Abstract
A holding rack for a four-point contact ball bearing with a two-piece outer ring comprises a holding rack seat and a holding rack end cover, wherein the holding rack end cover is arranged at the upper end of the holding rack seat, and the holding rack end cover and the holding rack seat are fixedly connected. The holding rack has the technical points that a plurality of pockets are processed on one side surface of the holding rack seat; a lug boss is processed in the middle external diameter or the middle internal diameter of each pocket of the holding rack seat, so as to lock a steel ball; a lug boss suitable for a QJF ball bearing is processed in the middle external diameter of each pocket of the holding rack seat or a lug boss suitable for a QJ ball bearing is processed in the middle internal diameter of each pocket of the holding rack seat; the steel ball is mounted in each pocket from the side surface; the holding rack end cover and the holding rack seat are fixed together; and the holding rack is guided by the steel balls. The utility model has the advantages that the locking effect to the steel balls is good; the ball falling phenomenon is avoided, inspection and repair time is saved, and the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of bearing retainer, specifically is a kind of four-point contact ball retainer.
Background technique
Four-point contact ball (QJ and QJF type) is mainly used in and bears the bi-directional axial load, and makes the usefulness of main shaft axially locating.With the supporting use of four-line column roller bearing, be widely used on the rolling machinery.This retainer is designed to entity structure usually, and goes up cutter mouthful lock ball at retainer internal diameter (or external diameter).Proof is used in installation, and the phenomenon of ball in use often appears falling because of the wearing and tearing of lock ball mouth in this bearing, brings inconvenience to user's installation.
The model utility content
The purpose of this utility model provides a kind of double semi outer rings four-point contact ball retainer of avoiding occurring falling the ball problem.
Known QJ type ball bearing is guided by outer casing internal diameter, and QJF type ball bearing is guided by interior cover external diameter, and steel ball is gone up cutter mouthful lock ball at retainer internal diameter (QJ type) or external diameter (QJF type) after putting into the pocket hole, and figure two is QJF type retainer lock ball schematic representation.The shortcoming of this retainer is hold depth wearing and tearing in use for some time, often falls the phenomenon of ball during the dismounting bearing.
The technological scheme that adopts is:
A kind of double semi outer rings four-point contact ball retainer, comprise and keep stand, retainer end cap, the retainer end cap is arranged on and keeps the stand upper end, the retainer end cap is fixedlyed connected with keeping stand, its technological points is to keep a side of stand to process a plurality of pockets hole, process a boss at the middle part external diameter or the middle part internal diameter that keep each the pocket hole on the stand, in order to the locking steel ball.Keep middle part, stand pocket hole external diameter to process a boss and be applicable to the QJF ball bearing, keep middle part, stand pocket hole internal diameter to process a boss and be applicable to the QJ ball bearing.The steel ball pocket hole of packing into from the side, the retainer end cap is with keeping stand to be fixed together.Retainer is guided by steel ball.
The utility model is good to the steel ball locking effect, the ball phenomenon can not occur falling, saves the repair time, enhances productivity.
