Description

Technical Field

[0001] This utility model relates to the field of active lubrication technology for speed reducers, and specifically to a lubrication system for a new energy speed reducer. Background Technology

[0002] The reducer includes a reducer housing and transmission components such as gears and bearings disposed inside the reducer housing. The reducer housing includes a main housing and a reducer housing, which are connected by bolts. After the bolt connection, an internal cavity is formed, in which the transmission components such as gears and bearings are disposed.

[0003] Existing gearbox lubrication systems typically include an oil pan (usually the lowest part of the internal cavity of the gearbox housing, used to store lubricating oil), oil pipes, an oil filter, an oil pump, and an oil cooler. During operation, the oil pump draws oil from the oil pan into the suction port, then through the oil filter, oil pump, oil pipes, oil cooler, and oil passages on the gearbox housing, delivering the oil to various parts requiring lubrication, and finally returning it to the oil pan. However, the oil filter in existing gearbox lubrication systems is installed inside the cavity via bolts or threads, requiring a large internal cavity design, resulting in high lubricating oil consumption, numerous auxiliary parts in the lubrication circuit, complex installation and disassembly, high cost, and susceptibility to failure. Utility Model Content

[0004] In order to solve the technical problems existing in the background technology, this utility model proposes a lubrication system for a new energy reducer.

[0005] This utility model proposes a lubrication system for a new energy reducer, comprising: an oil pan, an oil pump, and an oil filter, wherein:

[0006] The reducer housing has an oil pump chamber and an oil filter chamber, which are coaxial and connected. The lowest part of the side wall of the oil filter chamber has an oil suction port with an opening facing downward and connected to the oil pan.

[0007] The oil pump is installed inside the oil pump chamber, and the oil pump fixes the oil filter inside the oil filter chamber by axial limiting.

[0008] Preferably, the oil suction port is coaxial with the oil drain port located at the lowest position at the bottom of the oil pan.

[0009] Preferably, it also includes an oil return channel connected to the oil pan, the oil return channel being funnel-shaped, with the larger end connected to the oil pan.

[0010] Preferably, it also includes an oil cooler and an oil pumping passage connecting the oil cooler and the oil pump chamber; the oil pumping passage is machined or cast onto the outer wall of the reducer housing.

[0011] Preferably, it also includes an oil passage disposed on the reducer housing.

[0012] Preferably, the reducer housing includes a main housing and a reducer housing connected by bolts and forming a cavity at their junction; the oil passage includes an oil passage section one disposed on the main housing and an oil passage section two disposed on the reducer housing, the oil passage section one and the oil passage section two are connected and conductive, and the mating surface of the two is coplanar with the joint surface of the main housing and the reducer housing.

[0013] Preferably, an oil pan is formed at the lowest part of the cavity.

[0014] Preferably, both the oil pump chamber and the oil filter chamber are located on the main housing.

[0015] This invention features an oil pump chamber and an oil filter chamber, arranged coaxially. The oil filter is fixed within the oil filter chamber by axial positioning after the oil pump is assembled, eliminating the need for bolts or threads. Compared to traditional methods of fixing the oil filter with bolts or threads, this design significantly simplifies the internal cavity structure of the reducer, allowing for a smaller internal cavity volume and reduced oil filling volume. Furthermore, the oil suction port is cleverly positioned at the lowest point of the oil filter chamber sidewall, with its plane pointing downwards, further reducing the suction port height and oil filling volume. Additionally, the oil filter chamber design eliminates the need for an additional housing structure, simplifying both the oil filter and suction port structure. Therefore, compared to traditional lubrication systems, this invention can meet the lubrication requirements of products with extremely low oil volumes, while greatly simplifying processing, assembly, and disassembly, eliminating unnecessary auxiliary parts, and offering significant cost and efficiency advantages.

[0022] Reference Figure 1-3 This utility model proposes a lubrication system for a new energy reducer, comprising: an oil pump chamber 4 and an oil filter chamber 3 disposed on the reducer housing, an oil pan, an oil pump 12, and an oil filter 13, wherein:

[0023] The oil pump chamber 4 and the oil filter chamber 3 are coaxial and connected; the lowest part of the side wall of the oil filter chamber 3 is provided with an oil suction port 2 with an opening facing downward and connected to the oil pan. The oil pump 12 is installed in the oil pump chamber 4, and the oil filter 13 is fixed in the oil filter chamber 3 by axial limiting.

