The utility model resolves the problems of abrasion and oil leakage which are caused when the elastic damping coupler is connected with a single brace motor or a diesel engine, thereby enhancing the service performance and lifetime of the coupler, reinforcing the operating stationarity, reliability and safety of a power system.
Description
Technical field
The utility model belongs to the railway locomotive technical field, especially relates to a kind of elastic damping coupler that is used on single support motor.
Background technique
Along with deepening continuously of engine design, the torsional vibration problems of engine power assembly more and more induces one to pay attention to.Suppressing torsional vibration, or dangerous resonant transfer is arrived outside the engine operation speed range, is necessary.
At present, great majority are used to connect the elastic damping coupler of two ends fixed structure (as diesel engine and generator), as Fig. 1, shown in Figure 3, splined shaft 1 one ends have flange, the coaxial packing holder 4 that is fixed with of the other end, side plate 5 and active flange 2 are with equally distributed intermediate mass 9, reed group 7 clamp, and be sleeved on the splined shaft 1 at interval in mesosphere 10 and the mesosphere.Side plate 5, intermediate mass 9, active flange 2 are fastenedly connected by bolt 11.Side plate 5 is near splined shaft flange one sides, and and splined shaft between be provided with O RunddichtringO 6.Splined shaft 1 is an output block, and the flange on the splined shaft 1 links to each other with diesel engine, and passive flange 3 is connected with generator.
Generator generally is divided into single support motor and dual-gripper motor.In axle system, if generator is single support motor, the support of generator will partly rely on shaft coupling.In this case, because generator is heavier, directly influence is, generator is in use oppressed initiatively flange 2, make initiatively flange 2 and splined shaft 1, packing holder 4 direct monolateral contacts, cause the wearing and tearing aggravation, cause that axle is that axis centering changes, and has more increased the not stationarity of whole system's operation.Simultaneously, also influenced cooperating of splined shaft 1 and side plate 5, make splined shaft 1 axle journal with side plate 5 monolateral contacts, strengthen the decrement of compressing rubber O RunddichtringO 6, just cause shaft coupling O RunddichtringO 6 and side plate 5 wearing and tearing to strengthen easily, 6 sealings of O RunddichtringO are bad, and leakage of oil takes place, also can cause 7 wearing and tearing aggravation or the fractures of shaft coupling reed when situation is serious, influence the safe operation of power system.
The model utility content
The purpose of this utility model provides and a kind ofly can effectively solve the elastic damping coupler that is connected occurring wear and leakage of oil problem with single support motor, diesel engine.
The technical solution of the utility model is: a kind of single support motor elastic damping coupler, comprise the coaxial packing holder that is connected on the other end end face of the flanged (FLGD) splined shaft of an end and this splined shaft, and be sleeved on side plate on the splined shaft, the reed group, intermediate mass and active flange, in the reed group, intermediate mass is with mesosphere outward, and at side plate with initiatively between the flange, intermediate mass in the mesosphere is evenly separated the reed group, the inner of reed group embeds in the keyway of splined shaft, side plate, intermediate mass, initiatively flange connects by bolton, be provided with rolling bearing between splined shaft and active flange, this rolling bearing exterior edge face is by the packing holder axial limiting.Between rolling bearing and splined shaft and the active flange is Spielpassung.
The utility model is installed in rolling bearing between splined shaft and the active flange, and making initiatively, flange does not directly contact with splined shaft, packing holder.Rolling bearing can bear radial and axial load, and has very advantages of higher of the rotating speed of permission.Aspect centering, rolling bearing has certain self-aligning ability, especially at the Bearing Installation seat, be under the situation of splined shaft good concentricity, can increase the stationarity of shaft coupling running, so also just remedy single support motor deficiency in this respect, solved flange and packing holder, splined shaft wear problems.Simultaneously,, also alleviated the uneven problem of decrement of O type rubber seal and side plate, effectively reduced the wearing and tearing of rubber seal, guaranteed the sealing effect in this gap, place owing to the supporting effect of rolling bearing.
As preferably, described rolling bearing is single-groove grooved ball bearing.
The beneficial effects of the utility model are: compare with the elastic damping coupler before improving, under the situation of torsional vibration characteristic that does not influence the diesel powered system and technical order, the wear-resisting leakproof of the utility model, improve the usability and the life-span of shaft coupling itself, strengthened running stability, reliability and the Security of power system.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As Fig. 2, shown in Figure 3, single support motor elastic damping coupler mainly is made up of splined shaft 1, active flange 2, passive flange 3, packing holder 4, side plate 5, O RunddichtringO 6, reed group 7, rolling bearing 8, intermediate mass 9, mesosphere 10, bolt 11.Splined shaft 1 one ends have flange, the coaxial packing holder 4 that is connected on the other end end face.Initiatively flange 2 is sleeved on the rolling bearing 8, and side plate 5, reed group 7, intermediate mass 9 and rolling bearing 8 are sleeved on the splined shaft 1, is Spielpassung between rolling bearing 8 and splined shaft 1 and the active flange 2.Side plate 5 is provided with 0 RunddichtringO 6 near splined shaft 1 flange one side between side plate 5 and splined shaft, rolling bearing 8 exterior edge faces are by packing holder 4 axial limitings.Intermediate mass 9 is evenly separated reed group 7, and makes in the keyway 12 of reed group 7 inner embedding splined shafts 1.Reed group 7, the intermediate mass 9 outer mesospheres 10 that are with, and at this side plate 5 with initiatively between the flange 2; Side plate 5, intermediate mass 9, active flange 2 are fastenedly connected by bolt 11.Passive flange 3 coaxial being connected on active flange 2 end faces.Rolling bearing 8 is selected single-groove grooved ball bearing for use in the present embodiment.
During work, the flange on the splined shaft 1 is connected with diesel engine, and passive flange 3 is connected with generator.When the coupling transmitting torque, splined shaft 1 rotates the intermediate mass 9 that drives in side plate 5, the mesosphere 10 and rotates together with reed group 7, active flange 2, rotates thereby drive passive flange 3; Simultaneously, rolling bearing 8 inner rings rotate with splined shaft 1, and initiatively flange 2 makes initiatively flange 2 and splined shaft 1 relative to rotating with rolling bearing 8 outer rings, and packing holder 4 is directly contact not.
