Description
Technical field
The utility model relates to crane facility field, is specifically related to a kind of crane locomotive wheels.
Background technology
Wheel group is used to carrying crane and load, and back and forth travels the device run in orbit.Wheel group comprises wheel, axletree, is installed on the bearing being positioned at wheel both sides on axletree and bear box, and the version of wheel group mainly divides according to the structure of bearing brackett, is divided into angle case structure and 45 degree of split type structures.45 degree of dissection type wheel groups comprise two semi-rings, and the interface between two semi-rings is horizontal by 45 degree of angles.Adding man-hour, the semi-ring of bearing brackett is being welded on trolley frame or cart end carriage, the fitting surface of overall processing semi-ring and bear box annulus, to ensure wheel assembly precision and the level of wheel, vertical, measure of skewness.Wheel group is installed in the bearing brackett processed, completes the assembling of wheel group.The periphery being set in the bear box outside bearing generally has annular groove, there is inside the semi-ring of bearing brackett the semi-circular boss of the annular groove adaptation of bear box, when two semi-rings of bearing brackett interlock, bear box is clipped in the middle, the semi-circular boss of semi-ring is in the annular groove of bear box, bear box is played to the effect of axial limiting, the both ends of semi-ring are provided with two bolt mounting holes side by side, and two semi-rings are fixed by bolt.Because the bolt hole distance wheel face on the semi-ring of wheel side is nearer, there is no the space of enough tool activity confession tighting a bolt, not only be inconvenient to twist bolt, reduce the efficiency of assembling of wheel group, and can be not easy bolt tightening, if bolt is twisted not tight, wheel run-off the straight, the phenomenon of rail can be gnawed, worn wheels, also be unfavorable for the normal operation of hoisting crane.
Summary of the invention
The purpose of this utility model is to provide a kind of crane locomotive wheels, joins inefficient technical matters to solve wheel assembling.
To achieve these goals, the utility model adopts following technical scheme: a kind of crane locomotive wheels, comprise wheel, axletree, the bear box being positioned at the wheel left and right sides be sheathed on axletree, bear box periphery has annular groove, bearing brackett is arranged with outside described bear box, described bearing brackett comprises two symmetrically arranged semi-rings, described semi-ring is installed in the annular groove of bear box, there is in the middle part of the two ends of described semi-ring a bolt hole respectively, there is between described bolt hole to wheel side wall the distance for adaptive bolt disassembly tool activity.
The annular groove of the width on the left and right directions of described semi-ring and bear box is adaptive.
Be provided with pad between two semi-rings of described bearing brackett, described pad has the through hole corresponding with the bolt hole of semi-ring.
Described axletree is arranged with for the axle sleeve to bearing axial limiting between wheel and bear box.
The left and right sides of described bear box has been bolted to connection roller bearing end cap.
The beneficial effects of the utility model are: the bolt hole of the semi-ring end of bearing brackett is set to one, one end by the utility model, and bolt hole is in the medium position of semi-ring end, when two semi-rings being fixedly connected with by bolt, be inserted between bolt in bolt hole and wheel side wall and there is enough gaps, to ensure the space of the tool activity of assembling-disassembling bolt, facilitate tightening of bolt, improve the efficiency of assembling of wheel group.
Accompanying drawing explanation
Fig. 1 is the front view of embodiment of the present utility model;
The A-A cutaway view of Fig. 2 Fig. 1.
Detailed description of the invention
The embodiment of a kind of crane locomotive wheels of the utility model, as shown in Figure 1-2: comprise axletree 3, the wheel 1 be connected to by key 9 on axletree 3, the bearing 7 being positioned at wheel 1 left and right sides be sheathed on axletree 3, bear box 5 is arranged with outside bearing 7, bear box 5 periphery has annular groove 51, and the left and right sides of bear box 5 has been bolted to connection roller bearing end cap 6.Axletree 3 is arranged with between wheel 1 and bear box 5 for the axle sleeve 8 to bearing 7 axial limiting, axle sleeve 8 one end and wheel 1 sidewall contact, the other end of axle sleeve 8 and the inner ring top force fit of bearing 7.Bearing brackett is arranged with outside bear box 5, bearing brackett comprises two symmetrically arranged semi-rings 2, angle between the contact surface of two semi-rings 2 and horizontal surface is 45 degree, semi-ring 2 is installed in the annular groove 51 of bear box 5, the A/F of the annular groove 51 of the width on the left and right directions of semi-ring 2 and bear box 5 is suitable, and semi-ring 2 has the through semicircle orifice in left and right, for convenience of processing, semicircle orifice is unthreaded hole, instead of stepped hole.There is in the middle part of the two ends of semi-ring 2 bolt hole 21 respectively, there is between bolt hole 21 to wheel 1 sidewall the distance for adaptive bolt disassembly tool activity.
Wheel group when mounted, first by wheel 1, axle sleeve 8, bearing 7, bear box 5 and roller bearing end cap 6 are assemblied on axletree 2 successively, a semi-ring 2 in bearing brackett to be first welded on the trolley frame of hoisting crane or the end carriage of cart, the axletree assembled is arranged on semi-ring 2, make the annular groove 51 of bear box 5 corresponding with semi-ring 2, semi-ring 2 is stuck in the annular groove of bear box 5, another semi-ring of bearing brackett is being buckled on bear box 5, make the bolt hole 21 of two of bearing brackett semi-rings relative, pad is provided with between two semi-rings 2, pad has the through hole corresponding with bolt hole, finally by bolt 4 inserting bolt hole 21, two semi-rings are fixedly connected with, complete the installation of wheel group.The effect arranging pad is that bear box can be fixed by two semi-rings tightly, and thrust is larger.
In the present embodiment, the A/F of the width on the left and right directions of semi-ring and the annular groove of bear box is suitable, semi-ring has the through semicircle orifice in left and right, compared with the semi-ring that there is semi-circular boss with existing inner side, eliminate the operation of processing semi-circular boss, easy to process, improve work efficiency, and make the narrowed width of semi-ring, decrease material, reduce cost; In other embodiments, semi-ring also can adopt inner side to be provided with the structure of semi-circular boss.
