High-speed shaft connecting bearing for dust collector

Abstract

The invention relates to a high-speed shaft connecting bearing for a dust collector. The high-speed shaft connecting bearing comprises a core shaft, an outer ring, a plurality of rolling elements, retainers and sealing elements. The core shaft is sleeved with the outer ring. The retainers are arranged between the core shaft and the outer ring. The rolling elements distributed uniformly are arranged in the retainers. The sealing elements are arranged on the two sides of the retainers. According to the high-speed shaft connecting bearing for the dust collector, there is no need to assemble multiple parts, and the form that a shaft, a bearing, a bearing chamber, a spring assembly and other parts are combined is canceled. The high-speed shaft connecting bearing adopts the integrated design andcan be used conveniently. The core shaft has the effects equivalent to the effects of an inner ring and a shaft in a bearing for a common dust collector. The bearing outer ring is used for replacingan original bearing chamber. The bearing is integrally designed. The spring assembly in the bearing is omitted. Assembly errors are reduced. The instability caused by complex assembling is avoided. The overall accuracy is improved. Energy consumption is reduced. The cost is reduced.

Description

technical field [0001] The invention relates to a high-speed shaft-connected bearing for a vacuum cleaner, which belongs to the field of bearings for a vacuum cleaner. Background technique [0002] In the vacuum cleaner bearings in the prior art, such as figure 2 As shown, a shaft 7 is included, two bearings 8 are sleeved on the shaft 7, a spring assembly 9 is arranged between the bearings 8, and the two bearings 8 and the spring assembly 9 are arranged in the bearing chamber 6. [0003] The installation space of the above-mentioned vacuum cleaner bearing is small, and the steps for installation and use are complicated and the operation is not easy. And because the bearing chamber 6 and the spring assembly 9 are needed in addition to the bearing, the number of required parts is large and needs to be provided by different suppliers, which increases the user's cost. [0004] From the perspective of energy saving and environmental protection, in the case of high-speed and low...
