黑龙江省宝清县853农场5分场修配所读者孙东同志来信询问,原苏联产ДT-75型履带式拖拉机在使用中经常出现不转向故障是什么原因造成的。我们认为,这很可能是由于行星机构制动带与制动鼓锈粘而引起的。为什么行星机构制动带与制动鼓锈粘在一起就会使拖拉机不转向呢?正巧,我们手头上有一篇文章,其中介绍了这种类型拖拉机转向机构的构造和作用原理,仔细读一读就能明白这个问题,现将该文刊出。顺便说一句,对于这种类型的拖拉机,应当采取一些措施来预防上述故障的产生。例如,当拖拉机长期停放时应松退行星机构制动器调整螺母。再如,停放期间,应定期使行星机构制动带与制动鼓之间产生相对运动,这可以用以下方法来达到:挂上Ⅰ档,把两侧的操向杆都拉到适当位置,然后播转曲轴。当然,也可能有其他原因导致产生这一故障现象,欢迎有经验的同志来信来稿加以阐述。
Heilongjiang Province, Baoqing 853 Farm 5 points match with the reader Sun Dong comrades from the letter asked, the original Soviet-made Caterpillar-type crawler tractor in use often does not turn to the fault is what causes. In our opinion, this is most likely caused by rusting of brake linings on the brake linings of planetary gears. Why do the planets’ brake bands and brake drum rust stick together to keep the tractor from turning? Occasionally, we have an article on hand that describes the construction and functioning of this type of tractor steering mechanism and reads it carefully Will be able to understand this problem, now the article published. Incidentally, with this type of tractor, some measures should be taken to prevent the above-mentioned failure. For example, when the tractor is parked for a long time, the planetary mechanism brake adjusting nut should be loosened. Again, during parking, the planetary gear should be regularly made with the drum brake drum relative movement, which can be achieved by the following methods: I hang up the file, the two sides of the steering rod are pulled to the appropriate position, Then broadcast crankshaft. Of course, there may be other reasons that may lead to this phenomenon. We welcome comments from experienced comrades in letters and letters.
