SUMMERY OF THE UTILITY MODEL
The utility model discloses a main aim at provides a deep groove ball bearing that push rod motor was used, simple structure not only, long service life can not appear fatigue in advance and peel off the phenomenon moreover.
In order to achieve the above purpose, the utility model adopts the technical scheme that: a deep groove ball bearing for a push rod motor comprises an inner ring, an outer ring, a ball body and a retainer, wherein the ball body is connected between the inner ring and the outer ring in a rolling mode; the depth of the grooves of the inner ring and the outer ring is L, the radius of the sphere is R, wherein,
Figure BDA0002467083240000011
by increasing the depth of the groove, when the bearing is subjected to axial load, the contact area of the ball body and the groove is increased, so that stress concentration in the bearing is avoided, and the contact pressure in the bearing is reduced, thereby improving the running reliability of the bearing, prolonging the service life of the bearing, and avoiding fatigue spalling in advance.
In a further technical scheme, the method comprises the following steps of,
Figure BDA0002467083240000012
in a further technical scheme, the outer ring is provided with first ring grooves on two sides of the sphere, the inner ring is provided with second ring grooves on two sides of the sphere, and an annular dustproof cover is clamped between the first ring grooves and the second ring grooves; set up in the shield can prevent that dust or silt from getting into the bearing, influence the use of bearing, reduce the life of bearing.
In a further technical scheme, the dustproof cover is connected with the side face of the retainer through a bolt; a through hole is formed in the dustproof cover along the axial direction of the bearing, and the bolt penetrates through the through hole and is connected to the side face of the retainer in a threaded mode; this setting can prevent that the shield from droing in the use.
In a further technical scheme, a pocket for placing a ball body is formed in the retainer, and a plurality of oil storage tanks are formed in the inner side wall of the pocket; the oil storage tank is arranged, so that the lubrication of the ball body can be kept, and the abrasion of the ball body is reduced.
The utility model has the advantages that: according to the invention, the depth of the grooves of the inner ring and the outer ring is increased, so that the contact area between the ball body and the grooves is increased, stress concentration in the bearing is avoided, and the contact pressure in the bearing is reduced, thereby improving the running reliability of the bearing, prolonging the service life of the bearing, and avoiding fatigue spalling in advance; the dustproof cover is connected with the side surface of the retainer through a bolt; the dust cover can be prevented from falling off in the using process.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In the description of the present invention, it is to be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are merely for convenience of description and for simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.
As shown in fig. 1, a deep groove ball bearing for a push rod motor comprises an inner ring 1, an outer ring 2, a ball 3 connected between the inner ring 1 and the outer ring 2 in a rolling manner, and a retainer 4 arranged outside the ball 3; the depth of the grooves of the inner ring 1 and the outer ring 2 is L, the radius of the sphere 3 is R, wherein,
Figure BDA0002467083240000021
here, the
Figure BDA0002467083240000022
Outer lane 2 is equipped with first annular 21 in spheroidal 3 both sides, inner circle 1 is equipped with second annular 15 in spheroidal 3 both sides, the joint has annular shield 5 between first annular 21 and the second annular 15, sets up shield 5 and can prevent that dust or silt from getting into the bearing in, influences the use of bearing, reduces the life of bearing. The dustproof cover 5 is connected with the side surface of the retainer 4 through two bolts 6; a through hole 51 is formed in the dustproof cover 5 along the axial direction of the bearing, and the bolt 6 penetrates through the through hole 51 and is connected to the side face of the retainer 4 in a threaded mode; this arrangement can prevent the dust cap 5 from falling off during use.
