Abstract

The invention discloses an elastic bearing based on double retainers. The elastic bearing comprises an outer ring, an inner ring, the first retainer and the second retainer. A first groove raceway isarranged on the inner wall of the outer ring. A second groove raceway is arranged on the outer wall of the inner ring. The inner ring and the outer ring are arranged concentrically. The first retainerand the second retainer both are circular-ring elastic bodies in a wave shape and are arranged in a staggered manner so that the wave crest and the wave trough on the first retainer can correspond tothe wave crest and the wave crest on the second retainer one by one. Clamping mechanisms which are provided with cylindrical rollers and matched with the first groove raceway are correspondingly arranged outwards on the wave crests of the first retainer and the second retainer, and clamping mechanisms which are provided with cylindrical rollers and matched with the second groove raceway are correspondingly arranged inwards on the wave troughs of the first retainer and the second retainer. The elastic bearing based on the double retainers is convenient to use, the radial bearing capacity of the bearing is improved, and the impact load received by a bearing seat is lowered greatly.

Description

technical field [0001] The invention relates to an elastic bearing, in particular to an elastic bearing based on double cages. Background technique [0002] Needle roller bearings or sliding bearings are generally used when selecting gears for shafts bearing large unbalanced radial forces, which lack elasticity and self-adjusting shock absorption and buffering functions, and places with high rigidity and damping values ​​are difficult to last. Using it, the problem continues. The invention greatly improves the stiffness value and damping value of the elastic bearing, has good elasticity and has the functions of self-adjustment and self-correction. Existing needle roller bearings or sliding bearings can withstand large radial forces. For example, take the gear pump as an example. The gear pump is an unbalanced hydraulic oil pump with symmetrical oil suction and oil pressure areas. From the oil suction chamber to the oil pressure chamber, the pressure decreases tooth by toot...
