Fig. 2 is plan structure schematic diagram of the present invention;
Fig. 3 is the structural representation of elongate structure;
In figure: 1, speed reducer output shaft, 2, flat key, 3, deep groove ball bearing, 4, extension shaft, 5, sleeve, 6, drive pulley, 7, speed reducer support, 8, speed reducer base plate.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As Fig. 1-3, a kind of testing machine output shaft elongate structure, comprise speed reducer output shaft 1, be fixed on the drive pulley 6 of speed reducer output shaft 1 outside and be positioned at speed reducer output shaft 1 elongate structure below by flat key 2, described drive pulley 6 is for being divided into upper and lower two-part hollow cylindrical structure, upper part internal diameter is less than lower part internal diameter, speed reducer output shaft 1 is positioned at part on drive pulley, and elongate structure is positioned at part under drive pulley; Described elongate structure comprises that extension shaft 4, two are enclosed within the deep groove ball bearing 3 of extension shaft 4 outsides and one and are enclosed within extension shaft 4 outsides and the sleeve 5 between two deep groove ball bearings 3, the inner circle of deep groove ball bearing 3 is withstood at sleeve 5 two ends, and elongate structure is fixed on by the cylindrical of deep groove ball bearing 3 in the lower part of drive pulley 6; Have a columnar speed reducer support 7 in the outside of drive pulley 6, the lower end of speed reducer support 7 and extension shaft 4 links together.
In the present embodiment, extension shaft 4 is made up of three hollow cylinders that are arranged above and below, and the external diameter of three hollow cylinders closes and is: R
intermediate cylindrical>R
upper cylinder>R
lower cylinder, on intermediate cylindrical, being provided with several screw holes, lower cylinder is through the circular hole being arranged on speed reducer support, and fastening screw trip bolt links together both by the screw hole on speed reducer support and intermediate cylindrical.In the present embodiment, speed reducer support 7 is with upper edge, and upper edge is provided with screw hole, and fastening screw trip bolt links together speed reducer support 7 and speed reducer base plate 8 by screw hole.
Working principle: in the time that speed reducer rotates, output shaft 1 is by rotating speed and transmission of torque to drive pulley 6, and the endoporus overhanging portion of drive pulley 6 supports by the less deep groove ball bearing 3 of pivoting friction resistance.Deep groove ball bearing 3 passes to radial force on the speed reducer support 7 that intensity is higher by extension shaft 4, has finally ensured drive pulley 6 steadily transmission in the situation that of high capacity.
