Description

Technical Field

[0001] The utility model relates to the technical field of double-bearing oil pumps, and specifically to a double-bearing oil pump. Background Technique

[0002] A double-bearing oil pump is a type of oil pump with a special structural design. It uses two bearings to support the shaft of the oil pump. Compared with a single-bearing oil pump, the double-bearing design can provide better stability and reliability, reduce the wobbling and wear of the shaft, thereby improving the working efficiency and service life of the oil pump.

[0003] When using this double-bearing oil pump, the drive shaft of the internal gear includes the shaft end, the intermediate gear, and the shaft tail. The three points need to be very concentric to ensure the quality of the pump. If there is any inclination, it may jam the internal gear ring, it may jam the oil-sealing crescent plate, and it may rub against the two end faces. At the same time, the internal gear pump outputs power at the shaft end, which will inevitably cause the tail end to lift up, forming an axial force. If a traditional bushing is used, it will accelerate wear. Therefore, we have proposed the double-bearing oil pump. Content of the Utility Model

[0004] The purpose of the present utility model is to provide a double-bearing oil pump to solve the problems raised in the above-mentioned background technology. For the transmission shaft of the internal meshing gear, the split shaft end, the intermediate gear, and the shaft tail, the three points must be very concentric to ensure the quality of the pump. If there is any inclination, it may jam the internal gear ring, it may jam the oil-sealing crescent plate, and it may rub against the two end faces. At the same time, the internal meshing gear pump outputs power at the shaft end, which will inevitably cause the tail end to lift up, forming an axial force. If a traditional bushing is used, it will accelerate wear. To achieve the above purpose, the present utility model provides the following technical solutions: A double-bearing oil pump, including a device main body, a connecting piece is fixedly connected to the top of the device main body, a connecting column is movably connected inside the connecting piece, a gear is sleeved on the side surface of the connecting column, a fixed chassis is fixedly connected to the bottom of the device main body, a ball bearing is fixedly connected to the top of the fixed chassis, a sleeve is inserted inside the bearing, an arc-shaped baffle is fixedly connected to the inner wall of the device main body, a toothed ring is fixedly connected to the side surface of the arc-shaped baffle, a first annular sleeve is fixedly connected inside the connecting piece, a closed annular sleeve is fixedly connected inside the connecting piece, a fixed bearing is fixedly connected inside the connecting piece, a connecting pipe is inserted inside the fixed bearing, and a sealing gasket is fixedly connected to the side surface of the connecting pipe. When using this double-bearing oil pump, the gear is driven to rotate by the connecting column. When the gear rotates, the teeth of the gear gradually disengage from the meshing, forming a partial vacuum. The liquid is sucked into the tooth space under the action of the external pressure. As the gear continues to rotate, the tooth space gradually decreases, and the liquid is squeezed and discharged from the outlet of the oil pump. At the same time, the function of the ball bearing and the fixed bearing is to provide stable support for the rotating components, ensuring that they maintain an accurate position and movement trajectory during high-speed rotation, thereby ensuring the normal oil suction and oil discharge actions of the oil pump. At the same time, the ball bearing and the fixed bearing provide stable support and guidance for these movements.

[0005] Further preferably, the connecting column sequentially penetrates through the connecting piece and the device main body. The double-bearing support structure makes the oil pump shaft more stable during operation, reduces the shaft wobbling and vibration, and helps to maintain the accurate working state of the oil pump.

[0006] Further preferably, the fixed bearing, the connecting pipe, and the sealing gasket are respectively sleeved on the side surface of the connecting column. The stable shaft support can effectively reduce the friction and wear between the shaft and other components, and extend the service life of the oil pump.

[0007] Further preferably, the fixed bearing, the connecting pipe, and the sealing gasket are located on the side surface of the gear. The double-bearing design enhances the reliability of the oil pump under long-term operation and complex working conditions, and reduces the probability of failures.

[0008] Further preferably, the gear is located inside the toothed ring and the toothed ring meshes with the gear. The arc-shaped baffle is arc-shaped. The closed annular sleeve is sleeved on the side surface of the connecting column, which can provide oil pressure more stably, reduce the fluctuation of the oil pressure, and thus ensure the normal operation of the lubrication or hydraulic system.

[0009] Further preferably, the closed annular sleeve is located at the bottom side of the gear. The sleeve is sleeved on a section of the bottom end of the connecting column, which can better withstand larger loads and pressures, is suitable for high-power and high-performance equipment. The stable operation helps to reduce the noise generated during the operation of the oil pump. The stable shaft helps to maintain a good sealing effect, reduce the possibility of leakage, and improve the working efficiency of the oil pump.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] In the present utility model, when using the double-bearing oil pump, the gear is driven to rotate by the connecting column. When the gear rotates, the teeth of the gear gradually disengage from the meshing, forming a partial vacuum. The liquid is sucked into the tooth space under the action of the external pressure. As the gear continues to rotate, the tooth space gradually decreases, and the liquid is squeezed and discharged from the outlet of the oil pump. At the same time, the functions of the ball bearing and the fixed bearing are to provide stable support for the rotating components, ensure their accurate positions and movement trajectories during high-speed rotation, thereby ensuring the normal oil suction and oil discharge actions of the oil pump. At the same time, the ball bearing and the fixed bearing provide stable support and guidance for these movements.

When using this double-bearing oil pump, the gear 4 is driven to rotate by the connecting column 3. When the gear 4 rotates, the teeth of the gear 4 gradually disengage from the meshing, forming a partial vacuum. The liquid is sucked into the tooth space under the action of external pressure. As the gear 4 continues to rotate, the tooth space gradually decreases, and the liquid is squeezed and discharged from the outlet of the oil pump. At the same time, the functions of the ball bearing 6 and the fixed bearing 12 are to provide stable support for the rotating components, ensuring that they maintain an accurate position and motion trajectory during high-speed rotation, thereby guaranteeing the normal oil suction and oil discharge actions of the oil pump.

The stable operation helps to reduce the noise generated during the operation of the oil pump. The stable shaft helps to maintain a good sealing effect, reduces the possibility of leakage, and improves the working efficiency of the oil pump.

[0023] The usage method and advantages of the present utility model: For this double-bearing oil pump, during use, the working process is as follows:

[0024] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown, when using this double-bearing oil pump, the gear 4 is driven to rotate by the connecting column 3. When the gear 4 rotates, the teeth of the gear 4 gradually disengage from the meshing, forming a partial vacuum. The liquid is sucked into the tooth space under the action of external pressure. As the gear 4 continues to rotate, the tooth space gradually decreases, and the liquid is squeezed and discharged from the outlet of the oil pump.

At the same time, the ball bearing 6 and the fixed bearing 12 provide stable support and guidance for these movements. The support structure of the double bearings makes the oil pump shaft more stable during operation, reducing the shaft's wobbling and vibration, helping to maintain the accurate working state of the oil pump. The stable shaft support can effectively reduce the friction and wear between the shaft and other components, extending the service life of the oil pump. The double-bearing design enhances the reliability of the oil pump under long-term operation and complex working conditions, reducing the probability of failures, being able to provide oil pressure more stably, reducing the fluctuation of the oil pressure, thereby ensuring the normal operation of the lubrication or hydraulic system, being able to better withstand larger loads and pressures, and being applicable to high-power and high-performance equipment.
