Meanwhile, the rolling bodies are fixed in the pockets of the retainer by the retainer, so that the rolling bodies are convenient to install, and damage to the rolling bodies in the installation process is reduced.
The purpose of the utility model is realized in the following way:
the utility model provides a high-speed silence low angular contact ball bearing holder that generates heat, includes the holder body, the circumference equipartition of holder body has a plurality of pockets, the pocket is drum-shaped, and the pocket corresponds the rolling element and is equipped with the arc contact surface, and every pocket is equipped with radial outer flaring and radial inner locking notch, radial outer flaring sets up the outer end at the pocket, radial inner locking notch sets up the inner at the pocket, radial inner locking notch diameter is less than radial outer flaring, and the rolling element is impressed the pocket from radial outer flaring.
Preferably, the pocket hole is formed by integrating an outer pocket groove and an inner pocket groove, and the outer pocket groove and the inner pocket groove are U-shaped and have opposite opening directions.
Preferably, the outer pocket opening is upward, two side walls of the outer pocket extend to the upper end face of the retainer body, the inner pocket opening is downward, and two side walls of the inner pocket extend to the lower end face of the retainer body.
Preferably, the radially outer flaring is located at the outer end of the outer pocket and the radially inner locking notch is located at the inner end of the inner pocket.
The beneficial effects of the utility model are as follows:
according to the utility model, the inner wall of the pocket hole is in a drum-shaped structure, the storage area of lubricating grease in the retainer is increased by the arc-shaped contact surface, more lubricating grease can be conveniently stored in the retainer, the lubricating condition of the rolling body can be improved, the temperature of the bearing is reduced, and the slight deformation of the retainer body is reduced;
the two ends of the pocket hole are arranged into the structures with large outside and small inside, the rolling bodies can only be pressed into the pocket hole from outside to inside along the radial direction, the rolling bodies are reduced to float, noise is avoided in the high-speed operation process, meanwhile, the installation of the rolling bodies is facilitated, and damage to the rolling bodies in the installation process is reduced.
