The device adopts the coupler and the bearing to ensure that the transmission shaft only transmits rotating torque and avoids vibration generated under the influence of centrifugal eccentric force, and the synchronous pulley device is high in axiality, good in output synchronism, high in transmission accuracy, simple in structure, convenient to assemble and low in cost, prolongs the service life of machinery, and meets the needs of industrial production.
Description
Technical field
The utility model relates to the machinery field, relates in particular to a kind of synchronous pulley device.
Background technique
The transmission shaft mechanism of present many machinery equipments comprises transmission shaft, input belt wheel, output pulley, in the process of transmitting driving torque; Have following defective: 1. because the uneven centrifugal inertia force that produces of part makes transmission shaft produce bending and torsional deflection, drive line also can produce mechanical vibration under varying load; This will influence the working life and the performance of machinery; Can make part produce fatigue ruption, 2. can not guarantee the synchronism exported, transmission accuracy is lower.
Summary of the invention
For addressing the above problem, the utility model provide a kind of transmission accuracy high, simple in structure, eliminate transmission shaft bending and mechanical vibration, the prolonged mechanical synchronous pulley device in working life.
The technological scheme of the utility model is achieved in that a kind of synchronous pulley device; It is characterized in that: comprise transmission shaft, duplex chain wheel, coupling, synchronous pulley, synchronous pulley fixed base, bearing, bearing support, connection square tube; The transmission shaft middle part is provided with the duplex chain wheel that is connected with exterior motor and is connected with transmission shaft through key; The duplex chain wheel both sides respectively are equipped with a pair of coupling; Coupling is fixedly connected through the coupling bearing pin, two bearings of mirror image each other about each coupling both sides is equipped with, and each coupling respectively is provided with a synchronous pulley away from the outside of duplex chain wheel direction and is connected with transmission shaft through spline; Two bearings of symmetry are installed in each synchronous pulley and pass through the bearing support location; The bearing support arranged outside has the synchronous pulley fixed base, and the synchronous pulley fixed base is fixedly connected with being connected square tube, and the two ends spindle nose of transmission shaft is respectively equipped with bearing.
Synchronous pulley links to each other with the external moving platform through tooth bar.
The beneficial effect of the utility model is: this device has guaranteed that through the structure that adopts coupling and bearing transmission shaft only transmits driving torque and do not receive the influence of centrifugal eccentric force to produce vibration, and coaxality is high, and the output synchronism is good; Transmission accuracy is high; Prolonged mechanical service life, and simple in structure, easy to assembly; Cost is low, adapts to the commercial production needs.

Embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed explanation.
Embodiment 1; A kind of synchronous pulley device; With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5; It is characterized in that: comprise transmission shaft 1, duplex chain wheel 2, coupling 3, synchronous pulley 8, synchronous pulley fixed base 9, bearing 6, bearing support 7, connect square tube 10, transmission shaft 1 middle part is provided with the duplex chain wheel 2 that is connected with exterior motor and is connected with transmission shaft 1 through key, and duplex chain wheel 2 both sides respectively are equipped with a pair of coupling 3; Coupling 3 is fixedly connected through coupling bearing pin 4; Coupling bearing pin 4 arranged outside have coupling bearing pin baffle plate 5, two bearings 6 of mirror image each other about each coupling 3 both sides is equipped with, and each coupling 3 respectively is provided with a synchronous pulley 8 away from the outside of duplex chain wheel 2 directions and is connected with transmission shaft 1 through spline; Two bearings 6 of symmetry are installed in each synchronous pulley 8 and pass through bearing support 7 location; Bearing support 7 arranged outside have synchronous pulley fixed base 9, and synchronous pulley fixed base 9 is fixedly connected with being connected square tube 10, and the two ends spindle nose of transmission shaft 1 is respectively equipped with bearing 6.
Synchronous pulley 8 links to each other with the external moving platform through rubber tape.
Connect square tube 10 and link to each other, location synchronous pulley fixed base 9 with outside support.
More than constituted a kind of structure of the utility model.
The utility model is such installment work: the transmission shaft 1 two ends coaxality after at first each part connects, installs is regulated and is finished; Motor is imported driving torque through duplex chain wheel 2 to device then; The synchronous pulley 8 of duplex chain wheel 2 drive both sides does to rotate synchronously output, and synchronous pulley 8 drives the motion of external moving platform through rubber tape.For adapting to bigger transmission of torque, synchronous pulley 8 adopts spline to be connected with transmission shaft 1, and for preventing the wearing and tearing of spline, synchronous pulley 8 set inside have bearing 6, also are provided with many places bearing 6 on the transmission shaft 1, prevent the radial deflection of axle, alleviate mechanical vibration.
The embodiment of the above is the preferred embodiment of the utility model only, is not the practical range that limits the utility model with this, so the equivalence that the shape of all the utility model, structure and principle are done changes, all should be covered by in the protection domain of the utility model.
