Description

Permanent-magnet speed governor with poke-rod type air gap adjusting device
Technical field
The present invention relates to permanent magnetic speed-adjusting technical field more particularly to a kind of permanent magnetic speed-adjustings with poke-rod type air gap adjusting device Device.
Background technique
On 2 20th, the 1998 patent of invention ZL98802726.7 proposed of Magna Force Inc. of the U.S. disclose one kind forever Magnetic governor, structure such as Fig. 1, is mainly made of copper rotor, magnet rotor and air gap adjusting device.It is mounted on prime mover and load Between machine, the needs that can be run according to load machine adjust the air gap between copper rotor and magnet rotor by air gap adjusting device Size changes the revolving speed of load machine, and the revolving speed that motor is then kept constant is constant.
The air gap adjusting device of the permanent-magnet speed governor includes two push-pull mechanisms.First push-pull mechanism(See Fig. 1-2)10 are Barrel cam mechanism has one group of cam roller 12 to be charged into the arc-shaped cam slot 14 of outer cylinder 13 radially outward on inner cylinder 11, outside Cylinder 13 is fixedly connected a yoke 15 with basis, prevents its rotation, only it is allowed to move axially in reciprocal fashion.Inner cylinder 11 protrudes outward one Actuator arm 16 rotates inner cylinder 11 by manipulating this arm, and the cam roller on inner cylinder will pass through the promotion of the cam path on outer cylinder 13 Outer cylinder is being axially moved, and thus gives an offer axial force in the magnet rotor 21-22 that outer cylinder is fixedly connected.
Second push-pull mechanism(See Fig. 2-4)To be mounted on one group of rocker arm 24 on rotor 23 in fixed, these rocker arm both ends It is respectively installed in cam path in the roller 25 wherein moved, roller 25 is separately mounted to fix with magnet rotor and prominent magnet rotor Block part 26 on.When the magnet rotor for receiving axial force is close or leaves rotor 23 changes air gap 27, it just pushes and pulls rocker arm 24 swing on the bolts 28, and the other end of rocker arm draws or pushes therewith magnet rotor 21 close or leaves rotor 23, equally change gas Gap.Two push-pull mechanism combinations, when external electric operator pushes and pulls actuator arm, air gap 27-27 ' obtains identical change Become.
But above-mentioned air gap regulating mechanism, there are following deficiencies:
1, structure is more complicated.There are multiple cams and cam path cooperation, four rocker arms between barrel cam structure inner/outer tube Eight end cams slots cooperate respectively with eight rollers, many places movement node, motion credibility necessarily reduces.Between inner/outer tube Cam and cam path, the cam path of rocker arm and roller must be harmonious, motor coordination difficulty is big, it is easy to local mistake occur Degree abrasion is blocked or even the failure for the components that are damaged.
2, manufacturing cost is high.Barrel cam structure is also increased accordingly by inner and outer cylinder set, radial dimension, further increases material Expense.The large scale stairstepping inner hole of many places cam path, inner cylinder outer cylinder on inner cylinder, many places movement node of rocker arm require compared with More machining operations amounts, and the cam path on inner cylinder are located on cylindrical surface, need to use special machine tooling, processing charges With higher.So this push-pull mechanism manufacturing cost is higher.
3, manufacture difficulty is big.Multiple cam paths on inner cylinder must be uniformly distributed, and the cooperation with cam also must be tight, otherwise Will move it is unsmooth or even stuck, then, the requirement on machining accuracy of cam path says that height, difficulty of processing are big;The assembly of cam mechanism It is required that also higher, the assembly of cam path and roller on rocker arm is even more to coordinate mutually, precision-fit.So this push-and-pull machine Structure is less susceptible to manufacture.
Summary of the invention
The object of the present invention is to provide a kind of permanent-magnet speed governors with poke-rod type air gap adjusting device, and it is high to cancel manufacturing cost And the barrel cam mechanism easily to break down, it drives p-m rotor to do front and back along axial direction with succinct radial type lever body and moves It is dynamic, it realizes the automatic quick regulatory function of permanent-magnet eddy current speed regulation device, simplifies structure, reduce manufacturing cost, improve reliable in action Property.
To achieve the goals above, the technical scheme is that it is such:
Permanent-magnet speed governor with poke-rod type air gap adjusting device, including conductor rotor, p-m rotor, jackshaft and air gap tune Mechanism is saved, conductor rotor is connected with conductor side wheel hub, and the air gap regulating mechanism includes linear actuator, driving lever and adjusting Set, the adjusting set are connected with p-m rotor by permanent magnetism side wheel hub, and permanent magnetism side wheel hub is slidably connected with jackshaft, jackshaft One end connects telophragma;One end of the driving lever is U-shaped opening, and hinged with the outer wall of adjusting set, the midpoint of driving lever is articulated with branch The end of strut, support rod are fixed on support one, and the other end of driving lever is articulated with the piston end of linear actuator;The straight line Driver is vertically fixed on support one;The other end of the jackshaft is connected by bearing block with support two.
Be uniformly provided with multiple idle pulleys around circumferential on the telophragma, each idle pulley respectively be located at permanent magnetic disk one and permanent magnetic disk Rack gear engagement on two makes the advance and retreat synchronous with respect to telophragma realization with permanent magnetic disk two of permanent magnetic disk one.
It is equipped with bearing between the adjusting set and permanent magnetism side wheel hub, is provided with sealing ring on the outside of bearing.
The bearing is a pair of angular contact ball bearing being arranged back-to-back.
The adjusting set is equipped with pump nozzle.
The sealing ring is lip-type packing.
The linear actuator is one of cylinder, electric pushrod or hydraulic cylinder.
The longitudinal direction of the driving lever is equipped with reinforcing rib.
The support one and support two are all set on pedestal.
Compared with prior art, the beneficial effects of the invention are as follows:
1)The barrel cam mechanism that manufacturing cost is high and easily breaks down is eliminated, with succinct radial type lever body band Dynamic p-m rotor is moved forward and backward along axial direction, simplifies structure, radial type lever body is laborsaving lever structure, relative to existing Inner/outer tube cam structure, have the characteristics that acting force arm is big and maximum weighted point is external, enough force balances can be generated The vibration of p-m rotor, and damageable zone is easier examination and maintenance, security reliability with higher.
2)Air gap between the p-m rotor and conductor rotor of permanent-magnet speed governor is adjusted using rack gear idler mechanism, and rack gear is lazy The movement clearance for taking turns mechanism is smaller than swing link cam structure, therefore can effectively mitigate the vibration and noise in permanent-magnet speed governor operating, More acurrate and stable air gap is provided to adjust.
3)Mechanism can cooperate a variety of linear actuator drivings such as cylinder, electric pushrod, hydraulic cylinder, be applicable in a variety of applied fields It closes, is able to achieve the air gap of permanent-magnet speed governor quick regulatory function automatically.
