Description

适用于行星齿轮传动的压力润滑油路系统Pressure lubricating oil circuit system suitable for planetary gear transmission

一、技术领域：1. Technical field:

本实用新型涉及行星机构工作过程中的机械润滑领域，适用于需要压力润滑的高速或低速重载行星机构传动压力润滑的场合，尤其适用于水平轴风力发电机组齿轮箱采用的一级NGW行星+二级平行轴传动的压力润滑油路系统。The utility model relates to the field of mechanical lubrication in the working process of a planetary mechanism, and is suitable for occasions where pressure lubrication is required for high-speed or low-speed heavy-duty planetary mechanism transmission pressure lubrication, and is especially suitable for the first-level NGW planetary+ used in the gearbox of a horizontal axis wind power generating set Two-stage parallel shaft drive pressure lubrication oil circuit system.

二、背景技术：2. Background technology:

大型风力发电机组的齿轮箱多数采用一级NGW行星+二级平行轴传动的形式，并用紧固件将各级连接在一起，可以做到尺寸小，重量轻。采用的润滑方式是：平行轴传动中的各级齿轮啮合和每个轴承，都有单独的润滑油路，采用强制方式进行润滑和冷却；行星级传动中，由于行星架的转动，行星轮与齿圈的啮合采用浸油润滑方式，行星轮与太阳轮啮合没有单独的润滑措施，安装在行星轮中的轴承，也只能采用浸油润滑的方式。这种润滑方式，会造成下列不良现象：Most of the gearboxes of large wind turbines adopt the form of one-stage NGW planetary + two-stage parallel shaft transmission, and the stages are connected together with fasteners, which can be small in size and light in weight. The lubrication method used is: in the parallel shaft transmission, the meshing of gears at all levels and each bearing has a separate lubricating oil circuit, which is lubricated and cooled in a forced way; in planetary stage transmission, due to the rotation of the planetary carrier, the planetary gear The meshing with the ring gear adopts oil-immersed lubrication method, and there is no separate lubrication measure for the meshing between the planetary gear and the sun gear, and the bearing installed in the planetary gear can only be lubricated in oil. This lubrication method will cause the following adverse phenomena:

(1)齿圈的下部浸在油中，上部远离油面，整个齿圈上各齿的润滑状态出现差异，上部轮齿不能得到良好的润滑和冷却，长期工作中造成齿面磨损不一，严重时会影响传动的平稳性。(1) The lower part of the ring gear is immersed in oil, and the upper part is far away from the oil surface. The lubrication state of each tooth on the entire ring gear is different, and the upper gear teeth cannot be well lubricated and cooled, resulting in uneven wear of the tooth surface during long-term work. In severe cases, it will affect the stability of the transmission.

(2)太阳轮与行星轮啮合润滑仅靠行星轮轮齿上粘的油完成，润滑不充分，冷却效果更差；工作时，太阳轮转速在本级中最高，原本应得到更好的润滑和冷却，现在却处于最差的状态。(2) The meshing lubrication between the sun gear and the planetary gear is completed only by the oil sticking to the gear teeth of the planetary gear, the lubrication is insufficient, and the cooling effect is even worse; when working, the speed of the sun gear is the highest in this class, which should have been better lubricated And cooling, and now it's at its worst.

(3)安装在行星轮中的轴承，随行星架转动，每转中仅有很少的时间浸在油中，润滑、冷却都不充分，特别是当在行星轮中安装由几个轴承组成的轴承组时，这种现象更加明显，影响到轴承的寿命。(3) The bearing installed in the planetary wheel rotates with the planetary carrier, and only a small amount of time is immersed in oil in each revolution, and the lubrication and cooling are not sufficient, especially when it is installed in the planetary wheel and consists of several bearings This phenomenon is more obvious when the bearing group is used, which affects the life of the bearing.

(4)齿轮箱中必须加注更多的润滑油来提高油位，实现行星轮中的轴承的浸油润滑，造成行星轮、行星架以及平行轴传动中的大齿轮浸在油面以下的深度加大，运转时，将产生较大的搅油损失和发热，降低系统的工作效率。(4) More lubricating oil must be added to the gearbox to increase the oil level to realize the oil-immersed lubrication of the bearings in the planetary gears, causing the planetary gears, planetary carriers and large gears in the parallel shaft transmission to be immersed below the oil surface When the depth is increased, it will generate a large churning loss and heat during operation, which will reduce the working efficiency of the system.

三、发明内容：3. Contents of the invention:
