Description

Technical Field

[0001] This utility model relates to the field of speed reducer technology, and in particular to a speed reducer anti-oil leakage structure. Background Technology

[0002] As a power transmission component, speed reducers are widely used in various fields of industrial production. However, oil leakage is a common and pressing problem during the actual operation of speed reducers. Existing speed reducers have relatively simple venting structures. Typically, during high-speed operation of the gears inside the speed reducer, the oil temperature inside the gearbox rises, causing the oil to expand and generate a large amount of oil vapor. Since the existing vent cap is directly connected to the gearbox, when the pressure inside the gearbox increases due to the rising oil temperature, the oil vapor is directly discharged through the vent cap, easily causing oil leakage. Oil leakage not only wastes lubricating oil and increases equipment operating costs, but the overflowing oil also pollutes the surrounding environment, increases safety hazards, affects normal operation by workers, and can even cause accidents such as slips and falls. In addition, oil leakage can also negatively affect the performance and service life of the reducer. On the one hand, excessive consumption of lubricating oil will lead to insufficient lubrication between internal components of the reducer, thereby aggravating the wear of components, reducing transmission efficiency, and increasing the probability of equipment failure. On the other hand, oil leakage may also seep into the sealing components of the reducer, causing the seals to age and fail prematurely, further aggravating the oil leakage problem and forming a vicious cycle. Utility Model Content

[0003] In view of this, in order to solve the above problems, the purpose of this utility model is to provide a reducer oil leakage prevention structure, including a gearbox and a vent cap, and further including an expansion box, the expansion box being disposed between the gearbox and the vent cap, the expansion box having layered baffles inside, and adjacent baffles being symmetrically arranged.

[0004] In another preferred embodiment, the baffle has at least two layers.

[0005] In another preferred embodiment, the baffle is fixedly connected to the inner wall of the expansion tank.

[0006] In another preferred embodiment, the two ends of the expansion tank are respectively sealed and connected to the oil outlet of the gearbox and the oil inlet of the vent cap.

[0007] In another preferred embodiment, the baffles are spaced apart along the height direction of the expansion tank.

By setting an expansion box, it can effectively buffer the pressure impact brought by hot airflow. By setting multiple baffles, it can separate lubricating oil from hot airflow, thereby helping to reduce the occurrence of oil leakage and avoid a series of problems caused by oil leakage, such as lubricating oil loss, environmental pollution, and component wear.

[0013] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0014] In the description of this utility model, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "front", "back", "horizontal", and "vertical" are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0015] It should be noted that the terms "horizontal" and "vertical" in this utility model are used to describe approximate positional relationships, and not strictly "horizontal plane" or "vertical plane".

[0016] like Figure 1 As shown, a preferred embodiment of a speed reducer oil leakage prevention structure is provided, including a gearbox and a vent cap, and further including: an expansion box 1, which is disposed between the gearbox and the vent cap, and the expansion box 1 is provided with layered baffles 2 inside, with adjacent baffles 2 arranged symmetrically.

[0017] Furthermore, as a preferred embodiment, the baffle 2 has at least two layers.

[0018] Furthermore, as a preferred embodiment, the baffle 2 is fixedly connected to the inner wall of the expansion tank 1. Furthermore, the fixed connection can be achieved through welding, bolting, or snap-fitting, depending on the actual situation, to ensure that the baffle 2 will not loosen or fall off under the impact of oil and gas.

[0019] Furthermore, as a preferred embodiment, the horizontal length of the baffle 2 is greater than half the horizontal length of the expansion tank 1, and the projections of two adjacent baffles 2 in the vertical direction partially overlap to increase the contact time and opportunity between the hot airflow and the surface of the baffle 2. This prevents the hot airflow from rising directly in a straight line, but forces it to change its flow direction, thereby avoiding the situation where the hot airflow carrying lubricating oil rises directly in a straight line through the expansion tank 1 from the gap between the two adjacent baffles 2 without being effectively separated. This helps to ensure the continuity and efficiency of oil-gas separation.

[0020] Furthermore, as a preferred embodiment, the two ends of the expansion tank 1 are respectively sealed and connected to the oil outlet of the gearbox and the oil inlet of the vent cap.

[0021] Furthermore, as a preferred embodiment, the baffles 2 are spaced apart along the height direction of the expansion tank 1.

[0022] Furthermore, as a preferred embodiment, the expansion box 1 has a hollow cavity structure.

[0023] The working principle of this utility model is as follows: When the reducer is running, the oil temperature inside the gearbox will rise due to the high-speed rotation of the gears, causing the oil to expand and generate a large amount of hot air and splashing lubricating oil. Under the pressure inside the gearbox, the hot air carrying lubricating oil enters the expansion tank 1 through the oil outlet of the gearbox. The expansion tank 1 can first buffer the pressure impact brought by the hot air. Then, when the hot air hits the first baffle 2, the speed will decrease instantly and the flow direction will change. During this process, the lubricating oil in the hot air is more likely to adhere to the baffle 2 due to gravity and friction with the surface of the baffle 2. Over time, the lubricating oil adhering to the baffle 2 will continuously gather and form larger oil droplets, which will eventually slide down the surface of the baffle 2 and return to the inside of the gearbox. The hot air separated by the first baffle 2 continues to flow upward. When the hot air flows to the second baffle 2, the above oil-gas separation process is repeated again. In this way, through the blocking and separation effect of multiple baffles 2, most of the lubricating oil is separated out, which greatly reduces the oil content in the gas entering the vent cap.

[0024] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
