Problems solved by technology

Among them, the grease-lubricated coupling has been widely used in rail subways, high-speed rail and other fields. The structure of the grease-lubricated coupling generally includes an inner gear cylinder, an outer gear hub, a thrust ring, an end cover and a sealing ring, etc. Components, since the grease lubricated coupling is smeared with butter between the inner gear cylinder and the outer gear hub for lubrication, although its sealing performance is not as high as that of the oil lubricated coupling, but it is in the process of manufacturing, There are also high technical requirements for assembly and later maintenance and testing.
[0003] At present, there is no standard and standardized maintenance process for the maintenance and inspection of grease-lubricated couplings in the later stage, which makes the operations of grease-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 lead to the failure of the most scientific and effective maintenance and testing of grease-lubricated couplings during the maintenance process. Often, parts that can continue to be used are replaced, and parts that are not yet serviceable are replaced. , There are many wrong ways to continue to use parts that need to be replaced

Embodiment 1

[0055] A maintenance method for a grease-lubricated shaft coupling, using the maintenance method to detect and maintain an ESCO shaft coupling, the steps are as follows:

[0056] (1) Registration at the factory: take photos and register the ESCO half-couplings to be repaired and tested, and record the number and mark of the half-couplings to prevent confusion;

[0057] (2) Disassembly: Remove the components on the ESCO half coupling, first remove the end cover bolts and end cover bolt washers, then remove the end cover, and then remove the end cover together with the outer gear hub from the inner gear cylinder, Then remove the spring retaining ring from the outer gear hub, then pull out the outer gear hub from the end cover, remove the thrust washer and thrust ring, and finally remove the O-ring from the outer gear hub;

[0058] Perform the same inspection on the inner gear cylinder, outer gear hub, end cover, thrust ring, thrust washer, gasket, energy storage sealing ring, an...

Embodiment 2

[0082] A maintenance method using a grease-lubricated coupling to detect and maintain ESCO couplings, the maintenance steps are as described in Example 1, the difference is that the energy storage sealing ring is ring-sleeved on the outer gear hub by using a press-fitting tool Above, wherein, the pressing tool includes an inner sleeve and an outer sleeve nested inside and outside, the inner sleeve includes a conical upper part and a lower cylindrical body connected as one, and a stepped hollow is arranged in the inner sleeve. The upper end of the circular frustum has a through hole connecting the cavity; the outer sleeve is a hollow cylinder, and three long slits are evenly distributed on the side wall of the hollow cylinder, and the top of the long slit is provided with Arc. The specific structure of the pressing tool is as follows: Figure 2a to Figure 4 shown.

[0083] When in use, the "lip" of the energy storage sealing ring faces upward, so that the stepped cavity of th...

Abstract

The invention relates to a maintenance method for grease lubrication type couplers. The maintenance method at least comprises the steps of preliminary washing, disassembling, cleaning, detecting and assembling. According to the invention, 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 of 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 saved. 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 grease 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 a grease 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 grease-lubricated coupling has been widely used in rail subways, high-speed rail and other fields. The structure of the grease-lubricated coupling generally includes an inner gear cylinder, an outer gear hub, a thrust ring, an end cover and a sealing ring, etc. Components, since the grease lubricated coupling is smeared with butter between the inner gear cylinder and the outer gear hub for lubrication, although its sealing performance is not as high as that of the oil lubricated coupling, but it is in the process of manufacturing, There are also high technical requirements for assembly and later maintenance and testing. [0003] At present, there is no sta...
