FIG. 3 is a front cross-sectional view of a plurality of components of the present invention as mounted on a shaft.

Detailed Description

The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.

As can be seen from fig. 1 to 3, the present invention includes an annular sleeve 1, an annular groove 2 is provided on the outer edge of the annular sleeve 1, an annular protrusion 3 is provided on the right side inside the annular sleeve 1, a bearing 4 is provided inside the annular sleeve 1, the bearing 4 is installed inside the annular sleeve 1 in an interference fit manner and is limited by the annular protrusion 3, and an elastic collar 5 for holes is provided on the left side of the bearing 4.

In order to realize the installation of the circlip 5 for holes, the inner edge of the annular sleeve 1 is provided with an annular installation groove, and the circlip 5 for holes is installed in the installation groove.

In order to realize the limit of a plurality of assemblies when the assemblies are installed on the shaft, a positioning retainer ring 6 sleeved on the shaft is arranged between the two adjacent assemblies.

In order to achieve the mounting on the shaft, the two components at the two ends of the shaft are mounted in opposite directions.

In order to realize the sealing between the shaft and the end part assembly, two ends of the shaft are sleeved with elastic check rings 7 for the shaft.

The specific working process of the utility model is as follows: the device is sleeved on a rotating shaft and is installed in a well, a steel wire rope can be used after bypassing an annular groove, the components are rope wheel component units, the number of the components is selected according to corresponding requirements, the components are connected in series by a shaft, the method is simple, the components are separated from one another by positioning check rings 6, and all the units do not need to rotate synchronously.

The significant benefits of the present device:

1. the way the present arrangement increases the service life of the bearings 4 is to form separate grooves each with a separate bearing 4 supporting them on the mounting shaft, which increases the number of bearings 4 and results in a reduced load per bearing 4.

2. The processing difficulty is reduced, and the processing precision, namely the concentricity of the annular groove and the hole of the bearing 4, is ensured.

3. Retrench the modularization, and bearing 4, circlip all are standard parts, and processing cost is low, and administrative cost, assembly cost are all effectively reduced.
