Problems solved by technology

However, the traditional roller overrunning clutch also has some unsatisfactory aspects in the design structure. For example, the spring ejector pin mechanism in the clutch will cause friction between the ejector pin and the roller when the mechanism overruns, so that the mechanism acts as an overrunning clutch. The overrunning speed when used or the idling speed when used as a backstop will be affected to a certain extent, which will cause a waste of energy

Embodiment Construction

[0011] As can be seen from Figure 1, there is a centrifugal mechanical clutch mechanism or a roller mechanical brake mechanism in the mechanism. In the present invention, the middle centrifugal block mechanism in the centrifugal mechanical clutch mechanism or the roller top in the roller mechanical brake mechanism The tightening mechanism is removed, and on the contact surface of the main centrifugal block mechanism in the centrifugal mechanical clutch mechanism or the roller pad mechanism in the roller mechanical brake and the roller 2, a position and the normal working position of the roller 2 are set. Correspondingly, a part of the arc on the roller 2 is recessed therein, and the length direction of the inward recess is parallel to the arc groove of the axial centerline of the mechanism.

[0012] The centrifugal block 4 refers to the main centrifugal block in the centrifugal mechanical clutch mechanism, and refers to the roller pad mechanism in the roller mechanical brake me...

Abstract

The invention relates to a mechanical clutch which is provided with a centrifugal mechanical clutch mechanism or pin roller type mechanical brake structure. According to the mechanical clutch, a middle centrifugal block mechanism in the centrifugal mechanical clutch mechanism or a pin roller tightening mechanism in a pin roller type mechanical brake is removed; an inwards-concave arc with the position corresponding to the normal pin roller working position is manufactured on the contact face of the a main centrifugal block mechanism of the centrifugal mechanical clutch mechanism or a pin roller heel block mechanism in the pin roller type mechanical brake and a pin roller, and an arc at the upper portion of the pin roller can sink into the inwards-concave arc; when the motor running speed is over, a ball and a pin roller can rotate in the arc, and therefore the overload protection effect is achieved; and then, the ball and the pin roller are in pure rolling friction in the arc, the wasted heat energy is relatively small, and meanwhile the service life of the mechanism is intangibly prolonged.

Description

technical field [0001] The invention relates to a clutch, to be precise, a mechanical clutch. Background technique [0002] In the mechanical field, the roller overrunning clutch is a relatively common mechanical component, and its basic principle is relatively simple. Using this basic principle, it can not only play the role of an overrunning clutch to transmit power, but also can be used as a backstop. Or the brake to produce the braking effect, so it has a wide range of applications. However, the traditional roller overrunning clutch also has some unsatisfactory aspects in the design structure. For example, the spring ejector pin mechanism in the clutch will cause friction between the ejector pin and the roller when the mechanism overruns, so that the mechanism acts as an overrunning clutch. The overrunning speed when used or the idling speed when used as a backstop will be affected to a certain extent, which will cause a waste of energy. Contents of the invention [...
