Description

Technical Field

[0001] The utility model belongs to the technical field of detection tools, and more specifically, relates to a roller bearing size detection tool. Background Art

[0002] Roller bearings are a type of bearing widely used in various machinery and equipment. They transmit torque, support rotating shafts, and reduce friction between moving parts through rolling contact between internal rolling elements and inner and outer rings. When measuring roller bearings, vernier calipers are usually used to measure the outer diameter, inner diameter, and height of the bearing.

[0003] According to application number CN201520564285.1, a bearing measuring caliper is disclosed. The key technical solution is a bearing measuring caliper comprising a caliper body, a depth gauge rod, a vernier, and a fastening screw. A scale is engraved on the end face of the caliper body. A first measuring jaw is provided at the front end of the caliper body, and a second measuring jaw is provided on the vernier. The lower end of the second measuring jaw is configured to mate with the groove of the bearing. The second measuring jaw, integrated with the vernier, achieves high manufacturing and production accuracy. During use, the sharp first measuring jaw abuts the outer wall of the bearing before engaging the second measuring jaw in the groove. The curvature of the second measuring jaw matches that of the bearing groove being measured, ensuring a tight fit without abrasion. This improves measurement accuracy and prevents damage to the bearing's outer wall. The caliper is simple to operate, enhances measurement efficiency, and is suitable for production lines.

[0004] Based on the above, during the measurement process, the existing roller bearing size detection tool measures the outer diameter, inner diameter and height of the bearing separately, which is cumbersome to operate and affects work efficiency. Utility Model Content
