Specific embodiment
With reference to the accompanying drawings and examples, specific embodiments of the present invention will be described in further detail.Implement below Example cannot be used to limit the scope of the invention for illustrating the present invention.
The adjustable concentricity of the embodiment of the present invention high speed laundry machine bearing structure include as shown in Figures 1 to 4:One Outer ring 1, an inner ring 2, several rolling elements 3 and an adjustment circle 4.
The inner peripheral surface of the outer ring 1 is provided with external groove 5, and the outer circumference surface of inner ring 2 is provided with inner groovy 6, and several rolling elements 3 are embedding It is point contact between external groove 5 and inner groovy 6, and between each rolling element 3 and external groove 5 and between inner groovy 6, i.e., should Contact between rolling element 3 and external groove 5 is two-point contact, forms one layer of groove, connecing between the rolling element 3 and inner groovy 6 Touching is also two-point contact, and friction can be reduced using four point contacts by forming another layer of groove due to having abandoned line face contact, because Generated heat can reduce when this bearing high-speed cruising, be conducive to long-time high speed rotation.
Further, adjustment circle 4 is socketed on the excircle of outer ring 1, is provided between adjustment circle 4 and outer ring 1 for adjusting The adjustment mechanism of both whole concentricity, which includes several adjusting screws 7, and the excircle annular of adjustment circle 4 is uniformly set Several adjusting holes of corresponding several adjusting screws 7 are equipped with, adjusting screw 7 screws in the excircle after corresponding adjusting hole with outer ring 1 Abut, by screwing or unscrew adjusting screw 7, the concentricity of adjustment circle 4 with outer ring 1 can be adjusted, with ensure to adjust circle 4 with it is outer The concentricity of circle 1 is in a reasonable margin of tolerance, to realize that the concentricity between bearing block and bearing is controllable, Jin Erfang Only since easy-regulating does not make bearing that swing easily occur when running at high speed and influences bearing the concentricity between bearing block and bearing Service life.
In the present embodiment, laundry machine bearing further includes two fixed plates 8, which is individually fixed in adjustment The axial two sides of circle 4, and the two sides axial with outer ring 1 fit closely.Specifically, the outer edge of two fixed plates 8 passes through respectively Holding screw 9 is fixed on the axial two sides of adjustment circle 4, and the inward flange two sides axial with outer ring 1 fit closely.In this way, 1 He of outer ring Adjustment circle 4 passes through the dual fixation of fixed plate of two sides, it is ensured that the high-speed rotating stability of bearing.
The excircle of adjustment circle 4 is socketed with the shock absorbing ring 10 for shock-absorbing damping, which includes coaxial arrangement First shock ring 11, intermediate shock ring 12 and the second shock ring 13, the first shock ring 11, the second shock ring 13 are located at centre The two sides of shock ring 12 are provided with the toroidal cavity 14 for working as a buffer in first shock ring 11, the second shock ring 13, Intermediate shock ring 12 is flexible solid torus, the connection of intermediate shock ring 12 and the first shock ring 11, the second shock ring 13 Place is provided with arc groove 15, and intermediate shock ring 12 is that integral type connect knot with the first shock ring 11, the second shock ring 13 Structure, monolithic construction are conducive to improve shock-absorbing damping effect.Here, the annular radius phase of the first shock ring 11, the second shock ring 13 Deng and be all larger than the annular radius of intermediate shock ring 12 so that shock absorbing ring 10 is formed as structure low between the senior middle school of both ends, work as bearing When in primary vibration, cushioning effect is only played by the first shock ring 11, the second shock ring 13, when bearing is in advanced vibration When, cushioning effect is played by the first shock ring 11, intermediate shock ring 12 and the second shock ring 13 jointly, bearing can be effectively reduced Vibration under high speed rotation state.
As described above, the indent in laundry machine bearing of the invention between each rolling element and the external groove of outer ring and with inner ring It is point contact between slot, reduces friction point, and then ensures that bearing generated frictional heat in high-speed cruising is lower, and It is socketed with adjustment snare on bearing top circle week, by the concentricity of the adjustable the two of regulating mechanism, to prevent bearing high speed from transporting It is swung when row, therefore the service life of laundry machine bearing of the invention is high, can be suitable for high speed rotation.
The above is only the preferred embodiment of the present invention, it is noted that those skilled in the art are come It says, without departing from the technical principles of the invention, several improvements and modifications can also be made, these improvements and modifications are also answered It is considered as protection scope of the present invention.
