Description
Technical field
The present invention relates to crane field, refer more particularly to a kind of with outward flange seat and back-up ring by motor car wheel group.
Background technology
Cart in existing universal crane field, trolley travelling device car wheel group structure, the wheel group that the wheel mostly adopting angle box bearing housing to be connected to all size is formed; This wheel group connects a wheel by the middle of an axletree, and axletree both sides respectively connect an angle box bearing housing respectively by bearing, and each angle box bearing housing is connected to other parts a lot of as transparent cover, stifle, sleeve, backing plate and fastener thereof; And then two angle box bearing housings are connected on the bent plate of " L " shape on crane end carriage both sides, " L " v notch v that therefore corresponding specification all must be processed in every bar crane end carriage both sides, different large trundle group connects; The hoisting crane of different size, its end carriage size, length are variant, cause the communication port of every bar end carriage two ends and wheel group all must carry out nonstandard processing like this, owing to not becoming series with wheel group connecting portion, end carriage head is large again, so end carriage can not carry out continuous batch production, can not many production reservies in advance, can only carry out order, then produce end carriage and wheel group thereof according to specification, production efficiency is not high; The power of this wheel group inputs by external equipment as motor, reductor, drg and corresponding base, coupler etc. couple together in addition; Wheel group parts are many, complex structure, angle box bearing housing are cast and fine limit work bothers, space occupy-place is large, weight is large, dismounting is time-consuming, manufacturing cost is high, and wheel group running noise is large, there is obvious weak point.
Summary of the invention
The object of the invention be to overcome above-mentioned the deficiencies in the prior art part and provide a kind of with outward flange seat and back-up ring by motor car wheel group, described wheel group compact conformation, from heavy and light, parts are few, mounting or dismounting are convenient, wheel group is made into drive disk assembly that can be general, can conveniently be connected on varied equipment needing motion, of many uses.
For achieving the above object, the present invention adopts following technology to realize:
With outward flange seat and back-up ring by a motor car wheel group, comprise connecting shaft wheel 11, outward flange seat 13, joint case 22, described connecting shaft wheel two sides are equipped with the shaft extension of raised side and the little shaft shoulder; Described connecting shaft wheel is connected with two outward flange seats respectively by two bearings, and described outside race is connected in outward flange seat by cover of dust and back-up ring; The flange of described two outward flange seats is bolted the outside in joint case side; Described joint case be provided with connect elongated hole for need the equipment connection that moves.
Wherein, described outward flange seat 13 is provided with flange 134, bearing hole 132, axis hole 133, axis body 131; Described bearing hole 132 is opened in flange side, and described axis hole 133 is opened in axis body 131 side; Described bearing hole 132 also offers draw-in groove 135; Described flange partial face offers connecting bore 136.
Wherein, described connecting shaft wheel 11 can be two-wheel edge, single-wheel edge or without wheel rim.
Wherein, described joint case 22 is become the casing of all round closure by Plate Welding; Described joint case 22 one end is provided with connecting panel 220, and described connecting panel 220 edge is provided with and connects elongated hole 2201 for connecting the equipment of needs motion; The described joint case other end is provided with connecting bore 224 for connecting energy disperser; Described joint lower box part is without shrouding, and top is provided with shrouding and offers access opening 221, and two sides are provided with the open type axis hole 222 of declivity and the tapped bore 223 of Flange joint.
Beneficial effect of the present invention is: simple, compact by motor car wheel group structure, install and remove convenient, can be used as the one of enterprise or a series of universal component, joint case connects elongated hole to can be used for wheel group to be connected on the equipment of needs motion, can be used as the driving device of multi-field use, of many uses; The shaft extension on connecting shaft wheel both sides protrudes wheel face, both sides shaft extension width can wider than the inwall width of joint case, such car wheel structure can realize bearing and be arranged on sidewall center, both sides close to joint case, external load is by passing to outward flange seat, bearing under the both sides straight wall alignment of joint case, pass to wheel shaft extension again, ensure outward flange seat not by cantilever force, just connect firmly, ensure that wheel group operates steadily; The little shaft shoulder of connecting shaft wheel is used for location bearing inner ring; Be connected between flange on outward flange seat and joint case by the pad of different-thickness, just can finely tune the left and right departure distance of wheel center line, wheel bias in joint case can be alleviated cause gnawing rail problem, also can regulate the spacing degree of tightness problem of the inside and outside circle of bearing, solve wheel axial motion phenomenon; Outward flange seat can directly be extracted from joint case side, just can change bearing, whole wheel group need not be unloaded down maintenance, and therefore the flange of outward flange seat is connected to outside joint case and is conducive to keeping in repair bearing; The cover of dust that outward flange seat connects and back-up ring can easily take out, and are not dismantling in outward flange seat situation, just can check whether bearing damages; Joint upper box part is provided with access opening, steel rope is worn from access opening just can conveniently for wheel lifting when dismounting wheel, operation is just easily convenient, access opening can also be used for the fastener of inspection trolley wheels and whether bearing is installed correctly, access opening can be built with cover plate at ordinary times, dust-proof or ensure safety; Joint case side is provided with the open type axis hole of declivity for connecting outward flange seat, because wheel both sides shaft extension width can wider than the inwall width of joint case, so the connecting shaft wheel that connecting shaft wheel or shaft extension both sides assemble outward flange seat must fill from lower to upper below joint case, be bumped in open type axis hole; Connection elongated hole on the connecting panel of joint case one end is used for and the equipment connection needing to move, and elongated hole is conducive to the axial location adjusting joint case, conveniently solves wheel gnawing rail, partially rail problem; Therefore, can refer to the compact joint case that the difference large small batch production size of wheel is suitable, be connected to need on the object of transmission with the elongated hole that connects of joint case end face, the one that can be become enterprise by motor car wheel group of such the application or a series of general rotatable parts, wheel group is installed at ordinary times according to the different size groups of wheel, become series to be placed on warehouse for subsequent use, purposes is just very extensive, and when hoisting crane is produced, supporting speed is fast; And in the wheel group of prior art one by one part before the delivery of each hoisting crane, scene part one by one can only be assembled into end carriage two ends again, progress is slow; The application's is few by motor car wheel group parts, convenient, safe and reliable from heavy and light, mounting or dismounting, has novelty and practicality.
