Description

Technical Field

[0001] The invention relates to a lubrication sealing device of an integral bearing seat, belonging to the technical field of machinery. Background Art

[0002] For the bearing structure that uses the bearing as the fulcrum on the shaft, it is often necessary to consider the bearing's lubrication, sealing, fixing, and temperature detection methods. A good bearing structure layout is not only conducive to improving the bearing life, but also conducive to the maintenance and repair of the bearing. The traditional bearing seat structure generally uses contact or non-contact seals for the bearing. Contact seals are easy to damage the sealing device and are inconvenient to repair, so they are not suitable for use. The labyrinth seal in the non-contact seal is generally suitable for split bearing seats, but there is a risk of oil leakage, especially oil injection lubrication. Therefore, any of the above single sealing structures has the risk of poor sealing effect. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a lubrication, oil return, sealing and temperature detection device for an integral bearing seat in view of the defects in the prior art.

[0004] To solve this technical problem, the present invention provides an integral bearing seat lubrication and sealing device, comprising an integral bearing seat, a left oil slinger, a left end cover, a left oil slinger two, a left oil slinger one, a bearing, a right oil slinger one, a right oil slinger two, a right end cover, a right oil slinger, a sealing ring, a temperature detection device and a shaft, wherein the bearing is mounted on the shaft and arranged in the integral bearing seat, and the inner ring of the bearing is axially positioned by the left oil slinger and the right oil slinger mounted on the shaft, and the left oil slinger and the right oil slinger are respectively provided with the left oil slinger two and the right oil slinger two; the left oil slinger one and the right oil slinger one arranged at both ends of the bearing are mounted in the integral bearing seat, and are positioned by the left end cover and the right end cover respectively; the left end cover and the right end cover are fixed at both ends of the integral bearing seat; and the temperature detection device is mounted on the integral bearing seat.

[0005] The left oil slinger ring, the left end cover, the second left oil baffle ring, the first left oil baffle ring, the first right oil baffle ring, the second right oil baffle ring, the right end cover and the right oil slinger ring are all provided with sealing ring grooves, and sealing rings are installed in the sealing ring grooves.

[0006] The integral bearing seat is provided with two oil inlet positions, a first oil inlet and a second oil inlet, and two oil return modes, axial oil return from the first oil return port and radial oil return from the second oil return port, to meet the requirements of horizontal and vertical installation of the integral bearing seat.

[0007] The sealing ring comprises a first sealing ring, a second sealing ring, a third sealing ring and a fourth sealing ring which are arranged symmetrically on the left and right sides; three layers of sealing devices are respectively installed on the left and right sides of the bearing in the integral bearing seat: the first layer is a left oil retaining ring 1 and a left oil throwing ring, and the left oil throwing ring is provided with an oil throwing groove, and the first layer is axially sealed by the first sealing ring and the third sealing ring; the second layer is a left oil retaining ring 2, and axially sealed by the second sealing ring; the third layer is a left end cover, and axially sealed by the fourth sealing ring and the oil throwing groove.

[0008] The left and right sides of the bearing in the integral bearing seat are respectively provided with four layers of oil return chambers: a first oil return chamber, a second oil return chamber, a third oil return chamber, and a fourth oil return chamber. The lubricating oil flows from the first oil return chamber into the first oil return port or the second oil return port for oil return. When the lubricating oil leaks, the leaked lubricating oil is guided back to the first oil return port for oil return through the second oil return chamber, the third oil return chamber, and the fourth oil return chamber in sequence.

[0009] After the lubricating oil enters the integral bearing seat, it first passes through the first sealing ring and the third sealing ring to axially seal the lubricating oil in the first oil return chamber. During normal operation, most of the lubricating oil can flow from the first oil return chamber to the first oil return port or the second oil return port; when some of the lubricating oil penetrates through the left oil retaining ring 1 or penetrates into the second oil return chamber, the leaked oil in the second oil return chamber can be guided to the first oil return port; when some of the lubricating oil in the second oil return chamber passes through the second sealing ring on the left oil retaining ring 2 again to enter the third oil return chamber, the leaked lubricating oil can also flow back to the first oil return port from the third oil return chamber; even if a small amount of lubricating oil in the third oil return chamber enters the fourth oil return chamber through the oil throwing groove in the end, the oil in the fourth oil return chamber can also flow back to the first oil return port, and the fourth sealing ring can perform axial sealing when the lubricating oil in the second oil return chamber, the third oil return chamber and the fourth oil return chamber flows to the first oil return port; at the same time, a temperature detection device is installed on the integral bearing seat to detect the temperature of the bearing.

[0010] Beneficial effects: The present invention can effectively lubricate and dissipate heat for the bearing, prevent the lubricating oil from leaking outward, and provide good and reliable bearing sealing. BRIEF DESCRIPTION OF THE DRAWINGS

During normal operation, most of the lubricating oil can flow from the first oil return chamber C to the first oil return port B1 or the second oil return port B2; when some of the lubricating oil penetrates or enters the second oil return chamber D through the left oil retaining ring 5, the leaked oil in the second oil return chamber D can be guided to the first oil return port B1; when part of the lubricating oil in the second oil return chamber D passes through the second sealing ring 1102 on the left oil retaining ring 24 again and enters the third oil return chamber E, the leaked lubricating oil can also flow back to the first oil return port B1 from the third oil return chamber E; finally, even if a small amount of lubricating oil in the third oil return chamber E enters the fourth oil return chamber F through the oil throwing groove S, the oil in the fourth oil return chamber F can also flow back to the first oil return port B1, and when the lubricating oil in the second oil return chamber D, the third oil return chamber E and the fourth oil return chamber F flows to the first oil return port B1, the fourth sealing ring 1104 can perform axial sealing. Through the above working process, the integral bearing seat 1 can achieve a good sealing effect, that is, it ensures the lubrication of the bearing 6 and reduces the temperature. At the same time, a temperature detection device 13 is installed on the integral bearing seat 1 to detect the temperature of the bearing 6.
