An automatic transmission pulley

Abstract

The invention relates to an automatic speed-changing belt wheel. The automatic speed-changing belt wheel comprises a wheel body, a fixing shaft, an output shaft and a fixing support; a friction disk fixedly connected with the wheel body is arranged inside the wheel body, the wheel body is connected with the fixing support through a bearing a, the upper end and the lower end of the fixing support are connected with a speed-changing shaft a and a speed-changing shaft b through a bearing c and a bearing d respectively, the speed-changing shaft a and the speed-changing shaft b are provided with a friction wheel a and a friction wheel b capable of sliding along the speed-changing shaft a and the speed-changing shaft b respectively, the friction disk is compressed by the friction wheel a and the friction wheel b, the speed-changing shaft a and the speed-changing shaft b are meshed with output gears through a gear a and a gear b respectively, and the output gears are connected with an output shaft. The automatic speed-changing belt wheel has the advantages that the structure is simple, installation and use are relatively rapid and convenient, damage cannot be caused easily in the using process, the service life is long, the performance is stable, the speed changing range is larger, and the variable speed process is relatively stable.

Description

technical field [0001] The invention relates to an automatic variable speed pulley. Background technique [0002] Now is an era of technology, the mechanical equipment used by people is getting more and more advanced, and the operation is more and more convenient. Among the machines used by modern people, many of them involve speed adjustment, and the speed regulation method has also developed from the original step to stepless. [0003] The current speed regulation method is relatively complicated, such as adding an adjustment piece between the two wheels to make the pulley wider or narrower. Although some pulleys can change speed quickly, they are easily damaged in harsh environments, and some need to be replaced. The whole pulley. For example, the main fan transmission device used in the combine harvester in the field of agricultural machinery has complex and changeable operating objects and environments, and the speed of the corresponding working parts needs to be vari...

[0003] The current speed regulation method is relatively complicated, such as adding an adjustment piece between the two wheels to make the pulley wider or narrower. Although some pulleys can change speed quickly, they are easily damaged in harsh environments, and some need to be replaced. whole pulley

For example, the main fan transmission device used in the combine harvester in the field of agricultural machinery has complex and changeable operating objects and environments, and the speed of the corresponding working parts needs to be variable to adapt to different operating objects and environments. At present, there is no high-quality, low-cost, An adjustable speed transmission device that is not easy to damage, simple, convenient and quick to achieve the purpose of speed change
