Abstract
The utility model relates to the technical field of motors, and in particular relates to a motor rotating shaft. The motor rotating shaft comprises a rotating shaft, and is characterized in that an iron core stop guide table, which is a conical transitional table, is arranged at the front end of an iron core stop on the rotating shaft. The motor rotating shaft is rational in design, simple in structure, easy to process, low in cost and convenient to operate and mount.
Description
Technical field
The utility model relates to the technical field of motor, specifically a kind of machine shaft.
Background technology
The empty platform that iron core shelves are all arranged in the rotating shaft of existing motor, in use, because the dimensional tolerance of rotating shaft iron core shelves front end and iron core shelves differs about 0.3mm, when cast-aluminum rotor passes rotating shaft, because iron core shelves front end and cast-aluminum rotor gap are too small, the easy torsional deformation of rotating shaft, also can pull the endoporus of rotating shaft iron core shelves and cast-aluminum rotor, reduce the qualification rate of product, its assembling speed is slow, and production efficiency is low.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiency of above-mentioned technology, and a kind of machine shaft of reasonable in design, simple in structure, easy processing is provided.
Technical solution adopted in the utility model is: a kind of machine shaft, comprise rotating shaft, and it is characterized in that the front end of rotating shaft upper core shelves is provided with iron core shelves guide table, the iron core shelves guide table of iron core shelves front end is the circular cone transition bench.
Because the cored shelves of rotating shaft iron core shelves front end guide table, the iron core shelves guide table of iron core shelves front end is the circular cone transition bench, cast-aluminum rotor is when passing rotating shaft, iron core shelves guide table plays the correcting effect, has axiality when making the assembling of iron core shelves and cast-aluminum rotor, cast-aluminum rotor can be contained on the rotating shaft iron core shelves accurately and rapidly, has improved quality and the production efficiency of product.The utility model processing reasonable in design, simple in structure, easy, cost are low, operation, easy for installation.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is assembling schematic diagram of the present utility model.
Mark among the figure: 1. rotating shaft, 2. iron core shelves guide table, 3. iron core shelves, 4. cast-aluminum rotor.
Embodiment
As shown in Figure 1, a kind of machine shaft comprises rotating shaft 1, is provided with iron core shelves guide table 2 at the front end of rotating shaft upper core shelves 3, and the iron core shelves guide table 2 of iron core shelves 3 front ends is the circular cone transition bench.Cast-aluminum rotor 4 passes rotating shaft 1 and is contained on the iron core shelves 3, cast-aluminum rotor 4 is when passing rotating shaft, iron core shelves guide table 2 plays the correcting effect, axiality when having guaranteed iron core shelves 3 and cast-aluminum rotor 4 assembling, cast-aluminum rotor 4 is contained in the rotating shaft 1 accurately and rapidly, improve the qualification rate of assembling rotating shaft 1 and cast-aluminum rotor 4, also improved operator's operating efficiency simultaneously.
Claims (1)
