Abstract
The utility model relates to a sealing member, in particular to a special sealing device for a rolling bearing, which comprises a bearing end sleeve and a bearing end ring, a bearing pedestal hole and an end sleeve shaft hole which are coaxial and penetrating are arranged on the bearing end sleeve axially, the diameter of the bearing pedestal hole satisfies the condition of interference fit with the matched bearing outer ring, and the diameter of the end sleeve shaft hole satisfies the condition of clearance fit with the matched shaft. A bearing pedestal for storing lubricating grease is arranged to maintain the lubrication state of the bearing, thereby sealing the bearing with the outside, preventing dust and corrosive gases from entering, effectively maintaining the cleanness of the bearing and the lubricating grease, extending the service cycle of the bearing, and saving running and overhaul costs.
Description
Technical field
The utility model relates to a kind of sealing component, the special-purpose seal arrangement of particularly a kind of rolling bearing.
Background technique
Bearing is a power equipment indispensable accessory, particularly rolling bearing, and is low at load because friction factor is low, is used widely on the light and handy equipment that moves.Rolling bearing generally is made up of inner ring, outer ring, rolling element and retainer, wherein the effect of inner ring is to match with axle, and rotate together with the axis, the outer ring effect is to match with bearing support, play a supportive role, rolling element is uniformly rolling element to be distributed between inner ring and the outer ring by means of retainer, because be rolling friction, friction factor is lower.In general, guarantee that rolling bearing can effectively reach operation reliably, must have fully and lubricate, prevent to take place between rolling element, raceway and the retainer directly contact, simultaneously, oiling agent can also prevent to wear and tear and protect the surface of bearing to avoid corrosion.Thus, the type of oiling agent and consumption are to need one of factor of considering in the design bearing.And bearing in use, because mechanical aging and contamination build-up, the oiling agent in the bearing configuration can slowly lose its lubricating functions, as untimely replacing lubricant grease, can cause damage of bearings.Some equipment particularly, such as unpowered blower fan, because load is low, rotating speed is not high, bearing does not have special-purpose seal arrangement, and working environment common relatively abominable (dust, corrosive gas etc.), cause the friction factor of fan bearing too high easily, make whole blower fan to seize up, even cause damage of bearings, reduce the running time of blower fan, increase frequency of maintenance, thereby increase operating cost.
Therefore, need the special-purpose seal arrangement of a kind of rolling bearing, can store lubricating grease, make bearing lubrication, guarantee bearing and extraneous sealing, avoid dust and corrosive gas to enter.
The model utility content
The purpose of this utility model is to provide a kind of rolling bearing special-purpose seal arrangement, setting can store the bearing support of lubricating grease, make bearing keep lubricating status, can guarantee bearing and extraneous sealing, avoid dust and corrosive gas to enter, effectively keep the cleaning of bearing and lubricating grease, prolong the bearing life cycle, save the operating cost and the cost of overhaul.
The special-purpose seal arrangement of rolling bearing of the present utility model, comprise bearing end cover and bearing end ring, described bearing end puts bearing saddle bore and end cover axis hole coaxial and that connect is set vertically, the diameter of described bearing saddle bore satisfies and the bearing outer ring interference fit that is cooperated, and the diameter of end cover axis hole satisfies and institute's fitted shaft Spielpassung; Described bearing end ring is provided with the end ring axis hole, and the bearing saddle bore side that the bearing end ring is arranged at bearing end cover is fixedlyed connected with bearing end cover, described end ring axis hole with hold that to overlap axis hole coaxial.
Further, described bearing end ring is the flange plate shape, and the bearing end ring of flange plate shape and at least two axial attachment holes of the bearing end cover uniform in a circumferential direction setting of opposing end surface are undertaken fixedly connected by bolt; Further, described bearing end ring is a bearing end cover, and the bearing saddle bore side of diaxon socket end cover is relative, and at least two axial attachment holes of the uniform in a circumferential direction setting of opposing end surface are undertaken fixedly connected by bolt.
The special-purpose seal arrangement of rolling bearing of the present utility model, setting can store the bearing support of lubricating grease, make bearing keep lubricating status, can guarantee bearing and extraneous sealing, avoid dust and corrosive gas to enter, effectively keep the cleaning of bearing and lubricating grease, avoid corroding, prolong the bearing life cycle, save the operating cost and the cost of overhaul; During use, bearing end cover and bearing outer ring interference fit, so the utility model also plays the effect of supporting and guaranteeing balance movement; Annular maze trough is set, is full of lubricating grease in the groove, further strengthen sealing effect, the rubbing surface that minimizing may exist makes equipment operation smooth and easy; Bearing saddle bore and end cover axis hole excessively place are provided with chamfering, after the installation shaft, form the cavity that can store lubricating grease between chamfering and the axle, can supplemental lubrication fat to bearing, be beneficial to raising service cycle.
