Embodiment 1

[0016] see Figure 1 ~ Figure 3 , there is a main shaft (1) in the figure, the inner tooth turntable (2) is fixed on the main shaft (1), and the inner tooth turntable (2) is equipped with a speed-limiting slider (3) with a guide groove in the middle and teeth at both ends, An organic seat (5) and a machine cover (4) are installed on the main shaft (1) outside the internal tooth turntable (2), and a pair of bearings (7) rising into the middle of the speed-limiting slider are fixed on the machine cover (4); the machine cover (4) are fixed on the support (5), and they constitute the speed-limiting mechanism; Quantitative lubricating fluid is filled in the inner cavity of the speed-limiting mechanism. When in use, as long as the heavy objects or personnel are tied to the end of any supporting mechanism of this embodiment raised from the main shaft (1), the speed-limiting slide block with teeth (3) can be moved to limit the internal tooth turntable by using gravity to descend or sl...

Embodiment 2

[0018] see Figure 4 and image 3 In the figure, a main shaft (1) is fixed on the main shaft (1) with an internal tooth turntable (2), and a toothed speed limiting slider (3) is installed in the inner tooth turntable (2), and the inner tooth on the main shaft (1) A machine cover (4) and a machine base (5) are installed outside the turntable (2), and two bearings (7) are installed on one end of the tooth surface of the machine cover (4) on the inner gear turntable; the other end of the main shaft (1) is installed with Connection plate (8) etc. As long as the mechanism of the present embodiment is fixed during use, then the connecting plate (8) is combined with other fixed structures, so that heavy objects or personnel etc. can be tied on it, so that the speed limit can be implemented by its gravity and has fallen.

Abstract

The invention discloses a novel speed-limiting mechanism, which consists of a main shaft, on which an inner-tooth turntable is fixed, and a speed-limiting slider with a guide groove in the middle and teeth on both ends is installed in the inner-tooth turntable. An organic base and a machine cover are installed outside the gear turntable, and a pair of bearings inserted into the middle of the speed-limiting slider are fixed on the machine cover; the machine cover is fixed on the machine base, and they constitute a speed-limiting mechanism; in the inner cavity of the speed-limiting mechanism Contains a certain amount of lubricating fluid. When the present invention is in use, as long as it is fixed, it can cooperate with the object to carry out the weight drop and speed limit, or hang it on the building, fix it with a steel wire rope or nylon rope at one end and roll it on the supporting reel, and use gravity decrease to achieve the purpose of speed limit. The present invention can also be widely applied to the speed limiting action mechanism and the like when the vehicle slides down.

Description

technical field [0001] The invention relates to a mechanical speed-limiting device, in particular to a novel speed-limiting mechanism. Background technique [0002] There are reducers used in machinery, which reduce the original input speed to the planned requirements through the combination of gears, worm gears, worms, belts, cycloidal pinwheels and other structures to achieve the purpose of deceleration. At present, there are various standards for various reducers, which can be selected by those who need them. At present, no matter what the size of the reducer exists, it needs external power to use, and the volume is relatively large, the structure is also complicated, and the cost is high. [0003] In addition, with the progress of society and the continuous development of science and technology, people's living standards are also constantly improving. At the same time, high-rise buildings in cities and towns are also increasing in the construction industry. Since the ...
