Pendekatan Analitis untuk Memperkirakan Tekanan Kontak pada Sambungan Spline
A spline coupling is a type of mechanical connection between two rotating shafts. It consists of two parts – a coupler and a coupling. Both parts have teeth which engage and transfer loads. However, spline couplings are typically over-dimensioned, which makes them susceptible to fatigue and static behavior. Wear phenomena can also cause the coupling to fail. For this reason, proper spline coupling design is essential for achieving optimum performance.
Pemodelan kopling spline
Sambungan spline semakin populer di industri kedirgantaraan, tetapi sambungan ini beroperasi dalam kondisi sedikit tidak sejajar, yang menyebabkan getaran dan kerusakan pada permukaan kontak. Untuk mengatasi masalah ini, artikel ini menawarkan pendekatan analitis untuk memperkirakan tekanan kontak pada sambungan spline. Secara khusus, artikel ini membandingkan pendekatan analitis dengan pendekatan numerik murni untuk menunjukkan manfaat dari pendekatan analitis.
To model a spline coupling, first you create the knowledge base for the spline coupling. The knowledge base includes a large number of possible specification values, which are related to each other. If you modify one specification, it may lead to a warning for violating another. To make the design valid, you must create a spline coupling model that meets the specified specification values.
After you have modeled the geometry, you must enter the contact pressures of the two spline couplings. Then, you need to determine the position of the pitch circle of the spline. In Figure 2, the centre of the male coupling is superposed to that of the female spline. Then, you need to make sure that the alignment meshing distance of the two splines is the same.
Once you have the data you need to create a spline coupling model, you can begin by entering the specifications for the interface design. Once you have this data, you need to choose whether to optimize the internal spline or the external spline. You’ll also need to specify the tooth friction coefficient, which is used to determine the stresses in the spline coupling model 20. You should also enter the pilot clearance, which is the clearance between the tip 186 of a tooth 32 on one spline and the feature on the mating spline.
After you have entered the desired specifications for the external spline, you can enter the parameters for the internal spline. For example, you can enter the outer diameter limit 154 of the major snap 54 and the minor snap 56 of the internal spline. The values of these parameters are displayed in color-coded boxes on the Spline Inputs and Configuration GUI screen 80. Once the parameters are entered, you’ll be presented with a geometric representation of the spline coupling model 20.
Membuat model kopling spline 20
The spline coupling model 20 is created by a product model software program 10. The software validates the spline coupling model against a knowledge base of configuration-dependent specification constraints and relationships. This report is then input to the ANSYS stress analyzer program. It lists the spline coupling model 20’s geometric configurations and specification values for each feature. The spline coupling model 20 is automatically recreated every time the configuration or performance specifications of the spline coupling model 20 are modified.
Model sambungan spline 20 dapat dikonfigurasi menggunakan program perangkat lunak model produk 10. Pengguna menentukan panjang aksial tumpukan spline, yang dapat berupa nol, atau panjang tetap. Pengguna juga memasukkan permukaan kontak radial 148, jika ada, dan memilih nilai spesifikasi jarak bebas pilot sebesar 14,5 derajat atau 30 derajat.
Pengguna kemudian dapat menggunakan mouse 110 untuk memodifikasi model kopling spline 20. Basis pengetahuan kopling spline berisi sejumlah besar nilai spesifikasi yang mungkin dan aturan desain kopling spline. Jika pengguna mencoba mengubah model kopling spline, model tersebut akan menampilkan peringatan tentang pelanggaran spesifikasi lain. Dalam beberapa kasus, modifikasi tersebut dapat membatalkan desain.
In the spline coupling model 20, the user enters additional performance requirement specifications. The user chooses the locations where maximum torque is transferred for the internal and external splines 38 and 40. The maximum torque transfer location is determined by the attachment configuration of the hardware to the shafts. Once this is selected, the user can click “Next” to save the model. A preview of the spline coupling model 20 is displayed.
Model 20 merupakan representasi dari sambungan spline. Spesifikasi spline dimasukkan sesuai urutan dan susunan yang ditentukan pada layar GUI model sambungan spline 20. Setelah spesifikasi sambungan spline dimasukkan, program perangkat lunak model produk 10 akan menggabungkannya ke dalam model sambungan spline 20. Ini adalah langkah terakhir dalam pembuatan model sambungan spline.
