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 carry out speed limit to the object in the motion in many occasions.Present speed limiting device generally is through applying the function that the external force opposite with moving direction reaches speed limit, not only complex structure but also consume certain energy because want dynamic source.
Summary of the invention
The purpose 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 technological scheme that the present invention adopted is: comprise travel axis, big column gear, small cylinder gear, bevel gear wheel, bevel pinion, spoke, slide block and friction plate; Wherein the big column gear is installed on the travel axis, small cylinder gear and big column gear engagement, and the other end of small cylinder gear axle is installed bevel gear wheel; Bevel pinion and bevel gear wheel engagement; The other end of small coning gear shaft is provided with spoke, and spoke is provided with slide block, is provided with friction plate in the corresponding part, end with slide block.
As improvement of the present invention, be provided with spring in the spoke bottom, be provided with friction plate in corresponding part, bottom with slide block, be provided with keep plate on spoke top.
As further improvement of the present invention, the friction plate of the friction plate of said slider bottom corresponding part and corresponding part, slide block end is 60 ° of angles.
The material of said friction plate is the Fe based wear-resistant alloy, and this alloy is by Cu 3.3wt%, V0.87wt%; Mn 10.6wt%, Cr6.44wt%, C8.89wt%; Si 7.31wt%; P0.06wt%, surplus is that the granularity of Fe is-200 purpose powder through mixing, compacting, and forms at 1285 ℃ of following sintering.
Owing to adopted said structure, can the circular movement of travel axis be delivered on the spoke, slide block contacts generation frictional force with the friction plate of establishing in the corresponding part, end under action of centrifugal force.The speed that needs speed limit is recently set in transmission through setting gear, and when reaching this speed, frictional force reaches critical value, can react on the travel axis, makes its speed obtain restriction.The present invention can realize automatic speed-limiting under the situation that need not add braking force, effect in energy saving and environmental protection is arranged, and also has simple in structurely, easy to use simultaneously, and practicability is high, the beneficial effect that waits with low cost.
Description of drawings
Fig. 1 is the schematic representation of a kind of mode of execution of speed limiting device of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is described further.
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 installed on the travel axis 1, small cylinder gear 3 and 2 engagements of big column gear, and the other end that small cylinder gear is 3 is installed bevel gear wheel 4; Bevel pinion 5 and bevel gear wheel 4 engagements; The other end that bevel pinion is 5 is provided with spoke 6, and spoke 6 is provided with slide block 7, is provided with friction plate 8 in the corresponding part, end with slide block 7.Be provided with spring 9 in spoke 6 bottoms, be provided with friction plate 10 in the corresponding part, bottom with slide block 7, be provided with keep plate 11 on spoke top, the friction plate 10 of corresponding part, slide block 7 bottom is 60 ° of angles with the friction plate 8 of corresponding part, slide block 7 end.
Speed limiting device of the present invention can be delivered to the circular movement of travel axis 1 on the spoke 6, and slide block 7 contacts with the friction plate of establishing in the corresponding part, end 10 under action of centrifugal force and produces frictional force.The speed that needs speed limit is recently set in transmission through setting gear, and when reaching this speed, frictional force reaches critical value, can react on the travel axis 1, makes its speed obtain restriction.The present invention can realize automatic speed-limiting under the situation that need not add braking force, effect in energy saving and environmental protection is arranged.Be provided with keep plate 11 size of manual tune frictional force as required through spoke 6 tops, further speed limit or braking.The friction plate 10 of corresponding part, slide block 7 bottom is 60 ° of angles with the friction plate 8 of corresponding part, slide block 7 end, can make slide block produce the power to end and bottom automatically, strengthens frictional force, strengthens the effect of speed limit.Also have simple in structurely, easy to use simultaneously, practicability is high, the beneficial effect that waits with low cost.
The material of friction plate according to the invention is the Fe based wear-resistant alloy, and this alloy is by Cu 3.3wt%, V0.87wt%; Mn 10.6wt%, Cr6.44wt%, C8.89wt%; Si 7.31wt%; P0.06wt%, surplus is that the granularity of Fe is-200 purpose powder through mixing, compression moulding, and forms at 1285 ℃ of following sintering.Adopt this Fe based wear-resistant alloy as friction plate; Not only can make speed limiting device of the present invention when reaching critical velocity, reliable and stable frictional force can be provided; Thereby keep constant speed to descend, and can prevent because the high temperature that high-speed motion produces makes the friction plate distortion and stuck can not trouble-free operation sliding.In addition, it is simple also to have preparation process, and the product performance conformity is better, be difficult for corrosion and lost efficacy, cost low with the less advantage of noise.It is safe, stable to have guaranteed that to greatest extent this speed limiting device has.
