Description

Technical Field

[0001] The utility model belongs to the technical field of spline shafts, and in particular relates to a spline shaft anti-dropping structure. Background Art

[0002] The spline shaft is a type of mechanical transmission used to transmit mechanical torque. It is provided with a keyway, and the rotating part connected to it also has a corresponding keyway, which can keep it rotating synchronously with the shaft. The motor spline shaft connected to the gearbox can slide longitudinally on the shaft to achieve the gear shifting requirements of the gearbox.

[0003] The problem with the prior art is that the traditional way of connecting two spline shafts is to insert the spline of one shaft into the spline hole of the other shaft to achieve the connection, but this connection method is not strong. When the spline shafts rotate at high speed, it is easy for the two sets of spline shafts connected to each other to be thrown off. Therefore, we propose a spline shaft anti-dropping structure.

[0006] As a preferred embodiment of the utility model, the anti-falling assembly includes a screw rod, the screw rod is threadedly connected to the inside of two groups of threaded holes, and two groups of fixing blocks are detachably connected to the surface of the screw rod.

[0010] As a preferred embodiment of the utility model, two groups of reinforcement plates are detachably connected to the surfaces of the four groups of mounting rods, and hinges are commonly provided between one side of the two groups of reinforcement plates.

[0011] As a preferred embodiment of the present invention, the other sides of the surfaces of the two groups of reinforcement plates are fixedly connected with mounting plates, and the corresponding two groups of mounting plates are commonly threadedly connected with second screws.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The utility model adopts the design of the first spline shaft, the second spline shaft, the anti-dropping component and the threaded hole. When in use, the first spline shaft and the second spline shaft can be connected by using the anti-dropping component and the threaded hole. The anti-dropping component can prevent the first spline shaft and the second spline shaft from separating during high-speed rotation, thereby achieving the effect of ensuring the stability of the connection between the first spline shaft and the second spline shaft.

[0014] 2. The utility model is designed with a screw rod, a threaded hole, a fixing block, a connecting plate and a first screw. When in use, the screw rod is used to connect the screw rod to the inside of two groups of threaded holes, thereby connecting the first spline shaft and the second spline shaft. Subsequently, the fixing block and the connecting plate are sleeved on the surface of the screw rod and fit each other. Next, the connecting block is used to fix the two groups of fixing blocks, thereby achieving the effect of facilitating the installation of the anti-fall-off component.

[0015] 3. The utility model adopts the design of the fixing block, the spring pull rod, the connecting block, the fixing rod, the mounting rod and the bonding plate. When in use, the spring pull rod will pull the connecting block to move. During the movement, the mounting rods and the bonding plate on both sides of the fixing rod will be pulled to fit the surfaces of the first spline shaft and the second spline shaft, thereby achieving the effect of facilitating the reinforcement plate to reinforce the anti-falling component and the first spline shaft and the second spline shaft.

[0016] 4. The utility model adopts the design of the mounting rod, the reinforcing plate, the hinge, the mounting plate and the second screw. When the bonding plate is in close contact with the surface of the first spline shaft and the second spline shaft, the reinforcing plate is rotated by using the hinge to make the two groups of reinforcing plates tightly fix the mounting rods on the surface of the four bonding plates.

The surface of the screw 301 is detachably connected with two groups of fixing blocks 302; both sides of the surface of the two groups of fixing blocks 302 are fixedly connected with connecting plates 304, and two groups of first screws 303 are threadedly connected between the two corresponding groups of connecting plates 304.

[0026] The above scheme is adopted: through the design of the screw 301, the threaded hole 4, the fixing block 302, the connecting plate 304 and the first screw 303, when in use, the screw 301 is used to connect the screw 301 to the inside of the two groups of threaded holes 4, thereby connecting the first spline shaft 1 and the second spline shaft 2, and then the fixing block 302 and the connecting plate 304 are put on the surface of the screw 301 and fit each other, and then the two groups of fixing blocks 302 are fixed by the connecting block 305, thereby achieving the effect of facilitating the installation of the anti-fall-off component 3.

