我单位一台YZ14JC型振动压路机,新机在工作了100h左右后出现了整机抖动的现象。不开振动时,机器行走工作正常;每天工作的前1h左右抖动现象不明显,之后抖动加剧且发动机转速有所下降;如果停机1h后重新启动工作时,抖动现象有所好转。 该机动力为4135AK-4型柴油机。液压系统配备进口液压双联齿轮泵和液压马达。 分析整机抖动的原因,可能是振动钢轮内部轴承或振动偏心块出现了问题。拆检表明:振动偏心块转动正常,无卡滞现象,轴承完好无损。当将振动马达接上液压油管但不带动振动偏心块
I unit a YZ14JC Vibratory Road Roller, the new machine after working for about 100h appeared jitter phenomenon. Not open the vibration, the machine is working properly; daily work before about 1h jitter is not obvious, then increased jitter and engine speed decreased; if the shutdown after 1h restart work, the jitter has been improved. The power of 4135AK-4 diesel engine. Hydraulic system is equipped with imported hydraulic double gear pump and hydraulic motor. Analysis of the reasons for the whole machine jitter, vibration steel drum may be the internal bearing or vibration eccentric block problems. Demolition inspection shows: vibration eccentric block rotation normal, no card stagnation phenomenon, the bearing intact. When the vibration motor connected to the hydraulic tubing but does not bring vibration eccentric block
