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.

Step one: be set to by bearing holder (housing, cover) on the bearing seat step that matches with its internal diameter, bottom is supported by adjacent step, holds with hand push last item, whether can the sequence of sanqu songs within a particular musical mode, if there is the sequence of sanqu songs within a particular musical mode, then this bearing is scrapped if detecting bearing;
Step 2: open motor, detect through the dirigibility of step one non-sequence of sanqu songs within a particular musical mode bearing rotary, rotate dumb if occur, then this bearing is scrapped;
Step 3: disable motor, injects the bearing detecting flexible rotation through step 2 by lubricating grease uniform with syringe, open motor, and bearing seat rotates 1 ~ 2min with the speed of 100 ~ 200 revs/min, and disable motor, even fat process terminates.
Beneficial effect of the present invention:
The device detected for bearing oil homogenized and flexibility of revolution provided by the invention, detect bearing rotary dirigibility and sequence of sanqu songs within a particular musical mode situation before bearing grease injection, after can avoiding occurring filling out fat, the even fat process centre bearer sequence of sanqu songs within a particular musical mode, causes the waste of time and the means of production; Multiple steps of stepped appearance bearing seat go for the bearing of multiple different inner diameters size, highly versatile; And stepped appearance bearing seat is firmly steady, particularly larger axis holds or less bearing, only need adopt relative step, well can complete greasing and even fat process; The even fat of multi-turn number can be completed after bearing grease injection within very short time, ensure that the railway grease of bearing is all uniformly distributed in bearing channel; This device is simple to operation, alleviates labor strength, substantially increases work efficiency;
Even fat provided by the invention and detection method simplify even fat process, and meet again the detection of bearing rotary dirigibility and the detection of the whether sequence of sanqu songs within a particular musical mode, substantially increase efficiency of assembling, saved manpower, easy to operate, device is simple and easy, with low cost simultaneously.
