Abstract
The invention discloses a deep groove ball bearing provided with a lubrication oil hole. The deep groove ball bearing comprises an inner ring 02 and an outer ring 01 which are sleeved concentrically inside and outside. Steel balls 04 are fixed between the inner ring 02 and the outer ring 01 through a cage. The cage comprises a cage cover 16 and a cage base 06 which are riveted by rivets 09. The middle part of the outer cylindrical surface of the outer ring is provided with a through oil hole vertically leading to the steel balls. The oil hole faces right towards the center of the steel balls. An oil groove and the oil hole are disposed in the outer ring, and the oil and grease can enter into the inside of the bearing during the motion process of the bearing and plays a role of lubricating the bearing, and therefore the service lifetime of the bearing is prolonged, a machine is not needed to be stopped due to addition of lubricating oil, and the working efficiency is increased. Impurities are liable to enter into the bearing during working, and once the impurities enter, rotation and the service lifetime of the bearing are largely influenced. By addition of the oil groove and the oil hole, the impurities are liable to flow out from the oil hole, thus prolonging the service lifetime of the bearing and guaranteeing the rotation.
Description
Technical field
The present invention relates to technical field of bearings.
Background technique
The structure of deep groove ball bearing as shown in Figure 1, comprises inside and outside inner ring 02 and the outer ring 01 of socket with one heart, between described inner ring 02 and outer ring 01, is fixed with steel ball 04 by retainer, and described retainer comprises by the retainer lid 16 of rivet 09 anchoring and keeps stand 06.
Deep groove ball bearing is generally positioned at the occasion that rotating speed is higher, and problem is, under the very high environment of rotating speed, must provide sufficient lubricant oil to deep-groove ball.If do not provide sufficient lubricant oil, easily cause that bearing temperature raises, and accelerate oil deterioration, reduce the working life of bearing.And generally, because deep groove ball bearing relatively seals, in movement process, if want to provide sufficient lubricant oil to bearing, be difficult to accomplish.If the machine interpolation lubricant oil that stops, not only handling trouble, wastes time, and easily damages bearing.
Summary of the invention
The present invention aims to provide a kind of deep groove ball bearing that facilitates charging-up lubricant oil.
In order to achieve the above object, the invention provides a kind of deep groove ball bearing that profit oilhole is set, comprise inside and outside inner ring and the outer ring of socket with one heart, between described inner ring and outer ring, be fixed with steel ball by retainer, described retainer comprises the retainer lid maintenance stand by rivet anchoring; Wherein, the outer cylinder of described outer ring middle part offers an oilhole that vertically leads to described steel ball; Described oilhole faces the center of described steel ball.
The present invention increases oil groove oilhole in outer ring, bearing can well enter bearing inside by grease in movement process, plays lubricating bearings effect.So not only improve the work working life of bearing, machine can also stop because of adding lubricant oil, strengthens working efficiency.And bearing time is easy to enter impurity in work, if once enter, rotation and working life to bearing all have a significant impact.Increase oil groove oilhole, impurity easily flows out from oilhole.Strengthen bearing working life, guarantee rotation.

Embodiment
The present invention arranges the deep groove ball bearing of profit oilhole as shown in Figure 2, comprise inside and outside inner ring 02 and the outer ring 01 of socket with one heart, between described inner ring 02 and outer ring 01, be fixed with steel ball 04 by retainer, described retainer comprises by the retainer lid 16 of rivet 09 anchoring and keeps stand 06; Wherein, the outer cylinder of described outer ring 01 middle part offers an oilhole A who vertically leads to described steel ball 04; Described oilhole A faces described steel ball 04 center.
The above; it is only preferably embodiment of the present invention; but protection scope of the present invention is not limited to this; any be familiar with those skilled in the art the present invention disclose technical scope in; be equal to replacement or changed according to technological scheme of the present invention and inventive concept thereof, within all should being encompassed in protection scope of the present invention.
