Technical Field
[0001] This application relates to the technical field of oil bath lubrication, and particularly to an oil injection device. Background Art
[0002] The horizontal rotating equipment with oil bath lubrication is mainly driven by a drive motor to drive the shaft and impeller to rotate at high speed to do work for energy conversion. In order to reduce the energy loss of the shaft, a bearing is installed on the shaft. A large amount of heat is generated when the bearing rotates at high speed, and lubrication and cooling are required to maintain the temperature stability. Oil bath lubrication is the most common and cost-effective bearing lubrication method. Oil bath lubrication requires regular oil change and replenishment, so the oil injection device is an indispensable part.
[0003] Since the inside of the bearing body is a closed space, the exhaust performance of the existing oil injection device is not good, and the generated hot air flow will accumulate above the bearing body, resulting in a gradual increase in pressure, which causes the lubricating oil to leak from the constant-level oil cup or the two-end oil seal parts.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.
[0020] As Figures 1 - 4 shown, the embodiments of the present utility model provide an oil injection device, which includes an oil injection cup 1, an intermediate partition 2, a flocculent filter element 3, and an oil injection cap 4.
[0021] In practical applications, the lower end of the oil injection cup 1 is connected to the bearing body. Specifically, the lower end of the oil injection cup 1 is provided with an external thread, so that the oil injection cup 1 can be threadedly connected to the bearing body through the external thread at its lower end, thereby ensuring the internal communication between the oil injection cup 1 and the bearing body.
[0022] As Figure 3As shown in the figure, the middle partition 2 is arranged in the inner cavity of the oil filling cup 1 and divides the oil filling cup 1 into an exhaust chamber 11 and an oil filling chamber 12. The top end of the middle partition 2 is lower than the top end of the oil filling cup 1 to enable the exhaust chamber 11 and the oil filling chamber 12 to communicate. An exhaust hole 111 is provided on the exhaust chamber 11. An oil filling hole 121 is provided at the bottom of the oil filling chamber 12, and the oil filling hole 121 communicates with the inside of the bearing body. Specifically, when filling oil, pouring lubricating oil into the oil filling chamber 12 can achieve oil filling. In addition, the hot air flow generated during the operation of the horizontal rotating equipment enters the oil filling chamber 12 through the oil filling hole 121, then enters the exhaust chamber 11 through the oil filling chamber 12, and finally is discharged into the atmosphere from the exhaust hole 111 to ensure that the hot air flow of the horizontal rotating equipment can be smoothly discharged, thereby increasing the exhaust performance of the oil filling device and further avoiding oil leakage of the oil bath lubricated horizontal rotating equipment.
[0023] As Figure 1 shown in the figure, the flocculent filter element 3 is arranged in the exhaust chamber 11. Specifically, arranging the flocculent filter element 3 can prevent dust from entering the exhaust chamber 11 through the exhaust hole 111, thereby preventing dust from spreading into the oil filling chamber 12 and polluting the oil filling chamber 12.
[0024] Continue to refer to Figure 1 shown in the figure, the oil filling cover 4 is detachably connected to the top of the oil filling cup 1. In practical applications, the oil filling cover 4 is provided with internal threads, and the top of the oil filling cup 1 is provided with external threads. When oil filling is not required, the oil filling cover 4 and the oil filling cup 1 are connected by threads, and when oil filling is required, the oil filling cover 4 is unscrewed to prevent impurities such as dust and rainwater from entering the oil filling cup 1 and polluting the lubricating oil, thereby ensuring the cleanliness inside the oil filling cup 1.
