Description

Technical Field

[0001] This utility model relates to the technical field of transmission connection devices between motors and gearboxes of large equipment, specifically a disassembled coupling. Background Technology

[0002] In existing large-scale equipment (including mining equipment), the output force of the motor is generally transmitted using pin couplings. Traditional pin couplings consist of two parts, essentially a pair. Due to the limited space between the gearbox and the motor, replacement requires the entire motor to be removed first. Because the ends of the motor shaft and drive shaft are interference-fitted, the coupling cannot be pulled out directly; it usually requires heating to remove it. Installation also requires heat fitting, followed by adjustment of the coaxiality of the motor drive shaft (the pair of couplings), making the entire process very cumbersome and time-consuming.

[0003] Furthermore, traditional couplings frequently fail due to prolonged wear. Replacement of worn polyester gaskets between the two couplings, or worn splines on the drive shaft, all require disassembling the coupling, a cumbersome process. Due to the limited space between gearboxes, replacement often necessitates removing the entire motor before pulling out the coupling. Installation is also extremely difficult, requiring adjustment of the coaxiality of the two couplings after each motor disassembly and reassembly, wasting time and effort and impacting production. Utility Model Content

[0004] The purpose of this invention is to provide a disassembled coupling to solve the problems mentioned in the background art, such as the time-consuming and laborious process of replacing the polyester gaskets between the two half couplings, and the wear of the coupling and spline.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a disassembled coupling, comprising a first half-coupling and a second half-coupling with identical structures; the first half-coupling includes a first half-coupling flange in a semi-circular shape and a first half-coupling locking ring coaxial with it, and a plurality of first flange holes are evenly arranged on the same circumference of the first half-coupling; the first half-coupling locking ring has a plurality of first through holes perpendicular to the plane of its shaft center evenly arranged near its two sides; the second half-coupling includes a second half-coupling flange in a semi-circular shape and a second half-coupling locking ring coaxial with it, and a plurality of second flange holes are evenly arranged on the same circumference of the second half-coupling, and a plurality of second through holes perpendicular to the plane of its shaft center are evenly arranged near its two sides.

[0006] Preferably, the flange of the first half-coupling is fixedly connected to the locking ring of the first half-coupling and the two have the same inner diameter.

[0007] Preferably, the second half-coupling locking ring and the second half-coupling flange are fixedly connected and have the same inner diameter.

[0008] Preferably, the first half-coupling flange and the second half-coupling flange form a complete coupling flange, and the first flange hole and the second flange hole are located on the same circumference.

[0009] Preferably, the first half-coupling locking ring and the second half-coupling locking ring form a complete cylindrical coupling locking ring, with the corresponding first through hole and second through hole coaxially arranged and connected as a whole by bolts.

[0010] Preferably, the two complete coupling flanges are connected as one unit by bolts passing through the first through hole and the second through hole.

[0011] Preferably, a keyway is provided on the motor spindle or the transmission shaft of the gearbox, and a protruding key that matches the keyway is provided on the inner wall of the locking ring of the first half coupling or the locking ring of the second half coupling.

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

[0013] 1. The disassembled coupling provided by this utility model allows for easy replacement of the coupling by simply unscrewing the fastening screws without removing any parts, thus achieving the effect of convenient replacement, saving time and effort.

[0014] 2. The disassembled coupling provided by this utility model can completely realize the disassembly and installation of the coupling and the interference clearance fit between the coupling and the shaft by only a few screws (disassembly and installation). There is no need to adjust the coaxiality of the two couplings (because the reference point of the motor and the gearbox remains unchanged). Since it is locked by screws, there will be no gap between the coupling and the spline shaft, thus no wear will occur, reducing damage to the spline shaft and the coupling.

[0015] 3. The disassembly coupling provided by this utility model can save 80% of the time when replacing and installing the polyester gasket on the damaged coupling pin. The replacement of a traditional coupling requires about 3 people and 8 hours, while the new coupling can be completed by only 1 person in 1 hour.

[0016] 4. The disassembled coupling provided by this utility model is used for connecting the main motor and coupling of large vertical lathes, drilling machines and mining equipment, as well as for connecting small servo motors and lead screws, and has broad application prospects.

