Description

Motor shaft core integrated bearing structure Technical Field The invention relates to the technical field of motor support, in particular to an adjustable motor shaft core integrated bearing structure. Background The motor bearing is a core supporting component of the motor, and is a bearing specially applied to the motor or the motor, and the main functions of the motor bearing are to support the rotation of a rotor shaft of the motor, reduce friction and bear radial or axial load. Rolling bearings such as deep groove ball bearings and cylindrical roller bearings are commonly adopted for small and medium-sized motors, and running stability is guaranteed through grease lubrication or oil lubrication. In motor assembly, the fixing mode of the bearing and the shaft directly influences the precision of the whole machine, vibration noise and service life. However, the existing bearing structure still has obvious short plates in terms of installation suitability and maintainability, and is difficult to meet the requirements of efficient and flexible production. The existing motor bearing and shaft are fixed generally by means of interference fit press-fitting, internal stress damage is easy to occur in the installation process, disassembly and maintenance are difficult, and the traditional bearing is installed by adopting a press-in or heating fit interference-fixing mode directly. The mode is easy to cause microscopic deformation, scratch and even fracture on the surface of the bearing inner ring or the shaft neck due to uneven stress in the press mounting process, and meanwhile, interference fit can reduce internal clearance of the bearing and increase friction temperature rise and noise during operation. When the bearing is required to be replaced or the rotor is required to be maintained, the disassembling process is usually required to be forcedly withdrawn by means of tools such as a puller, so that irreversible damage is easily caused to the precision of the journal, the maintenance cost and time are increased, and the maintainability of equipment is reduced. The prior motor bearing structure has fixed size, lacks adjustability, is difficult to adapt to rotor shaft diameters of different specifications, the traditional bearing is a standardized part, and the aperture of an inner ring of the traditional bearing is a fixed value, so that the traditional motor bearing can only be matched with a rotor shaft with a specific diameter. When different shaft diameters are involved in motor design or maintenance, bearings of different types must be replaced, which not only increases spare part inventory and management costs, but also limits the serial development and flexible production of motor products. Under the scene of frequent rotor replacement such as research and development, test, the fixed bearing specification reduces work efficiency and adaptability more.
