Abstract
The utility model relates to a sealed astragal absorbing deep groove ball bearing, this deep groove ball bearing include bearing inner race, bearing inner race, holder, steel ball, reinforced seal circle, and through holder connection steel ball between bearing inner race and the bearing inner race, the reinforced seal circle is connected to the both sides of groove room between bearing inner race and the bearing inner race, its design point lies in wherein one side reinforced seal circle outside disjunctor is equipped with and is annular shock pad, and shock pad one side with correspond the bearing inner race terminal surface offsets sealedly. Through enclosing the disjunctor setting with the shock pad with reinforced seal to guaranteeing that the shock pad mounted position is concentric, simplifying the installation, during the use, the bearing can played a supporting role, can play axial cushioning effect again, and it is comparatively convenient to use, and work is comparatively reliably stabilized. Be fit for using as the shock attenuation reinforced seal circle of bearing, or the institutional advancement of like product.
Description
Technical field
This utility model relates to bearing, is a kind of deep groove ball bearing sealing astragal damping.
Background technology
The dustproof construction of existing bearing, usually uses bearing sealed ring, uses contact or non-contact seal ring according to use occasion, working environment and the motor speed of bearing.Bearing sealed ring, in being generally used for preventing bearing, oils and fats overflows and prevents extraneous dust from entering, and plays dust seal effect.Existing bearing sealed ring is typically made up of skeleton and rubbery sealed body, and skeleton is wrapped in rubber bodies completely, and this sealing ring has good sealing property.User is when installing bearing, in order to reduce axial vibrations during motor rotation, in bearing block, often first load a yielding rubber pad, bearing is installed the most again, so advantageously reduce the axial vibration impact of motor, but owing to yielding rubber pad is relatively thin, easily misplace during installation, cause installation site the most concentric with axle center, impact assembling and using effect.To this end, need existing bearing seal structure is improved.
Summary of the invention
For overcoming above-mentioned deficiency, the purpose of this utility model is to provide a kind of deep groove ball bearing sealing astragal damping to this area so that it is solves existing similar bearing and does not have axial damping, or axial damping structure installs more inconvenience, the technical problem of less effective.Its objective is to be achieved through the following technical solutions.
The deep groove ball bearing of this reinforced seal astragal damping performance includes bearing inner race, bearing outer ring, retainer, steel ball, backbone sealing ring, steel ball, the both sides connecting framework sealing ring of groove room between bearing inner race and bearing outer ring is connect by retainer between bearing inner race and bearing outer ring；Its structural feature is that wherein disjunctor is provided with cushion ringwise outside backbone sealing ring described in side, and cushion side offsets with corresponding described bearing outer ring end face sealing.By being arranged with backbone sealing ring disjunctor by cushion, thus ensureing that cushion installation site is concentric, simplify and install, during use, bearing can be played a supporting role, and can play again axial cushioning effect, use more convenient, works the most reliable and stable.
The side of described bearing outer ring is provided with and the cannelure of described cushion location fit.By this structure, prevent cushion radial shape variable displacement, improve the reliability installed, use.Same, also can the side of described bearing outer ring be provided with and the groove of described cushion location fit, described cushion is provided with the protuberance with groove fit, can realize identical purpose.
Form the cavity of and described bearing outer ring location fit between outside described cushion and described backbone sealing ring, bottom cavity, form an arc-shaped notch with described cushion root connecting position.By this arc-shaped notch, make cushion the most reliable with the laminating of bearing outer ring end face, closely.
The end-play of 0.015～0.021mm it is provided with between described bearing inner race and bearing outer ring.End-play between described bearing inner race and bearing outer ring is set to 0.015～0.021mm, makes bearing be applicable to more high-revolving use requirement.
This utility model structure is relatively simple, manufactures processing more convenient, low cost, deep groove ball bearing is not only made to have the effect of dust seal, can take into account again the requirement of axial damping, the damping backbone sealing ring being suitable as bearing uses simultaneously, or the structure of like product is improved.

Sequence number and entitled in figure: 1, bearing inner race, 2, bearing outer ring, 201, cannelure, 3, retainer, 4, steel ball, 5, backbone sealing ring, 501, cushion, 502, cavity, 503, arc-shaped notch, 6, bearing block.
Detailed description of the invention
In conjunction with accompanying drawing, this utility model is further described.
As Figure 1-Figure 2, the deep groove ball bearing of this sealing astragal damping includes bearing inner race 1, bearing outer ring 2, retainer 3, steel ball 4, backbone sealing ring 5, steel ball, the both sides connecting framework sealing ring of groove room between bearing inner race and bearing outer ring is connect by retainer between bearing inner race and bearing outer ring.Wherein outside the backbone sealing ring of side, disjunctor is provided with cushion 501 ringwise, and this disjunctor molding is to use special mould and vulcanizing equipment to complete.Cushion side forms, with respective shaft bearing outer-ring end face, the sealing that offsets.The end face of bearing outer ring is provided with the cannelure 201 with cushion location fit so that cushion is limited in cannelure, reduces cushion radially deformation, it is ensured that axial damping effect reliably.Also can the side of bearing outer ring be provided with and the groove of cushion location fit, cushion is provided with the protuberance with groove fit, can play equally and prevent cushion radially deformation, it is ensured that axial damping effect reliably.In order to make the laminating of cushion and bearing outer ring end face the most smooth, reliable, outside cushion and backbone sealing ring between form the cavity 502 of and bearing outer ring location fit, with cushion root connecting position one arc-shaped notch 503 of formation bottom cavity.In order to make bearing be more suitable for high-revolving use requirement, such as: the rotating speed of motor of dust collector is generally 2～30,000 turns per minute, and in order to adapt to such rotating speed, the end-play between bearing inner race and bearing outer ring is set to 0.015～0.021mm.
As it is shown on figure 3, be the deep groove ball bearing of this sealing astragal damping and the structural representation of bearing block 6 assembling, wherein cushion plays cushioning effect between bearing outer ring and bearing block.
Above content is intended to illustrate technological means of the present utility model, and unrestricted technical scope of the present utility model.Those skilled in the art combine existing common knowledge and do this utility model conspicuously improved, within also falling into this utility model scope of the claims.
