我国第一台1.2m防爆液压绞车,采用了内曲线液压马达驱动,这种液压马达性能良好,是防爆液压绞车的关键部件。而液压马达的导轨又是液压马达的关键零件,其质量好坏直接影响液压马达的性能和寿命,在导轨的磨削加工过程中稍有疏忽,就会产生磨削裂纹而成为废品。因此,防止磨削裂纹是生产液压马达导轨的一个重要环节,不可忽视。 China’s first 1.2m explosion-proof hydraulic winch, used within the curve hydraulic motor drive, this hydraulic motor performance is good, is a key component of the hydraulic explosion-proof winch. The hydraulic motor guide rail hydraulic motor is the key components, the quality of a direct impact on the performance of hydraulic motors and life expectancy in the rail grinding process slightly negligent, it will produce grinding cracks and become waste. Therefore, to prevent grinding cracks is the production of hydraulic motor guide rail an important part, can not be ignored.
