Abstract
The utility model relates to a ball-shaped cage packet retainer for a trench ball bearing, which comprises two half annular retainers (3) and a plurality of cage packets (6) arranged on the retainers, wherein the half annular retainers (3) are fixedly connected by rivets (2) after butt joint, and the cage packets (6) immediately form a cage packet shape. Because the shape of the cage packets is designed into a ball shape, and a more precise guide mode which is rolling body guide is adopted, the shape of the cage pockets of the retainers and the shape of the rolling body are kept uniform, and the clearances between a ferrule flange and the outer diameters or the inner diameters of the retainers are enlarged. Lubricating oil is easy to enter in a method that grooves are arranged on the outer diameters and the inner diameters of the retainers, therefore, the lubricating property of the bearing is efficaciously improved to make the bearing have favorable running quality and extend the service life of the bearing. The utility model has the characteristics of high intensity, high abrasion resistance, high reliability, low oscillation, low noise and high rigidity and is suitable for high speed running.
Description
Affiliated technical field
The utility model belongs to the retainer technical field, and what relate generally to is a kind of deep groove ball bearing with spherical pocket hole retainer.
Background technique
The retainer that deep groove ball bearing is commonly used has steel plate punching press ribbon retainer, engineering plastics cage and car manufacture-yellow copper or bronze two halves retainer.Middle-size and small-size deep groove ball bearing generally adopts steel plate punching press ribbon retainer, and its intensity is better, and weight is also light.That engineering plastics cage has is in light weight, self-lubricating property good, the advantage of shock-resistant, antivibration and noise reduction, but also have poor dimensional stability, damp and hot expansion is big, intensity is low, the weakness of resistance to heat difference.These two kinds of retainers are used in lower, the occasion stably of loading of rotating speed usually.If bearing rotating speed height, acceleration are big or bear heavy load, impact load, then consider from lubricated and intensity aspect, need to adopt copper cage.Existing car manufacture-yellow copper or bronze two halves retainer adopt outer ring 1 or inner ring 4 lip-guideds more, pocket hole 6 is shaped as cylindrical, (shown in Fig. 4-5) is because this retainer guide clearance is little, lubricant medium is difficult to enter, it is big to add holder 3 radial-play amounts, easy and retainer external diameter or internal diameter generation friction, wearing and tearing and heating of lasso rib had a strong impact on the normal operation of deep groove ball bearing when running up.
Summary of the invention
The purpose of this utility model promptly produces thus, proposes a kind of deep groove ball bearing with spherical pocket hole retainer.This retainer adopts the rolling element guidance mode, has improved the greasy property of bearing, the operational reliability and the working life of having improved bearing.
For achieving the above object, the technological scheme that the utility model is taked is: it has two identical half sheet annular retainers, pocket hole shape on each half sheet annular retainer is hemisphere, this two and half sheets annular retainer butt joint back is fixedly connected by rivet, its hemisphere pocket hole shape globulate pocket hole.
The utility model is reasonable in design, because its shaped design with the pocket hole is spherical pocket hole, take more accurate guidance mode---the rolling element guiding, be that retainer pocket hole shape and rolling element shape are consistent, so just strengthened the gap between lasso rib and retainer external diameter or the internal diameter, and by on retainer external diameter, internal diameter, slotting, make lubricant oil be easy to enter, therefore, improve the greasy property of bearing effectively, make bearing have good riding quality, thereby prolonged the working life of bearing.This retainer also has high strength, high wear resistance, high reliability, low vibration, low noise, high rigidity, the characteristics that are suitable for running up.

Embodiment
In conjunction with the accompanying drawings, it is as follows to provide embodiment of the present utility model:
As Figure 1-3, present embodiment mainly is made of two identical half sheet annular retainers 3, and a plurality of pockets hole 6 on each half sheet annular retainer 3 is hemisphere SR shape.These two and half sheets annular retainer, 3 butt joint backs are fixedly connected by rivet 2, and hemisphere pocket hole promptly forms spherical pocket hole S φ.Retainer is made by brass or bronze, has groove 7 on retainer 3 external diameters, internal diameter.During the present embodiment assembling, retainer 3 is between outer ring 1 and inner ring 4, and steel ball 5 is installed in the cage ball pocket 6.
Claims (2)
1, a kind of deep groove ball bearing is with spherical pocket hole retainer, comprise two and half sheets annular retainer (3) and a plurality of pockets hole (6) that is provided with thereof, this two and half sheets annular retainer (3) is connected by rivet (2), it is characterized in that: the pocket hole (6) on described each half sheet annular half retainer (3) is hemisphere, and its pocket hole (6), two and half sheets annular retainers (3) butt joint back is spherical pocket hole.
2, deep groove ball bearing according to claim 1 is characterized in that: have groove (7) on described retainer (3) external diameter, internal diameter with spherical pocket hole retainer.
