球磨机由于使用环境恶劣,传动装置多采用封闭式承载能力大的ZD型单级减速器。但存在漏油和发热,为此进行了改进,经工业运行使用良好。 1.密封改进 ZD单级减速器漏油主要在输入和输出两轴端,原因是甩油盘与压盖止口内圈间隙过大,环形密封槽密封效果不好,当油温升高,粘度变稀后形成泄漏。原密封结构如图1。改进后将甩油盘改为配合好的啦叭形,在压盖内加了“J”型骨架密封圈,靠外压板将密封圈 Ball mill due to poor use of the environment, the use of more enclosed transmission capacity of large ZD single-stage reducer. But there is oil spill and fever, for which it has been improved and is well used by industrial operation. 1. Seal Improvement ZD single-stage reducer leakage mainly in the input and output of the two shaft ends, because the oil pan and gland stop the gap between the inner ring is too large, the annular seal groove sealing effect is not good, when the oil temperature, viscosity Leak after the formation of leakage. The original seal structure shown in Figure 1. After the improvement will be thrown off the oil pan with a good cheek, add a “J” -type skeleton ring in the gland, the outer pressure plate will seal
