A kind of conveyor chain tightening device
Technical field
The present invention relates to technical field of conveying machinery, especially a kind of conveyor chain tightening device.
Background technology
Tension wheel is a kind of device for Chain conveyer tensioning, when the width between centers of conveyer chain can not regulate, tension wheel can be adopted band tensioning to be prevented from engaging vibration that is bad and chain.The Large-scale machine set that tension wheel uses in manufacturing all has application, and tension wheel can regulate the degree of tightness of conveyer chain.But unit is in using for a long time, and due to reasons such as tension wheel generation is loosening, wearing and tearing, discontinuity can occur in rotation process, and traditional tightening device not easily regulates, and tension wheel conveyer chain fluffs or deflection, thus makes transmission occur deviation.
Summary of the invention
The present invention will solve the shortcoming of above-mentioned prior art, provides a kind of conveyor chain tightening device, is a kind ofly to carry out position adjustments, fixing and can prevent tension wheel unbalance stress and tension pulley support of offseting in operational process to tension wheel at any time.
The present invention solves the technical scheme that its technical matters adopts: this conveyor chain tightening device, mainly comprise adapter plate, tensioning support, tensioning screw, fastening block, nut, minor axis and sprocket wheel, described adapter plate and fastening block are for maintaining static structure, and adapter plate is provided with row's constant worm pich hole; Described tensioning support is made up of one piece of base plate, two pieces of side plates and two pieces of baffle plates, and in inverted trapezoidal pattern, below is circular arc; The base plate of described tensioning support has 2 slippage slots, the constant worm pich hole of adapter plate and the slippage slot of tensioning support are on same line of centers, in sliding connection between adapter plate and tensioning support, tensioning support centrally can carry out linear slide by line on a mounting board; The baffle plate at described tensioning support two is provided with the tapped bore coordinated with tensioning screw, and tensioning screw is through fastening block and baffle plate, and respectively there is 1 nut described fastening block both sides, and tensioning screw is fixed on fastening block by two nuts; The side plate of described tensioning support is provided with the circular hole for fixing minor axis, and sprocket wheel is connected with tensioning support by minor axis; Described tensioning support, minor axis and sprocket wheel are undertaken regulating and being fixed by bolt by tensioning screw and nut relative to the position of adapter plate, realize the tensioning of conveyor chain or loosen.
The length of described slippage slot is greater than the spacing in constant worm pich hole, and described tensioning support is by being installed on being bolted on adapter plate in constant worm pich hole.
The effect that the present invention is useful is: utilize conveyor chain tightening device provided by the invention can keep suitable chain tension and avoid chain to shake, and easy to adjust, fixing reliable, ensure that the Stability and veracity that transport plane operates.
