For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of sprocket tension device.
The utility model solves the technological scheme that its technical problem adopts: described a kind of sprocket tension device, this tension device comprises: frame, be arranged at the tension sprocket in frame, frame below described tension sprocket is provided with determines sprocket wheel, described frame is provided with adjustment screw, threaded pipe is combined with in described adjustment screw, described threaded pipe one end is closed, described threaded pipe is closed one end and is provided with guiding unthreaded hole, guide pillar is combined with in described guiding unthreaded hole, tension spring is provided with in described threaded pipe, described tension spring is enclosed within described guide pillar, described frame is provided with chute, described chute is without determining sprocket wheel axle center, tensioning slide block is combined with in described chute, described tension sprocket is arranged on tensioning slide block, described tension sprocket and describedly determine sprocket wheel is wound with chain, described chain is S-shaped around described tension sprocket with describedly determine on sprocket wheel, described tension spring one end is connected with tensioning slide block, the described tension spring the other end is connected with threaded pipe closed end, described tension spring is consistent with track length direction to the force direction of tensioning slide block.
Tension spring is utilized directly to contact with tensioning slide block in above-mentioned design, tensioning fast response time; Directly regulate the tension force of tension spring by means of only threaded pipe, its structure is simple, component long service life.
As the better improvement of the design, described tension sprocket and determine sprocket wheel and be two and be symmetrical set in frame.Described tension sprocket and determine sprocket wheel and be two speed of response can be made faster.
As the better improvement of the design, described chute is horizontal slot, and described chute is one, and namely described tensioning slide block slides in a chute.A chute reduces difficulty of processing, cost-saving.
As the better improvement of the design, described threaded pipe upper outer surface has also been threaded nut, and described nut and described threaded pipe closed end are fitted.Described nut prevents threaded pipe vibration from getting loose, and improves the reliability of equipment.
The beneficial effects of the utility model are: the utility model utilizes tension spring directly to contact with tensioning slide block, tensioning fast response time; Directly regulate the tension force of tension spring by means of only threaded pipe, its structure is simple, component long service life.
