Abstract

The utility model discloses a clutch type brake which comprises an input shaft, an output shaft and an output shaft sleeve. The input shaft is supported by an input shaft support, and the input shaft is meshed with an output shaft outer spline of the output shaft through an input shaft inner spline. A drive top key tooth of the input shaft and a driven separation top key tooth of the output shaft correspond to a convex point of a drive top and a concave point of a driven separation top respectively. The clutch type brake overcomes the defect that pushing is carried out through electric power or electric liquid power, cost increase caused by wire arrangement is removed, the design difficulty of port mechanisms is lowered, noise and abrasion are little, service life is longer, detaching and adjusting are convenient, maintaining is easy, the sealing effect is good, and lubrication of all lubricating points is good.

Description

A kind of clutch brake

Technical field

The utility model relates to a kind of break, relates 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.

Model utility content

For the deficiency in addressing the above problem, the utility model provides a kind of clutch brake.

For solving above technical problem, the technical solution adopted in the utility model 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 separation top key tooth of the active top key tooth of input shaft, output shaft is corresponding initiatively protruding, the concave point on top, driven separation top respectively.

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 utility model has been 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 utility model is described in further detail.

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the cooperating structure schematic diagram of input shaft internal spline of the present utility model 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 utility model comprises 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 driven separation 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 separation top respectively.

When input shaft 1 no matter be counterclockwise or while turning clockwise, initiatively top salient point all can promote driven separation top salient point, it is outwards moved along output shaft, thereby promotion release bearing 4 press to the resilient separation lever 12 of braking device 5, and 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 tension output shaft and support the effect of 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 utility model and advantage:

1, reduce Finishing of Machinery in Large-Scale Port equipment and design numerous and diverse degree.The defect that the utility model 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 utility model 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 to restriction of the present utility model; the utility model is also not limited in above-mentioned giving an example; variation, remodeling, interpolation or replacement that those skilled in the art make within the scope of the technical solution of the utility model, also all belong to protection domain of the present utility model.
