Problems solved by technology
Of course, it can also be solved by increasing the forced lubrication of the oil pump, but adding the oil pump will not only increase the production cost, but also increase the difficulty and complexity of the system layout, which deviates from the original intention of miniaturization

The invention relates to the technical field of speed reducers and discloses a lubrication structure for a bearing of a speed reducer. The structure comprises the bearing arranged in a speed reducer shell, a bearing baffle and a speed reducer shaft; a bearing inner ring is installed on the speed reducer shaft, one side of the bearing is provided with the bearing baffle, the bearing baffle is fixedon the speed reducer shell, and the speed reducer shell is used as a bearing base at the same time; the bearing baffle comprises baffle stop shoulders abutting against the bearing, and the sides, away from the bearing, of the baffle stop shoulders extend in the axial direction of the speed reducer shaft and retract inwards in the radial direction of the speed reducer shaft to form lip baffles; the bearing baffle, the speed reducer shell and the bearing base cooperate to form a bearing oil containing cavity, and an oil guide groove is formed in the portion, opposite to the bearing oil containing cavity, of the speed reducer shell. According to the speed reducer bearing lubrication structure, a lubrication oil storage mechanism is assembled at the bearing to contain enough oil, the bearingcan be subjected to stable oil-bath lubrication during work, the lubrication effect is improved, and the miniaturization design of the speed reducer is facilitated.
Description
technical field [0001] The invention relates to a technology in the field of reducers, in particular to a bearing lubrication structure of a reducer. Background technique [0002] The inner bearings of the reducer are all open bearings. In the conventional design, an oil guide groove is provided on the reducer housing, and the oil guide groove guides the lubricating oil introduced by the gear of the reducer to the bearing to lubricate the bearing. [0003] At present, the development of new energy vehicles in the market has put forward miniaturization requirements for the reducer, resulting in a very compact structure of the components in the reducer (such as figure 1 As shown), the assembly position of the bearing is often difficult to meet the optimal design, and the amount of lubricating oil introduced by the oil guide groove is insufficient, resulting in poor lubrication of the bearing. [0004] The above problems can be solved by improving the bearing performance, but...
