Abstract
The utility model relates to a bearing assembling tool, especially to a bearing resetting mould with a fixed type bottom bearing support. The utility model mainly solves the problems of the prior art. In the compacting conical roller bearing process of the prior art, a retainer will extrude a conical roller and then a conical inner ring of a bearing when the retainer is reset due to no block in the bearing inner ring and the contacts among the roller, the retainer and the inner ring and then a self-locking is generated. Thus the retainer, the roller and the inner ring of the prior art are unable to recover in an ideal state and meanwhile the extruded roller, retainer and inner ring have an impact on the bearing use precision. The utility model which comprises a bearing resetting mould (1) is characterized in that the central part of the bearing resetting mould (1) is provided with an empty chamber (2) which can accommodate a bearing inner ring. The edge of the empty chamber is provided with a plurality of roller grooves (3) which are inclined downwards. And the bottom of the empty chamber is provided with a bottom bearing support (4) which can support the bearing inner ring.
Description
Technical field
The utility model relates to a kind of assembly tool of bearing, especially relates to a kind of bearing with fixed bottom support seat mould that resets.
Background technique
The existing bearing packaging technology is after steel ball and inner ring, outer ring are assembled together, and presses two-sided retainer, cleaning, Checking of finished products, oven dry, greasing, pressure seal ring successively, goes out finished product after the assembling.Chinese patent discloses a kind of assembly bend claw mould of cylindrical roller bearing stamping retainer (notice of authorization number: CN 201301911Y), it is by tapered sleeve, pin, straight pin, spring, socket cap screw, drift, base, positioning work piece, socket cap screw, saddle, cover plate, socket cap screw is formed, saddle and cover plate are linked by socket cap screw, drift and saddle are connected by pin and are evenly distributed on the circumference of saddle, the sub-restraining spring of pin, base and positioning work piece are connected by socket cap screw, spring is installed in the positioning work piece groove under the compression of pin, tapered sleeve is that face contacts with drift, and drift is radially relatively moving with saddle.Chinese patent also discloses a kind of roller bearing lasso assembling mould (notice of authorization number: CN 201335103Y), it is by chock, retainer flanging mould and cushion block are formed, retainer flanging mould cuts into uniform quarter with the method for line cutting, cutting asks that the crack is 4-5mm, the chock conical surface is 60 degree, retainer flanging mould is placed on the cushion block, chock is placed in the retainer flanging mould, the conical surface even contact of the conical surface of chock and retainer flanging mould, chock rises by the retainer flanging mold pressing of quarter, bearing first inner ring and the connection piece bearing locking collar of axle between second inner ring are bent in the set connection groove of bearing first inner ring and axle second inner ring, make bearing first inner ring and axle second inner ring become one.But these two kinds of moulds are when the compacting tapered roller bearing, because bearing inner race is not with rib, roller, retainer, inner ring are contact condition, when retainer resets, and retainer extruding roller, push inner ring again, and because roller and inner ring are cone, stressed generation self-locking, thus make retainer, roller and inner ring all can not recover perfect condition, squeeze simultaneously and hindered roller, retainer, inner ring, influenced the bearing service precision.
The model utility content
The utility model provides a kind of bearing with fixed bottom support seat mould that resets, it mainly is to solve the existing in prior technology mould when the compacting tapered roller bearing, because bearing inner race is not with rib, roller, retainer, inner ring are contact condition, when retainer resets, retainer extruding roller, push inner ring again, and because roller and inner ring are cone, stressed generation self-locking, thereby make retainer, roller and inner ring all can not recover perfect condition, squeeze simultaneously and hindered roller, retainer, inner ring, influenced the technical problem of bearing service precision etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of bearing of the present utility model mould that resets with fixed bottom support seat, comprise the bearing mould that resets, reset mould middle part of described bearing is provided with the cavity that can put into bearing inner race, cavity edge is provided with some roller grooves, the roller groove is downward-sloping, but the bottom of cavity is provided with the bottom support seat of block bearing inner ring.In the bottom of cavity the bottom support seat is set, can be used for holding bearing inner race, make inner ring can down not drop, make can too not compress between inner ring, roller, the retainer locked, when resetting, retainer the power on the retainer is not delivered on roller and the inner ring, avoid crowded wound, and guaranteed the relative position that resets.After the inner ring of tapered roller bearing was put into cavity, roller can be put into the roller groove in turn, and the roller groove is distributed on around the cavity.
As preferably, described bottom support seat includes and can insert the reset base of mould bottom of bearing, and base top is provided with the support of block bearing inner ring, and the diameter of support is less than or equal to the diameter of bearing inner race.The support diameter makes support and base form ladder-type less than base diameter, and after the assembling of bottom support seat, base can be stuck in cavity bottom like this, and support stretches into the cavity internal support and lives inner ring.
As preferably, the reset internal surface of mould bottom of described base and bearing is an interference fit, and magnitude of interference can be controlled between the 0.05-0.15, guarantees that base is fixed on the mould that resets.
Therefore, the utility model has increased the bottom support seat in the reset bottom of mould of bearing, make it can hold bearing inner race, prevent between inner ring, roller, the retainer locked, when retainer resets, the power on the retainer is not delivered on roller and the inner ring, has avoided crowded wound, and guaranteed the relative position that resets, guaranteed bearing accuracy, simple and reasonable for structure.
