Abstract
This utility model relates to a kind of durable wind turbine gearbox injection loop, and the circular radial side face along described injection loop ring body is provided with oil groove and a dowel hole, and described dowel hole is arranged on described oil groove one lateral edges；Being interval with multiple nozzle opening in described oil groove, described nozzle opening is arranged along described injection loop radial direction；Described dowel hole is positioned at described nozzle opening side;Reduce the volume of injection loop, increase the oil pocket between motor side two bearings, by oil in oil pocket to bearing lubrication, it is to avoid the problem having influence on bearing lubrication because injection loop is anti-loaded.Add the circumferentially positioned of injection loop, it is therefore prevented that the problem affecting bearing lubrication because of oil sealing surface abrasion.
Description
Technical field
This utility model relates to a kind of box bearing lubrication injection loop, a kind of durable wind turbine gearbox oil spout
Ring.
Background technology
Existing gear-box injection loop typically uses the structure that two side bearings are taked forced feed lubrication, and this structure needs to account for
According to space big so that the oil pocket between two bearings diminishes, trapped fuel amount reduce；Owing to the bearing arrangement of injection loop both sides is different,
The position of the opened oilhole in this injection loop both sides is the most different, if anti-loaded, oil spout can be made to be obstructed, and reduces the lubrication merit to bearing
Energy.And this structure injection loop does not has circumferentially positioned, if rotating in casing, producing abrasion with box body hole, can affect
Oil sealing surface, the impact lubricant effect to bearing.
Utility model content
This utility model purpose is to provide a kind of durable wind turbine gearbox injection loop to overcome the deficiencies in the prior art,
Ensure bearing lubrication effect, improve bearing operational reliability.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of durable wind turbine gearbox injection loop, edge
The circular radial side face of described injection loop ring body is provided with oil groove and a dowel hole, and described dowel hole is arranged on described oil groove
On one lateral edges；Being interval with multiple nozzle opening in described oil groove, described nozzle opening is arranged along described injection loop radial direction；Institute
State dowel hole and be positioned at described nozzle opening side.
Improving further as this utility model, the bore dia of described dowel hole is the four of described oil groove axial width
/ mono-.
Due to the utilization of technique scheme, this utility model compared with prior art has the advantage that
This utility model provides a kind of durable wind turbine gearbox injection loop, reduces the volume of injection loop, increases motor
Oil pocket between the two bearings of side, by oil in oil pocket to bearing lubrication, it is to avoid have influence on bearing lubrication because injection loop is anti-loaded
Problem.Add the circumferentially positioned of injection loop, it is therefore prevented that the problem affecting bearing lubrication because of oil sealing surface abrasion.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings technical solutions of the utility model are described further:
Accompanying drawing 1 is one of the present utility model durable wind turbine gearbox injection loop structural representation；
Accompanying drawing 2 shows structural representation for one of the present utility model durable wind turbine gearbox injection loop structure B-B to cuing open；
Accompanying drawing 3 is dowel hole and nozzle opening structure in one of the present utility model durable wind turbine gearbox injection loop structure
Position partial schematic diagram.
Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment detailed description that this utility model is made.
One described in the utility model durable wind turbine gearbox injection loop structural representation as shown in accompanying drawing 1,2,3,
Circular radial side face 2 along described injection loop 1 ring body is provided with oil groove 3 and a dowel hole 4, and described dowel hole 4 is arranged on
On oil groove 3 one lateral edges；Being interval with multiple nozzle opening 5 in oil groove 3, nozzle opening 5 is arranged along injection loop 1 ring body radial direction；
Dowel hole 4 is positioned at nozzle opening side；The bore dia D of dowel hole 4 is 1/4th of oil groove 3 axial width L；Dowel hole
The interval S of distance wherein side nozzle opening is between the D and the D of 6 times of 2 times；High-precision axial width L, bore dia D and
Away from S distance design, effectively slacken the stress intensity that in work process, injection loop bears, while location, preferably ensure profit in oil groove
The fluency of lubricating oil and without hindrance impenetrability；In apparatus structure, injection loop 1 acts on dowel hole 4 by limit screw and alignment pin
The upper realization location to injection loop 1, the injection loop structure that this utility model patent proposes may be used for the high speed of wind turbine gearbox
The lubrication of level motor side bearing；Injection loop is arranged between high speed level motor side two bearings, matches with dead eye, by location
Sell its circumference stop, prevent abrasion；During work, lubricating oil flows in the oil pocket between two bearings countershaft through casing, injection loop
Hold and be lubricated, verify that there is good lubricant effect through actual tests.
When this utility model structure is specifically applied, above is only concrete exemplary applications of the present utility model, new to this practicality
The protection domain of type does not constitutes any limitation；The technical scheme that all employing equivalents or equivalence are replaced and formed, all falls within
Within the scope of this utility model rights protection.
Claims (2)
1. a durable wind turbine gearbox injection loop, it is characterised in that the circular radial side face along described injection loop ring body is provided with
