Described pull bar is thread section away from an end of Tensioner frame, is bolted with two nuts of tightening in opposite directions on this thread section and consists of described bounding means.
Belt transmission buffer memory expansion tightening wheel device of the present utility model, during assembling, slow fastening nut, make nut prop up guide sleeve and pull pull bar to the side shifting away from Tensioner frame, the stage clip that is set with on pull bar is gradually reduced, in this process, tensioner belt pulley and Tensioner frame clockwise rotate around the articulating point of Tensioner frame and support, pull bar and stage clip rotate counterclockwise around the articulating point of pull bar and Tensioner frame, guide sleeve is fixed on support, and pull bar produces certain skew with rotating in the via hole of guide sleeve.Stage clip is compressed to certain position, with belt sleeve on the tensioner belt pulley, slowly unscrew nut, stage clip after compression utilizes the elastic tensioning belt of self, until the elastic force of stage clip after compression and the pulling force of belt reach state of equilibrium, the stage clip after compression utilizes the elasticity that the elasticity of self can the buffer memory belt.In use, in the situation that in belt transmission beat or use a period of time after elongate, the decrement automatic makeup that belt tightening wheel utilizes stage clip to, tensioner belt pulley and Tensioner frame rotate counterclockwise around the articulating point of Tensioner frame and support, pull bar and stage clip clockwise rotate around the articulating point of pull bar and Tensioner frame, are able to tensioner belt constantly.
A kind of belt transmission buffer memory expansion tightening wheel device, comprise the tensioner belt pulley, also comprise the support and the Tensioner frame that are hinged, described tensioner belt pulley rotates the other end of being located at Tensioner frame, and the hinge axes of the rotation axis of tensioner belt pulley and support and Tensioner frame be arranged in parallel; The hinged pull bar that is provided with on described Tensioner frame, the guide sleeve sleeve that the other end of this pull bar and is rotatably connected on described support coordinates, and has the through hole that inserts for pull bar on this guide sleeve; Be set with stage clip on described pull bar, this stage clip one end is resisted against Tensioner frame, and the other end is resisted against described guide sleeve, and described pull bar is provided with bounding means away from an end of Tensioner frame.
Described pull bar is thread section away from an end of Tensioner frame, is bolted with two nuts of tightening in opposite directions on this thread section and consists of described bounding means.
Belt transmission buffer memory expansion tightening wheel device of the present utility model, guide sleeve is rotatably connected on support, and pull bar passes the through hole of guide sleeve.In using process, guide sleeve can rotate along with the skew of pull bar, makes pull bar and guide sleeve plane maintenance plumbness, increases the displacement amount of pull bar, and then increases the automatic tension scope of tensioner belt pulley, and is easy to use.
Belt transmission buffer memory expansion tightening wheel device of the present utility model, utilize pull bar and stage clip to adjust the position of tensioner belt pulley, stage clip after compression with the elasticity of self can the buffer memory belt elasticity, in the situation that in belt transmission beat or use a period of time after elongate, the decrement automatic makeup that belt tightening wheel can utilize stage clip to, be able to tensioner belt constantly; Come the tensioner belt with belt transmission buffer memory expansion tightening wheel device, avoid belt to jump out outside the tensioner race, also needn't be often tensioner belt pulley again, extend working life of belt.
