The invention discloses a drive sprocket lubricating and cooling device. According to the technical scheme, an intermittent oil sprayer and a continuous oil sprayer are fixed on a flange support; a first main oil passage and an intermittent spray cavity are formed in the intermittent oil sprayer, a pressure control valve is disposed between the main oil passage and the spray cavity, and two inclined oil nozzles are disposed on the side wall of the front end of the intermittent oil sprayer; a second main oil passage and a continuous spray cavity are further formed in the continuous oil sprayer, a main oil nozzle is arranged at the front end of the front end wall of the intermittent oil sprayer, and an auxiliary oil nozzle is arranged on the side wall of the intermittent oil sprayer. Compared with the traditional drive system having the sprocket lubricated by splashing oil supplied only by a camshaft, the drive sprocket lubricating and cooling device has the advantages that lubricating and cooling are better, inner mechanical noise of the sprocket can be reduced significantly, especially the design of the intermittent oil sprayer meets the requirement of an engine for lubrication and cooling at high rotating speed, and the intermittent oil sprayer is capable of stabilizing the pressure of the main oil passage pressure to avoid the fact that the oil pressure changes fast in a short time.
Description
technical field [0001] The invention belongs to lubricating components of an engine, in particular to a device for cooling and lubricating a transmission sprocket by means of machine oil injection. technical background [0002] With the competition in the engine industry market and technology, the requirements for various performance indicators of the engine are getting higher and higher. Noise reduction has become one of the main pursuit goals of various manufacturers, and the reduction of the noise of the sprocket drive system has attracted more and more attention. Compared with the traditional gear transmission, the structure of the sprocket is more flexible, which can reduce the number of idlers and provide more options for the development of engine technology. The lubrication of the gear transmission system is to spray the engine oil onto the gears through the camshaft. Compared with the sprocket drive, the space occupied by the gears meshing with each other is relativ...
