Description
Technical field
The utility model relates to linear bearing technical field, particularly relates to a kind of extended type linear bearing assembly.
Background technique
Linear bearing is for realizing the conventional component of straight line fortune merit in machinery, generally, linear bearing cannot directly be connected with workpiece, need to be connected with component by flange, linear bearing is standard piece, the model of linear bearing is generally selected as required during use, but it is local at some, the internal diameter of linear bearing meets the demands, and the length of linear bearing is too short, when cannot meet the demands, direct buying extended type linear bearing, extended type straight line price is higher on the one hand, when extended type linear bearing is connected with bearing housing on the other hand, the axis of linear bearing, the bearing of bearing housing also more lengthens, coaxial precision is difficult to ensure more, the moving influence of coaxality and linear bearing also more strengthens, extended type linear bearing will be caused so easily to damage.
Model utility content
The utility model, in order to solve the aforementioned problems in the prior, provides coaxality between a kind of linear bearing and bearing housing high, reduces ball wearing and tearing in linear bearing, the extended type linear bearing assembly increased the service life.
To achieve these goals, the utility model adopts following technological scheme:
A kind of extended type linear bearing assembly, comprise two bearing housings, be located at the linear bearing in bearing housing, Spielpassung between linear bearing and bearing housing endoporus, the outer end of bearing housing is provided with flange, annular connecting base is provided with between the inner of two bearing housings, the interior outer end of hole of bearing housing is provided with conical limit face, the tapered structure in two ends of linear bearing, the inner of described bearing housing extends to form taper butt joint ring, the two ends of described annular connecting base are arranged with the taper butt hole coordinated with taper butt joint ring, the inner outer ring of described bearing housing is provided with connecting ring, between connecting ring with annular connecting base, bolt is connected, packing ring is provided with between the inner of two linear bearings and annular connecting base.
Connected by annular connecting base between two bearing housings, the taper butt joint ring of bearing housing the inner docks with the taper butt hole at annular connecting base two ends, thus ensure, between two bearing housings, there is good coaxality, two linear bearings are respectively charged into after in bearing housing, by bolt two bearing housing pre-connections, axle is successively through two linear bearings, then lock bolt, due to Spielpassung between linear bearing and bearing housing, thus make linear bearing can finely tune automatic adjustment axis in locking process, ensure the high with the coaxality of axle of two linear bearings, after bolt is locked completely, packing ring compresses linear bearing, prevent linear bearing from rocking, namely such one side meets the length requirement of linear bearing, farthest ensure linear bearing and axle simultaneously, coaxality between flange, improve the working life of linear bearing assembly.
As preferably, described packing ring is copper washer.Copper washer material is softer, there is small pressure elasticity, thus prevent linear bearing end wear, simultaneously, bolt is in locking process, linear bearing end can produce small impression on copper washer surface, and positioning action is played again in the end of this impression to linear bearing, prevents linear bearing from rocking in axle sleeve.
As preferably, between the both sides of annular connecting base and two connecting ring inner side surfaces, be provided with gasket seal.Gasket seal plays seal action, prevents moisture, dust from entering in linear bearing from the joint of bearing housing.
As preferably, the endoporus place of adpting flange is provided with seal ring, and described seal ring cross section is E font, and storing in the cavity in seal ring has lubricant grease.Seal ring effectively prevents outside moisture, dust from entering in linear bearing from flange endoporus, seal ring is E character form structure simultaneously, comprise three seals lip, good sealing effect, lubricant grease can store in the groove in seal ring, keep the lubrication between linear bearing ball and axle, improve working life.
Therefore, the utility model has and ensures that linear bearing and flange, axle coaxality are high, reduce ball in linear bearing and wear and tear, the beneficial effect increased the service life.