[0025] An embodiment of the present invention provides an oil filling device, which includes an oil filling cup 1, a middle partition 2, a flocculent filter element 3 and an oil filling cover 4. The lower end of the oil filling cup 1 is connected to the bearing body. The middle partition 2 is arranged in the inner cavity of the oil filling cup 1 and divides the oil filling cup 1 into an exhaust chamber 11 and an oil filling chamber 12. The top end of the middle partition 2 is lower than the top end of the oil filling cup 1 to enable the exhaust chamber 11 and the oil filling chamber 12 to communicate. An exhaust hole 111 is provided on the exhaust chamber 11. An oil filling hole 121 is provided at the bottom of the oil filling chamber 12, and the oil filling hole 121 communicates with the inside of the bearing body. The flocculent filter element 3 is arranged in the exhaust chamber 11. The oil filling cover 4 is detachably connected to the top of the oil filling cup 1. When filling oil in the oil filling device of the present application, pouring lubricating oil into the oil filling chamber 12 can achieve oil filling. In addition, the hot air flow generated during the operation of the horizontal rotating equipment enters the oil filling chamber 12 through the oil filling hole 121, then enters the exhaust chamber 11 through the oil filling chamber 12, and finally is discharged into the atmosphere from the exhaust hole 111 to ensure that the hot air flow of the horizontal rotating equipment can be smoothly discharged, thereby increasing the exhaust performance of the oil filling device and further avoiding oil leakage of the oil bath lubricated horizontal rotating equipment.
[0026] As Figure 3As shown, the exhaust hole 111 is located at the bottom of the exhaust chamber 11. In practical applications, the exhaust hole 111 can also be provided at the top or side of the exhaust chamber 11. However, when the exhaust hole 111 is provided at the top of the exhaust chamber 11, rainwater or other splashing liquids may enter the bearing body when the horizontal rotating device is installed in an outdoor environment, resulting in emulsification of the lubricating oil. When the exhaust hole 111 is provided at the side of the exhaust chamber 11, if a fan is installed near the horizontal rotating device, it may cause poor exhaust of the oil injection device. Therefore, the exhaust hole 111 is provided at the bottom of the exhaust chamber 11 to avoid the above problems.
[0027] Continue to refer to Figure 1 As shown, the oil injection device further includes a ventilation pipe 5. The ventilation pipe 5 is arranged in the oil injection cup 1. One end of the ventilation pipe 5 is communicated with the oil injection hole 121, and the other end of the ventilation pipe 5 passes through the flocculent filter element 3 and is communicated with the exhaust hole 111. In practical applications, when the flocculent filter element 3 adsorbs too many impurities, its ventilation performance will deteriorate. If the flocculent filter element 3 is not replaced in time, the exhaust effect of the oil injection device will deteriorate. Therefore, the ventilation pipe 5 is provided to introduce the hot air flow generated during the operation of the horizontal rotating device into the ventilation pipe 5 through the oil injection hole 121, and then discharge it into the atmosphere from the exhaust hole 111 through the ventilation pipe 5, thereby increasing the exhaust performance of the oil injection device. Specifically, the size of the ventilation pipe 5 can be set according to the size of the bearing body oil chamber and the temperature rise of the lubricating oil to ensure that the effect of complete exhaust can be achieved.
[0028] Specifically, the flocculent filter element 3 includes cotton. Of course, the flocculent filter element 3 can also be a fluff with good air permeability such as space cotton or steel wool.
[0029] As Figure 1 As shown, the oil injection device further includes a filter screen 6. The filter screen 6 is located in the oil injection chamber 12 and is detachably connected to the middle partition 2. The filter screen 6 can filter impurities in the lubricating oil during oil injection to ensure the cleanliness of the lubricating oil, prevent impurities from entering the bearing and accelerating the wear of the bearing, thereby extending the service life of the bearing. Specifically, the bottom of the filter screen 6 cannot contact the bottom of the oil injection chamber 12 to avoid blockage of the filter screen 6 and poor exhaust of the oil injection device. In practical applications, the filter screen 6 is suspended on the middle partition 2 by setting a buckle or fixed on the middle partition 2 by screws 7, so as to be removed in time for cleaning when there are impurities in the filter screen 6.
[0030] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other, and the key points of each embodiment are the differences from other embodiments.
