却贝尔载重汽车汽车转向很沉重,尤其在土方工地上使用,转向更是困难。我们在修车中,把转向器中的转向蜗轮结构做了改进,大大提高了汽车的转向灵活性,受到了用户的好评。却贝尔汽车转向器是球面蜗杆双滚轮式,速比为23.5:1,滚轮内有两排滚针轴承,在滚轮轴套上滚动,滚轮两侧在止推垫片上滑动。这种转向器滑动磨擦阻力很大,传动效率较低。这种转向器滚轮与两侧的止推垫片之间的磨擦损失占总损失的一半以上,蜗杆和蜗轮接触磨擦损失和蜗杆两端的锥形滚柱止推轴承的磨擦损失也各占总损失的五分之一。可见由于结构的问题和修配工艺上的问题,却贝尔车比
However, Bell truck heavy car steering, especially in earthmoving, steering is more difficult. We repair the car, the steering gear in the steering wheel structure has been improved, greatly improving the steering flexibility of the car, has been praised by users. However, the Bell steering system is a spherical worm dual-wheel type with a speed ratio of 23.5: 1. There are two rows of needle roller bearings in the roller, which roll on the roller sleeve. Both sides of the roller slide on the thrust washer. This steering sliding frictional resistance, transmission efficiency is low. The friction loss between the steering wheel and the thrust washers on both sides accounts for more than half of the total loss, the contact friction loss between the worm and the worm wheel and the friction losses of the tapered roller thrust bearings at the two ends of the worm also each take the total loss One-fifth of the Visible due to the structural problems and repair process on the issue, but Bell car than
