The connecting rods link pistons with the crankshaft and transmit to it the loads arising from the combustion gas pressure taken by the pistons. In operation, the connecting rod is subjected to both gas pressure and inertia loads, and therefore, it must be adequately strong and rigid and light in weight as well. Connecting rods are generally fabricated from a high-quality steel in the form of a bar with ring shaped heads at its ends. The heads are being known as the connecting rod big end and small end, and serv ing to attach the rod to the crankpin and the gudgeon pin of the piston respectively. 连杆将活塞与曲轴连在一起,并且向曲轴传递活塞承受 的由燃烧气体压力产生的负载。在工作时,由于连杆承受 气体压力和惯性负载,因而它必须有足够的强度和刚度, 并且质量要轻。连杆通常由优质钢加工而成,其形状为两 端成环形的棒,端头就是我们所知的连杆大头和小头,其 功用是分别将连杆与曲柄销和活塞销相连。泽邦科技 The connecting rods link pistons with the crankshaft and transmit to it the loads arising from the combustion gas pressure taken by the pistons.
