Abstract
The utility model relates to a coupling for transmitting rotation, particularly a telescopic cross axial twin universal shaft coupling provided with an intermediate axle, comprising a flat key, a flanged yoke head, a cross axle assembly, a welding spline slip yoke and a steel pipe. The utility model is characterized in that the intermediate axle is changed into involute spline draw bail from the original rectangle spline draw bail. Compared with the original rectangle spline, the utility model has the advantages of anti-squeeze, triple wear-resistance increasing, 20% strength increasing, and easy centering.
Description
The utility model relates to a kind of coupling of conveying rotary motion, especially is provided with the telescopic Cardon universal joint double universal coupling of jack shaft.
At present, be applied to the telescopic Cardon universal joint double universal coupling of rolling mill, arbor press, finishing cold bed, lifting, mine transportation and other heavy machinery, its jack shaft adopts rectangular spline always, its deficiency is: 1, the rectangle number of teeth of rectangular spline is few, the regulation number N of teeth is 6,8,10 in the NBS, cause it to connect unbalance stress, the moment of torsion bearing capacity is poor, cause key axle torsional deformation even fracture: 2, profile of tooth is the flat key shape, stress is concentrated, a little less than the anti-extrusion ability, footpath, tooth root garden is little, causes frequent broken teeth; 3, adopt the centering of big footpath usually, steering capability is poor, and is easy to wear, is difficult for centering.In using at the scene if one of above-mentioned deficiency takes place, replacings that promptly will stop production, this is concerning production line production, the loss of stopping production is very serious.
The purpose of this utility model proposes a kind of involute splines that adopts and replaces the Cardon universal joint double universal coupling of original rectangular spline as jack shaft for overcoming above-mentioned deficiency.
In telescopic Cardon universal joint double universal coupling, replace original rectangular spline with involute splines, have the following advantages: 1. the involute splines number of teeth can make choosing by the 10-100 tooth, modulus is optional, under same length, diameter, material condition, its anti-crowded, wear-resistant calculating according to formula can be improved three times; 2. the root diameter of involute splines is bigger than rectangular spline, and its intensity is calculated according to formula can improve 20%; 3. the involute splines matching surface is to connect secondary all tooth flank surface, has both played gearing, but self-alignment again, axial stretching freely, easy centering.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
As shown in the figure, the two universal shaft couplings of the utility model embodiment's Cardon universal joint comprise flat key (1), flange jaw (2), cross axle assembly parts (3), welding spline slip yoke (4), steel pipe (5); Involute splines cover (6) one ends and the welding of steel pipe (5) end face, involute splined shaft (7) one ends and the welding of welding spline slip yoke (4) end face.
Claims (1)
1, a kind of Cardon universal joint double universal coupling comprises flat key, flange jaw, cross axle assembly parts, welding spline slip yoke, steel pipe, it is characterized in that changing jack shaft into the involute splines connecting structure by original rectangular spline connecting structure.
