Tóm tắt

Mục đích Các nghiên cứu trước đây chủ yếu tập trung vào việc xác định đặc điểm của con lăn mang và hiệu suất bôi trơn mà không xem xét hiện tượng trượt giữa con lăn và đường rãnh. Tuy nhiên, độ rộng của góc tròn, tải trọng, tốc độ quay và một số tham số khác có ảnh hưởng đáng kể đến tốc độ trượt giữa con lăn và đường rãnh. Bài báo này nhằm điều tra ảnh hưởng của góc tròn đến đặc tính bôi trơn giữa con lăn chịu tải nặng và đường rãnh trong điều kiện có xem xét đến hiện tượng trượt và độ nhám.
