Embodiment
Below in conjunction with accompanying drawing and embodiment technological scheme of the present invention is done further to explain, but following content is not used in qualification protection scope of the present invention.
Shown in Fig. 1-2, present embodiment provides a kind of combustion and steam Combined Cycle Unit timing clutch, comprises power input shaft 1, slide block assembly 2, power output ring 3 and two way damper 8.Power input shaft 1 is provided with a series of screw key 4; Sliding assembly 2 is contained on the screw key 4; The both sides of sliding assembly 2 have a clutch tooth 7 and a click structure (comprising ratchet 5, ratchet 6) respectively; Power output ring 3 just is connected with slide block with the click structure through this group clutch tooth 7, and two way damper 8 is arranged between the limiting stopper of sliding assembly 2 and power input shaft 1.
In the present embodiment, two way damper 8 comprises a damping cavity, and these damping cavity both sides all are full of low pressure lubricant oil, and lubricant oil is through four throttle orifice 9 fuel feeding of both sides clutch.
Further, said ratchet 6 adopts the ratchet with speed selection, in solving between installation and spreadable life, output terminal occurs through regular meeting and must keep static and situation (like the jiggering state) that the input end maintenance is rotated.
In the present embodiment, suppose that clutch is in disengaged condition, at this moment the click structure of sliding assembly 2 contact with output ring 3, and clutch tooth 7 and output terminal get loose (like Fig. 1).When input shaft begins to rotate; At first driving sliding assembly 2 through screw key 4 rotates and makes itself and input shaft synchronous; When clutch forward transmitting torque, input shaft rotational speed is inevitable greater than output ring 3 rotating speeds, thereby makes sliding assembly 2 and output encircle 3 click structure engages.This moment, sliding assembly 2 was with relative input shaft axial translation (being that sliding assembly 2 is moved to the left among Fig. 1); The clutch tooth 7 that makes sliding assembly 2 and output encircle 3 progressively meshes; The click structure that while sliding assembly 2 and output ring are 3 gets loose gradually, clutch tooth 7 engagements (like Fig. 2) fully when sliding assembly 2 contact limiting stoppers.Otherwise clutch changes the state of getting loose into from engagement and also has similar procedure.
In the present embodiment, clutch perhaps carries out the transition to the state of getting loose from engagement from the status transition that gets loose to engagement, and final sliding assembly 2 stops to slide and all accomplishes through limiting stopper.When all quite big and moment of torsion that clutch need transmit is very big when the rotating speed of input shaft 1 and output ring 3, because the of short duration of action time will inevitably cause sliding assembly 2 and limiting stopper generation sharp impacts.This collision ghost image rings the safety and the working life of equipment.Clutch adopts two-way oil pressure damping sort this problem out.
In the present embodiment, suppose that clutch is in never engagement in the engagement transition process.The Thrust ring of sliding assembly 2 in damping cavity will be earlier through one section free clearance, because lubricant oil after this only can overflow from Thrust ring top micro-gap, it produces the heavy damping effect to sliding assembly 2.Simultaneously clutch designs appropriate free clearance make produce the heavy damping effect before the click structure throw off, to guarantee bringing overload for the click structure.Otherwise damping cavity also can be brought into play same effect when throw-out-of clutch.10 is free clearance among the figure.
As shown in Figure 3, inevitable relatively large in the present embodiment as its volume of clutch and the quality of transmitting large torque, directly adopt the click structure that enough moment of torsion and thrust can't be provided, so increase the engagement that a relay clutch triggers main clutch tooth 7.At first the click structure by light weight makes lighter relatively relay clutch engagement, accomplishes the engagement of main clutch tooth 7 then through screw key more solid on the relay clutch 4.
Clutch output terminal speed is greater than input end, and clutch does not mesh (Fig. 3 first half), and the click structure is not moved; When the input end spinner velocity increases, and click structure action relay clutch begins engagement when surpassing output terminal; When relay clutch completion engagement, the main clutch tooth 7 on output terminal and the main sliding assembly 2 is accomplished centerings each other and is also begun engagement; Servo clutch this moment tooth 7 transmitting torques, main screw key 4 promotes main sliding assembly 2 makes winner's clutch tooth 7 steadily mesh (servo clutch tooth 7 is progressively thrown off in this process); In main clutch tooth 7 engagement processes, damping cavity produces damping function simultaneously, to avoid the parts collision and to damage the state of clutch such as Fig. 3 lower half portion when meshing fully.Get loose process and engagement process of clutch is similar.
