Background technique
In the use of modern motor, timing system more and more adopts chain transmission system, its high reliability, and accuracy can satisfy the requirement more and more higher to the distribution precision of modern motor.Modern engine speed is tending towards speed up, and meeting produces bigger engaging friction in the engagement process of chain and sprocket wheel, collision, and extruding, thus produce noise, vibrate, influence the working life and the transmission accuracy of complete machine performance and chain sprocket.
For this reason, an oil nozzle being installed on the engine timing chain drive system carries out oil jet lubrication to chain and is absolutely necessary.But so, with regard to needs individually on cylinder body or cylinder cap oil duct of processing come for oil nozzle carries out fuel feeding, increased that linkwork arranges difficulty and the cost of complete machine.
Summary of the invention
The purpose of this utility model is at existing the problems referred to above in the existing timing chain transmission system, and has proposed a kind of timing chain transmission system of directly timing chain being carried out from the chain tightener the motor of oil jet lubrication.
The purpose of this utility model can realize by following technical proposal: a kind of timing chain transmission system of motor, comprise air inlet sprocket wheel, exhaust sprocket, timing sprocket and the timing chain on the above-mentioned sprocket wheel, timing chain is provided with the controlling mechanism of can regulate timing chain tension force, it is characterized in that, described controlling mechanism comprises the chain tension rail that contacts with the timing chain cooperation, the chain tightener of control chain tensioning rail work is installed on the chain tension rail, and described chain tightener is communicated with lubricating oil duct in the motor.
Timing chain is meshed with air inlet sprocket wheel, exhaust sprocket and timing sprocket, and the elasticity of chain tension rail and chain tightener may command timing chain reduces the friction and wear between timing chain and the guide rail.Lubricant oil to the timing chain greasisng directly is ejected on the chain from chain tightener, draws oil in the lubricating oil duct that chain tightener just exists from motor originally.
In the timing chain transmission system of above-mentioned a kind of motor, an end of described chain tension rail is hinged by bolt and motor, and the other end is connected with chain tightener, and above-mentioned chain tightener may command chain tension rail freely rotates around bolt.When timing chain was lax, chain tightener acted on the end of chain tension rail, the chain tension rail was rotated, with the timing chain tensioning to the timing chain direction around bolt.
In the timing chain transmission system of above-mentioned a kind of motor, described chain tension rail is provided with oil groove, and the entry end of oil groove is communicated with the oil outlet of chain tightener, and the outlet end of oil groove is connected mutually with timing chain.Chain tightener draws oil from the lubricating oil duct of motor, the lubricant oil that flows out from the oil outlet of chain tightener is infused on the timing chain by oil groove, realizes lubricated to timing chain.
In the timing chain transmission system of above-mentioned a kind of motor, described chain tension rail adopts plastic materials to be made.The chain tension rail that plastics are made can fully reduce the weight of motor.
In the timing chain transmission system of above-mentioned a kind of motor, also be provided with guard rail on the timing chain between described air inlet sprocket wheel and the timing sprocket.
In the timing chain transmission system of above-mentioned a kind of motor, described guard rail adopts plastic materials to be made.The guard rail that plastics are made can fully reduce the weight of motor.
Compared with prior art, the used lubricant oil in the timing chain transmission system of this motor is to be sprayed onto on the timing chain from chain tightener, has omitted the chain greasisng nozzle, has made things convenient for layout, has saved cost.In addition, chain tension rail and guard rail all adopt plastic materials to be made, and have fully reduced the weight of motor.
