Abstract

The invention discloses a clutch type brake. The clutch type brake comprises an input shaft, an output shaft and an output shaft sleeve, wherein the input shaft is supported onto an input shaft support and is meshed with an output shaft outer spline of the output shaft through an input shaft inner spline; driving ejector key teeth of the input shaft and driven separation ejector key teeth of the output shaft correspond to convex and concave points of a driving ejector and a driven separation ejector respectively. According to the clutch type brake, the defect of electric or electro-hydraulic pushing is overcome, cost increase caused by wiring is eliminated, and the design difficulty of a steel structure is reduced. The clutch type brake is low in noise, small in abrasion, longer in service life, convenient to assemble, disassemble and adjust, easy to maintain, good in sealing effect and good in lubrication of each lubricating point.

Description

A kind of clutch brake

Technical field

The present invention relates to a kind of break, relate in particular to the clutch brake that a kind of harbour Large Electric machinery uses.

Background technique

It is main actuating mechanism that existing inertia brake adopts concavo-convex helicoid, it must have a limit stoper to limit to open distance, make to have produced between concavo-convex helicoid very large axial force, the impact of axial force when position-limit mechanism has adopted rubber combined nut with buffering walking, when load changes (such as track deformation, wind-force etc.), rubber decrement in compound nut can change because of stressed variation, thereby forms relative sliding between concavo-convex helicoid, causes noise and wearing and tearing; In horizontal inertia brake, friction plate can not be located and be thrown off completely when opening, and 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 is for moving back and forth spline housing, for ore operation harbour, poor sealing; The lubricated difficulty of each lubricating point.

Summary of the invention

For the deficiency in addressing the above 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 above, and input shaft is meshed by the output shaft external splines of input shaft internal spline and output shaft;

The driven separated top key tooth of the active top key tooth of input shaft, output shaft is corresponding initiatively protruding, the concave point on top, driven separated top respectively.

Input shaft counterclockwise or while turning clockwise, initiatively top salient point all promotes driven separated top salient point, and it is outwards moved along output shaft, thereby promotes 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 be pushed 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 and output shaft are coupled by spline, and the end of output sleeve is female thread structure, and by screwing in inner nut, tension output shaft supports inner tapered roller bearing.

The present invention has avoided the defect of using electric power or electric fluid power to promote, and the cost increase that having saved connects up causes, has reduced port mechanism design difficulty, noise and wearing and tearing are little, longer service life; Dismounting is easy to adjust, easily maintenance; 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. 3 is the right flank view of braking device in Fig. 1.

In figure: 1, input shaft; 2, input shaft supports; 3, driven separated 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 separated 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 driven separated top key tooth of the active top key tooth of input shaft 1, output shaft 8 is corresponding initiatively protruding, the concave point on top, driven separated top respectively.

When input shaft 1 no matter be counterclockwise or while turning clockwise, initiatively top salient point all can promote driven separated top salient point, it is outwards moved along output shaft, thereby 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 be pushed release bearing 4 open, automatic impaction brake disc.

Brake disc adopts the automobile clutch driven disc structure with 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 on the supporting surface of output shaft support 6, 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 that connects outside retarder simultaneously.

Design principle of the present invention and advantage:

1, reduce Finishing of Machinery in Large-Scale Port equipment and design numerous and diverse degree.The defect that the present invention can avoid existing disc type, piece formula, band brake must use electric power or electric fluid power to promote; Save the cost increase that power wiring causes, reduce port mechanism design difficulty.

2, overcome the problem that current inertia brake exists: as relied on frictional force transmitting torque problem, lubrication problem, sealing problem, use to adjust problem, and thering is damping mechanism, the stress that while being particularly useful for solving gantry crane operation, steel structure produces cannot release And Spread of Solute.

3, reduce power consumption.Because clutch brake is pure mechanical brake, the present invention adopts steel ball and curved surface to rely on main motor Unscrew break, utilizes long spline tooth to transmit the power of master and slave moving axis, once break is opened, 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 giving an example; the variation 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.
