Abstract
The utility model relates to a motor bearing device, comprising a porcelain axle center, a porcelain bearing, an elasticity ring and a bearing liner. The axle center is adapted in the axle hole of the bearing liner. The upper side and the lower side of the axle hole form the concave parts into which two porcelain bearings are put in order to provide the operating location of the axle center. One concave part of the bearing liner is provided with the porcelain bearing closely matched with the bearing liner and the other concave part is provided with the elasticity ring or is formed into the rubber ring by glue, and the rubber ring, the porcelain bearing and the bearing liner are in elasticity match. The porcelain bearing has a longer service life because of the object character of higher degree of hardness. The axle hole of the bearing liner is bigger than the axle center and the lubricating oil can be filled in the axle hole. The elasticity of the elasticity ring or the elasticity colloid can provide the effects of the automatic aligning of two porcelain bearings and the absorption shock when the bearing and the axle center rotates in order to solve the problem that the accurate aligning assemble progress is needed when two sliding bearings are assembled and good stability is maintained when the axle center rotates.
Description
Technical field
The utility model relates to a kind of motor bearing device, especially a kind of bearing that is applied to the high speed rotating on the miniature motor.
Background technique
Electric motor is the important composition part of electronic product, and motor quality quality often determines the working life of whole electromechanical equipment, the unstable normal operation that can influence entire equipment of motor operations, and motor bearing is the key that influences motor quality and working stability.Especially the running rotating speed of equipment such as radiating fan for computer, magnetic disk driver is along with the continuous increase of radiating efficiency and data processing speed demand, its employed miniature motor design bearing to running life of entire equipment, efficient, and noise control direct influence is arranged.
Conventional motor bearing branch has two kinds, and shown in Fig. 7,8, a kind of is that axle center 10a contacts with oil-impregnated bearing 20a slide relative, is generally the porous crack sintered alloy material of oil-containing, and based on copper base material matter, Related product is individually standardized in the design application.All sliding contacts in axle center periphery and bearing during its running so friction loss is big, need quite scrupulous the processing in the maintenance of lubricant oil.
Another kind of conventional motor bearing is for using two ball bearing 30a, and to use an axle bush 40a be its framework, cooperates axle center 10a to turn round.The ball bearing internal mechanism is the contact of rolling, during also individually the normalization design is used.Its subject matter is that member is many, and noise in operating is big and cost is high, and heat resistance is low, and difficulty etc. is made in miniaturization.
Summary of the invention
Because scarce limit and problem that above-mentioned conventional motor bearing has when reality is used, the inventor is engaged in the relevant cause experience for many years of high technology ceramics with the individual, and study intensively and have high strength and wear resistance performance, and the ceramic material that friction ractor is little applies on the bearing, designs a kind of brand-new motor bearing device.
Main purpose of the present utility model is to provide a kind of motor bearing device, to improve the restriction of conventional motor bearing because of oil-impregnated bearing material or ball bearing mechanism, in order to working life, running efficiency and the reduction noise that bearing produced that promotes bearing.
Secondary objective of the present utility model is to provide a kind of motor bearing device, after improving the upright two porcelain bearings of the inner group of axle bush, can't admit of the technical bottleneck that error exists on group is halted the position as conventional ball bearings.
For reaching above-mentioned purpose, the utility model includes: porcelain axle center, porcelain bearing, elasticity circle body and axle bush; Described axle center is matched with in the axis hole of axle bush, the upper and lower of this axis hole is formed with reentrant part and puts into two porcelain bearings so that running location, axle center to be provided, this axle bush one side's reentrant part and insert flexible circle body or cushion rubber between between bearing and axle bush, this elasticity circle body can be the flexible rubber ring of tool fixed shape or the cushion rubber that forms in the gluing mode in the upright process of group, or design is press-fitted form with spring and produces its elasticity fixing effect; The porcelain bearing is because of the higher rerum natura of its hardness wear resistance performance, with iron system or copper be the holding load that the sliding bearing comparison of metal can improve per unit area, is provided better working life.The central axis hole place of axle bush can be in axis hole place filling lubricant oil greater than the axle center, and reaching on average provides front and back two bearings running lubricated effect, and splendid guarantor's oil effect is arranged.But the sliding bearing of upright two the tool precision-fit sizes of group has quite high technical and difficulty, be different from the monomer oil-containing alloy bearing of traditional type or have the ball bearing that a dead axle reaches the tolerance permissibility partially, so structurally need consider actual enforceable innovative design.
Thereby the utility model is in design compared with prior art, has following improvement and beneficial effect:
The utility model is because insert two porcelain bearings in the reentrant part up and down of axle bush, make wherein a porcelain bearing and axle bush for closely cooperating, therefore assembly rear bearing and axle bush do not have relative displacement and loosening situation generation, can provide the axle center stable in the running locating function; Insert between another porcelain bearing and axle bush that flexible circle body or gluing are formed with cushion rubber and axle bush is a resilient engagement, therefore the axle center is in two bearings during service firing, absorb and proofread and correct its little offset and reach the required concentricity of its smooth and easy running by the elasticity that elasticity circle body or cushion rubber possessed, and has the effect of self-aligning, and adopt resilient engagement to have simultaneously and absorb running vibrations and splendid guarantor's oil effect, solve two slip porcelain bearings and need accurate assembling process requirement, and can keep good stable when the axle center is rotated the heart.
The order of the utility model combination, because insert the axis hole of axle bush earlier with the axle center, the reentrant part of again two bearings being inserted the axle bush upper and lower cooperates with the axle center, so have the effect of center contraposition in the combination.
