本文对压路机的轴的强度进行了新的设计,同时也选用了新的轴承并对其寿命作了校核。在整个后轮系统设计中对轮胎选择、动力传动过程中所用到的链条链轮的设计同样重要

[摘要]:近年来我国交通建设发展日益加快,对路面的质量要求也越来越高,传统的压路机压实不均匀的弊端要求着一种新型压路机来替代。大吨位轮胎压路机在这种情况下应孕运而生。YL25型轮胎压路机是我国目前一种吨位较大的轮胎压路机,从市场需求来看日后的市场发展是可期待的。该压路机可以对一切路面工作。国外对轮胎压路机技术上的投资远远高于我国,这也是我国计算落后的一个重要方面。但随着这几年对国外先进技术的引进和资金的投入以及对轮胎压路机系列产品的发展,使得我国压路机在国际市场上也占有一定的比例。31940
YL25型轮胎压路机是采用后轮驱动这就让后轮系统设计显得尤为重要,本文根据相关文献提供的资料了解到压路机的故障多发生的是轴的强度不够。所以本文对压路机的轴的强度进行了新的设计,同时也选用了新的轴承并对其寿命作了校核。在整个后轮系统设计中对轮胎选择、动力传动过程中所用到的链条链轮的设计同样重要。针对后轮的差速器、驱动半轴与制动器本文也进行了详细的设计。最后,论文对各主要配件的厂家选择安装尺寸作了一般性的阐述。

YL25 type pneumatic tyre roller wheel system design
[Abstract]:In recent years the development of traffic construction in our country grows ever faster, large tonnage tire roller compaction effect is more and more users get the recognition. YL25 type tire roller as China's current large tonnage tire rollers, has a vast market prospects and market demand. The roller can work to all roads. Foreign investment in the tyre roller technology is much higher than our country, it is also an important aspect of our country's calculation behind. But as the past few years the introduction of foreign advanced technology and products for tire roller development, making China the roller on the international market has a certain proportion.

YL25 type tire roller is rear-wheel drive system which allows the rear wheel design is particularly important, this paper based on the information provided by the relevant literature occurred roller failures are learned enough strength of the shaft. Therefore, this paper on the strength of roller shaft for a new design, but also the choice of a new bearing and its life were checked. Throughout the rear tire choice for system design, power transmission chain sprocket design used in the process is equally important. For the rear differential, drive axle and brake paper also carried out a detailed design. Finally, the paper summarizes the major parts manufacturers choose to install size made a general exposition.
