The position that described rotating shaft coordinates with end cap is provided with groove and end cap is fixed, and end cap is provided with circlip for shaft.
Be threaded connection between described rotating shaft and screw putter.
The rotation of adjusting sleeve in described adjusting sleeve is controlled by unilateral bearing.
Described reference seat is fixedly connected with rotating shaft.
Change all constituents of existing product the utility model patent innovation, eliminate torsion spring product, structure is inserted in as Fig. 2,3,4,5 changes adjustment rotating shaft torsion spring structure into unilateral bearing, adjusting sleeve is improved, unilateral bearing is pressed in adjusting sleeve, form bearing unit, then rotating shaft is pressed in bearing unit.Be that adjusting sleeve and turning collar adopt torsion spring to combine before change, after change, in adjusting sleeve, press-fit unilateral bearing, interior adjusting sleeve is inserted in unilateral bearing, form unilateral bearing assembly, play one-way clutch effect. realize by unilateral bearing assembly the unidirectional movement that adjusting sleeve drives rotating shaft;
The antioverloading parts of regulator are improved, cancel Compress Spring, the end axis structure of countershaft changes under the prerequisite not affecting whole height, one plain washer is installed in end, mounting plane bearing on plain washer, internal and external gear clutch sheet is press-fited on plane bearing, whole end cap debug by clutch plate overcoat, forming plane bearing assembly. plane bearing assembly mainly plays antioverloading function in the constant situation of brake clearance, when brake clearance does not need to regulate, pressure arm stirs adjusting sleeve, just adjusting sleeve is skidded mutually with the plane bearing assembly of adjustment cover internal, ensure that adjustment rotating shaft is motionless, thus avoid whole regulator work, prevent the toning of brake process gap.
Rotating shaft and the cooperation place of adjustment end cap are milled out two parallel planes by cylindrical, adjustment end cap just coordinates with rotating shaft, effectively can avoid the motion of adjustment end cap radial direction, at adjustment end caps circlip for shaft, adjustment end cap be fixed, avoid the axial motion of adjustment end cap.

Embodiment
Change all constituents of existing product the utility model patent innovation, eliminate torsion spring product, structure is inserted in as Fig. 2,3,4,5 changes adjustment rotating shaft torsion spring structure into unilateral bearing, adjusting sleeve is improved, unilateral bearing is pressed in adjusting sleeve, form bearing unit, then rotating shaft is pressed in bearing unit.Be that adjusting sleeve and turning collar adopt torsion spring to combine before change, after change, in adjusting sleeve, press-fit unilateral bearing, interior adjusting sleeve is inserted in unilateral bearing, form unilateral bearing assembly, play one-way clutch effect. realize by unilateral bearing assembly the unidirectional movement that adjusting sleeve drives rotating shaft;
The antioverloading parts of regulator are improved, cancel Compress Spring, the end axis structure of countershaft changes under the prerequisite not affecting whole height, one plain washer is installed in end, mounting plane bearing on plain washer, internal and external gear clutch sheet is press-fited on plane bearing, whole end cap debug by clutch plate overcoat, forming plane bearing assembly. plane bearing assembly mainly plays antioverloading function in the constant situation of brake clearance, when brake clearance does not need to regulate, pressure arm stirs adjusting sleeve, just adjusting sleeve is skidded mutually with the plane bearing assembly of adjustment cover internal, ensure that adjustment rotating shaft is motionless, thus avoid whole regulator work, prevent the toning of brake process gap.
Rotating shaft and the cooperation place of adjustment end cap are milled out two parallel planes by cylindrical, adjustment end cap just coordinates with rotating shaft, effectively can avoid the motion of adjustment end cap radial direction, at adjustment end caps circlip for shaft, adjustment end cap be fixed, avoid the axial motion of adjustment end cap.
Clutch bearing assembly is made up of screw putter, adjustment rotating shaft, supporting base, adjusting sleeve, unilateral bearing assembly, interior adjusting sleeve, return spring, clutch plate, end cap etc. in conjunction with single push rod regulator assembly of clutch plane bearing modular construction.
Product adopts unilateral bearing assembly to realize the one-way rotation of adjustment rotating shaft, adopts clutch plane bearing assembly to realize the overload prevention function (skidding function) of regulating mechanism.
When retardation pressure arm presses down, drive adjusting sleeve is rotated, adjusting sleeve rotation can make interior adjusting sleeve rotate under the effect of unilateral bearing, when interior adjusting sleeve is rotated, under the active force of clutch plate and end cap, make adjustment axis of rotation, and then screw putter is outwards screwed out relatively, promotion brake slipper travels forward, and compensates the brake clearance between brake slipper and brake disc, reaches braking effect.
Retardation pressure arm continues to press down; adjusting sleeve and interior adjusting sleeve are rotated; because brake clearance is eliminated; limit the rotation of screw putter and rotating shaft; cause the plane clutch component in end cap to overcome frictional force that return spring provides and rotate (skidding), thus the function reaching that the whole regulator inner body of self-protection do not sustain damage.During pressure arm return, drive adjusting sleeve to rotate, but interior adjusting sleeve can not be rotated under unidirectional rotating shaft effect along with the rotation of adjusting sleeve, pressure arm gets back to initial position.
Torsion spring and Compress Spring is eliminated in this model utility, clutch bearing and plane bearing is adopted to realize single direction rotation and skidding function, greatly improve the reaction sensitivity of product, improve life of product, avoid the many potential risks because spring failure causes.
Whole modular construction advantages of simple, is easy to produce and assembling, and be especially more convenient for maintenance and replacing, be arranged on brake calipers, just mate completely, meet brake gap adjustment function, overall performance and life-span obtain and greatly promote, and quality is more stable.
Clutch bearing assembly of the present utility model is in conjunction with single push rod regulator assembly of plane bearing modular construction, torsion spring will be adjusted cancel, unilateral bearing assembly is adopted to substitute torsion spring, Compress Spring is cancelled, Compress Spring is substituted with clutch plane bearing assembly, completely eliminate spring product due to problems such as the performance degradation after the performance deficiency of Spring Steel Wire itself and Reusability, greatly improve the sensitivity of tune gap and the working life of regulating mechanism, product after improvement does not only affect the unidirectional twisting force of product, and effectively improve antioverloading function, Product processing is very easy and for ease of maintenaince.
The utility model patent is the regulating mechanism of the auto-compensation brake clearance being applied to disk type braker, product adopts unilateral bearing assembly to realize the one-way rotation of adjustment rotating shaft, adopts clutch plane bearing assembly to realize the overload prevention function (skidding function) of regulating mechanism.Be applied in break, the Security of Hoist braking device greatly, stability and working life.
