Abstract
The utility model relates to a bidirectional braking mechanism. A rotating disk is arranged in the middle of a driving shaft, a plurality of pawls are evenly distributed on the outer circumference of the rotating disk and fixed through pin shafts, ratchet wheels are respectively arranged on two sides of the rotating disk, the ratchet wheels are arranged on the driving shaft, a plurality of ratchets are evenly distributed on the inner side surfaces of the ratchets, and the ratchets are matched with the pawls. The bidirectional braking mechanism has the advantage that the driving shaft moves to drive a driven shaft, the driving shaft stops, and rotation inertia of the driven shaft is born on an outer cylinder so as to enable rotation inertia to be separated.
Description
Technical field
The utility model relates to a kind of bi-directional braking mechanism.
Background technique
Free wheel device is the basic part that occurs along with the development of electromechanical integrated product, and it is the vitals for transmission of power between prime mover and the working machine or between machine intimate driving shaft and the driven shaft and separation function.It is the conversion that utilizes velocity variations or the sense of rotation of driving and driven part, has the voluntarily device of clutch function.Free wheel device is widely used in the environment such as coal, mine, petrochemical industry, workshop lathe, oil recovery, well-digging, and ambient conditions is more abominable, when existing product stopped at driving shaft, driven shaft can't timely and effectively break away from rotary inertia, affects the working life of product.
The model utility content
The purpose of this utility model provides a kind of bi-directional braking mechanism, and when overcoming driving shaft that prior art exists and stopping, driven shaft makes the deficiency that rotary inertia can't timely and effective disengaging.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of bi-directional braking mechanism, comprise driving shaft, the middle part of described driving shaft is provided with rolling disc, some ratchets evenly distribute on the outer peripheral surface of rolling disc, ratchet is fixed by bearing pin, and the both sides of rolling disc are respectively equipped with ratchet, and ratchet is arranged on the described driving shaft, the inner side surface of ratchet is evenly distributed with some ratchets, and ratchet matches with described ratchet.
The beneficial effects of the utility model are: driving shaft is moving, drives driven shaft, and driving shaft stops, and the driven shaft rotatory inertia then is carried on the urceolus, thereby rotary inertia is broken away from.
Description of drawings
The below is described in further detail the utility model with reference to the accompanying drawings.
Fig. 1 is the plan view of the described bi-directional braking of the utility model embodiment mechanism;
Fig. 2 is the side view of the described bi-directional braking of the utility model embodiment mechanism;
Fig. 3 is the perspective view of the described bi-directional braking of the utility model embodiment mechanism.
Among the figure:
1, driving shaft; 2, rolling disc; 3, ratchet; 4, bearing pin; 5, ratchet; 6, ratchet.
Embodiment
As Figure 1-3, the described a kind of bi-directional braking of the utility model embodiment mechanism, comprise driving shaft 1, the middle part of described driving shaft 1 is provided with rolling disc 2, some ratchets 3 that evenly distribute on the outer peripheral surface of rolling disc 2, and ratchet 3 is fixing by bearing pin 4, the both sides of rolling disc 2 are respectively equipped with ratchet 5, ratchet 5 is arranged on the described driving shaft 1, and the inner side surface of ratchet 5 is evenly distributed with some ratchets 6, and ratchet 6 matches with described ratchet 3.
During concrete the use, ratchet 5 and follower interlock, the outside of driven shaft is provided with urceolus.When driving shaft 1 rotates, driving shaft 1 drives rolling disc 2 and rotates, rolling disc 2 drives ratchet 5 by ratchet 3 and rotates, ratchet 5 drives driven shaft and rotates, when driving shaft 1 stopped operating, driven shaft was rotated further owing to inertia, at this moment, the driven shaft rotatory inertia then is carried on the urceolus, thereby rotary inertia is broken away from.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technological scheme, all drops within the protection domain of the present utility model.
