Embodiment 1

[0034] The technology of the present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods.

[0035] 1) The first step is to make the rubber gasket (on figure 1 8) It is installed at a circle of fastening bolts on the side of the oil bag protective cover 6 to prevent the lubricating oil from leaking out from here after the follow-up sealing is completed;

[0036] 2) The second step, on figure 1 Use cleaning agent to clean the circumference of the transmission shaft at positions 9 and 10 in the figure;

[0037] 3) In the third step, wrap and fix the shaft in the circumferential direction with a sticky PTFE sealing tape 11 (width: 5mm; thickness: 1mm) at the positions 9 and 10 shown in the figure above, and wrap 2 on each side. Circle, and ensure that the interface 12 intersects (60° cut at the interface), a closed circle of circumferential size and shape can be formed. The 2-turn PTFE sealing tape interfac...

Abstract

The invention provides a rapid plugging method used for an oil pocket for lubricating a crown gear transmission shaft. The oil pocket is an oil pocket used for lubricating the transmission shaft, and a barrel-shaped oil pocket protective cover is arranged at the periphery of the oil pocket. The rapid plugging method is characterized by comprising the following steps: (1) installing a rubber gasket at a fastening bolt on the side surface of the oil pocket protective cover to prevent lubricating oil from leaking from the part after plugging; (2) cleaning the transmission shaft along the circumferential direction of the transmission shaft by using a detergent; (3) taking a sealing tape with a single side being adhesive, winding the sealing tape on the circumferential surface (9) of the oil pocket protective cover and the circumferential surface (10) of a flat head sleeve along the circumferential direction of the transmission shaft to form a closed ring at the parts; (4) winding and bonding a rubber sheet with the middle provided with a reinforcing material on the sealing tape, and overlapping interfaces of the rubber sheet. The field application effect is good, and the promotion prospect is good.

Description

technical field [0001] The invention belongs to the technology of metallurgical machinery / cold rolling machinery, relates to a fast plugging technology, in particular to a fast plugging method for oil bag leakage in a high-speed rotating state. In particular, the present invention relates to a method for quickly plugging the oil bag (Boots) used for lubricating the crown gear transmission shaft of a cold rolling mill under high-speed rotation. Background technique [0002] Crown gear drive shafts are common equipment in cold rolling mills, especially in the application of main drive shafts, and crown gears are lubricated by using oil bags (Boots) to contain lubricating oil, and then provide lubrication to the drive shaft . [0003] Since the transmission shaft is in a high-speed rotation state during operation, and needs to have a certain swing angle and expansion and contraction, it is necessary to use a rubber synthetic material with excellent extensibility and sealing pe...
