Crane specific reducers include two series: QYD type and QYS type (three pivot). This reducer is mainly used for various related mechanisms of cranes, and can also be used for transmission mechanisms of mechanical equipment such as transportation, metallurgy, mining, chemical and light industry. It has a wide range of applications and the following characteristics:
High load-bearing capacity, gears are processed by carburizing, quenching, and grinding, and the load-bearing capacity is significantly improved compared to soft and medium hard tooth surface gear reducers with quenched and tempered rolling teeth.
Small in size and light in weight, compared to gear reducers with soft and medium hard tooth surfaces, reducers with the same load-bearing capacity can reduce the equivalent machine base size by 2-4.
High efficiency, low noise, and low vibration. The precision level has been improved by using gear grinding, and the gears have been trimmed. The comprehensive efficiency of each gear level is 0.98, and the vibration and noise are significantly reduced.
By using multiple levels and reducing the single-stage speed ratio, the center distance can be widened, and the overall height of the reducer can be reduced to meet the requirements of various mechanisms of the crane. The maximum nominal transmission ratio of the reducer reaches 400, which meets the requirements of slow speed cranes.
This series of reducers has a three-level combination type (i.e. a three-level assembly form and a four level transmission ratio), which provides a prerequisite for the generalization of slow speed cranes.
The three-point reducer can be installed vertically, horizontally, or even at a certain angle of deflection, making it convenient and flexible.
