Description
technical field:
The utility model belongs to the lubricated field of high-power gear transmission, is specifically related to a kind of fueling injection equipment for the high-power transmission gear.
background technique:
High-power gear transmission is a kind of transmission device that is operated in high speed high pulling torque operating mode, and its characteristics are that between gear, transmission speed is high, and power is large, and output torque is large.Under this operating mode, usually adopt oil nozzle directly to the driving gear engagement place, to spray lubricant oil and carry out pressure lubrication, make oiling agent enter work place of gear engagement, form lubricating film and force mesh tooth face separately.Lubricant oil is sprayed into to gear teeth face with certain pressure, and there is not the stirring phenomenon in this mode, can in time the engagement heating be taken away, so body temperature of energy mesh control gear, select when correct, to be easy to realize the dynamic lubrication of elasticity oil film when lubricating oil viscosity, effectively reduce vibration and noise.In the Modern Gear design, top-priority is exactly oil jet lubrication, but different oil spout positions, lubricated effect is also different, there are three kinds of forms at modal oil spout position: lubricant oil sprays into engaging-in region, and lubricant oil sprays into engaging-out region, and lubricant oil sprays into engaging-in region and engaging-out region.Injection mode commonly used is the cylinder oil spout now, lubricant oil ejects from cylindric oil nozzle, the jet that forms cylindrical shape sprays to meshing zone, along gear line of contact direction, an oil nozzle is set at a certain distance, during this injection mode oil spout owing to forming cylindric jet, the lubricant oil be sprayed onto on Surface of action is inhomogeneous, easily forms the lubricated blind area on Surface of action, affects gear-driven efficiency.
the model utility content:
In order to meet high-power gear-driven requirement, improve the lubricating efficiency of gear transmission engagement place, the utility model provides a kind of fueling injection equipment for the high-power transmission gear.This device processing is simple, easy installation and removal, volume are little, lightweight, can be stably in a long term to the oil spout of gear engagement place, oil spout face is even, the lubricant oil utilization ratio is high.
The purpose of this utility model is achieved in the following ways: should be for the fueling injection equipment of high-power transmission gear, the technological scheme adopted is: comprise the injection tubing of being located at the gear top, oil spout base under described injection tubing is provided with and is tilted to and that communicate with it, oil nozzle under the end of oil spout base is connected and fixed and is tilted to, oil nozzle is by jet, fuel injection chamber and guide plate form, one end of described fuel injection chamber communicates with injection tubing, the other end of fuel injection chamber is communicated with jet, the outside of the lower end of oil nozzle in jet is provided with guide plate, described guide plate does not consist of on the inclined-plane in same plane upper and lower two-part, the inclined-plane of its underpart is slightly to the bending of jet place and directly over the gear engagement place.
The beneficial effects of the utility model are: should be for the fueling injection equipment of high-power transmission gear, adopt the injection tubing fuel feeding, supply the lubricant oil of certain pressure to injection tubing by oil pump, lubricant oil is finally sprayed by jet through the fuel injection chamber in injection tubing and oil nozzle.The lubricant oil of jet ejection sprays to point of mesh along two inclined-planes of guide plate, form fan-shaped pasta while when lubricant oil flows along guide plate, due to tension force between lubricant oil, acting on the ejection inclined-plane, spray to the point of mesh place and realize evenly lubricating, improve the lubricant oil utilization ratio.Its processing is simple, easy installation and removal, volume are little, lightweight, can be stably in a long term to the oil spout of gear engagement place, oil spout face is even, the lubricant oil utilization ratio is high.
the accompanying drawing explanation:
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is the sectional view along the A-A line in Fig. 1.
Fig. 3 is the structural representation of oil nozzle in the utility model.
embodiment:
Below in conjunction with each accompanying drawing, embodiment of the present utility model is described further:
Every pair of gear top is provided with an injection tubing 1, be provided with the nozzle holder 2 of some on injection tubing 1 along the line of contact direction of driving gear, nozzle holder 2 is welded on injection tubing 1, and fan-shaped oil film 9 width that form when between nozzle holder 2, distance is according to oil nozzle 3 oil spout determine.Oil nozzle 3 under the end of oil spout base 2 is connected and fixed and is tilted to, oil nozzle 3 consists of jet 6, fuel injection chamber 5 and guide plate 4, one end of fuel injection chamber 5 communicates with injection tubing 1, the other end is communicated with jet 6, jet 6 is cylindric, the outside of the lower end of oil nozzle 3 in jet 6 is provided with guide plate 4, guide plate 4 is not comprised of on the inclined-plane of two bendings in same plane upper and lower two-part, lubricant oil directive gear engagement place 7 slightly, to jet 6 places bending and directly over gear engagement place 7, is guided in the inclined-plane of its underpart.
The lubricant oil provided by oil hydraulic pump during work is by injection tubing entrance 8 injection tubing 1 of entering, lubricant oil is through the fuel injection chamber 5 in nozzle holder 2, through jet 6, be ejected on guide plate 4, lubricant oil is along guide plate 4 Jet with downward flow directions to the gear engagement place, lubricant oil is through guide plate 4 Jet with downward flow directions, because stopping with the tension force effect of lubricant oil of guide plate 4 makes downward jet flow be the fan-shaped gear engagement place 7 that sprays to, form fan-shaped oil film 9.
The utility model is compared than the cylindricality oil injection structure, can accurately lubricant oil be sprayed to the gear engagement place, and make lubricant oil can be ejected into uniformly on all points of mesh, can not stay blind area, improves the utilization ratio of lubricant oil.
