Description

弹性阻尼联轴节 Elastic damping coupling

技术领域technical field

本发明涉及联轴节技术领域，更具体地说，涉及一种万向轴用压力供油的弹性阻尼联轴节。The invention relates to the technical field of shaft couplings, in particular to an elastic damping shaft coupling with pressure oil supply for a cardan shaft.

背景技术Background technique

随着发动机设计的不断发展，发动机动力装置的扭转振动问题越来越引人重视。很多情况下，抑制扭转振动或将危险共振转移到发动机工作转速范围之外，是很有必要的。例如适用于连接一端为固定结构(如柴油机)、一端是为活动结构(如万向轴)的弹性阻尼联轴节。With the continuous development of engine design, the problem of torsional vibration of engine power plant has attracted more and more attention. In many cases it is necessary to suppress torsional vibrations or to shift dangerous resonances outside the engine operating speed range. For example, it is suitable for elastic damping couplings where one end is a fixed structure (such as a diesel engine) and the other end is a movable structure (such as a cardan shaft).

请参阅图1，图2，图1为现有的弹性阻尼联轴节的结构示意图，图2为图1沿C-C线对的剖视图。Please refer to Fig. 1 and Fig. 2. Fig. 1 is a schematic structural diagram of an existing elastic damping coupling, and Fig. 2 is a sectional view along line C-C in Fig. 1 .

其中，1为花键轴，2为法兰盘，3为盖板，4为密封圈座，5为侧板，6为O型密封圈，7为簧片组。Among them, 1 is a spline shaft, 2 is a flange, 3 is a cover plate, 4 is a sealing ring seat, 5 is a side plate, 6 is an O-shaped sealing ring, and 7 is a reed group.

法兰盘2和侧板5通过螺栓将均匀分布的由支撑块分割的楔形簧片组7夹持住，一端带有法兰的开有中心孔的花键轴1从侧板5一侧插入，每个簧片组7的内端嵌入花键轴1的键槽内。盖板3固定在所述法兰盘2上，一端伸入花键轴1的中心孔内的密封圈座4通过螺钉固定在花键轴1上，且其上设有容纳密封圈的槽，以使得和法兰盘2通过密封圈密封，防止漏油。弹性联轴节的外部构件法兰盘2与柴油机的输出曲轴连接，花键轴1的大直径端(法兰端)与万向轴相连接，联轴节外部构件法兰盘2通过簧片组7传递扭矩到花键轴1的小直径端的花键槽内，从而通过花键轴把动力传递到万向轴。The flange plate 2 and the side plate 5 clamp the evenly distributed wedge-shaped reed group 7 divided by the support block through bolts, and the spline shaft 1 with a flange at one end and a central hole is inserted from the side plate 5 , the inner end of each reed group 7 is embedded in the keyway of the spline shaft 1 . The cover plate 3 is fixed on the flange plate 2, and the sealing ring seat 4, which one end extends into the central hole of the spline shaft 1, is fixed on the spline shaft 1 by screws, and a groove for accommodating the sealing ring is arranged on it. So that it is sealed with the flange plate 2 by a sealing ring to prevent oil leakage. The flange 2, the external member of the elastic coupling, is connected to the output crankshaft of the diesel engine, the large diameter end (flange end) of the spline shaft 1 is connected to the cardan shaft, and the flange 2, the external member of the coupling, passes through the reed Group 7 transmits torque to the spline groove at the small diameter end of spline shaft 1, thereby transmitting power to the cardan shaft through the spline shaft.