Detailed Implementation

[0023] To enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings and specific embodiments.

[0024] Please refer to Figure 1-5 , Figure 1 This is the front view of the present utility model; Figure 2 for Figure 1 Sectional view of AA; Figure 3 for Figure 1 Sectional view of BB; Figure 4 for Figure 1 Top view; Figure 5 This is a schematic diagram of the actual assembly and use of the coupling.

[0025] This utility model provides a disassembled coupling, including a first half coupling 1 and a second half coupling 2. The first half coupling 1 and the second half coupling 2 can be combined into a complete coupling. The coordinated use of the two complete couplings can complete the transmission connection between the motor and the gearbox of large equipment.

[0026] The first half-coupling 1 includes a semi-circular first half-coupling flange 11, and a plurality of first flange holes 12 are evenly arranged on the same circumference of the first half-coupling 11; a semi-circular first half-coupling locking ring 13 is provided on one side of the first half-coupling flange 11, the first half-coupling locking ring 13 and the first half-coupling flange 11 are coaxially arranged and have the same inner diameter; a plurality of first through holes 14 perpendicular to the plane where the axis is located are evenly arranged near the two sides of the first half-coupling locking ring 13.

[0027] The structure of the second half-coupling 2 is the same as that of the first half-coupling 1, including a semi-circular second half-coupling flange 21, and a plurality of second flange holes 22 are evenly arranged on the same circumference of the second half-coupling 21; a semi-circular second half-coupling locking ring 23 is provided on one side of the second half-coupling flange 21, the second half-coupling locking ring 23 and the second half-coupling flange 21 are coaxially arranged and have the same inner diameter; a plurality of second through holes 24 perpendicular to the plane where its axis is located are evenly arranged near the two sides of the second half-coupling locking ring 23.

[0028] The first half-coupling flange 11 and the second half-coupling flange 21 form a complete coupling flange. The first flange hole 12 and the second flange hole 22 are located on the same circumference. The first half-coupling locking ring 13 and the second half-coupling locking ring 23 form a complete cylindrical coupling locking ring. At the same time, the corresponding first through hole 14 and the second through hole 24 are coaxially arranged and can be bolted together.

[0029] In use, the first half-coupling 1 and the second half-coupling 2 are aligned to form a complete coupling, and bolts are used to connect them together through the first through hole 14 and the second through hole 24. Then, the complete coupling is fitted onto the shaft of the large equipment motor or gearbox, and the bolts passing through the first through hole 14 and the second through hole 24 are tightened. As the bolts are tightened, the complete coupling is connected to the shaft of the large equipment motor or gearbox by interference fit. Finally, bolts are used to connect the two complete couplings together through the first flange hole 12 and the second flange hole 22, thereby completing the transmission connection between the large equipment motor and the gearbox.

[0030] Furthermore, since the traditional connection between the coupling and the motor spindle or gearbox drive shaft is a keyway connection, a protruding key that matches the keyway is provided on the inner wall of the first half-coupling locking ring 13 or the second half-coupling locking ring 23. This can further strengthen the connection between the complete couplings and avoid the possibility of slippage during transmission.

[0031] The disassembled coupling provided by this utility model allows for easy replacement of the polyester gasket on the pin between the two half couplings without removing any parts. Only the fastening screws need to be unscrewed, achieving convenient replacement and saving time and effort. Disassembly and installation are accomplished entirely with a few screws, ensuring the coupling and shaft achieve an interference fit without adjusting the coaxiality of the two couplings. No clearance is generated between the coupling and the splined shaft, preventing wear and reducing damage to the splined shaft and coupling. Replacing the polyester gasket on the damaged coupling pin saves 80% of the time; traditional coupling replacement requires approximately 3 people and 8 hours, while the new coupling can be completed by 1 person in 1 hour. This disassembled coupling is applicable to the connection between the main motor and coupling in large vertical lathes, drilling machines, and mining equipment, as well as the connection between small servo motors and lead screws, showing broad application prospects.

Based on the embodiments of the present invention, it will be understood by those skilled in the art that all other embodiments obtained by making various changes, modifications, substitutions and alterations to these embodiments without departing from the principles and spirit of the present invention and without creative effort are within the scope of protection of the present invention.
