Description
Technical field
The present invention relates to a kind of break, particularly relate to the clutch brake that a kind of harbour Large Electric machinery uses.
Background technique
Existing inertia brake adopts concavo-convex helicoid to be main actions mechanism, it must have a limit stoper to limit to open distance, make to create very large axial force between concavo-convex helicoid, position-limit mechanism have employed the impact of axial force when rubber combined nut is walked to cushion, when load changes (such as track deformation, wind-force etc.), rubber decrement in compound nut can change because of stressed change, thus between concavo-convex helicoid, form relative sliding, causes noise and wearing and tearing; In horizontal inertia brake, friction plate can not be located when opening and be thrown off completely, makes friction plate produce invalid wearing and tearing, affects the working life of friction plate; Due to concavo-convex helicoid feature, make break adjustment become complicated, layman cannot dismounting and adjustment, and user's maintenance difficulties is strengthened; Driving side for moving back and forth spline housing, for ore operation harbour, poor sealing; Each lubricating point lubricating difficulties.
Summary of the invention
In order to the deficiency in solving the problem, the invention provides a kind of clutch brake.
For solving above technical problem, the technical solution used in the present invention is: a kind of clutch brake, comprise input shaft, output shaft, output sleeve, input shaft is supported on input shaft and supports, and input shaft is meshed by the output shaft external splines of input shaft internal spline and output shaft;
The active top key tooth of input shaft, the driven of output shaft are separated top key tooth and correspond to initiatively top, driven convex, the concave point being separated top respectively.
Input shaft counterclockwise or when turning clockwise, initiatively top salient point all promotes driven separation top salient point, makes it along output shaft outwards movement, thus promote the resilient separation lever that release bearing presses to braking device, and the break of braking device is opened; When input shaft is unpowered, the resilient separation lever of braking device can push release bearing open, automatic impaction brake disc; When braking, the platen of braking device inside compresses the supporting surface that brake disc supports in output shaft, plays braking action.
Output sleeve is coupled by spline with output shaft, and the end of output sleeve is female thread structure, and by screwing in inner nut, tension output shaft supports inner tapered roller bearing.
Present invention, avoiding the defect using electric power or electric fluid power to promote, eliminating the cost that wiring causes increases, and reduces port mechanism design difficulty, noise and wearing and tearing are little, longer service life; Dismounting is easy to adjust, easily safeguard; Good sealing effect, each lubricating point lubricate.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the cooperating structure schematic diagram of input shaft internal spline of the present invention and output shaft external splines.
Fig. 3 is the right flank view of braking device in Fig. 1.
In figure: 1, input shaft; 2, input shaft supports; 3, driven separation top; 4, release bearing; 5, braking device; 6, output shaft supports; 7, output sleeve; 8, output shaft; 9, tapered roller bearing; 10, input shaft internal spline; 11, output shaft external splines; 12, resilient separation lever.
Embodiment
As shown in Figure 1-Figure 3, the present invention includes input shaft 1, input shaft support 2, driven separation top 3, release bearing 4, braking device 5, output shaft support 6, output sleeve 7, output shaft 8, tapered roller bearing 9, input shaft internal spline 10, output shaft external splines 11 and resilient separation lever 12.
As shown in Figure 2, input shaft 1 is supported on input shaft and supports on 2, and input shaft 1 is meshed by the output shaft external splines 11 of input shaft internal spline 10 and output shaft 8; The active top key tooth of input shaft 1, the driven of output shaft 8 are separated top key tooth and correspond to initiatively top, driven convex, the concave point being separated top respectively.
When no matter input shaft 1 is counterclockwise or when turning clockwise, initiatively top salient point all can promote driven separation top salient point, make it along output shaft outwards movement, thus promote the resilient separation lever 12 that release bearing 4 presses to braking device 5, the break of braking device 5 is opened.When input shaft 1 is unpowered, the resilient separation lever 12 of braking device 5 can push release bearing 4 open, automatic impaction brake disc.
Brake disc adopts the automobile clutch driven disc structure of band vibration damper, and the internal spline of braked-disc hub coordinates with the external splines of output shaft, and when braking, the platen of braking device 5 inside compresses brake disc and supports on the supporting surface of 6 in output shaft, plays braking action.
Output sleeve 7 is coupled by spline with output shaft 8, and the end of output sleeve 7 is female thread structure, by screwing in inner nut, plays the effect that tension output shaft supports the tapered roller bearing 9 of 6 inside; Output sleeve 7 also plays the effect connecting external reducer simultaneously.
Design principle of the present invention and advantage:
1, the numerous and diverse degree of Finishing of Machinery in Large-Scale Port equipment de-sign is reduced.The present invention can avoid existing disc type, block formula, band brake must use the defect of electric power or the promotion of electric fluid power; Save the cost increase that power wiring causes, reduce port mechanism design difficulty.
2, current inertia brake Problems existing is overcome: as relied on frictional force transmitting torque problem, lubrication problem, sealing problem, Use Adjustment problem, and there is damping mechanism, the stress that when being particularly useful for solving gantry crane operation, steel structure produces cannot release And Spread of Solute.
3, power consumption is reduced.Because clutch brake is pure mechanical brake, the present invention adopts steel ball and curved surface to rely on main motor Unscrew break, and utilize long spline tooth to transmit the power of master and slave moving axis, break is once open, motor energy consumes minimum, so can reduce power consumption.
Above-mentioned mode of execution is not limitation of the present invention; the present invention is also not limited in above-mentioned citing; the change that those skilled in the art make within the scope of technological scheme of the present invention, remodeling, interpolation or replacement, also all belong to protection scope of the present invention.
