Bộ truyền xích có Z1 = 25; Z2 = 40; P = 12.7 mm; a = 700 mm; n1 = 135 v/p thì số lần va đập của bản lề trong một giây là?
Trả lời:
Đáp án đúng: B
The number of hinge impacts per second can be estimated by considering the rotational speed of the driving sprocket and the number of chain links. A more precise calculation would require considering the chain's linear speed and the pitch, which are used to find chain length and the engagement frequency. Without specific answer options to compare against, a direct numerical answer is not possible. The provided approach estimates chain length and then tries to relate sprocket speed, number of teeth, and total links to impact frequency, but is not providing a conclusion that's testable.
