Abstract
The utility model belongs to the technical field of power transmission, and relates to an output shaft for a speed reducer. The output shaft for the speed reducer comprises an output shaft body; a positioning hole is formed in the end surface of the front part of the output shaft body; the tail part of the output shaft body is a connecting seat; a plurality of connecting holes are uniformly distributed in the connecting seat; a key groove is milled in the outer circumferential surface on the front part of the output shaft body; a groove used for discharging scraps is also formed in the output shaft body; the groove is formed in the joint between the shaft part and the connecting seat of the output shaft body. Through technical improvement, the connecting seat of the output shaft and the shaft part of the output shaft of the speed reducer in the prior art are connected with each other through a conical transition surface, and the groove is formed in the joint of the connecting seat and the shaft part, so that stress concentration is eliminated effectively, meanwhile, the scraps can be discharged through the groove; therefore, the shaft is prevented from wearing; in addition, the joint between the output shaft and the speed reducer can be lubricated effectively through an oil injection hole formed in the connecting seat.
Description
Technical field
The utility model belongs to power transmission technical field, relates to a kind of speed reducer output shaft.
Background technique
Output shaft is indispensable important component part in speed reducer, and its service behaviour and quality good or not directly affect service behaviour and the reliability of speed reducer.
Existing speed reducer output shaft structure is conventionally comparatively simple, often just in optical axis one end, mill out connection keyway, the other end is connecting base, be used for being fixed on speed reducer output terminal, the output shaft of this structure and speed reducer output terminal joint lack lubricating fitting, cause output shaft joint easily to be worn and torn and affect output effect; In addition, output shaft axial region lacks transition with being connected of connecting base, easily causes stress to concentrate.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of speed reducer output shaft simple in structure, ingenious, rational is provided, and this output shaft can carry out effectively lubricating to joint, and can effectively avoid stress to concentrate.
The technological scheme providing according to the utility model: a kind of speed reducer output shaft, be characterised in that: comprise output shaft body, described output shaft body portion end face is provided with positioning hole, output shaft body afterbody is connecting base, uniform on described connecting base some attachment holes are set, on output shaft body portion outer peripheral surface, milling has keyway, be also provided with the groove for chip removal, and groove is arranged at the joint of output shaft body axial region and connecting base on described output shaft body.
As further improvement of the utility model, between output shaft body axial region and connecting base, by the transition of tapering transition face, be connected.
As further improvement of the utility model, at described tapering transition face, offer oil hole, the internal cavities of connecting base is connected in oil hole lower end.
The utility model compared with prior art, advantage is: the utility model is by technological improvement, the connecting base of speed reducer output shaft of the prior art is connected by tapering transition face with output shaft axial region, Bing joint arranges groove, effectively eliminate stress concentrated in, also can pass through groove chip removal, can not cause the wearing and tearing of axle; Can also to output shaft and speed reducer joint, carry out effectively lubricating by the oil hole arranging on connecting base in addition.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, comprise positioning hole 1, keyway 2, connecting base 3, attachment hole 4, output shaft body 5, groove 6, oil hole 7 etc.
As shown in Figure 1, a kind of speed reducer output shaft, comprise output shaft body 5, described output shaft body 5 front end face are provided with positioning hole 1, output shaft body 5 afterbodys are connecting base 3, uniform on described connecting base 3 some attachment holes 4 are set, and on the anterior outer peripheral surface of output shaft body 5, milling has keyway 2, on described output shaft body 5, be also provided with the groove 6 for chip removal, and groove 6 is arranged at the joint of output shaft body 5 axial regions and connecting base 3.
Between output shaft body 5 axial regions and connecting base 3, by the transition of tapering transition face, be connected.
At described tapering transition face, offer oil hole 7, the internal cavities of connecting base 3 is connected in oil hole 7 lower ends.
The utility model working procedure is as follows: by output shaft body 5 by attachment hole 4 and bolton in speed reducer output terminal, when speed reducer work, output shaft body 5, under speed reducer drives, rotates, and realizes the object that braking maneuver mechanical compliance profit is exported.
The utility model is by technological improvement, the connecting base of speed reducer output shaft of the prior art is connected to ，Bing joint with output shaft axial region by tapering transition face groove is set, effectively eliminate stress concentrated in, also can pass through groove chip removal, can not cause the wearing and tearing of axle; Can also to output shaft and speed reducer joint, carry out effectively lubricating by the oil hole arranging on connecting base in addition.
