Description
Technical field
The present invention relates to a kind of clutch, particularly a kind of freewheel clutch.
Background technology
Transmission mechanism is there are during load torque, after transmission stops or motor powers off, it may occur that reversal.It is anti-
Non-return forwarding life, can use freewheel clutch or cannot can also use the transmission dress that cannot be reversed against the driving motor of transmission
Put（It can be such as driven with the worm-drive of self-locking or slip screw）And electromagnetism or liquid braking device.
Freewheel clutch is widely used as a kind of common anti-reverse-rotation device.Mono-directional overrun clutch can be complete
During into ball leading screw driving when preventing unidirectional reversal, but being applied to Double-directional rotary situation, such as vertical orientations, need
Increase friction mechanism and produce the moment of resistance to offset stall torque.When stall torque has impact or oscillating load, rub mechanism
The moment of resistance that can be generated should be greater than maximal reversal torque to guarantee reliably to prevent from reversing.But such a design will be so that reversing
When torque is smaller, transmission mechanism need to increase larger torque to overcome the moment of resistance, cause power consumption to increase, structure size increase etc.
Defect.When there is stall torque effect, roller or wedge block will be unable to normally open and produce discontinuously dynamic double rolling key clutch
Make phenomenon.
The content of the invention
It is an object of the invention in place of overcome the deficiencies in the prior art, and provide it is a kind of can two-way anti-reverse surmount from
Clutch.
A kind of freewheel clutch, includes double rolling key clutch, lower wearing piece, inner attrition piece, upper friction plate, pressurization bullet
Spring, gland and mono-directional overrun clutch, the lower wearing piece, inner attrition piece, upper friction plate, pressing spring, gland and unidirectional
Freewheel clutch may be contained within bidirectional overtaking from device housing, and double rolling key clutch output terminal and mono-directional overrun clutch are coaxial
It is sequentially arranged, inner attrition piece is set in mono-directional overrun clutch periphery, and upper friction plate, lower friction plate are sequentially sleeved at inner attrition piece
Periphery, the annular projection of a circle is provided with the periphery of inner attrition piece, upper and lower friction plate is distributed in inner attrition piece ring-type respectively
Above and below raised, there is gap between the outer circumferential surface of upper and lower friction plate and inner attrition piece, freewheel clutch has further included gland,
Gland is arranged at below the top of upper friction plate and the baffle ring of double rolling key clutch housing, is set between gland and upper friction plate
Pressing spring is equipped with, there is gap arrangement between one-way clutch and double rolling key clutch.
When equipment is in halted state, i.e., when input torque is zero, the stall torque produced by load is through mono-directional overrun
Clutch is balanced by static friction torque again；When the stall torque for having the generation of greater impact load in load causes moment of friction insufficient
During balancing, then moment of friction is produced by double rolling key clutch and is undertaken；Positive turn is produced when there is greater impact load in load
During square, moment of friction is also produced by double rolling key clutch and is undertaken.
When rotating forward work, it is inverse to overcome that the input torque of rotating forward through double rolling key clutch is directly output to operating mechanism
Torque passing power, at this time mono-directional overrun clutch be in disengaged condition；When inverting work, stall torque makes mono-directional overrun
Clutch close, dynamic friction torque is completely counterbalanced by stall torque at this time, also additionally produce less forward direction torque make it is two-way
Freewheel clutch can work normally.When in operation state, if having shock loading input, produced by double rolling key clutch
Raw moment of friction undertakes.
In summary, present invention advantage following compared with prior art：
The present invention freewheel clutch, have it is simple in structure, be used conveniently and safely the advantages of reliable.
Brief description of the drawings
Fig. 1 is the structure diagram of the freewheel clutch of the present invention.
1 double rolling key clutch of label declaration, 2 times wearing pieces, 3 inner attrition piece, 4 upper friction plate, 5 pressing spring, 6 gland
7 and 8 input shaft of mono-directional overrun clutch, 9 output shaft.
Embodiment
The present invention is described in more detail with reference to embodiment.
Embodiment 1

Bidirectional overtaking is may be contained within from device housing to freewheel clutch, and double rolling key clutch output terminal and mono-directional overrun clutch are same
Axis is sequentially arranged, and inner attrition piece is set in mono-directional overrun clutch periphery, and upper friction plate, lower friction plate are sequentially sleeved at interior friction
The periphery of piece, the annular projection of a circle is provided with the periphery of inner attrition piece, and upper and lower friction plate is distributed in inner attrition piece ring respectively
Above and below shape protrusion, there is gap, freewheel clutch has further included pressure between the outer circumferential surface of upper and lower friction plate and inner attrition piece
Lid, gland are arranged at below the top of upper friction plate and the baffle ring of double rolling key clutch housing, gland and upper friction plate it
Between be provided with pressing spring, there is gap arrangement, lower friction plate is against two-way between one-way clutch and double rolling key clutch
On the step of freewheel clutch, upper friction plate, the annular projection of inner attrition piece and lower friction plate are pressed in two-way surpass using gland
More on the step of clutch, inner attrition piece and mono-directional overrun clutch tight fit, the outer circumferential surface of the annular projection of inner attrition piece with
The inner peripheral surface of double rolling key clutch has gap.The input terminal of double rolling key clutch is installed on outside input shaft 8, bidirectional overtaking
The output terminal and mono-directional overrun clutch of clutch are installed on outside output shaft 9.
The not described part of the present embodiment is same as the prior art.
