Description

A kind of lubricating structure of timing chain system
Technical field
The utility model relates to Automobile Motor Design field, particularly a kind of lubricating structure of timing chain system.
Background technique
The timing system of motor generally adopts belt drives and chain drive two kinds of modes, and current most of motor all adopts chain drive, main because chain-drive timing chain system is identical with engine life, can maintenance-free, good reliability.But timing chain system operationally needs to lubricate timing component, adopt to offer nozzle opening on hydraulic tensioner before always, hydraulic tensioner is used to lubricate timing system, but for the motor of some special operation conditions, only open nozzle opening by hydraulic tensioner to carry out lubrication and can not ensure lubrication effect, chain can be caused to extend because of insufficient lubrication.
Model utility content
The utility model technical issues that need to address are to provide a kind of lubricating structure of timing chain system, can carry out sufficient lubrication to reach under working conditions of different engines to timing chain system, prevent chain from causing because of insufficient lubrication extending.
In order to solve the problems of the technologies described above the technical solution of the utility model be, a kind of lubricating structure of timing chain system, comprise cylinder body, be arranged on the main oil gallery in cylinder body, cylinder body is furnished with timing chain, described cylinder body is furnished with the crankshaft sprocket engaged with timing chain, described cylinder body is also provided with installation base, be provided with mounting hole in described installation base, described mounting hole is built with oil nozzle, and described oil nozzle communicates with main oil gallery.
Described oil nozzle is by assembly department, limited part and oil spout portion composition, assembly department, is cylindric with oil spout portion, limited part is semi-cylindrical, assembly department is connected with oil spout portion by limited part, and the diameter of limited part is greater than the diameter in assembly department and oil spout portion, and oil nozzle inside is provided with oil duct, oil duct has oil inlet hole and nozzle opening, oil inlet hole is arranged on assembly department, and nozzle opening is arranged in oil spout portion, and oil inlet hole communicates with main oil gallery.
Described mounting hole inwall is provided with limiting stopper, and limited part is provided with confined planes, and confined planes and limiting stopper are fitted and arranged.
The utility model compared with prior art, main oil gallery in cylinder body, cylinder body is provided with timing chain, described cylinder body is provided with the crankshaft sprocket engaged with timing chain, described cylinder body is also provided with installation base, mounting hole is provided with in described installation base, oil nozzle is provided with in described mounting hole, described oil nozzle communicates with main oil gallery, timing chain can be made to lubricate sufficient, prevent timing chain from extending because insufficient lubrication weares and teares long, reduce the risk that tooth occurs to jump motor, ensure the normal operation of motor, oil nozzle is easily arranged, cost is lower, be convenient to install, high lubricating effect, save timing system arrangement space.
Accompanying drawing illustrates:
Below in conjunction with the drawings and specific embodiments, further description is made to the utility model;
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model oil nozzle structural representation;
Fig. 3 is the utility model confined planes structural representation;
In fig. 1-3,1, cylinder body, 2, installation base, 3, timing chain, 4, crankshaft sprocket, 5, assembly department, 6, limited part, 7, oil spout portion, 8, oil inlet hole, 9, nozzle opening, 10, oil nozzle, 11, limiting stopper, 12, confined planes.
Embodiment:
As Figure 1-3, a kind of lubricating structure of timing chain system, comprise cylinder body 1, be arranged on the main oil gallery in cylinder body 1, cylinder body 1 be furnished with timing chain 3, described cylinder body 1 is furnished with the crankshaft sprocket 4 engaged with timing chain 3, described cylinder body 1 is also provided with installation base 2, be provided with mounting hole in described installation base 2, be provided with oil nozzle 10 in described mounting hole, described oil nozzle 10 communicates with main oil gallery.
Described oil nozzle 10 is by assembly department 5, limited part 6 and oil spout portion 7 form, assembly department 5 and oil spout portion 7 are cylindric, and limited part 6 is semi-cylindrical, and assembly department 5 is connected with oil spout portion 7 by limited part 6, the diameter of limited part 6 is greater than the diameter in assembly department 5 and oil spout portion 7, oil nozzle inside is provided with oil duct, and oil duct has oil inlet hole 8 and nozzle opening 9, and oil inlet hole 8 is arranged on assembly department 5, nozzle opening 9 is arranged in oil spout portion 7, and oil inlet hole 8 communicates with main oil gallery.
Oil inlet hole 8 communicates with the main oil gallery of cylinder body 1, gets oil from cylinder body main oil gallery, when the engine runs, endlessly oil flow to oil nozzle oil inlet hole from cylinder body main oil gallery and spray to timing chain and crankshaft sprocket from the nozzle opening 9 of oil nozzle engage position.
Described mounting hole inwall is provided with limiting stopper, and limited part is provided with confined planes, and confined planes and limiting stopper are fitted and arranged.Such design, confined planes and limiting stopper fit tightly, can prevent oil nozzle oil spout direction not to and the chain greasisng effect caused is bad.
Before use, first the limited part of oil nozzle is alignd with the installation base on cylinder body, then with "painted-face" character in opera oil nozzle knocked in the mounting hole on the installation base of cylinder body.When the engine starts, machine oil enters into oil nozzle oil inlet hole by the oil duct of cylinder body, then enters lubrication nozzle opening by oil nozzle oil inlet hole, and oil inlet hole is communicated with lubrication nozzle opening.Along with engine oil pressure constantly raises, under pressure, machine oil is from the ejection of lubrication nozzle opening, thus lubrication timing chain and crankshaft sprocket, reduce the frictional force between chain and sprocket wheel.
The utility model has the advantage of, timing chain can be made to lubricate sufficient, prevent timing chain from extending long because of insufficient lubrication wearing and tearing, reduce the risk that tooth occurs to jump motor, ensure the normal operation of motor.
This oil nozzle is fixed on engine cylinder-body in the mode press-fited, the limited part on it can be relied on to align with the installation base on cylinder body, control the operative orientation of oil nozzle spout, making it be operated in suitable needs in regions of lubrication, oil nozzle is easily arranged, cost is lower, be convenient to installation, high lubricating effect, saves timing system arrangement space.
