Description

Technical Field

[0001] This utility model relates to the field of spline shaft technology, specifically to an anti-slip toothed spline shaft. Background Technology

[0002] Splined shafts are a type of mechanical transmission device, functioning similarly to parallel keys, semi-circular keys, and wedge keys—transmitting mechanical torque. They have longitudinal keyways on their outer surface, and rotating components fitted onto the shaft also have corresponding keyways to maintain synchronous rotation with the shaft. While rotating, some can also slide longitudinally on the shaft, such as gearbox shift gears. Splined shafts are broadly classified into rectangular splined shafts and involute splined shafts. Rectangular splined shafts are widely used, while involute splined shafts are used for connections with high loads, high centering accuracy requirements, and large dimensions. Rectangular splined shafts are commonly used in aircraft, automobiles, tractors, machine tool manufacturing, agricultural machinery, and general mechanical transmission devices. Due to their multi-tooth operation, rectangular splined shafts have high load-bearing capacity, good centering and guiding properties, and their shallow tooth roots minimize stress concentration. Furthermore, splined shafts exhibit minimal weakening of the shaft and hub strength, are relatively easy to machine, and high precision can be achieved through grinding.

[0003] This application improves upon the existing technology. In the existing technology, the outer wall of the spline shaft is too smooth, which makes it inconvenient for users to use and reduces the user experience.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

Detailed Implementation

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0024] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0025] It should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0026] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0027] 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 based on the specific circumstances.

[0028] Please see Figure 1-7 An embodiment of this utility model provides: an anti-slip toothed spline shaft, including a shaft body 7, a connecting rod 8 fixedly connected to the right side of the shaft body 7, an external spline 9 fixedly sleeved on the outer wall of the connecting rod 8, a plurality of anti-slip slider bodies 14 fixedly arranged on the outer wall of the external spline 9, an anti-slip slider angle 15 is provided between two adjacent anti-slip slider bodies 14, a fourth angle 13 is provided on the right side of the connecting rod 8, the angle of the fourth angle 13 is the third angle 12, the number of anti-slip slider bodies 14 is ten, the angle of the anti-slip slider angle 15 is 79.2°, and an installation rod 6 is fixedly connected to the left side of the shaft body 7;

[0029] Specifically, such as Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, when using this splined shaft, the anti-slip body 14 can increase the friction between the splined shaft and the user's hand, making it easier for the user to use and thus improving the user experience. This solves the problem that existing splined shafts are not easy to use and reduce the user experience because the outer wall of the splined shaft is too smooth.

[0030] The first shaft seat 1 is fixedly connected to the left side of the mounting rod 6. The fifth shaft seat 5 is fixedly connected to the left side of the first shaft seat 1. The fourth shaft seat 4 is fixedly connected to the left side of the fifth shaft seat 5. The third shaft seat 3 is fixedly connected to the left side of the fourth shaft seat 4. The second shaft seat 2 is fixedly connected to the left side of the third shaft seat 3. A third included angle 12 is provided between the first shaft seat 1 and the mounting rod 6. The angle of the third included angle 12 is 135°. A second included angle 11 is provided between the fourth shaft seat 4 and the fifth shaft seat 5. The angle of the second included angle 11 is 135°. A first included angle 10 is provided between the second shaft seat 2 and the third shaft seat 3. The angle of the first included angle 10 is 90°.

[0031] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, in use, the splined shaft can be improved not only by the cooperation of the first shaft seat 1, the second shaft seat 2, the third shaft seat 3, the fourth shaft seat 4, the fifth shaft seat 5, the mounting rod 6, the shaft body 7, the first included angle 10, the second included angle 11 and the third included angle 12, but also by the static torsional strength of the splined shaft, resulting in good performance.

[0032] Working principle: In this application, when the spline shaft is used, the friction between the anti-slip block body 14 and the user's hand can be increased, thereby facilitating the user's use and improving the user experience. Secondly, through the coordinated use of the first shaft seat 1, the second shaft seat 2, the third shaft seat 3, the fourth shaft seat 4, the fifth shaft seat 5, the mounting rod 6, the shaft body 7, the first included angle 10, the second included angle 11 and the third included angle 12, not only can the static torsional strength of the spline shaft be improved, but also the tensile strength of the spline shaft can be improved, resulting in good performance.

[0033] All standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. At the same time, the electrical components mentioned in this application are all connected to an external power supply and control switch when in use. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. Therefore, this utility model will not explain the control method and circuit connection in detail. Moreover, the external controller mentioned in the specification can play a control role for the electrical components mentioned in this article, and the external controller is a conventional known device.
