Abstract
Machine tools and other machinery and equipment are high-speed, high precision and high efficiency, large-scale development of key components such as bearings also increases the requirements. Hydrostatic bearing technology is the guarantee that with high precision and high efficiency, high load, long-life advantages of a relatively new technology, has been increasingly widely used, and achieved gratifying results.
This article discusses the type M131W bearing liquid grinding head grinding machine design modifications. The main contents are: the design of hydrostatic bearings, cutting the design, supply system design and the design of the spindle.
Hydrostatic bearings rely on the hydraulic system pressure oil supply, after cutting, and the oil into the bearing cavity, the floating shaft in bearings in the shaft to ensure that in any state and must have the load bearing friction in a fully liquid state. Thus, the relative movement in a variety of speeds, with higher load-bearing capacity; very low coefficient of friction, high rigidity, high precision turning, precision to maintain a good, long life and so on.
Hydrostatic spindle bearing system design, This article has been selected hydrostatic radial bearings, such as capillary restrictor design as the main object, and on principle. Through alterations in the cost of the case is not high, so that devices have to overcome the spindle axis is stuck to improve the performance of the machine
Keywords: Spindle Friction Hydrostatic Bearing Capillary restrictor Head design modifications
