Abstract
The invention discloses a roll shaft transmission device with adjustable tension. The roll shaft transmission device is characterized in that a roller shaft is meshed with a transmission chain; the external side far away from the roll shaft, of the transmission shaft is provided with a tensioning wheel; the tensioning wheel is meshed with the transmission chain; the roll shaft is connected to the rack; and the tensioning wheel is connected to the rack. The roller shaft transmission device can adjust the tension of the transmission chain; the structure is simple; the operation is convenient; and the working state is stable.
Description
Technical field
The present invention relates to a kind of driving device, the slack-free roll shaft driving device of particularly a kind of scalable.
Background technology
The roll shaft driving device is widely used in activity in production, is mainly used in object and carries.
Traditional roll shaft driving device does not have the slack-free function of adjusting, in use, relaxing can appear in the messenger chain of roll shaft driving device, influence the stable operation of roll shaft driving device, tightening device of the prior art is aimed at conveyor belt design mostly, and existing tensioning device structure mainly is that applied spring, piston, adjusting bolt etc. are finished tensioning work, and complex structure is not suitable for and uses the roll shaft driving device of messenger chain as trailer coupling.
Summary of the invention
Technical matters to be solved by this invention is to overcome the deficiencies in the prior art, provides that a kind of can to regulate messenger chain slack-free, simple in structure, easy to operate, the roll shaft driving device of stable working state.
For solving the problems of the technologies described above, the invention provides the slack-free roll shaft driving device of a kind of scalable, roll shaft, frame and messenger chain, described roll shaft and messenger chain are connected with a joggle, and it is characterized in that, described roll shaft and messenger chain engagement, described messenger chain is provided with tension wheel away from the outside of roll shaft, described tension wheel and messenger chain engagement, described roll shaft is connected with frame, and described tension wheel is connected with frame.By tension wheel the tensioning of messenger chain is controlled, simple in structure, tension effects is good, does not influence the normal operation of roll shaft driving device.
Described tension wheel has two or more.Tension wheel can be arranged at a plurality of tension positions of roll shaft driving device easily, makes the running of roll shaft driving device more stable.
Described frame is provided with slideway, and described tension wheel is located on the slideway.By the adjusting of tension wheel on slideway, can control the slack-free dynamics of messenger chain, to reach better more stable tension effects.
The beneficial effect that the present invention reached is:
The tensioning state of dancer rools shaft drive messenger chain is simple in structure and easy to operate arbitrarily, good stability.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
The present invention is further illustrated below in conjunction with accompanying drawing.
As shown in Figure 1, roll shaft 1 two ends are connected with frame 2, the messenger chain 3 of roll shaft 1 both sides is enclosed within the two ends of roll shaft 1 respectively, connection is meshing with each other, one-sided messenger chain 3 is provided with the tension wheel 4 of two diverse locations away from the outside of roll shaft 1, tension wheel 4 is connected with a joggle with messenger chain 3, frame 2 is provided with slideway, tension wheel 4 is arranged on the slideway, can move back and forth along slideway, regulates the tensioning degree of tension wheel 4, if tensioning degree deficiency, then tension wheel 4 is slided to the direction near roll shaft 1, improve tensioning degree, otherwise then tension wheel 4 is slided to the direction away from roll shaft 1, reduce tensioning degree, as required, the tension wheel 4 of diverse location can its tensioning degree of free adjustment, to satisfy the needs in the actual use of roll shaft driving device.
The present invention is mainly used in stable transmission object, can regulate the messenger chain tensioning degree, and is simple in structure, easy to operate, stable working state.
Above embodiment limits the present invention never in any form, and every other improvement and application that above embodiment is made in the equivalent transformation mode all belongs to protection scope of the present invention.
