Description

Technical Field

[0001] The utility model belongs to the technical field of machine tool equipment, in particular to a thrust angular contact ball bearing protection structure for machine tools. Background Art

[0002] Machine tools are mechanical equipment used to perform cutting, forming, grinding or other processing operations on workpieces. They can process materials such as metals, plastics, and wood by cutting, grinding, drilling, and stamping. They are one of the most important equipment in the manufacturing industry. Machine tools are usually composed of a bed, a spindle, a feed system, a control system, and other parts. Different types of machine tools also have their own specific functions and structures. In machine tools, thrust angular contact ball bearings are usually used to support the main shaft to bear axial loads. Thrust angular contact ball bearings are a type of bearing used to bear axial loads. Thrust angular contact ball bearings can withstand axial loads from a single direction and can usually withstand light radial loads. This type of bearing is usually used to support rotating shafts, such as automobile wheels, and other applications that need to withstand unidirectional axial loads. The design of thrust angular contact ball bearings enables them to provide stable performance and low friction at high speeds. In order to ensure their normal operation and extend their service life, regular maintenance is usually required.

[0003] However, the existing maintenance method of machine tool thrust angular contact ball bearings is mostly to manually hold an oil box and drip lubricating oil into the bearing to ensure that the bearing is well lubricated and protected during operation. However, when adding oil manually, the single injection amount of oil needs to be judged manually by feel. If too much oil is injected, it is easy to cause waste. If the oil is not injected sufficiently, it will aggravate the damage to the bearing.

[0004] To this end, we provide a thrust angular contact ball bearing protection structure for machine tools to solve the above-mentioned problems. Utility Model Content
