Abstract
The utility model discloses a deep groove ball bearing for a push rod motor, which 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 way; the depth of the grooves of the inner ring and the outer ring is L, the radius of the sphere is R, wherein,
(ii) a 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.
Description
Technical Field
The utility model relates to a bearing field, more specifically say, it relates to a deep groove ball bearing that push rod motor used.
Background
The Bearing (Bearing) is an important part in the modern mechanical equipment. Its main function is to support the mechanical rotator, reduce the friction coefficient in its motion process and ensure its rotation precision. The push rod motor is converted into linear reciprocating motion through the rotating motion of the motor, the push rod is subjected to the flat power in all directions in the linear reciprocating motion, and the push rod motor mainly transmits the axial load of the rotating shaft through the bearing, so that when the common deep groove ball bearing is used on the push rod motor, the service life of the bearing cannot be expected, and failures such as fatigue stripping and the like occur in advance.
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,
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,
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.
