As the name suggests, an open retaining ring is a retaining ring with one end not completely closed. It is a kind of retaining ring that is widely used now. Let the Haian retaining ring manufacturer introduce the definition and application of the open retaining ring to you. One, the definition of the open retaining ring The shape of the opening retaining ring is E-shaped, it is used to fix the retaining ring for zero (part) parts on the shaft, and it is suitable for the opening single ring with a nominal diameter of Du003d1.2~15MM. Second, the application example of the opening retaining ring is generally A retaining ring for fixing parts such as bearings and gears on the shaft. Fix the bearing PS on the shaft: Pay attention to the relationship between the outer diameter (D) of the collar and the shoulder diameter (Lo) of the bearing. It is necessary to meet the requirement of D. Fix the gear on the shaft and make a groove on the gear, and the groove depth is equal to the diameter of the cylindrical pin. The collar is used in conjunction with the cylindrical pin to fix the gear. PS: Pay attention to the relationship between the outer diameter (D) of the collar and the tooth root circle (df) of the gear. It is necessary to satisfy D to fix other parts on the shaft. The collar is used together with the cylindrical pin to fix the parts. 3. Design requirements of the opening retaining ring: In the design process of the opening retaining ring, the key part is the cooperation between the nominal diameter, opening and thickness of the retaining ring and the width and diameter of the groove on the shaft. Shafts with different diameters are matched with different types of collars. Design requirements, there are recommended design dimensions in the national standard GBT-896-1986-split retaining ring 'E' rings. Since the split retaining ring is already a standard part, as long as it is designed according to the standard, it is easy to buy a standard retaining ring in the market.
