Embodiment Construction

[0023] Traditional lubrication methods are not suitable for the lubrication requirements of high-speed spindles, while oil-air lubrication is more suitable for the lubricating oil volume and viscosity of high-speed spindle bearings. At present, the oil-air lubrication pipeline of the electric spindle bearing of the traditional high-speed vertical machining center is a single-group lubrication method, which cannot effectively lubricate the bearing, and the heat generated by the bearing is large, and the heat generated cannot be effectively dissipated through lubrication. Affects spindle accuracy.

[0024] The present invention aims at the deficiencies in the prior art. The present invention provides an oil-air lubrication pipeline with a main shaft structure to adapt to the application of the main shaft high-speed five-axis precision vertical machining center, so that the bearing is always in the best lubrication state, and at the same time can Form a lubricating oil film with ...

Abstract

The invention discloses an oil-gas lubrication pipeline in a main shaft structure. Each group of bearings is provided with at least one group of oil inlet pipelines correspondingly, the terminal ends of each group of oil inlet pipelines are aligned to the inner rings of the bearings, each group of bearings is provided with three groups of oil inlet pipelines correspondingly, and the three groups of oil inlet pipelines form angles of 120 degrees mutually. A plurality of groups of oil inlet pipelines are correspondingly arranged on each group of bearings, and the oil inlet pipelines are uniformly distributed and arranged, so that uniform lubrication of the main shaft structure is ensured, and the heat dissipation efficiency is improved. The pipeline structure is suitable for application of a main shaft high-speed five-axis precision vertical machining center, and can effectively ensure that lubricating oil can be continuously conveyed in a small-dose and multiple-times manner, so that the bearings are always at an optimal lubrication state. Meanwhile, a lubricating oil film with certain bearing capacity can be formed, and the oil-gas lubrication pipeline has a good antifriction effect. Moreover, through oil-gas lubrication, compressed air can enable the bearings to well radiate heat, so that the bearings can be effectively cooled.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment lubrication, and in particular relates to an oil-air lubrication pipeline with a main shaft structure. Background technique [0002] The main shaft of the high-speed five-axis precision vertical machining center is directly driven by the built-in motor, so that the length of the main transmission chain of the machine tool is shortened to zero, and the main shaft components are relatively independent from the transmission system and the overall structure of the machine tool. It has a compact structure and high speed. , light weight, small inertia, fast response and high power, etc., and it is easy to realize the rapid positioning of the spindle. [0003] The spindle shoulder diameter of the vertical machining center using the BT50 spindle taper hole is large. When the spindle structure rotates at high speed, it is easy to exert periodic force on the spindle support bearing due to the e...
