Description

Technical Field

[0001] The utility model relates to the technical field of centrifuges, and particularly relates to an oil filling device for a centrifuge supporting wheel. Background Art

[0002] A cast pipe centrifuge is a device specifically used for producing centrifugally cast pipes. Through a rapidly rotating mold, the liquid metal injected into it generates a centrifugal motion, thereby filling the mold and forming a casting. This process utilizes centrifugal force to fully fill the mold with liquid metal in the radial direction and form a free surface of the casting, enabling a cylindrical inner hole to be obtained without using a core.

[0003] For example, the Chinese patent document with the authorization announcement number CN101298100B discloses a hot mold casting steel pipe centrifuge. The steel pipe centrifuge includes an equal - amount pouring device, a centrifuge main body, a pipe pushing device, a pipe supporting device, and a pipe receiving device. A ladle fixing frame is fixed on the frame of the equal - amount pouring device, an isochronous plate is fixed on the ladle fixing frame, and a ladle with a long pouring channel is fixed on the frame; the main body supporting wheel group of the centrifuge main body is driven by a motor, and the main body supporting wheel group supports the pipe mold; on the support frame of the pipe pushing device, a push rod is fixed through a guide rail, and the push rod is driven by a motor through pin - tooth transmission, used for separating the steel pipe blank from the pipe mold, cleaning the inner wall of the pipe mold, and spraying a coating on the inner wall of the pipe mold; the pipe supporting device ensures the separation of the steel pipe blank from the pipe mold; the pipe receiving device catches the steel pipe blank separated by the pipe pushing device. This device can obtain a hollow steel pipe blank with excellent organization and precise dimensions, has a high comprehensive material yield, and realizes the whole - machine automated production.

[0004] However, the above - mentioned centrifuge still has certain defects: during the operation of the centrifuge, the high - speed rotating pipe mold is carried by the supporting wheels, and lubricating oil needs to be regularly injected into the bearing seats of the supporting wheels. When the above - mentioned centrifuge is in use, it usually injects oil into the bearings uniformly through a distributor. Due to the long oil injection pipeline, the distributor often has the phenomenon of oil circuit blockage, which in turn causes the supporting wheel bearings to wear or even be damaged due to lack of oil, shortening the service life of the supporting wheels and reducing the production efficiency. Summary of the Utility Model

[0005] The utility model provides an oil filling device for a centrifuge supporting wheel to solve the technical problem that the supporting wheels are damaged due to lack of oil caused by the failure of the distributor during the operation of the centrifuge, resulting in reduced production efficiency.

[0006] To solve the above problems, the oil filling device for a centrifuge supporting wheel provided by the utility model adopts the following technical solutions:

There is a bearing between the supporting wheel and the wheel seat. An oil filling assembly for supplying oil to the bearing is provided on one side of the wheel seat. The side where the oil filling assembly is located is defined as the front side. The oil filling assembly includes a lubricating oil tank located at the front side of the pipe mold. A oil pump is provided in the lubricating oil tank. The right end of the oil pump has a main oil filling pipe. A plurality of sub-oil filling pipes corresponding to each bearing are provided on the main oil filling pipe. Each sub-oil filling pipe is fixedly connected to the wheel seat.

[0010] Further, the wheel seat is of a concave structure. The bearings are located at the left and right ends of each wheel seat. The left and right ends of the supporting wheel shaft are respectively installed in the bearings at the left and right ends of the corresponding wheel seat.

[0025] The main concept of the present invention is to replace the distributor by setting the main oil filling pipe 63 and the branch oil filling pipe 64 fixedly connected to the wheel seat 3, which avoids the lack of oil in the supporting wheel 4 and reduces the danger of the refueling operation of the operators; the setting of the control valve 65 enables the device to quantitatively control the refueling volume, reduces the labor intensity of the operators, and improves the convenience of operation.
