A maintenance method for oil-lubricated shaft coupling

An oil-lubricated coupling technology, which is applied in the direction of couplings, elastic couplings, mechanical equipment, etc., can solve the problem that the oil-lubricated coupling cannot be maintained and inspected, and the operation of the oil-lubricated coupling is not correct. Problems such as standardization and spare parts that have not reached their service life have achieved the effect of improving the post-maintenance market, saving learning costs, and reducing waste of resources

Problems solved by technology

[0003] At present, there is no standard and standardized maintenance process for the maintenance and inspection of oil-lubricated couplings in the later stage, which makes the operations of oil-lubricated couplings in the later maintenance and inspection process irregular, the detection methods are not uniform, and the maintenance process is inconsistent. Scientific problems, which in turn caused the oil-lubricated couplings to fail to receive the most scientific and effective maintenance and testing during the maintenance process. Often, parts that could continue to be used were replaced, and parts that had not yet reached their service life were replaced. Many wrong practices that continue to use parts that need to be replaced

Embodiment 1

[0055] This embodiment provides a maintenance method using oil-lubricated couplings for inspection and maintenance of KWD170 couplings. A KWD170 coupling has been split into two half-couplings before entering the factory for inspection and maintenance. The customer will After the coupling is removed from the main shaft end of the motor, remove the twisted hole bolts of the coupling, split the whole (one) coupling into two half-couplings, and finally send the two half-couplings to the factory for maintenance .

[0056] After the half coupling enters the factory, its inspection and maintenance process is as follows:

[0057] (1) Registration at the factory: take photos and register the semi-couplings to be repaired and tested;

[0058] (2) Preliminary cleaning: Put the half coupling into SD-400 industrial degreasing cleaning agent, soak it at 25°C for 2 hours, then clean the coupling, and dry the coupling with a high-pressure air gun after cleaning;

[0059] (3) Information re...

Embodiment 2

[0112] This embodiment provides a maintenance method using an oil-lubricated coupling to detect and maintain the KWD170 coupling. stick like Figure 4 As shown, the crowbar is a long rod with an arc-shaped sharp hook at one end of the long rod. When removing the stop ring, use the arc-shaped sharp hook at the front end of the crowbar to insert into the gap around the stop ring. stick and use the ring pliers to slightly lift the stop ring with the help of the hole, such as image 3 shown.

Embodiment 3

[0114] This embodiment provides a maintenance method using an oil-lubricated coupling to detect and maintain the KWD170 coupling. The maintenance steps are as described in Example 1, and the difference is that in step (6), bellows are used for cleaning The roller cleans the bellows, and the structure of the bellows cleaning roller is as follows: Figure 8 As shown, the bellows cleaning roller includes an L-shaped rod, and an S-shaped corrugated rod is arranged at one end of the L-shaped rod. When in use, the S-shaped corrugated rod is covered with gauze and inserted into the gap of the corrugated pipe, and the worker holds the L-shaped rod to wipe the oil in the corrugated pipe back and forth.

Abstract

The invention relates to a maintenance method for oil lubrication type couplers. The maintenance method at least comprises the steps of preliminary washing, pressurization detecting, disassembling, cleaning, detecting, assembling and air tightness detecting. According to the maintenance method, a series of maintenance detection procedures and special tools are adopted, and therefore the maintenance procedures of the couplers are more scientific and reasonable, operation by maintenance detection personnel in the later stage is easy, the maintenance time is greatly shortened, the maintenance efficiency is improved, and resource waste caused by nonstandard maintenance operation in the maintenance process is reduced. Meanwhile, the maintenance detection personnel can learn the maintenance method conveniently and can master the essentials in a short time, and the learning cost of the maintenance detection personnel is reduced. Compared with existing later-stage maintenance methods, the maintenance method has the advantages that the operation procedures are more scientific and more standard, the later-stage maintenance market of the oil lubrication type couplers is expanded, the detection maintenance result is more accurate, and waste caused by inaccurate detection maintenance results is reduced to the maximum degree.

Description

technical field [0001] The invention relates to a maintenance method for an oil-lubricated shaft coupling, which belongs to the technical field of shaft couplings. Background technique [0002] According to the degree of sealing, the gear coupling has two forms of oil lubrication and grease lubrication. Among them, the oil-lubricated coupling has been widely used in rail subways, high-speed rail and other fields. The oil-lubricated coupling has a high degree of sealing and has strict technical requirements for the air tightness inside the coupling. Couplings generally include internal gear cylinders, external gear hubs, bellows, locking rings, stop rings, center plates and sealing rings in structure. Since oil-lubricated couplings have high requirements for sealing, in Its processing and manufacturing, assembly process and later maintenance and testing also have high technical requirements. [0003] At present, there is no standard and standardized maintenance process for ...
