Abstract
The utility model discloses a reduction gear bearing lubricating structure relates to the reduction gear field, provides a lubricated effectual reduction gear bearing lubricating structure. Reduction gear bearing lubricating structure includes retarder housing, pinion and gear wheel all install on retarder housing through the gear shaft, pinion and gear wheel meshing, be provided with pinion bearing between the gear shaft of pinion and the retarder housing, still include the oil blocking piece, the oil blocking piece is located between pinion and the gear wheel and is connected with retarder housing, the oil storage tank has on the oil blocking piece, the top of oil storage tank is higher than pinion bearing bottom and makes the interior fluid of oil storage tank can get into the pinion bearing reduction gear high-speed operation, the gear wheel has thrown lubricated pinion bearing with lubricating oil, lubricating oil also gets rid of the storage tank and saves simultaneously. When the speed reducer runs at low speed, lubricating oil in the oil storage tank can enter the pinion bearing for lubrication.
Description
Technical Field
The utility model relates to a reduction gear field especially relates to a reduction gear bearing lubricating structure.
Background
An electric drive bridge main reducer assembly adopting a parallel shaft mode in the new energy automobile industry is shown in figure 1 and comprises a reducer shell, a pinion and a bull gear, wherein the pinion and the bull gear are both installed on the reducer shell through gear shafts and meshed with the bull gear, and a pinion bearing is arranged between the gear shaft of the pinion and the reducer shell.
The pinion bearing of the electric drive bridge main reducer assembly is lubricated by gear lubricating oil thrown up by the rotation of the bull gear. When the speed reducer runs at a low speed, the condition that the large gear cannot throw lubricating oil to the pinion bearing is easy to occur, so that the pinion bearing is not lubricated enough, and ablation is caused.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: the bearing lubricating structure of the speed reducer has a good lubricating effect.
The technical scheme adopted for solving the problems is as follows: reduction gear bearing lubricating structure includes retarder housing, pinion and gear wheel all install on retarder housing through the gear shaft, pinion and gear wheel meshing, be provided with pinion bearing between the gear shaft of pinion and the retarder housing, still include the oil blocking piece, the oil blocking piece is located between pinion and the gear wheel and is connected with retarder housing, the last oil storage tank that has of oil blocking piece, the top of oil storage tank is higher than pinion bearing bottom and makes the interior fluid of oil storage tank can get into pinion bearing.
Further, the method comprises the following steps: the sliding structure comprises a connecting bolt and a sealing ring, a mounting hole is formed in the shell of the speed reducer, the connecting bolt penetrates through the mounting hole and is connected with the oil blocking block, and the connecting bolt and the mounting hole are sealed through the sealing ring.
Further, the method comprises the following steps: the sealing ring is arranged on the connecting bolt.
Further, the method comprises the following steps: the surface of the oil blocking block facing the bull gear is arranged along the tangential direction of the bull gear.
The utility model has the advantages that: when the speed reducer operates at a high speed, the large gear throws lubricating oil to lubricate the pinion bearing, and meanwhile, the lubricating oil is thrown into the oil storage tank to be stored. When the reduction gear was low operation, lubricating oil can enter into pinion bearing and lubricate in the oil storage tank, consequently the utility model discloses a pinion bearing is lubricated effectual, can avoid pinion bearing ablation, increases the reduction gear life-span, reduces after-sale maintenance cost.
Drawings
FIG. 1 is a view of the bearing lubrication structure of the reducer;
FIG. 2 is an enlarged view of a portion of the bearing lubrication structure of the reducer;
labeled as: the reducer comprises a reducer shell 1, a mounting hole 11, a pinion 2, a gearwheel 3, a pinion bearing 4, an oil baffle block 5, a connecting bolt 6, an oil storage tank 7 and a sealing ring 8.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the following detailed description.
As shown in fig. 1 and 2: reduction gear bearing lubricating structure includes retarder housing 1, pinion 2 and gear wheel 3 all install on retarder housing 1 through the gear shaft, pinion 2 and gear wheel 3 mesh, be provided with pinion bearing 4 between pinion 2's the gear shaft and the retarder housing 1, still include oil blocking piece 5, oil blocking piece 5 is located between pinion 2 and the gear wheel 3 and is connected with retarder housing 1, oil storage tank 7 has on the oil blocking piece 5, the top of oil storage tank 7 is higher than 4 bottoms of pinion bearing and makes fluid in the oil storage tank 7 can get into pinion bearing 4.
When the speed reducer operates at a high speed, the large gear 3 throws lubricating oil to lubricate the pinion bearing 4, and meanwhile, the lubricating oil is thrown into the oil storage tank 7 to be stored. When the speed reducer operates at a low speed, lubricating oil in the oil storage tank 7 can enter the pinion bearing 4 for lubrication.
The oil deflector 5 can be connected to the gear housing 1 in various ways, for example, by being integrally formed with the gear housing 1. The utility model discloses preferred mode as follows: the reducer bearing lubricating structure comprises a connecting bolt 6 and a sealing ring 8, a mounting hole 11 is formed in the reducer shell 1, the connecting bolt 6 penetrates through the mounting hole 11 and is connected with the oil blocking block 5, and the connecting bolt 6 and the mounting hole 11 are sealed through the sealing ring 8. This mode both fixes the oil deflector 5 and prevents the lubricating oil from leaking out of the mounting hole 11.
The sealing ring 8 can be arranged on the reducer shell 1 or on the connecting bolt 6, and is more convenient to be arranged on the connecting bolt 6.
The surface of the oil baffle block 5 facing the gearwheel 3 is preferably arranged tangentially to the gearwheel. So can reduce the piece of keeping off oil 5 and get rid of the blockking of fluid to gear wheel 3, the lubricating oil of being convenient for gets into oil storage tank 7.
