Embodiment Construction
[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0023] Such as figure 1 with figure 2 As shown, the eccentric sleeve of the present invention has two main functions:
[0024] 1. Open the oil guide groove inside the eccentric sleeve 4, and introduce the oil flowing into the eccentric sleeve 4 from the restrictor into the hydrostatic bearing and the hydrostatic bearing chamber to provide lubricating oil for the bearing; 2. Rotate the eccentric sleeve 4 to change the dynamic and static pressure bearing The center line is used to change the center position of the spindle of the roll grinder to achieve medium-high (concave) grinding. How the eccentric sleeve 4 conducts oil and how to realize the middle and high two aspects are mainly described below.
[0025] The details are as follows:
[0026] Eccentric sleeve 4 guide oil principle:
[0027] In the grinding process of the high-speed precision roll...
