Axle core manufacturer: screw use


Axis core manufacturer: The important role of the screw is to convert rotary motion into linear motion or linear motion into rotary motion. The ball screw is composed of screw, nut and ball, which can convert rotary motion into linear motion. This is a further development of the ball screw. Because the friction resistance is very small, the ball screw is widely used in various precision instruments. Today, the editor introduces the types, uses and characteristics of the screw. So, let's take a look at the purpose of the screw!


Axle core manufacturer: 1. screw use:


In order to adapt to various uses, the screw provides many standardized products, which are now widely used in machine tools. Based on the technology accumulated over the years, starting with materials, heat treatment, manufacturing, inspection and other technologies, after strict quality inspection and management, the ball screw in the ball screw has a certain high reliability. Among them, the end cap type ball screw adopts precision machine tools, electronic machinery and high-speed machinery, and the high-speed ball screw adopts antenna drivers such as cosmic industry. Now the use of screws is more and more extensive.


Type of 2. screw:


Ball screw nuts are classified according to the steel ball circulation method, including end cover type, circulation type and elbow type.


Axis manufacturers: elbow generally use SBN, BNF, BNT, BNFN, BIF and other models, is a typical nut. The loop formulation is divided into five models: DK,DKN,DIK,JPF and DIR. These models are small nuts that can be circulated, change the direction of advancement of the steel ball, and return to the original position on the outer diameter of these threaded shafts. Finally, the end cover type, SBK, SDA, SBKH, WHF, BLK, WGF, BLW, WTF, CNF, BLR and other models are all nuts with good high-speed propulsion.



Shaft core manufacturer: The above is the use, type, use and other characteristics of the screw, but the surface thread of the screw has been specially treated, so it is necessary to take appropriate measures before surface treatment.


Shaft core manufacturer: shaft structure for easy disassembly and maintenance


Axle core manufacturer: The shaft is an assembly that can be seen everywhere in daily life. It plays the role of connecting the main parts of the product and bearing the bending moment and torque in the rotating work. As for the shaft structure applied to the baler, the existing baler is generally equipped with a shaft structure, which is generally integrated. Generally, there is a gear structure on the rotating shaft. The gear is connected to the chain through the gear, and the gear is connected to the motor. The motor drives the chain to rotate to make the gear rotate. The gear drives the rotating shaft to rotate, and the swing arm connected with the rotating shaft works to package the articles to be packaged. The shaft structure is a mechanical structure, which will cause the shaft to wear after working for a long time.



Shaft core manufacturer: However, it is not easy to detect the wear of the rotating shaft structure. It will only be noticed when the machine is at high temperature, large beating range, and abnormal noise. But when found, the shaft structure has been seriously worn, the packer has caused serious failure. Due to the heavy structure of the shaft or the compact structure of the packer, it is not convenient to disassemble and maintain the shaft.


Shaft core manufacturer: technical points: in view of the above problems existing in the prior art, the technical personnel proposed a shaft structure. The technical problem to be solved by the shaft structure is how to make the shaft structure easy to disassemble and repair.



Shaft core manufacturer: The shaft structure can be realized through the following technical solutions: a shaft structure, including a body, characterized in that the body includes a connecting shaft 1. a connecting shaft and a base, and one end of the connecting shaft is integrally formed with a flange The first, the two ends of the connecting shaft are integrally formed with gears, and the first flange abuts on the plate surface of the gear and is detachably connected; the second connecting shaft has a mounting hole through the end surfaces of the second connecting shaft.




Shaft core manufacturer: The connecting shaft is installed in the mounting hole, one end of the transmission shaft is detachably installed in the mounting hole of the second connecting shaft, and the other end extends in both directions of the flange. The structure of the rotating shaft is divided into three parts: the connecting shaft 1. the connecting shaft two and the base, the flange plate one at one end of the connecting shaft is detachably connected with the gear end face of the connecting shaft two, and one end face of the connecting shaft two is butted with one end face of the base; The second connecting shaft is provided with a mounting hole connected with the second mounting hole, and the first mounting hole is provided with a transmission shaft. One end of the transmission shaft is detachably connected to the inner wall of the mounting hole 1, and the other end passes through the mounting holes 1 and 2, so that the connecting shaft 2 and the base 3 are connected together, and the connecting shaft 1, the connecting shaft 2 and the base are realized. The detachable connection between the two is convenient for troubleshooting and maintenance of the connecting shaft structure.



Shaft core manufacturer: In the above-mentioned rotating shaft structure, the flange plate 1 has a plurality of fixing holes 1, the fixing hole 1 is circumferentially arranged along an edge of the flange plate, the gear has a plurality of fixing holes 2 at the corresponding position, and the connecting shaft 1 passes through The bolt 1 passing through the fixing hole 1 and the fixing hole 2 is fixed on the connecting shaft 2. The flange 1 is provided with a plurality of fixing holes 1, the fixing holes 1 are circumferentially arranged along an edge of the flange panel, and the gear is also provided with a plurality of fixing holes corresponding to positions, so that the connecting shaft 1 originally leaning on an end surface of the gear is fixed on the gear by bolts 1 passing through the fixing holes 1 and 2, and the connecting shaft 1 and the connecting shaft 2 are fixed and detachable.




Shaft core manufacturer: Compared with the prior art, the present invention has the following advantages: 1. The connecting shaft structure is divided into multiple sections, and the connecting shaft 1. connecting shaft 2 and the base are detachably connected, which is convenient for disassembly and maintenance;




Shaft core manufacturer: One end of the 2. transmission shaft is stuck in the mounting hole 1 on the connecting shaft 2, and the transmission shaft and the connecting shaft 2 are detachably connected by bolts 2 passing through the fixing holes 3 and 4 to realize the transmission shaft and The synchronous rotation of the connecting shaft 2; 3. Multiple bearings are installed in the base 3, the outer side wall of the bearing is close to the inner wall of the mounting hole 2, and the inner side wall is close to the transmission shaft, to prevent the drive shaft from touching the base and causing wear; 4. The base flange is accidentally injured and there are several fixing holes. Install the fastener to fix the base on the machine and prevent the base from rotating with the rotation of the connecting shaft.
