Abstract
The invention provides a speed limiter which comprises a moving shaft, a larger cylindrical gear, a small cylindrical gear, a large bevel gear, a small bevel gear, a spoke, sliding blocks and friction plates, wherein the large cylindrical gear is arranged on the moving shaft, the small cylindrical gear is engaged with the large cylindrical gear, the large bevel gear is arranged at the other end of a small cylindrical gear shaft, the small bevel gear is engaged with the large bevel gear, the spoke is arranged at the other end of a small bevel gear shaft, the sliding blocks are arranged on the spoke, and the friction plates are arranged at positions corresponding to the end parts of the sliding blocks; circular motion of the moving shaft can be transferred to the spoke, and the sliding blocks are in contact with the friction plates at the positions corresponding to the end parts under the action of centrifugal force to generate friction force; a speed required to be limited is set by setting the transmission ratio of the gears; and when the speed is reached, the friction force reaches a critical value and can be reversely acted on the moving shaft to limit the speed. With the adoption of the speed limiter, the speed can be automatically limited under the condition of no need of external braking force, and the speed limiter has effects of energy saving and environmental friendliness.
Description
Technical field
The present invention relates to a kind of speed limiting device.
Background technique
Need to carry out speed limit to the object in motion in many occasions.Current speed limiting device is generally the function that reaches speed limit by applying the external force contrary with moving direction, not only complex structure but also because want dynamic source and consume certain energy.
Summary of the invention
The object of this invention is to provide a kind of simple in structure, speed limiting device that can automatic speed-limiting.
In order to achieve the above object, the technical solution adopted in the present invention is: comprise travel axis, big column gear, small cylinder gear, bevel gear wheel, bevel pinion, spoke, slide block and friction plate, wherein big column gear is arranged on travel axis, small cylinder gear engages with big column gear, the other end of small cylinder gear axle is installed bevel gear wheel, bevel pinion engages with bevel gear wheel, the other end of small coning gear shaft is provided with spoke, spoke is provided with slide block, be provided with friction plate with the corresponding part, end of slide block, be provided with spring in spoke bottom, be provided with friction plate with the corresponding part, bottom of slide block, be provided with keep plate on spoke top, the friction plate of the friction plate of described slider bottom corresponding part and corresponding part, slide block end is 60 ° of angles, the material of described friction plate is Fe based wear-resistant alloy, this alloy is by Cu3.3wt%, V0.87wt%, Mn10.6wt%, Cr6.44wt%, C8.89wt%, Si7.31wt%, P0.06wt%, surplus is that the granularity of Fe is 200 object powder through mixing, compacting, and sintering forms at 1285 DEG C.
Owing to having adopted technique scheme, the circular movement of travel axis can be delivered on spoke, slide block contacts with the friction plate of establishing in corresponding part, end and produces frictional force under the effect of centrifugal force.Recently set by the transmission of setting gear the speed that needs speed limit, in the time reaching this speed, frictional force reaches critical value, can react on travel axis, and its speed is limited.The present invention can realize automatic speed-limiting in the situation that not needing additional braking force, has the effect of energy-conserving and environment-protective, also have simultaneously simple in structure, easy to use, practicability is high, with low cost wait beneficial effect.
Brief description of the drawings
Fig. 1 is the schematic diagram of a kind of mode of execution of speed limiting device of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, speed limiting device of the present invention comprises travel axis 1, big column gear 2, small cylinder gear 3, bevel gear wheel 4, bevel pinion 5, spoke 6, slide block 7 and friction plate 8, wherein big column gear 2 is arranged on travel axis 1, small cylinder gear 3 engages with big column gear 2, the other end of small cylinder gear 3 axles is installed bevel gear wheel 4, bevel pinion 5 engages with bevel gear wheel 4, the other end of bevel pinion 5 axles is provided with spoke 6, spoke 6 is provided with slide block 7, is being provided with friction plate 8 with the corresponding part, end of slide block 7.Be provided with spring 9 in spoke 6 bottoms, being provided with friction plate 10 with the corresponding part, bottom of slide block 7, be provided with keep plate 11 on spoke top, the friction plate 10 of slide block 7 corresponding parts, bottom is 60 ° of angles with the friction plate 8 of slide block 7 corresponding parts, end.
Speed limiting device of the present invention can be delivered to the circular movement of travel axis 1 on spoke 6, and slide block 7 contacts with the friction plate 10 of establishing in corresponding part, end and produces frictional force under the effect of centrifugal force.Recently set by the transmission of setting gear the speed that needs speed limit, in the time reaching this speed, frictional force reaches critical value, can react on travel axis 1, and its speed is limited.The present invention can realize automatic speed-limiting in the situation that not needing additional braking force, has the effect of energy-conserving and environment-protective.Be provided with keep plate 11 size of manual tune frictional force as required by spoke 6 tops, further speed limit or braking.The friction plate 10 of slide block 7 corresponding parts, bottom is 60 ° of angles with the friction plate 8 of slide block 7 corresponding parts, end, can make slide block automatically produce the power to end and bottom, strengthens frictional force, strengthens the effect of speed limit.Also have simultaneously simple in structure, easy to use, practicability is high, with low cost wait beneficial effect.
The material of friction plate of the present invention is Fe based wear-resistant alloy, this alloy is by Cu3.3wt%, V0.87wt%, Mn10.6wt%, Cr6.44wt%, C8.89wt%, Si7.31wt%, P0.06wt%, the granularity that surplus is Fe is 200 object powder through mixing, suppressing, and sintering forms at 1285 DEG C.Adopt this Fe based wear-resistant alloy as friction plate, not only can make speed limiting device of the present invention can provide reliable and stable frictional force in the time reaching critical velocity, thereby keep constant speed to decline, and can prevent stuck can not trouble-free operation the sliding because the high temperature that high-speed motion produces makes friction plate distortion.In addition, also have preparation process simple, product performance conformity is better, is difficult for corrosion and loses efficacy, the lower and less advantage of noise of cost.Ensure that to greatest extent this speed limiting device has safety, stability.
