挖掘机在定点装载或作业空间受限制时,其回转制动功能显得特别重要,现结合我们使用的机型,将挖掘机几种主要制动装置介绍如下。1.自锁式回转制动装置自锁式回转制动常采用液压马达带动蜗杆驱动蜗轮实现回转制动。蜗杆蜗轮传动具有自锁性,当马达不转时,回转能立即停止。这种制动方式具有传动 When the fixed-point loading or working space is limited, the rotary braking function of the excavator is of special importance. Now we combine the models we used to introduce the main braking devices of the excavator as follows. 1. Self-locking rotary brake Self-locking rotary brake often driven by a hydraulic motor worm drive worm to achieve rotary braking. Worm gear transmission with self-locking, when the motor does not turn, the rotation can stop immediately. This braking mode with transmission
