Abstract
The utility model discloses an assembly of an oil seal frame and a retaining ring with a needle roller, applying to a needle roller bearing. The utility model comprises an oil seal frame and an oil seal made of rubber piece. A retaining rib which is with an angle and can prevent the needle roller form rolling back is arranged on the joint of the oil seal frame and the needle roller bearing. The oil seal frame is integrated with the retaining ring with a needle roller in the utility model so that the efficient contact area of the needle roller inside the bearing is increased and the abrasion service life of the product is improved. The utility model has simple structure, convenient installation and strong practicability.
Description
Technical field
The utility model relates to oil tight skeleton and the needle roller back-up ring assembly parts that is used for needle bearing.
Background technique
Traditional needle bearing design, oil tight skeleton as shown in Figure 4, do not design a punching press rib on the oil tight skeleton, make needle roller unfixing in bearing, be prone to the phenomenon of falling the pin, the method for head it off is to increase a needle roller back-up ring as shown in Figure 3 in bearing usually, oil tight skeleton and needle roller back-up ring are two independently parts, make bearing parts various, assembling is complicated, and manufacture cost is also higher relatively.
Summary of the invention
The purpose of this utility model provides a kind of oil tight skeleton and needle roller back-up ring assembly parts that is used for needle bearing.
It has the oil sealing of oil tight skeleton, rubber parts composition, is provided with the punching press rib at oil tight skeleton and needle bearing connecting part.
The utility model is designed to one with oil tight skeleton and needle roller back-up ring, reasonable in theory, and it is feasible through evidence, can reduce part takes up space, then can respond lengthening needle roller length, make effective surface of contact increase of needle roller in the bearing, improved the wear-out life of product, simple in structure, easy for installation, practical.
