Description

Technical Field

[0001] This utility model relates to the field of spindle technology, and in particular to a spindle component with quick-release function. Background Technology

[0002] In practical applications of spindles, flanges are a common and important connecting component, typically used to achieve reliable connection and power transmission between shafts or between shafts and rotating parts (such as gears, pulleys, impellers, etc.).

[0003] Some flanges are installed using a plug-in fit, and are installed by mating with holes on the shaft. With the help of a certain fit clearance, the operator can relatively easily put the flange into the predetermined position on the shaft. Then, torque is usually transmitted through keys and pins, and the final fixation is completed by axial fastening methods such as shaft shoulder positioning, lock nuts or retaining rings.

[0004] However, in practical applications, this type of spindle and flange assembly method results in a tighter fit between the shaft and flange during long-term operation due to factors such as micro-deformation and thermal effects generated when the shaft and flange holes transmit torque and bear alternating loads. This makes it difficult to pull out during disassembly, leading to disassembly difficulties. Therefore, a solution is urgently needed. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a spindle component with quick-release function.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A spindle component with quick-release function includes a spindle body. Multiple fastening blocks are distributed circumferentially on the outer wall of one end of the spindle body through a mounting groove. A through hole is opened in the middle of the fastening block and a pair of uprights are inserted through it. A ball bearing is movably installed on the upper wall of the upright, and the upper wall of the ball bearing protrudes slightly from the outer wall of the spindle body. The shaft is rotatably mounted with a flat threaded disc, the threaded surface of which is screwed to the bottom wall of the fastening block, and one end of the flat threaded disc is connected to the adjusting screw.

[0007] In addition, a preferred structure is that the outer wall of the shaft is provided with multiple mounting grooves at equal intervals along the circumference, and fastening blocks are fitted in the mounting grooves to limit the movement of the fastening blocks within the mounting grooves.

[0008] Furthermore, in a preferred configuration, a pair of uprights are mounted on the bottom wall of the mounting groove, with the uprights passing through the fastening block and the top of the uprights extending out of the outer wall of the fastening block.

[0009] In addition, a preferred structure is that the top of the upright has a spherical groove, and partially exposed ball bearings are constrained and installed in the groove.

[0010] Furthermore, a preferred structure is that, in its natural state, the upper surface of the fastening block is lower than the outer wall of the shaft body, exhibiting a sunken structure.

[0011] In addition, a preferred structure is that a flange joint is inserted into one side of the shaft, and the flange joint is fastened to the flange plate provided in the middle of the shaft by fasteners.

[0012] The beneficial effects of this utility model are as follows: In this invention, the rotating adjusting screw drives the planar threaded disc to rotate, thereby causing multiple fastening blocks on the shaft to simultaneously disengage from the flange joint, greatly reducing frictional interference during disassembly. At the same time, the balls are simultaneously exposed and come into contact with the inner wall of the flange joint. Through rolling friction, the smoothness and efficiency of the disassembly operation are significantly improved, ultimately achieving a reliable quick disassembly function.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-5 A spindle component with quick-release function includes a spindle body 1. Multiple fastening blocks 3 are distributed circumferentially on the outer wall of one end of the spindle body 1 through the mounting groove 7. A through hole is opened in the middle of the fastening block 3 and a pair of uprights 6 are inserted through it. A ball bearing 61 is movably installed on the upper wall of the uprights 6. The upper wall of the ball bearing 61 protrudes slightly from the outer wall of the spindle body 1. A flat threaded disc 41 is rotatably mounted on the shaft 1. The threaded surface of the flat threaded disc 41 is screwed to the bottom wall of the fastening block 3. One end of the flat threaded disc 41 is connected to the adjusting screw 4. The adjusting screw 4 is rotatably mounted in the middle of one end of the shaft 1.

[0017] Multiple mounting slots 7 are equidistantly provided on the outer wall of the shaft 1 along the circumference. Fastening blocks 3 are fitted in the mounting slots 7 to limit their movement. The fastening blocks 3 can achieve vertical displacement within the mounting slots 7. A pair of uprights 6 are installed on the bottom wall of the mounting slots 7. The uprights 6 pass through the fastening blocks 3 and the top of the uprights protrudes from the outer wall of the fastening blocks 3.

[0018] A flange connector 5 is inserted into one side of the shaft body 1, and the flange connector 5 is fastened to the flange 2 set in the middle of the shaft body 1 by fasteners.

[0019] The top of the upright 6 is provided with a spherical groove, and a partially exposed ball bearing 61 is constrained and installed in the groove.

[0020] In its natural state, the top surface of the fastening block 3 is lower than the outer wall of the shaft 1, forming a sunken structure, thereby preventing the flange joint 5 from contacting the surface of the fastening block 3 and forming frictional interference during installation.

[0021] In this embodiment, when disassembling the flange joint 5, the adjusting screw 4 is loosened to drive the flat threaded disc 41 to rotate. The rotation of the flat threaded disc 41 drives the multiple fastening blocks 3 connected to it to move through the threads, so that the fastening blocks 3 descend in the mounting groove 7 and separate from the inner wall of the flange joint 5. At this time, the fasteners used to connect the flange 2 and the flange joint 5 are removed, and the flange joint 5 is pulled outward to complete the disassembly.

[0022] During this process, after the fastening block 3 moves down, the ball 61 at the top of the upright 6 is exposed and comes into contact with the inner wall of the flange joint 5. As multiple fastening blocks 3 descend at the same time, their contact area with the flange joint 5 is significantly reduced, thereby greatly reducing the frictional resistance during disassembly. At the same time, with the help of the rolling contact characteristics of the ball 61, the sliding friction is further converted into rolling friction, making the flange joint pull-out operation more effortless and smooth, effectively improving disassembly efficiency and convenience.

[0023] During actual installation, there is a preset radial interference between the flange joint 5 and the ball 61. The interference fit causes the ball 61 to bear radial load and produce a small amount of elastic deformation. This deformation is within the design allowable range and will not affect the normal rotation function of the ball.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
