Description
Technical Field
The utility model relates to a thrust tile structure. The method is suitable for the technical field of generator equipment.
Background
In the process of starting and stopping the generator at a low speed, an oil film is difficult to build between the mirror plate and the thrust bearing, so that the thrust bearing is in a semi-dry friction state, and abrasion accidents are easy to occur. In order to reduce static friction torque, a high-pressure oil jacking load-reducing system is generally adopted, and a continuous oil film is formed on the tungsten-gold layer. At present, a ring-shaped or circular oil groove is formed in a tungsten-gold layer in a high-pressure oil jacking structure, but when thrust load is large, an oil film is difficult to uniformly build, and the situation that a local oil film is thin occurs.
Disclosure of Invention
The utility model aims to solve the technical problems that: in order to solve the problem of uneven oil film between the thrust bearing and the mirror plate, the utility model provides a thrust tile structure which enables oil films on an UJIN layer to be evenly distributed.
The technical scheme adopted by the utility model is as follows: a thrust tile structure installs and is used for constituteing thrust bearing with thrust disc on thrust disc, its characterized in that: the oil groove is communicated with a main oil pipe arranged in the thrust tile body through an oil separating branch pipe, the end part of the main oil pipe is arranged on the cambered surface of one side, facing the outside of the thrust disc, of the thrust tile body, and the end part of the main oil pipe is connected with an oil supply system through an outer joint. Therefore, when the thrust bearing works, the oil supply system supplies oil into the main oil pipe and is uniformly distributed on the UJIN layer through the oil dividing branch pipe and the oil groove, so that the lubricating oil forms a uniform oil film between the thrust bearing and the mirror plate.
Two oil grooves are arranged on the Uygur autonomous region along the radial direction of the circle where the fan-shaped Uygur autonomous region is located, the two oil grooves are respectively arranged at 1/3 and 2/3 positions of the Uygur autonomous region, the oil groove arranged on the thrust tile body towards the outer side of the thrust disc is an outer oil groove, and the oil groove arranged on the thrust tile body towards the inner side of the thrust disc is an inner oil groove.
The length of the groove is 6cm-10cm, and the length of the inner oil groove is 2/3 of that of the outer oil groove. Therefore, the area of the fan-shaped Uygur autonomous region facing the outer side of the thrust disc is larger, the area of the fan-shaped Uygur autonomous region facing the inner side of the thrust disc is smaller, and the length of the inner oil groove is smaller than that of the outer oil groove, so that more lubricating oil flows out from the outer oil groove to the Uygur autonomous region outside the thrust disc than from the inner oil groove to the Uygur autonomous region inside the thrust disc, and an oil film between the thrust bearing and the mirror plate is more uniform.
The thickness of the Uygur autonomous region is 5mm-10mm, and the depth of the oil groove is 1/2 of the thickness of the Uygur autonomous region.
The inner diameter of the oil distributing branch pipe is 1/2 of the inner diameter of the main oil pipe.
The beneficial effects of the utility model are as follows: the utility model can adapt to the large thrust load of the generator and generate a uniform oil film at the stress concentration position between the thrust bearing and the mirror plate; the utility model has simple structure and less influence on the thrust tile body and the wujin layer.

Detailed Description
The present utility model will be described in further detail by way of examples with reference to the accompanying drawings, which are illustrative of the present utility model and not limited to the following examples.
The embodiment is a thrust tile structure, which is applied to a thrust bearing of a generator. The thrust bearing consists of a thrust disc and a thrust tile body 2 which is arranged on the thrust disc along the circumferential direction of the circle, and lubricating oil forms an oil film between the thrust bearing and the mirror plate in the running process of the generator.
In this embodiment, the surface of the thrust tile body 2 is provided with the wujin layer 1, and the surfaces of the thrust tile body 2 and the wujin layer 1 are both fan-shaped. The main oil pipe 3 is arranged in the thrust tile body 2 along the radial direction of the circle where the fan-shaped thrust tile body 2 is located at the middle position of the circle where the fan-shaped thrust tile body 2 is located in the circumferential direction, the end part of the main oil pipe 3 is arranged on the surface of the thrust tile body 2 facing to one side of the outer side of the thrust disc when the thrust tile body 2 is arranged on the thrust disc, the outer joint 7 is arranged on the end part of the main oil pipe 3, the outer joint 7 is connected with the oil supply system, and the oil supply system supplies oil to the main oil pipe 3 through the outer joint 7.
In this embodiment, two oil grooves are arranged in the center position of the thrust tile body 2 along the circumferential direction of the circle where the fan-shaped thrust tile body 2 is located along the radial direction of the circle where the fan-shaped thrust tile body 2 is located, the two oil grooves are respectively arranged at 1/3 and 2/3 positions of the wujin layer 1, the oil groove arranged on the thrust tile body 2 towards the outer side of the thrust disc is an outer oil groove 5, and the groove length of the outer oil groove 5 is 6cm-10cm. The oil groove arranged on the thrust tile body 2 towards one side in the thrust disc is an inner oil groove 6, and the groove length of the inner oil groove 6 is 2/3 of the groove length of the outer oil groove 5. The outer oil groove 5 and the inner oil groove 6 are arranged along the radial direction perpendicular to the circle where the fan-shaped wujin layer 1 is positioned. Wherein the thickness of the Uygur autonomous region 1 is 6mm-10mm, and the groove depth of the outer oil groove 5 and the inner oil groove 6 is 1/2 of that of the Uygur autonomous region 1.
In this embodiment, the outer oil gallery 5 and the inner oil gallery 6 are both in communication with the main oil pipe 3 via the oil separating branch pipe 4. Wherein the inner diameter of the oil distribution branch pipe 4 is 1/2 of the inner diameter of the main oil pipe 3. Thus, when the oil supply system supplies oil to the inner oil groove 6 and the outer oil groove 5 through the main oil pipe 3 and the oil distribution branch pipe 4, the area of the outer oil groove 5 at the position of the gold layer 1 is larger, the area of the inner oil groove 6 at the position of the gold layer 1 is smaller, and the length of the outer oil groove 5 is longer than that of the inner oil groove 6, so that the lubricating oil flowing out of the outer oil groove 5 is more than that flowing out of the inner oil groove 6, the lubricating oil flowing out of the outer oil groove 5 and the inner oil groove 6 to the surface of the gold layer 1 can be uniformly smeared on the gold layer 1, and in the running process of the generator, the lubricating oil can generate a uniform oil film between the thrust bearing and the mirror plate.
