Inventive description: [Technical field of invention], the belt system of a belt-driven spindle of a time-controlled belt drive spindle 'traditional spindle revolving device, when a belt drive is used, the servo motor drives the drive pulley, and the drive pulley utilizes Friction force V belt, the belt drives the driven pulley to rotate, the idler wheel yaw position on both sides of the belt, and the expansion wire is squeezed, causing the radial force load on the scale _, the rotation precision is not good, and the belt rotates for a long time. It is easy to produce flexure and alkali wear and fracture. _In this correction wiper servo motor Xiang bearing with social moving pulley, eliminate the load force on the motor shaft, and use the timing belt to drive the pulley, no traditional idler compression belt, causing the time gauge π deflection 1 series | Missing, the recording rotation accuracy is improved, and the motor shaft has no warp load, so that the spindle return speed is fixed and the motor life is long. [Prior Art] Please refer to the 'traditional spindle rotation transmission device shown in the figure--, the servo motor drives the drive pulley 29 to rotate, the drive pulley 29 rotates to drive the timing belt %, and the timing belt 36 drives the driven pulley 6 again. The idler pulley 37 on both sides of the belt belt, the idler pulley π • expands to the inner side of the timing belt 36 or outward, as shown in the first figure (8), (9), so that the timing belt 36 on the wire pulley 29 and the driven pulley 6 contact areas and friction 'but the timing belt 36 is prone to deflection or wear and tear under the pressure of the idler 37 for a long time'. The following is an example of a conventional spindle rotating device, please refer to the second figure. Shown. β Patent Patent No. of Taiwan Patent: 〇_763〇, new patent name: two-way transmission design of the wheel driven by the motor using the timing belt, announcement period · 2〇〇0/1〇/〇1, application date: 1999 /04/09 〇' 200804132 Patent Abstract: A drive design that uses a timing belt to drive a vehicle to move forward and backward. The transmission system includes a motor, a pulley and a belt. The two sides of the belt are respectively micro-pressed by two idlers. The idler wheel is pulled by the elastic component, so that the two idler wheels have a mutual movement and synchronous movement by the action of the elastic component, and when the transmission system operates, the action of the elastic component automatically changes the emotional wheel. The varying length of the belt's loose side pressure tension side allows the side to have sufficient tension to avoid slipping, so that the transmission system has a two-way transmission function. • The detailed description of the prior art is shown in the second figure. The second figure (8) shows that the motor drives the wheel through the timing belt. When the transmission system is operated, the belt will have different pressure on both sides. Change 'Finance loose edge is to avoid bribery to avoid slipping, use the idler to oppress the timing belt, see the second _, the idler (four) wheel bearing idler, two idler _ miscellaneous components connected to the double So that (four) wheel pressure on both sides of the Wei belt 'automatically adjust the tension of the timing belt to make it have enough tension to avoid slipping. However, the timing belt is thinned for a long time, and is squeezed or expanded by the mountain wheel to the belt, so that the surface of the timing belt is worn, or the timing belt cannot rotate at high speed due to the influence of the idler pressure, which is the traditional use of the timing belt to drive the main shaft, etc. Missing, based on the above reasons, the design was proposed to improve the lack of conventional idler belts used to control the timing belt. [Summary of the Invention] In the conventional spindle revolving device, when the belt is driven, the motor shaft drives the driving pulley, the driving pulley drives the belt, and the belt is followed by the moving pulley. As described above, the horse's shaft is subjected to excessive force, resulting in the spindle rotation accuracy. Both the belt and the belt are pressed by the idler on both sides of the belt, and the belt is easily worn and broken. Therefore, the design uses the bearing to indirectly drive the drive pulley. The bearing ball can make the drive pulley rotate at a high speed, and does not require the idler to press the timing belt. 7 200804132月匕 has good transmission efficiency, please refer to the third figure for details.

At this point, the entire timing belt 36 drive is completed. The mechanism operation process of the belt tension eliminating device of the timing spindle 16. The timing belt 36 of the design drives the belt tension eliminating device of the working spindle 16, and the application level is quite extensive, and the device can be applied to various devices such as a motor and a pulley. The design utilizes a bearing to indirectly drive the driving pulley 29, and the spindle pulley 29 drives the driven pulley 6 by the timing belt 36, which solves the defect that the belt is easily worn and broken by the idler wheel in the prior art, and the servo motor 26 directly drives the defect. The drive pulley 29 and the motor shaft 261 are subjected to excessive load. The spindle running accuracy is unstable, and the timing belt 36 is used for transmission. There is no problem that the conventional belt slips under high-speed rotation, and the structure is simple, the belt replacement is easy, the spindle shaft diameter can be increased, the rigidity is improved, and the parts are simplified. , reducing costs and other advantages. As described above, this design has excellent practicability in the industry, and is extremely novel, progressive and industrially usable. The above is only a preferred embodiment of the design, and the design is turned over. Limiting the implementation of this design to the 'design', the design changes, and the equivalent changes and modifications are covered by this design patent.
