Abstract
The utility model relates to an output shaft which is reasonable in design and high in fastness and can be used in an electric hoist. The output shaft comprises a shaft body, the diameter of the shaft body is 23 mm, a shaft head is disposed at the front end of the shaft body, and a tool withdrawal groove with a width of 1 mm and an inner diameter of 16.8 mm is arranged at the joint of the shaft head and the shaft body. A first male spline with a length of 58 mm is arranged at the front end of the shaft body, and the effective facewidth of the first male spline is 40 mm. An oil seal shaft and a shaft tail are disposed at the rear end of the shaft body, the oil seal shaft is disposed between the shaft body and the shaft tail, the diameter of the oil seal shaft is 25 mm, the length of the oil seal shaft is 18.5 mm, and the length of the shaft tail is 15.5 mm. A second male spline is arranged on the shaft tail, and the effective facewidth of the second male spline is 14 mm. According to the output shaft, due to the facts that the first male spline and the second first male spline are reasonably arranged, arc chamfers are arranged at the joint between the male splines and the oil seal shaft and between the shaft body and the oil seal shaft, and the chamfered angle and length are reasonably designed in a matching mode so that the fastness of the output shaft can be effectively improved, using performance can be enhanced, service life can be prolonged, and meanwhile abrasion of the male splines can be reduced.
Description
Technical field
The utility model relates to crane gear field, especially a kind of for the output shaft on electric wire hoist.
Background technique
Existing electric hoist crane is comprised of motor, retarder, travelling mechanism, break, control switch, reel, in practice process, output shaft on electric wire hoist is bearing larger torsion and pulling force, in use easily there is the phenomenons such as fracture or spline wearing and tearing, cause the working life of electric wire hoist short, also exist the potential safety hazard of production.
Model utility content
The purpose of this utility model is to provide a kind of reasonable in design in order to solve the deficiency of above-mentioned technology, fastness large for the output shaft on electric wire hoist.
In order to achieve the above object, the output shaft that the utility model is designed, overall length is 244mm, it comprises axis body, the diameter of axis body is 23mm, front end at axis body is provided with spindle nose, and the length of spindle nose is 13mm, and the diameter of spindle nose is 17mm, it is the tool withdrawal groove that 1mm, inside diameter are 16.8mm that spindle nose and axis body joint are provided with width, front end at axis body is provided with the first external splines that length is 58mm, and effective tooth length of the first external splines is 40mm, and the external diameter of the first external splines is 21.9mm; In the rear end of axis body, be provided with oil seal shaft and axle tail, oil seal shaft is arranged between axis body and axle tail, the diameter of oil seal shaft is 25mm, and the length of oil seal shaft is 18.5mm, and the length of axle tail is 15.5mm, on axle tail, be provided with the second external splines, the length of the second external splines is 15mm, and effective tooth length of the second external splines is 14mm, and the number of teeth of the second external splines is 13, the external diameter of the second external splines is 29.5mm, and internal diameter is 24.2mm.
As optimization, the first external splines and axis body joint are by arc transition, and radius of arc is 27mm, and the axial length of transitional surface is 8mm.
As optimization, between oil seal shaft and axle tail, by arc transition, radius of arc is 3.48mm, and the axial length of transitional surface is 1mm.
As optimization, at spindle nose He Zhouwei center, be respectively equipped with an axial screw.
The resulting output shaft of the utility model, for electric wire hoist, it is by the reasonable setting of the first external splines and the second external splines, and external splines and axis body and oil seal shaft joint are equipped with circular arc chamfering, and the angle pouring into and the cooperation of length, can effectively improve the fastness of output shaft, improve usability and the working life of output shaft, can reduce the wearing and tearing of external splines simultaneously.
