The single, double beam crane end carriage of electric block wheel
Technical field
The utility model relates to the hoisting crane technical field, is specifically related to the single, double beam crane end carriage of a kind of electric block wheel.
Background technology
In weight-lifting equipment, overhead crane with electric hoists is compact with its overall dimensions, from advantages such as heavy and light, wheel load are little, by wide model, applied.And not enough for it, the ground-engaging element of this series products---wheel group have overall dimensions large, from many defects such as great, that load-carrying capacity is little, installation is inconvenient, structure is not attractive in appearance.Traditional wheel group is complex structure not only, and the connection structure of itself and end carriage is unstable, adopted the design on interior gear edge due to its bear box simultaneously, make the installation of this wheel group bother, waste time and energy, and the inboard oral area of bear box endoporus is bolted inboard roller bearing end cap, when it needs to change wider wheel on being assembled to different hoisting cranes, the inboard easy and wheel generation grazing of bear box, it certainly will will widen end carriage, thereby cause the oad of end carriage larger, strengthen the deadweight of hoisting crane.
The utility model content
It is a kind of simple in structure that technical problem to be solved in the utility model is to provide, the single, double beam crane end carriage of the electric block that result of use is good wheel.
Technical problem to be solved in the utility model realizes by the following technical solutions:
The single, double beam crane end carriage of a kind of electric block wheel, comprise a wheel body, it is characterized in that: described wheel body center is provided with axis hole, two ends at described wheel body axis hole are provided with bearing, the excircle at described wheel body two ends is provided with rib, and a rib excircle is provided with the gear teeth therein.
Described wheel body is made by metallic material.
Rib on the described gear teeth and wheel body is structure as a whole.
The beneficial effects of the utility model are: the utility model is simple in structure, and hardness is good, can meet the operation needs of multiple hoisting crane, long service life, stable and reliable operation.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, the single, double beam crane end carriage of a kind of electric block wheel, comprise a wheel body 1, wheel body 1 center is provided with axis hole, two ends at wheel body 1 axis hole are provided with bearing, and the excircle at wheel body 1 two ends is provided with rib 2, and rib 2 excircles are provided with the gear teeth 3 therein, wheel body 1 is made by metallic material, and the gear teeth 3 are structure as a whole with the rib 2 on wheel body 1.Wheel body 1 can adopt the 45# forging to make and form, and surface hardening hardness can reach more than 50.
Above demonstration and described groundwork of the present utility model and principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification sheets, describes just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
