Abstract
The present invention relates to one kind can be realized driving link bi-directional drive, the two-way engagement of driven member；Driven member bi-directional drive, the double rolling key clutch of driving link bidirectional overtaking, in particular to ball ramp type double rolling key clutch.In existing double rolling key clutch, mainly there are roller double rolling key clutch and Wedge-type bi-directional overrunning clutch, but the function that they are realized is driving link rotation, realizes two-way engagement；Driven member rotation, realizes bi-directional braking function, and two kinds of double rolling key clutch cannot achieve driven member driving, bidirectional overtaking function.The present invention is coaxially installed with driving link and jackshaft in shell, has several around circumferentially distributed bellmouth in the opposite disk of the two, and steel ball is clamped between driving link and jackshaft by jackshaft under the action of the spring；It is associated between the jackshaft and driven member by friction component.Structure novel prevents unintentional engagement under the conditions of vibratory impulse, there is fault-tolerant ability.
Description
Technical field
The present invention relates to one kind can be realized driving link bi-directional drive, the two-way engagement of driven member；Driven member bi-directional drive, it is main
The double rolling key clutch of moving part bidirectional overtaking, in particular to ball ramp type double rolling key clutch.
Background technique
Cargo door is opened there are two types of operating mode, a kind of electric opening, a kind of manually opened.Determining manually opened use
Under the premise of driven by quill shaft, how to solve in the case where rotation flexible axle does not increase in addition manual operation manually, product can be certainly
It is dynamic to realize engagement function and transmit torque realization cargo door unlatching.Simultaneously during electric opening, product is realized automatically to be surmounted,
Flexible axle does not rotate.
In existing double rolling key clutch, mainly have roller double rolling key clutch and Wedge-type bidirectional overtaking from
Clutch, but the function that they are realized is driving link rotation, realizes two-way engagement；Driven member rotation, realizes bi-directional braking function,
Two kinds of double rolling key clutch cannot achieve driven member driving, bidirectional overtaking function.
Summary of the invention
Double rolling key clutch of the invention can be realized driving link and drive two-way engagement, and driven member drives bidirectional overtaking
Function.
One bulb ramp type double rolling key clutch, is coaxially installed with driving link and jackshaft, the two is opposite in shell
Disk on have it is several around circumferentially distributed bellmouth, jackshaft under the action of the spring by steel ball be clamped in driving link and in
Between between axis；It is associated between the jackshaft and driven member by friction component.
The friction component includes the movable friction plate being mounted on jackshaft outer surface, and is mounted on driven member inner surface
On static friction plate.
One end of the jackshaft is connect with torquer component, when the initial stage driven to driving link, is led to
It crosses the torquer component and provides opposing torque to jackshaft.
The driving link, jackshaft and driven member pass through bearing support.
When driving driving link, two-way engagement function can be realized；When driving driven member, bidirectional overtaking function can be realized
Energy.
The present invention is applied in airplane cargo doors, and driving link connects manual mode, and driven member connects electric model, works as electric model
When, manual mode does not work, and stationary, this greatly improves flexible axle equivalent life in manual mode.When manual mode operation, it is not necessarily to
Other mechanism and peripheral operation realizes automatic engagement by the rotary motion of driving link, reduces the complexity of mechanism, mitigate
Weight, the requirement of hatch door can be opened by meeting civil aircraft single stepping.
The utility model has the advantages that structure novel, design is light and handy, and attended operation is convenient, while increasing torquer, prevents from shaking
Unintentional engagement under the conditions of dynamic impact, there is fault-tolerant ability.Suitable for working in double modes mechanism, market prospects are extensive, have very big
Economic Application value.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of ball ramp type double rolling key clutch of the present invention.
Specific embodiment
Ramp type double rolling key clutch of the invention, including driving link 1, jackshaft 2, friction component 3, driven member 4, steel
The components such as ball 5, torquer component 6, spring 7 and bearing 9.Driving link 1 is connect with jackshaft 2 by steel ball 5, and spring 7 is pressed
Tight jackshaft 2, is adjacent to it with driving link 1.Steel ball 5 is mounted in driving link 1 and the bellmouth of 2 end face of jackshaft.Jackshaft 2
The other end is connect by spline with torquer 6, is associated with by friction component 3 with driven member 4 in central region.Friction component
3 are made of movable friction plate and static friction plate, and static friction plate connect by spline with jackshaft 2, movable friction plate pass through spline and from
Moving part 4 connects.
The clutch is able to achieve two kinds of functions:
Engagement function: when driving link 1 rotates clockwise or counterclockwise, steel ball pushes jackshaft 2 to make 3 knot of friction component
It closes, generates enough moment of frictions and driven member 2 is driven to rotate in same direction, realize two-way engagement function.Transcendent function: when driven member 4
It rotates clockwise or counterclockwise, when driving link 1 does not input, since jackshaft 2 compresses driving link under the action of spring 7 at this time
1, so that friction component 3 is not bound with, movable friction plate is rotated with driven member 4 in friction component 3 at this time, and static friction plate does not turn
Dynamic, so that jackshaft 2 does not rotate, driving link 1 is static, realizes bidirectional overtaking function.
