Abstract
The utility model discloses a direct current motor output shaft. The direct current motor output shaft comprises a shaft body and a gear frame connected with one end of the shaft body, wherein the shaft body is connected with the gear frame in a riveting mode. Compared with an original direct current motor output shaft, the direct current motor output shaft has the advantages that the shaft body and the gear frame are machined separately and are connected together in the riveting mode in the process of assembling, the shaft diameter change of the shaft body is small, the machining allowance is small, and therefore the shaft body can be formed in a machining mode, production efficiency is high, and cost is low; the gear frame is manufactured through powder metallurgy, and therefore the precision of the manufactured gear frame is higher than that of a gear frame formed in an original machining mode, production efficiency is high, and cost is low; the structural strength of the direct current motor output shaft with the shaft body and the gear frame being connected in the riveting mode is not lower than that of an integrally formed direct current motor output shaft; when damaged, the shaft body or the gear frame can be replaced accordingly, and maintaining cost is saved.
Description
Technical field
The utility model relates to a kind of output shaft of direct current generator.
Background technique
Output shaft on direct current generator generally adopts one processing mode now, axis body 1 and gear carrier 2 as a whole (as shown in Figure 2), because the diameter of axis body 1 and gear carrier 2 differs larger, cause bite larger, waste material on the one hand, processing cost is higher on the other hand.
Model utility content
The utility model technical issues that need to address are, a kind of easy to process, cost-saving, direct current generator output shaft that precision is higher is provided.
The technical solution of the utility model is: a kind of direct current generator output shaft, comprise axis body, and with the gear carrier that axis body one end is connected, described axis body and gear carrier riveted joint are integrated.
As preferably, described gear carrier is patty, and gear carrier center is provided with polygonal hole, and described axis body and gear carrier connecting end are provided with polygon end head, and described polygon end head and polygonal hole are by pressure riveting structure interference fit.
As preferably, the cross-sectional profiles line of described polygonal hole and polygon end head comprises two parallel straightways and connects the circular arc line of two straightways.
As preferably, described gear carrier is powder metallurgy forming structure.
As preferably, described gear carrier and axis body connecting end surface are provided with the annular groove of sinking around described polygonal hole.
As preferably, described gear carrier is evenly equipped with mounting hole around described polygonal hole.
As preferably, described axis body is multidiameter shaft structure.
Compare with direct current generator output shaft in the past, the utility model is by axis body and gear carrier separate machined, and the mode with riveted joint when assembling is connected, axis body is less because the diameter of axle changes, and machining allowance is less, adopts machining plastic, manufacturing efficiency is high, and cost is low; Gear carrier adopts powder metallurgy manufacture, and the gear carrier precision of produced like this gear carrier machining moulding is more in the past high, and manufacturing efficiency is high, cost is low; And there are axis body, gear carrier to rivet the direct current generator output shaft of the not defeated one machine shaping of structural strength of the direct current generator output shaft being connected; When axis body or gear carrier are destroyed, more can change targetedly, saved maintenance cost.
Accompanying drawing explanation
Accompanying drawing 3 is the whole-cutaway view of overlooking after gear carrier coordinates with axis body;
Accompanying drawing 4 is overlooked whole-cutaway view after coordinating for the gear carrier of another kind of form and the axis body that matches with it.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Figures 1 to 4, the direct current generator output shaft of the present embodiment, a direct current generator output shaft, comprises axis body 1, the gear carrier 2 being connected with axis body 1 one end, axis body 1 is integrated with gear carrier 2 riveted joint when assembling, axis body 1 is less because the diameter of axle changes, and machining allowance is less, adopts machining plastic, manufacturing efficiency is high, and cost is low; Gear carrier 2 adopts powder metallurgy manufacture, and gear carrier 2 precision of produced like this gear carrier 2 machining moulding are more in the past high, and manufacturing efficiency is high, cost is low; Gear carrier 2 is patty, and gear carrier 2 centers are provided with polygonal hole 21, and polygonal hole 21 has various deformation, and generally the profile line of its cross section is by circular arc line and rectilinear(-al), such as " D " font etc.Described axis body 1 is provided with polygon end head 10 with gear carrier 2 connecting ends.The cross-sectional profiles line of polygonal hole 21 and polygon end head 10 comprises two parallel straightways and connects the circular arc line of two straightways; Gear carrier 2 is provided with the annular groove 22 of sinking with axis body 1 connecting end surface around described polygonal hole 21, described axis body 1 is multidiameter shaft structure, bevel edge near polygon end head 10 places on annular groove 22 and axis body 1 cooperatively interacts, and has certain leading role when axis body 1 assembles with gear carrier 2; Described gear carrier 2 is evenly equipped with mounting hole 20 around described polygonal hole 21.When axis body 1 and gear carrier 2 are in use destroyed, can have more actual conditions and selectively change, and needn't as in the past, must discard whole direct current generator output shaft, saved the cost of later maintenance.
Below only with regard to the utility model preferably example be described, but can not be interpreted as it is limitations on claims.The utility model not only limits to and above example, its concrete structure those skilled in the art that allow to change can make various changes and distortion according to the utility model, only otherwise depart from spirit of the present utility model, all should belong to the defined scope of the utility model claims.
