Abstract
The utility model discloses a dismantlement formula sprocket, including sprocket seat (2) that is equipped with the centre bore, be equipped with keyway (5) in the centre bore of sprocket seat (2), be equipped with protruding rank (4) even as an organic whole on sprocket seat (2), protruding rank (4) are gone up the fixed wheel body that is equipped with at least by two fan-shaped wheel bodies (3, 6) and constitute, and the excircle of fan-shaped wheel body (3, 6) is equipped with the external tooth, connects through negative and positive draw-in groove (8) between fan-shaped wheel body (3, 6). After the structure is adopted, when the chain wheel is worn and needs to be replaced, only the fan-shaped wheel bodies (3 and 6) need to be replaced, the rear wheel and the rear wheel seat do not need to be disassembled, and the problem of difficulty in repairing due to the wear of the chain wheel is solved; has the characteristics of simple structure, convenient repair, cost saving and the like.
Description
One, technical field
The invention relates to a kind of sprocket wheel, the demountable disassembly-type sprocket wheel of particularly a kind of wheel body.
Two, background technique
Tricycle generally adopts sprocket wheel and chain to carry out transmission at present, and drive sprocket drives driven sprocket by chain and comes powered vehicle to travel, and sprocket wheel is the easily damaged parts of tricycle, adopts linking body structure, just needs whole replacing behind the use certain hour; Particularly motor-driven and electro-tricycle, when different load or different road conditions, the deformation difference that Steel Spring Plate takes place, distance between motor and the rear-wheel spindle changes, when chain will occur when pine tight phenomenon, cause the external tooth of chain and sprocket wheel to produce heel and toe wear, shortened chain and sprocket wheel normal working life greatly, its transposing frequency is higher; The chain transposing is more convenient comparatively speaking, just change quite trouble and be contained between the trailing wheel driven sprocket on the rear-wheel spindle, after at first trailing wheel and rear wheel seat will being disassembled, can dismantle the sprocket wheel on the rear-wheel spindle, need load onto trailing wheel and rear wheel seat again again after changing, be assigned a new job time-consuming again the effort, it is very inconvenient to dismantle.
Three, summary of the invention
In order to overcome the above defective that existing sprocket wheel exists, the invention provide a kind of sprocket wheel wearing and tearing back only need change wheel body, cost low, change disassembly-type sprocket wheel easily.The invention solves the technological scheme that its technical problem adopts and comprises the chain pulley seat that is provided with center hole, be provided with keyway in the center hole of chain pulley seat, chain pulley seat is provided with the sprocket wheel fixed hole, described chain pulley seat is provided with the protruding rank that are connected as a single entity, be fixed with the wheel body that is made of two fan-shaped wheel bodys at least on the protruding rank, the cylindrical of fan-shaped wheel body is provided with external tooth.
Connect by the negative and positive draw-in groove between the described fan-shaped wheel body.
After adopting said structure, the wheel body that fan-shaped wheel body is formed more than two or two directly is fixed on the protruding rank of chain pulley seat, connect by the negative and positive draw-in groove between the fan-shaped wheel body, be connected and fixed reliable, when the sprocket wheel wearing and tearing need be changed, only need change fan-shaped wheel body and get final product, need not to dismantle wheel and rear wheel seat, dismantle and change conveniently, solved the repairing difficulty that the sprocket wheel wearing and tearing bring; Have simple in structure, repair characteristics such as convenience, cost province.
Four, description of drawings
Fig. 1 is the invention left view.
Fig. 2 is the A-A sectional structure schematic representation of Fig. 1
Five, embodiment
Illustrated in figures 1 and 2, specific embodiments for the invention disassembly-type sprocket wheel, it comprises the chain pulley seat 2 that is provided with center hole, be provided with keyway 5 in the center hole of chain pulley seat 2, chain pulley seat 2 is provided with sprocket wheel fixed hole 1, and described chain pulley seat 2 is provided with the protruding rank 4 that are connected as a single entity, fix the wheel body that constitutes by two fan-shaped wheel bodys 3,6 by screw on the protruding rank 4, the cylindrical of fan-shaped wheel body 3,6 is provided with external tooth, connects by negative and positive draw-in groove 8 between the fan-shaped wheel body 3,6, also can connect with slot.Certainly, wheel body also can be made up of the fan-shaped wheel body 3 more than two, can reach the purpose of the invention equally.
