Detailed Description
The utility model is shown in fig. 1-9, including belt pulley 1, extension board 2, end cover 3, center pin 4, spring 5 and spring support cover 6, belt pulley 1 articulates in one side of extension board 2, and the opposite side of extension board 2 is equipped with the connecting block 20 rather than being connected as an organic whole, spring support cover 6 cover is established outside connecting block 20, the storage tank has been seted up on the top surface of connecting block 20, the tank bottom of storage tank has seted up the holding hole, the lower part of center pin 4 passes the holding hole, and its bottom is fixed with spring support cover 6 and links to each other, end cover 3 fixed connection is at the top of center pin 4, and is in the notch of storage tank, spring 5 cup joints center pin 4, and the both ends of spring 5 support respectively on end cover 3 and connecting block 20;
the end face, back to the support plate, of the end cover 3 is provided with at least two torsion blind holes 31, and the end face, back to the support plate 2, of the spring support sleeve 6 is fixedly connected with at least one positioning bayonet pin 61;
a pair of limiting blocks 21 is fixedly connected to the side surface of the support plate 2, a limiting hook 62 is fixedly connected to the side surface of the spring support sleeve 6, and one end, far away from the spring support sleeve 6, of the limiting hook 62 is located between the pair of limiting blocks 21. Therefore, during assembly, the fixed connection between the central shaft and the spring support sleeve can be firstly completed, and then the support plate is placed, so that the connecting block is positioned in the spring support sleeve, and the top end of the limiting hook is positioned between the pair of limiting blocks; then, an operator can sequentially put the spring and the end cover, and the two ends of the spring are respectively lapped in the bottom surface of the end cover and the groove on the inner wall of the accommodating groove; finally, the fixed connection (usually riveting or welding) between the end cap and the central shaft is completed.
Before the fixed connection between the end cover and the central shaft is completed, an operator can pre-compress the spring according to the requirement of a customer on initial torsion, specifically: an operator can support the torsion blind hole and the positioning bayonet lock, and rotate the spring support sleeve or the end cover, firstly make the limit hook contact with one limit block, and then continue to rotate the spring support sleeve or the end cover, so that the support plate and the spring support sleeve synchronously rotate and relatively rotate with the end cover, and the spring is precompressed.
After the precompression is finished, an operator finishes the fixed connection between the end cover and the central shaft, namely the limiting hook can be abutted against one limiting block (the other limiting block can limit the stroke of the tensioner in the using process), and the spring keeps certain initial torsion so as to meet the requirements of customers.
The present case is through the structural design who twists reverse blind hole, location bayonet lock and spacing hook for the regulation of the initial torsion of spring is very convenient in the tensioning ware, thereby can be to different customers' demand before dispatching from the factory, regulates and control the initial torsion of spring, in order to satisfy big moment of torsion service environment demand.
