Detailed Description

Examples

Referring to fig. 1 to 5, the present embodiment provides a spline assembly apparatus with convenient positioning, which includes a spline rod 1 and a spline housing 21 matched with the spline rod 1; the spline rod 1 is provided with an outer spline tooth structure 11 with a plurality of spline teeth, and at least one positioning tooth 12 with a key width larger than that of other spline teeth is arranged in the outer spline tooth structure 11; the spline housing 21 is provided with an internal spline structure 211 suitable for being matched with the external spline structure, the internal spline structure 211 is provided with a notch 212, and the width of the notch 212 is matched with the width of the positioning teeth 12. In the present embodiment, the spline housing 21 can be fitted into the spline shaft 1 only when the notches 212 are aligned with the positioning teeth 12, and this arrangement can prevent the mounting angle from being incorrect.

With continued reference to fig. 1 to 5, in the present embodiment, the spline rod 1 is provided with an external spline structure 11, and the external spline structure 11 includes a plurality of spline teeth uniformly arranged around the circumference of the axis of the spline rod 1, where the number of the spline teeth may be at least 4. The spline housing 21 is used for being sleeved on the spline rod 1 and is provided with an inner spline tooth structure 211 for being matched with the outer spline tooth structure 11, wherein the number and size of the spline teeth of the inner spline tooth structure 211 are set according to the outer spline tooth structure 11, so that the inner spline tooth structure 211 can be tightly matched with the outer spline tooth structure 11. Be provided with the location tooth 12 that at least one key width is greater than other flower teeth in outer flower tooth structure 11, be provided with a breach 212 on interior flower tooth structure 211, breach 212 width is greater than the clearance between other flower teeth, and the same with the width of location tooth 12, according to this setting, the key width of location tooth 12 is greater than other flower teeth, the clearance between two adjacent flower teeth on interior flower tooth structure 211 can't cup joint on location tooth 12, make only breach 212 position just can cooperate with location tooth 12, the inner wall joint with breach 212 between the both sides limit through location tooth 12 promptly, form the closed structure, the location cooperation of fixed position has been realized. Through this scheme, can realize spline housing 21 and spline rod 1 at the fixed cooperation mode of specific position, need not to increase the location axle sleeve.
