This shock attenuation gear includes rim and wheel hub, be provided with the former between wheel hub and the rim, back face of the rim is provided with the teeth of a cogwheel, along the even buffer that is provided with of circumferencial direction between wheel hub and the rim, buffer is including the buffing pad, spring and buffering cylinder, buffing pad fixed connection is on wheel hub, buffering cylinder fixed connection is on the rim, be provided with the slide opening on the buffing pad, the spring sets up in the slide opening, buffering cylinder and the cooperation of slide opening slidingtype, set up the oilhole that is linked together with the slide opening on the rim. The utility model has the advantages of shock resistance is good and the shock attenuation is effectual.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of gear, particularly a kind of damper gear.
Background technique
Gear refers to wheel rim to be had tooth and can engage the mechanical component transmitting motion and power continuously.Gear is the intermeshing mechanical parts having tooth of energy, and the application of gear in transmission has occurred very early.In 19 end of the centurys, generate cutting ratio juris and utilize the special purpose machine tool of this principle cutting and the appearance in succession of cutter, along with the development of producing, stationarity and the impact resistance of gear operation have received attention.
Gear rotational speed in existing power box is all higher, when its gear teeth and wheel rim be subject to the external world more energetically time, due to no-buffer in gear, external force can not be resisted, therefore the gear teeth easily damage or burst apart, and affect the transmission of the automobile of power, and in follow-up use, there is very large noise, also can cause damaging sooner with its meshed gears.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, provides a kind of damper gear with shock resistance and damping effect.
The purpose of this utility model realizes by following technical proposal: a kind of damper gear, comprise wheel rim and wheel hub, former is provided with between described wheel hub and wheel rim, described wheel rim arranged outside has the gear teeth, it is characterized in that, along the circumferential direction damping device is provided with uniformly between described wheel hub and wheel rim, described damping device includes buffing pad, spring and buffering cylinder, described buffing pad is fixedly connected on wheel hub, described buffering cylinder is fixedly connected on wheel rim, described buffing pad is provided with slide opening, described spring is arranged in slide opening, described buffering cylinder and slide opening sliding type coordinate, described wheel rim offers the oilhole be connected with slide opening.
When using this gear, because be along the circumferential direction provided with damping device equably between wheel hub and wheel rim, when gear receives outside larger impact force, wheel rim is driven to produce distortion, now wheel rim will compress buffering cylinder, buffering cylindrical compression spring, thus the gear teeth can not be caused to damage.After the impact force of outside disappears, owing to being subject to the effect of spring, the distortion of wheel rim resets, and well vibrations have been fallen in opposing.Lubricant oil can be passed through oilhole and enters in slide opening, makes the moment in damping device keep lubrication.
In above-mentioned a kind of damper gear, between the diameter of described slide opening is 1.08 times to 1.1 times of buffering body diameter.Buffering cylinder can be made more easily to slide in slide opening.
In above-mentioned a kind of damper gear, a side of described former is arc shaped surface.This structure can strengthen the non-deformability of former itself, and indirectly increases the impact resistance of wheel rim and the gear teeth.
In above-mentioned a kind of damper gear, the material of described buffing pad is No. 45 steel, and the material of buffering cylinder is 60Si2Mn spring steel.
Compared with prior art, this damper gear has damping device, makes it have good shock resistance and damping effect.
Accompanying drawing explanation
Fig. 1 is the sectional structure schematic diagram of this damper gear.
In figure, 1, the gear teeth; 2, wheel rim; 3, former; 4, wheel hub; 5, buffing pad; 6, spring; 7, cylinder is cushioned; 8, slide opening; 9, oilhole; 10, damping device.
Embodiment
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1, this damper gear comprises wheel rim 2 and wheel hub 4, former 3 is provided with between described wheel hub 4 and wheel rim 2, described wheel rim 2 arranged outside has the gear teeth 1, it is characterized in that, along the circumferential direction damping device 10 is provided with uniformly between described wheel hub 4 and wheel rim 2, described damping device 10 includes buffing pad 5, spring 6 and buffering cylinder 7, described buffing pad 5 is fixedly connected on wheel hub 4, described buffering cylinder 7 is fixedly connected on wheel rim 2, described buffing pad 5 is provided with slide opening 8, described spring 6 is arranged in slide opening 8, described buffering cylinder 7 and slide opening 8 sliding type coordinate, described wheel rim 2 offers the oilhole 9 be connected with slide opening 8.
In order to make, the buffering cylinder 7 in this damper gear is easier to slide in slide opening 8, between the diameter of its slide opening 8 is 1.08 times to 1.1 times of buffering cylinder 7 diameter.
In order to strengthen the non-deformability of former 3 itself, a side of its former 3 is designed to arc shaped surface.
In order to make buffing pad 5 have good erosion-resisting characteristics, it is material that its buffing pad 5 have employed No. 45 steel; In order to make buffering cylinder 7 have good toughness, the material of buffering cylinder 7 is 60Si2Mn spring steel.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
Although more employ the term such as the gear teeth 1, wheel rim 2, former 3, wheel hub 4, buffing pad 5, spring 6, buffering cylinder 7, slide opening 8, oilhole 9, damping device 10 herein, do not get rid of the possibility using other term.These terms are used to be only used to describe and explain essence of the present utility model more easily; The restriction that they are construed to any one additional is all contrary with the utility model spirit.
