The invention discloses a belt tensioning device which comprises a basic part, a positioning shaft, an external hexagonal nut, an upper bearing, a lower bearing, a gland, a nail, a locking and positioning nail and a tensioning wheel. The gland is fixedly arranged on the basic part through the nail, the external hexagonal nut is arranged between the gland and the basic part, an upper end of the external hexagonal nut is connected with the gland through the upper bearing, a lower end of the external hexagonal nut is connected with the basic part through the lower bearing, the external hexagonal nut is matched with a thread arranged on the positioning shaft, the locking and positioning nail is arranged in a screw hole on the basic part and connected with the positioning shaft, and the tensioning wheel is arranged at a lower end of the positioning shaft. The belt tensioning device has the advantages of simple and exquisite structure, convenience in adjustment and manual operation, suitableness for V belt tensioning adjustment of ordinary occasions and easiness in workpiece processing and component assembly.
Description
technical field [0001] The invention relates to the field of mechanical equipment, in particular to a belt tensioner. Background technique [0002] The existing belt tensioning device generally adopts the worm gear tensioning structure, because the worm gear is difficult to process, and the material of the worm gear is expensive, the processing cycle is long, and the installation space is large, which virtually increases the cost. Contents of the invention [0003] In order to solve the above technical problems, the object of the present invention is to provide a tensioning device with simple and exquisite structure, convenient adjustment, convenient manual operation, suitable for V-belt tension adjustment in general occasions, and easy processing of workpieces and easy assembly of components. The specific plan is as follows: [0004] A belt tensioning device, comprising a base part, a positioning shaft, an outer hex nut, an upper bearing, a lower bearing, a gland, screws...
