Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-6, a highly reliable cylindrical roller bearing includes an outer race 1 and an inner race 2, a holder 3 is disposed between the outer race 1 and the inner race 2, both the outer race 1 and the inner race 2 need to be made of GCr15 steel, a plurality of cylindrical rollers 4 are disposed on the holder 3, the cylindrical rollers 4 need to be made of GCr15 steel, an annular groove 5 is disposed around the inner peripheral wall of the outer race 1, a plurality of driven rollers 6 need to be disposed inside the annular groove 5, the driven rollers 6 are in an elliptical structure with thick middle and thin two ends, the driven rollers 6 include a core body 61 and a sleeve body 62 disposed outside the core body 61, the core body 61 needs to be made of aluminum alloy, the sleeve body 62 needs to be made of PC plastic, the driven rollers 6 and the cylindrical rollers 4 need to abut against each other, protrusions 7 need to be disposed at the upper and lower ends of the driven rollers 6, and recesses 8 for the protrusions 7 to be inserted into are disposed on the two side walls of the annular groove 5, the driven roller body 6 is made to be rotatably connected inside the annular groove 5, wherein the protrusion 7 and the concave hole 8 are both cylindrical, and the aperture of the concave hole 8 is larger than the diameter of the protrusion 7.

Because the ring channel 5 has been seted up to circumference on the internal perisporium of outer race 1, be provided with a plurality of driven rollers 6 inside ring channel 5, and from butt each other between driven rollers 6 and cylindrical roller 4, wherein, driven rollers 6 realize rotating inside the ring channel 5 through the inside mode of arch 7 card income shrinkage pool 8 at upper and lower both ends, then when cylindrical roller 4 rolls, can contact and do relative roll with driven rollers 6, then cylindrical roller 4 can drive driven rollers 6 and rotate thereupon, thereby make cylindrical roller 4's roll become more light smooth and easy, thereby effectively guaranteed the result of use of bearing.

Because the driven roller body 6 is an ellipsoid structure with thick middle and thin two ends, the driven roller body 6 only has the middle convex part to be abutted against the peripheral wall of the cylindrical roller 4, so that the contact area of the driven roller body 6 and the cylindrical roller 4 is reduced, and on the basis of not influencing the use effect of the driven roller body 6, the abrasion caused by the rolling between the driven roller body 6 and the cylindrical roller 4 can be effectively reduced, and the rolling of the cylindrical roller 4 is more smooth.

Because the driven roller body 6 includes core 61 and the cover 62 of cover external at core 61, core 61 adopts the aluminum alloy to make, and the aluminum alloy matter is light and intensity is high, and cover 62 adopts PC plastics to make, and PC plastics intensity is high and fatigue resistance is good, and the quality is lighter, and both cooperate the use for driven roller body 6 still has lighter quality when having high strength, then is convenient for to be driven by cylindrical roller 4 and life is longer.

Because arch 7 and shrinkage pool 8 all are cylindrically, and the aperture of shrinkage pool 8 is greater than protruding 7's diameter, then protruding 7 can smoothly block into inside shrinkage pool 8, and because the periphery wall of arch 7 and the internal perisporium of shrinkage pool 8 are the arc surface, then when protruding 7 is in the inside rotation of shrinkage pool 8, can reduce the hindrance for protruding 7's rotation becomes more light smooth and easy.

Because the cylindrical roller 4 is made of GCr15 steel, the GCr15 steel has higher strength and hardness and excellent wear resistance, thereby effectively ensuring the use effect of the cylindrical roller 4.

Because the outer ring 1 and the inner ring 2 are both made of GCr15 steel, the GCr15 steel has high strength and rigidity and strong corrosion resistance, thereby greatly prolonging the service life of the bearing while having high bearing capacity.
