Abstract
The utility model discloses a kind of chain to automatically adjust tensioning apparatus, including：Crossbeam, it is rotatably connected on the U-typed connector and a pair of swing rods of crossbeam left and right ends, it is threaded in the guide rod of connector bottom, it is threaded in the nut at guide rod both ends, the sliding part being slidably connected on the guide bar, the spring of suit on the guide bar, the sprocket wheel being rotatably connected in the middle part of swing rod, the chain being sleeved on sprocket wheel.During work, tension force of spring can be such that sliding part slides on the guide bar, so as to be swung with driven fork so that sprocket wheel can move left and right, so as to realize the purpose of regulation tensioning.The utility model simple installation, it is not necessary to manual adjustment, automatically adjust chain tension, improve operating efficiency.
Description
Technical field
A kind of chain gear transmission technical field is the utility model is related to, more particularly to a kind of chain automatically adjusts tensioning apparatus.
Background technology
Chain gear transmission is to be widely used in a kind of machine driving of multiple industries, and it does not have Elastic Sliding and skidding, can be protected
Hold accurate average ratios, it is necessary to tensile force it is small.Sprocket transmission device inevitably will after a period of time is run
There is chain wear, so that chain link is elongated；If slack list chain can not be tensioned in time, it will cause and jump tooth or de- chain, cause
Sprocket transmission device failure increases, and influences production efficiency.In addition, current existing chain stretching device is mostly regulation manually
Tight chain, and tension chain can not be automatically adjusted, such device is wasted time and energy, cumbersome, has a strong impact on operating efficiency.
The content of the invention
In order to solve the above problems, the utility model provides a kind of chain and automatically adjusts tensioning apparatus, and the device need not
Manual adjustment, tension chain is automatically adjusted, improve operating efficiency.
To reach above-mentioned purpose, the utility model uses following technical scheme：
The utility model provides a kind of chain and automatically adjusts tensioning apparatus, including：Crossbeam, the left and right ends of the crossbeam are set
There is through hole；
The U-typed connector of crossbeam left end is rotatably connected on, the bottom of the connector is provided with through hole；
Be threaded in the guide rod of connector bottom, the both ends of the guide rod are provided with screw thread, the guide rod it is upper
End screw thread screws on the first nut after connector；
Sliding part, the middle part of the sliding part is square, and both ends are cylindric, and the middle part square department of the sliding part separates
There is through hole, the sliding part is slidably connected on the guide bar；
The spring of suit on the guide bar；
It is threaded in the second nut of guide rod lower end；
A pair of swing rods at sliding part both ends are sleeved on, the other end of the swing rod is rotatably connected on the right-hand member of crossbeam respectively
Front and rear sides；
The sprocket wheel being rotatably connected in the middle part of swing rod；
The chain being sleeved on sprocket wheel.
The rotation connection is bearing pin connection.
During work, tension force of spring can be such that sliding part slides on the guide bar, so as to be swung with driven fork so that sprocket wheel can
Move left and right, so as to realize the purpose of regulation tensioning.
The utility model simple installation, it is not necessary to manual adjustment, automatically adjust chain tension, improve operating efficiency.
Brief description of the drawings
Fig. 1 is main structure diagram of the present utility model.
Fig. 2 is part-structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with the accompanying drawings and the utility model is described in further detail, so that those skilled in the art can be more clear
The understanding of Chu.
A kind of chain of the utility model, which is can be seen that, from Fig. 1 and Fig. 2 automatically adjusts tensioning apparatus, including：Crossbeam 1, it is described
The left and right ends of crossbeam 1 are provided with through hole；
The U-typed connector 2 of the left end of crossbeam 1 is rotatably connected on, the bottom of the connector 2 is provided with through hole；
The guide rod 3 of the bottom of connector 2 is threaded in, the both ends of the guide rod 3 are provided with screw thread, the guide rod 3
Threaded upper ends the first nut 4 is screwed on after connector 2；
Sliding part 5, the middle part of the sliding part 5 is square, and both ends are cylindric, the middle part square department of the sliding part 5
Separately there is through hole, the sliding part 5 is slidably connected on guide rod 3；
The spring 6 being sleeved on guide rod 3；
It is threaded in the second nut 7 of the lower end of guide rod 3；
A pair of swing rods 8 at the both ends of sliding part 5 are sleeved on, the other end of the swing rod 8 is rotatably connected on the right side of crossbeam 1 respectively
The front and rear sides at end；
It is rotatably connected on the sprocket wheel 9 at the middle part of swing rod 8；
The chain 10 being sleeved on sprocket wheel 9.
The rotation connection is bearing pin connection.
During work, the tension force of spring 6 can be such that sliding part 5 is slided on guide rod 3, so as to be swung with driven fork 8 so that chain
Wheel 9 can move left and right, so as to realize the purpose of regulation tensioning.
The utility model simple installation, it is not necessary to manual adjustment, automatically adjust chain tension, solve due to chain pine
The dynamic maintenance problem brought, improves operating efficiency.
