Two probes for P-wave are parallelly coupled in a distance on the same plane of the rock block with grease. 将两个纵波探头平行放置在同一平面,利用润滑脂耦合。
Some modifications including the improvement of bearing structure, increase of retaining ring or block, increase of lubricating grease, were made to remarkably improve work condition of bearings and improve the life of release bearings. 通过改进轴承结构、增加挡圈、加强块和增加润滑脂的注入量,可大大改善轴承的工作状态,提高分离轴承的寿命。
The structure of roller is comparatively simple. It contains many components, such as roll, bearing block, bearing, sealer, grease and axis, and so on. 托辊的结构比较简单,主要由辊筒、轴承座、轴承、密封件、润滑脂和轴等部件组成。
