Embodiment approach

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] refer to Figure 1-2 As shown, an automatic speed-limiting clutch provided by the present invention includes a fixed outer ring 1, an inner ring 2 that cooperates with the outer ring 1 and rotates along its axis, and is arranged between the outer ring 1 and the inner ring 2 The two speed-limiting brake blocks 3 that can move radially outwards can also have more than two speed-limiting brake blocks 3, and the speed-limiting brake blocks 3 are evenly clamped on the outer surface of the inner ring 2, and It can rotate together with the inner ring 2. The outer surface of the speed-limiting brake block 3 is in clearance fit with the inner surface of the outer ring 1, and the corresponding ends of the adjacent speed-limiting brake blocks 3 are respectively connected by a tension spring 4, optimally, the adjacent speed-limiting brake...

Abstract

The invention discloses an automatic speed-limiting clutch which comprises a fixed outer ring, an inner ring and at least two speed-limiting brake blocks. The inner ring is matched with the outer ring and rotates along the axis of the outer ring, the speed-limiting brake blocks capable of radially moving outwards are arranged between the outer ring and the inner ring, the inner side faces of the speed-limiting brake blocks are clamped on the outer surface of the inner ring, the speed-limiting brake blocks can rotate along with the inner ring, the outer side faces of the speed-limiting brake blocks are in clearance fit with the inner surface of the outer ring, and corresponding ends of the adjacent speed-limiting brake blocks are respectively connected through a tension spring. The speed-limiting brake blocks arranged between the inner ring and the outer ring of the clutch tightly holds the inner surface of the outer ring under the action of centrifugal force, the speed of the inner ring is automatically limited, and the automatic speed-limiting clutch has the advantages of fine reliability, simple structure, low cost and the like.

Description

technical field [0001] The present invention relates to a clutch, and more particularly, the present invention relates to an automatic speed-limiting clutch. Background technique [0002] In the field of wind power generation, when the normal wind speed of the wind turbine makes the main shaft of the fan within 1500-1800r / Min, it is the best ratio of torque and speed. The greater the wind force, the faster the spindle speed. If the spindle speed is not controlled at 1800r / Min, the entire fan frame will have an accident. And in the field of agricultural and forestry machinery and high-rise emergency slow-down devices, high-altitude track feeders and emergency rescue slow-down devices descend from high altitudes to the ground. Due to the action of gravity, the speed will become faster and faster, so it is necessary to slow down the equipment to prevent danger. Contents of the invention [0003] The purpose of the present invention is to provide an automatic speed-limiting c...
