出油阀是拖汽工业的精密零件,出油阀的磨削精度直接关系到柴油机的质量与使用寿命。由于出油阀不仅加工精度要求高而且批量大,目前大都生产厂都由国外设备承担精加工。给正常生产带来种种问题。为此,上海油咀油泵厂要求我厂承担研制国产出油阀专用高精度磨床砂轮架的任务。研制出砂轮架主轴轴承是任务的关键。我们制成的偏载轴承(或称预加负载滑动轴承,具有很高的回转精度、动态特性和抗干扰能力。它适用于高效、高精度磨床的砂轮主轴
Outlet valve drag industry is the precision parts, the accuracy of the oil valve is directly related to the quality and service life of the diesel engine. As the valve not only processing requirements of high precision and large quantities, most of the production plant by the foreign equipment to undertake finishing. Bring various problems to normal production. To this end, Shanghai Oil Tsui pump factory requires that I undertake the development of domestic production of oil-fired valve for high-precision grinding wheel grinder mission. Developing a wheel spindle bearing is the key task. We made the partial load bearing (or pre-load bearing with high precision, dynamic characteristics and anti-interference ability. It is suitable for high efficiency, high-precision grinding wheel spindle
