Detailed Description
In order to make the structure and function of the present invention clearer, the drawings in the embodiments of the present invention are combined below to clearly and completely describe the technical solution in the embodiments of the present invention.
Referring to the attached drawing 1, the ball bearing locking type retainer comprises a retainer body 1, pockets 5 for containing steel balls 4 are formed in the retainer body 1, a connecting section 6 is arranged between every two adjacent pockets 5, and a limiting surface matched with a bearing inner ring channel for positioning is arranged on the inner wall of each connecting section 6.
Based on the technical scheme, the limiting surface is arranged on the connecting section and located between the two pockets, the limiting surface is located between the two steel balls during assembly, and when the limiting surface is matched and located with the bearing inner ring channel, the guiding and rolling of the steel balls and the bearing inner ring channel are not affected.
Furthermore, the limiting surface is an inclined surface matched with the flange of the bearing inner ring channel, and the inclination angle of the inclined surface is 15 degrees.
Furthermore, the inner wall of the connecting section 6 is provided with a flange 7, and the side plane of the flange 7 forms a limit surface which is matched and positioned with the flange of the bearing inner ring channel.
Preferably, the height of the flange 7 is 0.2mm, that is, in the positional relationship of fig. 1, the flange 7 is 0.2mm lower than the rib of the bearing inner ring groove, and the inclination angle of the limiting surface of the flange 7 is 15 °.
Furthermore, the flange 7 is arranged along an arc shape on the inner wall of the connecting section, and the radian of the flange 7 is matched with that of the flange of the bearing inner ring channel.
Furthermore, the pocket 5 is spindle-shaped, and the steel ball 4 and the pocket 5 are in point contact, so that the friction resistance is reduced.
Furthermore, an inwards concave weight reduction groove 8 is formed in the end face, away from the pocket opening, of the connecting section 6, and the weight reduction groove 8 is arranged in an arc shape.
Further, the bottom of the lightening groove 8 is provided with a communication hole 9 penetrating through the connecting section.
Based on above-mentioned technical scheme, the holder terminal surface adopts digs arc groove structure to link up from the centre, can reduce holder weight on the one hand, reduce the centrifugal force effect, on the other hand can be favorable to lubricating grease to get into inside steel ball and the raceway, more be favorable to the lubrication.
Furthermore, an annular groove 10 is formed in the end face, provided with the pocket, of the retainer body 1, the annular groove 10 is located between the inner wall and the outer wall of the retainer and coaxial with the retainer, and the plurality of communication holes 9 are communicated with the annular groove 10.
