A device and method for bearing grease uniformity and rotation flexibility detection

Abstract

The invention relates to a device for detecting bearing grease uniformity and rotation flexibility and a method. The device comprises a motor whose spindle is vertically arranged and a bearing block for fixing the bearing. Before bearing grease injection, the bearing rotation flexibility and a sleeve loosening condition are detected, bearing sleeve loosening during a grease uniformity process after grease filling can be avoided, and waste of time and production materials can be avoided. Multiple steps of a step-shaped bearing block can be applied to bearings with multiple different inner diameter sizes, and generality is strong. The step-shaped bearing block is firm and stable, and particularly for a large bearing or a small bearing, as long as a corresponding step is adopted, grease injection and grease uniformity processes can be well done. After bearing grease injection, multiple turns of grease uniformity are completed in a short time period, the grease of the bearing can be ensured to be uniformly distributed in a bearing channel. The device is simple and easy to operate, the labor intensity of workers is lessened, and the working efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of bearing detection and assembly, in particular to a device and method for simultaneously completing bearing grease uniformity and rotation flexibility detection. Background technique [0002] At present, most high-precision angular contact ball bearings in China are still produced in small batches and with multiple varieties. The status and disadvantages of the grease injection process and quality inspection of the bearings are as follows: [0003] 1. There is no detection of bearing rotation flexibility and loose sleeves before bearing grease filling, and the loose sleeves and rotation flexibility of bearings in the process of uniform grease after grease filling are often unqualified, resulting in waste of time and production materials; [0004] 2. At present, the grease injection and uniform grease are manually operated. Hold the bearing in one hand and inject grease with the syringe in the other hand, a...

Problems solved by technology

[0003] 1. There is no detection of bearing rotation flexibility and loose sleeves before bearing grease filling, and the loose sleeves and rotation flexibility of bearings in the process of uniform grease after grease filling are often unqualified, resulting in waste of time and production materials;

[0004] 2. At present, the grease injection and uniform grease are manually operated. Hold the bearing in one hand and inject grease with the syringe in the other hand, and then rotate the inner ring with your fingers to even grease. If it is a large bearing or a small bearing, the grease injection and uniform grease cannot be well completed. Lipid process;

[0005] 3. Rotate the inner ring with your fingers to evenly grease the bearing after grease injection. Due to the small number of rotations and low speed, this method cannot ensure that the grease in the bearing is evenly distributed in the groove;

[0006] 4. Completely manual operation, high labor intensity and low work efficiency
