Background
When the fan runs, the axis rotates in the bearing. The axle center contacts with the bearing, and when the fan works for a long time, a large amount of heat is generated between the axle center and the bearing, so that the bearing and the axle center generate heat, and the heat can be transferred to other parts of the fan. At present, in order to reduce the heat generated by the rotational movement, hydraulic oil or cooling oil is filled between the bearing and the shaft core. However, in the cooling process of the conventional fan, the hydraulic oil or the cooling oil stays between the bearing and the axis, and the heat is accumulated in the hydraulic oil but is not dissipated, so that the heat dissipation effect is not good.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide an oil return bearing and a fan thereof, which enable lubricating oil serving as a lubricating function to circularly flow inside and outside along an oil return groove and an axial groove of a bearing body and a central hole of the bearing body while rotating at an axis, and have the advantages of oil retention and product service life improvement.
In order to solve the technical problems, the technical scheme provided by the utility model is as follows: the utility model provides an oil return bearing, includes the bearing body, and the bearing body is equipped with the centre bore, and the terminal surface of bearing body is equipped with the oil gallery, is equipped with the axial groove that links up with the oil gallery at the lateral wall of bearing body.
By adopting the technical scheme, the axis of the fan rotates in the central hole, lubricating oil is thrown out during rotation, and flows in the oil return grooves and the axial grooves on the two end surfaces of the bearing to dissipate heat, so that heat accumulation is avoided, and the heat dissipation effect is better.
Furthermore, an expanded oil return cavity is arranged in the central hole of the bearing body. The oil return cavity can retain more lubricating oil, and heat generated by friction between the axis and the bearing can be effectively absorbed and transferred through the lubricating oil.
Further, the outer wall of the bearing body is provided with an inner concave ring extending to the bottom end. The inner concave ring is used for enlarging the gap between the outer wall of the bearing and the inner cavity of the stator when the bearing is arranged inside the stator, and the fluidity of lubricating oil is improved.
Furthermore, an inclined plane is arranged at the position close to the inner concave ring along the axial groove. The inclined surface is connected with the inner recess in a replaceable manner, so that the flow of lubricating oil is facilitated.
Furthermore, the oil return groove is in a trapezoidal shape and is reduced in diameter towards the axis direction. When lubricating oil flows out of the outer wall of the bearing from the center of the bearing and flows out through the oil return grooves in the trapezoidal radial shape, the lubricating oil is uniformly dispersed, and the heat conduction effect is improved.
In order to solve the above technical problem, another technical solution provided by the present invention is: the utility model provides a fan, includes stator and rotor, is equipped with positioning sleeve in the stator, be equipped with above-mentioned technical scheme any in the positioning sleeve oil return bearing, the rotor rotationally wears to locate in the bearing through the axle center, the other end in axle center is connected with the flabellum.
By adopting the technical scheme, the axis of the rotor of the fan rotates relative to the bearing, and the generated heat has the advantages of good fluidity and good heat dissipation and oil retention effects under the guidance of the oil return groove and the axial groove of the bearing through the lubricating oil.
Furthermore, an inner convex ring is arranged in the stator and is abutted against the end face of the bearing body. The inner convex ring is propped against the end surface of the bearing, and the lubricating oil circularly flows from an oil return groove on the end surface of the bearing.
The beneficial effects obtained by the utility model are as follows: through the structural design to the bearing for the lubricating oil of packing between bearing and axle center has better mobility, and the heat transfer and the dispersion that can be fine produce axle center and bearing are gone out, improve the radiating effect, and the length of time is used with the bearing to the extension axle center.

Description of reference numerals: the bearing comprises a bearing body 1, a central hole 10, an oil return groove 11, an axial groove 12, an oil return cavity 13, an inner concave ring 14, an inclined plane 15, a stator 2, a positioning sleeve 21, an inner convex ring 22, a rotor 3, an axis 31 and fan blades 32.
Detailed Description
The utility model is further described with reference to the following figures and detailed description.
Referring to fig. 1 to 5, an oil return bearing includes a bearing body 1, the bearing body 1 is provided with a central hole 10, an end face of the bearing body 1 is provided with an oil return groove 11, and a side wall of the bearing body 1 is provided with an axial groove 12 connected with the oil return groove 11. Lubricating oil flows out to bearing body 1 outer wall from oil gallery 11 in bearing body 1, flows to axial groove 12 when flowing to the outer wall, and axial groove 12 will flow from the lubricating oil drainage that flows out in oil gallery 11 to the other end of bearing body 1, forms lubricating oil and circulates at the both ends of bearing body 1 to promote the cooling effect. Preferably, oil return grooves 11 are formed in both end surfaces of the bearing body 1, so that the circulation effect of the lubricating oil is improved better.
An oil return cavity 13 with the diameter expanded is arranged in the central hole 10 of the bearing body 1. The cooling oil or the hydraulic oil stays in the oil return cavity 13, and the diameter of the oil return cavity 13 is larger than that of the central hole 10, so that the stay amount and the flow amount of the lubricating oil can be increased, and the cooling effect is improved.
The outer wall of the bearing body 1 is provided with an inner concave ring 14 extending to the bottom end. A bevel 15 is provided along the axial groove 12 adjacent to the inwardly concave ring 14. At the bottom of bearing body 1, the setting of indent ring 14 and inclined plane 15 can increase the clearance of bearing body 1 and stator inner wall, promotes the mobility of lubricating oil. Wherein, the oil return groove 11 is in a trapezoidal shape and is reduced in diameter towards the axial direction. The lubricating oil is thrown from the axis of the shaft rotated by the shaft center of the bearing body 1, flows out from the trapezoidal upper bottom with smaller size of the oil return groove 11, flows to the axial groove 12 from the lower bottom with larger size, forms good circulating flow effect, and continuously takes out the heat generated between the axis and the bearing.
Referring to fig. 1 to 7, a fan includes a stator 2 and a rotor 3, a positioning sleeve 21 is disposed in the stator 2, an oil return bearing according to the above embodiment is disposed in the positioning sleeve 21, the rotor 3 rotatably penetrates the bearing through an axis 31, and the other end of the axis 31 is connected to a fan blade 32.
The stator 2 is internally provided with an inner collar 22 which abuts against the end face of the bearing body 1. Interior collar 22 supports the up end at bearing body 1 for the installation fixed bearing, the cooling oil flows out in the clearance of interior collar 22 and oil gallery 11, and interior collar 22's setting has avoided the inner wall of stator 2 and the top laminating of bearing body 1 tension to influence the flow of lubricating oil.
