Abstract
The utility model relates to an output shaft adapter sleeve which is reasonable in structural design and high in fastness. The output shaft adapter sleeve comprises a sleeve body with the outer diameter of 44 mm. An internal spline with the outer diameter of 30 mm and the inner diameter of 25.5 mm is arranged inside the sleeve body and provided with 13 teeth. A projection with the width of 4 mm and the diameter of 52 mm is arranged at one end of the sleeve body; the distance between the outer side of the projection and the side wall of the sleeve body is 1 mm; the diameter of the part of the sleeve body within the width of 1 mm is 38 mm. A groove with the diameter of 45 mm and the width of 1.3 mm is arranged at the joint between the other side of the projection and the sleeve body. The groove and the projection are in transition through a fillet with the radius of 0.5 mm, the groove and the sleeve body are connected through a 60-degree bevel, and the diameter of the side part, connected with the groove, with the width of 13.7 mm, of the sleeve body is 45 mm. The output shaft adapter sleeve is used with an electric hoister; through reasonable structural design, the connection fastness of the adapter sleeve can be improved effectively and the adapter sleeve can bear higher torque; the internal spline arranged inside the sleeve body fits with an external spline of an output shaft so that torque transmission is realized.
Description
Technical field
The utility model relates to crane gear field, especially a kind of for the output shaft connecting sleeve 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 connecting sleeve 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, the output shaft connecting sleeve that fastness is large in order to solve the deficiency of above-mentioned technology.
In order to achieve the above object, the output shaft connecting sleeve that the utility model is designed, assembly is 35mm, it comprises body, the external diameter of body is 44mm, body inner hollow, and the inside of body is provided with internal spline, the external diameter of internal spline is 30mm, and the internal diameter of internal spline is 25.5mm, and the number of teeth is 13; In one end of body, being provided with width is the projection that 4mm, diameter are 52mm, the distance of the outside of projection and the cover body sidewall of this end is 1mm, and the diameter of the body in this 1mm width is 38mm, in the joint of protruding opposite side and body, being provided with diameter is the groove that 45mm, width are 1.3mm, the round-corner transition that is 0.5mm by radius between groove and projection, inclined-plane by 60 ° between groove and body is connected, and the diameter of the body that the side being connected with groove, width are 13.7mm is 45mm.
The resulting output shaft connecting sleeve of the utility model, it is for electric wire hoist, and it is by rational structural design, can effectively improve the connection fastness of connecting sleeve, can bear larger torsion, and the inner internal spline arranging coordinates with the external splines of output shaft, realize the transmission of torsion.
