Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, specifically to an oil bath lubricated belt conveyor roller device. Background Technology

[0002] Belt conveyor rollers are widely used in industrial fields. Traditional rollers have bearing housings on both sides, and bearings are installed in the bearing housings. These bearings require regular lubrication and maintenance, and the lubricating grease is greatly affected by temperature. Different greases are often selected according to different seasons and are not suitable for high-temperature environments.

[0003] A belt conveyor roller, as disclosed in Chinese Utility Model Patent Publication No. CN220555527U, includes a roller body, a strong magnetic shaft assembly, and a drive unit. The strong magnetic shaft assembly includes a roller rotation unit and a high-magnetic rotation unit. The high-magnetic rotation unit is arranged opposite to the roller rotation unit. The roller rotation unit is connected to the roller body, and the high-magnetic rotation unit is connected to the drive unit. The drive unit of this utility model drives the high-magnetic rotation unit to rotate, thereby driving the roller rotation unit to rotate, which in turn drives the roller body to rotate. This utility model, through the strong magnetic shaft assembly, enables contactless rotation between the drive unit and the roller body, achieving flexible start-up, eliminating the need for a coupler motor, reducing drive unit overload, and improving equipment protection.

[0004] The telescopic head roller of the sintering mixer is placed inside the mixer for a long time. Its working environment temperature is high, and the operating status of the roller cannot be checked during operation. The main problem is that it is impossible to predict the defects in the rolling bearing. Often, the damaged part and cause can only be determined after an accident occurs. Accidents can cause production delays or even secondary accidents (such as fires or belt wear and breakage). Utility Model Content

[0005] The purpose of this utility model is to provide an oil bath lubricated belt conveyor roller device to improve equipment stability, avoid production bottlenecks, and reduce downtime due to accidents.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an oil bath lubricated belt conveyor roller device, comprising a fixed shaft; two bearing bodies symmetrically sleeved on the fixed shaft; two bearing covers symmetrically provided on opposite sides of the two bearing bodies via spacers, and the bearing covers are connected to the fixed shaft via oil seals; an internal bearing seat is sleeved on the outer ring of the bearing body; a hub body is fixedly connected to the outer surface of the internal bearing seat via a hub weld, and the two hub bodies are connected via a roller surface; an annular oil separator is fixedly provided inside the roller surface; an oil pool is formed between the fixed shaft, bearing bodies, bearing covers, internal bearing seat, hub body, roller surface, and annular oil separator.

[0007] Preferably, two shaft supports are symmetrically fitted on the fixed shaft, and the fixed shaft and the shaft supports are connected by a key.

[0008] Preferably, temperature measuring holes are provided on both sides of the fixed shaft and thermocouples are installed thereon.

[0009] Preferably, two felt covers are symmetrically fixed on opposite sides of the two bearing covers, and the felt covers are connected to the fixed shaft through the felt body.

[0010] Preferably, the surface of the roller is coated with a roller vulcanized rubber surface.

[0011] Preferably, the wheel hub body has at least one oil injection hole, and a piston is provided on the oil injection hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention uses thin oil for lubrication, which can extend the oil replenishment cycle to 1 year. The roller can withstand a heat temperature of up to 80℃. The bearing operating temperature is detected by thermocouples, which can avoid routine inspections. In the event of damage to the built-in bearing body, belt misalignment will not contact the heat point, thus avoiding fire accidents.

The built-in bearing body 8 is lubricated by the lubricating oil in the oil pool 18. A hole is drilled at the center point of the end of the central shaft to the inner ring of the bearing body 8. A thermocouple 17 is led out from the inner ring of the bearing body 8 to detect the operating temperature of the bearing body 8. The thermocouple 17 is connected to the high temperature alarm device and interlocked with the belt conveyor. If the operating temperature exceeds the standard, the belt conveyor will stop. In addition, lubricating oil is added to the lower surface of the shaft through the oil injection hole 16. The two bearing bodies 8 on both sides share an oil pool 18. The drum is supported by a fixed shaft 1. Temperature measuring holes are set on both sides of the fixed shaft 1 and thermocouples 17 are installed to monitor the operating temperature of the bearing body 8.
