Description

Technical Field

[0001] This utility model relates to the field of speed reducer technology, specifically a speed reducer with temperature monitoring. Background Technology

[0002] Speed ​​reducers play a crucial role in matching speeds and transmitting torque between prime movers and driven machines or actuators, and are widely used in modern machinery. Speed ​​reducers can be broadly classified into two categories based on their application: general-purpose speed reducers and special-purpose speed reducers. The design, manufacturing, and usage characteristics of these two types differ significantly.

[0003] Application number CN202420844541.1 discloses a speed reducer with temperature monitoring, relating to the technical field of speed reducers. It solves the problem that when water-cooling lubricating oil with temperature, the oil's temperature is transferred to the water, and prolonged use causes the water temperature to gradually rise, resulting in poor subsequent water cooling effect on the lubricating oil. Furthermore, because the filter is located inside the speed reducer, long-term use can easily cause blockage of the filter, and it is not easy to disassemble and clean the filter. The device includes a speed reducer, an oil pump, and a blower. A temperature sensor is fixedly installed on the front side wall of the speed reducer, with the sensing part of the sensor penetrating through the side wall to the interior of the machine body. The oil pump is fixedly installed on the top surface of the speed reducer. Through the cooperation of the oil inlet pipe, spray head, and blower, the circulating lubricating oil can be easily cooled by blowing cold air, reducing its temperature.

[0004] When this application is used, the lubricating oil is gathered into a stream and flows into the oil inlet hopper. In this static air cooling method, the cold air cannot effectively penetrate the central area of ​​the lubricating oil, resulting in limited heat dissipation and low cooling efficiency. Utility Model Content

[0005] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0006] Therefore, the technical solution adopted by this utility model is as follows: A speed reducer with temperature monitoring includes a flow splitting structure and a cooling mechanism. The flow splitting structure includes a speed reducer body, an oil extraction pipe installed on one side of the speed reducer body, a circulation pump connected to the outer end of the oil extraction pipe, a flow splitting box connected to the output end of the circulation pump, a manifold box disposed on one side of the flow splitting box, multiple spiral pipes connected between the flow splitting box and the manifold box, and an oil return pipe connected between the speed reducer body and the manifold box. The cooling mechanism includes an air duct disposed between the multiple spiral pipes and connected to the manifold box, and multiple distributed channels connected and communicating with the air duct.

[0007] By adopting the above technical solution, the lubricating oil drawn in through the oil extraction pipe enters the distribution box and is divided into multiple streams by the spiral tube. The shape of the spiral tube increases the path of the lubricating oil. Then, cold air is introduced into the air duct, and the cold air is distributed through multiple dispersed channels to specifically cool each spiral tube, thereby achieving the purpose of heat exchange with the lubricating oil and improving the air cooling effect.

[0008] In a preferred embodiment, this invention can be further configured such that multiple spiral tubes are evenly spaced and arranged around the outside of the duct, and the sum of the flow velocities of the multiple spiral tubes is equal to the flow velocity of the oil extraction pipe.

[0009] In a preferred embodiment, the present invention can be further configured such that: multiple dispersive channels are located inside multiple spiral tubes, and the vertical cross-section of the dispersive channels is set as an isosceles trapezoid.

[0010] In a preferred embodiment, the present invention can be further configured such that a temperature sensor is inserted into the front side of the combiner box, and the temperature sensor is electrically connected to an external PLC.

[0011] In a preferred embodiment, the present invention can be further configured such that: a sleeve is installed on one side of the diversion box, the sleeve is concentrically arranged with the oil extraction pipe, and the air duct is inserted into the sleeve.

[0012] In a preferred embodiment, the present invention can be further configured such that: two clamps are sleeved on the outer side of the air duct, and both clamps are fixedly connected to the inner side of the manifold box.

[0013] In a preferred embodiment, the present invention can be further configured such that: a table frame is fixedly connected to the top of the reducer body, and the circulating pump, the distributor box, and the junction box are all fixedly connected to the top of the table frame.

[0014] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: 1. In this utility model, the lubricating oil drawn in by the oil extraction pipe enters the distribution box and is divided into multiple streams by the spiral tube. The shape of the spiral tube increases the path of the lubricating oil. Then, cold air is introduced into the air duct, and the cold air is distributed through multiple dispersed channels to cool each spiral tube in a targeted manner, thereby achieving the purpose of heat exchange with the lubricating oil and improving the air cooling effect.

[0015] 2. In this utility model, the reducer body and the circulating pump start synchronously. Then, the lubricating oil in the reducer body is sucked out by the oil extraction pipe, and then flows through the distributor box, spiral pipe, manifold box and return pipe in sequence, and then enters and returns to the reducer body. The lubricating oil is recycled, which improves the resource utilization rate. Attached Figure Description

The cooling mechanism 200 includes a duct 210 disposed between multiple spiral tubes 160 and connected to a manifold box 150, and multiple dispersed channels 220 connected to and communicating with the duct 210.

[0022] Furthermore, multiple spiral tubes 160 are evenly spaced and arranged around the outside of the air duct 210. The sum of the flow velocities of the multiple spiral tubes 160 is equal to the flow velocity of the oil extraction pipe 120. The layout design of the spiral tubes 160 can evenly receive the cold air flowing out from the air duct 210.

[0023] Furthermore, multiple distribution channels 220 are located inside multiple spiral tubes 160 respectively. The vertical cross-section of the distribution channel 220 is set as an isosceles trapezoid. The layout design of the distribution channel 220 can provide targeted air cooling for each spiral tube 160.

[0024] Furthermore, a table frame is fixedly connected to the top of the reducer body 110, and the circulating pump 130, the flow divider box 140, and the junction box 150 are all fixedly connected to the top of the table frame. The table frame can improve the overall structural stability of the device. Example

[0025] Combination Figure 1-4 As shown, based on Embodiment 1, a temperature sensor 300 is inserted into the front side of the junction box 150. The temperature sensor 300 is electrically connected to an external PLC. By setting the temperature sensor 300, the temperature of the lubricating oil in the junction box 150 after cooling can be monitored in real time, effectively preventing damage to the reducer body 110. Example

[0026] Combination Figure 3-4 As shown, in the above embodiment, a sleeve 400 is installed on one side of the diversion box 140. The sleeve 400 is concentrically arranged with the oil extraction pipe 120. The air duct 210 is inserted into the sleeve 400. The sleeve 400 can improve the stability of the oil extraction pipe 120.

[0027] Furthermore, two clamps 500 are fitted on the outer side of the air duct 210, and both clamps 500 are fixedly connected to the inner side of the junction box 150. The clamps 500 can improve the installation firmness of the air duct 210.

[0028] The working principle and usage process of this utility model are as follows: The reducer body 110 and the circulating pump 130 start synchronously. Then, the lubricating oil in the reducer body 110 is sucked out by the oil extraction pipe 120, and then flows through the distribution box 140, the spiral tube 160, the manifold box 150 and the return oil pipe 170 in sequence, and then enters and returns to the reducer body 110. During this period, cold air is introduced into the air duct 210, and then multiple dispersion channels 220 divide the cold air into multiple streams to specifically air-cool each spiral tube 160. The setting of the spiral tube 160 realizes the diversion of lubricating oil, increases the path of lubricating oil, and improves the air-cooling effect.
