Abstract
The utility model provides a motor shaft, comprising a shaft body, a first connecting body and a second connecting body, wherein the diameter of the first connecting body is less than that of the shaft body; the diameter of the shaft body is less than that of the second connecting body; the first connecting body is arranged at one side of the shaft body; the second connecting body is arranged at the other side of the shaft body; a knurl and an annular groove are arranged on the shaft body; the annular groove is arranged between the knurl and the second connecting body; a spline groove is arranged at the end part of the second connecting body; and a chamfer is arranged at the end part of the spline groove. According to the motor shaft provided by the utility model, the spline groove, instead of a conventional flat key groove, is arranged at the output end of a shaft, that is to say, the flat key connection is replaced by the spline connection, so that the connection stress is quite uniform; the strengths of the shaft and the hub are less weakened; a larger load can be born; and the motor shaft has the characteristics of good guidance, and convenience and rapidness for installation.
Description
Technical field
The utility model relates to a kind of motor shaft, particularly a kind of motor shaft with spline.
Background technique
Motor is one of equipment that is most widely used in productive life, the performance of motor shaft has a significant impact motor performance, it is the key component of motor, the structure of motor shaft mainly contains some floors and is welded on the main shaft and combines, silicon chip and coil are centered around on the floor, the electric current that utilizes magnetic field to produce comes work, general motor shaft connects other equipment such as speed reducer by flat key at output terminal, in the moment of electric motor starting, the impact force of generation all concentrates on the flat key, produces stress and concentrates, if things go on like this, make it produce fatigue crack and lost efficacy, affect its working life, harm personal safety as well as the property safety when serious; And can not carry larger torque.
The model utility content
The technical problem that (one) will solve
The technical problems to be solved in the utility model provides a kind of motor shaft that is provided with spline at output terminal.
(2) technological scheme
For solving the problems of the technologies described above, the utility model provides a kind of motor shaft, comprise axis body 1, the first connecting body 2 and the second connecting body 3, the diameter of described the first connecting body 2 is less than the diameter of described axis body 1, the diameter of described axis body 1 is less than the diameter of described the second connecting body 3, described the first connecting body 2 is positioned at described axis body 1 one sides, described the second connecting body 3 is positioned at described axis body 1 opposite side, described axis body 1 is provided with annular knurl 4 and circular groove 5, described circular groove 5 is between described annular knurl 4 and described the second connecting body 3, described the second connecting body 3 ends are provided with spline 6, and described spline 6 ends are provided with chamfering 7.
Further, described circular groove 5 is between described annular knurl 4 and described the second connecting body 3, near a side of described annular knurl 4.
Further, described the second connecting body 3 two ends are respectively equipped with the first chamfering 8 and the second chamfering 9.
(3) beneficial effect
The utility model motor shaft at the output terminal of axle, changes traditional flat key groove into spline, namely flat key is connected to change spline joint into, because at direct and well-balanced more tooth and the groove made on the axle and on the hub bore, so connect stressed more even; Because spline is more shallow, tooth root place stress is concentrated less, and the strength reduction of axle and hub is less; Because spline tooth number is more, the gross area is larger, can bear larger load; Guidance quality is better; Owing to be provided with chamfering in the spline end, make its installation more convenient, quick.
Description of drawings
Fig. 1 is the structural representation of the utility model motor shaft;
Fig. 2 is the partial sectional view of the utility model motor shaft.
Embodiment
Consult Fig. 1 ~ Fig. 2, the utility model provides the utility model that a kind of motor shaft is provided, comprise the first connecting body 2 that links to each other successively, axis body 1 and the second connecting body 3, and the first connecting body 2, the diameter of axis body 1 and the second connecting body 3 increases successively, axis body 1 is provided with annular knurl 4, annular knurl 4 can increase its skin friction, between annular knurl 4 and the second connecting body 3, near annular knurl 4 a side, be provided with a circular groove 5, this circular groove 5 is installed jump rings, play the role of positioning, in the second connecting body 3 ends, have spline 6, the end of this spline 6 is provided with chamfering 7, this chamfering 7 play the guiding role spline when inserting spline 6, make spline that more convenient and quicker is installed.At the second connecting body 3 two ends, be respectively equipped with the first chamfering 8 and the second chamfering 9, these chamferings can be removed the burr that work in-process occurs, and its leading role in installation process.
The utility model motor shaft at the output terminal of axle, changes traditional flat key groove into spline, namely flat key is connected to change spline joint into, because at direct and well-balanced more tooth and the groove made on the axle and on the hub bore, so connect stressed more even; Because spline is more shallow, tooth root place stress is concentrated less, and the strength reduction of axle and hub is less; Because spline tooth number is more, the gross area is larger, can bear larger load; Guidance quality is better; Owing to be provided with chamfering in the spline end, make its installation more convenient, quick.
The above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
