L25型轮胎压路机前轮系统设计[关键词]: YL25;轮胎压路机;前轮;挡泥板;转向机构[摘要]:在建造公路、铁路以及其他大型建筑时,压路机已经成为必不可少的工业设备。轮胎压路机比钢轮式压路机要灵活,另外,轮胎压路机有柔性压实的附加功能,从这一点看,其它压实设备不能办到。所以研究轮胎压路机具有重要的意义。32655
本次设计为YL25型轮胎压路机的前轮设计,要在满足既定压路机整体参数要求的前提下,完成相应的前轮的设计以及优化。包括前轮主轴的设计、轮胎的选型、前轮立轴的设计以及转向系统的设计等。32655
在该设计中计算出了相关零件的力学数据以及零件寿命等问题,完成了相应零件的选型。各零件的装配问题在附录的装配图纸中均有体现。
前轮的立柱、挡泥板以及转向机构均设计在摇摆件上,保证整体的一致性。论文网
轮胎压路机的前轮承担了压路机近一半的重量,前轮的安全性与稳定性是压路机进行工作的前提,前轮的设计就有很大的必要。
 The Design of Front Wheels for The YL25 Pneumatic Tyred Roller
[Keyword]:YL25 ;pneumatic tyred roller ;front wheel;splash guard;splash guard
[Abstract]:Now rollers have become the indispensable industrial equipment when building roads , railways and other large buildings . Pneumatic tyre roller is much more flexible than steel wheel roller , and pneumatic tyre roller has irreplaceable function of soft compaction than other compaction equipment . SO it’s of great significance to study the Pneumatic tyre roller .
This design is for type YL25 tyre roller front wheels . It must be right to the univers parameter that have known ,and the total design of the front wheels. Including the design of the front wheel spindle, the selection of the tire , the design of the vertical shaft of front wheels and the design of the steering system. 源自!六%维^论*文`网www.lwfree.cn
In this manual, the mechanical data of related parts as well as the life span of machinery parts are calculated, and every component of the system has been designed. Their assemble can be seen in the assembly drawing. The vertical shaft of front wheels, the splash guard and the knuckle mechanic are all designed on the swing part, so that the system can be much more perfect.
The front wheels of the roller bear almost half of weight of the roller, so the security and stability of the front wheel is the precondition of the roller’s work, and the design of the front wheel has great significance to the whole roller.