万向轴的重量将部分依靠弹性阻尼联轴节支撑，联轴节起不到限制万向轴轴向伸缩和径向蹿动的作用。在这种情况下，直接的影响就是，万向轴在使用过程中发生轴向和径向蹿动，引起侧板内孔和O型密封圈6磨损加剧，增加了整个轴系运行的不平稳性。同时，影响了花键轴1与侧板5的配合精度，使花键轴1轴颈外圆同侧板5内孔单边接触，加大压缩O型密封圈6的压缩量，导致联轴节O型密封圈6与侧板5内孔磨损加大，O型密封圈6密封不好，O型密封圈6处花键轴1与侧板5内孔的间隙发生漏油，情况严重的时候还会导致联轴节簧片7磨损加剧或者断裂，影响动力系统的安全运行。通过密封圈座4和花键轴1固定为一体，以及将花键轴1插入到侧板5内，另外又将密封圈座4和法兰盘2紧密贴合，已经能够避免花键轴1的径向蹿动。但是花键轴1的轴向蹿动一直是困扰业界的问题。The weight of the cardan shaft will be partially supported by the elastic damping coupling, and the coupling will not be able to limit the axial expansion and radial movement of the cardan shaft. In this case, the direct impact is that the axial and radial movement of the cardan shaft during use will cause the wear of the inner hole of the side plate and the O-ring 6 to increase, and increase the instability of the entire shaft system. sex. At the same time, it affects the matching accuracy of the spline shaft 1 and the side plate 5, so that the outer circle of the spline shaft 1 journal is in unilateral contact with the inner hole of the side plate 5, and the compression amount of the O-ring 6 is increased, resulting in coupling The wear of the O-ring 6 and the inner hole of the side plate 5 increases, the sealing of the O-ring 6 is not good, and oil leakage occurs in the gap between the spline shaft 1 and the inner hole of the side plate 5 at the O-ring 6, and the situation is serious Sometimes it will also cause the coupling reed 7 to wear aggravated or break, which will affect the safe operation of the power system. By fixing the sealing ring seat 4 and the spline shaft 1 as one, inserting the spline shaft 1 into the side plate 5, and fitting the sealing ring seat 4 and the flange 2 tightly, the spline shaft 1 can be avoided. radial movement. However, the axial movement of the spline shaft 1 has always been a problem in the industry.

In this way, when the spline shaft is subjected to axial force, the spring force of the spring can offset most of the axial force, thereby reducing the defects caused by the axial movement of the spline shaft due to the axial force. The invention effectively solves the problems of wear and oil leakage in the connection between the coupling, the cardan shaft and the diesel engine, improves the service performance and life of the coupling itself, and enhances the running stability, reliability and reliability of the power system. safety.

本发明还包括套装在弹簧座9上的垫圈8，该垫圈8为两个，且分别位于所述弹簧10的两端。通过设置垫圈8，使得弹簧10更加均匀的抵消万向轴施加给花键轴1的轴向力。垫圈8优选为青铜垫圈。The present invention also includes two washers 8 sleeved on the spring seat 9 , and the washers 8 are located at two ends of the spring 10 respectively. By arranging the washer 8, the spring 10 can more evenly counteract the axial force applied to the spline shaft 1 by the cardan shaft. The gasket 8 is preferably a bronze gasket.

弹簧座9通过螺钉和所述盖板3固定在一起。通过将弹簧座9和盖板3固定在一起，而且弹簧座9得一端伸入挡圈11的适配孔内，而挡圈11又靠花键轴1轴向定位。所以在花键轴1径向窜动时，必然会带动挡圈11径向窜动，而挡圈11必然会带动弹簧座9和盖板3径向窜动，而盖板3是固定在法兰盘上，法兰盘在径向是没有自由度的，所以花键轴1也在径向没有自由度，从而避免了花键轴1径向的蹿动。The spring seat 9 is fixed together with the cover plate 3 by screws. The spring seat 9 and the cover plate 3 are fixed together, and one end of the spring seat 9 extends into the fitting hole of the retaining ring 11 , and the retaining ring 11 is axially positioned by the spline shaft 1 . Therefore, when the spline shaft 1 moves radially, it will inevitably drive the retaining ring 11 to move radially, and the retaining ring 11 will inevitably drive the spring seat 9 and the cover plate 3 to move radially, and the cover plate 3 is fixed on the flange. On the flange plate, the flange plate has no degree of freedom in the radial direction, so the spline shaft 1 also has no degree of freedom in the radial direction, thereby avoiding the radial movement of the spline shaft 1 .

盖板8上开设有环形回油槽，可以有效的解决压力供油后的回油问题，只要在该分布圆上曲轴有回油孔就可以很好的保证联轴节的回油。由于限制了花键轴1的轴向和径向运动，缓解了O型橡胶密封圈6与侧板5内孔的压缩量不均匀的问题，有效的降低了橡胶密封圈的磨损，保证了该处间隙的密封效果，提高了联轴节的使用寿命，增加了整个轴系运行的平稳性。The cover plate 8 is provided with an annular oil return groove, which can effectively solve the oil return problem after pressure oil supply, as long as the crankshaft has an oil return hole on the distribution circle, the oil return of the coupling can be well guaranteed. Due to the limitation of the axial and radial movement of the spline shaft 1, the problem of uneven compression between the O-shaped rubber sealing ring 6 and the inner hole of the side plate 5 is alleviated, the wear of the rubber sealing ring is effectively reduced, and the The sealing effect of the gap at the joint improves the service life of the coupling and increases the stability of the entire shaft system.
