铣刨转子边刀及边刀座磨损原因分析及改进

铣刨转子是铣刨机的核心部件，其边刀及边刀座的快速磨损会影响到铣刨机的正常工作，介绍铣刨转子的结构组成和特点。从边刀的侧倾角和外倾角的设计、立刀对边刀的保护，以及废料的抛送对铣刀的磨损、铣刨深度和最大行走速度的合理匹配等方面分析造成磨损的原因，并对边刀的侧倾角、外倾角和切入角以及抛料板的结构进行改进设计，重新布置铣刨转子两侧的铣刀。改进后的铣刨转子在实际施工使用中效果良好。

Causes Analysis of Wear on Side Cutters and Side Cutter Seats of a Milling Rotor as well as Their Improvement

The milling rotor is the core part for a milling machine. Rapid wear on side cutters and their seats will influence proper operation of the machine. Structural construction and characteristics of a milling rotor are described. Causes of wear are analyzed from the aspects of sidetilting-angle and outside tilting-angle design, vertical cutter protection for side cutter, milling cutters wear due to spoil rejecting as well as rational match between milling depth and maximum travel speed. Improvement designs are...
