Problems solved by technology
However, when the bearing rotates, a large amount of heat will be generated, which will cause wear and tear on the device. Although the existing technology can reduce the temperature by adding ventilation holes, it is impossible to adjust the flow rate of the gas flowing through the inner cavity of the bearing according to the heating temperature of the bearing. Adaptive cooling, this problem needs to be solved urgently

Embodiment Construction
[0016] Such as figure 1 as shown, figure 1 It is a schematic structural diagram of a gas-sealed self-adaptive temperature-adjusting bearing proposed by the present invention.
[0017] refer to figure 1 , a gas-sealed self-adaptive temperature-adjusting bearing proposed by the present invention can be used in occasions where conventional sealing elements cannot be assembled due to structural and environmental restrictions, and sealing, cooling or heating are required; the bearing includes: an outer ring 1, an inner ring 2, Rolling mechanism 3, retaining ring 4, movable ring 5, spring leaf 6;
[0018] The outer ring 1 is located outside the inner ring 2, and the rolling mechanism 3 is arranged between the outer ring 1 and the inner ring 2. The rolling mechanism 3 includes a cage and rolling elements, and the rolling elements are set in the cage. During the installation process, the outer ring 1 Fixed, the inner ring 2 rotates;
[0019] The two retaining rings 4 are interfere...

The invention discloses an air seal self-adaption temperature regulation bearing. Outer rings are positioned at the outer sides of inner rings; rolling mechanisms are arranged between the outer rings and the inner rings, and comprise holders and rolling bodies in the holders; two retainer rings are in interference fit with the inner circumferences at two ends of the outer rings; two movable rings are in clearance fit with the inner circumferences of the two retainer rings; spring sheets are fixed on the outer ends of the retainer rings and are used for keeping the movable rings between the inner rings and the retainer rings by virtue of the elastic force of the spring sheets; annular clearances are formed between the inner circumferences of the two movable rings and the outer peripheries of the inner rings; the outer rings, the inner rings, the retainer rings and the movable rings form a bearing inner cavity; the outer rings are provided with air inlets communicated with the bearing inner cavity; the annular clearances are air outlets for communicating the bearing inner cavity to the outside of the cavity; the bearing regulates the rate of flow of air flowing through the inner cavity according to the heating temperature of the inner cavity in a self-adaption mode. According to the invention, introduced air not only can be used for sealing the bearing, but also can regulate the rate of flow of air flowing through the bearing inner cavity according to the heating temperature of the bearing inner cavity in a self-adaption mode, and thus the self-adaption cooling of the bearing is realized.
Description
technical field [0001] The invention relates to the technical field of bearings, in particular to a gas-sealed self-adaptive temperature-regulating bearing, which can self-adaptively adjust the flow rate of gas flowing through the inner cavity of the bearing according to the heating temperature of the bearing. Background technique [0002] Bearings are components that fix and reduce the friction coefficient of loads during mechanical transmission. When other parts move relative to each other on the shaft, it is used to reduce the friction coefficient during power transmission and keep the center of the shaft fixed. The main function of the bearing is to support the mechanical rotating body to reduce the friction coefficient of the mechanical load during the transmission process of the equipment. However, when the bearing rotates, a large amount of heat will be generated, which will cause wear and tear on the device. Although the existing technology can reduce the temperatur...
