Description
Technical field
The utility model relates to a kind of fixed drive sprockets, belong to mechanical drive chain wheel technical field.
Background technique
Sprocket wheel is the wheel with cog type whelp, to be meshed with the accurate block of pitch on pitch chain ring or cable,
Sprocket wheel is one of component crucial in mechanical driving, and traditional sprocket wheel is to connect by inner hole with axle key, is used for a long time
It will lead to bore wear, influence working efficiency, and axis is connected by key when imparting power to sprocket wheel, the active force of axis rotation
It all concentrates on key, causes the endurance of key big, the interaction force between axis and sprocket wheel is uneven.
Summary of the invention
To solve the deficiencies in the prior art, the utility model provides a kind of fixed drive sprocket, change traditional sprocket wheel with
The transmission connection mode of axis, effectively increases the inner hole of sprocket wheel and the contact surface of axis, and the active force for rotating axis uniformly transfers
To sprocket wheel, transmission efficiency is effectively improved, extends the service life of sprocket wheel, guarantees the stability of sprocket wheel at work.
Technical solution used by the utility model is：
A kind of fixed drive sprocket, including symmetrically arranged two wheel bodys, the periphery of the wheel body are formed with the gear teeth, institute
It states and is formed with inner hole in the middle part of wheel body, be formed on the inner sidewall of the inner hole around one week tooth connection of inner hole inner sidewall,
Tooth connection on two wheel bodys corresponds to each other, and is also evenly arranged with several key connection holes on the wheel body, on two wheel bodys
It is keyed hole to correspond to each other, and two wheel bodys are connected by key axis insert key connecting hole.
As the further preferred of the utility model, there are six the key connection hole settings on the wheel body, improves two wheels
The connective stability of body.
As the further preferred of the utility model, the width of the gear teeth is the half for taking turns body thickness.
As the further preferred of the utility model, the width of the tooth connection is the half for taking turns body thickness.
As the further preferred of the utility model, the gear teeth and tooth connection be not in same plane.
As the further preferred of the utility model, the key axis and key connection hole interference fit are connected, and make two wheels
Body is closely joined together.
The beneficial effects of the utility model are：For sprocket wheel using two Wheel structures to link together, two wheels are internal
Mutual corresponding tooth connection changes the transmission connection side of traditional sprocket wheel and axis for being connected by meshing transmission with the gear on axis in hole
Formula effectively increases the inner hole of sprocket wheel and the contact surface of axis, and the active force for rotating axis is uniformly transferred to sprocket wheel, effectively improves
Transmission efficiency extends the service life of sprocket wheel, guarantees the stability of sprocket wheel at work.
Detailed description of the invention
Fig. 1 is the positive structure schematic of the utility model；
Fig. 2 is the side structure schematic diagram of the utility model；
Fig. 3 is A in Fig. 2 to schematic cross-sectional view；
Main appended drawing reference meaning is as follows in figure：
1- wheel body, the 2- gear teeth, 3- inner hole, 4- tooth connection, 5- are keyed hole.
Specific embodiment
Specific introduction is done to the utility model with reference to the accompanying drawings and examples.
As shown in Figs. 1-3：The present embodiment is a kind of fixed drive sprocket, including symmetrically arranged two wheel bodys 1, is being taken turns
The periphery of body 1 is formed with the gear teeth 2, is formed with inner hole 3 at the middle part of wheel body 1, is formed on the inner sidewall of inner hole 3 around inner hole
3 one week tooth connection of inner sidewall 4, the tooth connection 4 on two wheel bodys 1 correspond to each other, and are also evenly arranged with several keys on wheel body 1
Connecting hole 5, the key connection hole 5 on two wheel bodys 1 correspond to each other, and two wheel bodys 1 pass through the connection of key axis insert key connecting hole 5.
In the present embodiment, there are six the settings of key connection hole 5 on wheel body 1, improves the connective stability of two wheel bodys 1.
In the present embodiment, the width of the gear teeth 2 is the half of 1 thickness of wheel body.
In the present embodiment, the width of tooth connection 4 is the half of 1 thickness of wheel body.
In the present embodiment, the gear teeth 2 and tooth connection 4 be not in same plane.
In the present embodiment, key axis and key connection hole 5 interference fit are connected, and are closely joined together two wheel bodys 1.
When installation, by two wheel bodys 1 respectively from two end caps of axis on axis, and make to correspond to each other in two wheel bodys, 1 inner hole 3
Tooth connection 4 engaged with the gear on axis, then two wheel bodys 1 are linked together by key axis, the gear on axis with
Axis is integral structure.
The utility model sprocket wheel uses two Wheel structures to link together, mutual corresponding company in two wheel body inner holes
Tooth is connect for being connected by meshing transmission with the gear on axis, changes the transmission connection mode of traditional sprocket wheel and axis, effectively increases sprocket wheel
Inner hole and axis contact surface, the active force for rotating axis uniformly transfers to sprocket wheel, effectively improves transmission efficiency, extend chain
The service life of wheel guarantees the stability of sprocket wheel at work.
The above is only the preferred embodiment of the utility model patent, it is noted that for the general of the art
For logical technical staff, under the premise of not departing from the utility model patent principle, several improvements and modifications can also be made, this
A little improvements and modifications also should be regarded as the protection scope of the utility model patent.
