Description

Technical Field

[0001] The invention relates to the technical field of hydraulic drive motors, and in particular to a hydraulic high-efficiency drive motor that is convenient for heat dissipation. Background Art

[0002] The hydraulic high-efficiency drive motor is an advanced power device that integrates hydraulic and electric technologies. The motor drives the hydraulic pump to convert mechanical energy into hydraulic energy. After being precisely adjusted by the control valve, the high-pressure oil drives the hydraulic motor to rotate and output mechanical energy to drive the load. It has the advantages of large hydraulic torque, flexible speed regulation, stable and reliable motor, and precise control. It can be steplessly regulated and has good overload protection. It is widely used in heavy and complex working conditions such as mining, port hoisting, and industrial production.

[0003] Overheating of hydraulic high-efficiency drive motors can cause many hazards. First, it accelerates the aging of motor insulation and shortens its service life. In severe cases, the insulation fails and causes short-circuit faults. Overheating causes uneven thermal expansion of various components inside the motor, causing increased mechanical wear and reduced precision, resulting in abnormal operating noise and increased vibration. Excessive temperature will also reduce the viscosity of the hydraulic oil, affecting the performance of the hydraulic system, reducing its power transmission and lubrication effects, and increasing the risk of leakage, ultimately leading to a sharp drop in drive efficiency and frequent equipment failures, affecting production operations. The existing cooling structure is usually unable to cool the inside and outside of the motor at the same time. Two cooling structures are set to cool the inside and outside of the motor respectively, which makes the overall motor larger and too cumbersome to be used in some special scenarios. There is an urgent need for a structure with a simple structure that can cool the inside and outside of the motor at the same time. Therefore, we propose a hydraulic high-efficiency drive motor that is easy to dissipate heat. Summary of the invention

[0044] A water cooling assembly 33, which is disposed inside the shield 31, and both ends of the water cooling assembly 33 pipeline penetrate the shield 31 and are connected to a water tank outside the shield 31;

[0045] An oil cooling assembly 34, which is arranged inside the shield 31, and the pipeline of the oil cooling assembly 34 is sleeved outside the pipeline of the water cooling assembly 33, one end of the oil cooling assembly 34 passes through the shield 31 for connecting to the oil tank, and the other end of the oil cooling assembly 34 extends to the inside of the motor body 1 for connecting to the hydraulic system of the motor body 1;

[0046] An air cooling assembly 36 is disposed inside the shield 31 and is fixedly connected to one end of the rotating shaft 2 close to the shield 31. Pipes of the water cooling assembly 33 and the oil cooling assembly 34 are disposed around the outside of the air cooling assembly 36.

Then the high-temperature oil enters the oil cooling component 34, and then enters the inside of the oil tank. After external circulation, it returns to the inside of the motor body 1. After the air cooling component 36 is started, the tail of the motor body 1 is cooled, and at the same time, the air is driven to flow outside the oil cooling component 34 to cool the high-temperature oil, cool the oil that is re-input into the motor body 1, and cool the structure that the oil contacts.

The air flows along the motor body 1 to the rear end The air is blown in the direction of the cover 35, and the gas between the rear end cover 35 and the shield 31 flows, and the pressure is reduced, which drives the gas flow in the gap between the motor body 1 and the heat sink 321, radiates the heat dissipation effect of the air cooling component 36 to the entire motor body 1, and drives the pressure on the side where the water tank is connected to the lower circulation pipe 333 to rise. The cooling water passes through the upper and lower circulation pipes 333, the water cooling pipe 331, and the upper circulation pipe 332 in turn, and finally returns to the inside of the water tank for cooling, and cools the inside of the shield 31. The cooling water flows inside the water cooling pipe 331 in the oil cooling pipe 341 to cool the inside of the hydraulic oil.
