Description
Technical field
The utility model relates to a kind of orbital transmission of spinning machinery, relates in particular to a kind of thickness connection orbital transmission.
Background technology
Thickness connection is exactly the rove automatic conveying system connecting between Speed frames and fine spining machine in brief.Thickness connection makes Speed frames and fine spining machine form an automation spinning unit.Fig. 1 is thickness connection orbital transmission mounting structure schematic diagram, and Fig. 2 is thickness connection orbital transmission operation principle schematic diagram.As shown in Figure 1 and Figure 2, on the track of thickness connection, have chain, chain is for delivery of spool and realize the automatic exchange that thickness joins sky, full spool.On track, be all separately installed with at a certain distance paired driving wheel 2 and the follower 5 of chain drive-belt motion, each driving wheel 2 is all equipped with independently the motor 1 with reductor to drive.Each paired driving wheel 2 and follower 5 be take chain 4 and are arranged on the both sides of chain 4 as symmetry axis symmetry, and chain 4 is along the side that is fitted in guide rail 3.Between above-mentioned paired driving wheel 2 and follower 5 and chain 4, it is compression fit, while driving driving wheel 2 to rotate clockwise with the motor 1 of reductor, driving wheel 2 drives chain 4 to travel forward from left to right, and chain 4 provides frictional force to drive follower 5 to rotate in the counterclockwise direction.
Now in conjunction with Fig. 1, Fig. 2 describes the operation principle of thickness connection orbital transmission, as Fig. 1, shown in Fig. 2, the motion of chain adopts the mode transmitting step by step, (for convenience of description, direction with the arrow indication of the chain moving direction described in Fig. 2 is divided into driving wheel the first driving wheel successively, certain of the second driving wheel) take on chain is some initiating terminal, suppose that this initiating terminal is positioned at and the first driving wheel contact position at present, when the first driving wheel drives chain that chain is travelled forward by frictional force, after the initiating terminal of chain moves forward to and contacts with the second driving wheel, the transmission work of previous stage completes, the motor of first driving wheel of this grade shuts down, the transmission work of next stage starts simultaneously, the motor entry into service of the second driving wheel, by the second driving wheel, continuing chain drive-belt travels forward, be similar to the handing-over successively of the front and back relay baton in relay pace, the above-mentioned course of work repeats step by step until the end of machine.
On guide rail, be provided with some groups by the motor-driven driving wheel with reductor, each driving wheel is supporting corresponding follower, each driving wheel and and the supporting follower of driving wheel between be chain, above-mentioned driving wheel, follower become compression fit with chain respectively, when electric motor starting with reductor, driving wheel rotates clockwise, and follower is for counterclockwise rotation, and the acting in conjunction of chain frictional force respectively and between driving wheel and follower by it travels forward.
Certain of take on chain is some initiating terminal, when this initiating terminal is between the first driving wheel and the first driving wheel, the first electric motor starting with reductor while driving the first driving wheel to start to rotate clockwise, now the first follower is for counterclockwise rotation, and the first driving wheel orders about chain and travels forward;
When chain moves a segment distance, when the initiating terminal of above-mentioned chain arrives the position between the second driving wheel and the second follower, first closes with the motor of reductor, second opens with the motor of reductor simultaneously, when the second motor with reductor drives the second driving wheel to rotate clockwise, the second follower is for counterclockwise rotation, and the second driving wheel chain drive-belt moves forward.Now, because the first motor with reductor shuts down, this first driving wheel just can initiatively not provide driving force to chain again, that is to say, this first driving wheel no longer provides positive direction power to chain, on the contrary, the frictional force of chain respectively and between the first driving wheel and the first follower becomes the proal resistance of chain.
Fig. 3 is the driving wheel cross-sectional view along transverse cross sectional of prior art; Fig. 4 is the driving wheel cross-sectional view of longitudinally dissecing of prior art.
As shown in Figure 3 and Figure 4, of the prior art is integral type structure by the motor-driven driving wheel 2 with reductor, and wherein, the outer circumference surface of driving wheel has line with rubber layer 19.
Fig. 5 is the thickness connection orbital transmission mounting structure schematic diagram of prior art, and driving wheel 2 is fixedly connected with the motor 1 with reductor as shown in the figure, and the both sides of chain 4 are respectively driving wheel 2 and follower 5, and chain is fitted in the side of guide rail 3.
In conjunction with Fig. 1-5, orbital transmission operation principle to thickness connection is analyzed, can find out, because the first driving wheel is directly rigidly connected with the first motor shaft with reductor, under normal circumstances, frictional force between chain and the first driving wheel can not drag the first driving wheel and continue to clockwise rotate, and can only drag the first follower, continues to do anticlockwise rotation.That is, now the first driving wheel is inactive state, and the first follower is rotated further.Now, the frictional force between chain and the first driving wheel is stiction, and the frictional force between chain and the first follower is force of rolling friction.
Force analysis situation from the thickness connection track main drive course of work of above-mentioned prior art can find out that in its structure, defect is brought obvious technical problem, mainly contains the following aspects:
1, chain in use continues to be subject to the stretching of larger power, easily causes chain elongated, affects stability and the security of whole equipment operation, and then affects the stable of quality and improve, and causes larger economic loss.
2, be integral type structure with the rigidly connected driving wheel of motor with reductor, after causing motor to stop, the driving wheel and the frictional force between chain that being connected with this motor are transformed into by force of rolling friction the stiction that strength strengthens greatly.
3, the reason based on described in above-mentioned the 2nd, the wearing and tearing of chain and driving wheel are large, cause its maintenance and repair cycle to shorten; And because driving wheel is steel lining plastic structure, its unit price is higher, so the maintain and repair methods expense of whole thickness connection equipment is huge.
4, chain is in use long-term stressed larger, easily causes fatigue damage, and then has increased the probability that equipment parking accident occurs.
5, the frictional force between chain and driving wheel is transformed into after the stiction that strength strengthens greatly by force of rolling friction, causes the increase of next stage motor load, thereby causes the increasing of meaningless consume of the energy.
