Description
Technical field
This utility model relates to a kind of bearing, specifically a kind of 970 series Solid Self-lubricant Bearings.
Background technology
970 series bearings are that one completely encloses steel ball, and its tolerance support force is strong, but is the most all that grease is smeared in employing or drip-feed lubricating oil carries out bearing lubrication.And using ambient temperature height and mounting location to be difficult in the use occasion of oil addition, due to the grease in bearing or lubricating oil easily by hot setting, the rotating effect of steel ball can be made to reduce, even make bearing lose effect, produce fault.So not only reduce the service life of bearing, also can affect the use equipment of bearing, workpiece or the operating accuracy of facility and service life.
Utility model content
The purpose of this utility model is just to provide a kind of 970 series Solid Self-lubricant Bearings, or is difficult to lubricate the problem causing reduce service life because of lubricating oil solidification with the 970 series bearings solving to use in hot environment.
This utility model is achieved in that a kind of 970 series Solid Self-lubricant Bearings, including outer ring, inner ring and the steel ball of full circle setting between inner ring and outer ring groove, is provided with graphite annulus, spring and dust cap between described inner ring and described outer ring；Described graphite annulus is torus, and its internal diameter is more than the external diameter of described inner ring, and its external diameter is less than the internal diameter of described outer ring；Described spring is squeezed between described dust cap and described graphite annulus, makes described graphite annulus keep elastic pressure to contact with the steel ball of full circle.
Described dust cap is by back-up ring clamper on the interior edge of described outer ring, or clamper is on the outer of described inner ring.
This utility model utilizes spring to be pressed in by graphite annulus on the full circle steel ball of bearing, utilize graphite annulus that steel ball is lubricated, achieve the self-lubricating of 970 series bearings, thus without interpolation and the replacing of lubricating oil, the hot setting problem of lubricating oil is not had yet, thus meet the working condition of 970 series bearings, its rotating effect is made to remain stable, effect will not reduce, avoid the bearing fault and damage thus caused, improve the service life of 970 series bearings, ensure the use equipment of this kind of bearing, workpiece or the operating accuracy of facility.
This utility model can use under the bad working environments of high temperature oil-free lubrication, and has good rotational characteristic, applied widely.This utility model need not oil lubrication or grease lubrication, simple in construction, it is possible to replaces 970 traditional series bearings, is applied to the workplace of various needs.

Detailed description of the invention
Embodiment 1:
As it is shown in figure 1, the 970 series Solid Self-lubricant Bearings of the present embodiment include outer ring 1, inner ring 2 and the steel ball 3 that full circle is arranged between inner ring and the groove of outer ring.The axial length of outer ring 1 and inner ring 2 is more than 970 common series bearings.Graphite annulus 4, spring 5 and dust cap 6 it is provided with between inner ring 2 and outer ring 1.Graphite annulus 4 is torus, and its internal diameter is more than the external diameter of inner ring 2, and its external diameter is less than the internal diameter of outer ring 1.
Having a circle draw-in groove on the interior edge of outer ring 1, back-up ring 7 is connected in draw-in groove, and dust cap 6 is carried out clamper.Spring 5 is squeezed between the end face of dust cap 6 and graphite annulus 4, makes graphite annulus 4 keep elastic pressure to contact with the steel ball 3 of full circle.
Embodiment 2:
As in figure 2 it is shown, the 970 series Solid Self-lubricant Bearings of the present embodiment include outer ring 1 and inner ring 2, have, with the medium position of outer ring 1, the groove that a circle is relative at inner ring 2, be provided with the steel ball 3 of full circle in the trench.The axial length of outer ring 1 and inner ring 2 is more than the outer ring 1 in embodiment 1 and the axial length of inner ring 2.Graphite annulus 4, spring 5 and dust cap 6 it is provided with between inner ring 2 and outer ring 1.Graphite annulus 4 has two, sets up the upper/lower terminal at full circle steel ball 3 separately.Graphite annulus 4 is torus, and toric internal diameter is more than the external diameter of inner ring 2, and toric external diameter is less than the internal diameter of outer ring 1.The size of two graphite annulus 4, shape correspondence are identical.
Having a circle draw-in groove on the outer, two ends of inner ring 2, back-up ring 7 is connected in draw-in groove, and dust cap 6 is carried out clamper.Spring 5 is squeezed between the end face of dust cap 6 and graphite annulus 4, makes graphite annulus 4 keep elastic pressure to contact with the steel ball 3 of full circle.
