Problems solved by technology
However, after the lubricating oil is thrown by the oil throwing plate to the top cover of the gearbox, part of the lubricating oil is bounced back to the oil pool of the gearbox by the top cover of the gearbox, thereby reducing the amount of lubricating oil entering the oil collection pool. Insufficient amount may lead to failure of rolling bearings due to insufficient lubrication

Embodiment Construction
[0028] The technical solution of the present invention will be further described below in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for ease of description, the drawings only show parts related to the present invention, but not all.
[0029] In the description of the present invention, it should be noted that the terms "installation", "connected" and "connected" should be understood in a broad sense, unless otherwise clearly specified and limited. For example, they can be fixed or detachable. Connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the internal communication between two components. For those of ordinary skill in the art, the specific meaning of the abov...

The invention relates to the technical field of gear boxes, in particular to an oil guide structure for a gear box and the gear box. The oil guide structure for the gear box comprises a box body, a top penetrating cover, an oil inlet hole and a first oil guide hood. The box is provided with an oil pool. The top penetrating cover is arranged on the box in a sealed covering manner, and an oil collection cavity is defined by the top penetrating cover and the box. The oil inlet hole is formed in the upper end of the box and communicates with the oil pool and the oil collection cavity. The interiorof the first oil guide hood is hollow, a first opening is formed in the lower end, a second opening is formed in the upper end, the first oil guide hood is arranged outside the box and is located atthe oil inlet hole, the first opening communicates with the oil inlet hole, the second opening communicates with the oil collection cavity, the outer surface of the first oil guide hood is in a frustum shape, and the cross sectional areas are gradually reduced from bottom to top. By means of the oil guide structure and the gear box, the quantity of lubricating oil rebounded back to the oil pool ofthe gear box by the top penetrating cover of the gear box can be reduced, and therefore the quantity of lubricating oil entering the oil collection pool is increased, and rolling bearings are fully lubricated.
Description
Technical field [0001] The invention relates to the technical field of gearboxes, in particular to an oil guiding structure for gearboxes and gearboxes. Background technique [0002] Most of the gears and shafts in the vertical gearbox are installed perpendicular to the ground. According to the conventional oil-immersion lubrication method, the power consumption of the gearbox will increase, the temperature will rise, and the oil volume will increase. As a result, gears and bearings cannot all be lubricated by immersion in oil. Using splash lubrication, the oil is thrown into the oil collecting pool on the upper part of the gear box, and the lubricating oil flows to the rolling bearing through the lubrication hole for lubrication. But after the lubricating oil is thrown to the top of the gear box through the cover, part of the lubricating oil is rebounded back to the oil sump of the gear box by the top of the gear box, thus reducing the amount of lubricating oil entering the oil...
