Embodiment Construction

[0031] The design technology of the high-speed electric spindle rolling bearing oil-air lubrication system of the present invention will be further described in detail below in conjunction with an embodiment (the design of the high-speed electric spindle steel ball bearing 7006C and the hybrid ceramic ball bearing B7006C oil-air lubrication system).

[0032] figure 1 The specific content of the design technology of the high-speed electric spindle rolling bearing oil-air lubrication system of the present invention is given, including the following steps:

[0033] Step 1: Configuration design of oil-air lubrication system for rolling bearing of high-speed electric spindle. Such as figure 2 As shown, the air compressor 5 continuously provides compressed air, and the compressed air reaches the air storage tank 7 after passing through the three-stage filter 6 to remove impurities (dust, particles), and then passes through the cold dryer 8 to remove water vapor, and flows through ...

Abstract

The invention provides an oil-oil lubrication design method for a high-speed electric spindle rolling bearing, belonging to the technical field of rolling bearing cooling and lubrication. The design technology includes the following steps: 1, the configuration design of the oil-gas lubrication system of the high-speed electric spindle rolling bearing; 2, structural design of the oil-gas nozzle ofthe high-speed rolling bear; 3, designing the oil and gas parameters of the high-speed roll bearing. The design technology puts forward a basic configuration scheme of oil-air lubrication system, andprovides a technical method for structural design of oil-air nozzle and selection of oil-air parameters. The oil-oil lubrication design technology of the high-speed electric spindle rolling bearing provided by the invention can effectively improve the lubrication effect of the oil-oil lubrication system of the high-speed electric spindle rolling bearing, greatly reduce the working temperature riseof the high-speed electric spindle rolling bearing, and prolong the service life of the high-speed electric spindle rolling bearing.

Description

technical field [0001] The invention relates to an oil-air lubrication design method for a rolling bearing of a high-speed electric spindle, which belongs to the design field of the spindle unit of a high-speed machining machine tool. Background technique [0002] The high-speed electric spindle is the core functional component of the high-speed machining machine tool, and the performance of the electric spindle determines the overall performance of the machine tool to a large extent. With the development of high-speed machining, the speed of high-speed electric spindle continues to increase, and the calorific value of rolling bearings rises sharply, which puts forward higher requirements for the cooling and lubrication technology of rolling bearings. Traditional bearing lubrication methods (oil circulation lubrication, grease lubrication, oil spray lubrication, oil mist lubrication) can no longer meet the needs of high-speed electric spindle bearings. Oil-air lubrication t...
