Abstract
Description
Technical Field
[0001] This utility model relates to an internal and external spline mechanism, and more particularly to a floating internal and external spline mechanism that can be quickly and accurately connected. Background Technology
[0002] Currently, in some fields where internal and external spline mating mechanisms are used, manual mating is sometimes used, which is slow and inefficient; while automatic mating is sometimes used, but the probability of misalignment and tooth tip collision between the internal and external splines is high, resulting in a low mating success rate and affecting production progress. Utility Model Content
[0003] The purpose of this invention is to provide a floating internal and external spline mechanism that can be quickly and accurately connected, thereby solving the problems mentioned above.
[0004] To achieve the above-mentioned objectives, this utility model adopts the following technical solution:
[0005] A floating internal and external spline mechanism that can be quickly and accurately connected includes a fixed base, on which a floating base is fixedly connected. The floating base has an annular structure. A plurality of spring plungers are evenly arranged around the outer ring of the floating base. A shaft limiting structure is provided in the inner ring of the floating base. The spring plungers press against the outer wall of the shaft limiting structure to clamp and adjust the position of the shaft limiting structure. The shaft limiting structure has a bearing inside which an internal spline shaft is connected. One end of the internal spline shaft has an internal spline that mates with an external spline.
[0006] A further feature of this invention is that the insert teeth of the internal and external splines are provided with guide surfaces.
[0007] Further technical features of this utility model: The shaft limiting structure includes a round nut embedded in the inner ring of the floating seat, and an inner spline sleeve disposed within the round nut. A spring plunger abuts against the outer wall of the round nut, and a bearing is disposed inside the inner spline sleeve.
[0008] The beneficial effects of this utility model are:
[0009] This invention employs a floating structure, which allows the internal spline to have a certain radial floating amount, accommodating coaxiality deviations between the internal and external splines during insertion and improving the insertion success rate. Furthermore, the insertion teeth of the internal and external splines are machined with guide surfaces at a certain angle, reducing the probability of collision between the internal and external spline teeth and enabling the internal and external splines to be quickly and smoothly inserted during insertion. Attached Figure Description
[0010] To more clearly illustrate the technical solutions in the embodiments of this utility model, the drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0013] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0014] like Figure 1 This embodiment provides a floating internal and external spline mechanism that can be quickly and accurately connected, including a fixed base 10, on which a floating base 11 is fixedly connected. The floating base 11 has an annular structure. A plurality of spring plungers 12 are evenly arranged around the outer ring of the floating base 11. A shaft limiting structure is provided in the inner ring of the floating base 11. The spring plungers 12 press against the outer wall of the shaft limiting structure to clamp and adjust the position of the shaft limiting structure. The shaft limiting structure is provided with a bearing inside which an internal spline shaft 13 is connected. One end of the internal spline shaft 13 is provided with an internal spline 17 that mates with an external spline 18.
[0015] The spring plunger 12 has a radial float of 3mm. By clamping the outer wall of the shaft limiting structure with the spring plunger 12, the shaft limiting structure also has a float of 3mm, thereby allowing the inner and outer splines 18 to have coaxiality deviation during insertion and improving the insertion success rate.
[0016] The inner spline 17 and outer spline 18 are provided with guide surfaces 14 at their insertion ends. This reduces the probability of collision between the inner and outer spline 18 teeth, allowing the inner and outer splines 18 to be inserted quickly and smoothly during insertion.
[0017] In the above structure, the shaft limiting structure includes a round nut 15 embedded in the inner ring of the floating seat 11, and an inner spline sleeve 16 disposed in the round nut 15. The spring plunger 12 abuts against the outer wall of the round nut 15, and the bearing is disposed inside the inner spline sleeve 16.
[0018] By adding a round nut 15, the spring plunger 12 is prevented from directly pressing against the outer wall of the inner spline sleeve 16, thus avoiding deformation of the outer wall of the inner spline sleeve 16 and ensuring the safety of the inner spline shaft 13.
[0019] In this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
[0020] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0021] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
