Accompanying drawing explanation
Fig. 1 is the structural representation of Stirling motor shock-absorbing device in embodiments of the invention.
Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reaching purpose and be easy to understand with effect, following example combine accompanying drawing and are specifically addressed the Stirling motor shock-absorbing device of the present invention.
As shown in Figure 1, the Stirling motor shock-absorbing device 100 that the present embodiment provides axially is set in the periphery of lower house 200 of Stirling motor, and this Stirling motor shock-absorbing device 100 includes: the outside cover plates 6 of 4 two balancing weight groups 5 of 3 two plug groups of shock ring and cushion pad 7 and travel switch 8 bottom the middle shock ring of top shock ring 12.
Top shock ring 1 is looped around the tip position of lower house 200, and the flange portion of the head tank 300 of motor is pressed between top shock ring 1, and top shock ring 1 and press-fit block 400 and is fastened by screw nut assembly by press-fit block 400.
Bottom shock ring 3 is looped around the bottom position of lower house 200, and afterbody shock ring 3 is provided with not shown connection callosity in figure, connects callosity and is detachably fixed on external support thing.
Middle shock ring 2 and is looped around the centre position of lower house 200 between top shock ring 1 and bottom shock ring 3 equally.I.e. the middle shock ring of top shock ring 12 and bottom shock ring 3 coaxial surrounding are in the periphery of lower house 200, and all every an empty segment distance between the middle shock ring of top shock ring 12 and the inner side of this three of bottom shock ring 3 and lower house 200.
Two plug groups 4 are symmetricly set on the both sides of lower house 200, and two balancing weight groups 5 are symmetricly set on the both sides of lower house 200 and are installed on middle shock ring 2, and plug group 4 and balancing weight group 5 are arranged the most separately.
Each plug group 4 comprises some damping plugs 41, damping plug 41 runs through middle shock ring 2, and the two ends of damping plug 42 are connected respectively to top shock ring 1 and bottom shock ring 3, i.e. in screw-in top, the top shock ring 1 of damping plug 41, screw lock is passed through on bottom shock ring 3 in bottom.Every damping plug 41, at a upside piece spring 42a of suit of middle shock ring 2, is set with a spring 42b in the downside of middle shock ring 2.The two ends of spring 42a push against downside and the upside of middle shock ring 2 of top shock ring 1 respectively, and the two ends of spring 42b push against downside and the upside of bottom shock ring 3 of middle shock ring 1 respectively.
Each balancing weight group 5 has several fan-shaped damping pads 51, several fan-shaped damping pads 51 can be layering in the top and bottom of middle shock ring 2, it is fastenedly connected by securing member between fan-shaped damping pad 51 and middle shock ring 2, in the present embodiment, any one during securing member can be stud screw and this three of screw rod.
When several fan-shaped damping pads 51 are simultaneously attached to the top and bottom of middle shock ring 2, the vibration frequency of rectifiable motor.
It addition, the stroke direct proportionality of the power piston of middle shock ring 2 and the reciprocating stroke of fan-shaped damping pad 51 and motor internal.According to the law of conservation of momentum, when piston moves back and forth forward or backward, owing to the position of top shock ring 1 and bottom shock ring 3 immobilizes, middle shock ring 2 and the fan-shaped damping pad 51 being superimposed upon on middle shock ring 2 are under the resilient force of spring 42a and spring 42bd, form reverse resonance rapid decay vibrations with moving back and forth of piston, thus reach the effect of damping.
Cushion pad 7 is made up of rubber or plastics, is arranged on the bottom of the fan-shaped damping pad 51 of bottom, and follows fan-shaped damping pad 51 synchronous reciprocating motion.Travel switch 8 is arranged on the shock ring 3 of bottom and corresponding with cushion pad 7, and the contact of travel switch 8 is towards cushion pad.When the super many certain amplitude of the vibrations of Stirling motor, cushion pad 7 touches the contact of travel switch 8, travel switch Stirling motor is carried out stoppage protection.
Bottom shock ring 3 is provided with not shown protection nut in figure in the both sides of contact; and protect the height height less than contact of nut; cushion pad 7 only need to somewhat touch the contact of travel switch 8; the running forming travel switch 8 can be triggered, thus avoid the cushion pad 7 impact damage to contact.
Outside cover plate 6 is wrapped up in and is located at top shock ring 1, middle shock ring 2 and the outside of bottom shock ring 3.Prevent operator from causing peril because carelessly touching the Stirling motor shock-absorbing device of high-frequency vibration.
The effect of embodiment and effect
Stirling motor shock-absorbing device the most involved in the present invention is not merely defined in structure in an embodiment, any equivalent modifications carrying out the present invention and replacement the most all in scope of the invention.
In the present embodiment, each balancing weight group has several fan-shaped damping pads.But, in the Stirling motor shock-absorbing device that the present invention provides, each balancing weight group can also have several cylindrical snubber blocks, when several cylindrical snubber blocks are installed in the anon-normal middle position of fan-shaped damping pad, can correct the degree of balance of Stirling motor.
