Embodiment
Reference character: the outer ironware of ironware 2-2-second rubber layer 2-3-in 1-position-limitting pin assembly 2-rubber spring assembly 3-mass block 1-1-first rubber layer 1-2-pin ironware 2-1-.
Fig. 1-3 shows the torsion vibration absorber on transmission shaft that the utility model provides, this torsion vibration absorber comprises mass block 3, rubber spring assembly 2 and some position-limitting pin assemblies 1, described rubber spring assembly 2 press-fits in described mass block 3, some described position-limitting pin assemblies 1 press-fit respectively in described mass block 3, and described position-limitting pin assembly 1 respectively interference press-fits in described mass block 3.The utility model is spacing compact, and spacing place has vulcanized rubber to support, and mass block both can have been avoided not have significantly displacement, thus ensure that the life-span of product can not premature failure, when can solve again collision, abnormal sound occurs.By the degree of adaptability of rubber and position-limitting pin and interior ironware, improve the damping of product, thus improve anti-vibration performance.
The interference of described rubber spring assembly 2 press-fits in described mass block 3.
Described position-limitting pin assembly 1 is four.
Described position-limitting pin assembly 1 comprises pin ironware 1-2 and the first rubber layer 1-1, and described first rubber layer 1-1 is located at described pin ironware 1-2 surface, and the end face of described pin ironware 1-2 is provided with square groove.
Described rubber spring assembly 2 comprises interior ironware 2-1, the second rubber layer 2-2 and outer ironware 2-3, and described interior ironware 2-1 is located in described outer ironware 2-3, is provided with described second rubber layer 2-2 between described interior ironware 2-1 and described outer ironware 2-3.
Rubber spring assembly 2 is formed through sulfuration by inside and outside ironware, and inside and outside it, the coaxality in ironware 2-3 hole maintains very high precision; Its rubber part presents arc transition, avoids stress and concentrates, improve fatigue behaviour; It is radial spacingly controls within 0.5mm, well keeps the dynamic balance of product.
Position-limitting pin assembly 1 is formed through sulfuration by pin ironware 1-2 and rubber, and the rubber surface of sulfuration is curved, can realize well coincideing with interior ironware; Its rubber hardness can regulate as required, thus better controls radial displacement; Pin ironware has square groove, when assembling, can better keep the conformity in direction like this; Rubber spring assembly after sulfuration, by force fit mass block, magnitude of interference is equivalent to cut-off, and this operation can discharge the stress of rubber inside, solves the generation of rubber and ironware dropping situations to a great extent.
Control the cambered surface matching degree of ironware 2-1 in the cambered surface of pin vulcanized rubber and rubber spring assembly 2 well, the structural damping of product can well be regulated, thus make its Performance optimization.Four position-limitting pins and mass block are that interference press-fits, and by design force fit frock, can control the matching direction of pin and interior ironware accurately, also can better control the pressure-off power of pin.
Rubber spring assembly 2 amount of exercise biggest place, is connect by arc transition, can well realizes stress dispersion, be very helpful to the fatigue life of product.
Rubber spring assembly 2 is made up of inner and outer pipes, and wherein inner and outer pipes is all porose, accurately will be located during production by mould, ensures the coaxality in two holes; The outer wall of interior pipe and the inwall of outer tube scribble tackiness agent, and object allows rubber and ironware stick together firmly; Rubber spring assembly radial clearance controls within 1mm, and this requirement is ensured by mould.Because 1mm is thin especially, the core rod life-span may be shorter, so the core rod of 1mm just local.
Position-limitting pin assembly 1 is formed through sulfuration by pin ironware 1-2 and rubber, has the rubber pattern of position-limitting pin, before sulfuration, pin ironware scribbles tackiness agent, and after sulfuration, rubber will be bonded on pin ironware.
Mass block 3 is that machining forms, and strict guarantee hole size, ensure that 90 ° of distributions of four cinclides simultaneously; 90 ° of Spreading requirements of four cinclides are higher, and it can affect later stage pin and assemble cambered surface laminating degree that is rear and interior ironware.
After three parts are all finished, will control well and assemble this procedure.Need, first in rubber spring assembly press-in mass block, the coaxality of rubber spring assembly and mass block cinclides to be ensured by special pressing tool.After press-in, notice that whether the radial clearance of observing rubber spring is at below 0.5mm, if not, it is unreasonable to illustrate that cut-off controls.
By special tooling in position-limitting pin press-in mass block, what the degree of adaptability of pin rubber cambered surface and interior ironware will lean on frock recognizes to guarantee; The gap of pin rubber cambered surface and interior ironware will lean on the spacing of frock to ensure.
The torsion of product is ensure by controlling the torsional stiffness of product and the rotary inertia of mass block well admittedly frequently, and the damping of product ensures with coordinating of interior ironware by controlling the formula of rubber material, pin rubber cambered surface well.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
