Description
Technical field
The present invention relates to a kind of multi-point radials for high-speed overload bevel gear to spray fuel nozzle, especially with respect to one kind
The injection oil supply structure cooling for high-speed overload bevel gear in gas-turbine unit.
Background technique
Gear lubrication mode select it is related to linear velocity, the foreign standards such as AGMA 2005-D03 recommend by table 1 select.
The selection of 1 lubricating system of table
| Pitch line velocity (m/s) | Eject position | Remarks |
| 15-25 | Advancing side | Lubrication be it is main, cooling is secondary. |
| 25-60 | Advancing side/nibble out side | Cooling be it is main, lubricating oil is enough |
| 60-100 | Nibble out side | Cooling is dominance, and lubricating oil will have more than needed |
| > 100 | Two-way oil spout | Advancing side lubrication nibbles out side cooling, it is high to nibble out effluent amount allocation proportion |
Research shows that: after linear velocity is more than 150m/s, in addition to carrying out two-way oil spout, it is also necessary to special lubrication be taken to set
For meter to solve oddity problem caused by high-speed overload, current relevant criterion both domestic and external does not provide solution.
High-speed overload bevel gear generally use it is engaging-in nibble out the two-way injection fuel system in side, advancing side is established oil film and is mainly risen
Lubricating action nibbles out cooling effect heat is taken away by lubricating oil in side, and spray site, which is located at, enters or exit region near engagement, spray
It penetrates direction and is directed generally towards pitch point along rolling tangential direction, the engaging-in spray site for nibbling out side is respectively 1, at present conventional knot
Structure can have problem under higher revolving speed and power operating condition, it may be assumed that
1) more high-power lower calorific value is big, but there are a upper limit values for the cooling capacity of oil jet lubrication, when calorific value is more than
When the upper limit value, it is further added by fuel delivery, has not been worked to gear teeth cooling.
2) windage effect is big under higher revolving speed, may injection less than exit engagement near region.
3) it is sprayed towards node, under certain conditions, gear wheel can stop the fuel feeding to pinion gear completely.
Summary of the invention
The purpose of the present invention:
For high-speed overload Bevel Gear Transmission, proposes a kind of multi-point radial injection oil supply structure, improve the cold of oil jet lubrication
But ability reduces windage adverse effect, and keeps lubricating oil injection unobstructed and can reach on gear wheel and pinion gear.
Technical solution of the present invention:
A kind of multi-point radial for high-speed overload bevel gear is provided and sprays fuel nozzle, the nozzle be provided with hollow oil pocket,
Enter oilhole and nozzle opening, hollow oil pocket is connected into oilhole and nozzle opening；Circumferentially positioned boss is formed in the end of the atomizer；
The nozzle opening includes that the first nozzle opening, the second basin oilhole and third nozzle opening, three nozzle openings are arranged at the end of atomizer
Portion；
In the nozzle axis projection, origin is projected as with nozzle centre axis, with the projection centre of circumferentially positioned boss
Line is standard projection line, and angle is 34.377 ° between the first oil spout centerline hole projection and the standard projection line；
Angle is 134.166 ° between the second oil spout centerline hole projection and the standard projection line；The third oil spout
Angle is 329.106 ° between centerline hole projection and the standard projection line；
The first oil spout centerline hole and nozzle centre axis institute in the planes, the first oil spout centerline hole and spray
Mouth central axis angle is 18.185 °；The second oil spout centerline hole and nozzle centre axis institute in the planes, described first
Oil spout centerline hole and nozzle centre axis angle are 59.138 °；Where third oil spout centerline hole and nozzle centre axis
In plane, the first oil spout centerline hole and nozzle centre axis angle are 73.237 °.
The main technical principle of multi-point radial injection lubrication is that it is cooling to nibble out side by 1 original spray site increase is more
It is a, it is sprayed simultaneously to gear wheel and pinion gear along tooth top direction, i.e., by increasing spray site, changing injection direction to improve cooling
Effect.
Direction nibbles out point, the multi-point injection mode of gear teeth tips makes the oil film of flank of tooth convection current forcing functions assemble-wash from
Cheng Duoci is established, and repeatedly accumulation takes away heat and improves total cooling capacity, breaks through the cooling capacity limit of single point injection.
Beneficial effects of the present invention:
Fuel delivery has a upper limit value to any gear drive, more than upper limit value fuel delivery to the coolings of the gear teeth not
It works, this upper limit value is known as effective fuel delivery, and the part for being more than is invalid fuel delivery.This technology can increase effective fuel feeding
It measures, control invalid fuel delivery, improve cooling effect.
Using certain transmission device bevel gear as application, carry out maximum effectively fuel delivery and calculate, as a result such as table 2, shown.Tooth
Taking turns ontology mean temperature reduces by 12 DEG C after using multi-point radial injection, reduces by 7%, if continuing growing spray site, gear
Temperature will be further compromised.Increase Amount of actual oil supply not working to reduction temperature more than after maximum effectively fuel delivery.
The comparison of 2 cooling effect of table
| Lubricating system | Maximum effective fuel delivery | Gear average temperature rising | Along facewidth maximum temperaturerise |
| Conventional single point injection | 1.169L/min | 50K | 75K |
| Multi-point radial injection | 1.559L/min | 38K | 57K |
