Abstract
The utility model provides a shaft sleeve. The utility model relates to a shaft sleeve especially relates to the improvement of shaft sleeve for the generator. A shaft sleeve is provided which is fixed in assembly position and does not require frequent adjustment. The shaft sleeve comprises a body, wherein a positioning hole is formed in the body, the shaft sleeve comprises an inserting portion and a limiting portion, the diameter of the inserting portion is larger than that of the limiting portion and is communicated with the limiting portion, a slope is arranged between the inserting portion and the limiting portion, a shaft enters the limiting portion from the inserting portion, and a table top on the shaft is matched with the slope. When the axle inserts, epaxial mesa butt is on domatic, and domatic plays limiting displacement, when the installation targets in place, realizes spacingly through mesa, domatic butt, avoids the axle to install not to the position and need adjust repeatedly, influences the installation progress.
Description
Technical Field
The utility model relates to a shaft sleeve especially relates to the improvement of shaft sleeve for the generator.
Background
The existing generator shaft sleeve is generally a straight sleeve and is directly sleeved on a shaft, the shaft sleeve is easily slid after being sleeved on the shaft and is not well positioned during assembly, so that the mounting position of the shaft sleeve needs to be frequently adjusted, and the assembly efficiency is influenced.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model provides a shaft sleeve with fixed assembly position and no need of frequent adjustment.
The utility model discloses a following technical scheme realizes: the shaft sleeve comprises a body, wherein a positioning hole is formed in the body, the shaft sleeve comprises an inserting portion and a limiting portion, the diameter of the inserting portion is larger than that of the limiting portion and is communicated with the limiting portion, a slope surface is arranged between the inserting portion and the limiting portion, a shaft enters the limiting portion from the inserting portion, and a table top on the shaft is matched with the slope surface.
The slope surface is arranged on the inner wall of the limiting part, transition surfaces are arranged on the outer walls of the inserting part and the limiting part, and the transition surfaces are vertical surfaces.
The limiting part is inserted into the insertion part, and the inner wall of the insertion part is attached to the outer wall of the limiting part.
Compared with the prior art, the utility model discloses when the assembly, domatic limiting displacement that has played, when the axis is inserted, epaxial mesa butt is domatic, domatic limiting displacement that plays, when the installation targets in place, realizes spacingly through mesa, domatic butt, avoids the axle to install not to the position and need adjust repeatedly, influences the installation progress.
Drawings
FIG. 1 is a schematic structural view of the present invention;
in the figure: 1. an insertion portion; 2. a limiting part; 3. a slope surface; 4. a transition surface; 5. and (7) positioning the holes.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.
As shown in fig. 1, the shaft sleeve comprises a body, a positioning hole 5 is arranged on the body, the shaft sleeve comprises an insertion part 1 and a limiting part 2, the diameter of the insertion part 1 is larger than that of the limiting part 2 and is communicated with the limiting part 2, a slope 3 is arranged between the insertion part 1 and the limiting part 2, a shaft enters the limiting part 2 from the insertion part 1, and a table surface on the shaft is matched with the slope 3. Like this when the assembly, domatic 3 has played limiting displacement, and when the axle inserts, epaxial mesa butt is on domatic 3, and domatic 3 plays limiting displacement, when the installation targets in place, realizes spacingly through mesa, domatic 3's butt, avoids the axle to install out-of-position needs to adjust repeatedly, influences the installation progress.
The slope surface 3 is arranged on the inner wall of the limiting part 2, the outer walls of the insertion part 1 and the limiting part 2 are provided with transition surfaces 4, and the transition surfaces 4 are vertical surfaces. The limiting part 2 is inserted into the insertion part 1, and the inner wall of the insertion part 1 is attached to the outer wall of the limiting part 2. When the assembly, domatic 3 has played limiting displacement, when the axle inserts, epaxial mesa butt is on domatic 3, and domatic 3 plays limiting displacement, when the installation targets in place, realizes spacingly through mesa, domatic 3's butt, avoids the axle installation not in place to need to adjust repeatedly, influences the installation progress.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
Claims (3)
