[0009] Figure 1 is the schematic diagram of the three-dimensional structure of the long shaft type motor shaft.

[0010] In the diagram, 1 is the main spindle body; 2 is the mounting sleeve; 3 is the connecting flange; 4 is the reinforcing rib; 5 is the sealing ring; and 6 is the protrusion. Detailed Implementation

[0011] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0012] like Figure 1 As shown, this long-shaft motor shaft includes a main shaft body 1. A wear-resistant component is fitted onto the main shaft body 1 and is movably connected to it to reduce runout wear. This wear-resistant component includes a movable unit connected to the main shaft body 1 for easy rotation, and a mounting unit for connecting to other structures (such as connecting rods, connecting plates, etc.) or equipment and for mounting the movable unit to reduce runout wear. The mounting unit includes a mounting sleeve 2. A connecting flange 3 is provided on the outer peripheral wall of the mounting sleeve 2 for easy connection to other structures or equipment. Several reinforcing ribs 4 are provided between the connecting flange 3 and the mounting sleeve 2 to enhance the connection strength. The reinforcing ribs 4 may have weight-reducing holes or threaded holes. The movable unit includes two movable bearings, both of which are fitted onto and connected to the main shaft body 1. The inner wall of the mounting sleeve 2 at both ends has corresponding movable bearings. The mounting groove for the movable bearing is provided. The main shaft body 1 has a stepped groove for the movable bearing to be installed. The two ends of the mounting sleeve 2 are provided with sealing rings 5 ​​that are connected to and seal the main shaft body 1. A sealing ring is provided between the sealing ring 5 and the main shaft body 1. The mounting sleeve 2 is also fitted onto the main shaft body 1 with a gap between it and the movable bearing. The outer peripheral wall of the mounting sleeve 2 is provided with a connecting hole that connects the inside and outside of the mounting sleeve 2. The outer peripheral wall of the mounting sleeve 2 at the connecting hole is provided with an axially outward protruding and hollow protrusion 6. A sealing cover is provided on the protrusion 6 and connected to it. Lubricating oil can be injected into the mounting sleeve 2 through the sealing cover. Two symmetrically arranged guide rings are fitted on the outer peripheral wall of the main shaft body 1 at the mounting sleeve 2. The two guide rings are located on the two movable bearing assemblies and the outer peripheral walls of the two guide rings are inclined.

[0013] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0014] Although the terms main shaft body 1, mounting shell 2, connecting flange 3, reinforcing rib 4, sealing ring 5, protruding part 6 are used more in this text, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the utility model; it is contrary to the spirit of the utility model to interpret them as any kind of additional limitation.
