Abstract
The invention provides a kind of improved type double-chain automatic regulation tensioning mechanism, the synchronism of its two chain is good, can not produce to take off chain, sideslip, and its wearing and tearing are little, and then reduces breakdown rate, service expenditure.The chain that it comprises two synchronized operations is characterized in that: in described two chains, a chain engages is in the outside of profile of tooth tension wheel, and another root chain is set in the chain mounting groove of described track adjusting wheel.
Description
(1) technical field
The present invention relates to the material handling machinery field of mechanical engineering, be specially a kind of improved type double-chain automatic regulation tensioning mechanism.
(2) background technology
Double-stranded stretching device is to be used for all kinds of large-scale load transfer devices adjusting chains to loosen, tighten next common structure form.Existing double-stranded stretching device is a bidentate shape stretching device, its tooth Profile Machining requires high, poor synchronization, chain two chains in service serious climbing tooth phenomenon can occur when asynchronous extension occurring, phenomenons such as chain, sideslip, wearing and tearing increasing are taken off in generation, make fault rate, the service expenditure height of equipment and whole dust-removal system.
(3) summary of the invention
At the problems referred to above, the invention provides a kind of improved type double-chain automatic regulation tensioning mechanism, the synchronism of its two chain is good, can not produce to take off chain, sideslip, and its wearing and tearing are little, and then reduce breakdown rate, service expenditure.
Its technical scheme is such: the chain that it comprises two synchronized operations is characterized in that: in described two chains, a chain engages is in the outside of profile of tooth tension wheel, and another root chain is set in the chain mounting groove of described track adjusting wheel.
It is further characterized in that: the tooth of the circumferential end of described profile of tooth tension wheel is a heteromorphic teeth; Described track adjusting wheel is a halo, and described profile of tooth tension wheel, track adjusting wheel connect by adapter shaft, and described adapter shaft two axial ends is passed through bearing, bearing block support respectively in support.
In the said structure of the present invention, because described two chains connect profile of tooth tension wheel, track adjusting wheel respectively, a described chain engages connects described profile of tooth tension wheel, another root chain connects described track adjusting wheel by the chain mounting groove, described profile of tooth tension wheel can prevent the chain sideslip, described track adjusting wheel is because it connects described another root chain by described smooth chain mounting groove, it can compensate the elongation asynchronism that chain occurs, so the synchronism of its two chain is good, can not produce and take off chain, sideslip, its wearing and tearing are little, and then reduce breakdown rate, service expenditure.
(4) description of drawings
Fig. 1 is a front view scheme drawing of the present invention.
(5) specific embodiment
See Fig. 1, the present invention includes the chain (for existing mature technology, not drawing among the figure) of two synchronized operations, a chain engages is in the outside of profile of tooth tension wheel 1, and another root chain is set in the chain mounting groove 3 of track adjusting wheel 2.The tooth of the circumferential end of profile of tooth tension wheel 1 is a heteromorphic teeth, and track adjusting wheel 2 is a halo, and profile of tooth tension wheel 1, track adjusting wheel 2 connect by adapter shaft 4, and adapter shaft 4 two axial ends are supported on support (prior art is not drawn among the figure) by bearing 5, bearing seat 6 respectively.
Claims (4)
1, a kind of improved type double-chain automatic regulation tensioning mechanism, the chain that it comprises two synchronized operations is characterized in that: in described two chains, a chain engages is in the outside of profile of tooth tension wheel, and another root chain is set in the chain mounting groove of described track adjusting wheel.
2, according to the described a kind of improved type double-chain automatic regulation tensioning mechanism of claim 1, it is characterized in that: the tooth of the circumferential end of described profile of tooth tension wheel is a heteromorphic teeth.
3, according to the described a kind of improved type double-chain automatic regulation tensioning mechanism of claim 2, it is characterized in that: described track adjusting wheel is a halo.
4, according to the described a kind of improved type double-chain automatic regulation tensioning mechanism of claim 3, it is characterized in that: described profile of tooth tension wheel, track adjusting wheel connect by adapter shaft, and described adapter shaft two axial ends is passed through bearing, bearing block support respectively in support.
