Description
Technical field
Patent of the present invention is related to a kind of slip clutch, especially a kind of slip clutch with overload protection.
Background technology
Slip clutch is moment of friction frictionally between piece to transmit the clutch of power, the torsion being subject to when clutch
When square is more than self friction torque, friction plate skids, and throw-out-of clutch realizes the function of its clutch.General friction type clutch
Device realizes clutch simply by the moment of friction between friction plate, can so make the service life of friction plate and reduce.
The content of the invention
Patent of the present invention is related to a kind of slip clutch with overload protection, reduces dry grinding when friction plate skids,
Improve clutch service life.
The present invention concrete technical scheme be：Described friction clutch includes housing parts, output shaft, bearing, friction
Secondary, fluting lasso, ball, thrust bearing, compression set, described housing parts are arranged on output shaft by bearing, housing
Be provided with fluting lasso in part, fluting lasso can under housing parts drive with housing parts synchronous rotary, while can be along axle
To motion；Friction pair includes the outside friction disc being arranged in fluting lasso and the inner attrition piece being arranged on output shaft, described
Outside friction disc and inner attrition piece are multi-disc and interlaced arrangement；Radial taper groove, housing parts are provided with described fluting lasso
Semi-circular groove is internally provided with, ball is arranged in the space that semi-circular groove is formed with cone tank, in the presence of semi-circular groove
With housing parts synchronous rotary, compression set includes outer spring seat inner spring seat and the internal compression spring set, its China and foreign countries' bullet
Spring abutment is arranged on output shaft by step, and inner spring seat is contacted with friction pair, and is arranged on fluting lasso by thrust bearing
On.The blowout patche of described inner spring seat and thrust bearing is integrated.
The present invention is decomposed the moment of torsion of input by being provided with fluting lasso, wherein peripheral force driving friction subtask, real
The transmission of existing moment of torsion, and when output end moment of torsion is more than and disengages moment of torsion, axial force moves fluting lasso, acts on compression set
On, it is ensured that friction pair is efficiently separated, and dry grinding situation is not produced.The present invention makes to rub by setting fluting lasso and compression set
The separation of friction pair can be realized at work by wiping clutch, it is to avoid dry grinding when friction plate skids, and be carried out in overload
It is effectively protected, improves clutch service life.
Brief description of the drawings
Fig. 1 is structural representation of the invention；
Fig. 2 is ball mounting structure schematic diagram.
Embodiment
As illustrated, a kind of slip clutch with overload protection includes housing parts 1, output shaft 7, bearing 14, rubbed
Secondary, fluting lasso 11, ball 12, thrust bearing 9, compression set are wiped, described housing parts 1 are arranged on output by bearing 14
On axle 7, fluting lasso 11 is provided with housing parts 1, fluting lasso 11 can be same with housing parts 1 under the drive of housing parts 1
Step rotation, may be axially movable simultaneously；Friction pair includes the outside friction disc 3 being arranged in fluting lasso 11 and is arranged on output shaft
Inner attrition piece 4 on 7, described outside friction disc 3 and inner attrition piece 4 are multi-disc and interlaced arrangement；On described fluting lasso 11
Radial taper groove is provided with, housing parts 1 are internally provided with semi-circular groove, and ball 12 is arranged on semi-circular groove and formed with cone tank
Space in, with the synchronous rotary of housing parts 1 in the presence of semi-circular groove, compression set include outer spring seat 6, inner spring seat
5 are arranged on output shaft 7 with the internal compression spring 8 set, wherein outer spring seat 6 by step, inner spring 5 and friction pair
Contact, and be arranged on by thrust bearing 9 on fluting lasso 11.The blowout patche of described inner spring 5 and thrust bearing 9 is one
Body.
In work, by 3 straight pins on housing parts 1 to clutch input torque, housing parts 1 pass through semicircle
Groove driving ball 12 is acted, and ball 12 is acted on cone tank, and cross-notching lasso 11 is decomposed into the power of axial and circumferential, wherein week
Moved to power driving fluting lasso 11, when output end moment of torsion is less than the disengagement moment of torsion of setting, the driving inner attrition piece of outside friction disc 3
4, and then drive output shaft 7 to rotate, realize that moment of torsion is transmitted.When output end moment of torsion reaches the disengagement moment of torsion of setting, or there is event
When barrier causes the output shaft 7 to block, the axial thrust load of ball 12 presses fluting lasso 11 and is axially moved, and fluting lasso 11 passes through thrust
Bearing 9 is acted on inner spring seat 5, is axially moved inner spring seat 5, is laid down the pretightning force between friction pair, outside friction disc 3
Skid or separate with inner attrition piece 4, compression set and output shaft 7 do not rotate, input idle running realizes the function of overload protection
Effect.
