Novel clutch

Abstract

The invention belongs to a novel clutch which can be used in both the fields of mechanical soft start and a brake. The mechanism is provided with a combined improvement mechanism of a roller positioning mechanism of a roller type overrunning clutch and a centrifugal type mechanical clutch mechanism or a combined improvement mechanism of the roller positioning mechanism of the roller type overrunning clutch and a roller type mechanical brake mechanism. The novel clutch is characterized in that a middle centrifugal block mechanism in the centrifugal type mechanical clutch mechanism or a roller tightening mechanism in the roller type mechanical brake mechanism is removed, a roller 7 in the mechanism is tightly attracted on a working position by using a mechanism of a magnet 6 in the roller positioning mechanism of the roller type overrunning clutch, and the positions of an inner star wheel 1 and a cover plate 4 nearby the position of each magnet in the improved centrifugal type mechanical clutch mechanism or the improved roller type mechanical brake mechanism are respectively provided with a leverage 5 which can push away the roller 7 from the working position under the action of initial acting force and can overcome the initial acting force under the action of disengagement acting force to restore the roller 7 to the working position under the action of the magnet 6.

Description

1. Technical field [0001] The invention is a novel clutch which can be used in the fields of soft starting and braking. 2. Background technology [0002] We know that in the mechanical field, the roller overrunning clutch is a commonly used mechanical component, and its basic principle is relatively simple. Using this basic principle, it can not only play the role of an overrunning clutch for power transmission, but also be used as an overrunning clutch. The backstop or the brake is used to produce the braking effect, so the application range is relatively wide. However, we also know that the traditional roller type overrunning clutch also has some unsatisfactory aspects in the design structure, such as the spring ejector mechanism among them, because the spring ejector mechanism will make the ejector pin contact with the mechanism when the mechanism overruns. The rollers generate friction, so that the overrunning speed of the mechanism when used as an overrunning clutch or...

Problems solved by technology

But each of the above three patents or patent application technologies also has certain limitations, for example: although the central centrifugal block mechanism in the centrifugal mechanical clutch mechanism and the roller pressing mechanism in the roller mechanical brake mechanism The circular moving body can be used to tighten the rollers in the mechanism, which greatly reduces the frictional heat generated when the mechanism is overloaded and slipped. However, these schemes are generally of the contact type, and there is still a small amount of friction loss.
