Description

Technical Field

[0001] The utility model relates to the technical field of mechanical parts, and more specifically, to a spline connecting sleeve. Background Art

[0002] The spline connection consists of internal splines and external splines. Both internal and external splines are multi-tooth parts. The splines on the inner cylindrical surface are internal splines, and the splines on the outer cylindrical surface are external splines. In the existing mechanical field, a spline connecting sleeve is usually used, that is, a combination of a spline shaft and a spline sleeve. The spline end of the spline shaft is inserted into the spline hole of the spline sleeve and meshes with each other.

[0003] Since the connection between the external spline and the internal spline is mostly a fixed connection, after long-term use, the connection between the external spline and the internal spline will loosen and wear, and it needs to be replaced. At the same time, the cost of replacing the internal and external splines is high. Therefore, in order to solve the above problem, a spline connecting sleeve is specially proposed.

[0006] (2) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides a spline connecting sleeve, including an inner spline, an outer spline and a fixed ring, the outer spline is sleeved on the surface of the inner spline, there are two fixed rings, the fixed ring is sleeved on the surface of the inner spline and is located on both sides of the outer spline, the inner spline surface is provided with a plurality of mounting holes, an L-shaped annular groove is provided inside the fixed ring, an annular rotating block is slidably connected inside the L-shaped annular groove, a plurality of movable grooves are provided inside the L-shaped annular groove, a mounting block is slidably connected inside the movable groove, an annular threaded plate is fixedly connected to the side of the annular rotating block, a strip threaded plate is fixedly connected to the side of the mounting block, the annular threaded plate and the strip threaded plate are meshed with each other, and the bottom end of the mounting block is clamped in the fixing hole.

[0008] When using a spline connecting sleeve of the present technical solution, an annular rotating block is set. When the equipment needs to be replaced, people rotate the annular rotating block, and drive the mounting block to slide in the movable groove through the annular threaded plate and the strip threaded plate, so that the bottom end of the mounting block is disengaged from the mounting hole, and then pull the fixing ring to remove the two fixing rings, and the internal spline and the external spline can be disassembled, thereby achieving the effect of facilitating the disassembly of the internal spline and the external spline, which is beneficial for the staff to maintain the equipment at a later time.

[0009] Furthermore, a plurality of fixing holes are provided inside the fixing ring, a plurality of shrinking holes are provided inside the annular rotating block, and a compression spring is fixedly connected to the inner side surface of the shrinking hole.

[0017] 2. The spline connection sleeve is provided with an extrusion spring, a fixing hole and a fixing block. Under the action of the extrusion spring, the fixing hole and the fixing block, after the fixing ring is installed, the position of the annular rotating block can be limited, thereby preventing the annular rotating block from loosening and making the use more convenient.

[0018] 3. This spline connecting sleeve increases the connection area between the fixing ring and the inner spline and the outer spline by setting the first positioning hole, the second positioning hole and the positioning rod and utilizing the mutual cooperation between the first positioning hole, the second positioning hole and the positioning rod, thereby enhancing the stability of the equipment connection.
