What are the applications of stainless steel balls in unidirectional bearings?
In the process of one-way bearing manufacturing and assembly, after the inner and outer rings and the steel balls are combined, the steel balls need to be evenly divided into the inner and outer ring channels of the one-way bearing to facilitate the installation of the one-way bearing cage. At present, most ball-dividing devices adopt ball-dividing needle type to divide steel balls equally, and air cylinders are used to automatically divide ball-dividing needles into steel balls equally. This method is easy to damage steel balls, the cylinder is easy to produce vibration to destroy the uniform distribution of the steel ball, and it is easy to break or bend the ball needle.
many small and medium-sized enterprise one-way bearing manufacturers use manual method to divide steel balls and install cages, which is very inefficient, moreover, when installing the cage, the rubber hammer is usually used. This method can easily lead to uneven stress on both sides of the cage pocket and the Channel, reduce the clearance, and when applying force, it is not easy to control the force, it is easy to cause damage to the steel ball, the cage pocket, the channel, and the tapping assembly, the labor intensity is very large, very inconvenient.
China Patent Publication Number: CN103398110A, announces a ball splitter for a cage assembly machine. The invention relates to a ball splitter for a cage assembly machine, it comprises a handle for installation, a base and a plurality of ball dividing rods fixed on the end face of the base and distributed in an annular array, the longer one of the multiple ball-dividing rods is a ball-dividing rod, and the length of the other ball-dividing rods is reduced from one ball-dividing rod to both sides, and the rest of the ball inserts are set relative to the ball inserts.
but the tip of the ball-dividing rod of the invention is pointed, and many experiments prove that the ball-dividing rod is used to divide the ball, it is easy to cause two steel balls to be stuck between the two inserts, resulting in the failure of the ball and reducing the production efficiency. And the invention can only be divided into steel balls, can not be equipped with cages, and has a relatively single function.
