Abstract
The invention discloses a novel high-speed high-rigidity angular contact ball matched bearing for a machine tool spindle, belonging to the technical field of precision machine tools. The angular contact ball matched bearing is composed of an outer ring, an inner ring, a steel ball and a retainer, wherein the bearing outer ring is at the outer end of the bearing, the bearing inner ring is at the inner end of the bearing, the steel ball serves as a bearing rolling body, is installed in the pocket of the retainer, and is kept between roller paths of the inner ring and the outer ring by the retainer, and the retainer is arranged between the inner ring and the outer ring and mainly plays a role in keeping and guiding the rolling body. The novel high-speed high-rigidity angular contact ball matched bearing is unique in structure, meets requirements of a machine tool on high speed and high rigidity, and improves the processing efficiency and precision of the machine tool.
Description
Technical fieldThe invention belongs to the precision machine tool technical field, specifically relate to be applied to the angular contact ball matched bearing of high speed, high rigidity spindle of numerical control lathe.
Background techniqueThe Capacity of Matched Angular Contact Ball Bearings of ordinary construction can't satisfy the high speed of main shaft, high rigidity requirement, causes main shaft when running up, and temperature rise, noise are too high, thereby influence the main shaft machining accuracy.
Summary of the inventionIn order to solve the defective that existing technology exists; Developed on high speed, high-precision property spindle of numerical control lathe; Be used to bear the bearing of axial force; In order to satisfy the requirement of high speed, high rigidity, preferentially select Capacity of Matched Angular Contact Ball Bearings, bearing is made up of an inner ring, outer ring, a row steel ball and an a kind of novel retainer; Because particular structure of the present invention, guaranteed lathe at a high speed, the requirement of high rigidity, improved the work efficiency and the precision of lathe.
In order to solve the problems of the technologies described above, technical solution of the present invention is: the angular contact ball matched bearing that is applied to high speed, high rigidity spindle of numerical control lathe is by the outer ring, inner ring, and steel ball, retainer is formed.Bearing outer ring is in the outer end of bearing, and bearing inner race is in the inner of bearing, and bearing roller is selected steel ball for use; Be contained in the pocket hole of retainer; Be held between the raceway that frame remains on inner ring and outer ring, retainer is located between inner ring and the outer ring, mainly plays maintenance rolling element, guiding rolling element.
1. choosing of inside and outside circle ditch curvature: adopt " equal contact stress " design principle, balance is considered the requirement of rotating speed and rigidity, chooses best ditch curvature, reaches and both satisfies the high rigidity requirement of main shaft, can effectively improve lubricatedly again, satisfies the main shaft high-speed requirement;
2. retainer structural type: " Z " type polyamide resin retainer that adopt high tenacity, light weight, has self-lubricating property;
3. adopt " single argument converter technique ", confirming influences protrusion amount key factor, accurately controls the precision transmission system spring bearing and presets the protrusion amount, guarantees that bearing operation flexibly, efficiently, accurately.
The beneficial effect that the present invention has is: structure of the present invention is unique, guaranteed lathe at a high speed, the requirement of high rigidity, improved the work efficiency and the precision of lathe.
