Abstract
The invention relates to a bearing. The bearing comprises a bearing outer ring and a bearing inner ring. The bearing is characterized in that a rolling ball is arranged between the bearing outer ring and the bearing inner ring, wherein at least one lubricating path is formed in the bearing inner ring along the radial direction; a lubricating hole is formed in the bearing inner ring along the axial direction; the lubricating hole is communicated with the lubricating path; the rolling ball is in a hollow structure; and the inner surface of the bearing outer ring comprises a plurality of circular-arc-shaped concave parts which are connected in sequence. The bearing has light weight, small heat capacity, good lubricating effects, long service life and reliability, and also can be prevented from being blocked while being prevented from slipping.
Description
Technical field
The present invention relates to a kind of bearing.
Background technique
There is a kind of bearing in the market, this bearing is provided with axis hole at bearing inner race, this bearing inner race is provided with oilhole along axle, bearing inner race is radially provided with oil duct, and oilhole communicates with oil duct, and communicates with the outer side wall of shaft hole inner wall and bearing inner race, axle is inserted axis hole, add oil in oilhole, oil flows into shaft hole inner wall and ball position by passage, and the good bearing operation noise of moisturizing effect is low.But the bearing ball of this structure is solid construction, quality is large, and thermal capacity is large, easily occurs " killing " phenomenon during use.
Summary of the invention
For problems of the prior art, the object of the present invention is to provide a kind of technological scheme of bearing.
Described a kind of bearing, comprise outer race and bearing inner ring, it is characterized in that being provided with ball between described outer race and bearing inner ring, this bearing inner ring is radially provided with at least one lubrication road, bearing inner ring is provided with a lubrication hole vertically, this lubrication hole is connected with lubrication road, and described ball is hollow-core construction, and the internal surface of outer race comprises multiple circular arc-shaped recess connected successively.
Described a kind of bearing, is characterized in that described circular arc-shaped recess is 3-6, and is distributed on the internal surface of described outer race.
Described a kind of bearing, is characterized in that described lubrication hole is 4-6.
Described a kind of bearing, is characterized in that described lubrication hole is equal with the radius in lubrication road.
The present invention is lightweight, thermal capacitance is little, high lubricating effect, and anti-slip also prevents stuck simultaneously, long service life and reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with Figure of description, the present invention will be further described:
A kind of bearing, comprise outer race 1 and bearing inner ring 2, be provided with ball 7 between described outer race 1 and bearing inner ring 2, this bearing inner ring 2 is radially provided with at least one lubrication road 6, and bearing inner ring 2 is provided with a lubrication hole 5 vertically, this lubrication hole is circular, lubrication hole 5 is connected with lubrication road 6, and described ball 7 is hollow-core construction, and this structure has saved resource, alleviate weight and the thermal capacity of rolling bearing, avoid " killing " phenomenon occurs.The internal surface of described outer race 1 comprises multiple circular arc-shaped recess 8 connected successively, this circular arc-shaped recess 8 only has several microns apart from original track 9, connect described circular arc-shaped recess 8 successively, do not affect the rolling of ball 7, because the existence of circular arc-shaped recess 8, bearing ball 7 when high speed rotating can produce trace circular to outer race 1 in raceway and impact between outer race 1 and bearing inner ring 2, this trace circular impact be applied to bearing support and outer race 1 by outer race 1 fitting surface on quite add preload to bearing, adopt the method effectively can avoid skidding, improve the working life of bearing.
As preferably, circular arc-shaped recess 8 is set to 3, and is evenly distributed on the interior roller surface of described outer race 1, also can be set to 4-6, the better effects if preventing to skid can be made.
The number of lubrication hole 5 is 6 from multiple holes lubricating oil filling, can be made lubrication more even, the better effects if of lubrication, certainly also can be set to 4 or 5.
In order to make lubricating oil filling more convenient, described lubrication hole 5 radius is set to equal with lubricating 6 radiuses.
The present invention is lightweight, thermal capacitance is little, high lubricating effect, and anti-slip also prevents stuck simultaneously, long service life and reliable.
