is connected with the chain in a close contact manner, a guide rail of the chain is connected with the chain in a contact manner, a chain mounting support is connected with the chain in a contact manner, an intake cam shaft sprocket mark pit is arranged on the intake cam shaft sprocket, an exhaust cam shaft sprocket mark pit is arranged on the exhaust cam shaft sprocket, and a crankshaft sprocket mark pit is arranged on the crankshaft sprocket. The timing chain system has the advantages of novel structure, installation in a labor-saving and time-saving manner and capability of increasing production efficiency of an engine.
Description
Technical field
The utility model belongs to a kind of installation timing chain system easily.
Background technique
At present, in the engine arrangement design, the timing chain system of motor is made up of crankshaft sprocket, admission cam shaft sprocket wheel, exhaust cam shaft sprocket wheel, oil pump sprocket wheel, chain, chain tensioning device, chain tension arm, chain guide, chain mounting bracket etc.The timing chain system need adopt special tool when installing, at first the inlet and outlet camshaft is fixed on a cylinder top dead center position during assembling with special tool, then turning crankshaft is fixed on a cylinder top dead center position with special tool with bent axle, put chain, open the stretcher tension chain, the dismounting special tool, at this moment timing chain system assembling finishes, this fit, the time of usefulness is longer, influences engine production efficient.
Summary of the invention
The utility model provides a kind of timing chain system, to solve the problem that the timing chain system assembling time spent is long, influence engine production efficient.
The technological scheme that the utility model is taked is: chain and admission cam shaft sprocket wheel, exhaust cam shaft sprocket wheel, oil pump sprocket wheel, crankshaft sprocket are connected with a joggle, chain tensioning device is connected with the chain tension arm, the chain tension arm closely contacts with chain and is connected, chain guide is connected with the chain contact, the chain mounting bracket is connected with the chain contact, admission cam shaft sprocket wheel mark pit is arranged on the admission cam shaft sprocket wheel, exhaust cam shaft sprocket wheel mark pit is arranged on the exhaust cam shaft sprocket wheel, crankshaft sprocket mark pit is arranged on crankshaft sprocket.
The utility model has the advantages that novel structure, the installation of timing system is saved time, laborsaving, improved engine production efficient.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Chain 9 is connected with a joggle with admission cam shaft sprocket wheel 1, exhaust cam shaft sprocket wheel 2, oil pump sprocket wheel 4, crankshaft sprocket 6, chain tensioning device 8 is connected with chain tension arm 7, the chain tension arm closely contacts with chain and is connected, chain guide 3 is connected with chain 9 contacts, chain mounting bracket 5 is connected with the chain contact, admission cam shaft sprocket wheel mark pit 10 is arranged on the admission cam shaft sprocket wheel, exhaust cam shaft sprocket wheel mark pit 11 is arranged on the exhaust cam shaft sprocket wheel, crankshaft sprocket mark pit 12 is arranged on crankshaft sprocket.
The utility model is the pit of labelling in crankshaft sprocket, admission cam shaft sprocket wheel, exhaust cam shaft sprocket wheel part the place ahead, these marks are finished by parts supplier, main engine factory need not use special tool during assembling, at first rotate directly over the intake and exhaust cam axle places admission cam shaft sprocket wheel, exhaust cam shaft sprocket wheel mark, chain is installed, then rotary crankshaft makes and opens stretcher and make chain system be in tensioning state.
