الأسطوانات الكروية

الأسطوانات الكروية

تتميز الأسطوانات الكروية بسطح كروي دائري. تتمتع المحامل ذات هذه الأسطوانات بخصائص محاذاة ذاتية ويمكنها تحمل أحمال كبيرة. تنقسم الأسطوانات الكروية إلى نوع غير متماثل وشكل متماثل، بشكل عام سطح طرفي كبير غير متماثل للسطح الكروي، وشكل متماثل لسطحي الطرفين للسطح الطرفي المسطح.

خصائص الأسطوانات الكروية

قدرة تحمل قوية للحمل: تتمتع المحامل الأسطوانية الكروية بمساحة اتصال كبيرة ويمكنها تحمل الأحمال الشعاعية الكبيرة.

احتكاك منخفض: بسبب مبدأ الاحتكاك المتدحرج، فإن المحامل الأسطوانية الكروية لديها احتكاك أقل وكفاءة أعلى من المحامل المنزلقة.

الدقة العالية: يمكن استخدام بعض الأسطوانات الكروية عالية الدقة في المعدات عالية السرعة والدقة.


عند اختيار الأسطوانة الكروية، يجب مراعاة العوامل التالية:

متطلبات التحميل: اختر المواصفات المناسبة حسب الحمل المطلوب.

متطلبات السرعة: عند الجري بسرعة عالية، اختر الأسطوانات المصنوعة من مواد مناسبة للسرعات العالية.

درجة الحرارة والبيئة: اختر المواد المناسبة وطرق الختم وفقًا لدرجة الحرارة وظروف التلوث في بيئة العمل.

التزييت: يمكن للتزييت المعقول أن يقلل الاحتكاك ويطيل عمر خدمة المحمل.
