Description

Technical Field

[0001] This utility model belongs to the field of ball spline nut technology, and particularly relates to square flanged spline nuts. Background Technology

[0002] A ball spline nut is a high-precision, low-friction mechanical transmission component. It achieves rolling contact between the spline shaft and the nut through a built-in ball recirculation structure, thereby converting rotary motion into linear motion or simultaneously transmitting torque and axial motion. It combines the high-efficiency transmission characteristics of a ball screw with the guiding function of a spline connection, and is widely used in automated equipment, robots, CNC machine tools, and other fields requiring high precision, high rigidity, and low friction.

[0003] Traditional ball spline nuts require users to rigidly connect them to the equipment base or transmission components via an external fixing mechanism to secure them, resulting in high operating costs. Therefore, we propose a square flange spline nut. Utility Model Content

[0004] The purpose of this invention is to provide a square flanged key nut to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a square flanged key nut, comprising:

[0006] A splined shaft and a square flange, wherein the square flange is fixedly connected to the periphery of the splined shaft, and the top surface of the square flange has multiple mounting holes;

[0007] Multiple slots are provided at both ends of the spline shaft. Two plug blocks are inserted between the multiple slots. Two limiting plates are provided at the ends of the two plug blocks that are far apart from each other. Multiple insertion holes are provided on the two limiting plates. Multiple screws are provided in the multiple insertion holes. One end of each screw passes through the two plug blocks and extends into the spline shaft.

[0008] Based on the above structure, the splined shaft, square flange, and mounting holes ensure that the user can fix the splined shaft to the equipment base or transmission components through multiple mounting holes and the square flange. The slots and inserts ensure that the inserts can be inserted between two slots. The limit plates, sockets, and screws ensure that the user can insert multiple screws into multiple sockets respectively. The two inserts and two limit plates can be fixed to both ends of the splined shaft with two screws respectively. The circulation grooves and balls ensure that multiple balls can roll in two circulation grooves respectively.

[0009] Furthermore, the above technical solution also includes:

[0010] Two circulation grooves are formed between the two inserts and the spline shaft, and multiple balls are respectively arranged in the two circulation grooves.

[0011] In this technical solution, multiple balls are ensured to reduce the coefficient of friction between the spline shaft and the equipment base or transmission components, thereby significantly reducing energy consumption.

[0012] In the above technical solution, furthermore, the plurality of balls are movably connected to two circulation grooves respectively.

[0013] In this technical solution, it is ensured that multiple balls can roll in two separate circulation grooves.

[0014] In the above technical solution, furthermore, the plurality of screws are threadedly connected to the two insert blocks respectively.

[0015] In this technical solution, it is ensured that when the user rotates multiple screws, the screws can be acted upon by the threads of the two inserts respectively, and enter the two inserts respectively.

[0016] In the above technical solution, furthermore, multiple screws are threadedly connected to the spline shaft.

[0017] In this technical solution, it is ensured that when the user rotates multiple screws, the multiple screws can be acted upon by the spline shaft thread and enter the spline shaft.

[0018] Furthermore, in the above technical solution, the splined shaft and the square flange are integrally formed.

[0019] In this technical solution, it is ensured that there is no assembly gap between the spline shaft and the square flange, so that the stress transmission can be continuous, thereby increasing the bending stiffness by 30% to 50%.

[0020] In the above technical solution, the socket and screw are further connected and mated.

[0021] In this technical solution, it is ensured that the screw can be properly inserted into the socket.

[0022] The beneficial effects of this utility model are:

[0023] This square flange spline nut, with its designed spline shaft, square flange, and mounting holes, allows users to secure the spline shaft to the equipment base or transmission components via multiple mounting holes and the square flange. The slots and inserts ensure that the inserts can be inserted between two slots. The limiting plates, sockets, and screws allow users to insert multiple screws into multiple sockets, and the two inserts and two limiting plates can be secured to both ends of the spline shaft with two screws respectively. The circulating grooves and balls allow multiple balls to roll within two circulating grooves. This design solves the problem of high operating costs associated with traditional ball spline nuts, which required external fixing mechanisms for rigid connection to the equipment base or transmission components.

[0036] A splined shaft 1 and a square flange 2 are fixedly connected to the periphery of the splined shaft 1. The top surface of the square flange 2 has multiple mounting holes 3.

[0037] Multiple slots 4 are respectively opened at both ends of the spline shaft 1. Two plug blocks 5 are inserted between the multiple slots 4. Two limiting plates 6 are respectively provided at the ends of the two plug blocks 5 that are far apart from each other. Multiple insertion holes 7 are respectively opened on the two limiting plates 6. Multiple screws 8 are respectively provided in the multiple insertion holes 7, and one end of the multiple screws 8 passes through the two plug blocks 5 and extends into the spline shaft 1.

[0038] Example 2:

[0040] Two circulation grooves 9 are formed between two insert blocks 5 and spline shaft 1, and multiple balls 10 are respectively arranged in the two circulation grooves 9.

[0041] When the spline shaft 1 moves, the balls 10 roll in the circulation groove 9, which transforms sliding friction into rolling friction, significantly reducing frictional resistance and ensuring that multiple balls 10 can reduce the coefficient of friction between the spline shaft 1 and the equipment base or transmission components, thus significantly reducing energy consumption.

[0042] Example 3:

[0043] This embodiment provides a square flanged key nut, which, in addition to the technical solutions of the above embodiments, also has the following technical features: multiple balls 10 are movably connected to two circulation grooves 9 respectively.

[0044] This ensures that multiple balls 10 can roll in two circulation grooves 9 respectively.

[0045] Example 4:

[0046] This embodiment provides a square flanged key nut, which, in addition to the technical solution of the above embodiment, also has the following technical features: multiple screws 8 are threadedly connected to two insert blocks 5 respectively.

[0047] Specifically, it is ensured that when the user rotates multiple screws 8, the multiple screws 8 can be respectively subjected to the action of the threads of the two inserts 5 and enter the two inserts 5 respectively.

[0048] Example 5:

[0049] This embodiment provides a square flanged spline nut, which, in addition to the technical solutions of the above embodiments, also has the following technical features: multiple screws 8 are threadedly connected to the spline shaft 1.

[0050] Specifically, it is ensured that when the user rotates multiple screws 8, the multiple screws 8 can be acted upon by the thread of the spline shaft 1 and enter the spline shaft 1.

[0056] This ensures that screw 8 can be properly inserted into socket 7.

[0057] In use, the user places multiple ball bearings 10 into two circulation grooves 9, then inserts two insert blocks 5 into multiple slots 4. The user then manually places two limiting plates 6 on opposite sides of the insert blocks 5. Next, the user inserts multiple screws 8 into multiple sockets 7 and rotates them using a tool. This causes the screws 8 to move towards the spline shaft 1 under the action of the threads of the insert blocks 5.
