Description

Technical Field

[0001] This utility model relates to the field of linear bearings, specifically a floating aluminum alloy linear bearing. Background Technology

[0002] Linear bearings are used in various mechanical equipment to achieve linear reciprocating motion, reducing friction and improving motion accuracy. Traditional linear bearings are mostly made of steel, which has high strength and wear resistance. Existing aluminum alloy linear bearings are usually installed in a fixed manner during use. In complex working environments, such as those with temperature changes or external impacts, linear bearings lack effective self-adjustment capabilities and cannot be floated after installation, making them inconvenient to use. Furthermore, these bearings require regular manual lubrication and maintenance, reducing worker efficiency. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a floating aluminum alloy linear bearing, comprising a main frame, a central groove in the middle of the main frame, a connecting top block inside the central groove, and a rotating shaft inserted through the central part of the connecting top block. The connecting top block is rotatably connected to the central groove via the rotating shaft, and a bearing seat is fixedly connected to the bottom of the connecting top block. A bearing body is fixedly installed inside the bearing seat. An oil pump is fixedly installed on one side of the bottom of the main frame, and an oil inlet pipe is fixedly connected to the input end of the oil pump. A drip nozzle is fixedly installed on the side of the bottom of the main frame near the bearing body, and an oil delivery pipe is fixedly connected to the input end of the drip nozzle. One end of the oil delivery pipe is fixedly connected to the output end of the oil pump.

[0005] As a preferred technical solution of this utility model, the oil pump is electrically connected to an external power supply through an external controller. Positioning grooves corresponding to the rotating shaft are opened on both sides of the main frame. The rotating shaft is rotatably connected to the inside of the positioning groove. An offset groove corresponding to the bearing seat is provided at the bottom of the main frame. The bearing seat is located inside the offset groove. A reinforcing beam is fixedly connected to the top of the back of the main frame. Diagonal bracing plates are fixedly connected to both sides of the reinforcing beam.

[0006] As a preferred technical solution of this utility model, several fixing holes are provided on both sides of the main frame, the middle groove corresponds to the bearing seat, the end of the oil delivery pipe away from the drip nozzle is connected to the output end of the oil pump, and one end of the oil inlet pipe is connected to an external oil source.

[0007] As a preferred embodiment of this utility model, the bearing body includes a base material layer and an anti-corrosion layer. The outer side of the base material layer is coated with an anti-corrosion layer. The base material layer is made of aluminum alloy, and the anti-corrosion layer is made of ceramic coating. The anti-corrosion layer improves the corrosion resistance of the bearing body and reduces corrosion damage.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] The bearing body is embedded inside the bearing housing, and the connecting top block is rotatably mounted inside the central groove of the main frame via a rotating shaft, allowing the main frame of the entire linear bearing to rotate at a certain angle, allowing for a certain degree of angle compensation.
