Description

Technical Field

[0001] The utility model belongs to the technical field of detection tools, and in particular relates to a detection tool for detecting circular deviation of a bearing roller. Background Art

[0002] Circular deviation refers to the deviation in the radial direction on the same cross section. As one of the important technical requirements for cylindrical rollers, tapered rollers and spherical rollers, circular deviation directly determines the product quality. With the continuous improvement of the requirements for bearing accuracy, the technical requirements for rolling elements are becoming more and more stringent. Any slight error may lead to product failure. Therefore, the detection equipment for detecting circular deviation needs to be accurate and stable. At present, the circular deviation of cylindrical rollers, tapered rollers and spherical rollers is measured by placing the product on the measuring base, rotating it evenly for more than one circle, and calculating the difference between the maximum and minimum values ​​displayed on the indicator. The positioning card currently used to measure the circular deviation is an integrated design. The positioning card is used to support the rotation of the roller to measure the circular deviation.

[0003] In the actual production process, the positioning card is very easy to wear. The main reasons are: 1. The specifications of the rollers processed on each production line are similar, and the contact points on the positioning card are very close. For production lines that process rollers of the same model or rollers of similar specifications, it is easy to cause wear at the same position; 2. The contact part between the positioning card and the roller is conical, so that the contact part between the positioning card and the roller is very small; as shown in the attached figure, Figure 5 As shown in the existing integrated positioning card, both sides of the positioning card contact the rollers at the same time, and the wear caused to the positioning card is very similar, but the actual situation is not ideal, and the wear on both sides will not be consistent. The wear will affect the measurement accuracy of the circular deviation, so the positioning card needs to be replaced. However, frequent replacement of the positioning card will increase the production cost and cause waste of resources. Utility Model Content