[0024] Compared to the traditional method of fixing the oil filter 13 with bolts or threads, this design greatly simplifies the structure of the internal cavity 14 of the reducer, allowing for a smaller volume design of the internal cavity 14 to reduce the amount of oil needed. Furthermore, the downward-facing design of the oil suction port 2 reduces its height, further decreasing the amount of oil needed.

[0025] In a further implementation, the oil suction port 2 is coaxial with the oil drain port 1 located at the lowest position at the bottom of the oil pan. This structural design facilitates machining, as the coaxial hole can be machined in one step by drilling or boring, reducing machining difficulty and time. On the other hand, it reduces additional oil passage branches or hole positions, thus reducing the complexity of the overall structure.

[0026] Reference Figure 4 The present invention proposes a lubrication system for a new energy reducer, which further includes an oil return channel 11 connected to the oil pan. The oil return channel 11 is funnel-shaped, and the larger end of the oil return channel 11 is connected to the oil pan. Compared with the traditional flat oil return channel 11, the funnel-shaped oil return channel 11 has a large angle, which greatly improves the oil return efficiency.

[0027] The present invention proposes a new energy reducer lubrication system, which also includes an oil cooler 7 and an oil pumping channel 6 connecting the oil cooler 7 and the oil pump chamber 4; the oil pumping channel 6 is attached to the outer wall of the reducer housing and is formed by machining or casting, without the need for an independent oil pipe. This design can greatly simplify the oil passage structure and further reduce the amount of oil added.

[0028] Reference Figure 5-6 The present invention proposes a new energy reducer lubrication system, which also includes an oil passage provided on the reducer housing; the reducer housing includes a main housing 5 and a reducer housing 8; the main housing 5 has a main housing 5 cavity, the reducer housing 8 has a reducer housing 8 cavity, the main housing 5 and the reducer housing 8 are connected by bolts, and the main housing 5 cavity and the reducer housing 8 cavity are connected and communicated to form a cavity 14 between them; the lowest part of the cavity 14 forms an oil pan (also called an oil pan cavity); the oil pump cavity 4 and the oil filter cavity 3 are both provided on the main housing 5.

[0029] The oil passage includes an oil passage section 9 on the main housing 5 and an oil passage section 10 on the reducing housing 8, which connects to and is conductive to the oil passage section 9. The mating surfaces of the oil passage sections 9 and 10 are coplanar with the mating surfaces of the main housing 5 and the reducing housing 8. Specifically, the end hole at one end of the oil passage section 9 is located on the end face of the main housing 5, and the end hole at one end of the oil passage section 10 is located on the end face of the reducing housing 8. When the main housing 5 and the reducing housing 8 are connected, the end hole of the oil passage section 9 on the end face of the main housing 5 connects to and is conductive to the end hole of the oil passage section 10 on the end face of the reducing housing 8. This structural design reduces processing difficulty and time, and eliminates the need for sealing at the mating surfaces of the oil passage sections 9 and 10.

[0030] As can be seen from the above, this utility model sets up an oil pump chamber 4 and an oil filter chamber 3, and arranges the oil pump chamber 4 and the oil filter chamber 3 coaxially. The oil filter 13 is fixed in the oil filter chamber 3 by the axial limiting of the oil pump 12 after assembly, without the need for bolts or threads. Compared with the traditional method of fixing the oil filter 13 with bolts or threads, the design of this utility model can greatly simplify the structure of the internal cavity 14 of the reducer, so that the volume of the internal cavity 14 of the reducer can be miniaturized to reduce the amount of oil added. At the same time, the oil suction port 2 is cleverly designed at the lowest position of the side wall of the oil filter chamber 3, and the plane of the oil suction port 2 is downward, reducing the height of the oil suction port 2, which can further reduce the amount of oil added. In addition, the design of the oil filter chamber 3 eliminates the need for an additional shell structure for the oil filter 13, simplifying the structure of the oil filter 13 and the oil suction port 2. Therefore, compared with traditional lubrication systems, this invention can meet the lubrication needs of products with extremely low oil levels, while greatly simplifying processing, assembly, and disassembly, eliminating unnecessary auxiliary parts, and having significant cost and efficiency advantages. In addition, the funnel-shaped design of the oil return channel 11 improves the oil return efficiency, and this solution can be applied to the design of oil-cooling solutions, making it widely applicable.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
