Abstract

The invention discloses a device and a method for preparing a transfer lubricant film on the surfaces of ceramic balls and relates to a device and a method for preparing a lubricant coating on the surfaces of ceramic balls. The invention aims at solving the problem that the self-lubricant coating of the ceramic balls prepared by the existing method has weak bonding force and is uneven. The device comprises a first spring; the upper end of the first spring is connected with a load assembly, while the lower end therof is connected with an upper grinding disc pedestal; an upper grinding disc is arranged in the upper grinding disc pedestal and a lower grinding disc is arranged in a lower grinding disc pedestal which is connected with a rotation speed control assembly; the lower grinding disc is fixed in the lower grinding disc pedestal by four second positioning bolts; a retainer is arranged on the lower grinding disc and a plurality of round holes thereon are opposite to a V-shaped groove. The method comprises the steps: ceramic balls roll freely in the V-shaped groove and slide and grind with the upper grinding disc and the lower grinding disc; and composite materials are ground on the surface of the ceramic balls. The invention causes the surfaces of the ceramic balls to have a self-lubricant coating. The ceramic balls roll and grind between the upper grinding disc and the lower grinding disc and form a lubricant film with even thickness on the surfaces of the ceramic balls.

Description

technical field [0001] The invention relates to a device and a method for preparing a lubricating coating on the surface of a ceramic ball. Background technique [0002] Rolling bearings working in extremely harsh environments often require the use of solid lubrication. The source of the lubricant is mainly the self-lubricating material cage in the bearing. The commonly used materials for the cage are PTFE, bronze or MoS 2 Etc. When the bearing is working, the bearing ball rubs against the cage while rotating, and the cage material is used as a self-lubricating coating for the bearing ball. Existing methods for preparing self-lubricating coatings for bearing balls also include magnetron sputtering ion plating, physical vapor deposition, plasma-assisted chemical vapor deposition, electroplating, and dry film technology. However, due to the chemical inertness and non-conductivity of the ceramic material, the self-lubricating coating is prepared by the above-mentioned method o...
