Description
Technical field
The utility model relates to bearing machining and manufacturing, relates in particular to a kind of dual face seals hybrid ceramic angle contact ball bearing.
Background technique
Mill processing inner and outer ring lathe in bearing industry, because grinding accuracy requires high, generally make electricity consumption main shaft bistrique, grinding wheel speed is not from 1.8 ten thousand revs/min～80,000 revs/min etc., wherein less workpiece, because grinding wheel diameter is little, bistrique speed is higher, and along with operative workpiece size increases, in the situation that ensureing emery wheel safety speed, bistrique rotating speed reduces gradually, but ensure the running accuracy of bistrique, and can bear larger grinding load, general grinding spindle in configuration, the forward and backward paired angular contact ball bearing of P4 level that all adopts; Also the common matched bearings of matching combination with single cover bearing by spacing pad.In order to reduce the work temperature rise of bearing, generally in the housing of bistrique, (being the surrounding space of bearing outside diameter) is provided with the circulation canal of lathe cooling water, to can reduce the temperature rise of bearing, and in bearing inside, normal employing passes into oil gas, and its atomization is carried out to lubricating bearings.But, the bistrique using in the time that Bearing Grinding is processed inside and outside lasso at present, the overwhelming majority is all the P4 level angular contact ball bearing that adopts open type, although adopt above-mentioned all addition thereto, the technical barrier that makes us being entangled with that is still on the low side in working life of bistrique bearing.
Model utility content
For the present situation of above-mentioned prior art, technical problem to be solved in the utility model is to provide one can reduce friction, reduces the radial internal clearance of bearing, safety and environmental protection, the dual face seals hybrid ceramic angle contact ball bearing increasing the service life.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of dual face seals hybrid ceramic angle contact ball bearing, comprise lasso and rolling element, described lasso comprises inner ring and outer ring, between this inner ring and outer ring, be provided with dual face seals circle, there is gap in soft epipharynx and the inner ring ramped surfaces of this dual face seals circle, this gap is 0.05～0.10mm, the external diameter of this dual face seals circle is pressed in the seal groove of outer ring, described rolling element is arranged between inner ring and outer ring, and this rolling element and inner ring are combined into one by retainer.
Further, described rolling element is silicon nitride ceramic ball.
Further, described dual face seals circle is acrylate rubber seal ring.
Further, described retainer is pnenolic aldehyde bakelite holder.
Further, the internal diameter Spielpassung of the external diameter of described retainer and outer ring, this gap is 0.02～0.03um.
Compared with prior art, the utility model has the advantage of: the utility model adopts dual face seals circle to make bearing realize integral sealing, can effectively preserve oiling agent, thereby ban oil mist lubrication, alleviate environmental pollution, be conducive to direct labor's physical and mental health, in addition, adopt silicon nitride ceramic ball to replace steel ball, can reduce inertia, bearing is in the time starting or stoping rapidly, can reduce the active force that retainer bears, in the time of High Rotation Speed, because retainer is realized guiding location with outer ring internal diameter, can reduce and collide and friction, reduce bearing temperature rise, extend the operating life of oiling agent, and silicon nitride ceramic ball hardness is high, thermal expansion coefficient is little, can appropriate reduce the radial internal clearance of bearing, giving tightly of bearing strictly controlled, can improve rigidity and the running accuracy of main shaft, the in the situation that of insufficient lubrication, be difficult for stuck, easy to use, cost performance is high, long service life.

Embodiment
As shown in Figure 1-2, a kind of dual face seals hybrid ceramic angle contact ball bearing, comprise lasso and rolling element 3, described lasso comprises inner ring 2 and outer ring 1, between this inner ring 2 and outer ring 1, be provided with dual face seals circle 4, this dual face seals circle 4 is acrylate rubber seal ring, there is gap in the soft epipharynx of this dual face seals circle 4 and inner ring 2 ramped surfaces, this gap is 0.05～0.10mm, the external diameter of this dual face seals circle 4 is pressed in 1 seal groove of outer ring, described rolling element 3 is arranged between inner ring 2 and outer ring 1, this rolling element 3 is silicon nitride ceramic ball, this rolling element 3 is combined into one by retainer 5 with inner ring 2, this retainer 5 is pnenolic aldehyde bakelite holder, the internal diameter Spielpassung of the external diameter of described retainer 5 and outer ring 1, this gap is 0.02～0.03um, rolling element 3 adopts silicon nitride ceramic ball to replace steel ball, can reduce inertia, therefore bearing is in the time starting or stoping rapidly, can reduce the active force that retainer bears, in the time of High Rotation Speed, because retainer 5 is realized guiding location with outer ring 1 internal diameter, can reduce and collide and friction, reduce bearing temperature rise, extend the operating life of oiling agent, and silicon nitride ceramic ball hardness is high, thermal expansion coefficient is little, can appropriate reduce the radial internal clearance of bearing, giving tightly of bearing strictly controlled, can improve rigidity and the running accuracy of main shaft, the in the situation that of insufficient lubrication, be difficult for stuck, easy to use, cost performance is high, long service life.
Finally it should be noted that: above embodiment only, in order to the technical solution of the utility model to be described, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, it will be understood by those of skill in the art that its technological scheme that still can record aforementioned each embodiment modifies, or part technical characteristics is wherein replaced on an equal basis; And these amendments or replacement do not make the essence of appropriate technical solution depart from spirit and the scope of the each embodiment's technological scheme of the utility model.
