Description
Technical field
The utility model relates to and a kind ofly carries out the device of speed limit for winding mechanism, is specifically related to a kind of centrifugal governor, can be installed in the take-up of dust catcher, is used to limit the speed of the automatic recovery of dust catcher electric wire.
Background technology
The power line of dust catcher is longer usually, is the convenience of depositing and carrying, and when not using, the electric wire of dust catcher need be received in the shell of the dust collector.Dust catcher in the market has auto take-up more.The common structure of this class auto take-up is on the ratchet of winding line wind spring to be set, during use, extend to suitable length by the ratchet screens to guarantee line, during recovery, after ratchet is threaded off, utilize the elastic force of wind spring that ratchet is rotated, recovery line, thereby the trouble of removing artificial spiral, take-up from.
Yet there is intrinsic defective in said structure.Because the active force of wind spring, the speed that ratchet drives the line backrush increases gradually, if the line that uses is longer, in case the free end of line is released, will reach bigger backrush speed, thus human body is caused potential security threat.In addition,, also can produce stronger impulsive force during its quick backrush, influence the useful life of auto take-up auto take-up itself even the termination of line does not bump against the people.
At the problems referred to above, those skilled in the art attempts existing auto take-up is improved, to realize the restriction to automatic take-up speed.At present, the speed-limiting device that report is arranged is to adopt the viscous speed limit, promptly utilizes the material (as damping grease) with big viscosity to produce resistance, and pipeline backrush speed is restricted.Yet on the one hand, no matter backrush speed how, viscosity resistance exists all the time, if select for use the viscosity of material excessive, can cause the end can not automatic drawing back, and viscosity is too small, does not have suitable speed limit effect again; On the other hand, because the changes of seasons or the change of region, the serviceability temperature of auto take-up differs greatly, and causes the variation of material viscosity, thereby is difficult to guarantee obtain when auto take-up used with occasion in the different time more consistent speed limit effect.
Summary of the invention
The utility model purpose provides a kind of centrifugal governor that is used for the dust catcher take-up, can cooperate with the ratchet of electric wire auto take-up on the dust catcher, carries out effective speed limit when the backrush speed of auto take-up is about to surpass lsafety level.
For achieving the above object, the technical solution adopted in the utility model is: a kind of centrifugal governor that is used for the dust catcher take-up, comprise the drive plate, gear and the centrifugal pan that are provided with internal tooth, described drive plate is connected transmission through gear with centrifugal pan, the centrifugal pan upper edge circumferentially is evenly equipped with 3 to 8 centrifugal, each centrifugal radially slides with centrifugal pan and to be connected and spacing by centrifugal pan through a spring, and the gearratio of described gear is between 3～10.
Technique scheme realizes that the mode of speed limit is, in use, drive plate is fixedlyed connected with the ratchet of auto take-up, in the installation site, the inner walls of dust catcher cooperates with described centrifugal outer end, constitutes rubbing surface, because each centrifugal is provided with spring, under the initial condition, there is not active force between centrifugal rubbing surface and the auto take-up inner walls, after ratchet rotates, centrifugal on the centrifugal pan is subjected to the outside slippage of action of centrifugal force, contact spacingly with the auto take-up inner walls, the elastic force that centrifugal force deducts spring is pressure between the two, because centrifugal pan is when rotating, and between the auto take-up inner walls sliding friction can take place, the size of this frictional force is directly proportional with above-mentioned pressure, thereby rotating speed is fast more, centrifugal force is big more, frictional force is also big more, thereby speed limit is also obvious more.
Yet in actual use, the speed limit that rubs between centrifugal and static housing can cause speed limit too big, and sometimes, the end section electric wire can not be regained fully, simultaneously, also must make amendment to the shell of the dust collector structure of installing, and adaptability is relatively poor.
Therefore, further technical scheme is:
In technique scheme, with the coaxial frictional disk that is provided with of drive plate, frictional disk is provided with the friction wall of extending the ring-type that constitutes to card one side, and friction wall and described each position, outer end of centrifugal are equipped with.At this moment, described centrifugal outer end is the rubbing surface that cooperates with friction wall, because each centrifugal is provided with spring, under the initial condition, there is not active force between the centrifugal rubbing surface and the friction wall of frictional disk, after ratchet rotated, centrifugal on the centrifugal pan was subjected to the outside slippage of action of centrifugal force, contacts spacing with friction wall, the elastic force that centrifugal force deducts spring is pressure between the two, owing to be provided with gear, centrifugal pan is different with the rotating speed of frictional disk, exists between the two to relatively rotate, sliding friction can take place between centrifugal and frictional disk, the size of this frictional force is directly proportional with above-mentioned pressure, thereby rotating speed is fast more, centrifugal force is big more, frictional force is also big more, thereby speed limit is also obvious more.Gear ratio by gear is set and change spring on centrifugal can be selected suitable speed restrictive block, and, because frictional disk is positioned at limiter of speed, not requiring for installation site periphery housing, adaptability is stronger.
In the technique scheme, described gear is an epicyclic transmission mechanism, comprise gear stand and a plurality of planetary gear, described planetary gear is rotationally connected with corresponding rotating shaft on the gear stand, planetary gear is peripheral to be meshed with the internal tooth of described drive plate, centrifugal pan rotating shaft one side is provided with gear ring, the gear ring engagement on planetary inner ring and the centrifugal pan.Thus, internal tooth on the drive plate and the gear ring on the centrifugal pan constitute two sun gears respectively, cooperate with a plurality of planetary gears to realize the speed change transmission.
Further technical scheme is provided with 3 described planetary gears, and it is distributed in the drive plate, and described centrifugal pan sliding sleeve is in the rotating shaft of drive plate.
Optimized technical scheme, the gearratio of described gear is between 4～6.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1. because limiter of speed described in the utility model has adopted centrifugal speed limit principle, therefore when the backrush speed of the electric wire retracting device of the dust catcher that has used this limiter of speed is very high, centrifugal will be elongated coupled spring, thereby contact the generation friction with frictional disk, make the rotary speed of drive plate and frictional disk descend, and the size of frictional force is relevant with rotating speed, rotating speed is big more, the speed limit effect is obvious more, thus, can make the rotating ratio of retracting device more even;
2. the utility model utilizes gear that centrifugal pan and frictional disk are produced relative rotation, and obtain rational relative rotation speed by adjusting gearratio, thus, frictional disk can with the coaxial setting of drive plate, get final product work on the whole ratchet that directly is installed to auto take-up, can be adapted at using in the existing various dust catchers.
