The chain sprocket structure of fast changeable
Affiliated technical field
The utility model relates to a kind of drive sprocket of trough conveyor of suitable high temperature heavy load divided solid materials conveying equipment, particularly relates to a kind of chain sprocket structure of the trough conveyor that is convenient for changing.
Background technique
Trough conveyor is that a kind of alumina factory burns till the equipment that the workshop is used to carry alumina clinker.This equipment is because dust pollution makes work under bad environment, to making drive sprocket wheel toothed portion serious wear in the transmission system, be illustrated in figure 1 as the drive system structure schematic representation of existing trough conveyor, when initiatively the gear teeth of whole sprocket wheel 7 may wear to a certain degree, this equipment can not normally use, and must change sprocket wheel this moment.The drive sprocket of traditional trough conveyor is an overall structure, as shown in Figure 2, needs integral body to split out whole sprocket wheel 7 during replacing.Want to split out sprocket wheel and must at first split out the part that is associated with it, i.e. drive chain, coupling, bearing support, bearing 8 etc., sprocket wheel could be unloaded down from transmission shaft 6.Whole maintenance process labor intensity is big, expense is high, service cycle is long.
The model utility content
Technical problem to be solved in the utility model is: the chain sprocket structure that a kind of novel fast changeable is provided, purpose is to solve drive chain that trough conveyor needs to be associated with sprocket wheel, coupling, bearing support, bearing etc. to remove earlier when the maintenance sprocket wheel, makes the technical problem that whole maintenance process labor intensity is big, expense is high, service cycle is long.
In order to solve the problems of the technologies described above, the utility model is achieved in that the chain sprocket structure of fast changeable, and it comprises the gear teeth and wheel Hub, and wherein the gear teeth and wheel hub are for dividing body structure, and the gear teeth are embedded on the wheel hub.
The described gear teeth are to be embedded on the wheel hub by hold-down ring, fixing bolt.
The described gear teeth are that a plurality of monodentates are embedded on the wheel hub.
The described gear teeth are that multiple tooth grouping is embedded on the wheel hub.
The described gear teeth are made up of two groups or more parts.
Advantage of the present utility model and effect are as follows:
The utility model only need be taken bolt, nut apart, and need not to change wheel Hub part because with the gear teeth and hub design composition body structure, the gear teeth are embedded on the wheel hub behind the wheel odontotripsis, just can change the gear teeth easily.This not only reduced service worker labor intensity, reduced the manufacture cost of accessory, also shorten service cycle greatly, improved the running rate of equipment simultaneously.The gear teeth have symmetry properties on the longitudinal cross-section, after a lateral wearing is serious, can change the stress surface of the gear teeth by different mounting types, increase the working life of one times on the gear teeth.The utility model has thoroughly changed the mode of the back of sprocket wheel wearing and tearing in the past integral replacing.

Among the figure, 1, bolt, 2, nut, 3, the gear teeth, 4, hold-down ring, 5, wheel hub, 6, transmission shaft, 7, whole sprocket wheel, 8, bearing.
Embodiment
Be described in further detail below in conjunction with 3 pairs of the utility model of accompanying drawing, but protection domain of the present utility model is not limit by embodiment.
As shown in Figure 3, the trough conveyor sprocket wheel is the split composite structure.Its concrete structure is as follows: it comprises the gear teeth 3 and wheel Hub 5, and the gear teeth 3 are the branch body structure with wheel hub 5, and the gear teeth 3 are embedded on the wheel hub 5 by hold-down ring 4, fixing bolt 1, nut 2.The gear teeth 3 can be that a plurality of monodentates are embedded on the wheel hub 5, also can be that multiple tooth grouping is embedded on the wheel hub 5.
The above-mentioned gear teeth 3 can be made up of two groups or more parts.When the gear teeth 3 were changed in maintenance, only need take bolt 1, nut 2 apart just can unload the gear teeth 3 parts easily.The gear teeth 3 have symmetry properties on the longitudinal cross-section, after a lateral wearing is serious, can change the stress surface of the gear teeth 3 by different mounting types, increase the working life of one times on the gear teeth.
