Description

Technical Field

[0001] This utility model relates to a device for preventing grease overflow in open gear sets of mills, belonging to the field of mineral processing machinery technology. Background Technology

[0002] In the mineral processing industry, grinding mills are widely used due to their high efficiency and stable grinding performance. However, in actual operation, oil leakage on both sides of the pinion shaft of the grinding mill occurs frequently, becoming one of the main problems affecting the long-term stable operation of the equipment.

[0003] Currently, the industry commonly uses felt or sealing gaskets on both sides of the gear shaft to achieve sealing and reduce grease leakage. While this solution alleviates oil leakage to some extent, it still has significant drawbacks: felt and sealing gaskets are consumable parts, and their sealing performance deteriorates due to wear and aging during long-term operation, requiring frequent shutdowns for replacement. This not only increases equipment maintenance costs but also affects production continuity, placing a heavy burden on users for long-term operations. Therefore, improvements are urgently needed. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model designs a grease overflow prevention device for open gear sets in mills, which can effectively prevent oil from overflowing from both sides of the pinion shaft of the mill.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A device for preventing grease overflow in an open gear set of a mill includes a circular ring with multiple blades evenly spirally arranged on one side surface of the ring. The circular ring includes two base plates that are spliced ​​together and detachably connected by a connecting component.

[0007] Furthermore, the connecting assembly includes a fixing plate and fixing bolts; fixing plates are fixedly connected to both outer sides of the base plate, and two fixing plates at one end of the two base plates are connected through fixing bolts.

[0008] Furthermore, a sealing ring is fitted and fixed to the inner ring of the circular ring.

[0009] Furthermore, the fixing plate and the base plate are integrally formed.

[0010] Compared with the prior art, this utility model has the following features and beneficial effects:

[0011] This invention utilizes a ring-shaped structure and multiple blades. When the mill pinion shaft rotates, the spirally arranged blades generate directional airflow, creating centrifugal pressure. This airflow guides splashed grease towards the gear meshing area. Simultaneously, the ring-shaped structure prevents grease from overflowing axially, effectively avoiding oil leakage. Furthermore, the two base plates are connected by fixing bolts, allowing for separate splicing and fixing. This allows for direct installation on the mill pinion shaft without disassembling it, making it suitable for applications with limited space or where disassembly is inconvenient.

[0016] The present invention will now be described in more detail with reference to the embodiments.

[0017] Please see Figures 1 to 3 The grease overflow prevention device for the open gear set of the mill in this embodiment includes an annular body 100. Specifically, the annular body 100 is fixedly sleeved on the pinion shaft of the mill.

[0018] To avoid oil leakage from the mill pinion shaft, multiple blades 2 are evenly spirally arranged on one side surface of the annulus 100. With the arrangement of the blades 2, when the mill pinion shaft rotates, each spirally arranged blade 2 can generate directional airflow and form centrifugal wind pressure. The airflow guides the splashed grease to the gear meshing area. At the same time, the annulus 100 can also prevent grease from overflowing axially, thereby effectively preventing oil leakage.

[0019] The annular body 100 includes two interlocking base plates 3 that are detachably connected by a connecting component. The detachable base plates 3 facilitate installation and connection.

[0020] Furthermore, the connecting assembly includes a fixing plate 4 and a fixing bolt 1.

[0021] Among them, the outer sides of both ends of the base plate 3 are fixedly connected to the fixing pressure plate 4, and the two fixing pressure plates 4 at one end of the two base plates 3 are connected by fixing bolts 1.

[0022] The two base plates 3 are connected by fixing bolt 1, so that the two base plates 3 can be spliced ​​and fixed separately. They can be directly installed on the mill pinion shaft without disassembling the mill pinion shaft, which is suitable for working conditions where space is limited or disassembly is inconvenient.

[0023] Furthermore, a sealing ring is fitted and fixed to the inner ring of the annular body 100 to further prevent oil leakage.

[0024] Furthermore, the fixed pressure plate 4 and the base plate 3 are integrated, reducing the number of connection points and improving connection reliability.

[0025] The working principle of this utility model is as follows: When in use, two base plates 3 are fitted onto the pinion shaft of the mill, and then the two ends of the two base plates 3 are connected by fixing bolts 1 to ensure that the ring body 100 is tightly fitted onto the pinion shaft of the mill. When the pinion shaft of the mill rotates, the spirally arranged blades 2 can generate directional airflow and form centrifugal wind pressure. The airflow guides the splashed grease to the gear meshing area. At the same time, the ring body 100 can also prevent the grease from overflowing axially, thereby effectively avoiding oil leakage.

[0026] In the description of this utility model, it should be noted that the terms "inner", "outer", "upper", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.
