For the defect of prior art, the technical problems to be solved in the utility model is: a kind of speed reducer output shaft length extension device under particular service requirement, the speed reducer output shaft of standard model being lengthened is provided.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of speed reducer output shaft length extension device, comprise speed reducer output shaft, be fixed on the drive pulley of speed reducer output shaft outside and be positioned at the elongate structure below speed reducer output shaft by flat key, described drive pulley 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 is positioned at part on drive pulley, and elongate structure is positioned at part under drive pulley; Described elongate structure comprises extension shaft, two deep groove ball bearing and sleeves that are enclosed within outside extension shaft and between two deep groove ball bearings that are enclosed within outside extension shaft, the inner circle of deep groove ball bearing is withstood at sleeve two ends, and elongate structure is fixed on by the cylindrical of deep groove ball bearing in the lower part of drive pulley; Have a columnar speed reducer support in the outside of drive pulley, the lower end of speed reducer support and extension shaft links together.
Preferably, extension shaft 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.
Preferably, described speed reducer support is with upper edge, and upper edge is provided with screw hole, and fastening screw trip bolt links together speed reducer support and speed reducer base plate by screw hole.
Beneficial effect
The utility model has increased the elongate structure being made up of extension shaft, sleeve and deep groove ball bearing, and the length of speed reducer output shaft is increased, and has met the requirement of actual use, and has saved the special customized sky high cost bringing.

Fig. 2 is plan structure schematic diagram of the present utility model;
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 utility model 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.
It should be noted last that, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
