Description
Technical field
The utility model relates to a kind of automatic synchronization structures of chain drive.
Background technique
Chain conveyer is to engage the kind of drive for realizing power transmitting with drive sprocket and driven sprocket by chain, no bullet
Property sliding and slipping phenomenon, average ratios it is accurate, reliable operation is high-efficient, transmitting power it is big, overload capacity is strong, answers extensively
Power transmission for mechanical equipment.Chain conveyer is equipped at intervals with drive shaft and driven shaft, drive shaft on the rack in practical application
It is respectively equipped with drive sprocket and driven sprocket with the both ends of driven shaft, drive shaft is driven by decelerating motor, chain and drive chain
Wheel and driven sprocket engagement, to realize power transmission.In the drive mechanism, chain is be easy to cause to jump tooth, take off the problems such as tooth,
It will lead to chain breakage, sprocket wheel damage under serious conditions, therefore need to adjust sprocket wheel spacing by constantly debugging, merging, reach
The synchronous operation of chain.But, debugging cost height higher for the skill requirement of commissioning staff is debugged, and the processing of components is wanted
Ask also high, debug time is long, and stability is poor, seriously affects chaindriven normal, reliability service.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of automatic synchronization structure of chain drive, this structures gram
The defect that chain in chain conveyer easily jumps tooth, de- tooth is taken, the automatic synchronization operation of chain is realized, improves the stability of transmission, reduce
Production run cost, it is ensured that chaindriven normal, reliability service.
In order to solve the above technical problems, the automatic synchronization structure of the utility model chain drive include rack, drive shaft, from
Moving axis, drive sprocket, driven sprocket, chain and decelerating motor, the drive shaft and driven shaft are set to institute by bearing block interval
It states in rack, the drive sprocket is set to the drive shaft both ends by key and keyway, and the decelerating motor is set to the rack
Side simultaneously connects described drive shaft one end, this structure further includes strainer and zanjon bearing, and described driven shaft one end passes through key
A driven sprocket, the other end are equipped with keyway, and another driven sprocket, the drive shaft and driven are equipped with by the zanjon bearing
The drive sprocket at axis both ends and the position of driven sprocket are corresponding, and the chain is around the drive sprocket and driven sprocket and nibbles
It closes, the strainer is set to the rack two sides and is tensioned the chain.
Further, the decelerating motor is coupled using hollow shaft form with the drive shaft.
Since the automatic synchronization structure of the utility model chain drive uses above-mentioned technical proposal, the i.e. driving of this structure
Axis and driven shaft are set in rack by bearing block interval, and drive sprocket is set to drive shaft both ends by key and keyway, and slow down electricity
Machine is set to rack side and connects drive shaft one end, and driven shaft one end is equipped with a driven sprocket by key and keyway, the other end leads to
Zanjon bearing is crossed equipped with another driven sprocket, the position of the drive sprocket and driven sprocket at drive shaft and driven shaft both ends is corresponding,
Chain is around drive sprocket and driven sprocket and engages, and strainer is set to rack two sides and tension chain.This structure overcomes
Chain easily jumps the defect of tooth, de- tooth in chain conveyer, realizes the automatic synchronization operation of chain, improves the stability of transmission, reduce life
Produce operating cost, it is ensured that chaindriven normal, reliability service.
Detailed description of the invention
The utility model is described in further detail with embodiment with reference to the accompanying drawing:
Fig. 1 is the automatic synchronization structural schematic diagram of the utility model chain drive；
Fig. 2 be this structure in chain around with drive sprocket and driven sprocket connection schematic diagram.
Specific embodiment
Embodiment is as depicted in figs. 1 and 2, and the automatic synchronization structure of the utility model chain drive includes rack 1, drive shaft
2, driven shaft 3, drive sprocket 4, driven sprocket 5, chain and decelerating motor 7, the drive shaft 2 and driven shaft 3 pass through bearing block
21,31 intervals are set in the rack 1, and the drive sprocket 4 is set to 2 both ends of drive shaft by key and keyway, described to subtract
Speed motor 7 is set to 1 side of rack and connects described 2 one end of drive shaft, this structure further includes strainer 8 and zanjon bearing
9, described 3 one end of driven shaft is equipped with a driven sprocket 5, the other end by the zanjon bearing 9 equipped with another by key and keyway
Driven sprocket 5, the drive sprocket 4 at 3 both ends of the drive shaft 2 and driven shaft and the position of driven sprocket 5 are corresponding, the chain 6
It around the drive sprocket 4 and driven sprocket 5 and engages, the strainer 8 is set to described in 1 two sides of rack and tensioning
Chain 6.
Preferably, the decelerating motor 7 is coupled using hollow shaft form with the drive shaft 2.
Drive sprocket and drive shaft in this structure, between a driven sprocket and driven shaft even by the hardness of keyway and key
It connects, therefore between drive sprocket and drive shaft, the transmission between a driven sprocket and driven shaft is the state of moving synchronously.And it is another
It is connected between one driven sprocket and driven shaft by deep groove ball bearing, belongs to flexible connection, another driven sprocket and driven shaft
Between asynchronous movement can be achieved.
After the chain of rack two sides is separately connected drive sprocket and driven sprocket, by strainer tension chain, subtract
Speed motor drives drive shaft to drive drive sprocket rotation, and drive sprocket is rotated synchronously by chain-driving driven sprocket；Period by
In another driven sprocket and driven shaft be active connection, can adjust automatically rack two sides chain operate synchronously, avoid chain
The generation jumped tooth, beat phenomena such as tooth and de- tooth.
This structure is simple by debugging, only need to be by strainer tension chain, after the chain tension of two sides, the center of sprocket wheel
It is not more than 5mm away from difference, chain can all run well, and will not generate and jump tooth, beat the problems such as tooth and de- tooth.It is simple due to debugging, it is right
The skill requirement of commissioning staff is low, greatly reduces cost, and the stability debugged is good, will not be debugged and be generated by different personnel
Different debugging results.