Menganalisis model kopling spline 20
Analisis model sambungan spline terdiri dari memasukkan konfigurasi dan spesifikasi kinerjanya. Spesifikasi ini dapat dihasilkan dari program komputer lain. Program perangkat lunak model produk 10 kemudian menggunakan basis pengetahuan internalnya tentang hubungan dan batasan spesifikasi yang bergantung pada konfigurasi untuk membuat model parametrik tiga dimensi yang valid 20. Model ini berisi informasi yang menjelaskan jumlah dan jenis gigi spline 32, pengait 34, dan bahu 36.
Saat Anda menganalisis sambungan spline, program perangkat lunak 10 akan menyertakan nilai default untuk berbagai spesifikasi. Model sambungan spline 20 terdiri dari spline internal 38 dan spline eksternal 40. Masing-masing spline memiliki serangkaian parameternya sendiri, seperti kedalaman, lebar, panjang, dan jari-jari. Spline eksternal 40 juga akan berisi serangkaian parameternya sendiri, seperti orientasinya.
Setelah memilih parameter-parameter ini, program perangkat lunak akan melakukan berbagai analisis pada model kopling spline 20. Program perangkat lunak 10 menghitung tegangan bantalan gigi nominal dan maksimal serta umur kelelahan kopling spline. Program ini juga akan menentukan perbedaan puntiran torsi antara spline internal dan eksternal. File keluaran dari analisis akan berupa file laporan yang berisi konfigurasi model dan data spesifikasi. File keluaran ini juga dapat digunakan oleh program komputer lain untuk analisis lebih lanjut.
Once these parameters are set, the user enters the design criteria for the spline coupling model 20. In this step, the user specifies the locations of maximum torque transfer for both the external and internal spline 38. The maximum torque transfer location depends on the configuration of the hardware attached to the shafts. The user may enter up to four different performance requirement specifications for each spline.
The results of the analysis show that there are two phases of spline coupling. The first phase shows a large increase in stress and vibration. The second phase shows a decline in both stress and vibration levels. The third stage shows a constant meshing force between 300N and 320N. This behavior continues for a longer period of time, until the final stage engages with the surface.
Ketidaksejajaran sambungan spline
A study aimed to investigate the position of the resultant contact force in a spline coupling engaging teeth under a steady torque and rotating misalignment. The study used numerical methods based on Finite Element Method (FEM) models. It produced numerical results for nominal conditions and parallel offset misalignment. The study considered two levels of misalignment – 0.02 mm and 0.08 mm – with different loading levels.
Hasil penelitian menunjukkan bahwa ketidaksejajaran antara spline dan rotor menyebabkan perubahan gaya gesekan pada sistem kopling spline-rotor. Dinamikanya diatur oleh gaya gesekan spline. Gaya gesekan pada kopling spline yang tidak sejajar berhubungan dengan parameter sistem kopling rotor-spline, torsi transmisi, dan perpindahan getaran dinamis.
Meskipun kurangnya pengukuran yang tepat, ketidaksejajaran spline merupakan masalah umum. Masalah ini diperparah oleh fakta bahwa spline biasanya memiliki celah (backlash). Celah ini merupakan hasil dari ketidaksejajaran spline. Para penulis menganalisis beberapa spline, dengan memvariasikan diameter pitch, dan rasio panjang/diameter.
Kopling spline adalah sistem mekanis dua dimensi yang memiliki celah positif. Kopling spline terdiri dari hub dan poros, dan memiliki celah ujung-ke-akar yang lebih besar daripada celah tersebut. Celah bentuk cukup untuk mencegah kontak fillet ujung-ke-akar. Torsi pada spline ditransmisikan melalui gesekan.
Ketika sambungan spline tidak sejajar, gaya dorong yang cenderung torsi akan dihasilkan. Dalam situasi seperti itu, gaya dapat melebihi torsi, menyebabkan komponen kehilangan kesejajarannya. Transmisi dua arah torsi dan dorong dimodelkan secara analitis dalam penelitian ini. Pendekatan analitis memberikan solusi yang dapat diintegrasikan ke dalam proses desain. Jadi, lain kali Anda menghadapi masalah sambungan spline yang tidak sejajar, pastikan untuk menggunakan pendekatan analitis!
Dalam penelitian ini, sambungan spline dianalisis dalam kondisi nominal tanpa ketidaksejajaran offset paralel. Nilai kekakuan yang diperoleh adalah perbedaan persentase antara diameter pitch nominal dan diameter aplikasi beban. Selain itu, perbedaan persentase maksimum pada diameter pitch terukur adalah 1,60% pada torsi 5000 N*m. Parameter lainnya, yaitu sudut pitch, juga diperhitungkan dalam perhitungan.
