Technical Field

[0001] The utility model belongs to the technical field of reducers, in particular to a vertical reducer with a drainage cooling function. Background Art

[0002] Vertical reducers are a type of transmission device widely used in various fields. They match the speed and transmit torque between the prime mover and the working machine or actuator. Due to the complex working environment, vertical reducers are often used in situations where there is a lot of water vapor or even water pouring from above. Since the output shaft of the vertical reducer is generally located above the shell, it is easy for water to enter the output shaft, causing damage to the reducer due to water ingress. The traditional waterproofing method for vertical reducers is to set an oil seal at the output shaft. However, the oil seal is difficult to prevent the infiltration of water, and the reducer is still subject to damage due to water ingress.

[0003] A Chinese patent with application number 202220330692.6 discloses a vertical reducer with a drainage cooling function. By setting a water-spraying tray, water droplets dripping from the top of the output shaft are thrown out to prevent the water droplets from falling into the reducer and causing damage. At the same time, a collecting mechanism is set to collect the water droplets thrown out by the water-spraying tray, thereby achieving a cooling effect on the reducer to a certain extent. However, the vertical reducer with a drainage cooling function has the following shortcomings: there is a lot of water vapor at the input shaft position, and water vapor infiltration still cannot be avoided.

[0004] Therefore, in order to solve the above problems, a vertical reducer with drainage cooling function is proposed. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] The water removal assembly 11 includes a bracket 111, on which are respectively provided a water-absorbing roller 112 and a squeezing roller 113 which are arranged correspondingly up and down. The water-absorbing roller 112 is close to the output shaft 3, and the squeezing roller 113 is close to the water-absorbing roller 112. The water-absorbing roller 112 is composed of a central axis rod 1121 and a water-absorbing cotton sleeve 1122, and the water-absorbing cotton sleeve 1122 is sleeved on the central axis rod 1121.

[0033] Specifically, a primary oil seal 13 and a secondary oil seal 14 are respectively installed between the sealing seat 4 and the input shaft 2 , and the drying chamber 5 is located between the primary oil seal 13 and the secondary oil seal 14 .

[0034] Furthermore, a fixing ring 15 is fixedly connected to the top of the sealing seat 4, and a sealing ring 16 is provided on the inner wall of the fixing ring 15, and the sealing ring 16 performs a preliminary waterproof seal.

[0035] Furthermore, the sealing seat 4 is provided with an air inlet connector 17 and a one-way air outlet 18, both of which are connected to the drying chamber 5. The air inlet connector 17 is connected to the airflow duct 6, and the one-way air outlet 18 is used to discharge air carrying water vapor and prevent the entry of outside air.

[0036] It is worth noting that a water-absorbing cotton layer 19 is provided in the drying chamber 5, and the air inlet joint 17 and the one-way air outlet 18 are provided below the water-absorbing cotton layer 19. The water-absorbing cotton layer 19 can absorb part of the leaked water droplets and prevent the water droplets from flowing downward.

[0037] It is worth noting that the inlet position of the air cooler 7 is connected to an adsorption component 20, and an air inlet 21 is provided at one end of the adsorption component 20 away from the air cooler 7. The adsorption component 20 can adsorb water vapor and impurities in the air introduced into the drying chamber 5 to prevent water vapor from existing in the drying chamber 5.

[0038] It is worth mentioning that the adsorption component 20 includes a fixed sleeve 201, and partitions 202 are provided near both ends of the fixed sleeve 201. Absorbent cotton 203 and adsorption filler 204 are provided between the partitions 202, and the adsorption filler 204 can be set as activated carbon.

[0039] Among them, the air cooler 7 is the existing technology and will not be described in detail; at the same time, the utility model also includes a power supply, a controller and a switch, which are not the main technical points of this patent and will not be described in detail.

[0040] Working principle and process: When water falls on the vertical reducer, most of the water will fall on the water collecting tray 8, and then flow to the position of the water guide pipe 9, and finally fall into the cooling groove arranged on the shell 1. Part of the water will leak downward along the input shaft 2. At this time, the primary oil seal 13 can isolate most of the water, and part of the water vapor will leak downward. After entering the drying chamber 5 in the sealing seat 4, due to the large space of the drying chamber 5, the water vapor will diffuse in the drying chamber 5 to reduce the downward leakage of water vapor. The air cooler 7 is started regularly, and the outside air enters the adsorption component 20 through the air inlet 21. The partition net 202, absorbent cotton 203, adsorption filler 204, etc. in the fixed sleeve 201 can absorb water vapor and dust in the air. After passing through the air cooler 7, the air becomes wind flow, and the wind flow is introduced into the drying chamber 5 after passing through the wind flow duct 6, so that the liquid water in the drying chamber 5 is quickly dried and discharged from the one-way air outlet 18 along with the wind flow. Part of the water vapor will be discharged from the one-way air outlet 18. The wind will flow upward along the input shaft 2 to dry the remaining moisture. The air in the drying chamber 5 is dry, which can reduce the infiltration of moisture. The absorbent cotton layer 19 arranged in the drying chamber 5 can absorb some of the fallen water droplets. After the wind flow is introduced, the absorbent cotton layer 19 is dried by the wind flow, so as to facilitate the use of the absorbent cotton layer 19, which greatly enhances the sealing effect of the input shaft 2 of the vertical reducer. At the same time, a dewatering component 11 is arranged at the output shaft 3. When the output shaft 3 rotates, the absorbent roller 112 will be driven to rotate. The absorbent cotton sleeve 1122 of the absorbent roller 112 can absorb moisture on the outer surface of the output shaft 3. When the absorbent roller 112 rotates, the squeezing roller 113 will be driven to rotate. The squeezing roller 113 will squeeze the absorbent cotton sleeve 1122 of the absorbent roller 112 to squeeze out the absorbed water, so that the absorbent cotton sleeve 1122 can continue to absorb water, thereby preventing moisture from accumulating at the output shaft 3 and preventing water from entering and damaging the vertical reducer.
