Description

Technical Field

[0001] The utility model relates to an oil-drip-proof and winding-proof rotating device. Background Art

[0002] The polyester filament spinning device performs melt spinning, which requires the process of speed reducer---drive shaft-metering pump---spinning box---components---spinning and pulling to finally form fibers. However, three problems arise during the operation of the speed reducer and the drive shaft: 1. The speed reducer operates in a high-temperature environment for a long time, and the lip seal ring below it is prone to wear, causing a small amount of lubricating oil in the speed reducer to flow out to the top of the coupling and then drip onto the spinning box. Over the years, the insulation cotton on the spinning box will accumulate lubricating oil, which is very likely to spontaneously combust under the action of high temperature and long-term baking; 2. The universal joint at the lower part of the lower transmission rod is very likely to stir the insulation blanket around the outside of the transmission shaft during rotation, causing damage to the equipment above the box, and the universal joint is also very likely to stir the human body's clothes during operation, causing injuries to people, which is prone to accidents; 3. Since the transmission shaft is easily entangled with the insulation blanket around the transmission shaft, the insulation blanket is difficult to lay in place, resulting in inadequate insulation.

[0037] See also Figures 1 to 13 The anti-drip and anti-winding rotating device shown includes a reducer 3, a transmission assembly, a protective sleeve 1, and an oil receiving pan 2. The transmission assembly includes a universal coupling 4, a transmission shaft, and a universal joint 7, wherein:

[0038] The universal joint 4, the transmission shaft and the universal joint 7 are distributed in sequence, the reducer 3 is connected to the universal joint 4, the universal joint 4 is connected to one end of the transmission shaft, and the other end of the transmission shaft is rotatably connected to one end of the universal joint 7. The transmission shaft includes a universal joint spline shaft 5 and a sleeve 6 that are arranged in conjunction with each other. The sleeve 6 is sleeved on the outside of the universal joint spline rod, the universal joint spline rod is rotatably connected to the universal joint 4, the sleeve 6 is rotatably connected to the universal joint, and a bearing is provided on the sleeve 6; the universal joint 7 includes an integrally arranged rod body and a connecting section, and the connecting section is rotatably connected to the other end of the transmission shaft (sleeve 6).

[0039] The protective sleeve 1 is sleeved on the connection between the other end of the transmission shaft and one end of the universal joint 7. The protective sleeve 1 is coaxially arranged with the transmission shaft. The protective sleeve 1 includes a first sleeve body 11 and a second sleeve body 12 that are connected. The first sleeve body 11 and the second sleeve body 12 are coaxially arranged. The middle parts of the first sleeve body 11 and the second sleeve body 12 are provided with a central hole that penetrates each other. The width of the first sleeve body 11 is smaller than the width of the second sleeve body 12. The first sleeve body 11 is sleeved on the transmission shaft, and the second sleeve body 12 accommodates at least part of one end of the universal joint 7, that is, the connecting section of the universal joint 7 is at least partially accommodated in the second sleeve body 12, that is, the connecting section of the universal joint 7 can be extended. The second sleeve 12; a gap is maintained between the inner circumferential wall of the second sleeve 12 and the outer circumference of one end of the universal joint 7, so that one end of the universal joint 7 can rotate relative to the other end of the drive shaft; a flexible thermal insulation part 8 is provided below the universal coupling 4, and the thermal insulation part 8 includes an insulation blanket. A through-hole is provided on the thermal insulation part 8, and the other end of the universal joint 7 passes through the through-hole. The second sleeve 12 is at least partially located in the through-hole of the thermal insulation part 8. The advantage of this arrangement is that the connection between the drive shaft and the universal joint 7 is isolated from external materials, which plays a safety protection effect. At the same time, the isolated universal joint 7 will not stir the thermal insulation part 8, and the thermal insulation part 8 can be laid in place, and the thermal insulation effect is better.

[0040] See also Figure 5The shaft sleeve 6 includes a shaft body and a connecting end. The connecting end is arranged at the other end of the shaft body and is rotatably connected to one end of the universal joint 7. The diameter of the shaft body is smaller than the diameter of the connecting end, so that a step surface 61 is formed at the connection between the connecting end and the other end of the shaft body, and the step surface 61 is arranged parallel to the axial direction of the transmission shaft; the second sleeve body 12 of the protective sleeve 1 has an inner side surface, and the step surface 61 is arranged parallel to the inner side surface. When the protective sleeve 1 is sleeved on the connection between the other end of the transmission shaft and one end of the universal joint 7, the inner side surface and the step surface 61 are abutted.

A circular through-hole is defined in the center of each of the first and second housings 11, 12. Alternatively, in some embodiments, the diameter of the second housing 12 gradually increases from the universal coupling 4 toward the universal joint 7, which increases the volume of the interior of the second housing 12 and provides more space for rotation of one end of the universal joint 7 relative to the other end of the drive shaft.

During installation, one of the first half disc and the second half disc is first placed outside the drive shaft, and then the other is placed outside the drive shaft. The first half disc and the second half disc are then connected by fasteners 28, which facilitates the installation of the oil receiving pan 2 on the drive shaft. At the same time, when the oil in the oil receiving pan 2 is full, the oil receiving pan 2 is conveniently removed. The operation is convenient and quick, and there is no need to disassemble the drive shaft.
