Abstract
A high-temperature-resistant retainer-free self-aligning roller composite bearing relates to a bearing used between a rotating shaft and a bearing frame. The utility model discloses a bearing is including outer lane, well circle and inner circle, and the inner face of well circle has several annular grooves, and the inslot is arranged in proper order to the roller, and the roller is not hard up the cooperation between inner circle external diameter and annular groove, and the external diameter of well circle is the sphere, and with the interior sphere clearance fit of outer lane, outer lane and well circle design have tank filler hole and oil storage tank respectively. The number of the annular grooves on the inner surface of the middle ring is 1-5, the number of the rollers in the annular grooves is determined according to the diameter of the rollers, and small gaps are reserved among the rollers. The utility model has the advantages that: the roller bearing with the retainer and the self-aligning roller bearing can effectively replace the traditional roller bearing with the retainer, and the single function of the roller bearing and the self-aligning roller bearing is changed into a composite function. The device can be widely used in severe environments with high temperature, large impact force, long distance and much dust.
Description
One, technical field
The utility model relates to a kind of bearing that is used between rotatingshaft and bearing bracket stand.
Two, background technique
We learn in practice: the bearing under the hot operation state often since following factors lost efficacy: the one, retainer was stuck when thermal expansion amount exceeded bearing and dispatches from the factory the gap; The 2nd, lubricating grease at high temperature is carbonized, and bearing is worked under dry condition damage because of oil starvation; The 3rd, transmission shaft distortion causes bearing to be hit irregular external force load is excessive and causes retainer to damage and fall apart.
Three, summary of the invention
The purpose of this utility model is a kind of roller bearing and selfaligning roller bearing that substitutes traditional band retainer of design.
The bearing of the utility model design is to include outer ring, centre circle and inner ring, the inner face of centre circle has several circular groove, roller places in the groove successively, roller is running fit between inner ring external diameter and circular groove, the external diameter of centre circle is a sphere, with the inner ball surface Spielpassung of outer ring, outer ring and centre circle have designed tank filler sleeve and oil storage tank respectively.The circular groove number of centre circle inner face is between 1～5, and the roller number in the circular groove is decided on its diameter, and less gap is arranged between roller.
Because centre circle has been cancelled retainer, the running fit of roller between inner ring external diameter and circular groove overcome the stuck problem of retainer that thermal expansion causes.Roller is made circular movement under the frictional force of inner ring drives, its bearing capacity is big, because the roller use is that roundlet roller shape has reduced friction factor, has also improved the linear velocity of bearing.The swing (general 3 °～8 °) that the outer spherical surface Spielpassung of outer ring inner ball surface and centre circle can make centre circle do by a small margin around axis has absorbed the caused irregular impact external force of transmission shaft bending.Can effectively substitute the roller bearing and the selfaligning roller bearing of traditional band retainer, make the simple function of the two become complex function.Can be widely used in the temperature height, impact force is big, distance, dusty rugged environment position.

Fig. 1 is the overall structure schematic representation;
Fig. 2 is the A-A cross-sectional view.
Five, embodiment
With the centre circle inner face three road circular grooves being arranged is example, and the number of circular groove is decided with the weight of being carried.The structure of this bearing is that outer ring 1 is arranged, be equipped with centre circle 2 in the outer ring, be equipped with inner ring 3 in the centre circle, cooperate for loosening sphere between outer ring 1 inner face and centre circle 2 outsides, the inner face of centre circle 2 has three road circular grooves 5, and roller 4 places in the circular groove 5, and number is decided on the circular groove diameter, to fill up substantially, between less space is arranged.Roller 4 is running fit between inner ring external diameter and circular groove.For keeping the flexible rotation of this bearing, outer ring 1 and centre circle 2 are respectively arranged with tank filler sleeve 6 and oil storage tank 7.The parts of this device are by the bearing steel material.For the integral body assembling, when making outer ring 1, to highly be slightly larger than centre circle 2 diameters between 8, two gap of gap of Ge Qie up and down in a side.With molybdenum disulfide roller 4 is adhered in the circular trough 5 again, centre circle 2 is vertically entered in the outer ring from 8 of gap, then, revolve to turn 90 degrees centre circle 2 outer spherical surfaces are overlapped with outer ring 1 inner ball surface, again inner ring 3 is inserted in the centre circle at last and get final product.
Claims (2)
1, a kind of high temperature resistant no retainer aligning roller composite bearing, it is characterized in that: it includes outer ring (1), centre circle (2) and inner ring (3), the inner face of centre circle has several circular groove (5), roller (4) places in the groove successively, roller (4) is running fit between inner ring (3) external diameter and circular groove (5), the external diameter of centre circle (2) is a sphere, and with the inner ball surface Spielpassung of outer ring (1), outer ring (1) and centre circle (2) design respectively tank filler sleeve (6) and oil storage tank (7).
2, according to the described a kind of high temperature resistant no retainer aligning roller composite bearing of claim 1, it is characterized in that: circular groove (4) number of centre circle (2) inner face is between 1～5.
