The technical solution of the utility model is: a kind of end girders of overhead traveling crane, the web that comprises both sides, bridge joint is at the top board of two webs upper ends and be installed in set of wheels on the web, described set of wheels comprises wheel, axletree and be installed in the bear box of wheel both sides, described each bear box includes cylindric casing, corresponding set of wheels offers the mounting groove that card is joined described set of wheels respectively in the end at described two web two ends, the outer peripheral face of described each bear box casing is installed in the cooresponding mounting groove, described mounting groove for along the end carriage web laterally or the U-shaped mounting groove of vertically offering, the notch correspondence of this U-shaped mounting groove is opened in end carriage by by the edge of the end of length direction or near on the base of end, radially extend on the outer face of described each casing and be provided with square flange, square flange is connected by the bolt connecting hole offered on it and the end carriage web of bolt and U-shaped mounting groove periphery.
Radially be provided with annular groove at described bear box endoporus near on the inwall of bearing outer face, in this endoporus, be provided with cover of dust by the back-up ring that is fastened in the annular groove.
Corresponding bearing radially offers oil groove in the endoporus of described bear box, is provided with the oil nipple that is communicated with oil groove in internal hole of parts on the outer wall of bear box.
The bearing of installing in described bear box is the aligning roller bearing.
The shaft shoulder on the described axletree and the core wheel of wheel are wide, are respectively arranged with the axle sleeve that cooperates, is used for wheel alignment with the bearing inner ring roof pressure in the both sides of wheel.
The periphery of described axle sleeve is provided with the step surface towards bearing, is folded with dust slinger between the step surface of this axle sleeve and bearing.
Set of wheels is installed on the U-shaped mounting groove of offering on the end carriage web in the utility model, and passes through square flange and end carriage bolted connection that the bear box outer face is provided with, and it is simple in structure, easy for installation, and its mounting connection structure is stable; Simultaneously, because being set on the outer face of its bear box, flange constitutes outer retaining along structure, make structure rationalize more, can reduce the gap between bear box and the wheel, thereby reduced the axial dimension of bear box, made the axial dimension of whole set of wheels and the end carriage oad that cooperates with it reduce simultaneously, reduced the deadweight of end carriage and hoisting crane, save the material of hoisting crane, reduced the manufacturing cost of hoisting crane; Simultaneously, end carriage structure for hoisting crane, adopt the wheel of different-diameter, its axial installation dimension is identical, the width that is end carriage is constant, only needs the height of change crane end carriage web or the thickness of end carriage top board to get final product, and has strengthened the characteristics of set of wheels unit design interchangeability greatly, improve the efficient of producing, reduced the manufacturing and the maintenance cost of hoisting crane; And, greatly reduce wheel tread from the space to the roof height, can reduce the building clear headroom, save cost of investment.
