Description
Technical Field
[0001] This utility model relates to the technical field of speed reducer accessories in the chemical industry, and in particular to an oil separator for an inverted speed reducer motor. Background Technology
[0002] In the chemical industry, motors and speed reducers are a common combination used in mixing and other equipment. The conventional setup is with the motor above the speed reducer. However, in practice, different connection methods exist. Due to process requirements or space constraints, sometimes the motor is installed below the speed reducer, i.e., an inverted speed reducer motor.
[0003] Inverting the installation positions of the reducer and motor will cause the oil in the reducer to flow downwards into the motor during use, affecting the normal operation of the motor. Even with a single oil seal, oil leakage will usually occur after a long period of use. If the oil leakage is not detected and drained in time, it will pose a significant safety hazard. Utility Model Content
[0004] To address the aforementioned technical problems, this utility model provides an oil separator for an inverted gearbox motor. This oil separator is installed between the inverted gearbox and the motor. In practical applications, this oil separator can promptly detect oil leakage due to aging of the shaft seal after long-term operation of the inverted gearbox, and drain the lubricating oil immediately. This prevents lubricating oil from flowing along the motor shaft into the motor, reducing the frequency of motor maintenance and mitigating potential safety hazards caused by oil ingress into the motor.
[0005] To achieve this technical objective, the present invention adopts the following solution: An inverted reducer motor oil separator includes an oil separator disposed between an inverted reducer and a motor. The reducer and motor are connected by a coupling. The oil separator includes an oil separator body, a reducer connecting plate, a motor connecting plate, and a fastening device. The reducer connecting plate is disposed above the oil separator body and connected to the reducer, and the motor connecting plate is disposed below the oil separator body and connected to the motor.

In practical applications, this oil separator can promptly detect oil leakage due to aging of the shaft seal after long-term operation of the inverted reducer, and promptly discharge the leaked lubricating oil to prevent lubricating oil from flowing into the motor along the motor shaft. This reduces the frequency of motor maintenance and lowers the safety hazards that may be caused by oil ingress into the motor.

Detailed Implementation
[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.
[0023] Please see Figures 1 to 5 This utility model provides an oil separator for an inverted speed reducer motor, including an oil separator 1. The oil separator 1 is disposed between an inverted speed reducer 2 and a motor 3, which are connected by a coupling 4. The oil separator 1 mainly includes an oil separator body 11, a speed reducer connecting plate 12, a motor connecting plate 13, and a fastening device 14. The oil separator body 11 is used to prevent lubricating oil from the speed reducer 2 from leaking into the motor 3. The speed reducer connecting plate 12 is disposed above the oil separator body 11 and connected to the speed reducer 2. The motor connecting plate 13 is disposed below the oil separator body 11 and connected to the motor 3. The speed reducer 2, the oil separator 1, and the motor 3 are positioned together by the speed reducer connecting plate 12 and the motor connecting plate 13. The fastening device 14 is used to fix the oil separator 1 to the speed reducer 2 and the motor 3. Example 1
[0024] Please see Figures 1 to 3 The top of the oil separator body 11 is provided with an oil receiving plate 111 for receiving lubricating oil leaking from the reducer 2; the oil receiving plate 111 is provided with an oil drain hole 112, and the oil separator body 11 is provided with an oil guide groove 115. One end of the oil guide groove 115 is connected to the oil drain hole 112, and the other end of the oil guide groove 115 passes through the oil separator body 11 for discharging the lubricating oil in the oil receiving plate 111 into the oil separator device 1.
[0025] The oil receiving tray 111 has a central hole 116 in the center, and a contact platform 114 is provided on the upper surface of the oil receiving tray 111. The contact platform 114 is located outside the central hole 116, and the central hole 116 is perpendicular to the contact platform 114 to ensure that the motor output shaft 31 can pass through smoothly.
