齿轮泵在液压传动中应用较广泛,随着泵的高压、高速化,要求进一步提高其轴承的载荷能力。为此,各国除了研制高性能的轴承材料外,在改善轴承的润滑条件等方面也在深入研究。前些年,有关资料介绍了英国陶蒂公司生产的齿轮泵中采用了一种特殊的轴承低压润滑系统(简称低压润滑),引起了同行的广泛重视。如何正确理解和应用低压润滑原理进而设计出最佳方案,是十分值得共同研究的课题。以下就这方面问题作一些探讨和分析。一、陶蒂泵低压润滑系统简介图一为陶蒂(Dowty)公司专利生产的齿轮泵中采用的轴承低压润滑系统示意图。其原理是利用泵的困油腔在
Gear pump hydraulic transmission is widely used, with the pump high-pressure, high-speed, requiring further increase the bearing capacity of its load. To this end, all countries in addition to the development of high-performance bearing materials, lubrication conditions in improving the bearings are also in-depth study. A few years ago, the information on the introduction of the British Totti gear pump used in a special bearing low pressure lubrication system (referred to as low pressure lubrication), aroused widespread concern counterparts. How to correctly understand and apply the principle of low-pressure lubrication and then design the best solution is a topic worthy of joint research. The following issues on this issue for some discussion and analysis. First, the Totti Pump Low Pressure Lubrication System Profile Figure 1 is a schematic view of the low pressure lubrication system used in the gear pump manufactured by Dowty. The principle is to use the pump trapped in the oil chamber