[0027] refer to Figure 3 One side of the surface of the two groups of fixed blocks 302 is fixedly connected with a spring pull rod 306, the piston ends of the two groups of spring pull rods 306 are fixedly connected with the connecting blocks 305, and the two sides of the surfaces of the two groups of connecting blocks 305 are fixedly connected with fixing rods 307; both sides of the two groups of fixing rods 307 are fixedly connected with mounting rods 308, and one side of the surface of the two groups of mounting rods 308 is fixedly connected with a bonding plate 309, and the two groups of bonding plates 309 are respectively bonded with the surfaces of the first spline shaft 1 and the second spline shaft 2.

[0028] The above scheme is adopted: through the design of the fixing block 302, the spring pull rod 306, the connecting block 305, the fixing rod 307, the mounting rod 308 and the bonding plate 309, when in use, the spring pull rod 306 will pull the connecting block 305 to move, and during the movement, the mounting rod 308 and the bonding plate 309 on both sides of the fixing rod 307 will be pulled to fit the surfaces of the first spline shaft 1 and the second spline shaft 2, thereby achieving the effect of facilitating the reinforcement plate 311 to reinforce the anti-falling component 3 and the first spline shaft 1 and the second spline shaft 2.

[0029] refer to Figure 3 The surfaces of the corresponding four groups of mounting rods 308 are commonly detachably connected with two groups of reinforcement plates 311, and a hinge 310 is commonly set between one side of the corresponding two groups of reinforcement plates 311; the other side of the surface of the two groups of reinforcement plates 311 is fixedly connected with a mounting plate 312, and the corresponding two groups of mounting plates 312 are commonly threadedly connected with a second screw 313.

[0030] The above scheme is adopted: through the design of the mounting rod 308, the reinforcing plate 311, the hinge 310, the mounting plate 312 and the second screw 313, when the bonding plate 309 is close to the surface of the first spline shaft 1 and the second spline shaft 2, the hinge 310 is used to rotate the reinforcing plate 311, so that the two groups of reinforcing plates 311 are tightly fixed to the mounting rods 308 on the surface of the four groups of bonding plates 309, and then the second screw 313 is used to connect between the mounting plates 312 on the surface of the two groups of reinforcing plates 311 to fix the reinforcing plates 311, thereby achieving the effect of reinforcing the connection between the first spline shaft 1 and the second spline shaft 2 to prevent separation.

[0031] The working principle of this utility model:

[0032] When in use, the screw rod 301 is used to connect the screw rod 301 inside the two groups of threaded holes 4, thereby connecting the first spline shaft 1 and the second spline shaft 2, and then the fixing block 302 and the connecting plate 304 are sleeved on the surface of the screw rod 301 and fit each other, and then the two groups of fixing blocks 302 are fixed by the connecting block 305 to facilitate the installation of the anti-falling component 3, and the spring pull rod 306 will pull the connecting block 305 to move, and during the activity, the installation rods 308 and the fitting plates 309 on both sides of the fixing rod 307 will be pulled to fit the first spline shaft 1 and the second spline shaft 2. The surface is convenient for the reinforcement plate 311 to reinforce the anti-falling component 3 and the first spline shaft 1 and the second spline shaft 2. When the bonding plate 309 is close to the surface of the first spline shaft 1 and the second spline shaft 2, the hinge 310 is used to rotate the reinforcement plate 311, so that the two groups of reinforcement plates 311 are tightly fixed to the mounting rods 308 on the surface of the four groups of bonding plates 309, and then the second screw 313 is used to connect between the mounting plates 312 on the surfaces of the two groups of reinforcement plates 311 to fix the reinforcement plate 311, so as to reinforce the connection between the first spline shaft 1 and the second spline shaft 2 to prevent separation.

[0033] To sum up: this kind of spline shaft anti-dropping structure, through the structure of anti-dropping component 3, screw 301, fixed block 302, first screw 303, connecting plate 304, connecting block 305, spring pull rod 306, fixed rod 307, mounting rod 308, bonding plate 309, hinge 310, reinforcement plate 311, mounting plate 312 and second screw 313, solves the problem that the traditional way of connecting two spline shafts is to insert the spline of one shaft into the spline hole of another shaft to achieve connection, but this connection method is not firm. When the spline shaft rotates at high speed, it is easy to throw off the two sets of spline shafts connected to each other.
