Description
Technical field:
The utility model relates to a kind of sliding bearing, especially a kind of differential self-lubricating plain bearing.
Background technique:
At present, the structure and the material category of sliding bearing are various, as metal sliding bearing, self-lubricating composite sliding bearing etc., but the working speed of above-mentioned bearing all is directly proportional with Sliding velocity, and the operating temperature of bearing and the wearing and tearing of friction surface are also closely related with Sliding velocity.Therefore existing metal sliding bearing must possess Oil Lubrication Condition when work, but under high-revolving operating conditions, it is still bigger to wear and tear, and working life is shorter.The self-lubricating composite sliding bearing uses the PV value low when oil-free lubrication, can't adapt to high rotary speed working, and working life is also shorter, need take oil lubrication to improve usually and use PV value and working life.
Summary of the invention:
The utility model provides a kind of differential self-lubricating plain bearing that adapts to high speed rotating, long service life at the deficiencies in the prior art.
Technical solution of the present utility model is: a kind of differential self-lubricating plain bearing, be provided with inner ring 1 and outer ring 2, it is characterized in that: floating ring 3 is set at inner ring 1 and 2 of outer rings, be provided with accumulator 9 in the floating ring 3, accumulator 9 communicates with inner ring 1 and outer ring 2 by hole 10, the both ends of the surface of floating ring 3 are provided with end cap 8, and end cap 8 is provided with the through hole 11 that communicates with accumulator 9, and end cap 8 joins with inner ring 1 and baffle ring 7 respectively by rolling element 5 and limited ring 6.
The external diameter surface of described inner ring 1 is provided with friction layer 12.
The external diameter surface of described floating ring 3 is provided with friction layer 13.
The inside diameter surface of described outer ring 2 is an inner ball surface, and the external diameter surface of floating ring 3 is an outer spherical surface.
Described accumulator 9 is evenly arranged 16～20 along the circumference of floating ring 3, and the internal diameter of accumulator 9 is 20～30mm; Hole 10 is to communicate with equally spaced 2～4 accumulators 9, and the internal diameter in hole 10 is 0.6～1.0mm.
The outstanding specific floating ring that is to be provided with of the present utility model, when bearing inner race was pressed certain rotary speed working, middle floating ring was differential with respect to inner ring and outer ring generation, and the Sliding velocity with pivot friction face has reduced by 1/3～1/2 thus.And the accumulator storaging liquid lubricant oil that is provided with on the floating ring circumference, supplies to attrition surface with lubricant oil and is lubricated under the siphonage to lubricant oil at centrifugal force and rubbing surface when bearing working, forms from oil feeding system.Because the utility model possesses differential function, from oil feeding system and self-lubricating property, can adapt to high rotary speed working condition, effectively prolong its working life.
