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.
See Fig. 1, a kind of steering gear rack compressing structure, has:
Be arranged on the pitch wheel in housing 7 and tooth bar 1;
Compress the support briquetting 3 of tooth bar 1, the one end supporting briquetting 3 relative with tooth bar 1 is arc;
Be arranged on the compressing tablet 2 of the arc supported between briquetting 3 and tooth bar 1, as shown in Figure 6, the side that compressing tablet 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 7, compress and support briquetting 3 gland 5, gland 5 is threaded with housing 7; Briquetting is compressed by gland 5.
The spring 4 being arranged on gland 5 and supporting 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, tooth bar 1 can be allowed to produce certain displacement, compressing briquetting can corresponding movement, after preventing tooth bar 1 from producing certain displacement, compresses the stuck situation of briquetting and occurs.
As shown in Figure 2 and Figure 5, be provided with projection in the middle part of compressing tablet 2, the one end supporting briquetting 3 arc is provided with the groove suitable with projection.Play the effect of the relative position of spacing compression briquetting and compressing tablet 2.
As shown in Figure 3, support briquetting 3 periphery and be provided with circular groove 31, in circular groove 31, be provided with rubber ring 33.Can there is deformation in rubber ring 33, in tooth bar 1 vibration processes, when compressing briquetting generation skew, can ensure that rubber ring 33 contacts with housing 7 with a certain position compressing briquetting periphery simultaneously.Compression briquetting periphery can not be made only to contact with housing 7 at a place, and produce the sharp wear caused because area of contact is little.
As shown in Figure 4, the other end that one end of support briquetting 3 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 as the benchmark of the gap width of prototype gear and tooth bar 1, can be benchmark with plane, is convenient to measure.
Gland 5 is provided with the sealing screw 6 running through gland 5, and sealing screw 6 is quality of rubber materials, dustproof and waterproof.
A technical scheme tool in technique scheme has the following advantages or beneficial effect, by the end face supporting briquetting 3 is set to the arc suitable with tooth bar 1, increase the area of contact with tooth bar 1, reduce friction, reduce the wearing and tearing of tooth bar 1, improve the service life of deflector.Compressing tablet 2 is set simultaneously, compressing tablet 2 arranges oil groove, storage lubricant medium, reduce the friction between tooth bar 1 further.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
