Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, embodiment of the present invention is described further in detail.
Embodiment one
Referring to Fig. 1, a kind of steering gear rack compressing structure, have:
It is arranged on the pitch wheel in housing 7 and tooth bar 1;
Compressing the support briquetting 3 of tooth bar 1, the one end supporting briquetting 3 relative with tooth bar 1 is that face contacts arc;
Being arranged on the face supported between briquetting 3 and tooth bar 1 and contact the tabletting 2 of arc, as shown in Figure 6, the side that tabletting 2 contacts with tooth bar 1 is provided with the oil groove storing lubricant medium; Lubricant medium is lubricating oil or grease.
As shown in Figure 4, the other end that one end of support briquetting 3 contact arc is relative is provided with boss 32, and the end face of boss 32 is plane. The plane of the end face of boss 32 can as the benchmark of prototype gear and the gap width of tooth bar 1, with plane for benchmark, it is simple to measure.
As it is shown in fig. 7, compress the briquetting plug 5 supporting briquetting 3, briquetting plug 5 is threadeded with housing 7; Briquetting is compressed by briquetting plug 5.
It is arranged on briquetting plug 5 and the spring 4 supported between briquetting 3. Make support briquetting 3 at the tight tooth bar 1 of next vertical compression of support of spring 4, and in the rotation process of tooth bar 1, it is possible to allowing tooth bar 1 to produce certain displacement, compressing briquetting can move accordingly, it is prevented that after tooth bar 1 produces certain displacement, compresses the stuck situation of briquetting and occurs.