[0026] The coupling 4 is positioned above the oil separator body 11 and is used to connect the motor output shaft 31 and the reducer input shaft 21. The coupling 4 includes an upper end 41 connected to the reducer input shaft 21 and a lower end 42 connected to the motor output shaft 31. The upper end 41 has a reducer shaft hole 43 matching the diameter of the reducer input shaft 21, and the lower end 42 has a motor shaft hole 44 matching the diameter of the motor output shaft 31. The motor output shaft 31 passes through the central hole 116 and connects to the motor shaft hole 44. This connection method ensures the connection and positioning between the motor output shaft 31 and the reducer input shaft 21, thereby transmitting the torque of the motor 3 to the reducer 2.
[0027] Specifically, the diameter of the center hole 116 is larger than the diameter of the motor output shaft 31, so that the motor output shaft 31 can pass through smoothly.
[0028] The outer diameter of the lower end 42 of the coupling is larger than the diameter of the contact platform 114. The lower end 42 of the coupling is in contact with the contact platform 114. When the reducer 2 experiences oil leakage due to shaft seal aging after long-term operation, the lubricating oil flowing out of the reducer 2 flows downward along the coupling 4. Because the outer diameter of the lower end 42 of the coupling is larger than the diameter of the contact platform 114, the lubricating oil will flow through the contact platform 114 into the oil receiving pan 111, and then be discharged from the oil separator 1 along the oil drain hole 112 and the oil guide groove 115. It will not flow through the center hole 116 onto the motor output shaft 31, and then flow into the motor 3, causing damage to the motor 3.
[0029] The fastening device 14 consists of four bolt holes 141 evenly distributed around the oil separator body 11. The motor 3 and the reducer 2 are fixedly connected by the fastening device 4 to prevent the oil separator 1 from moving and causing the lubricating oil to be unable to be isolated. Example 2
[0030] Please see Figure 4 The oil separator body 11 has a central hole 116 in the middle and an oil storage chamber 117 inside for storing lubricating oil leaking from the reducer 2. The central hole 116 and the oil storage chamber 117 are connected. An observation device 113 is provided on the side wall of the oil separator body 11. The observation device 113 can clearly and quickly determine whether the reducer 2 is leaking oil and take timely action.
[0031] Furthermore, the observation device 113 is detachably connected to the oil separator body 11.
[0032] Please see Figure 5 The coupling 4 is a stepped cylinder used for direct connection between the reducer 2 and the motor 3. The coupling 4 includes a lower end 42 and a connecting shaft 45. The connecting shaft 45 replaces the original motor output shaft 31 and is connected to the reducer 2. The lower end 42 of the coupling has a motor shaft hole 44 that matches the diameter of the motor output shaft 31. The diameter of the coupling 4 is smaller than the diameter of the central hole 116. The coupling 4 passes through the central hole 116 and is connected to the motor output shaft 31 through the motor shaft hole 44.
[0033] Furthermore, the outer diameter of the lower end 42 of the coupling is larger than the diameter of the motor output shaft hole 32 on the motor housing 3. When the reducer 2 experiences oil leakage due to shaft seal aging after long-term operation, the lubricating oil flowing out of the reducer 2 flows downward along the coupling 4 into the oil storage chamber 117. Because the outer diameter of the lower end 42 of the coupling is larger than the diameter of the motor output shaft hole 32, the lubricating oil will not flow directly onto the motor output shaft 31, thus preventing the lubricating oil from flowing into the motor 3. The observation device 113 can be opened immediately after the oil leakage is detected to handle the situation.
[0034] Through the above embodiments, this utility model, without changing the original installation structure, adds an oil separator between the reducer and the motor to isolate oil leakage from the reducer, reduce the frequency of motor damage and maintenance, reduce safety hazards caused by motor failure, and reduce maintenance costs.
[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. If these modifications and variations fall within the scope of the claims of this utility model and their equivalents, they should be considered to be within the protection scope of this utility model.
