A kind of two flange linear bearing assembly, comprise bearing housing, linear bearing, mounting hole is provided with in bearing housing, linear bearing loads in mounting hole, one end of bearing housing is provided with the first flange, first flange is provided with axis hole, it is characterized in that, described bearing housing and the first flange are integral type structure, the aperture of described axis hole is less than mounting hole, tapered structure outside the two ends of described linear bearing, described linear bearing and mounting hole Spielpassung, the joint of mounting hole and axis hole is provided with conical limit face, the outer end of described bearing housing is arranged with the second flange, the end face of the second described flange extends to form connecting sleeve, be threaded between connecting sleeve with bearing support, the tapered structure of inner ring of connecting sleeve, the conical surface at linear bearing two ends respectively with conical limit face, connecting sleeve inner ring taper-face contact is spacing.
The two ends of linear bearing are spacing by two conical surfaces, as long as ensure that the machining accuracy of two conical surfaces and assembly precision just can ensure linear bearing and the first flange, the coaxality of the second flange, mounting hole Spielpassung in linear bearing and bearing housing, exactly for finely tuning coaxality, during installation, first linear bearing is loaded in bearing support, then axle is passed linear bearing, finally connect the second flange, connecting sleeve is the continuous whole linear bearing assembly that slides in the process of tightening, experience the resistance that linear bearing is subject to, finally adjust to suitable resistance, when after stop collar and linear bearing ends contact, continue to tighten, the fit tolerance of finely tuning linear bearing and axle can be realized, in the using process of this kind of linear bearing assembly, friction between ball and axle is even, axle, ball is not fragile.
As preferably, the side of described connecting sleeve is provided with locking bolt.After connecting sleeve is adjusted to optimum position, lock stop collar by locking bolt.
As preferably, be provided with the first seal ring in the axis hole of the first flange, the endoporus place of the second flange is provided with seal ring mounting groove, is provided with the second seal ring in seal ring mounting groove.First seal ring, the second seal ring play the effect of waterproof and dustproof, improve the working life of linear bearing.
As preferably, the first seal ring, the second seal ring cross section are E font, and storing in the cavity in the first seal ring, the second seal ring has lubricant grease.There is three seals lip, good sealing effect in the seal ring of E font, forms cavity simultaneously, store lubricant grease in cavity between close adjacent two seals lip, reduces the surface friction drag between ball and axle.
As preferably, be provided with shoe cream room between the second seal ring and the outer end of linear bearing, the side of described connecting sleeve is provided with the oil hole be communicated with shoe cream room, and the outer end of oil hole is provided with plug cock.Oil injection operation can be carried out when not dismantling linear bearing to the ball of linear bearing, plug cock beyond the Great Wall after oiling, ensureing the working life of linear bearing.
Therefore, the utility model has and ensures that linear bearing and flange coaxiality are high, reduces ball in linear bearing and weares and teares, the beneficial effect of long service life.
