Lubricating oil fuel feed hole is interconnected, and is respectively equipped on the shell of ring gear two sides and is connected to lubricating oil fuel feed hole set by shell
Mounting hole, there is spray bar to be fixedly mounted on mounting hole, there is oil outlet connect with mounting hole in spray bar, oil outlet has
There are two oil outlet, an oil outlet is towards the mesh tooth face of ring gear, another oil outlet is towards planet wheel bearing.
The mounting hole is screw hole, and spray bar is set with its external screw thread spiral shell and is mounted on mounting hole.
The oil outlet has axial main oil outlet, and main oil outlet and mesh tooth face oil outlet and planet wheel bearing are fuel-displaced
Hole connection, mesh tooth face oil outlet are lateral setting and mesh tooth face of the oil outlet towards ring gear, planet wheel bearing oil outlet
With mesh tooth face oil outlet angle at an acute angle, and the oil outlet of planet wheel bearing oil outlet is towards planet wheel bearing.
Interconnected horizontal lubricating oil fuel feed hole, position are respectively equipped in the ring gear and the shell of ring gear two sides
In the top of the shell of ring gear and ring gear two sides.
The utility model has the beneficial effect that
1. the lubrication system for the planetary gear flank of tooth and bearing of the utility model design, by grease channel and spray
The unique design of oil pipe can realize the lubrication of the mesh tooth face and planet wheel bearing to planetary gear and ring gear respectively, and
There are oil jet lubrication in two sides.
2. the design utilizes ring gear and two sides housing design internal lubrication oil passage, lubricating oil external leakage is avoided
Risk.
3. usual planetary gear is immersed in gear-box oil sump when running to ring gear bottom, and runs to ring gear top
Then lack lubricating oil when portion.In the design, lubrication channel and spray bar are typically mounted on the top of ring gear, so that planet
Wheel can have sufficient oil jet lubrication when running at the top of ring gear.Therefore ring gear, planetary gear and planet wheel bearing can be reduced
Damage risk guarantees gear-box even running.
4. the design structure is compact, process low with assembly cost.
