Abstract
The utility model relates to a lowering speed-limiting device for a lifeboat. The lowering speed-limiting device for the lifeboat comprises a static casing, a speed-limiting weight, a spring and a weight rotating shaft, and is characterized by further comprising a one-way overrunning coupler, wherein the one-way overrunning coupler includes an outer ring, a star shaft and balls, and is arranged in the speed-limiting casing; the weight rotating shaft penetrates an eye plate to connect the speed-limiting weight onto the outer ring of the one-way overrunning coupler; and one end of the spring is connected with one end of the speed-limiting weight, and the other end of the spring is connected with the outer ring. The utility model has the advantage that the ascending speed of the lifeboat is not impacted.
Description
Technical field
The utility model relates to a kind of speed-limit device, relates in particular to a kind of life boat and transfers speed-limit device.
Background technology
Present life boat is transferred speed-limit device and is comprised static housing, imput shaft, pouring weight, spring, pouring weight turning cylinder; Imput shaft is installed in the static housing, and pouring weight one end is installed on the imput shaft through the pouring weight turning cylinder, and an end of pouring weight and an end of spring are connected, the other end of spring be installed on the imput shaft, pouring weight middle part is the friction position; Because pouring weight is to be connected with imput shaft through the pouring weight turning cylinder, when imput shaft is rotated, drive the pouring weight rotation thus; Pouring weight is because action of centrifugal force and static housing friction; Spring produces the friction that predetermincd tension is controlled pouring weight and static housing to the pulling of pouring weight simultaneously, thus the control speed drive shaft; Because the device of control life boat lowering velocity is mounted on the winch gear of life boat ship; When the decline life boat, can play the speed limit effect, at the lifting life boat time, also can limit the ascending velocity of life boat equally.
Summary of the invention
To above-mentioned shortcoming, the utility model purpose is to provide a kind of life boat that does not influence the life boat ascending velocity to transfer speed-limit device.
The technology contents of the utility model is: a kind of life boat is transferred speed-limit device; Comprise static housing, speed limit pouring weight, spring, pouring weight turning cylinder; Going characteristic is that it also comprises mono-directional overrun clutch; Mono-directional overrun clutch comprises outer ring, star axle and ball, and mono-directional overrun clutch is arranged in the speed limit shell, and the speed limit pouring weight is connected on the outer ring of mono-directional overrun clutch with the pouring weight turning cylinder through eye plate; Spring one end with speed limit pouring weight one end be connected, the other end of spring is connected with the outer ring.
The advantage that is compared with prior art had of the utility model is: make the speed limit pouring weight can only unidirectional rotation through mono-directional overrun clutch; Thereby the utility model is only worked when transferring life boat; When the rising life boat, the high speed that does not influence life boat rises.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
A kind of life boat as shown in Figure 1 is transferred speed-limit device; Comprise speed limit shell 1, speed limit pouring weight 2, spring 3, pouring weight turning cylinder 4; It is characterized in that it also comprises mono-directional overrun clutch 5; Mono-directional overrun clutch 5 comprises outer ring 5.1, star axle 5.2 and ball 5.3, and mono-directional overrun clutch 5 is arranged in the speed limit shell 1, and speed limit pouring weight 2 usefulness pouring weight turning cylinders 4 are connected on the outer ring 5.1 of mono-directional overrun clutch 5 through eye plate 6; Spring 3 one ends with speed limit pouring weight 2 one ends be connected, the other end of spring 3 is connected with outer ring 5.1.
